How to identify the end face of an optical cable
All fiber patch cable connectors have a ferrule end face where the fiber strand is centered to allow it to mate with another fiber assembly or attach directly to a piece of equipment. Contaminated fiber end faces can cause signal loss and reflections that degrade network. Endface inspection is one of the most critical steps in fiber connector quality control. Even a small dust particle or scratch on the endface can increase insertion loss, reduce return loss, and introduce random link instability. Mainstream Fiber Connectors Types and Applications Definition: MPO connectors are high-density, multi-fiber connectors designed to accommodate. The detection and cleaning of connector end faces is a very important task in the field of optical communication, as contamination of device end faces can cause attenuation of optical signals and affect communication quality.
