Fiber-optic connectors endface geometry and their impact on connector performance

In today´s network transmission rates and higher power carrying, fiber connector reliability and quality are the critical points in network performance. Network failures, which are caused by weak performance of connectors, can be eliminated by giving consideration to a few points surrounding connector quality. Teicordia has developed specifications for network components. GR-326-CORE define, among other things, optical and geometry performance: insertion loss (LL), reflectance loss (RL), radius of curvature, fiber high and apex offset. The most critical in fiber connector assembly process is polishing stage. Errors that occur during this process directly affect connector performance.
