is not exactly true. The unused pairs in Ethernet cable serve a purpose. You cannot device the cable into two xmit/receive pairs, recode them and use them for two independent digital signals. An unused pair can be used for DC current POE but not another digital (and I presume analog) signal just by splitting the pairs. You don't even cut and splice Ethernet if the cable is too short for your purposes. There are strict standards even so far as how much untwisted length is permitted at terminations.
first off the question: While running a cat 5e wire for iptv can the pairs be split to be used for 2 jacks instead of one?
I know that to run ethernet only 2 pairs are used freeing up 2 pairs of wires
me (and many on my crew) being a cable/internet installers have used this handy trick many times but the boss has recently brought it to our attention he does not believe in this trick and fears crosstalk will cause iptv (pixeling/freezing) and internet connectivity related issues and thereby forbid wiring in this way until/if proof is shown that it is ok
and for anyone who wonders why not just run 2 wires we usually do this in apts where the cat5 is tucked under the baseboard and only 1 wire will fit loop to 1 tv then continue the loop to a 2nd or in cases where someone has a computer right next to their iptv 1 wire 1 run or finially in prebuilt homes where cat5 has been prewired to the 3rd story and the modem needs to be placed in the basement but the homeowner wants both internet and phone in a room (2 pair internet 1 pair phone) etc etc
So if anyone has any insight into why this trick is either a disaster waiting to happen or a perfectly safe shortcut of sorts it would be greatly appreciated
