SC/APC fiber optic cables are fiber patch cables featuring SC (Subscriber Connector or Standard Connector) connectors with APC (Angled Physical Contact) polishing. They are often used in environments with critical low back reflection, such as telecommunications and data center applications. They're especially useful for single mode fiber applications involving longer distances and higher data rates, as well as their ability to resist electromagnetic interference. The SC fiber optic connector, or the "Square Connector," was the first to be included in the TIA-568 standard. Its square-shaped body and snap-in, push-pull latch design make it easy to use. With a 2.5mm ferrule, it provides low insertion loss and stable performance. Even after multiple plug-ins and unplugging, the cable maintains consistent quality. This makes the SC connector ideal for telecom and datacom applications, such as point-to-point connections and passive optical networks. It is also widely used in polarization-maintaining systems.
