Can Fibre exit through the rear of the CSP?

[AndyCM]

I’m anticipating requesting an FTTP install to replace my current copper so thinking ahead about the practicalities! 

My current copper wire comes to the front of the house through BT underground ducting, up a short section of capping rising about 15 inches up the outside wall and then passes through a hole drilled (directly) from outside to inside into a single gang metal back box for the existing BT master socket.  All pretty straightforward!

I’ve read through other user’s questions but could not find a definitive answer to my question – can the “internal” section of fibre leave the CSP through the BACK of the CSP or does it have to physically exit from a side or the bottom? 

If the fibre CAN exit through the BACK of the CSP, presumably the CSP outlet can be located over the current hole in the wall, on the outside of the property, and the fibre use the same hole through the wall in place of the copper?  There’s enough room for the ONT right next to the existing back box for the fibre to make an easy loop to connect.

Is the ‘old’ copper wire left in place or can it be removed/cut back.

Can anyone with this detailed knowledge help me prepare for the great day - many thanks.

The CSP Openreach use is this one

There are access holes in the rear ( punch out type ) so a cable can enter here ,  in fact on newsites where FTTP is available from the outset,  it’s the usual method of cable entry for the internal Ezibend cable so no cable is visible , but obviously in your case the capping 25 is already fixed in place ,  as is the access hole into the property,  you probably have a cover 101a on top of your capping 25 and the CSP can directly replace that , to give an inter-grated look , but the hole in the CSP and the hole through the wall may not exactly align once the CSP is placed  on top of the capping , but chances are the tech should be able to install in the way you want .

Thank you iniltous; you've made everything crystal clear and given me the detail I sought.  As the CSP can be fitted over the existing hole in the wall, the copper wire will need to be pulled back out of the way; is it usual practice to leave a cut/sealed end in the CSP?

Thank you again.

Yeah, there is a punch out hole on the CSP.

Issue is they sit flush against the wall so trying to drill out to exactly where the hole in the wall will meet the hole in the CSP is a challenge in itself.

New Builds are easier as the Lead In is usually left swinging in the breeze before the Duct even goes in so it’s fairly easy to line that and the CSP up with the Lead In.

You’ll struggle to find an Openreach Engineer willing to drill from the outside in.

As far as the existing copper cable being removed, I don’t know what the official procedure is , once the FTTP is in and working there shouldn’t be any reason why the copper pair would ever  be reused so removing it ( to make the access hole more accessible) will probably be done , I doubt they wouldn’t leave it coiled in the CSP , more likely it’s simply cut before the CSP and pushed back behind the capping .

The copper wire will be cut back as required as the hole will most likely have to be enlarged.

Thanks 36ULW, but fortunately I do have an existing hole-through-the-wall through which my copper wire enters.  The question then is whether the CSP can be fixed in a suitable position for the Ezibend fibre to exit the punch out hole  you mention and then re-use the same hole-through-the- wall.  Have to wait for the Engineer's visit to look in detail

[AndyCM]

Thanks iniltous, sounds like cutting short and pushing behind the capping will be the simplest solution!

Thank you pippincp; I've lived here for 33 years and never once removed the 101A to see what's underneath!  Guess I'm about to find out!
