Abstract
A host device includes a transmitter, an out-of-band electrical interface and a processor. The transmitter transmits in-band signals on an in-band electrical interface from the host device to an optical module. The in-band signals are data signals transmitted to test a link between the host device and the optical module. The out-of-band electrical interface transmits first out-of-band messages from the host device to the optical module, and receives second out-of-band messages from the optical module. The first and second out-of-band messages being control messages for testing the link. The processor performs tests to test the link and selects a set of transmitter settings based on the tests. The processor: i) subsequent to performing the tests, receives via the out-of-band electrical interface one of the second out-of-band messages including an indication of the selected set; and ii) in response to receiving the indication, sets the transmitter according to the selected set.
