Huawei has showcased a 700 Mb/s DSL (Digital Subscriber Line) prototype in Hong Kong – the first of its kind in the world – that enables operators worldwide to build high-bandwidth, cost-effective, and future-proof broadband access networks with SuperMIMO (multiple-input multiple-output) technology.

The company said this prototype far exceeds the industry’s current DSL broadband wireline communications technology, which reaches a data rate of 100 Mb/s, and is better, suited to meet the needs of operators supporting ultra broadband services.

You Yiyong, president of Huawei's Access Network Product Line, said, "DSL technologies for broadband access are showing great market potential. As a leader in the development of DSL technologies, our newest DSL prototype demonstrates our commitment to providing customer-centric and groundbreaking solutions and services for operators to enhance their competitiveness and profitability.”

SuperMIMO technology uses four twisted pairs to achieve a downstream rate of 700 Mb/s at a distance of 400 meters. This technology methodically addresses crosstalk among multiple twisted pairs and increases DSL bandwidth by 75 percent, from an average of 100 Mb/s per twisted pair to approximately 175 Mb/s.

Leveraging SuperMIMO, Huawei’s 700 Mb/s DSL prototype accommodates high-speed FTTB/FTTC access and bandwidth-hungry private line applications, such as base station access.
