Notes

Other brands of QSFP+ SR optical modules don't work with the Intel® Ethernet Converged Network Adapters.

When two Intel® Ethernet Converged Network Adapter XL710 Series QSFP+ devices are connected back to back, we recommend configuring them with the same Speed/Duplex setting. Results may vary with mixed speed settings.

Airflow and temperature guidelines for Intel® Ethernet QSFP+ LR4 Optic:
55°C @ 400LFM
50°C @ 250LFM
45°C @ 150LFM

Optical Module Requirements for Intel® Ethernet Converged Network Adapters with QSFP+ Open Optics Support
Intel® Ethernet Converged Network Adapters with QSFP+ Open Optics Support are designed to support either Power Class 1 modules or Power Class 4 modules as defined in the SFF-8679 specification. Refer to the Intel documentation for the recommended Intel Ethernet Converged Network adapter for the supported Power Class.

When Intel® Ethernet QSFP+ Optics modules are used, adapter use conditions for ambient temperature and airflow are verified to meet the Standard Temperature Class of Operation as defined in the SFF-8679 specification. For use of other optics modules, it's the system integrator’s responsibility to determine the necessary ambient temperature and airflow for the third-party optical modules to operate within the Temperature Class of Operation at all times.

Operating optical modules outside the supplier specified Temperature Class of Operation range will permanently reduce the performance of the optical module over time.
