In fact if OR mounted the ONT, preferably in the casing, on the plywood board as in the photo, I could easily put a 25 mm hole for the fibre. The fibre could come out through the knockout on the back box of the NTE5 and drop down behind the ply. The psu lead could enter the same way.

One question, why most, if not all of the install photos I've seen, have the ONT surface mounted without the casing?

Cheers!

Casing - do you mean the larger enclosure that housed the once Battery Backup Unit (BBU)? If so that was discontinued in 2019.

Now you just get the bare ONT, either Nokia or Huawei depending on the headend.

No, I was thinking of the one candlerb referred to:

Difference there is Greenfield (new housing developments, pre-cabled by the developer - backboxes installed the walls etc) vs Brownfield (everything else - just drill a hole through the wall and poke the fibre through).

Greenfield gets the casing and Brownfield don't.

Interesting.

I will have to find out what a new housing development just up the road gets. The fifteen houses are being built on the site of a demolish convent, so planning wise Brownfield.

Yes not so much from a planning perspective per se, but more from the perspective of new plots, land and developments which have no existing BT/Openreach service connection. In Openreach terminology those 15 new houses would be considered a greenfield site.

Not always. A recent FTTPoD install (as usual something of a saga) was fitted with a Huawei 1+0 ONT in one of the new cases, it got removed as the ONT was then placed in a larger lockable enclosure with other equipment.

Precisely there is zero reason for that case, unless its covering a recessed back box where the incoming fibre enters. So you basically can chuck it in the bin unless you have a double backbox pre-fitted with loops of the incoming fibre within it to hide. Otherwise it serves no useful purpose.

In a typical existing premises / brownfield install they will take the fibre through the wall and take it to where you want the ONT fitted (within reason). The ONT will simply be surface mounted, unless of course the home owner has gone to the trouble of chasing out their wall or cutting out the plasterboard to fit a back box....
