SFP+ Loopback

SFP+ Loopback 

SFP+ electrical loopback is used for testing SFP+ transceiver ports in host/system boards. By substituting a full-featured SFP+ transceiver, the electrical loopback provides a cost effective method for SFP+ port testing. Attenuation options are available in nominal and attenuated versions including 0db, 3.5db and 5db; power options are 1W, 2W, 2.5W; plug in and out can reach to 500times.

SFP+ loopback is packaged in an MSA compliant housing offering excellent heat dissipation, compatible with all SFP+ ports. Transmit data from the host is electrically routed, (internal to the loopback module), to the receive data outputs and back to the host. Since the loopback module does not contain laser diodes, photodiodes, a laser driver or transimpedance amplifier chips, etc., it provides an economical way to exercise SFP+ ports during R&D validation, production testing and field analysis.

 

SFP28 Loopback

SFP28 electrical loopbacks provide a method for port operations testing in board, hub, system, and other applications.

Attenuation options are available in nominal and attenuated versions including 0db, 3.5db and 5db; power options are 1W, 2W, 2.5W; plug in and out can reach to 500times.

The SFP28 electrical loopback supports Fibre Channel, Gigabit Ethernet, and Infiniband protocols, and is capable of achieving up to 100 Gbps data transfer rate.

This provides information about the present operating conditions and the pre-loaded EEPROM memory map. Both standard and custom memory maps are available
