This article gives the transmit power value of the SFP plugged into Line 1 and Line 2,
read from the Digital Diagnostic Monitoring (Unit = dBm). The actual Transmit Power
in dBm or mW can be obtained by applying the following formula to the returned
value:
Tx_Pwr(mW) = AV/10000
Tx_Pwr(dBm) = 10xlog(AV/10000)
Parameter Meaning Format
AV Article Value Unsigned word (16 bits)
For example:
A listing of the ms430580mMesrportaTxPower outputs the following:
***** SNMP QUERY STARTED *****
1: ms430580mMesrportaTxPower (integer) 30
***** SNMP QUERY FINISHED *****
The value returned from the SFP in Line 1 is: 30.
So applying the formula: Tx_Pwr(mW) = 30/10000
Gives an actual value of: 0.003mW
And applying the formula: Tx_Pwr(dBm) = 10xlog(30/10000)
Gives an actual value of: -25.23dBm
