Through the in- novative use of emerging coherent optical communication technology and the advance- ment of microelectronics technology, the new-generation 100Gb/s transport technology offers a high line rate and unprecedented re- silience to optical transmission impairments. This paper overviews the bandwidth demands of China Mobile driven by the upcoming roll- out of Time Division-Long Term Evolution （TD-LTE） and presents the 100Gb/s trials at China Mobile that were used to verify the performance of a lOOGb/s system. China Mo- bile＇s considerations, which were based on the trial results, regarding the deployment of lOOGb/s transport systems are introduced, and the requirements of China Mobile for the evo- lution of lOOGb/s transport systems are sum- marized.展开更多
