Digital Diagnostics Monitoring

Digital Diagnostics Monitoring (DDM) maintains values for temperature, voltage, 
txbias, txpower and rxpower. In the display, the value is followed by the status. The 
status values are Normal, LowAlarm, LowWarning, HighAlarm and HighWarning 
(media vendor-supplied threshold values that are read from the media device). Low

The IEEE registered company ID

Media Part Number

The part number assigned to the SFP

Media Revision

Transceiver hardware version

Details

For ports with media that support DDM, a button will be available that 
displays a dialog with detailed information for the media in the port.

Temperature (C)

The measured temperature for the media in the port.

Voltage (V)

Internally measured supply voltage. The measured supply voltage for the 
media in the port.

Tx Bias (mA)

Measured transmitter laser bias current. The measured transmitter, laser bias 
current for the media in the port.

Tx Power (mW)

Measured transmitter laser output power. The measured Tx output power 
for the media in the port.

Rx Power (mW) 

Measured received optical power. The measured Rx optical power for the 
media in the port
