Nope, Pockethernet.

Many of the basic testers use DC voltage to test the lines, so they wouldn't pass through the inserter to test those lines.

In theory you can capacitively couple ethernet but I have never tried it.

I'm looking for a basic-level Ethernet cable tester that only checks the wiremap, gives pass/fail and preferably is <$100 and has a simple TDR. It must survive Canopy 30V PoE voltage as it seems that many of the dead testers that we have in a pile are due to field techs plugging them into live lines. Monoprice $80 tester is OK but definitely does not survive the live lines. A test I'm considering is soldering ~15V zener diodes inside a unit to trigger a PSU's short protection before frying the cable tester...
