“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 patented SuperDRZ technologies supports ultra long-haul transmission of up to 1,500 kilometers without the need for regeneration, which reduces investment costs. 40G transmission solution also adopts 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.
