APC (green) connectors are polished at an 8° angle, pushing return loss above 60 dB. APC is required for GPON, RF-over-glass, and any link sensitive to back-reflection. Never mate APC to UPC — the air gap causes high loss and can damage end-faces.Are these patch cables tested before shipping?Yes. Every assembly is 100% factory tested for insertion loss (≤0.3 dB) and return loss before it ships, with test data available on request.Can I order a custom length or connector combination?Yes.
