Abstract:
1. An optical module comprising: a laser driver corresponding with a channel of the optical module; a signal detector corresponding with the channel; link handshake state machine configured to control the laser driver to generate a connect pulse of a link handshake process to test an optical link between the channel and a corresponding channel of another optical module and monitor the signal detector to detect a connect pulse from the another optical module; an oscillator to generate a clock frequency; a connect-pulse generator coupled with the oscillator to provide a source signal to the laser driver for the connect pulse based on the clock frequency; and a power-on reset block coupled with the link handshake state machine to generate a reset signal when the optical module is powered up, wherein circuitry of the oscillator and circuitry of the connect-pulse generator are formed on a same die as circuitry of the link handshake state machine.
