LC connector dimensions are engineered for minimalism, measuring just 4. 25mm in height for the duplex housing, which is half the size of SC connectors. The fibers shall terminate in 0. 25mm) ceramic ferrules with non-optical disconnect functionality and an average insertion loss of 0. LC F LC Fiber Optic Connectors provide a rugged solution for high-density telecommunication rooms. But exactly how big is an LC connector? Getting clear on its dimensions provides insights into how this component boosts speed and capacity. Simplex connectors include one LC connector, one boot, a crimp ring (not included for 900-micron), a dust cap, and duplex LC connectors include two simplex connectors plus a duplexing clip. 1dB. LC Adapters and Cable Assemblies meet the growing demand for small form factor, high-density fiber optic connectivity with simplex, duplex, single-mode and multimode options.
