1. Introduction

COCONUT comes to meet the requirements of the next generation access networks with

improved features with respect to reach, bandwidth, number of users and cost-effectiveness.

COCONUT aspires to influence the definition of NGPON3. In particular it tries to introduce

coherent detection technologies in access networks in an effort to support high-bandwidth full

and shared wavelength services to end users like businesses, residential users and mobile

traffic backhauling.

In terms of dissemination, the goal of the consortium is to clearly communicate its objectives

and achieved technology solutions to potentially interested parties with activities that targeted

both the research and the industrial community.

During the second year of the project the consortium counted 26 scientific articles in peer-

reviewed international journals and conferences, while 7 papers had been already submitted to

upcoming conferences. Moreover the COCONUT project was presented in three different

workshops. In addition targeted presentations were made to industry partners who are

potential end users of the technology under development in COCONUT.

During the second year of the project all partners updated their exploitation plans. Each

partner in this document presents more details of their exploitation plans and the identified

commercialisation prospects for the project outcomes. In addition, it is worth emphasizing

that 2 patents that were filed during the 1st year of the project, are now extended

internationally in order to protect globally the IPR developed within the project.

The consortium is following up all recent developments at the standardisation bodies and

plans to prepare a contribution with specific proposals about the possible adoption of

COCONUT related technologies/solutions at around the end of the project’s lifetime.

2. Dissemination Activities and Plans

To disseminate the project results and promote its visibility several actions were taken by the

different partners:

The project website has been regularly updated with all public information concerning

the project, including its public deliverables.

In addition to the website, project news has been communicated to the public through

various channels such as Twitter and RSS feeds.

Significant presence and presentation of the COCONUT concept and solutions at the

most relevant conferences and events in 2014.

Submission of scientific papers to the most significant journals in the field.

Presentations to potential end-users of the technology developed within COCONUT

2.1. Website

The website of COCONUT (www.ict-coconut.eu) acts as a point of reference both for the

external visitors and the consortium members. The content of the website is being regularly

http://www.ict-coconut.eu/



Page: 6 of 38

updated with information about the project concept, latest achievements, news and events.

Partner OPTRONICS, as the COCONUT dissemination leader, established and maintains the

COCONUT website. At the time of compiling this deliverable more than 14.000 visitors have

accessed our website. Apart from utilizing the project webpage as the main communications

channel, OPTRONICS has established a Twitter account (https://twitter.com/ict_coconut) and

an RSS feed to communicate the projects results, news and achievements to the interested

readership.

The COCONUT website contains a public area with:

Project Information

News and events

Publications

Public Deliverables

Information about the consortium

It also contains a restricted area with access only to the COCONUT partners. This area

enables the Consortium to manage the diffusion of the information and exchanges between

partners and contains a directory with the relevant files of the:

Working documents (Templates, Deliverables, Milestones and Task Detailed Work-

Plans)

Publications

Meeting Minutes

Project Grant

Administration Information

2.2. Website Statistics

The COCONUT website includes a visitor counter, which gives a rough indication of the

project diffusion to the wider public. By the end of the 2nd year of the project, the

COCONUT website has counted more than 14.000 visitors. However, to get more precise

conclusions, the website is registered to the Google analytics service since the 30th of April

2014.

Google Analytics provides statistical data regarding the website’s traffic. The data analysis of

the traffic information gives a better understanding on the effectiveness of the dissemination

activities. The traffic data can help the consortium identify weaknesses in the dissemination

activities and improve the dissemination strategy.

Figure 2 presents the total page views of the COCONUT website. The figure also highlights

the most important conferences and workshops that may impact the website traffic. The graph

indicates almost a linear behaviour over time and the website traffic build ups constantly. A

closer examination on the pageviews over time, identifies small steps which are correlated to

the project dissemination activities. The influence of most events is noticeable on the traffic of

COCONUT website. It is worth noticing that there was a significant influence on the website

traffic at the beginning of September, which is related to website update and maintenance that

attracted additional visitors.

Figure 2: Website total page views in time

Figure 3 presents the average pageviews during the most important dissemination events, in

comparison to the average pageviews for the total available period. The dissemination

activities of the COCONUT project during EUCNC were the most effective in terms of the

influence on the website traffic.

Figure 3: Influence of dissemination activities to website traffic

Figure 4 indicates that there is a high interest on the COCONUT website in Brazil. The CPqD

research centre in Sao Paolo is working on next-generation 10 Tbps optical systems based on

DWDM technology, and this might explain the increased number of visitors.

2.2.1. Conclusions and 3rd year Planning

The traffic analysis showed a significant diffusion of the COCONUT concept on the public.

The consortium will continue to disseminate the project by highlighting the project URL for

further references. The goal for the 3rd year of the project will be to increase the influence of

the dissemination activities in comparison to the metrics presented in this report.

Moreover the consortium will try to establish communication channels with the interested

parties all over the world and in particular with identified research groups, such as in Brasil.

Such dissemination activities could potentially develop some commercial benefits for our

industrial partners.

Albert Rafel

AIT organised and Dr. I. Tomkos Chaired an open international workshop (held at AIT’s

premises on May 9th 2014) under the auspices of COCONUT and other EU projects. The title

of the one-day workshop is “Optical Communication Systems and Networks: From Research

to Innovation”. This workshop brought together academia, industry, entrepreneurs, Venture

Capitalists and funding agencies working on telecommunications networks with an emphasis

on optical communication systems and networks. Speakers from universities and research

centres, companies, as well as the head of sector "Internet of Things and Optical Networks",

European Commission were invited. Prof. Ernesto Ciaramella (SSSA) and prof. Josep Prat

(UPC) were invited to present their views with the following talks:

- Josep Prat: “Next Generation Broadband Optical Access Networks”

- Ernesto Ciaramella: “How R&D activities between a major Company and a University

Lab can successfully flourish: the Pisa example of SSSA and Ericsson".

This workshop enabled interactions of the COCONUT partners with other EU projects but

also with the Greek telecom market and entrepreneurial ecosystem.

3. Exploitation Activities and Plans

The following section describes the exploitation plans and activities per consortium partner.

The plan of each partner for the exploitation of the COCONUT results was reported in detail

in the COCONUT DoW. Following the end of the 2nd reporting period in M24 this deliverable

summarizes the up-to-date status and any performed activities.

3.1. Patent Applications and Innovations

Although COCONUT just completed its second year, 2 inventions developed within

COCONUT have shown substantial innovation to be protected by a patent. These patents

have been filed nationally during the first year of the project. During the second year both

patents have being extended for international filing.

3.2. Exploitation plans per industrial partner

3.2.1. BT

After the second year of activities in the COCONUT Project, BT is still (if not more)

confident that some of the technologies may fit in the current and future Standardisation

efforts.

FSAN and ITU-T Q2/SG15 are currently developing the Recommendations for the NG-PON2

system. An initial document for the PMD Layer has just been finally approved (G.989.2) and

another initial document for the TC-Layer (G.989.3) is currently the main activity focus and it

is expected to be consented by July 2015 during the next ITU-T SG15 plenary meeting.

BT and AIT collaborated towards possible contributions to the TC-Layer studies (that was

beyond the scope of the DoW) during the second year of the COCONUT project, i.e. during

2014. Specifically on the activation process and required times to activate non-calibrated

ONUs, where the ONU transmitting wavelengths needs tight control and guidance from the

OLT in order to hit the right OLT channel (upstream wavelength). Due to lack of resources

and the need to prioritise the focus on the technical activities that are covered by the DoW,

this activity did not concluded with a specific standards contribution.

FSAN and ITU have already started working towards an Amendment of G.989.2 to finalise

certain aspects that were not considered as essential for the first approved document, which

will include further aspects of the PMD layer such as an Auxiliary Management & Control

Channel to activate non-calibrated ONUs within the TWDM-PON system, and to carry all

management & control traffic for the PtP WDM channels that require complete transparency

for the client traffic (e.g. CPRI used in mobile Front-Haul). The activities on the G989.2 Am1

and, similarly, for the G.989.3 Am1, which opens the opportunity for COCONUT to

contribute to these efforts.

The studies on coherent technologies for both the ONUs and the OLTs, which are being

addressed within the COCONUT project are showing promising initial results both on

performance and reduced cost (as per Deliverable 2.2 where BT was a key contributor). If

these initial results can be confirmed during the final year of the project, it could open the

possibility to incorporate them in the NG-PON2 systems if accepted by the Standards

community and incorporated into existing ITU Recommendations. BT foresees that the higher

Power Budgets defined in G.989.2 of 35dB for which there is no current transceiver technical

solution without resort to optical amplification, are a clear target for the COCONUT coherent

technologies.



Page: 15 of 38

During the third year of the COCONUT Project BT will identify those specific technologies

that are suitable to be presented in FSAN towards the NG-PON2 activities and will make the

contributions targeting the FSAN meeting in October 2015.

On the other hand, pending the results of the studies of the final year, and as it has always

been one of the objectives, BT will promote the COCONUT results within the Standards

bodies so its concept and technologies can be a candidate for a future generation of PON

systems. BT would also work towards promoting the COCONUT concepts among the wider

research and commercial communities in the access space.

3.2.2. ERICSSON

At Ericsson, we strive to connect everyone, wherever they may be. By being connected,

people can take part in the emerging global collaboration that is the Networked Society – a

society in which every person and every industry is empowered to reach their full potential.

Our services, software and infrastructure – especially in mobility, broadband and the cloud –

are enabling the communications industry and other sectors to do better business, increase

efficiency, improve their users’ experience and capture new opportunities.

The COCONUT architecture and technical solution are to be exploited for mobile broadband

and the cloud to some extent. Mobile broadband comes with the introduction of small cells,

Cloud by enabling high capacity optical links. We will discuss the exploitation plans for

mobile broadband.

Mobile broadband

Radio networks are evolving towards the deployment of small cells. Depending on the area to

cover and the capacity needs one or another deployment solution can be chosen. Ericsson

considers five key scenarios that would cover the need of a small cell deployment. In all these

five scenarios, COCONUT proposes two main solutions (see figure below): A) CPRI

transport (fronthaul), B) packet/Ethernet transport (backhaul).

Figure 5. COCONUT solutions for two different application scenarios: a) mobile fronthaul where the traffic to

transport is CPRI; b) mobile backhaul, where the traffic to transport is packet or Ethernet.



Page: 16 of 38

In scenario A, CPRI, we would exploit the 2.5G- 10G WTTU COCONUT solution since

CPRI is a high-bandwidth demanding digital interface. For the second case, B, the 1G WTTU

COCONUT solution would be good enough.

Scenario 1: City street/square This considers an outdoor deployment of small cells. In this scenario it is very important the

visual pollution, so small cells will have to be integrated with other urban elements, for

example, light poles, building facades, advertisement posts, etc. The figure below shows what

could be the Ericsson product portfolio solutions for such a deployment and where

COCONUT could be of benefit.

Figure 6. Ericsson product portfolio options for city street/square showing where and which COCONUT solution could apply. RBS: radio base station, mRRU: micro remote radio units.Source: Ericsson,

heterogeneous network handbook.

Café/restaurant Café and restaurant comprises any indoor deployment where there is a high concentration of

users. In these venues the outdoors-in coverage is very poor because of the high wall

penetration loss and would benefit of a small cell deployment. The figure below identifies

where the COCONUT solution could be applied.

could apply. Source: Ericsson, heterogeneous network handbook.

Transport for train station/mall This corresponds to an indoor deployment where the concentration of users is high but they

occupy a larger surface than a café or restaurant. Also users are more mobile than the previous

scenario. In these type of buildings the key challenge is to be able to reuse physical locations,

cabling, ducts, etc. Below we show a possible deployment strategy using Ericsson products

and also when the COCONUT solution would apply.

Stadium

Stadiums comprise both indoor and outdoor deployments where there is a higher

concentration of users in a limited area compared to the restaurant/ café solution. Also the

traffic characteristics here are different than a public hotspot. The uplink is heavy loaded as

compared to downlink.

apply. Source: Ericsson, heterogeneous network handbook.

Office enterprise solution This scenario considers small, medium and large enterprises, hotels and high-rise buildings,

all indoors. As in any indoor deployment, outdoor-in coverage is challenging because a brick-

based building has a penetration loss between 10-30 dB which results in poor data rates, thus

poor quality of service. Below we show how this scenario could benefit from a small cell

deployment and where it would make sense to use COCONUT technology.

apply. Source: Ericsson, heterogeneous network handbook.

Special case, Ericsson RDS (radio dot system)

The Ericsson Radio Dot System, RDS, is a breakthrough solution to indoor mobile coverage

and capacity demands, to effectively connect indoor users to the whole mobile eco-system.

The Ericsson Radio Dot System is targeting larger office enterprise buildings, commercial,

hospitality and residential buildings with similar requirements as office enterprise. The RDS

solution comprises CPRI transmission between the indoor radio unit and the digital unit and

there we could exploit the COCONUT solution A.



Page: 21 of 38

Figure 11. Ericsson RDS solution architecture and COCONUT network opportunities. IRU: indoor radio unit, DU: digital unit.

The COCONUT wavelength plan supports up to 256 optical channels in a single fibre. This

gives us 128 bidirectional CPRI links. This implies that we can cover 128 indoor radio units

(IRUs). That means a single COCONUT-PON is able to connect some 8x128 =1024 RDS

radio heads! While any legacy PON technology (GPON, XGPON, NGPON2) will be limited

by the splitting ratio (32, 64, 128).

Calculated radio capacity in a CPRI link using COCONUT technology

Finally, with a simple calculation we would like to highlight the benefits of using the

COCONUT technology in COCONUT solution A as presented above.

Let us define some initial considerations:

Line rate 10Gbit/s CPRI per direction

320 MHz radio capacity per wavelength channel (using 16 radio signals)

Max # of lambdas to use =256 for 0dBm transmitted power per wavelength channel

COCONUT channel spacing 12.5 GHz

Using the premises above, the total radio capacity of COCONUT network is:

320 MHz *256 C- lambdas=81920 MHz

In order to achieve the same radio capacity when using the standardized ITU-T grid we need

to go up to 50 GHz channel spacing and use the full S+C+L bands, which is not feasible due

to the need for compatibility with legacy deployments.

3.2.3. OPTRONICS

OPTRONICS has significant expertise in the deployment and operation of optical networks

and is currently leading two pilot programs in Greece offering FTTH services. During the first

two years of the project’s lifetime, OPTRONICS has gained significant knowledge on the

novel coherent technologies of COCONUT.



Page: 22 of 38

From the beginning of the project OPTRONICS identified COCONUT solution as a

commercial opportunity. OPTRONICS exploitation plan is to deploy and assess COCONUT

in a real field trial, as a follow-up of the laboratory tests performed by the project partners.

To achieve this goal, OPTRONICS spent effort to disseminate the concept of the project as

well its results to the incumbent and the alternative operators in Greece. The main objective of

these activities was to get the approval from them to pursue the possibility to deploy

COCONUT system in a pilot program.

OTE (incumbent operator in Greece) had been initially contacted during the 1st year

workshop in Athens. The key directors of OTE’s Research and Development department,

were informed about the concept of COCONUT and its capabilities. OPTRONICS received a

positive feedback and followed up with more targeted activities.

During the 2nd year of the project OPTRONICS continued to pursue the opportunity to

deploy COCONUT solution in Greece. Although the project solutions are in an early

prototype stage, OPTRONICS took the initiative and made a provisional agreement (LOI)

with OTE to deploy COCONUT solution as a pilot program in the test bed in Rhodes

Marinas. The Marina includes offices, commercial premises and private berths. The current

architecture is a PON system that offers broadband services to the users (boats) through

optical fiber. OTE has expressed its interest to seek upgrading schemes, such as the

COCONUT setup. A pilot program is agreed to take place after the completion of the project

and based on the availability of the terminal equipment. Being based on foreground of the

project COCONUT, the above pilot will be regulated by the guidelines of the Consortium

Agreement.

The interest of both OTE and Rhodes Marina is presented by means of signed letters in the

Annex I of this document.

Moreover, Optronics sees a business potential in the transceivers currently developed by UPC

and is considering the possibility to develop them further them in the Greek and international

market.

3.2.4. PROMAX

The work carried out during the second year of COCONUT’s project has demonstrated the

overall feasibility and high competitiveness of PROMAX’s “High Resolution Optical

Spectrum Analyzer” (HR-OSA) in the European market. Cutting-edge instruments coming

from vendors such as APEX, EXFO, JDSU, AGILENT and ARAGON PHOTONICS, have

been studied in order to develop a cost effective solutions.

Regardless of COCONUT’s success and exploitation in any European optical network, the

HR-OSA will be introduced in the market, since it is compatible with other current

technologies.

Therefore, PROMAX will perform the following actions, which constitute the exploitation

plan:

First, it will be analysed the patentability of HR-OSA’s design. If potential patentable idea is

identified, its convenience, cost and international extension will be studied.



Page: 23 of 38

Next, the manufacturing cost to mass-produce the equipment is going to be calculated.

Although COCONUT’s proposal already includes costs of optical components available in

the market, the final prototype (April’15) will allow a deeper analysis of real costs.

Besides, further developments are going to be identified in order to expand both commercial

and industrial potentials of the HR-OSA. Since the target market of the HR-OSA is not

expected to be very large, it is necessary to study possible applications such as:

HR-OSA as a laboratory instrumentation and/or handheld equipment for field

applications (Telco and Spectrography markets),

tunable laser for spectroscopy in biomedical applications, Telco (field equipment or

equipment for OLTs) or OCT (optical coherent tomography)

balanced optical receivers for Telco applications

Technical and commercial information of the equipment’s specifications will be drawn. The

concept portable field measurement equipment is shown in the image below.

Finally, it will be presented in exhibitions and forums (ECOC and NFOEC 2016), and

introduced to potential customers.

It is expected to be launched as a product offering during the third quarter of 2016.

3.2.5. 35L

During the COCONUT project, 35L has evaluated some of their devices as low-cost emitters

for coherent access networks. Some other devices will be evaluated during the last year of the

project by the partners. Finally, the most promising devices will be tested during the final

experiments.

If COCONUT devices provide superior performances compared to commercial ones, 35L will

be able to provide an industrial path with the adequate supply chain. These agreements will

depend on the considered volumes, and on internal aspects.

The detailed exploitation plan will strongly depend on the impact of the project, both in terms

of volumes and standardization impact.

In parallel to these industrialization aspects, 35L will also exploit the results of COCONUT

for other applications. In any case, 35L would be able to provide a follow-up of the project, at

least on the device delivery aspects.

More generally, 35L supporters (e.g. Alcatel-Lucent) are involved in standardization and on

system delivery, also for access networks. The evolution of these networks combines an

increase of the bit-rate and of the number of wavelengths, while keeping quite stable optical



Page: 24 of 38

budgets. Within COCONUT, 35L evaluates a large increase of the wavelengths together with

an increase of the optical budget, while keeping a stable bit-rate. The increase of the optical

budget is a very interesting feature, since it allows for an extension of the reach and of the

splitting ratio, on condition that the cost and complexity of the proposed approach remains

reasonable compared to the existing technologies. In this perspective, the outcome of

COCONUT will provide guidance to the company for the future evolution of access

networks.

3.3. Exploitation plans per academic partner

3.3.1. SSA

Knowledge Transfer (KT) activities are at the core of the Scuola Superiore Sant’Anna’s

mission. The Scuola Superiore Sant'Anna has a specific KT Office, which has a significant

experience in KT activities and can rely on numerous important collaborations with

companies and public research institutions. Various spin-off companies, employing a total of

more than 180 people, have stemmed from the Scuola Superiore Sant'Anna’s laboratories.

Some of these companies are commercializing patents owned by the Scuola Superiore

Sant'Anna.

Through the activities of the KT Office, the Scuola Superiore Sant'Anna is committed to fully

exploit public research results and supporting the competitiveness of Italian companies. The

Scuola Superiore Sant'Anna helped found the Network for the Exploitation of Research

(www.netval.it) and the Association of Incubators (www.pnicube.it). It is also a member of

the European Network of Knowledge Transfer Offices “Proton” (www.protoneurope.org) and

founded the “Club of Spin-off Companies”.

Based on this experience, SSA has confidently filed a patent, now extended at international

level, on a new type of polarization-independent coherent receiver. As an academic partner,

SSA will mostly aim at exploiting that patent in cooperation with the KT Office. The KT

Office will offer assistance in the assessment of the patent, patent assignment offers, and

granting of exclusive and non-exclusive licenses for the industrial realization of technologies

(until 2012, about 20% of the patents had been assigned or licensed to Italian and foreign

companies). To this aim, a key role will be played by the final integration experiments, to be

carried out on the Pisa fibres, which, if successful, will strongly enhance the visibility of the

COCONUT proposed solutions and increase the possibility of commercialization.

3.3.2. AIT

In the following paragraph we identify the potentially exploitable areas of the research carried

out by AIT within COCONUT. It is noted that AIT (as a non for profit research and

educational institute) is not obliged to submit a detailed exploitation plan.

The main area of research for AIT is related with the development of the COCONUT MAC in

FPGA boards following the specifications defined in WP5. Beyond the needs of the project,

the goal is to develop a protocol emulation platform in FPGA, on top of which AIT will be

able to develop and test different access network protocols and resource allocation techniques.

The experimentation platform is expected to strengthen AIT’s development and testing

capabilities in the specific field, increasing the collaboration potentials with other partners and

the industry sector, leading potentially to new funding opportunities.



Page: 25 of 38

A second area of exploitable research for AIT is related with the techno-economic and energy

consumption studies. The studies performed within COCONUT task 2.2 in conjunction with

the development work in WP3, enriches AIT’s knowhow with respect to the cost and power

consumption of the new coherent technologies for access. AIT exploits its knowhow in

network deployment and cost evaluation studies through consultancy services offered to

operators and the public sector. A major study has offered a few years ago to one of the

largest operators in Greece, while a related study is currently performed in collaboration with

the incumbent operator of Greece. A deployment and cost evaluation study is agreed to be

offered to a large municipality, while discussions are planned also with other public sector

groups.

Finally, it is noted that the full potentials for the exploitation of the COCONUT research

outcomes will be explored primarily after the completion of the WP5 (T5.4) activities and

following the successful testing outcomes in the final test-bed.

3.3.3. UPC

Implementation plans UPC will develop in WP6 susbsystems that are engineered as prototypes able to be adopted

for production by COCONUT partners or future clients; specifically for example:

- a wavelength-manageable low cost laser unit, with non-preselected statistical

wavelength and limited tuning for coherent systems.

- a fast, high resolution and low cost optical spectrum analyzer with udWDM spectrum

monitoring, control and management functions, in development with Promax

- a low cost coherent ONU using DPSK modulation and full duplex real time operation

integrated with the new statistical spectrum manager.

UPC will closely work with partners to assemble the COCONUT demonstration test-bed in

practical conditions, in terms of simplicity, cost, operation, consumption, environmental

tolerances and scalability. The demonstrations will have strong disseminations to maximize

the project visibility and impact in the European industry. If convenient, UPC will consider

the possibility of funding a start-up to commercialize COCONUT subproducts.

On the other hand, UPC is performing theoretical and experimental tests to validate the

compatibility of COCONUT with previous PON generations coexisting in the same ODN.

This will lead to some guidelines for a possible contribution to standardization bodies by the

representative partners.

4. STANDARDISATION EFFORTS

4.1. Current Situation – Year 1

The COCONUT approach covers solutions for the next generation optical access. This

indicates the relevance of fora and standardization groups that deal with the definition of the

next generation PON such as FSAN, IEEE and ITU-T. IEEE 802.3 finalized the 802.3av

10Gbps EPON specification in Sept 2009 and are currently studying the possibility to start a

new project on a NG-EPON towards higher capacities in the last mile. ITU-T's next

generation standard following on from G-PON is the G.987 for 10G-PON known as XG-

PON.



Page: 26 of 38

In search for a more flexible and scalable solution, the FSAN Group and ITU-T Q2/SG15 are

working on a future fibre access generation (termed NG-PON2). Although FSAN is not a

standards definition organisation, their output is submitted to ITU-T Question 2 in the Study

Group 15 to facilitate the development of global PON standards. The first result was the

description of the drivers and requirements that any candidate PON system needed to meet.

There were a number of candidate proposals that were discussed being the most intensively

investigated the following approaches:

- WDM/TDMA scheme by stacking XG-PON systems (10G per wavelength) with

tuneable ONUs

- General WDM-PONs with tuneable or colourless ONUs.

- Single-carrier 40Gbit/s TDMA-PON

- SCM/OFDMA-PONs with direct detection

- OCDMA with electrical or optical correlation coding.

- Ultra-Dense Wavelength Division Multiplexed (UDWDM) PON networks with

coherent receivers

The main proposals for NG-PON2 achieve different levels of performance and meet a number

of requirements, but not all at the same time, which can be of interest in a wide range of

application scenarios, once the technological hurdles are solved.

In early 2012 the operators in FSAN decided to select TWDM with OOK modulation as the

primary solution for NGPON2. DWDM-PON (ptp via DWDM over a PON ODN) was also

accepted as an optional overlay.

The NGPON2 physical layer (PMD) definition was in its final stage at ITU-T and it was

initially consented in December 2013 (G.989.2). “Recommendation ITU-T G.989.2 specifies

the physical media dependent (PMD) layer requirements for a passive optical network system

with a nominal aggregate capacity of 40 Gbit/s in the downstream direction and 10Gbit/s in

the upstream direction, hereinafter referred to as NG-PON2. NG-PON2 is a flexible optical

fibre access network capable of supporting the bandwidth requirements of mobile backhaul,

business and residential services. Furthermore, this recommendation describes optional

configurations to extend beyond this nominal capacity as the G.989 series of standards allows

for multiple upstream and downstream line rates.

NG-PON2 wavelength plan is defined to enable the coexistence through wavelength overlay

with legacy PON systems (see [ITU G.989.1]). The transmission convergence (TC) layer is

based on Recommendation ITU-T G.987.3, with unique modifications for NG-PON2 captured

in Recommendation ITU-T G.989.3. The ONU management and control interface (OMCI)

specifications are described in Recommendation ITU-T G.988 for NG-PON2 extensions.

This recommendation specifies the characteristics of hybrid time and wavelength multiplexed

channels, hereinafter referred to as TWDM PON. The characteristics of, optional, tuneable

point-to-point wavelength overlay channels are also described, hereinafter referred to as PtP

WDM PON.

The TWDM PON described in this Recommendation represents a further development from

the systems described in the ITU-T G.984 and G.987 series. To the greatest extent possible,

this Recommendation retains the requirements of ITU-T G.984.1 and G.987.1 to ensure

maximal reuse of existing technology and compatibility with deployed optical access systems

and optical fibre infrastructure.” (from the summary of recommendation ITU-T G.989.2).

Nonetheless, COCONUT is not targeting an alternative to NGPON2 but rather aspires to

influence the definition of NGPON3.



Page: 27 of 38

4.2. Current Situation – Year 2

Currently, the standardization activities of the NG-PON2 system are defined in the

Recommendation ITU-T G.989 series and the status is as follows:

Recommendation ITU-T G.989 : Definitions and conventions

Recommendation ITU-T G.989.1: General requirements

Recommendation ITU-T G.989.2: Physical media dependent (PMD) layer

specification (Consented in December 2013 and approved in December 2014 after all

the Last Call Comments were finally resolved).

Recommendation ITU-T G.989.3: Transmission convergence (TC) layer specification

(draft in progress)

o Based on G.987.3, with wavelength control and 10G upstream added

o Target for consent is July 2015

Recommendation ITU-T G.9082 9 (ex G.multi) = Wavelength control layer

o Meant as a general framework for TWDM-systems, of which G.989 is one

o Consented in December 2014

Recommendation ITU-T G.984.5 Am2= Wavelength coexistence

o Consented April 2014

Recommendation ITU-T G.988 = ONU management and control interface

o Standard in force, can be easily reused for TWDM

o An Amendment to include specific elements for NG-PON2 will be started in

2015

An Amendment to G.989.2 has already started and it is foreseen that after the consent of an

initial recommendation for the TC-Layer (G.989.3) and Amendment will also be started.

4.3. Course of Action

4.3.1. 1st Year – Planning

When a suitable solution can be identified in the COCONUT activities, it can be proposed and

discussed within the FSAN Group where BT currently holds the position of co-chair of the

NGPON Task Group.

Once the solution has been discussed and agreed within the FSAN Group, the next step would

be to bring it to the ITU-T for standardisation.

The innovations that the work in COCONUT could bring about, would be applied either to

enhance certain features of the NG-PON2 solution currently being defined in FSAN/ITU or

for a future system (NG-PON3).

4.3.2. 2nd Year – Planning

The 2nd year planning included a contribution to FSAN on the ONU activation times when

using non-calibrated transmitters. However this effort fell through as explained in the above

Section 3.2.1.

Potentially it was also envisaged to bring some of the COCONUT results on the PMD Layer

to the FSAN activities. However, non-definitive results and continual activities within the



Page: 28 of 38

COCONUT Project led to the decision of delaying such contributions until these activities

would be finalised and a clearer picture obtained to take to FSAN.

4.3.3. 3rd Year - Planning

Specifically, BT will identify those specific technologies developed in COCONUT that are

susceptible of being useful in an enhanced NG-PON2 targeting high power budget classes

over ODNs that are based on Optical Power Splitters.

From Table 1/G.989.2 “ODN Optical Path Loss Classes (ODN Classes)” there are 4 classes

defined: Class N1 (29dB), N2 (31dB), E1 (33dB), and E2 (35dB)

Class N1 Class N2 Class E1 Class E2

Minimum optical path loss 14 dB 16 dB 18 dB 20 dB

Maximum optical path loss 29 dB 31 dB 33 dB 35dB

Maximum differential optical path loss 15 dB

Table 1: illustration of ODN Classes in G.989.2

There is currently no technical transceiver solution for classes higher than N1 without using

optical amplification.

The coherent technologies developed in COCONUT may offer a solution to realise such

classes. This includes both the TWDM-PON system and the PtP WDM PON system over

such ODNs based on optical power splitters.

BT plans to prepare a contribution on the COCONUT achievements and specific proposals,

which will be shared with the FSAN Group towards October 2015. BT will coordinate with

relevant partners in COCONUT to prepare this contribution.

BT considers that there is no more scope to contribute to the Standards efforts towards the

TC-Layer (i.e. G.989.3)

Finally, and as has already been mentioned in different occasions, BT will promote the

COCONUT achievements within the Standards bodies in any future study towards a future

PON system activity.

Ericsson is present in two groups of the Broadband Forum (BBF), the fiber access network

working group (FAN), and the operations and network management working group (OAM).

Within the FAN group we are monitoring the working texts (WT): WT- 280, WT-301 and

WT-352. Together with another unit at Ericsson we will revise what parts of the COCONUT

could be applicable to an already existing working text or a future one. Thus, whenever

relevant, COCONUT results will be presented there. Below there is a summary of the relevant

working texts as per last release.

WT-352: The purpose of this working text is to specify a protocol that is executed between

the OLT Channel Terminations and, based on the architecture and functional descriptions

outlined in ITU-T Recommendation G.989.3, enables wavelength channel management

within an NG-PON2 system.



Page: 29 of 38

WT-280: Taking a similar approach to TR-101 and its TR-156 derivative, the purpose of this

document is to specify the requirements for deploying GPON and XGPON1 in the context of

a TR-178 architecture.

As an insight, the TR-178 document presents a set of architectures for a broadband multi-

service network, addressing typical infrastructures, topologies and deployment scenarios, and

specifies associated nodal requirements. These include copper and fibre access architectures

to support business and residential, fixed and mobile, wholesale and retail markets. TR-178

specifies multiservice capabilities beyond the layer 2 based architecture of TR-101 and the

associated TR-156, which specifies the requirements for deploying GPON within a TR-101

architecture.

WT-205: The purpose of this Working Text is to provide the technology-specific management

model for GPON and XG-PON1. The Broadband Forum has specified in TR-156 the use of

GPON or XG-PON1 as the access technology in an Access Node that is part of the TR-101

Ethernet aggregation architecture. TR-141 specifies the management model for a TR-101

Access Node where the access technology is assumed to be DSL. TR-141 does not specify

the management model for DSL and points to such a model in TR-242; it is primarily about

the management of Ethernet and higher functionality. TR-156 introduces some additional

management requirements that impact the management model in TR-141 and so an issue 2 is

being developed to incorporate the necessary changes. TR-141i2 will be largely agnostic to

the underlying access technology apart from pointers to the management models for the

access technology.

WT-312: The purpose of this Working Text is to capture the management requirements of the

Service Providers to enable appropriate specification of the management models and

operations at the NMS-EMS interface.

The Broadband Forum has produced Technical Reports that specify the functionality of

Access Nodes where the access technology is DSL, in TR-101, and where the access

technology is GPON, in TR-156. Management models have been produced, TR-141and TR-

169 for the Ethernet Management aspects of TR-101 Access Nodes and work is in the

progress to extend them for GPON Access Nodes in an up issue of TR-141 and in WT-

205.There is also work proceeding in the TMF on GPON Management. There is also

management capability for ONUs/ONTs detailed in the OMCI of G.988.

It is not clear what of this abundance of management capabilities is actually required by

Service Providers and in particular what management models and operations should be

available at the interface between a Service Provider’s NMS and the EMS that manages the

Access Node and associated optical line management equipment.

WT-318: The architecture and requirements for FttDP are the subject of WT-301. Although

there are similarities of FttDP with other types of concatenated fibre and copper access

systems, e.g. FttCab, GPON ONUs there are also some very different aspects, e.g. Reverse

Power Feeding, small node size, new copper technology (G.fast), low power consumption,

etc. There are also some functions in an FttDP node that do not exist in other systems. These

differences impact the management requirements for the FttDP node. This Working Text

addresses these impacts; it specifies the management architecture and requirements and the

management models for the component parts of the FttDP architecture.

WT-311: With the fast growth of FTTx, rapid deployment and effective maintenance of a new

passive fiber network (i.e. an Optical Distribution Network, ODN) have become major



Page: 30 of 38

challenges for operators. Service provisioning and maintenance of ODN have been inefficient

and inaccurate with the following major flaws:

a. Massive number of fibers identified manually with paper labels

b. Work orders delivered in hard copy

c. Manual fiber connections not verified accurately with a manual check.

d. Port resources are updated by manual input with low efficiency and inaccuracy.

This reliance on paper records and manual actions leads to inefficiency and errors. The

purpose of the Fiber infrastructure management systems (FIMS) is to remove the tendency for

errors and increase efficiency by providing the means to reduce the manual actions involved

in service provisioning and maintenance, and automate the recording of data and verification

of correct manual actions.

Ericsson’s position: In general, the BBF work concentrate on the already standardized

technologies: GPON and XGPON1, only WT-352 is targeting NGPON2. Results from WP5

might be applicable to WT-352, WT-205, WT-312, and WT-318. Results from WP2 could be

applicable to WT-280, but it is yet to be seen. Evaluation of where COCONUT could make an

impact is under study and it will be considered during the year.

COCONUT compatibility with legacy PON systems

One important aspect in a future PON system are the types of Optical Distribution Networks

(ODN) it can use , as well as the co-existence with legacy PON systems such as G-PON, XG-

PON and the recently standardized NG-PON2.

The need for co-existence comes from the operational requirement of upgrading individual

customers without impacting the services of the other customers on the same ODN. Error!

Reference source not found. shows a co-existence scenario where the ODN architecture is

based on splitting technologies and where a Coexistence Element (CE) should be used to

allow the concurrence of the different PON systems.

Figure 12: Co-existence scenario between COCONUT and legacy PON systems.



Page: 31 of 38

Considering this aspect, it will be important to define some guidelines, considering the studies

done by COCONUT partners about udWDM and coherent detection technologies

(COCONUT specs), co-existence and migration scenarios for:

1. UPC will support COCONUT partners as BT contributing to FSAN and ITU in the

process for standardization of a new Recommendation NG-PON3; further studies will

allow to define the requirements of the CE (bandpass bandwidth, adjacent channel

isolation (IA), non-adjacent channel isolation (INA), and minimum guard bands) to

allow co-existence with legacy PONs.

2. A suitable definition of the CE element and its parameters will allow a better

dimensioning of the network considering that the COCONUT channels are more

robust to interference caused by other PON systems and, in the opposite case, the

interference caused by COCONUT over other PON systems can be insignificant in the

case of PSK or FSK. This will lead to narrowing down the guard bands to a fraction

nm, and will allow allocating more udWDM channels as it was explained in

deliverable D2.3.

3. Having a reference for the specifications of CE element and the minimum guard bands

that complement the specifications presented in the standard ITU-T G.984.5 to give

guidelines to vendors and operators in the fabrication, design and implementation of

udWDM PON as COCONUT. These results will be validated and presented in the

COCONUT demo and field trial, and in next international congresses, especially to

potential future industrial takers of the udWDM-PON technology.

regarding the new developments on radio-over-fibre for the full fiberized Ericsson

DOT solution. In the presentation the COCONUT project was introduced and

regarded as a candidate solution for small cell backhaul due to the lambda flexibility

of the solution, and the ultra-dense grid we are targeting.
