G.fast is a new copper broadband technology that enables throughput of better than 1 Gb/s over a single twisted pair. The technology is based on a signal modulation scheme very similar to the DMT modulation used in VDSL2, with one notable exception, G.fast transceivers utilize time-division duplexing instead of the frequency-division duplexing used in VDSL2.

G.fast also borrows many other advances from VDSL2, including seamless rate adaption (SRA), bit swapping, retransmission, dying gasp, and vectoring. In addition, G.fast includes...

The University of New Hampshire InterOperability Laboratory (UNH-IOL) will host a multi-vendor G.fast interoperability demonstration with six vendors during next week’s Broadband World Forum (BBWF) in London with an aim to accelerate network rollouts and service delivery.

Calix, Digital Lightwave, Huawei, Metanoia Communications, Technicolor and Telebyte are among the vendors taking part in the demonstration.

During the event, UNH-IOL’s demo will show cross-chipset interoperability among solutions from multiple demarcation point unit (DPU) and customer premises equipment (CPE) vendors,...

The new broadband technology being championed by BT is a cost-effective way of delivering fast internet speeds, an expert has said. Lincoln Lavoie said fibre broadband is a futureproof long-term solution but comes “at a huge cost”. He said G.fast, which uses a combination of fibre cables and existing copper wires, is a “great solution” that can make the most of the UK’s current infrastructure.

G.fast is currently being trialled by BT customers in Gosforth, Newcastle, and Huntingdon, Cambridgeshire,...

The University of New Hampshire InterOperability Laboratory (UNH-IOL) hosted a plugfest earlier this month for vendors to test their latest VDSL2 vectoring equipment and software. The series of VDSL2 Vectoring Plugfest, organized by the Broadband Forum, have enabled participants to develop interoperable and deployable solutions. Participants included ADTRAN, Alcatel-Lucent, AVM GmbH, Broadcom, Calix, Ikanos, Lantiq, and Triductor.

“The plugfest test events serve a critical role in the industry, helping our member companies develop interoperable and robust solutions,” said Robin...
