Fiber optic patch cord, also known as fiber jumper, is a cable used to connect fiber optic devices. It typically consists of optical fibers and fiber optic connectors. It serves the purpose of transmitting optical signals in fiber optic networks and is used to connect devices such as fiber optic transceivers, optical modules, switches, routers, and more. Fiber optic patch cords offer low loss, high bandwidth, and resistance to interference, enabling high-speed and reliable data transmission. They play a crucial role in network cabling, device connectivity, and fiber optic maintenance.
