A fiber patch cable is a fiber optic cable with connectors on both ends. They are also called fiber jumpers. A fiber-optic patch cord is constructed from a core with a high refractive. When you build or upgrade a fiber network, the same four words pop up everywhere— fiber optic (bare fiber), pigtail, patch cord, optical cable. Mixing them up drives costs higher, increases loss, and slows your rollout. These connectors allow quick connection between optical equipment such as switches, patch panels, optical transceivers, and distribution boxes.
