The SC/APC duplex patch cord is a fiber optic cable assembly featuring two SC connectors with Angled Physical Contact (APC) polish, designed for low-return-loss, high-performance singlemode optical transmission. It consists of two parallel fibers for bidirectional communication, typically housed in a yellow jacket with green SC/APC connectors. This patch cord is used to interconnect optical devices in applications requiring stable, high-bandwidth, and low-reflection connections, such as in FTTx networks, data centers, and telecom environments.
