Description:

The Cisco SM-X-6X1G Service Module is used in Cisco Integrated Services Router platforms to provide additional Gigabit Ethernet connectivity through six SFP ports for enterprise network expansion. It supports dual-mode operation for Gigabit Ethernet interfaces designed to extend routing and switching capabilities within branch office and enterprise network infrastructures. Commonly installed in Cisco ISR 4400 Series routers deployed in enterprise branch offices, corporate network environments, and distributed IT infrastructures where additional fiber connectivity is required. Network administrators and system integrators use this module for network expansion, fiber uplink integration, infrastructure upgrades, and replacement of existing service modules in Cisco ISR platforms.

Applications:

The Cisco SM-X-6X1G module is used in enterprise branch networking environments where additional Gigabit Ethernet fiber connectivity is required within Cisco ISR 4400 Series routers. It is commonly deployed in corporate offices, financial institutions, retail network infrastructures, and distributed enterprise locations where fiber network connections link routers to switches, data centers, or service provider networks. The module supports high-speed data transmission between network devices while enabling scalable network expansion for growing enterprise infrastructures.
