Cat5 twisted pair would have some loss as it’s a small conductor. Since PoE is DC and low voltage at that, it’s not going to interfere with the data. Ethernet uses only 2 pair of the 4 pair in standard cable.
We’ve used power injectors to power APs we stuck over the ceiling at work. the injectors were in the data closets and the APs were probably 50 feet away tops. Frankly I’d opt to pull a dedicated conductor of larger size if going that distance - I would simply extend the standard Tablo power supply conductor using heavier wire. THEN you are using THEIR PS, THEIR exact voltage and Ma rating, etc.
So my question, why risk voiding a warranty, power supply issues and so on when it would be easier to simply extend the Tablo power supply cord using - 18 ga. lamp cord!
Check the power requirements of the Tablo - check the output of the supply they send with the unit.
I’ve done PoE for network equipment I KNOW was able to run on it with the proper power injectors. You have to inject the power into the cable, then get it back off at the other end in the case of the Tablo since it’s not designed for it. If running a Cat5 why not wrap another conductor pair with it and do that. Low voltage will suffer more loss than running AC that distance.
I have to make such calculations all the time in my auto-electric business where I upgrade charging systems, install high-end stereo equipment and swap modern engines and fuel injection into older cars (talk about power requirements, EFI has a need for POWER and it’s got to be spotless clean power! An alternator with a bit too much ripple will screw up a lot of new EFI and computer systems. I had fun putting a later model EFI engine into my little Eagle. I had to do some math…
