Having recently moved into the role of Sales Director for our EMEA business, I am grateful for this opportunity to introduce myself to many of you for the first time through the medium of our Connected magazine.
I know from speaking to many of you in person that this is both an exciting and challenging time in our industry as we seize the opportunities provided by the ever growing consumer demand for data and cloud based services. As a result, today’s networks need to be built and new standards developed that anticipate this future growth.
In our first article you can read about what FTTH network designers need to consider, right now, in order to build access networks that protect their investment and last well into the future.
At the heart of these networks, increasing use of fiber and migration to higher transmission speeds are some of the challenges we hear about most often. You can read about the impact this has on fiber management on optical
distribution frames in a central office environment and how the use of 24 fiber technology and physical layer management systems can help a smooth migration to 40 and 100 Gigabit Ethernet in the data center.
I also hope you enjoy reading how one of the leading UK higher education establishments, Southampton University successfully took on the challenge of meeting the needs of 23,000 students from 130 countries when they successfully upgraded to a new data center.
Please let us know what topics would be of interest to you in future editions by entering our feedback competition and helping us to stay Connected!

FTTH FOR THIS CENTURYHOW TO BUILD NETWORKS THAT LAST AND SURVIVE FUTURE REQUIREMENTS
The optical fiber network infrastructures installed today will typically experience four generations of transmission systems over the network’s expected lifetime. As recent history has shown, the amount of data traffic these new networks will carry will increase dramatically over their lifetime.
In order to cope with this increase, a completely open spectral transmission window from 1260nm to 1625nm for data transmission and up to 1650nm for network monitoring is necessary in all portions of the optical network, including the access portion of FTTH network deployments.
TODAY’S SITUATIONIn core, metro and long haul fiber networks, attention has traditionally been paid to the deployed network’s long-term reliability. These networks have been built to last for decades, and have had to support, without interruption or failure, increasingly heavy traffic at higher and higher bandwidths.

This was not always the case for the access part of the network as downtime affecting residential customers was historically not the highest priority for network operators. However, times and customer expectations have changed.
Fortunately, as pressure and expectations from both business and residential customers has increased, technology has evolved. In recent years, standards and technologies have opened up a wider portion of the fiber spectrum to assure that expensively deployed access networks have the potential to last into the future.
REQUIREMENTS FOR FUTURE TRANSMISSION SYSTEMSThe new transmission standards that are under discussion allow operators to increase the FTTH networks’ bandwidth capacities and reduce deployment cost by sharing the same fiber with more connected customers or sharing networks with multiple operators.
By using transmission wavelengths from 1260 to 1625 nm, they employ more of the fiber deployed and allow seamless overlays of new services to existing GPON networks.
But, with both a wider spectrum and a less forgiving customer base, comes the need to use components and cable management that supports these more damanding bandwith requirements.
The next generation, NG-PON2, downstream channels will operate in the wavelength band between 1600 nm and 1625 nm.
To future-proof networks, all network components installed today should be specified for use at 1625 nm. Standardization bodies like ITU-T and IEC will pay attention to this in the revisions of the standards for cables and connectors, but network designers need to anticipate these changes now in order to build networks that last.

THE IMPACT OF NETWORK EVOLUTION ON OPTICAL DISTRIBUTION FRAMES
As consumer data demand increases service providers are challenged to meet market demand for high-speed, high-bandwidth broadband services – at cost levels acceptable to the market. Addressing these requirements entails upgrades to both network equipment and network topologies.
Many network elements such as optical distribution frames (ODF) that support service providers’ CAPEX and OPEX models, can help operators to build cost-effective, future-proof networks.
These ODFs should handle (super) high fiber counts, while maintaining ease of installation, supporting strong fiber cable management and providing an open platform to accept emerging technologies.
Deeper deployment of fibers means an ODF could be placed on each interconnection point in the network (trunk + feeder + distribution + last mile). Suitable ODF specifications will be defined by the space available and the function to be performed in that part of the network.

Examining these trends in the network’s evolution, we can conclude the following:
• Connection points are becoming access points for network diagnostics and network upgrades.
• The number of skilled people (e.g., splicing technicians) is decreasing and employment of lower-skilled people is growing.
• Access to specialized tools (e.g. splicing equipment) is becoming more difficult as operators look to minimize CAPEX spending and seek solutions suited to a “plug and play” approach.
• The maintenance aspects of access networks are growing in importance, which can lead to higher OPEX, at a time when operators are trying to minimize OPEX. We see a strong move from “fit and forget” consolidation points towards “flex” points.
The upgrade of existing networks, and the rollout of new networks and services demands careful attention to all a service provider’s assets – including the choice of optical distribution frames for the central office and points of presence.
The best networks are built to be not only reliable, but also flexible, expandable, and most of all, adaptable to whatever changing technology may require.

The ability to migrate a data center infrastructure from 10 to 40 or even 100 Gigabit Ethernet (GbE) can hinge upon knowing the nature and length of the data center backbone. If the overall lenght of the circuit, the connector style (LC, 12 or 24 fiber MPO) or the fiber type (OM2, OM3, OM4, SM, etc.) is unknown, then it is not possible to know if the link can support 40 or 100 GbE. Since this type of information is rarely collected, Physical Layer Management (PLM) systems can provide instantaneous access to detailed information about the length and type of cables deployed so data center managers can migrate their network with confidence.
By having all physical layer cabling, components and their details documented, circuits requiring upgrade can be identified, selectively prioritized and deployed as needed, allowing for a controlled migration. Panel upgrades, for example, could be by module or
blade rather than entire chassis or enclosure. This discrete migration will be more cost-effective than a wholesale forklift upgrade, migrating the most needed paths quicker, and delaying CAPEX investments while avoiding the complexity of a wholesale migration.
With thousands of cables in play, wholesale migration is a daunting and expensive prospect that could delay migration for years.
Without accurate records a discrete migration is slow and difficult involving the manual measurement cable pathways, and trail and error when the new cables are connected. Enterprise industry average statistics show it takes approximately 50-55 minutes just to trace the circuit manually (this is based on a circuit from switch port to panel to station/cabinet).
With greater bandwidth capacity than competing technologies, Fiber-to-the-Home enables new possibilities for a connected world.

PLM systems enable IT managers to understand the physical characteristics of their networks down to the connector and port level. With a PLM system, each physical cable connector has an identity chip that stores information about the connector type, color, cable length, location, and other manufacturer metrics.
A managed patch panel reads the information and forwards it to a database and software management system. By viewing the PLM database, IT managers can determine precisely the length of a cable pathway, how many connections it contains, what type of cable it is and how it will perform. The PLM system measures a variety of metrics, including:
• Media type – the type of cable and connector, such as LC or MPO, 12 or 24 strand fiber cable.
• Wiring pattern – 12 and 24 strand cables won’t have the same wiring patterns, and it’s essential to track the wiring pattern coming out of trunk cable A and know whether it’s compatible going into trunk cable B.
• Performance level – whether it is a 40 or 100 GbE cable, OM3 or OM4. This also provides details about the expected performance of a cable assembly.
• Insertion and cleaning – the number of insertions is used as an indicator of how often a particular fiber should be cleaned – if the fiber has been re-connected four or five times, it’s a good idea to clean it to remove dust or oil.
• Length of cable – the intelligent connectors enable the database to add up all the components on a circuit and see if the circuit exceeds the length budgets for 10, 40, or 100 GbE. Even if the circuit segments are different lengths, it will base the length determination on the media type and expected performance level.
CONCLUSIONWith a PLM system in place, IT managers can determine the most critical network segments that should be upgraded first, where they are, and how long they are. This allows managers to upgrade only the areas of the network that have the greatest need, enabling a gradual migration that brings higher-level service to key segments quickly.
Investing in a PLM system allows network managers to give differential service to their clients, yield revenues for high-speed service more quickly, and efficiently and confidently manage their network each day.

ChallengesTo replace the legacy data center as the University’s primary data center, providing a future-proofed facility capable of supporting 23,000 students.
TE Connectivity SolutionCat 6A copper, MPO fiber trunks, Quick Fit MPO cassettes and FiberGuide
The University of Southampton (UoS) serves 23,000 students from more than 130 countries. With five libraries containing three million books, journals and reports together with a further 50,000 e-books, they rely on a robust data center to store a wealth of intellectual information and huge amounts of data to facilitate the smooth running of the University. The UoS IT Professional Service (iSolutions) team is responsible for designing, building and operating an extensive ICT infrastructure based on a single data center. The new data center was constructed with the help of TE Connectivity and supports all Internet, Voice and WAN connectivity, corporate business systems, staff and student desktop computing resources, the managed learning environment and research computing.

When UoS took the decision to build a new data center, flexibility, longevity and quality were key design requirements for the mission critical educational environment and it turned to TE for assistance. UoS trusted TE to deliver a single, totally integrated data center that would meet the University’s services requirements from day one and offer the modularity of design necessary to nimbly scale up to future needs with minimum effort.
After working with UoS to design the new data center, installation of fiber and category 6A products began. The products chosen are capable of delivering the latest high-speed, bandwidth hungry applications whenever and wherever they are required.
Being 100% pre-terminated, these solutions are designed for quick, easy and reliable operation in data centers with components that are fully compliant with internationally recognized data center standards. In addition, TE’s MPO to LC Quick Fit cassettes were deployed. Again, the plug and play nature of the MPO fiber trunks resulted in a fast installation time and the use of MPO cassettes provided a high density, space saving solution. An additional benefit lies in the precision manufacturing process that guarantees highly reliable but modular equipment that can nimbly scale up to accommodate future expansion. TE added its market-leading FiberGuide product to create clearly defined cable routing paths and keep the cables organized. This approach uses less space and avoids the tangled mess of cables that can potentially restrict airflow and subsequently require more power for cooling purposes.
TE designed the data center so that it is physically separated from the backup facility, reducing the risk of losing data in the event of major incidents such as fire or flood, crucial in a mission-critical organisation where mitigation of risk is essential.
Just five months after the first product shipment, UoS had a state-of-the-art data center, fit for purpose today and in the future
“We have enjoyed a long-standing relationship with TE and our trust in their ability to deliver outstanding support and high quality, scalable products is highlighted by the success of this latest project. We are exceedingly proud of our new data center. It has the power to provide new services quickly and cost-effectively and accommodate future expansion. Quite simply, its excellence reflects our first-class teaching status and ranking in the top 1% of all universities worldwide.”

AGILE INFRASTRUCTURE FOR DATA CENTER MIGRATIONSD

As data centers trend toward higher bandwidth requirements within changing cost structures, operators face an array of challenges in preparing for migration to next-generation electronics. With the skyrocketing increase in the use of smartphones and other mobile devices generating enormous amounts of data traffic, data center operators need to stay ahead of the demand curve.
THE BALANCING ACTData center planning is a continuous balancing act in terms of speed, distance, space and flexibility, with flexibility being the key. Greater flexibility allows easier adjustments as data centers move toward speeds of 40, 100 and even 400 gigabits per second (Gb/s). Server migration is expected to move from predominantly 10 GbE today to primarily 40 GbE (and some 100 GbE) over the next four to five years, with 400 GbE possible within 10 years. Migrations from 10 to 40 to 100 GbE can be accomplished through the installation of low loss 24 fiber multifiber push-on (MPO) trunks.
It is critical to choose optical distribution frames, panels and raceways that also enable seamless migration for electronics with next generation speeds. Multimode optical fiber is prevalent today as it offers the right balance of performance, density and cost. However, today’s data centers may already require singlemode fiber for higher speeds or greater distances. Singlemode fiber optics are increasingly making sense from the
entrance facility to the main distribution area, and from floor to floor in megadata center designs. Therefore, data center designers are asking at what point a transition from multimode to singlemode must be made to achieve the sweet spot between cost and distance. As speeds and/or distances increase, the transmission media may need to change.
There are many considerations when designing the most agile data center network possible. Since the design involves budget concerns and some guesswork, a good plan is to build the highest agility into the physical layer of the network that cost, space and present needs will allow.
te.com | CONNECTED 05.2015 15
A MATTER OF PLANNING
Once the planning is underway for a data center upgrade, operators must consider the following questions:
• How fast must the transmission be?• How far must the signal travel?• How much space is available?• How much is agility worth?
One key is to design a network to handle higher backbone speeds about two years before the servers actually require the capability. With proper agility designed into the backbone, data centers can build infrastructures that can migrate into the foreseeable future.
Figure 1 shows a typical 10/40/100Gb/s migration path using an agile infrastructure that can support predicted change scenarios. Adding agility early can deliver big dividends later, since no one can predict exactly what lies ahead.
DENSITY & POWER CONSUMPTION
The demand for faster speeds is exceeded only by the need for greater energy efficiency. Many data centers already consume enough power to light up a small town. Every time an upgrade to higher data rates becomes necessary, more power is required
Density is the other key to lowering the cost of data center operations as the demand for higher bandwidth and speeds trend up. Every tile of data center floor space has associated cost; therefore, it is critical to support maximum revenue in each rack unit of vertical data center space. High-density frame solutions bring huge benefits by increasing terminations per square foot. Terminating as many connections as possible between network equipment in as little floor space as possible is critical, particularly in multi-tenant data centers

.IT’S A NEW WORLDThe number of people relying on smartphones, wearables, and other network-connected devices that did not exist a few years ago is increasing dramatically every year. This creates massive amounts of data center traffic, forcing data centers to adapt. The result is tremendous growth in data centers and the need for continual migration to the next generation of technology.
Data centers must handle more complex requirements efficiently through solutions that will provide the agility to change and adapt.
The only way to keep data center growth sustainable is to achieve higher data rates cost-effectively, manage the growth and manage the power consumption – a tall order in anyone’s
estimation. It is crucial that your network is agile enough to meet the organization’s architecture and business requirements today and tomorrow while taking the right technical risks that align best with financial objectives.
Data centers are depending on equipment and component manufacturers to help them accomplish these goals by innovating technologies, re-thinking architectures and continuing the development of smooth migration paths to every new generation. Agile infrastructure solutions are the key to smooth data center migrations
