摘要
鉴于波分复用(WDM)技术已成为光纤通信的发展方向,本文综述了双向交错传输技术.由于相邻信道之间的相位失匹配,它是抑制四波混频的有效手段;采用适当的放大技术可以抑制瑞利背向散射;另外介绍了偏振位交错复用传输技术,它们对于扩大通信容量很有意义.
Abstract
The wave division multiplexing (WDM) technology has become the current trend of fiber communications. The interleaved bidirectional transmission technology is summarized, that offers an effective means for FWM suppression due to violation of phase matching between adjacent counterpropagating signals. Rayleigh backscatter can be suppressed with proper amplification technology, and the polarization-bit-interleaved multiplexing is introduced.
