Description:

The Cisco SM-2GE-SFP-CU Service Module is used in Cisco Integrated Services Routers to provide additional Gigabit Ethernet connectivity through SFP interfaces for enterprise networking and WAN aggregation. This service module includes two EHWIC-1GE-SFP-CU interface cards, allowing routers to support high-speed copper Gigabit Ethernet connections using SFP modules. Designed for Cisco ISR platforms, the module expands router networking capabilities by enabling flexible uplink connectivity to switches, service provider networks, or additional network infrastructure. Its modular design allows organizations to increase network bandwidth and connectivity options without deploying separate external switching hardware. The module integrates directly into the router chassis and operates under Cisco IOS for centralized configuration and monitoring. Network administrators and system integrators commonly install this module for network expansion, WAN connectivity upgrades, infrastructure modernization, and replacement of existing interface modules in Cisco router deployments.

Applications:

The Cisco SM-2GE-SFP-CU service module is commonly deployed in enterprise branch routers that require additional Gigabit Ethernet uplink connectivity. It is frequently used in Cisco Integrated Services Router environments to connect routers to aggregation switches, service provider links, and core network infrastructure. Organizations install this module in corporate networks, branch offices, telecommunications sites, and distributed enterprise environments where flexible Ethernet connectivity and scalable network expansion are required.
