A fiber patch cable is a fiber optic cable with connectors on both ends. They are also called fiber jumpers. These connectors allow quick connection between optical equipment such as switches, patch panels, optical transceivers, and distribution boxes. Think of it as a bridge that lets data flow between equipment, like linking a router to a switch, a server to a storage device, or even. A fiber optic patch cable (also called a fiber jumper or fiber patch cord) is a section of optical fiber cable with connector terminations on both ends, designed for flexible, short-distance interconnections within an optical network.
