Lucent Technologies first developed the LC connector for TelCo environment uses; LC stands for Lucent Connectors. The LC connector is a small form factor fiber optic connector. The LC connector resembles a small SC connector. The LC connector has been standardized as FOCIS 10 (Fiber Optic Connector Intermateability Standards) in EIA/TIA-604-10. The LC connector uses a 1.25 mm ferrule, half the dimension of the ST ferrule or a regular ceramic ferrule connector.
Features of LC Connectors: half the dimension of regular connectors, push & pull mechanism, detachable clips for simplex as well as duplex connectors.
