OPTICAL NETWORK CAPACITY BOOST FOR NEW PROJECT
A research project is aiming to expand the capacity of optical metro and core networks. Funded by Germany’s Federal Ministry of Education and Research and led by optical transport vendor, ADVA, the OptiCON project will explore technologies that could enable fibre infrastructure to carry 10 times more throughput than it does currently. Its goals include leveraging
unused optical spectrum, new fibre and novel transmission schemes. Te three-year project involves the Fraunhofer Heinrich Hertz Institute (HHI), highstreet technologies, the Technical University of Munich and VPIphotonics. Annika Dochhan, OptiCON
project lead explained: ‘Tis project couldn’t be more vital. With optical transmission approaching the Shannon Limit and continual increases in per-channel speeds coming to an end, we’re looking at disruptive ways to expand network capacity. By using untapped spectrum, we can maximise the value of dense wavelength division multiplexing (DWDM) networks and tackle soaring data demand from cloud, video and mobile.’ Te research project, said
Dochhan, is about engineering the next-generation of transport networks and empowering operators to keep pace with exponential traffic growth. She said: ‘It builds on everything we’ve achieved with our FSP 3000 open line system (OLS) and TeraFlex terminal technology, which ensures lowest cost per bit for any network. We’re taking fibre transmission to the next level.’ DWDM transport has historically
been limited to the C-and L-bands of the optical spectrum. By working to overcome longstanding technical and economic hurdles, OptiCON hopes to enable operators to exploit more of the available fibre bandwidth and carry more bits per second. Tis will be achieved via technical innovations, including advanced amplifiers and improved fibre, plus new techniques for monitoring and control. Ronald Freund, head of photonic
networks and systems at Fraunhofer HHI, said: ‘Our work in OptiCON is focused on the physical layer and developing optical telemetry. Tis is crucial to enabling the fine-grained data signal adjustments needed for full-capacity optimisation.’
ETISALAT AND HUAWEI TRIAL OPTICAL CROSS-CONNECT Based on the optical backplane
UAE service provider Etisalat has partnered with Huawei to trial compact all-optical cross- connect (OXC) for the transport industry. Te aim is to help deliver technology to simplify optical architecture for future networks. OXC devices like the trialled
OptiXtrans series OSN 9800 P32C are used by carriers to switch high-speed optical signals in a network, such as an optical mesh network, to improve scalability, shorten time to market for new services, and reduce costs. Te trial promotes use of the OXC solution. Tis particular device is a large-capacity OXC design that can be used in the backbone or aggregation layer. Liquid crystal on silicon
technology is used to enable the optical switcåhing capacity to Pb/s level for high compact 16-degree grooming capability. Te companies said the device integration is nine times that of the traditional reconfigurable optical add- drop multiplexer (ROADM) solution, which can save 80 per cent of room space.

ring that spans major business districts, including multiple enterprise buildings and, initially, three core data centres. Tis infrastructure will connect key landing stations in Marseille, providing access to strategic sub-sea cables connecting to the Middle East, Far East and East Africa. Enterprise and wholesale customers can expect to get direct access to localised transport and IP services in Marseille and route diversity options to maximise network availability and minimise latency. An additional 90 data centres will also be
Tier-one service provider, CenturyLink has built new metro networks in Madrid and Marseille, and is set to connect an additional 90 data centres to its network in six of its core markets. In Madrid the provider built a metro network
footprint of 40 route miles, creating a ring that spans major business districts, including the city centre, financial areas, and Silicon Alley. Te infrastructure will connect key enterprise buildings and an initial five core data centres, to provide fast, secure networking solutions. Te expansion in Marseille is designed to
enhance the company’s ability to deliver local and international connectivity services. CenturyLink built a dense metro fibre footprint, creating a

connected to the firm’s network in the UK and Ireland, Benelux, DACH, Nordics, Southern Europe and Eastern Europe. Tese are expected to be completed by the
middle of next year. Richard Warley (pictured), regional president
EMEA, CenturyLink, said: ‘Our new fibre expansions in Europe take CenturyLink’s network and technology services deeper and closer to our customers. Tis puts us where we need to be to meet their growing and evolving digital business needs, as well as enhance their customer experience with new technology solutions. Tis regional investment reflects CenturyLink’s global focus to continue enhancing our significant fibre network for fuelling innovation.’
technology, it was demonstrated that the OXC product can print more than 1,000 optical fibres on an A4 size backplane. Tis means that the service provisioning time can be shortened from 30 to three minutes. Te digital optical layer adopts Huawei’s optical label technology to support end-to- end visibility of wavelength-level network status. Optical network troubleshooting time is shortened. Esmaeel Al Hammadi,
senior vice president, network development at Etisalat, said: ‘Tis solution with Huawei will enhance development of the infrastructure and simplify the network, reducing service provisioning time, and improving efficiency in operations and maintenance to provide an optimal network experience for customers.’

ROSWELL RECEIVES DARK FIBRE OPTION
American fibre infrastructure provider, FiberLight has completed a deployment of dark fibre in Roswell, Georgia. Tis project was undertaken in
partnership with value-added re-seller, SereneIT. It connects the city to an Atlanta-area data centre operated by Ascent, allowing optimised performance for the area and support for its sophisticated applications to meet user demand for real-time access. Te city was enabled with a dark fibre
network ring, with 400G of capacity deployed to the Ascent data centre. Dark fibre allows organisations to own, build, expand, and control networks faster than building fibre routes from scratch, and helps to fulfil the need for continuous bandwidth growth. Maurice Pryce, IT director for the City
of Roswell stated: ‘Tis dark fibre network solution enables us to have greater control to provision more reliable services and create an always-on environment for our residents. Connecting to Ascent’s datacentre gives us ample room to expand our services and capabilities into the future.’
