BT tests G.Fast with Huawei

BT tests G.Fast with Huawei
Huawei announced a technical field trial with BT of its G.Fast technology to boost the speed of copper lines to levels similar to fibre. Huawei said the technology has the possibility to support Gigabit speeds without causing the major upgrade disruption associated with fibre-to-the-premises technology. 

The G.Fast trial is located close to the BT Adastral Park R&D centre in Ipswich and includes multi-port G.Fast equipment installed in underground distribution points. G.Fast uses time division duplex (TDD) technology and supports up to 1 Gbps bandwidth access per twisted pair within a distance of 100 metres, a tenfold speed increase compared with VDSL2 access. Vectoring technology is used to reduce cross talk on the copper pairs. 

The G.Fast technology can work at distances of up to 250 metres, and Huawei said most typical drop cables in the UK are considerably shorter. The ITU is expected to release a draft of the G.Fast standard, to which Huawei has contributed, by the end of 2013.

BT using Huawei equipment for G.fast trial

Huawei announced that it supplied G.fast equipment to BT for the UK's recently announced first large-scale customer trial of the technology in Huntingdon. The manufacturer provided a headend optical line terminal, G.fast terminal, network management system and remote power solution. In October 2013, Huawei collaborated with BT to launch the world's first G.fast pre-standard field trial.

BT Openreach picks Swansea as third city for G.Fast trials

BT Openreach announced at a UK Network Operators Forum (UKNOF) meeting this week that it plans to run a G.Fast trial in a third city, Swansea, reports Think Broadband. The company had previously announced that it would hold trials of the technology offering 330 Mbps downstream and 30-50 Mbps upstream in Gosforth and Huntingdon. The trials stating this summer will pass around 4,000 homes with two service options, G.Fast and a new faster fibre on demand product offering 500 Mbps to 1 Gbps.

BT to start two G.fast city pilots this summer

BT plans to test G.fast in two pilot locations in summer 2015 and hopes the technology will allow it to deliver up to 500 Mbps speeds to most of the UK by 2025, CEO Gavin Patterson announced. Connecting Cambridgeshire superfast broadband programme welcomed the announcement that one of the pilots will be in Huntington. The other will be in the Gosforth area of Newcastle. Around 4,000 homes and businesses will be able to take part at both locations. If the new technology proves successful, deployment will sta

ITU gives final approval for G.fast standard

ITU members have achieved final approval of G.fast, the new broadband standard designed to deliver access speeds of up to 1Gbps over existing phone lines. The standard answers to service providers' need for a complement to fibre to the home (FTTH) technologies in scenarios where G.fast proves the more cost-efficient strategy. The Broadband Forum will run its first plugfest for January 2015 to ensure compliance with the G.fast standard and certify chipsets and equipment.

Huawei unveils first SuperVector technology prototype

Huawei has introduced a new technology prototype, dubbed SuperVector, which it claims substantially boosts copper access speed when compared to VDSL2 vectoring. In lab tests conducted with European operators, Huawei said the SuperVector prototype achieved 400 Mbps over 300 meters copper, which is three times the speed of VDSL2 vectoring, and 100 Mbps over 800 meters copper, which is suitable for 4KTV services. Huawei explained that SuperVector technology works by extending the frequency band from 17 MHZ to

BT achieves 786 Mbps downstream in G.fast trial

BT has completed a trial of Fibre To The Disribution Point (FTTdp) G.fast technology at its Adastral Park R&D centre in Ipswich which achieved 786 Mbps downstream and 231 Mbps upstream over a 19 meter length of copper. On a longer line of 66 meters, speeds reached 696 Mps downstream and 200 Mbps upstream. BT's local access network business Openreach, currently passes over 20 million UK premises with a mix of Fibre to the premises and Fibre to the cabinet technology. With FTTdp, the fibre is closer to the pr

BT Openreach starts new VDSL vectoring trial

The second phase of BT Openreach's VDSL vectoring (ITU-T G.993.5) trial has started and will run for at least three months. The vectoring technology can help boost speeds on BT's FTTC network by reducing crosstalk on broadband lines. The first trial, which began last September 2013 and continued for several months, proved to be broadly successful by enabling many more customers to achieve the top speed of 80Mbps, reports ISPreview.co.uk. The second phase will focus on the same three street cabinets in Barne

Broadband Industry is working full speed on G.Fast

G.Fast will be the next evolution for broadband over copper networks. Over a short loop, typically 100 meters, broadband speeds of over 1 Gbps are possible. The ITU has approved the G.Fast standards on 04 April, with finalization expected in December. The network industry has some comprehensive testing ahead, explains Robin Mersh, CEO of standards group Broadband Forum. He sees no reason for network operators not to deploy G.Fast. Equipment could be commercially available in early 2015.

ITU confirms G.fast standards

The International Telecommunications Union (ITU) has confirmed the final G.fast standards. ITU-T 9700 and ITU-T 9701 received preliminary approval in December 2013 and the definitions were confirmed on 04 April. G.Fast is the latest evolution of DSL, and the technology is expected to be ready for commercial deployment in 2016 at the earliest. G.Fast uses TDD (Time Division Duplex) technology across a much wider frequency range than ADSL or VDSL, namely up to 106 MHz or 2012 MHz. Over short distances, up to

Huawei unveils G.fast prototype with speeds at 1Gbps

Huawei has conducted its G.fast over copper trial with a leading European telecom operator and unveiled a prototype capable of broadband speeds of 1 Gbps over coaxial cables. G.fast over Coax multi-user access technology is compatible with cable TV signals on existing coaxial networks, which serve as an access medium for home networks. By flexibly allocating unoccupied frequency bands (1 GHz maximally) for G.fast access, the technology provides a 1 Gbps downstream shared bandwidth to serve up to 32 users ov

G.fast passes ITU first stage approval

The ITU's Study Group 15 has given first stage approval to a new Gigabit broadband standard called G.fast, which delivers up to 1 Gbps fibre performance over existing copper cables at lower costs by using vectoring technology. G.fast is designed to deliver superfast broadband downloads up to a distance of 250 meters, thereby eliminating the expense of installing fibre between the distribution point and people's homes. The study group's decision covered the ITU-T G.9700 recommendation, which specifies method

Alcatel-Lucent, A1 reach 1 Gbps in G.fast trial

Alcatel-Lucent and Austrian operator A1 announced a trial of G.fast vectoring technology supporting over 1 Gbps on a copper network. The new transmission technology G.fast uses a wide frequency band to achieve very high speeds on copper lines over very short distances. G.fast is intended for typical applications of 500 Mbps at 100 meters or less. Considered a low-cost alternative to deploying fibre directly to the premises, G.fast also addresses the vectoring problem of crosstalk interference between lines,
