The Belkin A7L504-1000-YLW is a 1000-foot bulk roll of Category 5e (Cat 5e) unshielded twisted pair (UTP) Ethernet cable. As bare wire, it allows for on-site termination with RJ-45 connectors or punch-down blocks, providing flexibility in network infrastructure deployment. This bulk cable is suitable for creating horizontal runs or backbone connections, enabling the establishment of new network segments or the expansion of existing ones with a consistent and manageable cable supply.
