Monitoring technology for active optical components
A diagnostic monitoring device contains a diagnostic monitor circuit configured to monitor analog diagnostic monitoring information, and configured to convert the analog diagnostic monitoring information to digital diagnostic monitoring information, the diagnostic monitor circuit comprising a first clock or a first oscillator. The diagnostic monitoring device further contains a microcontroller comprising a register map, wherein the microcontroller is configured to receive the digital diagnostic monitoring information, store the digital diagnostic monitoring information in the register map, and provide a clock disable command to the diagnostic monitor circuit. The microcontroller further comprises a communications link for communicating with an external system external to the diagnostic monitoring device. The diagnostic monitor circuit is configured to receive a clock disable command from the microcontroller, and in response to receiving the clock disable command, the diagnostic monitor circuit is configured to disable the first clock or the first oscillator.
