Optical fibre is the foundation of the future and is clearly paving the way for progress in all aspects of communications, which now reach far beyond the quad-play spectrum into exciting emerging technologies like VR, AR, smart cars, remote medicine and quantum computing. So as the industry gathers at landmark events such as the Fibre To The Home Conference Europe and OFC on the West Coast, it is fitting that this publication is expanding and increasing its frequency to o er more to our information- hungry readership. Going forward, Optical Connections will be published quarterly and have increased distribution at key industry gatherings throughout the year. Similarly our sister website and e-newsletter will also be carrying more news – simply because, as the industry takes an upward swing, there is so much more happening for the team to cover. A quick look at the current events in Marseille and Los Angeles, respectively. The FTTH Conference, the largest FTTH-related event in the world, is an all- exclusive 3-day event, combining workshops, conference sessions, exhibition and demonstrations. Over the past dozen years, it has become THE place of exchange between di erent stakeholders involved in fibre: policymakers, regulators, operators, vendors, investors, analysts, media and more. The word from our exclusive interviews with D-G Erzsebet Fitori and President Ronan Kelly (pages 15 and 21) is that FTTH markets are booming and that there has never been a better time to get involved with this technology. Meanwhile, In Los Angeles, OFC 2017 is addressing a broader agenda: optical communications and networking technologies, enabling 5G, IoT, virtual reality and artificial intelligence, to name a few hot themes from the conference program and show floor. Global leaders and business professionals have the opportunity to network with the expected 13,000 attendees from more than 65 countries; visit the exhibition with its 600-plus companies; and learn from more than 1,150 technical presentations. This year’s conference program features a dynamic plenary lineup including global leaders from Google, Inc., Eindhoven University of Technology and King’s College London. So in this issue and on our associated website and newsletters you will find insight and technical information that will not only give you greater perspective on the developments you encounter at the events, they will help you with the inevitable critical decisions you have to make in 2017.

Industry partners commit to NFV interoperability testing initiative
THE ORIGINAL PUSH-PULL CONNECTOR
Optical communications giants Cisco, Ericsson, Huawei and Nokia have signed a Memorandum of Understanding to create the Network Functions Virtualization Interoperability Testing Initiative (NFV-ITI), which is designed to help communication service providers to address the challenges related to NFV deployment and Cloud transformation within multi-vendor network environments. The partners stated, “deployment and integration of virtual network functions within today’s multi-vendor environments can introduce new interoperability challenges. To address these challenges, NFV-ITI members will cooperatively support the interoperability of NFV elements in specific customer situations to accelerate the commercial implementations, and to reduce the time-to- market for new applications and services.” All existing NFV interoperability related
testing activities have been triggered by different needs of the industry, including the European Telecommunications Standards Institute NFV Testing WG, OPNFV testing projects, Network Vendor Interoperability Testing, and the New IP Agency interoperability testing. Complementing all the existing NFV interoperability testing activities in the industry, NFV-ITI will focus on testing interoperability configurations of commercial NFV solutions actually used in the communication service providers’ networks. It will recommend generic principles, including interoperability test cases, test criteria, processes, methods, guidelines, templates, and testing tools, and will also apply best practices from all existing interoperability testing activities in the industry, such as the NVIOT forum efforts. NFV-ITI will be well aligned with the ETSI NFV Industry Specification Group and the OPNFV project.

Unconventional laser could improve telecommunications
the UC San Diego Jacobs School of Engineering, who led the research, said “The popular VCSEL may one day be replaced by what we’re calling the ‘BICSEL’ — bound state in the continuum surface- emitting laser, which could lead to smaller devices that consume less power.” The team’s next step is to make BIC lasers that are electrically powered by mounting the membrane on a conductive substrate and, although the device’s current efficiency is about 20 per cent, they believe this can be engineered to reach much higher values.

MATTHEW PEACH INVESTMENT
in future-proof infrastructure
is ALWAYS VALUABLE
E rzsébet Fitori was ten years’ experience in regulatory a airs and public policy, including four years as Director at the European Competitive Telecommunications Association, she was previously Head of Regulatory A airs at Telenor Hungary in Budapest. She is passionate about the continent’s need for optical fibre and ensuring that the Council completes its mission to appointed as Director General of the FTTH Council Europe in mid-2016 and started the job on 1 September. An academic and a lawyer with more than accelerate the availability of fibre-based, ultra-high-speed access networks for the benefit of consumers and businesses. “I believe that fibre is the foundation of the future and it’s paving the ground for progress; in many ways, that progressive agenda is what drew me to this role in the FTTH Council Europe. What is not yet widely enough recognised, I believe, is that in the near future, fibre will be foundational for almost all of our high capacity networks, whether they are fixed or wireless gigabit-networks.” She cites the imminent arrival of 5G as a driver that will depend on really deep fibre deployment to enable the capabilities that generally distinguish it from 4G. Fibre will also be necessary to enable next generations of autonomous driving systems, the Internet of Things, a digitised European industry and how healthcare will be carried out in the future. “This not only because of the high speeds that are possible with fibre but also because of the low latency of such networks,” Fitori explains. “For example, the connected car, which is emerging in

all developed markets, will most likely not require very high bandwidth – but some critical functions will need to have no delay. There will obviously not be a fibre line connected to the car, but its wireless connection there is will need to have millisecond latency.” EUROPEAN AGREEMENT Fitori has close contacts with the increasingly fibre-focused European Commission (the Council’s headquarters is just a few hundred meters away). There is an ongoing revision of the telecoms framework of the European Union; the latest legislative proposal for which was published in September 2016. “I think it likely that there will be policy changes, “ she says. “One of the most important changes put forward by the EC is the ubiquitous availability and take-up of very high capacity networks; it has been proposed to become a regulatory requirement, which was not policy previously.” The FTTH Council Europe believes that this policy change will be a positive step towards getting Europe to become a global digital leader again. The other main issue a ecting FTTH development is the setting of new gigabit connectivity targets for Europe in the Gigabit Society Communication of the European Commission. The Council is very supportive of these connectivity objectives, believing that the whole vision and direction are the right priorities.
across Europe. For example, the Nordics and Portugal and Spain are extremely advanced in their FTTH/B penetration, with, for instance, a rate of 35% in Sweden, 19% in Portugal and 14% in Spain at end- September 2015. Other countries such as the UK and Germany have coverage that is still pretty low (around 1% penetration rate). Fitori comments, “I am hopeful that soon there will be big shifts in markets such as Germany and the UK but, as it stands, Europe is still behind Asia and the UAE. This makes it very significant how we develop policy on new deployment of fibre or the continuation of the old copper networks. Europe’s global competitors are so far ahead with fibre that Europe is becoming a museum for copper networks if we do not step up the mark now.” So does Fitori feel that the market and regulatory reforms are su cient pressures to e ect the changes she wants? “If we want to nurture digital innovation in Europe, our infrastructure must be best-in-class. We can see really strong outcomes when there is commitment from governments and regulators to actively promote and stimulate the private market towards FTTH/B investments. This is precisely what European regulation should do so that all European citizens and businesses can have very high capacity connectivity and be part of a Gigabit Society.” “It’s important for private investors to get more involved in this market and that policy is clear on promoting future- proof fibre investments. There is often an investment case for non-urban and more remote areas and we should not leave anyone behind. For example, in France in non-commercial areas fibre networks are deployed as a PPP. She concludes, “investment in future- proof infrastructure is always valuable and this type of development should not be shaken up by political changes, such as Brexit, that much. To me it’s very factual. Connectivity is politically neutral.”

ROY RUBENSTEIN TELCOS
Bon voyage: Coriant, Facebook and Telecom Infra Project are developing the Voyager (pictured here), a converged transponder and IP/MPLS white box solution.
Telcos
look anew at network design
D evelopments in telecom services are causing service providers to rethink how they architect their networks. So claims Uwe Fischer, CTO at Coriant. Fischer cites how the growth of high- capacity video and 4G mobile services are placing challenging capacity requirements on the network. There are also low latency requirements for emerging applications such as driverless cars that need specific networking functions placed close to the user.
“If it was a pure transport box the input rate would equal the output rate but because it is a packet box, you can take advantage of layer 2 over-subscription,” says Niall Robinson, vice president, global business development at Adva. Adva Optical Networking is backing Voyager because it does not have a packet-optical platform in its product portfolio. “We are enabling ourselves to play in the packet-optical space with a self-contained box,” says Robinson. Coriant does have its own packet-optical platforms. Its interest is in Voyager’s role as a router.“ To support the telecom use cases, it is very much about putting software on top of the hardware and that is exactly our contribution,” said Fischer.

Transformation of design and operation of next-gen networks is underway as vendors and service providers
“A lot of the classical telcos are challenged by this new network
environment and it is driving people to rethink the way they want to build their networks,” says Fischer. It has led some telecom operators to explore how the Internet content providers build their networks, with their use of open-source software and disaggregated white-box platforms. Some operators are even collaborating with the Internet content players. One example is Facebook working with ten operators as part of the Telecom Infra Project (TIP). TIP has over 300 members including systems vendors, component makers and contract manufacturers. TIP has created seven working group projects across three network segments: access, backhaul, and core and management. One of the TIP projects, part of backhaul, is the Open Optical Packet Transport, which has unveiled its first platform: a white-box packet-optical platform dubbed Voyager. VOYAGER Voyager is a one-rack-unit box designed by Facebook, with the specification made available to TIP members. Voyager is based on Facebook’s Wedge top-of-rack switch designed for the data centre and which is now being made by several contract manufacturers. Each Wedge switch can be customised based on the operating system used and the applications loaded. The goal is to adopt a similar approach for Voyager. Companies backing Voyager include Acacia Communications, Broadcom and
Coriant points out that dedicated IP routers with its layer 4 and above
capabilities will still be used in the network but the combination of a router platform like Voyager coupled with higher-layer functionality that is moving from specialised platforms to servers running software- defined networking and virtualised network functions, operators now have an alternative architectural approach. “It is how we see the packet network will be done in future with people moving away from classical IP routers and using such packet-forwarding switches, ” says Fischer. SIGNIFICANCE Adva’s Robinson is confident Voyager will be a cost-competitive platform and points to the open-source software community developing its feature set. Robinson, a 25-year industry veteran, describes TIP as one of the most ambitious and creative projects he has been involved in. “ It is less around the design of the box,” says Robinson. “It is the shaking up of the ecosystem, that is what TIP is about.” Fischer believes TIP is an example of a growing momentum among operators for change. Voyager, for example, may not be adopted everywhere and may start with greenfield deployments but the alternative of continuing to evolve existing networking systems only leads to more complexity. “I think the time has come where continuing the way we have done in the past will most likely not lead us to success,” says Fischer.
strive to cope with soaring demands.
Lumentum, which are involved in the platform’s hardware design. Snaproute is delivering the software inside the box while first units are being made by the contract manufacturer, Celestica. Two systems vendors, Coriant and Adva Optical Networking, are also involved. Adva will provide a sales channel for Voyager and is interfacing it to its network management system. The system vendor will also provide services and software support. Coriant is bringing its switching and routing expertise to Voyager as well as its dense WDM open line system. Voyager is already being trialled by operators and is expected to ship from April. SPECIFICATION At the core of Voyager is the Broadcom StrataXGS Tomahawk, a 3.2-terabit switch chip that is also used in the Wedge switch. The Tomahawk features 128 x 25 Gbit/s serialiser-deserialiser (SerDes) to enable 32 x 100-gigabit ports and supports layer 2 switching and layer 3 routing. Voyager uses 12, 100 Gigabit Ethernet client-side pluggable interfaces and two Acacia AC -400 5x7-inch modules for a total of 800 gigabits of line-side capacity.
