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.
