Green Connectors.
PC and APC connectors - are they exchangeable? Optical connectors are available in two versions, UPC and APC. UPC means Ultra Physical Contact, APC is the short for Angled Physical Contact. The difference consists in the polishing of the fibre end face. The end face in a UPC connector is flat, in an APC it is polished at an angle of 8 degrees. The fibre end faces polished at that angle prevent reflection of light from the interface between them, ensuring very low back reflection.
