Fiber Optic Tips APC vs UPC Optical Connectors Perhaps the most frequent call we get from distressed customers pertains to APC and UPC or PC connectors. Let's define these terms first. APC stands for Angle Polished Connector. It is the green connector in the picture below. Note that the tip of the white ceramic has an angle on it. This angle prevents backreflections which will seriously degrade the performance of any analog fiber optic system, such as CATV and Satellite. UPC stands for Ultra-Physical Contact and PC stands for Physical Contact. The blue connector in the picture is a UPC connector. You can see that its end looks flat and at zero angle. In fact it has a slightly curves end face so that the fiber cores make contact first.
