摘要

由于海底应用环境复杂

海底光缆会受到海水的压力、冲击和暗流等作用

具有随机性的偏振模色散（PMD）成为系统极限传输的限制因素。文章对横向应力、弯曲等外界因素对PMD的影响进行了理论分析

根据海底光缆的实际工作情况

模拟4×2.5 Gbit/s系统取3 dB的功率冗余度

进行了PMD仿真

得出系统正常工作时PMD系数不超过1.8 ps/km的结论。为避免PMD补偿

当弯曲半径为0.3 m时

要求横向应力不得大于8.9 N/m。

Abstract

As submarine cables applied in usually complicated environment are subject to water pressure

impact and subterranean flow

the resulted stochastic Polarization Mode Dispersion（PMD） has become a limiting factor for the system extreme transmission.In this paper

the effects of such external factors as lateral stress and bending on PMD are theoretically analyzed and simulation of the 4×2.5 Gbit/s communication system is performed in accordance with the actual work conditions of the cable

taking 3 dB as the power redundancy.Simulation results show that when the communication system works normally

the PMD coefficient does not exceed 1.8 ps/km.In order to avoid PMD compensation

the lateral stress is not to be greater than 8.9 N/m when the bending radius is 0.3 m.
