Abstract
A first host device, governing operation of an optical module, includes a transmitter, an out-of-band electrical interface, and an engine. The transmitter transmits in-band signals on an in-band electrical interface from the first host device to the optical module. The first host device communicates with a second host device over an optical medium via the optical module. The communication includes transmission by the optical module of optical signals to the second host device. The optical signals are generated based on the in-band signals. The out-of-band electrical interface transmits first out-of-band messages from the first host device to the optical module and receives second out-of-band messages from the optical module. The engine transmits one of the in-band signals on the in-band electrical interface to the optical module, receives feedback via the out-of-band electrical interface, the feedback being based on the one of the in-band signals, and based thereon tunes the transmitter.
