On the Mitigation of Polarization Dependency of Distributed Raman Amplifier Gain by Transmission Fiber PMD
收藏 引用
光学学报 2003年 第S1期23卷 635-636页
作者: Toshiyuki TOKURA takashi mizuochi Information Technology R & D Center Mitsubishi Electric Corporation 5-1-1 Ofuna Kamakura Kanagawa 247-8501 JapanInformation Technology R & D Center Mitsubishi Electric Corporation 5-1-1 Ofuna Kamakura Kanagawa 247-8501 Japan
We show theoretically and experimentally that Raman PDG can be formulated as a function of the pump light DOP and the transmission fiber PMD. Raman PDG is sufficiently reduced thanks to the inevitable fiber PMD.

A Study of Electronic Equalization Scheme Enabling Optically Pre-Filtered 1 bit/s/Hz DWDM Transmission
收藏 引用
光学学报 2003年 第S1期23卷 558-559页
作者: Hirofumi Totsuka takashi Sugihara takashi mizuochi Hiroshi Kubo Hitoyuki Tagami Kuniaki Motoshima Mitsubishi Electric Corporation Information Technology R&D Center 5-1-1 Ofuna Kamakura Kanagawa Japan
A numerical simulation shows that by using electronic equalizers 1 bit/s/Hz spectral efficiency can be attained with the same signal quality as a 0.8 bit/s/Hz system. Waveform distortion due to optical band-limiting i... 详细信息
