ST and SC connectors
There are many types of plugs and sockets available to connect optical fibers; the most common connector used with fiber optic cable are:
ST (Straight Tip) connector: It is barrel shaped and is similar to a BNC connector.
SC (Subscriber Connector or Standard Connector): Easier to connect in a confined space and it is squared faced.
Attaching a connector to an optical fiber takes much effort than copper wire connectors because the ends of the fiber usually have to be carefully cemented and then polished in order to let the maximum light pass through.
The SC and ST connectors are field-installable, multimode fiber optic connectors. The ST connector is used only on NICs for fiber optic networks such as 10BaseFL or 100BaseFX.
