Fujitsu Limited (Fujitsu), Nippon Telegraph and Telephone Corporation (NTT) and NEC Corporation (NEC) have announced the commencement of joint research and development toward making the 400Gbps/channel-class digital coherent optical transmissions technology. Bringing together the technological capabilities that have enabled the commercialization 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.
This enables the possibility of realizing 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” programme.
“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,” said Dana Cooperson, Vice-President, Network Infrastructure, Ovum, Inc.
To accommodate the growth in data communications traffic stemming from the spread of the Internet and smartphones in recent years, 100Gbps-class optical transmission methods are starting to become more practical. At the same time, with the arrival of the big data era, along with a surge in the diversity of data due to the spread of machine-to-machine communications, customer expectations with regard to speed and service continue to grow.
