摘要

伴随着传输距离和传输速率的提升

光放和色散管理已成为光纤通信系统中非常重要的影响因素。在40Gbit/s光纤通信系统逐渐替代10Gbit/s系统的过程中

通信系统对非线性抵抗性和色散管理提出了更高的要求。文章通过对3种色散管理方案进行对比

讨论了40Gbit/s光纤通信系统中的不同色散管理方案下的输入光功率对光纤传输系统的Q值、误码率和光信噪比的影响

并且发现中置放大的色散补偿方案具有更好的Q值和信噪比

更适合超长距离光纤通信系统。

Abstract

With the increase of transmission range and rate

optical amplification and dispersion management have become important factors in fiber-optic communication systems.Specifically

in the gradual replacement of 10Gbit/s fiber-optic communication systems by 40Gbit/s systems

still higher requirements are placed on nonlinear resistance and dispersion management by communication systems.In this paper

three dispersion management schemes are compared and the effects of the input optical power in different schemes on the Qvalue

BER and SNR of 40Gbit/s fiber-optic communication systems discussed.It is found that the dispersion compensation scheme with mid-amplification has better Qvalue and SNR and is more suitable for ultra-long fiber-optic communication systems.
