Intel MdlE10GSFPLR e10gsfplr SFP+ 10GBase LR Optic Module

The Intel E10GSFPLR SFP+ LR Optic Module is engineered to deliver high-speed 10 Gigabit Ethernet connectivity over single-mode fiber optic links spanning up to 10 kilometers. Designed specifically for use with Intel's X520 family of Ethernet Converged Network Adapters, this module provides the validated, first-party compatibility that enterprise and data center environments demand. With selectable bit rates from 1.25 Gb/s to 10.3 Gb/s, the module offers flexibility for various network topologies and speed requirements, whether you're provisioning a 1GbE link during migration or running at full 10GbE capacity.

The LR (Long Range) designation indicates this module uses a 1310nm laser wavelength optimized for single-mode fiber, which provides the distance reach needed for campus backbone connections, inter-building links, and data center-to-data center runs. As an Intel-branded optic, the E10GSFPLR avoids the compatibility warnings and potential firmware lockouts that can occur with third-party transceivers on Intel adapters, making it a straightforward choice for environments that standardize on Intel networking hardware and require guaranteed interoperability.
