Huawei confirmed a contract to build an 80×40G WDM national backbone network for China Mobile. 
Upon its completion, the network wavelength capacity will be upgraded from 10G to 40G, which will enable China Mobile to offer more ultra-broadband services and bring an enriched service experience to its subscribers. Financial terms were not disclosed.
In June 2010, China Mobile issued a call for bids for its Shanghai-Nanjing-Hangzhou 40G national backbone network project. This project is the first trial of an OTN (optical transport network) national backbone in China and it covers core areas in the Yangtze River delta, including Shanghai, Nanjing, and Hangzhou.
