1、 What is optical wavelength division multiplexing technology? WDM (wavelengt

OTN (optical transport network) is a transmission network based on wavelength d

OTN（光传送网，OpticalTransportNetwork），是以波分复用技术为基础、在光层组织网络的传送网，是下一代的骨干传送网。简单来概括就是以波分

第一：光纤通信的优点 传输距离远：光纤连接距离可达120km； 传输速度快：光纤接入能够提供

一．什么是光波分复用技术？ 光波分复用（WDM，Wavelength Division Multiplexing）技术是在一根光纤上能同时传送多波长光信号的
