Model Number:
LKF-SC
SC is one of the most common connectors in single-mode network equipment, frequently found on optical terminal units. It utilizes a 2.5 mm ceramic ferrule and, unlike ST or FC connectors, is a push-fit device requiring no rotation—a snap-in square interface. The “SC” in SC fiber optic connectors stands for Square Connector. Its rectangular form factor makes it an affordable option with easy insertion/removal, minimal insertion loss variation, high compression strength, and high installation density, contributing to its widespread adoption.
