The number of G.Fast products certified by the Broadband Forum has grown over the summer, with 24 solutions now making the grade.
The industry body announced details of first six products to be certified by its partner, the University of New Hampshire Interoperability Laboratory (UNH-IOL), in June.
Technology from ADTRAN, EXFO and Viavi has now joined that from the likes of Huawei and Nokia.
The certification programme is designed to reduce the time that operators need to spend on testing the emerging technology.
Lincoln Lavoie, Senior Engineer, Broadband Technologies at UNH-IOL, said: “G.Fast 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.”
Deutsche Telekom said in July that it had started lab trials of the latest G.Fast technology as it looks to boost the speed and performance of its FTTC network.
According to an October 2016 report from Ovum, almost 29 million households will be served by G.Fast by 2021.
However, the debate over whether operators should be investing in the souped-up copper technology, rather than focusing on pure fibre, continues.
Broadband Forum CEO Robin Mersh said: “From recent leading provider deployment announcements and analyst predictions, there is no doubt that G.Fast is gathering momentum with the value of certified-interoperable systems well-recognised as key for mass-market provisioning of ultrafast broadband.
“Having only announced the first G.Fast certification results less than three months ago, it’s great to see the certification program’s rapid and measurable progress.”
