been adopted by the IEEE for 50 Gb/s per lane Ethernet signalling and is expected to become the building block for future multiple-100G rate interconnects. “Finisar is pleased to demonstrate industry break-through and market- leading products to our customers at the largest show focused on Optical Communications,” said Todd Swanson, EVP of Global Sales & Marketing at Finisar. The CFP8 module is a versatile new form factor, offering the highest date rate commercially available today. The Finisar CFP8 family includes an FR8 version supporting 2km reaches and an LR8 version for 10km reaches, both operating over single mode fibre. The module is ideal for router-to-router and router-to- transport client interfaces. HYBRID VIRTUALISATION Today’s networks are a complex array of customized hardware, making it costly and time consuming for CSPs to maintain. Launching new services often requires significant operational investments in planning and provisioning hardware and infrastructure. The adoption of virtualized infrastructure, where key network functions run as software on commercial platforms, eliminates these hurdles. By supporting delay-sensitive services, and offering better security and termination of flows at the network edge, this platform supports a variety of applications including modernized business services, as well as future needs driven by the Internet of Things and 5G. “Carriers need to get everything they can out of their current network assets. “We are giving our customers a cost-effective, future proof and easy- to-implement solution, which they can use now to improve service agility, and for the demands of future IoT and 5G networks on the same open and flexible platform,” said Erez Zelikovitz, VP SDN/ NFV Solutions Global Portfolio at ECI. NETWORK DISAGGREGATION Committed to open solutions and disaggregation, Coriant empowers cloud data centre and network operators with the game-changing Coriant Groove™ G30 Network Disaggregation Platform. Purpose-built for the surging demand for Data Center Interconnect (DCI) cloud, high speed metro, and long haul applications, the Groove G30 can be equipped as a muxponder terminal solution and as an Open Line System (OLS) optical layer solution and features the industry’s highest density and lowest power consumption. The Groove G30 enables the lowest start-up costs and cost-effective scalability. As an open Network Disaggregation Platform (NDP) offering configurations for secure DCI transmission and optical line solutions enabled through open APIs, the Groove G30 ensures rapid introduction and integration.

Data management: Nokia Networks’ robustness centre for core networks

FSP 3000 CloudConnect platform for the hyperscale era,” said Christoph Glingener, CTO and COO, at Adva. “Our TeraFlex technology is taking speed and efficiency to the next level. What our customers now have is the most choice, scale and flexibility available in the industry.” GATHERING CLOUDS As more content and services move to the Cloud, providing high-speed, low- latency connectivity is crucial between data centres and enterprise branch office locations. The proliferation of cloud-based business applications has driven a surge in bandwidth needs and demand for faster speeds at the edge of the network. This has led to the need for simpler and more cost-effective network interface devices (NIDs) supporting 10G rates and beyond. demarcation and optical transport for Ethernet and wavelength services. It is a low-latency, compact and versatile Network Interface Device (NID) providing network demarcation at customer premise sites. It effectively extends the reach of the optical network in support of 10G E-Line or W-Line services. As part of the Nokia Optical Transport portfolio, the 1830 PSD leverages the same optics (SFPs) used within the broader 1830 PSS product family and common network operations being supported by the Network Functions Manager for Transport, formerly the 1350 Optical Management System. It enables a wide range of applications and services including: network or service extension; network interconnection or access, such as LAN or data centre interconnect; and service interworking. 100G – 400G OPTICAL MODULES Finisar has launched multiple new module types, including the 400G CFP8 FR8 and LR8 transceivers, 200G QSFP56 FR4 and LR4 transceivers, and a 100G QSFP28 eSR4 extended reach transceiver. In 2017, the company has also demonstrated its Flexgrid single low profile Wavelength Selective Switch for next generation ROADM subsystems. Nokia’s 1830 Photonic Service Demarcation provides network The MSA-compliant 400G CFP8 transceiver is enabled by 50G pulse amplitude modulation (PAM) technology; PAM4 is a modulation format that has

economics. In short, this means twice the capacity per channel, three times the distance at equivalent capacity, and four times the service density, all at less than half the power – bold claims by the developer. TRANSATLANTIC TERABITS Subsea optical networks are also a critical piece of the global communications infrastructure, enabling cloud-based services to reach users around the world. Given the high complexity and cost of deploying submarine optical systems, subsea operators prefer high- performance, easy-to-use, high-capacity transmission equipment that maximizes their return on investment. Infinera recently announced the completion of a subsea field trial with a major subsea network provider on a trans-Atlantic route. The field trial was conducted with the Infinera XTS-3300 meshponder and demonstrated the potential of 19 terabits per second per fibre pair, delivering the highest spectral efficiency on a major trans-Atlantic route. Andrew Schmitt, Lead Analyst at Cignal AI, said of the development, “While optical vendors have demonstrated experimental approaches to boost subsea fibre capacity, the XTS-3300 is the first commercial platform that can deliver over 19T of capacity on a trans- Atlantic route.” 600GBIT/S FOR DATA CENTRES Adva this year unveiled its next generation high-speed terminal for the FSP 3000 CloudConnect. Specifically developed for hyperscale data centre interconnect applications, Adva’s TeraFlex terminal transports 600Gbit/s of data over a single wavelength, delivering a total duplex capacity of 3.6Tbit/s in a single rack. This represents 50% more density than any competing technology, the company claims. The unprecedented throughput and density of the company’s expanded FSP 3000 CloudConnect platform is critical for ICPs and CNPs that need to scale their DCI networks to meet spiralling data demands. “Our new terminal technology is truly groundbreaking, but today’s launch is much more than this. What we’re announcing here is the evolution of our
