Or how about we turn your question around, how can you prove it isn't?
Granted G.fast deployment has slowed right up, has it totally stopped no.
Yes it has.
The G.Fast rollout has been officially paused till at least April 2021.
It may never resume.
There have been no new G.Fast areas announced since the end of 2018 and i haven't seen or heard of a single pod being installed in 2020.
They use the exact same vented pods for VDSL2 expansion.
The VDSL2 pods contain a Huawei MA5818 DSLAM.
It can hold 4 x 64 port line cards and has a 256 line capacity.
OpenReach also deploy Subtended Head-Ends (mini OLT's) in the exact same vented pods, though this is much rarer.
Andrew did a recent news article on this site with pictures of a Nokia S.H.E inside 1 of these pods.
The unvented pods connected to PCP's are for additional IDC blocks and are often installed for additional tie cables after VDSL capacity has been added.
The vast majority of these pods that are installed now are VDSL Sidepods, and even show up on codelook as "VDSL Sidepod" after they have been installed.
A small amount of these pods installed now will be Subtended Head-Ends.
None of them are for G.Fast.
