能有效提升不规则跨段链路下的系统传输性能。

Abstract

The techniques of transmission performance optimization for high-speed coherent optical detection based 100Gbit/s PDM-QPSK systems is studied under the irregular fiber span configuration scenario.The analytical calculation model for the optimal link configurations is obtained under the irregular fiber span scenario.Numerical simulations are carried out for verification.Simulation results show that the optimal configuration scheme outperforms the conventional full span loss compensation scheme with 1.3dB Qfactor improvement.This optimal configuration method can be effectively applied for current link design and online performance optimizations in 100Gbit/s PDM-QPSK systems

to improve their transmission performance under the irregular span scenarios.
