中文摘要：
随着偏振复用正交相移键控（PM-QPSK）编码、基于数字信号处理（DSP）的相干接收、前向纠错（FEC）等关键技术的突破,目前100Gb/s光传输设备已发展成熟,相应测试仪表也有多个厂家推出,国内外针对100 Gb/s光传输设备的实验室和现网测试也已规模开展,虽然在性能测试方面存在部分尚未解决的难题,但整体上已为100 Gb/s光传输设备规模商用奠定基础。
英文摘要：
Thanks to the achievements of PM-QPSK coding,coherent receiver technology and Forward Error Correction（FEC）,100Gb/s optical transport equipment has been well developed and is ready for its emerging commercial application.Several vendors already introduced their 100Gb/s testing equipments.Lab and field tests of 100Gb/s transport equipment have also been carried out,both domestically and worldwide.Although some test items of 100Gb/s transport equipment are still under development,this won＇t have any influence on the commercial application of 100Gb/s in the near future.
