  • 4 or 6 utp 5e in a trench

    I need to pass 4 utp 5 cables between my garage ( computer shop) and my house, I need 4 of them because they are 4 different subnets, I already have 2 in pipe with a distance of 12 inch. between the pipes, but this time I would like to put 4 or 6 of them in the same tubing, do you thing I will have crosstalk between them? It’s a distance of 40’ feet

    IMHO, over 40 feet it is unlikely to be an issue (think of the bundles of cables around comms rooms of large buildings, for example. Earthing is going to be more of an issue -- IIRC you may have problems if the garage is separately earthed from the building, but I cannot remember the exact problem.

    Thank you,

      If you have a look in a Comms cabinet and follow the bundles of often 50+ cables back into the ceiling (or floor) and then off to their destinations I think that will answer your question. In my experience with cabling, I have never has crosstalk issues with bundles of up to 12 cables over 75 metres and 6 cables over a 90 metre distance.
