MetanoiaInteroperability demonstrated at BBWF. Metanoia's press release features a quote from Swisscom, one of the first to deploy G.fast. Their chips are in an SFP container, ready to plug into routers designed for SFP upgrades. They developed in cooperation with Huawei. They also offer DPU chips. All the telcos are looking for a second source for G.fast, unwilling to be tied to a single chip vendor. With Ikanos gone, there's plenty of opportunity.

The company is not well-known in the west. They have a substantial investment in R&D and a patent portfolio. They haven't released much information that isn't in the press release, below. I've sent a note and hope to learn more.

G.fast IOP, a first in a Carrier Network environment; Swisscom makes it a reality that meets their network requirements

Press release [Tuesday 18 October 2016]

Broadband World Forum 2016 - Metanoia Communications (Metanoia), a leading developer of very high speed xDSL PHY chipsets for the wireline broadband market, announces today that they have achieved interoperability (IOP) between its G.fast solution and the G.fast solution used in Swisscom's DPUs.

As with most of the broadband technologies, IOP starts at the chipset level, and for Metanoia, like for other chipset vendors. Reaching full IOP with our G.fast chip has been critical to us as a company, as it is also to System companies and Operators. Operators see IOP as a corner stone to their network deployment, and they are eager to deploy equipment, like G.fast Distribution Point Units (DPUs) and Gateway/SFPs using different chipsets, and to be able to operate together on their Network.

"Thanks to an G.fast SFP module developed by Metanoia and Huawei, we will be able to upgrade our Internet-Box plus or standard router in the field to G.fast. It is a key element of our current deployment strategy, that our customers can benefit quickly and easily of the new high speeds possible of the G.fast technology on copper networks using our existing routers." said Nicolas STEFANI, Router development expert at Swisscom.

Metanoia G.fast technology is based on its new single device, the MT-G5321, which can be embedded into an SFP unit and plug into any existing or future Home Gateways, which has an SFP cage. Form factor, Low power, below 2W as per MSA requirement at 85oC, when combined with Performances make it the right technology specifically for an SFP solution.

Metanoia's CEO, CT WU added, "IOP is important to Metanoia, and reason we have been putting significant efforts into it. Bringing the first interoperable G.fast SFP to the market that can be used with deployed Gateways is beneficial to Operators and achieving full IOP with Broadcom allows Operators to benefit from that effort".


Metanoia will participate in the 16th Annual Broadband World Forum 2016 (BBWF 2016) in London, UK. Metanoia will be demonstrating its latest G.fast solution, including its SFP, in a real network environment as well as the world's smallest VDSL2 SFP. Please come to visit us at the BBWF 2016 (Booth E12) and on the IOP Pavilion.

G.fast News

I’m still working through remarkable presentations from the Broadband Forum events. Michael Weissman, Bernd Hesse and team did a remarkable job choosing the speakers. http://bit.ly/BBFBASE

Deutsche Telecom: 35b Supervectoring Delayed to 2019 http://bit.ly/35blater
Broadcom is now over 3 years late. DT briefed German reporters after their financial call and revealed 35b was now delayed until 2019. 35b should deliver 200+ meg downloads 500-600 meters, a crucial tool for DT, which is losing share to cable. Cable now covers about 70% of Germany and is expanding. DT now only offers 50-100 megabit DSL while cable is often 400 megabits, going to a gigabit. 

The problem is software; the hardware is shipping and supposedly will work. DT says 35b is not ready to turn on. Broadcom in 2015 said 35b was in "production" in the press release below. Alcatel in early 2016 said to expect complete systems very soon. "35g is very similar to 17a so there should be little delay."

Broadcom's problems are leading major telcos and vendors to have a plan B, using Sckipio G.fast. DT itself is planning extensive G.fast deployments in 2019, mostly in apartment buildings. http://bit.ly/35blater

Gigabit 100 Meters - Unless the Wires are Lousy http://bit.ly/gflousy
Speeds are fine, "Unless there's a line problem." I've been reporting for three years that ~10% of lines have problems. In the chart by Rami Verbin of Sckipio, he finds G.fast goes ~130 meters on good lines. Poor lines have about half the reach. 

His chart roughly matches the reports from Swisscom, Belgacom, and England for both G.fast & vectored DSL. The 10% with problems can cause the majority of the line-related complaints to support. The angry customers drive up cost.

Rami's solution to reach the gigabit is bonding, supported on the Sckipio chips. Verbin made some additional points:

  • 4 gigabits is possible by bonding two decent 2 gigabit lines.
  • Even in a service from remote cabinets, ~25% are close enough to get a full gigabit."
  • cDTA and iDTA are practical ways to deliver much higher upstream by switching some bandwidth from downstream to upstream only when needed.
  • 35B will probably be similar but Deutsche Telecom doesn't expect to deploy until 2019. http://bit.ly/gflousy

AT&T Wants Coax 2-5 Gigabit G.fast. Very Soon. http://bit.ly/ATTCoax
AT&T faces intense competition from cable, talking about 10 gigabits in both directions. (Cable will only be 1 gig down, ~100 meg up, until ~2021.) AT&T wants something to brag about as well.

AT&T gained millions of lines of coax as part of the DirecTV deal. Alcatel and Huawei are leading the development of G.mgfast. That uses 424 MHz, full duplex, to achieve ~2.5 gigabits in both directions. The reach on telco twisted pair is only about 30 meters. On coax, those speeds can probably extend far enough to service most apartment buildings. Using 848 MHz, speeds can reach 5 gigabits. The ITU standards group has been aiming for 2019-2020 for G.mgfast, too slow for AT&T's marketers. David Titus wants a high-speed standard for coax "early in 2018." He believes that is "doable."http://bit.ly/ATTCoax
