Abstract:
1. An optical transmit and receive circuit comprising the following: a first electro-optic transducer; a first electro-optic transducer driver coupled to the first electro-optic transducer so as to control optical signals emitted by the first electro-optic transducer; a first optoelectronic transducer; a first post-amplifier coupled to the first optoelectronic transducer so as to amplify electrical signals received from the first optoelectronic transducer; a second electro-optic transducer; a second electro-optic transducer driver coupled to the second electro-optic transducer so as to control optical signals emitted by the second electro-optic transducer; a second optoelectronic transducer; a second post-amplifier coupled to the second optoelectronic transducer so as to amplify electrical signals received from the second optoelectronic transducer; a control module communicatively coupled to both the first and second electro-optic transducer drivers, the control module configured so as to control transmit operational behavior of the first and second electro-optic transducers, and communicatively coupled to both the first and second post-amplifiers, the control module also configured so as to control receive operational behavior of the first and second optoelectronic transducers; and a multiplexer configured to periodically sample signals from first and second sensors that sense characteristics of the first and second electro-optic transducers, respectively, wherein the control module is configured to control transmit operational behavior of the first and second electro-optic transducers based at least in part on the periodically sampled signals from the first and second sensors.
