SHENZHEN, China -- Huawei, a leading global information and communications technology (ICT) provider, today announced that it successfully launched the industry’s first Giga DSL (digital subscriber line) prototype. The Giga DSL system employs time division duplex (TDD) to achieve a total upstream and downstream rate of 1,000 Mb/s over a single twisted pair.

In order to address obstacles related to limited bandwidth of FTTB (Fiber to the Building)/FTTC (Fiber to the Curb) and difficulty in deploying FTTH (Fiber to the Home) drop cables – so that users can enjoy bandwidth-hungry services such as IPTV and HDTV – optical fiber access points need to be located closer to users. While, 100 Mbp/s-plus ultra-broadband access can be made available relatively quickly by utilizing legacy copper line resources, providing 1,000 Mbp/s bandwidth within 100 meters of twisted pairs using DSL technology is more complex.

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.
