Fujitsu, Nippon Telegraph and Telephone Corporation and NEC Corporation today announced the commencement of joint research and development toward making the world’s top-level, 400Gbps/channel-class digital coherent optical transmissions technology . Bringing together the technological capabilities that have enabled the commercialisation of 100Gbps-class optical transmissions methods, which are becoming more prevalent among the world’s optical networks, the companies will work to further enhance the performance and functionality of the digital coherent optical transmissions method, a key technology in optical transmissions. This enables the possibility of realising the world’s top-level optical networks that combine ultra-high speeds, low energy consumption and flexibility, while also contributing to improvements in optical transmissions technology and the global spread of the research results. This R&D initiative was commissioned and is sponsored by Japan’s Ministry of Internal Affairs and Communications (MIC) as part of the “Research and Development Project for the Ultra-high Speed and Green Photonic Networks” program.
“In 2012 the supply and demand of 100G products began to converge, leading to significant growth in deployments. The demand for network connectivity will only increase. Therefore, the need for 400G solutions that provide even greater bandwidth with the lowest possible power consumption and flexible, adaptive modulation will be critical,” noted industry analyst Dana Cooperson, VP Network Infrastructure, Ovum, Inc. “Fujitsu, NTT and NEC’s collaborative efforts to meet this growing demand illustrate what’s possible when key industry players work together. Carriers, enterprises, governments, and others would be wise to look closely at this solution as they evolve their networks.”
