The SC Duplex Connector is a standardized, field-installable fiber optic interface designed for reliable dual-channel optical signal transmission in both single-mode (SM) and multimode (MM) applications. This connector family features two SC simplex connectors integrated within a unified duplex clip or housing, ensuring precise polarity alignment (Position A/B or flip-style) for transmit and receive channels. It is engineered to deliver low insertion loss and high return loss, meeting or exceeding industry standards such as IEC 61754-4 and TIA-568.
