A fiber patch cable is a fiber optic cable with connectors on both ends. They are also called fiber jumpers. As data rates increase from 10G → 100G → 400G → 800G, patch cables must handle more bandwidth, more density, and stricter. Fiber optic patch cords, also known as fiber optic patch cables or fiber jumpers, are indispensable components in modern optical networks. As they do not emit electromagnetic signals, they're difficult to tap and secure against eavesdropping. One way to inter connect AB and BC segments is by fusing a pair of required fiber cores.
