Network Transceiver Module Cisco GLC-LH-SMD

The Cisco GLC-LH-SMD is an industry-standard SFP (Small Form-Factor Pluggable) gigabit transceiver module that provides hot-swappable fiber connectivity for Gigabit Ethernet ports. Operating at 1000 Mbit/s with a 1300 nm wavelength and an LC fiber connector, this module is compatible with a wide range of Cisco platforms including Catalyst Express 500/520 and ME/Catalyst series such as ME 3400/3600X/3800X/4900/6500. It is designed for reliable data transfer and straightforward integration when expanding or upgrading fiber links.

Advantages

The GLC-LH-SMD offers standardized SFP form factor compatibility, hot-swappable installation without powering down equipment, and support for long-wavelength single-mode fiber transmission at 1300 nm. Its LC connector and 1000 Mbit/s throughput make it suitable for common gigabit fiber deployments, and its Cisco model compatibility simplifies replacement and inventory management across multiple device families.

Suitable for

• Upgrading or expanding Gigabit Ethernet fiber links on Cisco switches and routers
• Interchanging SFP modules across Catalyst and ME series devices
• Single-mode fiber connections requiring LC connectors and 1300 nm wavelength

Key specifications

• Interface type: SFP
• Maximum data transfer rate: 1000 Mbit/s
• Wavelength: 1300 nm
• Connector: LC (fiber optic)
• Manufacturer part number (MPN): GLC-LH-SMD
• EAN: 5054533411135

How to use

Insert the GLC-LH-SMD into an SFP slot on a compatible Cisco device until it clicks; the module is hot-swappable so no shutdown is required in most deployments. Connect single-mode fiber with LC connectors to the transceiver, verify link status and port configuration in the device management interface, and adjust network settings (speed/duplex or SFP-specific settings) as needed for your topology.

Recommendations

Use this module with compatible Cisco hardware listed in product documentation and ensure fiber type and connector match (single-mode LC). Verify firmware and software compatibility on the host device and handle the transceiver by the housing to avoid contamination of fiber interfaces.
