Lincoln Lavoie sees "cross chipset interoperability and performance at all levels including device software for management and control." Gear with chips from Broadcom, Metanoia, and Sckipio are working with each other at a good speed, usually 600 megabits or higher. EXFO and Viavi testers also passed.
He adds, "Gfast testing has already been more rigorous than any previous certification testing and we are testing individual features more deeply than we have on any previous technology."
"Interoperability" is considered to mean working reasonably together, not necessarily at maximum performance levels. While first generation G.fast is defined to about one gigabit, interoperability testing does not run at those speeds.
There is so much in the 300 pages of the G.fast standard only a fraction of functions can be tested. Many will never be implemented. The standards were put together by two dozen respected engineers, all of whom seem to have had ideas about how things can be done better. Nearly all those ideas made it into the standard.
With British Telecom soon to reach 1,000,000 homes passed, there's no question it works.

Three-fold jump in Gfast certifications aligns with service provider momentum
Now at 24 from the initial 7, with ADTRAN, EXFO and Viavi joining the systems vendor list
Fremont, California, 6 September 2017. The Broadband Forum announced today that the number of certified-interoperable Gfast solutions has jumped from 7 to 24 in less than three months, as mass deployment of the ultrafast access technology builds.
ADTRAN, EXFO and Viavi have been added to the list of companies whose products have successfully completed the Gfast certification program from the Broadband Forum and University of New Hampshire InterOperability Laboratory (UNH-IOL).
“From recent leading provider deployment announcements and analyst predictions, there is no doubt that Gfast is gathering momentum with the value of certified-interoperable systems well- recognized as key for mass-market provisioning of ultrafast broadband,” said Robin Mersh, CEO at the Broadband Forum. “Having only announced the first Gfast certification results less than three months ago, it’s great to see the certification program’s rapid and measurable progress.”
Lincoln Lavoie, Senior Engineer, Broadband Technologies, at UNH-IOL, said: “The certification program is driving cross chipset interoperability and performance at all levels including device software for management and control. Gfast testing has already been more rigorous than any previous certification testing and we are testing individual features more deeply than we have on any previous technology.”
ADTRAN, EXFO and Viavi join ARRIS, Calix, Huawei, Metanoia, Nokia and Technicolor, which were the first companies to achieve device certification supported by chip manufacturers Broadcom, Metanoia and Sckipio.
The Gfast certification is in accordance with the Forum’s IR-337 certification test specification. Testing is carried out at the Forum’s approved Gfast test laboratory at the UNH-IOL. The growing list of certified devices is available on the Forum’s Gfast certification page.
