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

The Cisco GLC-LH-SMD – Gigabit SFP Transceiver Module (MMF/SMF) is a versatile and high-performance optical module designed for Gigabit Ethernet connectivity over both single-mode fiber (SMF) and multimode fiber (MMF). Supporting the 1000BASE-LX/LH standard, this module is ideal for enterprise networks, campus infrastructure, and data centers that require flexible and reliable fiber connections.

Operating at a 1310nm wavelength, the Cisco GLC-LH-SMD provides stable long-distance communication, supporting up to 10 kilometers over single-mode fiber (SMF). It can also operate over multimode fiber (MMF) for shorter distances when used with a mode-conditioning patch cable, making it a highly adaptable solution for mixed network environments.

This module features Digital Optical Monitoring (DOM), allowing network administrators to monitor real-time performance parameters such as temperature, voltage, and optical power levels. This enhances network reliability and simplifies maintenance.

The LC duplex connector ensures secure and efficient fiber connections, while the hot-swappable design allows easy installation and replacement without disrupting network operations. Fully compatible with Cisco networking equipment, the GLC-LH-SMD integrates seamlessly into existing systems.

Whether you are extending your network over long distances or connecting mixed fiber types, this Cisco SFP module delivers reliable performance, flexibility, and cost-effective Gigabit connectivity.
