There are many different types of connectors which have evolved as standard in various applications. The most common of these are described below. With these connector body types there is a ferrule within the plug housing, with the fiber glued in along the central axis, and this can be polished flat or angled.
FC - have a key notch in the hole with corresponding key on the body, with a threaded ring to tighten the plug into the socket.
SC - have plastic box-type housing around the ferule and clip into place with a plastic notch mating into the socket.
LC - similar to SC, but the plastic notch holding the plug into the socket has a small plastic sprung lever.
ST – an old type connector still occasionally seen, with a BNC type notched fitting, push-rotate-lock action.
PC - Flat polish connector, sometimes specified in variants Super PC, Ultra PC or PC
APC - Angle polish connector
An angle polish will reduce back reflections by ensuring that back scattered light exceeds the acceptance angle of a fiber – these connectors are conventionally fabricated with green housing and stress relief to distinguish them from standard flat polish connectors.
