Product Specifications

Description

1000BASE-LX/LH SFP Module (Cisco GLC-LH-SMD)

The Cisco GLC-LH-SMD 1000BASE-LX/LH SFP Transceiver is a hot-swappable Gigabit Ethernet optical module designed for high-performance fiber networking applications. It supports both Single-Mode Fiber (SMF) and Multi-Mode Fiber (MMF), delivering reliable 1 Gbps connectivity for enterprise networks, data centers, campus environments, and telecom infrastructures.

Operating at a 1310nm wavelength, the GLC-LH-SMD provides transmission distances of up to 10 km over single-mode fiber and up to 550 meters over multimode fiber. Its compact Small Form-Factor Pluggable (SFP) design allows easy installation and replacement without interrupting network operations. The module also supports Digital Optical Monitoring (DOM/DDM) for real-time performance monitoring and diagnostics.
