Connectivity and compatibility

This transceiver module fits into any standard SFP+ slot, making it compatible with Intel Ethernet Converged Network Adapter X520 series and other switches or servers that support SFP+ modules. It uses LC connectors for single-mode fiber connections, which are common in long-distance network setups. This flexibility allows network architects to extend links without replacing existing fiber infrastructure or installing new copper cabling.

Ideal uses and environments

The E10GSFPLR is well suited for connecting top-of-rack switches to distant aggregation layers, linking separate buildings within a campus, or extending storage traffic to remote backup sites. Its broad temperature tolerance makes it reliable in server rooms, telecommunications closets, and lightly conditioned remote cabinets. This module is a strong choice for IT professionals who need a stable, long-distance fiber connection that supports both current Gigabit and future 10 Gigabit Ethernet speeds.
