Connectors are a type of fiber optic hardware that is installed on to the end of a fiber cable creating a cable assembly or pig-tail. Connectors are used to attach a cable assembly to a receiver, transmitter, transceiver, or other device.
Commonly used fiber optic connectors include:
- ST: Slotted bayonet type connector, long ferrule.
- FC: Screw-on connector.
- SC: Push/pull connector.
- LC: Like ST connector, but ferrule is half the size.
- MT-RJ: Connector for duplex fiber with both fibers in one ferrule.
- MU: Like SC connector, but ferrule is half the size.
- E-2000: A versatile small form factor connector, that may have an electrical termination, developed by Diamond.
- MTP®: Multi-fiber connector housing up to 24 fibers in a single ferrule, manufactured by US Connec Ltd.
- MPO: Multi-fiber connector housing up to 24 fibers in a single ferrule
- SMA: Connector that uses threaded interface, developed in 1960s and still used today.
- MPX®: Multi-fiber connector with 4-24 fiber terminated in single ferrule, manufactured by Molex
- HBMT: High Density Backplane MT connector that uses standard MT ferrule as the optical interface, and provides up to 96 fiber interconnects.
