25G SFP28

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.

In addition to the electrical loopback function, the SFP28 loopback provides a MSA standard 2-wire serial communication interface to digital diagnostics. This provides information about the present operating conditions and the pre-loaded EEPROM memory map. Both standard and custom memory maps are available.
