Cisco GLC-SX-MMD – 1000BASE-SX Gigabit SFP Transceiver Module (MMF, 850nm, DOM)

The Cisco GLC-SX-MMD – 1000BASE-SX Gigabit SFP Transceiver Module (MMF, 850nm, DOM) is a reliable and high-performance optical module designed for short-range data transmission over multimode fiber (MMF). Supporting Gigabit Ethernet speeds (1Gbps), this module is ideal for enterprise networks, campus environments, and data centers that require stable and cost-effective connectivity.

Operating at an 850nm wavelength, the Cisco GLC-SX-MMD is optimized for short-distance communication, typically supporting up to 550 meters on OM2/OM3 multimode fiber. This makes it perfect for inter-switch links, server connections, and high-speed internal network setups.

The module features Digital Optical Monitoring (DOM), allowing administrators to monitor real-time performance metrics such as temperature, voltage, and optical power levels. This helps ensure network reliability and simplifies troubleshooting.

With its LC duplex connector, the transceiver ensures secure and efficient connections, while the hot-swappable design enables quick installation or replacement without disrupting network operations. Fully compatible with Cisco networking equipment, this module delivers seamless integration and dependable performance.

Whether you are upgrading your LAN infrastructure or expanding your network, the Cisco GLC-SX-MMD provides a cost-effective, high-speed, and efficient fiber solution for short-distance connectivity.
