I have to install a loopback for a DS3 data circuit. Is that just conect a piece of coax from transmit to receive on the LEC interface? thanks

Please advise. I say it is not pass/fail, but a characterization of the installed fiber. Power meter tests can be pass/fail. Very interested in the facts.
When testing Cat 5E cables, I rely on ACR (attentuation to cross talk ratio) the most. In my mind, it states the headroom I have between signal strength and noise. I try to get attenuation in the single digits too.
What numbers mean the most to you other pros??
Is there a web resource to verify the "market" price for cable, fiber and connecting hardware against a quote? Or do I just call a couple of distributors and compare?
