Is there a theorectical max length FTTP cable pole to house?

There will be approximately 65m of overhead cable from pole to house and then another 10m to CSP then 5m from CSP to ONT (I think I have the correct naming). I believe my pole is fed indirectly from another pole so that may add another 60m.

Will this setup cause any issues for an OpenReach or CityFibre install?

Thanks

Nope.

There are rules, for Openreach at least, for maximum span lengths. But these are in place in case of the span being too long, and the weight on the ‘curly-whirlies’ (which attach the cable to the ring head on the pole) being excessive.

In terms of the length of the fibre drop causing operational problems, nope.

As @Zarjaz says - limit is based on stress on curly-wurly and sag.

It must clear any highway by something like 5.5m (may be 5.9) and open land or footpaths by 3m.

My fibre runs around 50m from the distribution pole to carrier pole then just under 50m to the house and just clears the minimum height. There are longer poles that can be used to gain extra clearance.

The theoretical maximum length for a PON is 60km so if the pole run to your property starts outside the exchange with the OLT then the answer to your question could be around 59.75km.

But:
- Infrastructure operators generally keep their PONs much shorter than the maximum (and a maximum size PON can only practically be operated with no, or a very, very low split due to optical loss).
- I doubt that an infrastructure operator will devote a PON to a single customer, except in extreme circumstances.
- There is a limit of 20km radius difference between the closest and nearest ONT on the PON.
- All infrastructure operators will have their own limits on the length of pole run to a single property they will tolerate (which may very by circumstance).

Theoretical answers aren't always useful...

Thanks everyone for answers. As I am already getting FTTC via overhead cable I will just assume everything should be fine when I change to FTTP. If the maximum if 60km I assume a few extra metres over the average will not make much of difference

The maximum distance from CBT to house is 350m as that is the longest connectorised fibre dropwire cable that Openreach have available.

Since you are well under that, then it wont be a problem.

Great that is good news - hopefully CityFibre is similar also. Weird question but if there are fixed cable lengths you do not end up with masses of cable coiled up at the house end if you do not happen to be the correct distance away? I assume the only connector is at the pole end and they chop and meld the cable in the CSP as appropriate? Thanks

At least for Openreach, your guess is correct.
The connectorised end fits into the allocated port on the CBT (UG or OH) it is run to the location of the CSP, and the internal to external cable (which has a prefitted connector at the ONT end is run to the CSP.
In the CSP a metre or so slack is coiled up, and the two cables fusion spliced together. The lid of the CSP obscures all the ‘workings’ from view.

I am aware that at least one Altnet uses a cassette system at the property eaves to hide excess fibre, but these are a reasonably unobtrusive thing too

A neighbor at one of our houses measures 346m in a straight line from the CBT to their house according to google maps, they where listed as '1 Stage' install, they now have FTTP, it's strung along several poles then down a pole to ducting before it enters property. That looks damn tight if not impossible if it was a 350m cable, it is possible the CSP is on a outbuilding nearer to CBT, I've never looked, but if it actually goes to house could they have daisy chained it, or used a longer cable?

Who knows without seeing it.

Maybe a CSP between overhead and underground ?
