Cisco GLC-SX-MM Compatible SFP Module - 1000BASE-SX 550m Multimode 850nm LC Transceiver
Couldn't load pickup availability
This high-performance 1000BASE-SX SFP transceiver is engineered for cost-effective short to medium-range connectivity over multimode fiber, delivering reliable Gigabit Ethernet up to 550 meters. Operating at 850nm, this module is ideal for campus networks, building-to-building connections, and data center environments where multimode fiber infrastructure is already deployed.
The module features full DDM (Digital Diagnostics Monitoring) support, enabling real-time monitoring of transceiver status, including optical power levels, temperature, and voltage, through most SNMP network management tools. This allows for proactive network maintenance and simplified troubleshooting across your infrastructure.
Fully compatible with Cisco switches and MSA (uncoded) standards, this transceiver serves as a direct replacement for Cisco's GLC-SX-MM module, offering exceptional value without compromising performance or reliability. The module works seamlessly with OM1, OM2, OM3, and OM4 multimode fiber types, with reach varying based on fiber quality.
