Our 10G SFP+ ER module supports Digital Diagnostic Monitoring (DDM) per SFF-8472 Rev.11. It allows administrators to monitor critical performance metrics in real time through the switch’s interface or SNMP:
Monitored Parameters:
Transmit optical power (Tx)
Receive optical power (Rx)
Module temperature
Laser bias current
Supply voltage
First, clean the fiber end faces. If issues persist, check fiber length and splice loss, then compare DDM readings to spec limits.
