A question about FTTP installation

H3len1707 — Thu, 11 Jun 2026 21:40:20 GMT

Hello Folks,

We're about to switch to Plusnet and FTTP.

We currently have FTTC and presumably copper wire from the cabinet to our house.

My question is, how much physical disruption will this involve?

Currently the phone line comes into the garage and through a hole into the house. Can the fibre cable simply use the same route, or will there be more drilling?

Any information much appreciated.

Thanks in anticipation.

@H3len1707

Have a look at the following

https://www.openreach.com/help-and-support/full-fibre-broadband-installation-checklist#accordion-b43490109a-item-56113228ba

An external box (CSP) is required and an internal box (ONT). The latter needs a power source. Your router connects via ethernet cable.

Thre is a certain leeway as to where the CSP and ONT are located. You speak to the engineer on the day, tell then what you'd like or where you plan to have the router and then agree a route for the fibre.

Thanks Brian.

The site you pointed me to mentions "Both should be positioned close together and near the double power sockets you prepared earlier". Trouble is, there isn't a double power socket either in the garage or in the room where the router needs to be...

I'm attaching an image of the 'box' I believe brings in the current copper wire from a manhole in the road. Will this become redundant and have to be replaced by the CSP?

I'm beginning to wish I didn't need FTTP, but as I understand it, there's no other option once BT switches off the copper network. Is that correct?

Thanks for your input.

@H3len1707 The ONT and router do not need to be 'positioned close together and near the double power sockets you prepared earlier".' So long as you can run an Ethernet cable between them, they can be up to ~100m apart.

Thanks John.

So, if I understand this correctly, there needs to be a box on the wall outside and another box on the wall inside. How are they connected? And how is the outside one connected to the cabinet?

Also, is the thing in the image I posted relevant?

I'm finding this all very confusing...

Thanks for your help.

Correct, @H3len1707 . the box on the outside is connected by fibre cable to a CBT (Connecterised Block Terminal) in/on either the underground chamber - for underground feeds, or the top of telegraph poles - for overhead feeds, and the outside one is connected to the inside one with another cable.

FTTP does not go anywhere near the cabinet, it runs direct to a head-end in an exchange.

Don't know what your picture shows, it has to be released by a mod/Super User before it is visible to the forum - I'll request its release.

Thanks again John, you're helping a lot.

So when I left the house not so long ago and found two openreach engineers working in a manhole, presumably they were connecting cables from the exchange, not from the cabinet across the road?

Correct, @H3len1707 if the work was associated with FTTP installation, it may not have been.
