Industry partnership 56GBaud R&D platform
Anritsu, Coherent Solutions, Oclaro and Teledyne LeCroy partnered at ECOC 2015 to implement the industry’s first commercially available research and development platform for testing single-carrier coherent optical communication systems at 56GBaud and above. Matthew Peach interviewed Alessandro Messina, Anritsu’s Wireline Marketing & Business Development Director.
also working on defining the standard for 400GE. Technical challenges; client requirements Current and future trends are driving research and development towards investigation and simulation of new transmission techniques, which must allow speeds up to 400Gbps and reaches from a few centimeters (in data centers) to many kilometers, supporting all related applications. To achieve high speed and long reach simultaneously, engineers and researchers need reliable, precise, high quality test and measurement solutions, to simulate different more and more complex setups, and investigate the cost/performance ratio of each technology, carefully analysing the related signal
integrity to overcome network problems. All the new transmission techniques under evaluation have some common characteristics, including: multiple parallel transmission channels, speeds ranging from 14Gbps to 56Gbps, synchronisation and equalisation requirements and signal modulation. measurement solutions to support new high-end R&D activities. The company’s MP1800A Signal Quality Analyser is designed for optimal research and development performance in terms of signal quality and testing functions of high-speed interconnects and networks. This is because the complexity of the next-to- come transmission setups is forcing engineers to consider Anritsu’s solution Anritsu has long been developing test and
New technologies, such as Internet of Things (IoT), real- time cloud computing and automotive data communication services, are expected to generate a massive demand of high-speed traffic in the core network, with the additional requirement that speed, together with transmission bandwidth, must stretch from the data center to wherever the end user is located. This means that the efforts to achieve higher speeds involves not only the usual players for geographical networks, but also IT companies specialised in data centre solutions and consumer electronics. These companies are already working on increasing transmission speed in interconnects, buses, network cards, with protocols such as PCI Express, Thunderbolt and USB. At the same time, the IEEE is

R ecent significant growth in data communications volumes is now developing into an explosion in data volumes, generated by the proliferation of cloud- based services. At the same time, the increasing importance of data centres driving technological trends, in conjunction with the need for operators and carriers to offer faster, next-generation networks, is generating pressure towards deployment of new high-speed links, beyond current client network 100GE technology towards coherent 100G, 200G and 400G for metro and core networks.
