Australia’s National Broadband Network (NBN) association has reliable that it will muster DOCSIS 3.1 network stop inclination (NTDs) opposite a hybrid fibre-coaxial (HFC) network by Mar subsequent year to concede for gigabit speeds.
According to a new shred on NBN’s Integrated Product Roadmap [PDF], a HFC DOCSIS 3.0 NTD swap-out will take place between Oct 23, 2017, and Mar 30, 2018.
DOCSIS 3.1 will be switched on thereafter, with NBN final month observant a “potential blurb launch” during 2018.
NBN in Jun announced attaining gigabit speeds during a lab hearing of DOCSIS 3.1 over a HFC network, forward of serve lab tests in Aug and margin trials in December, while CEO Bill Morrow told Senate Estimates in May that NBN is now deploying DOCSIS 3.1-capable modems for a HFC network.
NBN’s initial DOCSIS — Data Over Cable Service Interface Specification — 3.1 trial, conducted in Melbourne, saw download speeds of 1Gbps and upload speeds of 100Mbps.
Fibre to a premises (FttP) is now a usually NBN record means to offer 1Gbps speeds until DOCSIS 3.1 is switched on for HFC customers, after being behind from launching in a second half of 2017.
ZDNet understands that NBN is also vocalization with vendors to control a hearing of Full Duplex DOCSIS able of 10Gbps exquisite speeds once standards are finalised, after formerly hailing Full Duplex DOCSIS — that record partner Nokia used to achieve 10Gbps exquisite speeds during a hearing opposite HFC networks — after CableLabs denounced it in Feb final year.
In comparison to frequency-division duplex (FDD) and time-division duplex (TDD), Full Duplex DOCSIS sees both downstream and upstream trade share a same spectrum. Symmetrical multi-gigabit broadband services are done probable by DOCSIS 3.1 record when total with Full Duplex DOCSIS.
According to NBN’s latest corporate plan, only 2.5 million to 3.2 million premises, or 21 to 27 percent of a population, will be lonesome by HFC — down from a 34 percent listed underneath a aged plan.
Subsequent to edition this number, however, NBN moved around 400,000 premises in a HFC footprint over to new fibre-to-the-distribution-point (FttDP) network record due to carrying to replace a Optus HFC footprint with a FttDP network. A leaked NBN breeze in Nov 2015 suggested that Optus’ HFC network was “not entirely fit for purpose”.
