The SC connector is the most widely used connector today. It is found on a large number of active devices regardless of the application (Ethernet, Fiberchannel, etc.). It has many advantages over ST connectors: less protrusion of the tip, therefore no risk of pollution, “pull-proof” design, therefore no risk of disconnection when pulling on the cable, rectangular section for better handling and improved guidance inside the connector. It complies with the IEC 60874-14 standard and is called SC (“Subscriber connector”).
The LC dual-fiber connector features 1.25 mm ceramic ferrules and a plastic body. The fibers are spaced 6.25 mm apart. Developed by AVAYA, it reduces the size of existing connectors by half while maintaining proven technologies. It meets the IEC 61754-20 standard and is designated LC.
MPO stands for "Multiple-fiber Push On/Push Off." It is a solution for increasing the density of fiber optic cabling by relying on a standardized multi-fiber connector. Each connector integrates 12 optical fibers and is assembled on a fiber optic cable to form an MPO patch cord that can advantageously replace conventional pre-terminated links or pigtails.
MPO is a plug-and-play solution that allows for rapid deployment and does not require assembly tools.
The ST connector is reminiscent of BNC plugs; locking is achieved by a quarter turn of the outer ring. Offered by all, the ST connector has become a standard. It complies with the IEC 60874-10 standard and is designated BFOC 2.5.
Type of fiber polishing
PC: Type of finish of a plug. It corresponds to a polishing allowing to have a reflectance better than – 30 dB.
UPC: Type of finish of a plug. It corresponds to a polishing allowing for a reflectance better than – 50 dB.
APC: type of finish of a plug. It corresponds to a polishing allowing to have a reflectance better than – 60 dB.
PC and UPC finishes are compatible with each other. The APC finish is not compatible with PC and UPC finishes.
