CERNET partners with Huawei to deploy world's largest 100G network

Huawei Technologies Co Ltd. says it has won a bid to deploy the 100-Gbps WDM network for Project 211 (phase 3) of the China Education and Research Network (CERNET). Covering the entire country, the coherent WDM-based 100G network will be the world's largest in terms of geographic coverage, the company claims.

Huawei Technologies Co. Ltd. says it has won a bid to deploy the 100-Gbps WDM network for Project 211 (phase 3) of the China Education and Research Network (CERNET). Covering the entire country, the coherent WDM-based 100G network will be the world's largest in terms of geographic coverage, the company claims.

Using Huawei’s coherent WDM technology and Optical Transport Network (OTN) equipment, the 100G fiber-optic network will offer a bandwidth of 8 Tbps over a single fiber, a total transmission distance of 11,400 km, and a biggest single span of 913 km without regeneration.

The network will allow co-transmission of 100G traffic with the existing 10G traffic, ensuring smooth network upgrades. Full compatibility with the legacy network protects CERNET's investment in network infrastructure, Huawei says.

"Huawei's deployment of the ultra-long-haul network for CERNET is a significant milestone in 100G’s commercialization," said Cai Changtian, president of transport network product line, Huawei.

Huawei says it has deployed over 40 trial and 15 commercial 100G networks to date. According to consulting firm Ovum, Huawei ranked No. 1 in the global optical network market, WDM/OTN market, and 40G network market, as of Q3 2011.
