Huawei tests Gigabit DSL

Chinese equipment vendor Huawei has shown it can achieve DSL Gigabit speeds over short distances, the company said on Wednesday. The new technology uses time division duplexing to achieve a total upstream and downstream rate of a gigabit over a single twisted pair.

By using low-power spectral density in-signal transmission, Huawei's Giga DSL prototype reduces radiation interference and power consumption, and provides a total upstream and downstream rate of one Gb/s within 100 meters, and 500 Mb/s-plus within 200 meters — making it a cost-effective option for telecom operators building ultra-broadband access networks.

Huawei also recently announced the successful development of the world's first node level vectoring (NLV) prototype. Huawei's vectoring product provides 100 Mbps access over a single twisted pair in FTTC/FTTB, and has been tested and commercially trialed with many leading telecom operators. This, along with the company’s latest prototype, Giga DSL, signifies that DSL technology still has great potential to meet the requirements of broadband users for ultra-high-speed access in the future.
