Fiber enclosures are used in buried, underwater and aerial applications

Typically enclosures with patch panels are used in aerial application for convenience

Where splicing is possible, enclosures can contain splice trays

Splice Enclosures: Aerial, Terrestrial and Submarine


Cabinets and Pedestals

There are a lot of different cabinets and pedestals options for PON architectures

Fibers can be managed in these devices to improve ease of use supporting rapid deployments and overall organization

All while securing the fibers and equipment in a secure and weather proof enclosure

Fiber Splitters

Splitters are a main component of GPON optical distribution networks

An optical splitter is a passive device

Two basic types

• Fused Biconical Taper (FBT)

• Planar Lightwave Circuit (PLC)

Depending on the light direction, they either split incoming light or combine it

Common available split ratios:

• 1:2, 1:4, 1:8, 1:16, 1:32, 1:64

• 2:X are required for Type B protection

There are two basic types splicers

Mechanical .03 dB

Fusion .02dB

Fusion Splices

The most advanced fusion splices like the Fujikura 62S (shown) are not only fast but are extremely accurate

Splicers

Testers

Visual Fault Locator (VFL)

Used to trace and detect broken or cracked fiber

Optical Power OPM

Although a single port OPM can be used, you really need a pass thru tester for GPON

EXFO OPM pictured here is specifically designed for PON and can give accurate measurement of the upstream burst levels

Optical Time Domain Reflectometer (OTDR)

Measures the attenuation and back reflection properties of the three wavelengths over a fiber for a PON architecture

1

7


Cleaners

Best Practices

Keep dust caps on all unplugged connectors

Never touch fiber ends with your fingers

Use correct cleaning tools

Invest in a cleaning kit

Fiber cleaner or cassettes

Wipes

Bulkhead and Connection cleaner

A fiber scope is also nice to have

Safety first - always ensure the power is off before using a fiber scope

Splitters

The biggest loss contributors in the ODN are the Splitters

This has a direct result on the design considerations and number of ONTs supported at varying distance

General rule of 3db for every 1 by 2 splitter although the actual loss will always be greater

Compounded when splices and associated connections are factored in

Distance Attenuation – Signal Loss

Attenuation is loss of energy in a light signal as it travels through the fiber

Directly proportional to fiber length

There are two main causes of intrinsic attenuation

Absorption

Scattering

2

2


Attenuation – Bending

Extrinsic – external source

Macrobending: large-scale distortion due to bend or kink

Microbending: smaller-scale distortion due to things such as pressure on the fiber• Examples:

• Fiber frozen in ice • Caught in a door or cover lid

Both affect the angle of incidence in the fiber and result in signal attenuation

May not be readily apparent

Marco Bending

Micro Bending

Other Loss Contributors

Splices/Connectors - typical attenuations:• -0.1 dB per fiber fusion splice

• -0.5 dB per connector

Contamination

Damage to end face

Additional security range: • 3 dBm for further fiber aging

• To account for temperature extremes

• Additional splices

FEC can recover up to 3 dB to the loss budget

RF Return Overview

Service providers desire two-way video capabilities

Enables introduction of interactive programming guides

Allows for IPPV, VOD and other interactive services

Increases ARPU (Average Revenue Per User) for video services

FSAN did not establish a RF Return specification for GPON

Presents a challenge for FTTH vendors and service providers

RFOG (RF over Glass) put together by the SCTE

Calix has a RFOG solution

There are three technical options for addressing RF Return

1) Sampling of the RF spectrum

2) Conversion of the QAM (or QPSK) to IP

3) Optical return path

Ranging

What is Ranging

Process for computing the logical distance between the OLT and ONT and then compensating for that distance to allow multiple ONU transmissions without collisions

GPON must compensate for varying distance from 0~20 km

All ranging is initiated by the OLT

OLT computes the round trip delay

This delay information is used to create the “equalization delay”

ONT incorporates this delay into the time between the grant and actual transmission

All ONTs appear equidistant as if they were 20 km from the OLT

Active Ethernet Design budgets

Small form factor 10GE transport, GPON / Active Ethernet

When 700GX ONTs are operating in Active Ethernet mode, the system's optical transmitters may require attenuation to avoid over-saturating the optical receivers. The following chart details the relationship between distance (from the SFP to the ONT) and the appropriate E-Series SFP module to use.

For example, an optical link that is up to 20 km long can use a 40 km rated SFP as long as a 10 dB attenuator is inserted in the link.

** Calix recommends using the 60 km rated SFP only for links longer than 20 km. This eliminates the need for a 15 dB attenuator and simplifies attenuator inventory

Business and mobile services

Symmetrical services; often more than 1 Gbps

Common infrastructure

Different service types on each wavelength

Dedicated wavelength (pt-to-pt) to larger enterprises (included in NG-PON2 standard)

G.Fast MDU solutions

Requires greater backhaul speeds

Support for gigabit and multi-gigabit services

SFU residential

Increasing bandwidth demand greater than 2.5 GPON by 2020

Greater acceptance of Open Access networks is drives support for multiple service providers on a common infrastructure

RF Video


The two standards are converging, but key differences remain

10G EPON does not offer 2.5 Gbps in the upstream

10G EPON offers 1.25 or 10 Gbps in the upstream. 1.25 is too low for a next generation standard, offering no improvement over current EPON standard

10G on the upstream is aimed at businesses or large fiber-to-the-basement MDUs – not cost effective for single family residences or small MDUs

10G EPON with 1.25G upstream cannot be on the same optical distribution network as 2.5 GPON (both utilize 1310 nm wavelength)

Both versions of 10G GPON (2.5G and 10G upstream both use 1270 nm) can be used on a 2.5 GPON ODN

GPON supports a higher number of splits than EPON• GPON can split as high as 128; EPON is limited to 32-way splits

Optical link budgets

29 dB is the primary budget for both XGS-PON and NG-PON2

Existing outside plant GPON splitters

Need wide operating splitters (U Grade) supporting 1260nm through 1650nm

Optical budgets synched between GPON and next gen

Add loss from coexistence elements and higher attenuation at 1270 nm (for XGS-PON)• CEx loss of 0.8 dB for 2.5 GPON path,

1-1.5 dB for Next Gen wavelengths

28 dB 2.5 PON ODN can be overlaid by a 29 dB XGS-PON

Wavelength multiplexer loss already included in NG-PON2 budget

Next gen PON deployment guidelines

Any GigaFamily product can coexist with any 10G ITU standard

700GE and 836GE ONTs can coexist with any 10G ITU standard

700GX and 760GX ONTs coexist with units that started shipping in 2012

Determining whether a Calix 700GX ONT supports 10G overlay

Calix will provide a compatibility list based on CLEI codes

CLEI codes are observable in CMS

Calix customers’ existing networks are ready for NG-PON2

overlay with ONTs deployed beginning in 2012

Applications

Next gen PON will be used first for serving businesses and MDUs, SFUs to follow

NG-PON2 is the destination network

Tunable ONU optics costs will delay commercial availability of NG-PON2

XGS-PON’s fixed wavelength solution is a great transition technology

RF video customers can use XGS-PON; NG-PON2 requires some work arounds

Calix is rolling out next gen PON starting in NOW!

E7-2 E7-20 E3 sealed form factor (ROLT)
