Measurements of these parameters are now defined in IEC standard 61753-1. Performance of optical fiber connectors can be quantified by insertion loss and return loss. The resulting glass-to-glass or plastic-to-plastic contact eliminates signal losses that would be caused by an air gap between the joined fibers. Most optical fiber connectors are spring-loaded, so the fiber faces are pressed together when the connectors are mated. Optical fiber connectors are used in telephone exchanges, for customer premises wiring, and in outside plant applications to connect equipment and fiber-optic cables, or to cross-connect cables. However, the assembly and polishing operations involved can be performed in the field, for example, to terminate long runs at a patch panel. Due to the polishing and tuning procedures that may be incorporated into optical connector manufacturing, connectors are often assembled onto optical fiber in a supplier's manufacturing facility. Optical fiber connectors are used to join optical fibers where a connect/disconnect capability is required. In all, about 100 different types of fiber optic connectors have been introduced to the market. Better connectors lose very little light due to reflection or misalignment of the fibers. The connectors mechanically couple and align the cores of fibers so light can pass. LC (top) and ST (bottom) optical fiber connectors, both with protective caps in placeĪn optical fiber connector joins optical fibers, and enables quicker connection and disconnection than splicing.
