DRZ和CSRZ的4O G DWDM系统的性能测试

摘要

It is the increasing capacity and rate requirement that improve the development of 40 GB/s DWDM Tb/s system, such as Broadband, IPTV, Triple Play, P2P, etc. Firstly, this paper introduces the current situation of N×40Gb/s system. Secondly it introduces the scheme of key technologies and modulation format (ODB, CSRZ, DRZ, DPSK, DQPSK) of NX40Gb/s system. And then it proposes optical interface parameters requirement of 40 Gb/s. Finally, it presents simulation result and test research of N×40 Gb/s system.%介绍光波分复用N×40 Gbps系统的发展现状；其次,阐述光波分复用N×40 Gbps系统的关键技术及调制码型技术( ODB、CSRZ、DRZ、DPSK、DQPSK),提出了40 Gbps WDM系统光接口参数的要求；然后,采用加入合适的可调式光衰减器(VOA)方法,进行眼图等性能测试；最后,通过40G系统仿真结果及具体试验,40GWDM系统可以满足商业应用需求.
