LC Connector
LC stands for Lucent Connector. It is a small form-factor fiber optic connector that uses a 1.25
mm ferrule, which is half the size of the ST / SC connectors.
It uses a standard ceramic ferrule connector. The LC has good performance and is highly
favored for both multimode and single mode applications, especially in high-density connector
facilities. The LC connector is available in simplex or duplex cables.
SC Connector
SC officially stands for Subscriber Connector; however, some people believe that "Square
Connector", is the correct name. It is a general purpose push/pull style connector. It was
developed by NTT, which has an advantage in LAN/enterprise networks where duplex cabling
to support TX/RX channels are commonly used.
SC Connectors are frequently used network applications. The connector is square and keyed
with push-pull mating, 2.5mm ferrule, and molded housing for protection. The SC is a snap-in
connector that is widely used in singlemode systems due in part for its performance. The snap-
in connector latches with a simple push-pull motion.
