Fujitsu develops world’s first optical-transmission technology to achieve 100 Gbps using 10 Gbps transmission components
Fujitsu today announced the development of the world’s first optical-transmission technology that can achieve 100 Gbps transmission speeds using widely available, conventional components intended for 10 Gbps networking. Fujitsu Laboratories and Fujitsu R&D Center have applied a Discrete Multi-Tone (DMT) modulation/demodulation format using digital signal processing (DSP) to transmit at 100 Gbps per channel using conventional components intended for transmission speeds of 10 Gbps per channel.
Increasing data-transfer rates has typically required new components designed for those higher speeds, for which existing components have not been compatible. Moreover, there is a limit to the speed improvements that can be achieved with transmission methods using the simple modulation and demodulation formats that have been used to date.
Applying this technology to an optical transceiver with four channels would result in a 400 Gbps Ethernet transceiver, which are needed in the next generation of datacenters in order to increase their data transmission speeds and processing capacity to better support cloud services.
Details of this technology are being presented at the Optical Fiber Communication Conference and National Fiber Optic Engineers Conference (OFC/NFOEC 2013), beginning March 17 in Anaheim, California.
