Alcatel-Lucent trials VDSL2 vectoring with China Telecom, Tunisie Telecom

Alcatel-Lucent (Euronext and NYSE: ALU) has announced a pair of field trials for its VDSL2 vectoring technology (see “Alcatel-Lucent announces Zero Touch Vectoring for VDSL2 broadband”). One, with China Telecom, is touted as the first such trial in China. The other was with Tunisie Telecom.

Vectoring is a noise cancellation technology which, when paired with channel bonding, can enable VDSL2 networks to support download speeds of up to 100 Mbps. Alcatel-Lucent and others have asserted the technology provides carriers with a large copper-based footprint a means of increasing broadband access data rates without switching to fiber to the home (FTTH).

The trial with China Telecom took place in Foshan, a city in Guangdong province of southern China. The field test used Alcatel-Lucent’s end-to-end System Level Vectoring technology implemented within the 7302 Intelligent Services Access Manager (ISAM) and G.vector customer premises equipment. China Telecom is evaluating the technology as a tool to achieve the goals of the country’s “China Broadband” program, which include supplying high-speed broadband connections to more than 250 million urban and rural homes by 2015.

In Tunisia, the field test with Tunisie Telecom saw the transmission of 100-Mbps signals downstream over a distance of 600 m, with upstream rates of 40 Mbps. The trial, which took place this past December, also used the ISAM 7302 platform.

"VDSL2 vectoring technology will allow us to quickly deliver advanced broadband services to meet our customers’ growing demands for more innovative, better quality and more value added services,” Nizar Bouguila, CTO of Tunisie Telecom, said. “We are very pleased with the test results, which were achieved thanks to Alcatel-Lucent's great support.”
