Fujitsu Partners with NTT and NEC to Launch Joint R&D Efforts
By Raju Shanbhag
Recently, Fujitsu Limited joined hands with Nippon Telegraph and Telephone Corporation (NTT (News - Alert)) and NEC Corporation (NEC) to start a joint research and development.
This initiative looks to make the world’s top-level, 400Gbps/channel-class digital coherent optical transmissions technology.
Coherent optical communication is a field which has benefited greatly by advances in digital signal processing (DSP). With DSP-based phase and polarization management techniques, coherent identification becomes dependable and practical.
Enabling compensation of linear impairments including chromatic dispersion and polarization-mode dispersion using digital filters, the complicated field of the received signal is now completely recovered.
The partnership looks to combine the technological features that have facilitated the commercialization of 100Gbps-class optical transmissions methods. These methods are now becoming well known among the world’s optical networks.
The three companies will also work to further improve the performance and functionality of the digital coherent optical transmissions method – an important step as digital coherent optical transmissions method is an important technology in optical transmissions.
“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 (News - Alert), NTT and NEC’s collaborative efforts to meet this growing demand illustrate what’s possible when key industry players work together.”
Recently, the company unveiled the next generation of its NETSMART 1500 software. This considerably eases and quickens Ethernet Service Provisioning, Traffic Engineering and Service Assurance. Advanced route selection of Connection Oriented Ethernet (COE) paths becomes a point-and-click operation because of the new GUI (Graphical User Interface)-driven tools using standardized MEF (News - Alert) (Metro Ethernet Forum) terminology.
This allows operators to install revenue-generating Ethernet services more rapidly than ever.
