Huawei Technologies Co Ltd. (\"Huawei\"), a leader in providing next generation telecommunications network solutions for operators around the world, has announced that it has been selected by China Telecom to build China\'s first 40G WDM (Wavelength Division Multiplexing) transmission network between Shanghai and Wuxi.

Under the terms of the contract, Huawei will provide China Telecom with an ultra-high-capacity 80 wavelengths x 40G transmission solution 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 launched the world’s advanced 40G solution, which has since been deployed in Europe, North America, and Asia Pacific. Huawei\'s 40G transmission solution provides the most comprehensive coding technologies in the industry, delivering the most cost-effective solutions across different application scenarios. 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. 40G transmission solutions also adopt Huawei’s 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 3.84T which is the largest in the industry.

\"It is an honor to work with China Telecom in building China\'s first 40G WDM transmission network,\" said 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.\"

Huawei\'s 40G transmission solution has been widely recognized in the industry winning an InfoVision Award from the International Engineering Consortium (IEC) in 2008. Huawei has also deployed the industry\'s longest 40G commercial trunk with no electric regeneration and has announced the successful development of a 100G WDM prototype.
