Description:

The Cisco GLC-SX-MMD SFP Transceiver Module is used in Gigabit Ethernet networking systems to provide high-speed optical connectivity over multimode fiber in switches, routers, and network infrastructure devices. Commonly installed in enterprise data centers, campus networks, network access switches, and server connectivity environments where reliable short-range fiber communication is required. Network engineers, IT administrators, and system integrators use this module for fiber network expansion, switch uplink connectivity, and replacement of failed SFP modules in Cisco networking equipment.

Applications:

The Cisco GLC-SX-MMD SFP module enables Gigabit Ethernet communication over multimode fiber links in enterprise and data center network environments. It is widely used to interconnect network switches, routers, and servers within campus networks, office buildings, and equipment rooms where short-distance fiber connectivity is required. The module supports high-bandwidth data transmission and allows network infrastructure to maintain reliable communication between distribution and access layer devices.
