Cisco NIM-1GE-CU-SFP Network Interface Module is a 1-port Gigabit Ethernet SFP module designed for Cisco routers with NIM slots. It provides a single Gigabit Ethernet link via copper connectivity through the SFP interface, intended for use where copper-based 1 Gbps connectivity is required. Described as a dual-mode GE SFP module, it supports operation across compatible Cisco platforms that accept NIM modules, enabling flexible modular upgrades. This module adds a dedicated 1 Gbps Ethernet port to a supported router without replacing existing chassis hardware.
