Cisco NIM-1GE-CU-SFP is a 1-port Gigabit Ethernet WAN network interface module for Cisco routers. It provides dual-mode connectivity with both a copper RJ-45 interface and an SFP port, enabling WAN links over copper or fiber. As a WAN NIM, it adds a single GE port to Cisco router configurations that support NIM modules, delivering flexible, modular WAN access within the chassis.
