This Cisco SFP module is designed for network administrators and IT professionals managing Gigabit Ethernet networks who need a reliable, hot-swappable interface converter. Its key benefit is providing long-reach connectivity up to 10km over single-mode fiber, with the caveat that multi-mode fiber connections may require mode conditioning cables for optimal performance. This module efficiently links switches and routers to the network, offering flexibility in port configuration and ensuring high uptime.

This module supports a maximum transfer distance of 10 kilometers over standard single-mode fiber optic cables.
Yes, it can operate over multi-mode fiber for distances up to 550 meters. However, it is recommended to use a mode conditioning patch cable for optimal performance in this configuration.
The module uses a standard LC/PC fiber optic connector.
Yes, the Cisco GLC-LH-SMD= SFP module is hot-swappable, meaning it can be installed or removed without needing to power down the network device.
It complies with IEEE 802.3, IEEE 802.3ab, and IEEE 802.3u networking standards.
The module operates within a temperature range of -5 °C to 85 °C.
The maximum data transfer rate supported is 1000 Mbit/s (Gigabit Ethernet).
Ensure the module is fully seated in the SFP slot. Try reseating the module. Verify compatibility with your specific Cisco switch model. If the issue persists, try the module in a different SFP slot or on another compatible device.
Check the fiber optic cable connections at both ends for secure attachment. Inspect the fiber cable for damage. Ensure the correct type of fiber (single-mode or multi-mode) is used with the appropriate module settings and cable type. Clean the LC connector with a fiber optic cleaning tool.
Verify that the connected device and switch port are both configured for 1000 Mbit/s. Ensure the fiber cable is not exceeding its specified length limitations for the type of fiber and module. If using multi-mode fiber, confirm that a mode conditioning patch cable is in use.
Setup: This SFP module is designed for plug-and-play installation into compatible SFP ports on Cisco switches and routers. Ensure the network device is powered on, then carefully insert the module into the SFP slot until it clicks into place. No configuration is typically required for basic operation; the module is recognized automatically by the host device.
Compatibility: The GLC-LH-SMD= module is compatible with a wide range of Cisco devices, including Catalyst Express 500/520, Catalyst 2940/2950/2960/2960-S/2960-C/2970/2975, Catalyst 3560/3560-E/3560-X/3560-C, and Cisco ME 3400/3600X/3800X/4900/6500 series switches. Always refer to your specific device's documentation for a definitive compatibility list.
Care: The module operates within a temperature range of -5 °C to 85 °C. Avoid exposing it to extreme temperatures, moisture, or dust. When handling, use an anti-static wrist strap. To clean the fiber optic connector, use only approved fiber optic cleaning tools and solutions. Ensure protective caps are on the connector when not in use to prevent contamination.
