10km Single-Mode SFP Transceiver

The Brute Networks GLC-FE-100LX is a 100BASE-LX SFP transceiver built for single-mode fibre links up to 10 kilometres. It operates at a 1310nm wavelength with an LC duplex connector and delivers a 100 Mbps transfer rate. Network engineers use it to add or replace a long-reach uplink on Cisco routers, switches or servers.

Replaces Costly OEM Long-Reach Modules

This third-party module is coded for 100 percent Cisco compatibility and meets MSA standards, so it initialises identically to the original part. The jump is worth it when a deployment needs 10km reach at 100 Mbps without paying OEM list prices. It is not suited for links that require higher bandwidth or multi-mode fibre.

Commercial-Temperature Sustained Operation

Rated for 0 to 70 degrees Celsius, the transceiver maintains link stability under continuous load across the full commercial temperature range. Digital optical monitoring provides real-time health data during extended runs. The 1 oz weight and standard SFP form factor ensure consistent airflow in dense chassis.

Questions about this item

Which fiber connector and cable type does this 1310nm SFP need for a 10km link?

It uses an LC duplex connector with single-mode fiber to reach 10km at 1310nm.

What is the correct way to seat this SFP in a Cisco switch slot, and what step is often missed?

Slide the module in until the latch clicks, then remove the dust caps and insert the LC cables; skipping the latch click leaves the link down.

When should the transceiver be replaced given its operating temperature range?

Plan replacement if the ambient temperature exceeds 70 °C or if link errors appear after extended operation at the upper limit.
