96 ports promised and even more sought. Burri of Swisscom confirmed he has a similar unit. Update, 7/10. Huawei has now confirmed they are shipping 96 ports. I had guessed it was Huawei in the original. end update. G.fast was designed for local distribution points serving up to 16 homes, of which British Telecom has about 4M. These are very close to the subscriber. G.fast from local distribution points delivers 500-800 megabits today and well over a gigabit very soon. The BT plans changed, going to the (much fewer) existing cabinets.
Many buildings have more than 16 apartments. Many cabinets have hundreds.

Officially, it's not G.fast but they aren't stupid. When they run "fibre to your driveway," they will be within 100 meters of most people. That allows 500-800 megabits of G.fast today and over a gigabit as amendments 2 & 3 are delivered next year. Presumably, the final announcement is waiting for a government plan to deal with the over $10B in cost overruns.

Great 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 G.fast, 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 Google.hk.

Shipment claims are so far ahead of sales that need an explanation. Nokia is proud they won the G.fast order from Frontier in Connecticut, a U.S. company with over 4M DSL & fiber subscribers at the end of Q1. They gave no details of when, where, or how many, so it wasn't worth a headline. (PR below)
The interesting thing in the release is the claim they've shipped, "30 million vectoring lines." I'd be surprised to discover that even 10% of those are actually deploying vectoring. Similarly, Adtran claims 10M vectored. (PR below) There are remarkably few vectored lines in service. The claimed vectored ports are probably 10x or more the number of actual vectored lines.
There just aren't many homes connected with vectoring.

The right (straight) cable allows remarkable choices. Bill Bittencourt startled the G.fast Summit with new results from the lab and the field. They said it couldn't be done, but Calix customers are proving it is possible to use multiple DSLAMs. Instead of being limited to 16-24 G.fast customers, that can be doubled and possibly tripled. In early testing, the second DSLAM resulted in less than a 2% loss. Many North American buildings have straight cable – otherwise known as CAT1 or “station wiring” – from a distribution point to each unit. Geoff Burke explains, "In essence, what this means is that typical MDUs have insulated wiring from the Distribution Point to the unit, which greatly minimizes cross talk and loss.

Especially in the U.S. and Canada, there's a stampede to reach MDU customers with five hundred megabits to a gigabit. If you want to win customers in large buildings, it's becoming a no-brainer to go to G.fast - today. About six months ago, I predicted that would be the trend, but until Calix shared their customer details, I hadn't seen evidence I was right.
There are ~30 announced G.fast deployments worldwide, so I was startled when Calix told me they have about 90 customers in active deployment. I've known the Calix people for a decade or more, and don't doubt their claim. Some undoubtedly are just a building or three, but I know others, including Century/Qwest, are far beyond that stage. Geoff Burke writes, "There is no doubt that we are seeing a major shift from promising 'pilot' technology to live commercial deployments. Calix alone has now over 90 commercial deployed customers and increasing with a dozen new customers every month. They are installing in both low-rise to high-rise MDUs, from towns to the largest cities, Business MTUs and parks and even campus environments such as universities."
74% are in the U.S., 12% in Canada, 9% in AustralAsiaPac and 5% in the rest of the world.
