This FC-SC fiber optic patch cord is designed to create a reliable connection between networking equipment using different interface standards. It features an FC connector on one end and an SC connector on the other, making it useful for linking devices like patch panels to switches or routers. The cable spans 5 meters and is encased in a yellow jacket, which typically identifies it as a single-mode fiber. This specific fiber type allows for efficient data transmission over longer distances with minimal signal loss, while the durable outer coating protects the delicate glass core from everyday wear.
