Does this measure distance to short or open ?

Yes, it can measure distance to short and open.

Can this unit speed test a cable? 100mbs? 1000mbs?

Hi,network cable tester AT278 can not speed test a cable on 100mbs or 1000mbs.

Will this work with tracing cables that are in a POE switch without burning out the tester?

Manual does not recommend using this with POE

Does this test for cable signal? like 100 or 1000 mbit?

I think so, but I'm not 100% on that. I use mine mostly to check for fault types, and distance from end to fault location. You should read the spec and data sheets to see if that is listed.
