AUGUST 5, 2008 -- Huawei Technologies Co Ltd. (search for Huawei) has been selected by China Telecom to build China's first 40G WDM transmission network between Shanghai and Wuxi.
Per the contract, Huawei says it will provide China Telecom with an ultra-high-capacity 80 wavelengths x 40G transmission system capable of 10G/40G hybrid transmission to address China Telecom's ever-increasing Internet bandwidth requirements and to lay a foundation for providing high-bandwidth services.
Huawei's 40G transmission system provides what the company claims are the most comprehensive coding technologies in the industry, delivering the most cost-effective options across different application scenarios, say company representatives. Huawei's patented SuperDRZ technologies support ultra long-haul transmission of up to 1,500 kilometers without the need for regeneration, which reduces investment costs. Huawei says its 40G transmission also utilizes its unique C-band extension technology, which increases the fiber transmission bandwidth by an extra 20% and enables the DWDM system to boast a transmission capacity of 3.84 Tbits, the largest in the industry.
"It is an honor to work with China Telecom in building China's first 40G WDM transmission network," contends Christian Chua, president of Huawei's Transport Network Product Line. "The proliferation of Internet services has put an ever-increasing demand on bandwidth. To jointly promote the commercial application of 40G technologies, Huawei, a leader in 40G transmission networks, will continue to focus on operators' pressures and challenges."
