Black Box Corporation E-LR SFP+ EXT DIAGSM 1310 LC 10KM LSP422 SFP transceiver

10 km 10GBASE-LR SFP+ transceiver

This transceiver delivers 10 Gigabit Ethernet connectivity over single-mode fibre at a 1310 nm wavelength. It is built for network operators and system integrators extending links up to ten kilometres. The module uses an LC duplex connector and complies with the 10GBASE-LR standard. It suits enterprise and campus deployments needing reliable long-reach performance.

Practical limits of the 10GBASE-LR interface

The 10GBASE-LR standard defines operation over single-mode fibre at 1310 nm with a nominal reach of ten kilometres. Actual link distance depends on the quality of the installed cable plant and connector loss budget. The module requires an LC duplex patch cord and compatible SFP+ ports on both ends. It does not support multi-mode fibre or shorter-reach LRM variants.

Extended diagnostics and temperature range

This unit carries the EXT DIAGSM designation, indicating extended diagnostic monitoring and an industrial temperature rating. That combination is the deciding factor for deployments in unconditioned cabinets or outdoor enclosures where standard-temperature modules would fall outside their operating envelope. Buyers who only need a standard-temperature LR module for a climate-controlled data centre do not require this specification.
