This high-performance 1000BASE-LX/LH SFP transceiver is engineered for versatile medium to long-range connectivity, delivering reliable Gigabit Ethernet up to 10 kilometers over single-mode fiber or 550 meters over multimode fiber. Operating at 1310nm, this dual-capability module provides exceptional flexibility for network deployments with mixed fiber infrastructure.

The "LH" (Long Haul) designation indicates enhanced performance over standard LX modules, offering extended reach while maintaining compatibility with both fiber types. This makes it an ideal choice for metropolitan-area networks, campus backbone connections, and building-to-building links where fiber types may vary across different network segments.

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-LH-SM module, offering exceptional value without compromising performance or reliability.
