10GBASE-LR SFP+ transceiver

The Black Box LSP422 is a 10GBASE-LR SFP+ transceiver built for single-mode fiber links up to 10 kilometres. It operates at a 1310-nm wavelength and supports line rates between 9.95 and 11.32 Gbps. The module fits standard SFP+ ports on enterprise switches and routers.

Thermals, noise and power

The transceiver is a passive optical module with no moving parts, so it adds negligible acoustic noise to the rack. Power draw is low and scales with the host port budget, keeping thermal contribution minimal in dense deployments. Normal operating temperatures follow the host system’s airflow design.

Duplex LC connector and reach

A duplex LC connector provides the physical interface for two single-mode fibers, enabling the full 10 km reach without intermediate amplification. The 1310-nm laser and matched receiver are calibrated for that distance, simplifying link planning for campus or metro spans. No additional software or licensing is required beyond the host platform’s standard SFP+ support.

Questions about this item

How do I install the LSP422 SFP+ transceiver and what step is often missed?

Insert the module into a compatible SFP+ port until it clicks, then connect single-mode LC fiber; the step often missed is removing the dust caps from both the transceiver and the patch cable before linking.

What maintenance or replacement will the LSP422 need over time?

The LC connectors and fiber end-faces should be inspected and cleaned with a lint-free wipe and isopropyl alcohol whenever links are reconfigured; no internal components are user-serviceable.

What limit appears first when the LSP422 runs at full load for long periods?

The 10-kilometer single-mode reach and the 9.95–11.32 Gbps operating window define the distance and signal-integrity ceiling; sustained use beyond that range degrades the optical link.
