SC connector. The SC connector was developed by NTT (Nippon Telegraph and
Telephone) of Japan. The connector is mated by a simple snap-in method and
can be disconnected by pushing in on a tab and then pulling the connector off.
SC connectors are available in either simplex or duplex configurations, as
shown in Fig. 8.13. Analogous to the ST connector, the SC connector uses a
ceramic ferrule and has similar loss characteristics. The mating and loss fea-
tures allow the connector to be used in tight spaces where turning an outer con-
nector housing, such as on an ST connector, is not practical. An example of such
spaces is a patch panel where there is a high packing density of connections.
SC simplex connectors have an outer plastic housing that is color-coded in
accordance with ANSI/TIA/EIA-568-B.3 and ISO/IEC 11801-1.2 requirements.
