Description:

The Cisco NM-1GE Gigabit Ethernet Network Module is used in Cisco Integrated Services Routers to provide additional Gigabit Ethernet connectivity for high-speed network communication. Commonly installed in Cisco 2811, 2821, 2851, 3825, and 3845 router deployments used in enterprise branch networks, WAN edge infrastructures, and business communication environments requiring expanded Ethernet interface capacity. Maintenance teams, network administrators, and system integrators use this module for router interface expansion, hardware replacement, and upgrading existing Cisco ISR platforms to support higher-speed network connections.

Applications:

The Cisco NM-1GE module is deployed in enterprise networking environments where additional Gigabit Ethernet interfaces are required for routing and network connectivity. It is commonly used in branch office networks, enterprise WAN infrastructures, and corporate communication systems where routers must connect to high-speed LAN switches, network backbones, or service provider links. Network engineers install this module in compatible Cisco Integrated Services Routers to expand network interface capacity and support improved data throughput.
