Abstract
A first optical module includes an optical transceiver and a chip. The optical transceiver, subsequent to completion of link training of an in-band transmission link between the first optical module and a host device, waits for a second optical module to come up including transmitting a first awake signal from the first optical module to the second optical module, and receives a second awake signal from the second optical module when the second optical module is up. The chip i) based on a first out-of-band signal transmitted via an out-of-band link, performs the link training of the in-band transmission link independently of an in-band reception link between the first optical module and the host device, and ii) based on the second awake signal and a second out-of-band signal transmitted via the out-of-band link, performs link training of the in-band reception link independent of the in-band transmission link.
