Product identity

The StarTech SFP10GBLRST is a 10GBASE-LR SFP+ transceiver built for single-mode fibre links up to 10 km. It suits network engineers extending 10 Gbps connections between switches or routers across campus or metro distances. The module plugs into any MSA-compliant SFP+ cage and uses an LC duplex connector. It is not for multimode fibre runs or distances beyond 10 km.

Thermals noise power

The transceiver draws less than 1.3 W during operation and runs without a fan, so it adds no audible noise to the rack. Operating temperature spans 0 to 70 °C with humidity tolerance of 5 to 95 % RH, allowing deployment in standard data-centre aisles. Storage temperature reaches -40 to 85 °C for spare inventory kept in unconditioned spaces. Power consumption stays constant regardless of link length.

Bundled value

The package contains only the transceiver itself; no patch cables, cleaning tools or diagnostic software are included. MSA compliance means the module works in third-party switches without vendor lock-in, reducing procurement friction. Hot-swap support lets technicians replace a unit without powering down the chassis, cutting planned-maintenance windows. No licence keys or firmware bundles accompany the hardware.

Questions about this item

How is the SFP+ transceiver installed, and which step do people often get wrong?

Slide the module into an SFP+ cage until it clicks, then insert the LC duplex connectors with the correct Tx/Rx orientation; reversing the fibers is the common mistake.

What maintenance or replacement will the SFP10GBLRST need later?

No scheduled maintenance is required; keep the LC ports covered when unused and replace the module only if link errors appear or optical output degrades.

What limit appears first under sustained use of this 10GBASE-LR transceiver?

The operating temperature ceiling of 70 °C is the first sustained-use limit; ensure adequate chassis airflow to stay below this threshold.
