In 2016, looked very promising.
Thousands worked at developing and deploying.
It wasn't enough. 
Most carriers are investing
in fiber or 5G instead.

Interop BBFGreat to have another chip source. Broadband Forum/University of New Hampshire has announced the first six products to pass their testing: ARRIS, Calix, Huawei, Metanoia, Nokia and Technicolor. (Below.) Nokia/Alcatel has long been #1 in DSL, with Huawei #2. Calix is coming on strong with, telling me they are adding so many new deployments they are about to have over one hundred customers in service. Technicolor and ARRIS/Pace/2Wire have long been top modem suppliers. But few in the industry know Metanoia, a Taiwanese chipmaker almost invisible when searching news, even on 

I'm apparently the only western reporter who has picked up on Metanoia and there is little on their website. The UNH testing is pretty intense; I doubt a chip could pass without doing most things right. They just shared with me some interesting news under embargo for a few days.


Interop testing is not just plugging things together and seeing if they work. This slide, from Frank Van der Putten and the Broadband Forum, shows you some of the testing done.

BBF Interop details

 Note that "Interoperability" as defined by the BBWF is a "Basic Minimum Level of Performance." It's currently set at 600 megabits. It does not mean chips or systems can be interchanged and not affect the results. One system may deliver 800 megabits and another 600 megabits and still be "interoperable" by this definition. 

Progress, but never fast enough.


First six Gfast certified products announced by Broadband Forum and UNH-IOL

Cross-device, cross-silicon interop demonstrates Gfast readiness for multi-vendor


The Hague, Netherlands, June 13 2017. The Broadband Forum today announced the first six

products to have successfully completed the Gfast certification program from the Forum and the

University of New Hampshire InterOperability Laboratory (UNH-IOL) – representing the next

important industry milestone by signalling market readiness for multi-vendor deployment.

The Gfast certification – carried out by the Broadband Forum’s approved Gfast test laboratory at the

UNH-IOL – is in accordance with the Forum’s IR-337 certification test specification, reducing costs

and accelerating time-to-revenue.

“Interoperable standardized Gfast technology is key because it underpins an ability to deliver next

generation ultrafast broadband at scale,” said Kevin Foster, General Manager, Architecture and

Innovation for BT. “Certification to the Broadband Forum’s Gfast requirements provides a known

level of confidence and will reduce test time for both network operators and their communication

provider customers.”

Listed alphabetically, ARRIS, Calix, Huawei, Metanoia, Nokia and Technicolor have worked with the

Broadband Forum and UNH-IOL to achieve the Gfast Device Certification.

The first set of certifications include products based on chipsets from Broadcom, Metanoia and

Sckipio, ensuring service providers will have choice of products, form factors, and features. The full

list of certified devices is available on the Forum’s public site Gfast certification page, which will

grow over the coming months, as additional certifications are achieved.

Lincoln Lavoie, Senior Engineer, Broadband Technologies at UNH-IOL, said: “The certification

represents an outstanding technical achievement with hundreds of rigorous tests of the stability,

functionality, control, and performance of Gfast systems and thousands of hours of close technical

collaboration over many months between the lab and all of the companies involved. The program’s

certification of these products has played a significant role in understanding and improving the

implementation of Gfast.”

Additionally, the UNH-IOL has made the Gfast test automation software commercially available,

which controls the Telebyte test and measurement equipment, enabling device manufacturers to

easily pre-test in their own labs and service providers to easily regression test software updates

from their suppliers.

Service providers worldwide are deploying Gfast to deliver gigabit faster over existing wiring,

bringing ultrafast broadband to more users, significantly reducing the cost of the final connection

into a home or business in comparison to an all-fiber deployment. The high throughput of Gfast also

increases customer satisfaction, reducing churn and driving revenue by opening new markets

where fiber delivery is impractical.

The announcement of the certification follows the continued success of UNH-IOL’s Gfast Chipset &

System Integrator Interoperability Plugfests – held in conjunction with the Broadband Forum –

where engineers from 12 member companies continued testing the latest advancements to the ITU-
T specifications and their Gfast products. Testing Service

The UNH-IOL Gfast Testing Services provides services for companies wishing to participate in the Broadband Forum Gfast Certification Program or Gfast Interoperability Plugfests. Testing can be completed on a variety of device types, including:

  • Reference Designs
  • DPU Devices
  • Home gateways and customer premises equipment (CPE)
  • chipsets
  • Hand-held testers and test tools
  • The Gfast Test Service leverages advanced test tools and our Test Sentinel automation platform to quickly and efficiently support the Gfast certification testing, shortening your test cycles and quickly progress your products to the certified status. Like all UNH-IOL testing services, Gfast testing is a collaborative test program that brings together industry leaders to foster quality, interoperable systems.

    Broadband Forum Launches Gfast Council

    Brings together service providers, equipment makers, silicon providers and software

    companies to accelerate the adoption of Gfast

    The Hague, Netherlands - June 13, 2017: The Broadband Forum today announced it has

    launched the Gfast Council to centralize and disseminate the expertise and experience of

    the Gfast market in order to facilitate the rapid deployment of Gfast implementations.

    Gfast is the new gigabit broadband access technology that deploys faster by extending fiber

    to existing wiring infrastructure. The Gfast Council will inform the market through events,

    white papers, use cases and other resources.

    “Consumers want ultrafast broadband speeds and they want them immediately. In many

    cases, Gfast offers service providers the best chance to meet this requirement,” said

    Broadband Forum CEO Robin Mersh. “The Council will be the center of expertise in Gfast

    and as such will work to show how Gfast fits into the bigger gigabit broadband picture

    covered by the Forum’s work.”

    The Council will also promote the Gfast Certification program, which today announced the

    first certified, interoperable products, to help accelerate the availability of interoperable

    solutions and expedite timely integration with service providers’ networks.

    “Gfast has become an essential tool for service providers,” said Michael Weissman, Chair of

    the Gfast Council. “The Gfast Council combines the collective intelligence of 150 members

    of the Broadband Forum to make the rollout of Gfast deployments faster and more


    Open to all Broadband Forum members, the Council will represent the Broadband Forum

    and the Gfast community Broadband Forum and at industry events such as today’s TNO

    Ultrafast broadband event in The Hague.

    The formation of the Gfast Council follows the creation of the NG-PON2 Council by the

    Forum earlier this year.
