Loopback test adapters for data centers

Loopback test adapters for data centers

LEONI loopback test adapters for SFP interfaces support 10 GB and 25 GB total data rate. They are fully SFF compliant and provide a 2-wire serial communication interface for memory map loading. LEONI test adapters are hot pluggable and thermally designed to operate between 0° to 70 °C (32° to 158 °F). Meanwhile, LEONI QSFP loopback test adapters support 40 GB and 100 GB total data rate, as well as different power classes. They are available with an optional bicolour LED indicating the operating power mode and also shows if the module is selected by the switch. LEONI QSFP loopbacks are fully SFF compliant and provide a 2-wire serial communication interface for optimum temperature, voltage monitoring as well as memory map loading. LEONI test adapters are hot pluggable and thermally designed to operate between 0° to 70 °C (32° to 158 °F).
