1000BASE-LX SFP Transceiver

The Brute Networks GLC-LH-SM is a hot-pluggable SFP module that delivers 1 Gbps Ethernet over single-mode fibre. It operates at 1310nm wavelength and supports link distances up to 10km using LC duplex connectors. The unit is coded for full Cisco compatibility and complies with MSA standards for multi-vendor interoperability.

Network Teams Extending Campus Links

This transceiver suits administrators who need to bridge buildings or campus segments with existing single-mode infrastructure and Cisco switching gear. Digital optical monitoring provides real-time diagnostics for link health. It is not intended for multi-mode fibre runs, shorter-reach applications, or environments requiring industrial temperature ratings beyond the commercial range.

Stable Output Across 0-70 °C

The module maintains consistent laser power and receiver sensitivity throughout the rated commercial temperature span of 0 to 70 °C. MSA-compliant electrical and optical interfaces prevent link flapping during extended operation. Digital monitoring allows proactive detection of signal degradation before errors affect throughput.

Questions about this item

Does my switch need an SFP slot and single-mode fiber patch cables with LC duplex connectors to use this transceiver?

Yes, the module fits a standard SFP port and ships with an LC duplex connector for 1310 nm single-mode fiber links up to 10 km.

Can I mix this 1 Gbps 1310 nm module with older 1000BASE-LX optics on the same link?

Yes, it meets MSA standards and is coded for Cisco compatibility, so it initialises and runs identically to OEM transceivers in mixed deployments.

Which LEDs confirm the transceiver is operating correctly after installation?

The unit provides Power, Link/Activity, Full-Duplex and Speed indicators; steady Power and Link lights with Full-Duplex active show normal 1 Gbps operation.
