Through the innovative use of emerging coherent optical communication technology and the advancement of microelectronics technology, the new-generation 100Gb/s transport technology offers a high line rate and unprecedented resilience 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 100Gb/s system. China Mobile's considerations, which were based on the trial results, regarding the deployment of 100Gb/s transport systems are introduced, and the requirements of China Mobile for the evolution of 100Gb/s transport systems are summarized.展开更多
