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

The Cisco NIM-1GE-CU-SFP Network Interface Module is a single-port Gigabit Ethernet NIM that uses a copper SFP transceiver to deliver 1 Gbps of Ethernet through a Cisco router. Designed for installation in a compatible router’s Network Interface Module slot, it adds one copper-based GE link via the SFP interface and is described as a dual-mode GE SFP. Its compact form factor fits standard NIM slots on supported Cisco platforms. This module supports typical copper Ethernet deployments, connecting to switches, servers, or other network devices over Cat5e/Cat6 cabling where a 1 Gbps copper connection is required. As a Cisco NIM, it integrates with the router’s management and configuration framework, enabling port-level control and monitoring alongside existing interfaces.
