100G部署优势及商用案例(本期优秀论文)

Advantages of 100G deployment and a commercial case

100G技术是被业界普遍看好的下一代高速传输技术。随着100G标准化工作的完成,偏振复用正交相移键控(PDM-QPSK)、相干接收技术及前向纠错(FEC)等关键技术的突破,100G技术已经发展成熟,国内运营商均处于测试和试商用阶段。基于巨量的业务需求和长期的技术积累,江苏XX运营商正在建设的省干100G波分系统即为国内首条商用100G OTN系统。

100G technology is generally bullish by the industry on the next generation of high-speed transmis sion technology. With the completion of 100G standardization and the key technology breakthrough of polar ization division multiplexed QPSK （PDM-QPSK）, coherent reception technology, forward error correction （FEC）, etcetera, 100G technology has maturely developed and domestic operators are all in test and trial com mercial stage. Based on the huge demands and long-term technology accumulation, the 100G OTN provincial backbone bein built bv Jiansu xx operator is the first domestic 100G OTN system for commercial use.
