I'm designing an internal CATV system distributed over OS2 SMF. The manufacturer of the fiber TX/RX requires APC connections into the equipment. Is it an acceptable practice to design the terminate the backbone for this on both sides into the enclosure using UPC ends and use a APC to UPC patch cable on both sides? I've heard different opinions about whether it needs to be APC to APC straight through vs utilziing APC ends into the equipment. I can't see why it would make a difference.

Thanks

You should check with the equipment manufacturer on this. Our CATV devices on campus require direct fusion splices all the way through to connectors and then spliced on SC-APC connectors. The reflections from even one UPC mated pair could cause issues.

My guess is that you'd be ok, but if there's any issue in the system they're going to point to the UPC connections first.
