DDM – Real-Time Optical Diagnostics

The module supports Digital Diagnostic Monitoring (DDM), which allows network administrators to monitor important operating parameters directly from the switch interface:

• transmitted optical power (Tx)
• received optical power (Rx)
• module temperature
• supply voltage
• laser bias current

This feature enables faster troubleshooting and better visibility of fiber network performance.
