Full Fibre physical installation.

JayEeeCee — Tue, 12 Aug 2025 13:59:58 GMT

Good afternoon,

My house was built in 2002 and has ducting carrying the copper phone line into a cupboard under the stairs.

My house is a series of three which are close together, and I've found three BT rectangle covers outside the first house of our three (mine is the third).

The distance is around 30 feet I would say from said manhole to where our copper phone line terminates.

I've read up on the installation of full fibre and there is talk of connecting an ONT and drilling through the house but this would mean the ONT does not end up where the master socket is now - which is preferable. I also don't want this as would look awful as well.

Are Open Reach likely to use the existing ducting to bring the fibre to the same location as the master socket, which would be far easier than doing anything else given there is a road way between my house and the second house in our series of three?

Also, if I place the order to upgrade to full fibre, and Open Reach will not use the ducting, am I able to cancel the install at that stage?

TIA!

John

Your Fibre connection will follow exactly the same route as your current copper one.

I would just add, providing the duct is not blocked. They do get damaged by drives being laid etc.

@Baldrick1 They do, but how many U/G connection failures do we see around here?

There has been no work around the vicinity of where the BT manholes are and my house so hopefully it should be OK it sounds like.

These houses are on a small dead end road, with other houses surrounding and on the same road, and all the houses, road and infrastructure were built around the same time and so new then.

The neighbour of the first property, with the three small rectangle manholes out front, went for Virgin last year (albeit this is not a "Virgin cabled area" so LLU I suspect) and the engineers wanted to run the fibre exo at first. My neighbour declined and so they were "forced" to run it through the ducting - even though it's right outside the house!

@jab1 I've seen a fair number of underground duct problems reported on the forum in the past, in depends on the local area of course, where I live there are 5 houses at the end of a cul-de-sac and know that of the 4 houses recently ordering FTTP we have all experienced problems with blocked ducts. Mine was in the pavement, found by Openreach on the 9th April, finally fixed on the 1st of July after they missed two occasions when roadworks permission was granted. My next door neighbour has not been connected yet, duct probably blocked in the same area as mine so it will be dug up again. I did point out to the dig team that the neighbour's duct looked damaged but they said they would look at it but I don't believe they did anything. The other 2 houses had extra Openreach visits to clear ducts in the driveways which run down to the houses so probably silted up. The likely explanation for the pavement duct problems is mains gas pipes being installed some time after the houses were built wrecking the phone ducts in places.

So underground feeds can have problems, hopefully my fibre doesn't get damaged when more digging happens.🙄

@RealAleMadrid Agreed, they can have problems, but I wonder how many thousands they have done without?

@JayEeeCee

Have a look at the following.

https://www.broadbandchecker.btwholesale.com/#/ADSL

Full Fibre shows as WBC FTTP - what does it say to the right of this? Below the results window there should be a narrative about the FTTP install. What does this say?

The following picture is of an internal CSP attached to the old MS back box. In this case there was a duct all the way to the MS so this was used. If you look closely you'll see the fibre cable coiled behind the ONT.

At the time this install was done (in NI) it was stated these boxes were rarer than hens teeth.

@bmc Your pictures aren't showing (for me, anyway). See screenshot below:

JayEeeCee — Tue, 12 Aug 2025 17:10:09 GMT

To the right of WBC FTTP, it shows:

Featured Products	Downstream Line Rate(Mbps)	Upstream Line Rate (Mbps)	Downstream Range (Mbps)	Availability Date	FTTP Install Process
WBC FTTP	Upto 1000	Upto 220	--	Available	1 Stage

The narrative below shows:

Our records show the following FTTP network service information for these premises:-Single Dwelling Unit Residential UG premises served by 2.5 Inch plastic duct 56.

FTTP is available and a new ONT may be ordered.

Similar to jab1, I don't see the pictures where they should be but instead the picture jab1 posted.

@JayEeeCee I don't see you having any issues with your installation - unless they find something when they actually attempt it, but you won't know until they try.

bmc — Tue, 12 Aug 2025 18:20:39 GMT

@JayEeeCee

As stated, there appears to be no upfront problems with an install at your premises. Only on the day do you find out if this is true.

Apparently images now go through a moderation process before appearing so you might need to wait until tomorrow. I can see them but it's my post.

Some images - what do you see on my post referencing yours, @bmc ?

@jab1

Yesterday I saw an image of a grey triangle with a light orange infil in your post. Today there's two images, both the same.

If they don't appear some time today I'll re-post them as attachments.

@JayEeeCee

If the images don't appear by later today I'll re-post them as attachments. I'd save them so you can show them to any installer who states the CSP can't go indoors.

Is there a power source beside the MS? Two sockets ar required - one of the ONT and one for the router though you can locate this elsewhere.

this pdf from cerberusnetworks is quite useful as it has the external csp and internal one alongside with best practices on fibre drops too. Whilst for FoD quite alot of it is still useful

Are you sure you have an internal CSP? Your picture looks like it's just a so-called '1+0 ONT and Casing' which is just an enclosure design to cover and protect the ONT, connections to it and the incoming lead-in fibre. There would still need to be a CSP - the point at which the 'internal' and 'external' fibres are connected - or are you saying in your case this connection has been made inside this enclosure behind the ONT? Any chance of a pic?
