摘要
为不断提升电网的数字化程度,满足各类大容量电力通信业务的传输需求,持续推进电力骨干通信网演进,需建设具备高速率、多业务、大带宽的通信传输网络。文章阐述了400G光传输网(optical transport network,OTN)的技术发展情况,从编码调制方式、新型光纤系统、相干接收和数字信号处理技术、软判决前向纠错技术等方面介绍了400G光传输系统的关键技术,并以4×100G OTN在750 kV伊库线超长站距的应用案例探索单波400G OTN在超长站距电力通信的应用可能。
Driven by the imperative to enhance power grid digitization,accommodate diverse high-capacity communication services,and advance backbone network evolution,constructing high-speed,multi-service,largebandwidth optical transmission networks becomes essential.This article overviews the technological progression of 400G Optical Transport Network(OTN)systems.Key technologies are analyzed,focusing on encoding modulation schemes,new optical fiber systems,coherent reception with digital signal processing and soft-decision forward error correction.A case study of ultra-long-span power communication is investigated using 4×100G OTN on the 750 kV Yili-Kuche transmission line,demonstrating the feasibility of single-wavelength 400G OTN deployment in challenging grid scenarios.
