Abstract: Methods, architectures, circuits, and/or systems for tracking variations in the operating parameters of an optical or optoelectronic device are disclosed, as well as use of such variation data to monitor or control device functions and/or generate warnings and/or status flags. A method of tracking a variation in one or more operating parameters in an optical or optoelectronic device may include (i) monitoring one or more operating parameters of the device over time to determine values for each of the operating parameters, (ii) calculating the variation in each of the operating parameters as a function of time, (iii) comparing the variation to one or more predetermined thresholds, each threshold corresponding to an operational warning or alarm, and (iv) generating the operational warning or alarm when the variation exceeds the corresponding threshold.

Abstract: An optical and/or optoelectrical transceiver and system are disclosed that enable parallel transmission of data and management signals via an optical fiber without affecting data signal transmissions transmitted on the optical fiber. Furthermore, the present transceiver and system provide a fault diagnosis function for an optical fiber link. The transceiver and system generally comprise an interface, an intersecting transmission management unit, a driver, a management signal driving unit, an optical transmitter, an optical receiver, an amplifier, a management signal recovery unit, a management unit, and optionally, a power supply unit.
