Cisco Delivers 1 Gbps over HFC with Wideband DOCSIS

Cisco Systems announced "Wideband Protocol for DOCSIS", a new technology able to deliver up to 1 Gbps broadband speeds over existing hybrid fiber coax (HFC) networks. The protocol augments HFC network bandwidth by adding one of more additional downstream to the standard broadband DOCSIS system. This new set of downstream channels is grouped into one larger channel, and is known as a Wideband channel. Cisco said its Wideband Protocol for DOCSIS is compatible with existing DOCSIS 1.x and 2.0 specifications.


Himawari Network, a Japanese cable operator is testing the technology to deliver advanced commercial services. The trial, being conducted at the Toyota Dream Home at Aichi prefecture in Japan, will showcase the ability to converge video, data traffic onto a single IP-based service. The Himawari Wideband trial is based on Cisco's uBR10012 Cable Modem Termination System (CMTS) platform. As part of the trial, Linksys will provide the Wideband cable modem which can receive and process data streams transmitted by the CMTS on multiple radio frequency channels.
