A device mounted on the end of a fiber optic cable, light source, receiver, or housing that mates to a similar device to couple light into and out of optical fibers.
A connector joins two fiber ends, or one fiber end and a light source or detector.
A mechanical or optical device that provides a demountable connection between two fibers or a fiber and a source or detector.
Hardware installed on fiber cable ends to provide cable attachment to a transmitter, receiver or other cable.
Usually a device that can be connected and disconnected repeatedly.
Numerous connector styles have been developed, each meant to offer better performance, easier and/or termination and lower cost.
Different connector types have different characteristics, different advantages and disadvantages, and different performance parameters. But all connectors have the same four basic components: ferrule, connector body, cable and coupling device. Each connector type has strong points, for example: ST connectors are a good choice for easy field installations; the FC connector has a floating ferrule that provides good mechanical isolation; the SC Connector offers excellent packing density and its push-pull design resists fiber end face contact damage during unmating and remating cycles.
Since fiber optic technology was introduced in the late 70s, numerous connector styles have been developed. Each new design was meant to offer better performance (less light loss and back reflection), easier and/or termination and lower cost.
