Cisco NIM-1GE-CU-SFP Network Interface Module

The Cisco NIM-1GE-CU-SFP Network Interface Module adds a Gigabit Ethernet uplink to Cisco ISR 4000 Series routers, providing one copper RJ45 port and one Gigabit Ethernet SFP slot for flexible WAN or LAN connectivity. As a plug-in NIM expansion module, it supports 10/100/1000 Mbps data rates and enables router uplink connections to switches, fiber networks, or WAN circuits. With copper Ethernet and fiber SFP interfaces, it supports deployment in enterprise branch offices, data communication gateways, and service provider edge networks where additional high-speed Ethernet interfaces are required. Common applications include network expansion, infrastructure upgrades, and replacement of existing interface modules within ISR platforms. Compatibility notes: Cisco ISR 4000 Series routers (including ISR 4300 and ISR 4400 Series). Common replacements: Cisco NIM-2GE-CU-SFP; Cisco EHWIC-1GE-SFP-CU; Cisco NIM-ES2-4.
