Huawei Technologies announced that it has won a contract from China Mobile towards building an 80x40G WDM (wavelength division multiplexing) national backbone network.

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.

This project is the first trial of an OTN (optical transport network) national backbone network in China and it covers core areas in the Yangtze River delta, including Shanghai, Nanjing, and Hangzhou.

“Huawei’s industry-leading 40G solution and our experience in deploying 40G networks have enabled us to become the leader in the global optical transport industry and the global 40G industry,” said Christian Chua, president, Transport Network Product Line, Huawei. “Our 40G OTN solution will enable China Mobile to meet the growing service demands on its network so that its subscribers can enjoy an unmatched service experience.”

Huawei’s 40G OTN solution incorporates technologies, such as ultra-high 40G bandwidth per wavelength, an ultra-large OTN capacity, and an OTN bandwidth pool, which enables the quick deployment of networks and the flexible and efficient provisioning of services. Huawei’s solution features an ODUk-SNCP protection mechanism that works at the electrical layer to dramatically enhance network reliability.
