SC/APC SM Connector
SC is a snap-in connector with a 2.5 mm ferrule that is widely used for it's excellent performance keying of the angle cleaves is important for optical reflection performance.
SC Connectors provide non-optical disconnect terminations in a push-pull coupling mechanism. It is also available in a duplex configuration.
The final solution for singlemode systems extremely sensitive to reflections, like CATV or high bitrate telco links, was to angle the end of the ferrule 8 degrees to create what we call an “APC” or “angled PC” connector. Then any reflected light is at an angle that is absorbed in the cladding of the fiber.
SC connectors are the most popular and used in LAN applications in any kind of active devices like hubs and switches.
The SC/APC compatible connector consists of a factory-polished fiber/ferrule assembly and a mechanical splice that is installed with a simple and reliable field tool. It is available with a standard, flat splice configuration or with a keyed, angle splice for excellent back reflection
