Huawei extends tech to allow 1Gbps from twisted pair to HFC

The company, banned from working on the NBN, believes it would be able to achieve speeds of 1Gbps between the node and the premises.

Huawei has extended the technology that it believes could help bring fibre from the node to the premises by creating a world-first prototype over coaxial cable.

The technology takes advantage of unused frequency bands in existing hybrid fibre-coaxial (HFC) cables, typically used for delivering cable TV services. Huawei dubs the technology, and it can enable one cable to serve up to 32 users concurrently. It is the first time the company has been able to do this over an HFC network, and it achieved speeds of 1 Gigbit per second (Gbps).

However, as early as 2011, Huawei has been able to achieve the same speeds over twisted pair copper. Trials have been conducted with a European telecommunications operator, similarly reaching the 1Gbps speeds.

A spokesperson for the company confirmed with ZDNet that its prototype now allows it to provide over copper and HFC, but is still considered to be in a pre-standardised form. To overcome this and allow for greater adoption of, Huawei is submitting much of its research to the ITU Telecommunication Standardization Sector standards body.

Despite the technology being able to solve what has been one of the most contentious issues around the rollout of the National Broadband Network — delivering fibre to the premises or the node — Huawei was banned from bidding on work on the network, under the belief that the company represents a threat to national security .

Huawei has already been cleared of accusations that it spied on the US government , and the communications giant has claimed that the US market is a commercial disappointment , turning its focus to Europe instead.

Prior to the Coalition winning to the election, it said it may reassess the ban if it came into power. Since winning the 2013 election, no assessment has been made.
