1000BASE-LX/LH Cisco SFP Module GLC-LH-SMD For 10km Singlemode Fiber

Cisco GLC-LH-SMD: Versatile Gigabit SFP for Fiber Networks

The Cisco GLC-LH-SMD is a reliable 1000BASE-LX/LH SFP transceiver module, designed for Gigabit Ethernet connections over both single-mode and multimode fiber. It provides essential high-speed connectivity for a variety of networking environments, ensuring flexible deployment options. While primarily used for linking Cisco Network Switch devices, its role is foundational for any modern wired or wireless setup.

Flexible Fiber Connectivity

This SFP supports diverse fiber types: up to 10 kilometers over single-mode fiber and up to 550 meters over multimode fiber. This versatility makes it ideal for mixed fiber environments.

Real-Time Performance Monitoring

Equipped with Digital Diagnostic Monitoring (DDM), the GLC-LH-SMD allows IT teams to monitor key parameters like optical input/output power, temperature, and voltage in real-time. This simplifies troubleshooting and network maintenance.

Standardized & Hot-Swappable

As an industry-standard SFP, it's hot-pluggable for easy installation or removal without disrupting network operations. It's compatible with a wide range of Cisco devices supporting SFP ports.

Enhancing Network Infrastructure

The GLC-LH-SMD is critical for extending gigabit links between buildings or across campus networks. It provides the necessary optical backbone for connecting Cisco Network Switch devices and supplying high-bandwidth uplinks to support Cisco Wireless AP deployments.
