    DDM stands for Digital Diagnostic Monitoring. In optical modules, DDM enables real-time monitoring of critical parameters such as optical output power, input power, laser bias current, module temperature, and supply voltage. Digital Diagnostics Monitoring (DDM), also known as Digital Optical Monitoring (DOM) or Diagnostic Monitoring Interface (DMI), is a standardized feature defined by SFF-8472 that allows network devices to monitor real-time optical transceiver parameters such as temperature, voltage, transmit power. The introduction of Digital Diagnostic Monitoring (DDM), often referred to as Digital Optical Monitoring (DOM), fundamentally transformed this paradigm, converting the passive transceiver into an intelligent, active network component. It refers to the function that allows network operators to access real-time operational information from optical transceivers. Most of the transceivers in use today feature the DDM function. Although there are some related articles, when you.
