By Telecom Lead Team: Huawei has won a bid to deploy the
100G WDM network for Project 211 (phase 3) of the China Education and Research
Network (CERNET).
Covering the entire country, the coherent WDM technology
based 100G network will be the world’s largest in terms of geographic coverage.
With Huawei’s coherent WDM technology and OTN equipment,
the 100G network will cover metropolitan areas, such as Beijing, Shenzhen,
Shanghai, and Chongqing.
The 100G network will have the capability to offer a
bandwidth of 8 Tbit/s over a single fiber, a transmission distance of 11,400 km
and 913km biggest single span without REG (Regenerator), and it will allow
co-transmission of 100G traffic with the existing 10G traffic.
Full compatibility with the legacy network ensures smooth
capacity expansion and protects CERNET’s investment in network infrastructure.
In addition, the 100G network meets the ultra-broadband challenges by offering
a transmission rate (per wavelength) 10 times faster than mainstream networks,
and it will provide a solid foundation for the rapid development of China’s
education network in the next decade.
“Huawei’s deployment of the ultra-long-haul network
for CERNET is a significant milestone in 100G’s commercialization,” said
Mr. Cai Changtian, president of Transport Network Product Line, Huawei.
Huawei has deployed over 40 trial and 15 commercial 100G
networks to date. Huawei provides first-class transport network products,
including WDM/OTN/ MS-OTN, MSTP/Hybrid MSTP, microwave products, and end-to-end
network solutions.
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.
