Huawei to supply ROADMs for China Telecom's intelligent optical backbone network

Huawei says that it has achieved sole vendor status to supply systems for China Telecom's ROADM Network Project, which will see an upgrade of the service provider's backbone fiber-optic network in the middle and lower reaches of the Yangtze River. The deployment is part of China Telecom's CTNET2025 network transformation strategy.

Huawei says that it has achieved sole vendor status to supply systems for China Telecom's ROADM Network Project, which will see an upgrade of the service provider's backbone fiber-optic network in the middle and lower reaches of the Yangtze River. The deployment is part of China Telecom's CTNET2025 network transformation strategy.

The project will see Huawei supply colorless and directionless ROADMs for deployment in 21 sites in Hubei, Jiangxi, Anhui, Jiangsu, Zhejiang, and Shanghai. The area along the Yangtze River through which the enhanced fiber network will pass is the fastest developing region in China, according to Huawei. The network therefore will be expected to support low-latency, high-performance requirements for data center private lines and financial services customers.

Along these lines, the ROADMs will help improve network security and intelligence, Huawei asserts. The optical transport systems will facilitate the provisioning of advantageous routes to upper-layer service networks, such as routes with one-hop transmission, full mesh interconnection, optimal path and latency, and rapid recovery from failures.

According to Wei Leping, deputy director, Science & Technology Committee, Ministry of Industry & Information Technology and Director, Science & Technology Committee, China Telecom, the ROADM deployment is a step toward creation of an all-optical network in the region. Such a network would feature fully optical transport, switch, and access capabilities, with ROADMs and optical crossconnects deployed at the switching layer.
