The switch stacking connection is a fiber optic cable
To connect multiple Ethernet switches, the best way is to use a multi-strand fiber cable. The 4-strand pre-terminated fiber optic cable consists of four individual strands or fibers of glass or plastic fibers enclosed in a protective sheath. The corresponding port is generally on the back of the switch, is unique, and will not cause connection errors. Stackable switches improve network scalability, reliability, and flexibility by increasing bandwidth and simplifying device management. If traffic needs to be forwarded through stack cables. Switch stacking is a feature of certain Cisco access layer switches which allows for the creation of a single logical device from many individual devices via a backside stack port connected by several stack cables.
