Huawei bags optical network project from China Telecom

Huawei Technologies at MWC 2017Global telecom equipment maker Huawei has bagged a bid from China Telecom for building the Reconfigurable Optical Add/Drop Multiplexer (ROADM) Network Project in the middle and lower reaches of the Yangtze River.

The Chinese technology company in a statement said the first intelligent ROADM WDM backbone network in China will be marking the beginning of China Telecom’s optical transport network evolving towards the intelligent optical networking era. This is also a major step forward for the “CTNET2025” network transformation strategy of China Telecom.

In addition, the investment in a ROADM network will improve the security of China Telecom’s optical transport network and its network intelligence, and intelligent operation capabilities. Better broadband user experience for Internet enterprises, e-commerce, and government/enterprise customers is the other benefit.

This project covers 21 ROADM sites in Hubei, Jiangxi, Anhui, Jiangsu, Zhejiang, and Shanghai along the middle and lower reaches of the Yangtze River.

The CD-ROADM technology of Huawei facilitates 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 dynamic recovery.

The project can address the low latency and high performance requirements for DC private lines and top financial customers. Besides, the current phase of the project can provide more than 300 100G electrical lines and 100 percent network recovery capability.

“When and only when 100 percent transport, switch, and access are realized in the optical domain, and ROADM and OXC are introduced to the switching layer can a network be called strictly all-optical,” said Wei Leping, director, Science & Technology Committee, China Telecom.
