SC connector

SC connector

(Standard Connector, Subscriber Connector) A fiber-optic cable connector that uses a push-pull latching mechanism similar to common audio and video cables. For bi-directional transmission, two fiber cables and two SC connectors (Dual SC) are used. SC is specified by the TIA as FOCIS-3. See fiber-optic connectors, LC connector and FOCIS.

SC and LC Connectors
SC and LC connectors use a push-pull plug similar to audio and video plugs and sockets. SC connectors have a 2.5mm ferrule, whereas the smaller LC is only 1.25mm.
