摘要
为了抑制四波混频(FWM)效应, 根据其产生机理和主要影响因素, 提出了对传统频率等间隔波分复用(WDM)系统的两种改进方案, 一种方案是设计中间大、两头小的信道间隔, 另一种方案是设计不等间隔交叉呈现的信道间隔。分别用OptiSystem软件搭建了7信道WDM系统, 并进行了仿真研究。结果表明两种改进方案均能很好地抑制FWM效应, 且第二种方案比第一种方案效果更好。
Abstract
In order to suppress the four wave mixing (FWM) effect, two improved schemes aiming at traditional wavelength division multiplexing (WDM) systems with equal frequency intervals are proposed according to the formation mechanism and main influence factors of FWM effect. One scheme is to design a channel spacing which is broad in the middle and narrows toward each end. Another scheme is to design the channel spacing with unequal intervals. A seven-channel WDM system is established and simulated with OptiSystem. The two schemes can suppress the FWM effect and the second one is better than the first one.
