摘要
本文从理论上研究了四波混频在多级放大频分复用光通信系统中的特性，提出了一种消除四波混频串扰的新方法，该方法只需适当选择信道间隔，无需增添其它器件，因而更有利于在实际光通信系统当中的应用。
The characteristics of four wave mixing in frequency division multiplexed systems with cascaded amplifiers have been investigated in this paper. A novel technique for four wave mixing cancellation by choosing appropriate channel spacing has been proposed. This method needs no additional devices, and is attractive for application in long haul frequency division multiplexed systems.
