| 摘 要： | 为了抑制光纤中4波混频(FWM)效应引起的信道间非线性串扰,采用了实验的方法,对高非线性光纤中FWM效应的影响进行了研究,测量了产生FWM的效率与信道间隔以及信号强度的关系,比较了等信道间隔和非等信道间隔情况下FWM效应的影响。结果表明,FWM的效率随着信道间隔的增加而减小,随信号光功率的增加而线性增加。等信道间隔情况下,FWM效应对中间信道的影响最大,与非等信道间隔相比,FWM效应引入了1.5dB的功率代价。这些结果对有效抑制光纤中的FWM串扰是有帮助的。

Experimentally study of four-wave mixing influence in WDM optical networks |
| |
| Abstract: | The impact of four-wave mixing crosstalk on WDM systems in high nonlinear fiber is studied experimentally. Results show that the generated wave efficiency decrease with increasing channel spacing and increase with input signal power. The influence of FWM on signal is compared when the channels are arranged equal and unequal. It is shown that 1.5dB larger penalty is introduced in the case of equal channel spacing than in unequal channel spacing. |
