Nokia Bell Labs achieves 10Gbps symmetrical over HFC

18 May 2016

Nokia Bell Labs announced it has achieved the first 10Gbps symmetrical data speeds over traditional hybrid fiber coaxial cable.

Using a prototype technology developed at Bell Labs called XG-CABLE, the test used point-to-point cable topologies to deliver 10Gbps symmetrical data speeds over coaxial cable using 1.2GHz of spectrum.

Nokia said the technology is capable of being easily integrated into CableLabs' new Full Duplex DOCSIS 3.1 concept, potentially allowing operators to more effectively provide ultra-broadband speeds to premises where it is not physically or economically viable to use fiber for the last mile.

The 10Gbps symmetrical speeds were achieved using a point-to-point 100m coaxial drop cable. The trial also achieved 7.5Gbps symmetrical data speeds using a network design based on fiber-to-the-last-amplifier, also known as a point-to-multipoint coax drop.

Nokia Bell Labs' echo canceling technologies were used for the design of the cable.

“The proof of concept demonstrates that providing 10Gbps symmetrical services over HFC networks is a real possibility for operators,” Nokia president of fixed networks Federico Guillén said.

“It is an important achievement that will define the future capabilities and ultra-broadband services cable providers are able to deliver.”
