SC Connector (‘S’ubscriber ‘C’onnector)

The SC connector holds a single fiber in a standard-sized (2.5 mm) ceramic ferrule.  The connector body has a square front profile, and is made of moulded plastic.  Clips on either side of the body and the connector key allow for easy push-in connections.  This push-pull latching mechanism makes the SC connector preferred in high-density interconnect applications such as telecommunications closets and premise wiring.  Two SC connectors may be mounted side by side on duplex cable.  SC connectors have been preferred by the TIA/EIA-568-A industry standard for premise cabling because it is felt to be easier to maintain the polarity of duplex cables with this type of connector.

 * SC-PM assemblies are available, with the SC key aligned to either the fast or slow polarization axis
