Our loopback test adapters enable cost-efficient methods for SFP+ port testing of high performance switches and server blades. Loopbacks route data from the host back to the port, closing the communication loop for testing purposes. During testing, a potential data loss, as well as temperature and voltage levelling can be monitored and recorded to its customized loopback memory map. SFP+ loopback test adapter support 10Gbps total data rate, as well as different power classes. It is available with an optional bicolor LED light indicating the operating power mode. Our SFP+ loopbacks are fully SFF compliant and provide a 2-wire serial communication interface for memory map loading and diagnostic functions. This test adapters is hot pluggable and thermally designed to operate between 0° to 70 °C (32 ° to 158 °F). Optional loopback clamp 4-port loopback clamps enable simultaneous testing of four ports at once. They possess all features of a single SFP56 loopback test adapter with an extra lock-protection to ensure safe locking during the measuring process.
