SFP28 Electrical Loopbacks

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

The SFP 28 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 EL-18-08001 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.
