NBN Co deploys DOCSIS 3.1, restarts stalled HFC rollout

NBN Co says it has started deploying DOCSIS 3.1 technology into its HFC pay-TV network, the rollout of which has been stalled for months because of problems with the existing networks.

NBN Co says DOCSIS 3.1 will double the downstream capacity on the HFC network, and it plans to have around three million premises receiving the NBN on HFC by 2020. It says users already on HFC will see an immediate benefit, because their on-premises equipment is already able to support DOCSIS 3.1

DOCSIS 3.1 can support higher speeds than the current technology, but NBN Co says the most important feature is that it will enable its rollout to be accelerated.

Before launching DOCSIS 3.1, the only way NBN Co could increase capacity on the HFC network was by installing new optical nodes to reduce the number of premises served by the existing optical nodes on the network.

NBN Co started reselling HFC services in June after a six-month hiatus. It expects to release around 100,000 homes and businesses on the HFC network to retailers every month through to April next year. – Stuart Corner
