For just $5 or $10 more, it's a no-brainer to go 10G and let GPON fade away. A world class telco tells me they will switch in 2019. Xavier Niel's Salt tells me customers love the 10G. Poland's Inea is ready to serve 30,000 homes. (below) Jeremy Chelot's Community fibre has reached almost as many in London and has raised 40 million £. Hong Kong Broadband is well ahead. Frontier in the U.S. is upgrading some of the Verizon BPON lines they bought.
AT&T has supported an Open Source 10G ONT and done extensive trials. If they deploy, that could be five million lines/year. Adtran is making a big push to displace Nokia. (pr below) Back in August, they told me 10G was a no-brainer. They now are proclaiming that to the world at BBWF. Huawei has confirmed to me how close the prices are to volume buyers. Nokia is staying mum, as they do so often these days.
Tom Rutledge, the CEO of Charter, has 25 million cable customers, nearly all of whom can get a gigabit. Comcast has 30 million. That's why AT&T is building gigabit fibre at the fastest pace in the western world; cable is killing them in the old DSL areas. Rutledge is telling Wall Street he's not worried about telco gigabits. "Fibre is going to 10 gigabit upstream and down." Soon.
