Typical connectors are rated for 500–1,000 mating cycles. The other parameter is return loss, with grades from 1 (best) to 5 (worst).Ī variety of optical fiber connectors are available, but SC and LC connectors are the most common types of connectors on the market. The standard gives five grades for insertion loss from A (best) to D (worst), and M for multimode. 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. These connectors find applications in telecommunications, data centers, and industrial settings. Industry standards ensure compatibility among different connector types and manufacturers.

Optical fiber connectors are categorized into single-mode and multimode types based on their distinct characteristics. Quality connectors lose very little light due to reflection or misalignment of the fibers. These connectors include components such as ferrules and alignment sleeves for precise fiber alignment. In all, about 100 different types of fiber optic connectors have been introduced to the market. They come in various types like SC, LC, ST, and MTP, each designed for specific applications.
