10GBase-LR modules use optical transceivers to send 10 Gbps data over single-mode fiber, which carries a focused, single-wavelength signal for long-distance switch-to-switch links. Many models use 1310 nm signaling and support links reaching up to 20 kilometers, depending on the module and fiber installation.

Check that the 10GBase-LR module uses a 1310 nm wavelength and an LC fiber connector, then verify that the switch supports the module’s SFP+ interface. Use single-mode fiber cabling, and confirm the module’s supported transmission distance, which may range from up to two kilometers to 20 kilometers.

Compare the module’s supported link distance, which in this assortment ranges from two to twenty kilometers, with the project’s fiber path and single-mode fiber requirements. Confirm that the module supports 10 Gbps throughput, 10GBase-LR operation, the required 1310 nm wavelength, compatible LC connectors, and the switch’s SFP+ port.

Many 10GBase-LR modules use a hot-swappable or hot-pluggable SFP+ form factor, allowing installation or replacement while compatible network equipment remains powered. Before starting, confirm that the switch supports 10G SFP+ modules and that the module matches the fiber type, wavelength, connector, and link distance required for the installation.
