Nokia, Deutsche Telekom test 10-Gbps XG-FAST in lab

Nokia says that its new Alcatel-Lucent subsidiary completed a laboratory trial with Deutsche Telekom of the latter's XG-FAST technology. Derived from G.fast, the XG-FAST technology was shown to support aggregate (upstream and downstream combined) throughput rates of more than 10 Gbps (in fact, more than 11 Gbps) over two bonded pairs of Category 6 copper in the trial, which was conducted at the end of 2015.

The systems house said XG-FAST was able to support such high data rates over a distance of 50 m.

The lab work also showed XG-FAST was able to support an aggregate 8 Gbps over 50 m of standard drop cable.

The trial used prototype equipment. XG-FAST is "in the early stages of lab testing," according to Nokia. The company says the XG-FAST also can support symmetrical gigabit transmission at a distance of 70 m. This makes the technology a good candidate for delivering gigabit services to apartment dwellers and other subscribers in multi-dwelling or multi-tenant applications, the company believes.

"Working on this demonstration we can see the future possibilities of XG-FAST in maximizing existing assets," said Bruno Jacobfeuerborn, CTO of Deutsche Telekom. "This will provide another technology option which could enable us to offer high-speed connectivity to our customers quickly and cost-effectively, and at the same time, move our fiber infrastructure closer to our customers."
