Verizon Will Avoid G.Fast, Stick to Fiber Over the years a lot of hype has been focused on G.Fast, a technology that lets users deliver significantly faster DSL speeds over copper. The technology uses vectoring to reduce the cross-talk interference that traditionally plagues copper lines, helping companies reduce line noise and boost DSL speeds over short distances. It's of most benefit in terms of apartment complexes or multiple dwelling units, bridging connectivity from the street to individual units using traditional copper.

And while some telcos like Frontier have slowly started using the technology in this fashion, Verizon this week proclaimed it would be skipping the tech and sticking with more reliable fiber. “The strategy we’re using today is fiber all the way to the living unit,” Verizon Director of Networking planning Vincent O’Byrne told attendees of an industry event this week. “There’s some small percentage that we use fiber to the building and then copper inside the building itself, but because we have two vendors on BPON and on GPON meant in those units we had 8 types of different MDU units.” “Our strategy for G.Fast is not to deploy it,” O’Byrne said bluntly. One of the major reasons for Verizon's skepticism surrounding G.Fast is the problems the company had using VDSL2 over copper to help bridge FiOS connectivity in apartment buildings and MDUs. At the end of the day, G.Fast still runs into the same problems with longer loop lengths degrading speed, and Verizon also found consistent interoperability issues with VDSL2 gear. “We ended up in a situation where the 13 units of VDSL2 were going end of life as well as lower speed down the surrounding Fios network, which could get up to 1 Gbps,” O’Byrne said. “With G.fast we see ourselves potentially being in the same situation five years from now where we would have to replace the same thing.” “We ended up in a situation where the 13 units of VDSL2 were going end of life as well as lower speed down the surrounding Fios network, which could get up to 1 Gbps,” O’Byrne said. “With G.fast we see ourselves potentially being in the same situation five years from now where we would have to replace the same thing.”

not wasting time and money on m&a and aol'like nonsense.



i love reading how Verizon is going all in on it's original business plan,

instead of getting distracted by shiny objects in unfamiliar industries.

Hopefully this doubling down means the network transition project will continue onward and bring FiOS to the gaps in coverage that exist within equipped areas. BiggA

2 recommendations BiggA Premium Member Would have made sense for MDUs It would have made sense, but no, leave the ones with VDSL FiOS stuck at 25 or 50mbps or whatever they are.



And also, what is so hard to support about them? Maybe if they did more of them, it would make more sense.



And, they could actually upgrade copper areas to VDSL2 and ADSL2+, but no, they stick with old ADSL capped at 7mbps....
