KAWASAKI, March 22 – Fujitsu Laboratories Ltd. and Fujitsu R&D Center Co., Ltd. today announced that, to connect multiple datacenters scattered within a metropolitan area with high capacity and at low cost, they have developed a basic architecture for digital-signal processing in optical transceivers transmitting data at 400 gigabits per second over a single wavelength.
Fujitsu have developed new transceiver architecture in which, on the transmitter side, a specially designed reference signal is transmitted, and this is used on the receiving end to effectively compensate for distortion. Fujitsu successfully performed repeaterless transmission tests over a distance of 160 km.
This technology accurately compensates for variations in the characteristics of transceiver components and distortions introduced in the transmission path, making it possible to communicate at 400 Gbps per wavelength using inexpensive optical transceiver components.
This technology can be applied to integrated optical transceiver components using silicon photonics, a technology expected to reduce costs and contribute to building next-generation distributed computing platforms that will support 5G mobile networking and diverse IoT services. Details of this technology are being presented at the Optical Fiber Communication Conference and Exhibition (OFC) 2016, opening March 20 in Anaheim, California.
