Fujitsu Shrinks by 70% Distortion-Compensation Circuit for Fiber-Optic Transmissions over 100 Gbps

Tokyo, Kawasaki and Beijing, Sept 22, 2010 - (JCN Newswire) - Fujitsu Limited, Fujitsu Laboratories Limited, and Fujitsu Research and Development Center Co., Ltd. of China today jointly announced that they have developed a digital signal processing algorithm that compensates for waveform distortion in signals sent over hundreds of kilometers of fiber-optic lines, as part of a long-haul transmission system, and that they have also reduced the size of the required circuitry by approximately 70%. This advance will usher in long-haul fiber-optic transmission systems transmitting data at a rate of more than 100 Gbps per wavelength at a lower cost than conventional 10 Gbps systems in the networks that tie together carrier trunk lines and major datacenters. It had been thought that the practical deployment of such systems would be difficult to achieve even in 10 years, but Fujitsu's new technology is now expected to make it possible within five years.
