摘要

介绍了烽火通信研制的国内首套、具有完全知识产权的80×40 Gb it/s密集波分复用（DWDM）系统

该系统采用了低成本的非归零（NRZ）码

开发了分布拉曼放大、超强前向纠错（FEC）、子速率复用等多项技术

并在G.652光纤上进行了10×80 km的无电再生中继传输实验。实验结果表明

经过800 km传输后

光通道代价<2 dB

连续观察60 h无误码。

Abstract

This paper introduced the 80×40 Gbit/s dense wavelength dvision multiplexing（DWDM） system developed by FiberHome. It is first system in China and FiberHome holds all intelligence property of it. The system employs distributed Raman amplification

superFEC and tributary transparent multiplex （TTM） technologies. The transmission experiment of 80×40 Gbit/s DWDM system using NRZ code over 800 km G.652 fiber line was carried out .The test results show that the optical path penalty is less than 2 dB and the system runs error free for continuous 60 hours after 800 km transmission.
