Comcast, Australian NBN to Deploy DOCSIS 3.1 in 2016, 2017
It isn’t clear precisely when, and in what quantities, the DOCSIS 3.1 standard will be commercially deployed, but Australia and the United States likely will be early to do so.
Comcast has said it will deploy DOCSIS 3.1, designed to support 10 Gbps in the downlink, early in 2016.
NBN Co in Australia has said it will introduce “Data Over Cable Service Interface Specification 3.1 (DOCSIS)” by about 2017.
DOCSIS 3.1 supports download speeds of up to 10Gbps and up to 1Gbps upstream.
More than three million homes and businesses in Brisbane, Melbourne, Perth, Adelaide, Sydney and the Gold Coast are earmarked to receive the National Broadband Network over the Hybrid Fibre Coaxial (HFC) network that presumably will be engineered to support DOCSIS 3.1, even if DOCSIS 3.0 initially is used by many consumers.
The issue is largely dictated by marketplace realities. Not many consumers will happily pay hundreds of dollars to buy a multi-gigabit service, when lower-cost megabit services that work well can be purchased.
