Object
column SNMPv2-SMIInteger32
The value of tmnxDDMRxOpticalPower indicates the current Received
Optical Power of the SFF in one tenths of a microwatt (uW).
If the SFF is externally calibrated, the objects
tmnxDDMExtCalRxPower4, tmnxDDMExtCalRxPower3, tmnxDDMExtCalRxPower2,
tmnxDDMExtCalRxPower1 and tmnxDDMExtCalRxPower0 affect the output
power calculation.
For example (internally calibrated SFF):
Using the SNMP value of 790, and using units of tenths of microwatt,
790 becomes 79 microwatts or 0.079 milliwatts. Converting to dBm:
10 x log10(0.079) = -11.0 dBm
