Fiber connectors join optical fibers where a connect/disconnect capability is required and enables an easier, quicker termination or connection. Typical connectors are rated for 500-1000 mating cycles and different connectors are required for multi and single-mode fibers. The main differences among types of connectors are dimensions and methods of mechanical coupling. The most common connection types are SC (Standard Connector), ST (Straight Tip), LC (Lucent Connector) and FC (Ferrule Connector). SC, ST, and FC connectors share the same ferrule sizes allowing them to be joined with each other using hybrid mating adapters. LC connectors are smaller and used for high density connectivity. For an optical fiber connector to be considered the best, it needs to have low insertion loss, low cost, and be easy to terminate.
