Cisco GLC-LH-SMD Gigabit SFP Transceiver Module (MMF/SMF)

Cisco GLC-LH-SMD is a 1000BASE-LX/LH SFP module designed for high-speed data transmission across both Multimode Fiber (MMF) and Single-Mode Fiber (SMF). This module provides flexible, high-performance networking connectivity, offering 10 km reach on single-mode fiber and up to 550 meters on multimode fiber, making it ideal for both short and long-distance connections in various networking environments.

The 1300-nm wavelength ensures reliable and high-quality data transmission, with compatibility to the IEEE 802.3z 1000BASE-LX standard for Gigabit Ethernet applications. The module supports Digital Optical Monitoring (DOM) for real-time monitoring of key parameters such as temperature and optical power, providing network administrators with critical diagnostics and improving network management.

This dual LC/PC connector SFP module is engineered for use in enterprise and service provider networks, allowing you to easily scale your network infrastructure for higher data transmission needs. The module is also hot-pluggable, allowing for seamless installation without powering down your equipment.
