What cables to pull through?


Recommended Posts

New build in progress.

 

Two rigid ducts buried in trench with drawstring, going from public footway to near new house. The ducts were put in to help future proof for
a) telecoms
b) fibre to the premises

No cable in them. What cable(s) to pull through before the end of the trench is backfilled? Nobody knows less than I do about these things.

Further, within the house want data points in each habitable room
plus TV points.

What wiring/cabling to use for
c) data points (previously someone suggested 3 Cat 6a cables per data point)
d) TV points

You won't be able to get the correct fiber that a future installer wants so you'll just need to leave that as an empty duct.

For telecoms now I'd get the provider (virgin or openreach) in now to do the installation. I actually signed up to a rolling one month virgin contract, they turned up a few days later and left a giant coil of cable in duct at our boundary, so I immediately cancelled the contract and then pulled that cable through the garden and house to the AV cupboard, then contacted them 6 months later to terminate and commission it.

 

Internal wiring I'd suggest 2x CAT6/CAT6A to each data point and up to 4 to the TV (especially and main TV location, for future proofing) 

I did cat6a everywhere but cat6 is more than likely fine.

 

Also consider pulling data cable to other useful places like the PV inverter, heating system, outdoor equipment, doorbell, CCTV camera points, etc.

No point pulling anything through as you don't know what the provider will want. And you can't normally share ducts. Just leave the draw ropes there. Fire a couple concrete blocks around the ends of the ducts so they are easier to locate and dig up in the future. Same for your own ducting.. I'm putting one all around the house and just leaving access points at each former of the house and draw rope in place. I'll be pulling an electric cable through one section for the car charger bit that's it for now.

We got an OR quote to pull cable from pole, duct across road and pull through the ducting we had laid to the plant room - was expensive so we got another contractor to trench across road to pole and pulled through our own 5 pair gel filled cable from TLC which meets the OR spec, left 10+m of cable coiled at foot of pole.

 

Paid for a new BT connection and when the OR guys came along they were more than happy to terminate the cable either end.

 

Only issue was we did not leave a spare draw cord in the duct and there is now fibre to home being laid in area (they are using whatever means OR currently use to each prem, duct or overhead) so not sure what we'll do when they roll past ours in a few weeks time.

Cobra duct rod?

 

At present they're only laying bare duct to boundary of premises or to base of OR pole (depending how house is currently served). We have a duct at bottom of the pole but it's a bit clogged with mud, I'm just concerned that they may not be able to loop a fibre back down it.

 

If I can catch them when they're digging then maybe I can get them to figure something out - however they're ripping through town at a fair pace at present !

Get some string, tie a plastic bag to it.

stuff it down the pipe.

go to the other end, put hoover in pipe and suck string through duct 

then pull in larger diameter rope

They'll use the gel-filled cable as the draw wire ;)

Wasn't planning on decommissioning it just yet :)

OK, obviously my advice is for when you go for the service alteration, assuming you then wouldn't want both.

TBH if you use the old hoover technique and some fishing line you can suck yourself a new draw wire in with ease.
