Cisco C3KX-SM-10G 10GB SFP+ Service Module 3750X 3506X Switch C3KXSM10G

Description:

The Cisco C3KX-SM-10G Service Module is a 10 Gigabit SFP+ network expansion module designed for Cisco Catalyst 3560-X and 3750-X Series switches to provide high-speed uplink connectivity within enterprise network infrastructures. It enables switches to support 10 Gigabit Ethernet connections using SFP+ transceivers, allowing improved bandwidth and faster data transfer between access, distribution, and core network layers. The module integrates directly into compatible Cisco switches to expand network capacity and support high-performance enterprise LAN and data center connectivity. Commonly installed in Cisco Catalyst 3560-X and 3750-X switches used in corporate campus networks, data centers, and enterprise distribution layers where high-speed fiber uplink connectivity is required. Maintenance teams, network administrators, and system integrators deploy this module for network backbone upgrades, uplink bandwidth expansion, infrastructure improvements, or replacement of existing switch uplink modules.

Applications:

The Cisco C3KX-SM-10G module is used in enterprise networking environments to provide high-speed 10 Gigabit uplink connectivity for Cisco Catalyst switches. It is commonly deployed in corporate campuses, data centers, and enterprise distribution networks where network administrators require faster backbone connections between switches, servers, and core infrastructure. Network engineers install this module to increase uplink bandwidth, support fiber-based high-speed communication, and improve data transfer performance across large organizational networks.
