摘　　要：电力通信骨干传输网向100 G光传送网(optical transmission network,OTN)的升级对网络的功率预算、信噪比提出了更高的要求,给超长站距系统的设计带来了挑战。文章基于新一代大有效面积、超低损G.654.E光纤试制了光纤复合架空地线(optical fiber composite overhead ground wire,OPGW)光缆,对光缆关键性能进行了测试,成缆后光纤的平均衰耗小于0.150 dB/km。对于超长跨距100 G OTN系统,其能显著降低信号功率衰耗,提升光信噪比(optical signal noise ratio,OSNR)裕量,从而支持更长的传输距离,也可减少OPGW光缆在受雷击时偏正态(state of polarization,SOP)波动带来的系统误码风险。The upgrade of power communication backbone transmission network to 100 G optical transmission network(OTN)puts forward higher requirements on the power budget and signal-to-noise ratio of the network,which brings challenges to the design of ultra-long span transmission system.This paper introduces a new generation large effective area,ultra-low loss G.654.E fiber,uses it to manufacture the optical fiber composite overhead ground wire(OPGW).The key performance of the optical cable is tested,and the average attenuation of the OPGW is less than 0.150 dB/km.For ultra-long span 100 G OTN systems,it significantly reduces signal power loss and increases the optical signal noise ratio(OSNR)margin,thereby supporting longer transmission distances and reducing the risk of system error caused by state of polarization(SOP)fluctuations in OPGW optical cables when struck by lightning.
