In the realm of computer networks, connections between various devices are predominantly established using two types of network cables. Copper-based network patch cables are primarily utilized for shorter connections, extending up to 328 feet (100 meters). These cables facilitate connections between computers and network switches or routers, link wireless access points to the network, or establish an uplink from one network switch to another. However, for connections exceeding 100 meters, a different type of cable is required: the optical-fiber cable.

This guide discusses the fundamentals of fiber optic patch cables, also known as fiber optic jumper cables.
