Troubleshooting Fiber Optics Issues | REAL LAB EXAMPLES | DOM - Digital Optical Monitoring

The Digital Diagnostic Monitoring function is a tool for the engineers to monitor the status of the optical transceiver in real time. With this feature the engineer can monitor the various parameters of the optical transceiver like the temperature, power voltage, optical laser bias, TX (transmit) and RX (receive) power. Literally, this feature can provide even the tiniest details of the optical transceiver in real time without powering of or configuring the device. However, the Digital Diagnostic Monitoring feature has some more tricks in its sleeve. The feature also offers a complex system of programmed alarms and alerts which alert the host device when a particular parameter is beyond the default or preconfigured threshold. With this, DDM / DOM can allow the user to isolate the fault and predict failures much earlier and easier.
