Full Fibre External cable from CSP to ONT?

troy45 — Wed, 18 Dec 2024 21:39:27 GMT

I’ve booked to get upgraded to full fibre next month. Currently my landline/copper fibre connection comes in from the pole, straight down to an upstairs bedroom at the front of the house. My router is also upstairs but at the back of the house connected by an internal cable run I put in.

Expect the CSP box will be installed at the front of the house, is it possible that I can have the ONT box upstairs at the rear of the house (2-bed semi) with external cable run around the outside of the house connecting CSP to ONT?

Failing that I’d need the OSP box upstairs at front of house so I can run an Ethernet cable internally to the rear bedroom where the router lives. Running Ethernet cable from downstairs to upstairs would be very messy if even possible.

Any experience with this would be helpful, thanks

@troy45 Any external CSP must be installed at ground level, the installation engineer can not splice the Fibre in the CSP at height. It IS possible in some circumstances to install an internal CSP e.g in a loft BUT it must be fully boarded.

My router is also upstairs but at the back of the house connected by an internal cable run I put in.

If the cable is telephone cable, then that will be of no use, the cable from the ONT must be ethernet Cat5e or better.

Note that the ONT requires mains power to be within approx 1m

Thanks, that confirms one part then.

Would it still be an option for them to run cable back up the front of the house so the ONT can be upstairs also at the front of the house? It can go in the spare room where the current phone line comes in, they’ll have to work up there anyhow to bring the incoming line from the pole down to the CSP. Mains power is available there too.

I’m ok putting in an Ethernet cable to go from ONT to the router replacing the phone line I have now if they’re both upstairs but routing from downstairs to upstairs is a non-starter really

@troy45 the cable from the CSP to the ONT comes in precut lengths. Its designed to run internally and has a pre-attached plug for the ONT. So that cable is normally routed from the ONT through a hole drilled in the wall adjacent to the CSP and then spliced into the CSP.

You said: "routing from downstairs to upstairs is a non-starter really"

I assume you mean internally?

Would it be practical for you to have the ONT downstairs and run an external grade ethernet cable on the outside of your house from the ONT to the router instead?

There is this kit which is worth knowing about https://shop.premitel.uk/product/fibre-termination-point-relocation-kit/

I did find this Openreach document recently;

https://www.openreach.co.uk/cpportal/products/fibre-broadband/installation-options

not sure if it's valid but it mentions a premium installation service

I think the best way forward is for you to what dan has suggested.

fibre from pole, to your existing entry point at ground level, and then upgrade the existing cable (which you said you can do) to external cat5e or cat6/cat6a (note that proper cat 6a is a pita to use - its not very bendy).

@troy45

The fact is you won't know until the day of install. You speak to the engineer about what you want to do. In general terms if it's possible they'll work with you to do the install to your satisfaction.

If the ONT does end up at the from there's nothing stopping you from runnning an external ethernet cable from the front, round the back and then in at the desired location. You can get someone in to do this. Not the cheapest option but it is future proof.

The purpose of my post was advise that there is a kit available to extend the fibre cable between the CSP and ONT, not to adopt it's use.

Thanks all for the advice. I’m going to have to look at this more and possibly see if can discuss with Openreach ahead of the day of installation. I want this to be all up and running when it’s installed so need whatever Ethernet cabling I go with to be in place ahead of install date.

External routing may be an option but not one I’m keen on unless it’s just routed up the front of the house then I can go internal from there. Seems wrong to drill a hole for the fibre coming into the house then another one next to it for Ethernet coming straight out again 😕

"Seems wrong to drill a hole for the fibre coming into the house then another one next to it for Ethernet coming straight out again"

Do you mean having 2 holes?

Are you able to be there yourself when the installation is done? Maybe after the discussion with the installer, you could drill the hole for the fibre, but a bit bigger, so that both the fibre and ethernet cable can fit through the same hole?

Re: Full Fibre External cable from CSP to ONT?

troy45 — Thu, 19 Dec 2024 13:38:04 GMT

I’m wondering if it’s feasible to have the CSP inside, in the upstairs spare room along with the ONT. Current pole to house the cable comes across immediately above this room - would save taking the incoming fibre down to ground level, they still get to drill a hole in the wall and all the terminations to the box is done working inside rather than at height etc

That would seem to be a suitable compromise?

It is an oft asked question - see Internal CSP and fibre run through loft? : r/openreach and the many other results from a Goggle search.

On notable consideration is that the external "wire" does not comply with internal "wire" fire safety regs.

Cheers I’ll see what googling brings up on the subject

@troy45

I would consider it highly unlikely you'd get the CSP inside. It does happen occasionally but usually in a loft space. You won't be able to speak to OR prior to the install - it just doesn't happen unless they need to do a survey for potential obstructions to the actual install.

While the CSP has to be at ground level you might get luckly on the day with the engineer happy to run the incoming fibre cable round the back to the house. It has to come down to the CSP but could then go straight back up to come in where you'd like it to.

You just don't know.

troy45 — Thu, 19 Dec 2024 14:27:02 GMT

Fair enough - I’ll have to see how it works out on the day.

Unfortunately access at rear of the house isn’t very suitable for having the CSP at ground level due to back porch, where kitchen is etc.

Think I’ll get a longer Ethernet cable ready in case I end up with the worst case option - CSP downstairs, and rig that up temporarily while I work out the best way to do the final routing.

Re: Full Fibre External cable from CSP to ONT?

krusty — Thu, 19 Dec 2024 14:30:41 GMT

The main reason for a csp is to separate external cabling to internal - its easier to splice at the box outside then inside. I do think Troy should just upgrade the cable from the existing entrance point to his router to cat 5e/6.

@troy45

you said" Currently my landline/copper fibre connection comes in from the pole, straight down to an upstairs bedroom at the front of the house" the best route atm from what you said, is to upgrade this to cat5e/6

Slightly off at an angle alternative suggestion which will however potentially need some new equipment.

@troy45 The engineer will very likely want to install the CSP at the front of the house at ground level as noted above, with the internal kit straight through the wall from there which requires mains power.

The router can then be next to that (assuming you have enough space) and connected to whatever you need upstairs by various means.

Now I don't know the layout/size of your house or what connectivity/speed is required where, but a router downstairs will give normally some Wi-Fi coverage on both floors. Upstairs equipment can then be connected either directly to that or via some sort of network extension. That could be via WiFi to some sort of repeater, via LAN cable to a hub/repeater or directly cabled to just one device. And don't forget ethernet-over-mains connections (powerline) may help reach places where WiFi is poor. I believe that can even be used to connect to your router from the BT boxes.

Basically there are quite a few ways of doing it and you don't need to assume your router sits where it is now.

In the short term a suitable length of Cat5e cable draped around the house will probably keep you going until you decide on the best long-term solution. Maximum is around 100 metres so unless you live in a stately home it should do.

@troy45

My CSP is installed internally with the ONT in a different room on a different floor, and neither are in the loft.

It obviously needs agreement from the installer to locate it in an 'alternative' position, but it will mainly be down to how much 'spade work' you're prepared to undertake, see link below.

I've described my installation many times in these forums.
