I’ve come across various articles online that explain the differences between APC and UPC, where the former has an angled polish and the latter is a straight “cut”.
Some of them explain that UPC and PC are very similar but that UPC seems to be an evolution of PC with a smaller mating surface.
However, other material I found suggested that UPC has a slight bevel compared to PC.
Now I am wondering, am I able to use the two interchangeably or will I ruin the connectors if I use, say, a female PC connector with a male UPC or vice-versa? Does the answer to that question also apply for transceivers?
