Twisted pair with pvc insulation is good for 300 volts.

There has to be some metric other than just watts. 190 volts at ~~ 1/2 amp gets
you your 100 watts, but so does 190 amps at a 1/2 volt.
More volts means you can use smaller diameter wire, but more volts means you
need more insulation.

I'm looking at strand mounted OLT's. One of the powering options is RFT-V
which is a nominal 190VDC over twisted pair. I have 0% familiarity with it.
I found a white paper from Commscope saying that the max is 100W, and at 3000
meters your 100W becomes 60W effective power due to voltage drop. Is that a
fair rule of thumb?
Hey Chuck, didn't you have an excel calculator for this?
