Fujitsu Develops DSP Algorithm for 100G Long-haul Optical Distortion

Researchers at Fujitsu have developed a digital signal processing algorithm to compensate for waveform distortion in long-haul transmission systems operating over several hundred kilometers. The method is aimed at 100 Gbps transmissions, which tend to suffer from waveform distortion caused by nonlinear optical effects over distance. Fujitsu said a key advantage of its new technology is that it does not require signal regenerators. The nonlinear...
