Monitoring technology for active optical components

A diagnostic monitoring device comprising:

• a diagnostic monitor circuit within a cable, and 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;
• a microcontroller within the cable, and 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;
• generate a clock disable command in response to an instruction received from an external system;
• and
• transmit the clock disable command to the diagnostic monitor circuit;
• wherein the microcontroller further comprises a communications link for communicating with the external system external to the diagnostic monitoring device;
• wherein 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 being configured to disable the first clock or the first oscillator for at least a predefined period of time, thereby ceasing operation of the diagnostic monitor circuit.
