Australia's NBN to deploy G.fast in 2018

Australia’s broadband network, NBN, confirmed plans to deploy G.fast beginning next year.

G.fast becomes another access technology in NBN's "multi-Technology toolkit." G.fast technology will be supplied by the company's three existing fixed-broadband suppliers Nokia, ADTRAN and Netcomm Wireless.

G.fast can take broadband speeds past the current 100Mbps levels delivered by VDSL technology to deliver speeds of up to 1Gbps over copper lines by using higher frequencies of either 106MHz or 212MHz – compared to just 17MHz on VDSL.

JB Rousselot, Chief Strategy Officer, nbn said "adding G.fast to the toolkit for the FTTC and FTTB networks will allow us to deliver ultra-fast services faster and more cost effectively than if we had to deliver them on a full Fibre-to-the-Premises connection."

AT&T Rolls G.fast to MDUs in 22 Metros

AT&T is now rolling out G.fast Internet service for apartment and condominiums (MDUs) in 22 major metro areas across the United States. G.fast can be deployed immediately in MDUs in parts of the following metros:

Boston
Denver
Minneapolis
New York City
Philadelphia
Phoenix
Seattle
Tampa

Additionally, AT&T is offering G.fast to MDUs in parts of 14 other metros, including:

Albany, N.Y.; Baltimore; Buffalo, N.Y.; Cincinnati; Colorado Springs, Colo.; Hartford, Conn.; Omaha, Neb.; Pittsburgh; Portland, Ore.; Providence, R.I.; Richmond, Va.; Rochester, N.Y.; Washington, D.C.; Salt Lake City

Each of these metros is located outside of AT&T's traditional 21-state home Internet service-area.

"We're tapping into the existing internet infrastructure in some multifamily properties to bring ultra-fast internet in less time and with less disruption than replacing the network with fiber," said Ed Balcerzak, senior vice president, AT&T Connected Communities. "While fiber to the unit remains the best broadband solution for most properties where possible, G.fast and fixed millimeter-wave provide connectivity to properties that aren't able to support fiber. AT&T is committed to providing apartments and condos with connectivity across the nation, and innovations such as G.fast are helping us to do that."

ADTRAN's new G.fast extends gigabit services 650m beyond fiber endpoint

ADTRAN introduced a new Gfast deployment model to enable network operators to deliver gigabit speeds as widely as possible throughout their networks.

This is accomplished by combining ADTRAN’s 2nd generation SDX 2200 series of 212MHz, reverse powered Gfast DPUs with the ADTRAN bonded Super-Vectoring (VDSL2 35b) technology, providing gigabit rates from existing cabinet infrastructure and thus extending gigabit services significantly.

ADTRAN said that while Fiber to the Distribution Point (FTTdp) or Building (FTTB) solutions extend fiber services by 50 -100m, its new Gigabit-to-the-Basement (GTTB) solution enables gigabit services to be extended out to 650m from where the fiber ends. This added distance eliminates construction requirements that can often delay service roll outs, enabling service providers to offer gigabit services in just days or weeks versus months or years.

“This innovative solution combines two next-generation ultra-broadband technologies, and allows service providers to use either fiber or bonded vectored VDSL2 to backhaul Gfast services,” said Werner Heinrich, Director, Portfolio Management, Broadband Solutions, ADTRAN. “This announcement showcases ADTRAN’s ability to deliver disruptive solutions to the market, utilizing our deep domain experience in sealed outside plant, reverse power and market leading ultra-broadband technologies like Gfast and Super-Vectoring to enable our customers to meet market demand and exceed their customers’ expectations.”

Dell'Oro forecasts G.fast revenue growth of 600% in '19

According to its latest Broadband Access 5-year Forecast Report from Dell’Oro Group, G.fast revenue growth is set to increase by almost 600% in 2019 as operators complete testing and trials of G.fast amendment 3 chipsets and systems.

While the market for G.fast has been slow to develop initially, Dell'Oro predicts that 2019 will be the year when G.fast sees significant adoption, which will then have a knock-on effect on the future development of broadband access markets worldwide, including based on PON, DSL and cable/coax technology.

Dell'oro expects that momentum in the G.fast market will continue through the 5-year forecast period, and anticipates that G.fast revenue will account for more than a third of the overall DSL market by 2021.


Commenting on the report, Alam Tamboli, senior analyst at Dell’Oro, said, "Operators are holding off on massive deployments throughout their networks until they have more hands-on time with amendment 3 chipsets and systems, which will be available in early 2018… furthermore, many operators that wish to deploy G.fast into larger buildings via FTTB architectures are waiting for 32 or higher port-count units to be tested more thoroughly".

Nokia and Openserve Test G.fastt in South Africa

Nokia and Telkom South Africa wholesale division Openserve announced they have conducted a trial of G.fast technology in an office complex in Pinelands, South Africa, during which they achieved fibre-like access speeds over existing copper infrastructure deployed into buildings.

Nokia noted that the trial was carried out in preparation for Openserve's commercial deployment of G.fast planned for later in 2017.as part of the company's program to quickly expand its network footprint across South Africa.

The G.fast trial with Openserve demonstrated an aggregate, upstream and downstream, bandwidth of 900 Mbit/s over short copper loops, and speeds of up to 500 Mbit/s downstream and 250 Mbit/s upstream on an existing copper line over a distance of 150 metres.

Nokia's G.fast technology uses the final few hundred meters of copper within a building to deliver ultra-broadband access to end users. The solution is designed to allow Openserve to meet growing demand for fibre-like broadband speeds without significantly increasing its operational cost. The Nokia solution incorporates vectoring technology to reduce cross-talk interference between copper lines and help to increase data speeds.

Nokia noted that G.fast technology is increasingly being used in locations that are difficult or costly to reach with fibre as it allows operators to deploy fibre to the building and avoid the need to install it all the way to each individual unit. G.fast uses existing copper lines in a building, thereby also helping to reduce disruption.

Nokia claims to be the leading vendor for G.fast technology, with more than 40 customer trials completed and 10 customers commercially deploying the technology worldwide, including BT Openreach in the UK, Chunghwa Telecom in Taiwan, A1 Telekom Austria, Energia Communications in Japan and Frontier in the U.S.



  • Nokia recently announced that Frontier Communications had selected its G.fast technology to increase in-building broadband speeds for residents of apartment and multi-dwelling units (MDU) across Connecticut.

Germany's NetCologne and ZTE demo G.fast@212 MHz

ZTE and NetCologne, a regional network operator in the great Cologne-Bonn area of Germany and a subsidiary of utility company GEW Köln, which in March announced with ZTE the launch of the pilot phase of a G.fast roll-out, have jointly announced the G.fast@212 MHz profile ultra-broadband solution at the ANGACOM broadband exhibition in Cologne.

In what the companies claim is the first demonstration of G.fast@212 MHz, the technology is being tested over a live network. As part of the demonstration ZTE and NetCologne showcased the access rate profile of G.fast@212 MHz reaching more than 1.8 Gbit/s, with a download rate 1.6 Gbit/s and upload rate of around 200 Mbit/s. ZTE's G.fast solution is designed to enable NetCologne's fibre-to-the-building (FttB) access network to support gigabit bandwidth.
NetCologne stated that it is committed to providing the city of Cologne and surrounding regions with reliable, advanced telecom services, and has cited a target of reaching 260,000 homes. The company operates four data centres and offers a service portfolio that includes voice and data services and distribution of TV services for both residential and business users, as well as business ICT solutions.



  • NetCologne and ZTE signed the agreement defining their strategic partnership in February of this year. Under the terms of the agreement, ZTE will provide NetCologne with advanced network equipment including G.fast distribution point units (DPUs) and terminals.
  • ZTE's multi-port G.fast DPU supports G.fast@212 MHz and flexible uplink selection among PON/point-to-point/DSL (PON/P2P/DSL) technologies. The solution also features multiple power supply options, allowing it to self-adapt for a range of deployment scenarios.
  • Through the agreement, ZTE will help NetCologne to upgrade its existing VDSL network to a G.fast network. This solution will enable NetCologne to cost-effectively provide access at rates approaching 2 Gbit/s while utilising the existing copper infrastructure, without the need for fibre reconstruction in the residential network.

Frontier to deploy Nokia's G.fast in Conn.

Frontier Communications will deploy Nokia's G.fast technology to increase in-building broadband speeds for customers living in apartment and multi-dwelling units (MDU) across Connecticut. The project is described as a state-wide network expansion initiative. Financial terms were not disclosed.

Nokia said its G.fast solution will allow Frontier to use the last few hundred meters of existing copper located in buildings to deliver ultra-broadband access to customers. The solution leverages SDN and is compliant with NetConf and Yang models.

Steve Gable, Frontier EVP and Chief Technology Officer said: "Nokia's field-proven G.fast solution will help Frontier quickly bring ultra-broadband access to customers by using the existing copper twisted pair wiring that is often found in apartment buildings. Without it, we'd have to drill holes and pull fiber into each apartment unit we serve, a time consuming and challenging process that can be frustrating for customers. Nokia's solution allows us to deliver new enhanced services without ever having to enter the place of residence."

ADTRAN demos ITU G.fast 212 MHz and coordinated DTA

ADTRAN has announced that it is conducting what is believed to be the first public demonstration of the ITU-T's two most recent G.fast advances, specifically 212 MHz and coordinated dynamic time allocation (cDTA), at the G.fast Summit 2017 in Paris.

ADTRAN noted that the latest G.fast advances are intended to enable the delivery of symmetric gigabit services over a single copper pair, mitigating the need to bond multiple pairs of copper wire and allowing service providers to extend business-class gigabit services over the existing wiring.

At the G.fast Summit ADTRAN is demonstrating its new 212 MHz G.fast standard, which doubles the usable spectrum and enables the delivery of gigabit rates over a single copper pair and offering an alternative to the use of fibre. ADTRAN has also extended its reverse power feature set to the new solution, simplifying sourcing of local power.

Together, the new capabilities are claimed to enable service providers to accelerate gigabit and ultra-fast broadband service deployments by an estimated 12 to 18 months and reduce costs by up to one third per subscriber. The technology is also intended to offer a competitive alternative to DOCSIS 3.1.

ADTRAN noted that it first demonstrated DTA over coax technology at G.fast Summit 2016, with cDTA the second generation technology. The cDTA function can improve G.fast upstream performance by a factor of four- to five-fold by dynamically balancing upstream and downstream performance to match residential traffic patterns in real-time. Unlike DTA, cDTA extends the applications of the feature to existing phone wiring in residential and commercial premises.

Designed to form a key part of the ADTRAN MOSAIC Open Software Defined Access platform, operators adopting the new solutions can ensure that the G.fast access elements in their network are prepared for the transition to SDN in the future.

NetCologne Tests G.fast and GPON with ZTE

ZTE and German regional network operator NetCologne, which in mid-February formed a partnership for the roll-out of GPON and G.fast technology, have now announce the launch of the G.fast pilot phase.

Jointly developed by ZTE and NetCologne, the new G.fast technology that will be deployed is designed to support transmission speeds of up to 1 Gbit/s, with such speeds verified in the lab. The companies are currently implementing the first live connections in real-world conditions in the pilot phase of the project. NetCologne stated that G.fast technology will be made available on its network during 2017, with a target of serving around 260,000 households.

The deployment of G.fast technology is intended to enable NetCologne to cost-effectively connect buildings utilising the existing copper cabling infrastructure to its fibre network and deliver bandwidth of up to 1 Gbit/s to customers. ZTE noted that the project is specifically employing its combined GPON/G.fast offering, which includes its latest 2U-high DSLAM products and G.fast gateways.

NetCologne, a subsidiary of utility company GEW Köln, is a regional network operator in Germany serving the greater Cologne-Bonn area. Under the agreement with ZTE announced in February, the companies stated they would jointly develop projects involving GPON and G.fast technology. Specifically, ZTE was to support NetCologne as it expanded and enhanced its service offering, initially via transitioning the existing VDSL-FTTB network toward GPON using G.fast technology.

ZTE noted at that time that GPON would serve as an uplink technology, with G.fast used to expand the existing FTTB infrastructure and integrate into NetCologne's network infrastructure that includes around 23,500 km of fibre.

NetCologne stated that in June 2016 it selected ARRIS International's Touchstone TG2492 gateway to enable gigabit broadband and enhance wireless broadband coverage for its subscribers in the Cologne area. Following development work it has developed a new type of DSLAM designed to meet the requirements of G.fast that will be installed as an interconnection point in building basements.

NetCologne noted that as the new DSLAM utilises a larger frequency spectrum than the existing FTTB DSLAMs, it enables the transfer rate to be increased in the future, by the current 100 Mbit/s to up to 1 Gbit/s.

During the ongoing pilot phase with ZTE, speeds of up to 1 Gbit/s will be tested over connections with different customer terminals. It was noted that the frequency spectrum from 2.2 MHz up is currently used for data transmission, leaving out the ADSL transmission range, while testing with the first ZTE G.fast chip generation currently utilises the frequency band up to 106 MHz. Using the new chip generation that is in development, the frequency spectrum can be doubled and increased to 212 MHz.

ITU Bumps G.fast to 2Gbps, Adds Support for Coax

The ITU-T Study Group 15 has doubled the G.fast standard to support top down link speeds of 2 Gbps.

The first ITU standard harnesses up to 106MHZ of spectrum frequency to deliver top speeds of 1Gbps on copper lines of less than 50 meters. The updated standard will allow 212MHz to be used.  The amendment also enables G.fast to be used over coaxial copper cables.

The amendment also specifies a mechanism for dynamic time assessment, functionality that enables upstream or downstream transmission to exploit G.fast’s full aggregate net data rate. This functionality will improve users’ broadband experience by increasing upload or download speeds in line with the demands of the applications in use.

In addition, the new ITU-T G.7701 “Common Control Aspects” describes commonalities in SDN and ASON network management-control, covering common SDN and ASON control approaches as they relate to transport resources and their representation, control components, control communications, and naming and addressing.

Australia's nbn Hits 8 Gbps in Testing Nokia's XG-FAST

In lab testing, Australia's nbn recorded throughput speeds of 8 Gbps using Nokia's XG-FAST solution. Specifically, the XG-FAST trial conducted in nbn's North Sydney-based lab facilities generated peak aggregate data throughput speeds of more than 8 Gbps over a 30-meter twisted-pair copper cable typically deployed in field. A 5Gbps peak aggregate speed was achieved over 70 meters of twisted-pair copper cable.

XG-FAST is a Nokia Bell Labs-developed extension of Nokia's commercially available G.fast.  Nokia said the technology can deliver fiber-like speeds of more than 10 Gbps over short distances using existing copper infrastructure.

Dennis Steiger, CTO at nbn said: "Although XG-FAST is still in its very early stages of development, the lab trials we have conducted demonstrate the huge potential that the technology offers. XG-FAST gives us the ability to deliver multi-gigabit speeds over copper lines - virtually on a par with what is currently available on Fiber-to-the-Premises - but at a lower cost and time to deploy. We are really thrilled to be the third operator in the global market to run lab trials of XG-FAST, following in the footsteps of BT last year and Deutsche Telekom in February. This shows that nbn is committed to delivering Australians the best possible broadband experience on the nbn(TM) network."

Deutsche Telekom Tests XG-FAST over Copper with Nokia

Deutsche Telekom hit throughput speed of more than 10 Gbps in a trial or Nokia's XG-FAST technology that was conducted at Deutsche Telekom's cable laboratory in Darmstadt, Germany. The trial used two bonded pairs of Category 6 cable at 50 meters in length. Similar tests using standard drop cable illustrated the feasibility of XG-FAST for fiber-to-the-front door applications, achieving aggregate rates that exceed 8Gbps over 50m.  All trials were performed using prototype equipment from Bell Labs under laboratory conditions.

XG-FAST is a Bell Labs-developed extension of Nokia's commercially available G.fast technology. The lab trial was conducted end of 2015 by Nokia's subsidiary Alcatel-Lucent.

Deutsche Telekom's network - which uses VDSL2 Vectoring as well as fiber-to-the-home (FTTH) technology - currently offers customers access speeds of up to 100 Mbps.

Nokia said  XG-FAST is in the early stages of lab testing, but has exceeded expectations in trials with several customers so far.

XG-FAST is also capable of delivering 1Gbps symmetrical services at distances of 70m enabling operators to deliver fiber-like speeds inside buildings using existing telephone lines, eliminating the need to install new cabling. This allows for faster installation times and less hassle for the end-user.

CenturyLink Rolls with G.fast

CenturyLink claims the largest G.fast deployment in the United States: Platteville, Wisconsin, where the carrier has installed G.fast technology in 44 multi-dwelling units (MDUs) to provide internet speeds of up to 500 Mbps and higher to nearly 800 apartments.

CenturyLink said it is evaluating other locations, beyond MDUs, where G.fast technology can be used to give customers access to faster speeds, such as fiber-fed multi-tenant units (MTUs) and neighborhoods where fiber-to-the-curb (FTTC) allows for G.fast to push higher speeds over the short amount of copper into the home.

The rollout uses the Calix AXOS G.fast solution, with all systems and services managed via the cloud through Calix's Compass Consumer Connect Plus software.

In 2015, CenturyLink deployed fiber-to-the-premises technology to the majority of residential and business customers in Platteville to upgrade the CenturyLink Televideo TV service to CenturyLink Prism TV service and to offer broadband speeds up to 1 Gbps.

"We saw a great opportunity to use existing copper assets in our Platteville network to bring ultra-fast internet speeds to customers who live in areas that typically don't have access to these new broadband technologies delivering higher speeds," said Aamir Hussain, CenturyLink executive vice president and chief technology officer. "We take a fiber-first approach when deploying faster broadband speeds but enabling G.fast over copper infrastructure helps us reduce costs, speed time to market and effectively connect our customers to the power of the digital world in areas where fiber deployment is less feasible."

BT Trials Cloud RAN Fronthaul over G.fast

BT is testing G.fast technology to deliver a ‘Cloud Radio Access Network’ (C-RAN) cellular network service over copper, in an experiment believed to be a world first.

Researchers at BT’s Adastral Park Labs, in collaboration with Cavium, have demonstrated that they can use G.fast technology to deliver cellular data over copper lines at speeds of 150 – 200Mbps.

BT said the conventional view has been that fiber would be required in C-RAN architecture for connecting cellular base stations to a central facility in the core network. This approach uses G.fast over copper for the fronthaul connection.

Dr Tim Whitley, MD for Research & Innovation at BT said: “Using G.fast to deliver a cellular network is an exciting breakthrough for C-RAN and yet another world first for our team of researchers at Adastral Park.

“These technologies will play a key role in 4G networks and will be fundamental to 5G architectures. The trials are another step towards a fixed and mobile network which will support customers’ increasing demands for data.”

“We are very excited to collaborate with BT, using Cavium OCTEON Fusion-M basestation and ThunderX server processor technology to validate this new class of Radio Access application with G.fast technology.” said Raj Singh, General Manager of Cavium’s Wireless Broadband Group.

As well as exploring the role that G.fast may play in helping operators to roll out their 4G/5G networks, Openreach, BT’s local access network division, is also trialling G.fast as an access technology in Huntingdon and Gosforth, alongside a further BT technical trial in Swansea. G.fast is significant because by building on current Fibre-to-the-Cabinet (FTTC) technology, it allows Openreach to bring ultrafast speeds to a wide footprint far more rapidly and without the expense and disruption of running fibre directly into a home or business.

Broadband Forum Completes FTTdp Work

The Broadband Forum completed work on the management of Fiber to the Distribution Point (FTTdp), which aids in the management of fiber-fed nodes in the periphery of the access network.

At the Broadband Forum’s quarterly meeting in Mexico, it was agreed that the FTTdp YANG management model was ready for release exclusively to members for testing in network equipment. This is the Forum’s first software project written in the YANG modelling language.

“This is great news for our members whether they be service providers, vendors or test houses,” said Broadband Forum CEO Robin Mersh. “By adopting YANG modelling we are in the process of moving the management of FTTdp from the drawing board into the network, helping to drive open interoperability between different devices. This means service providers can offer competitive ultrafast services such as G.fast.”

Regarding G.fast, the Forum approved the University of New Hampshire Interoperability Labs (UNH-IOL) as a test facility for the latest G.fast plug-fest – paving the way to the industry’s first certifications.

“The success of the Forum in accelerating broadband innovation would not be possible if it weren’t for the expertise and energy of its members,” said Kevin Foster, Chairman of the Broadband Forum. “When the Broadband Forum started there were less than a million broadband connections and now there are more than 750 million. This is an extraordinary achievement and one that would not be possible without the hard work and commitment of our members, like Les, on our various projects.”
