Power Conversion
mW to dBm Conversion Calculator
dBm is a unit of level used to indicate that a power level is expressed in decibels with reference to one milliwatt (1 mW) as a reference point. In order to work with such a wide range of values, optical power is often represented on logarithmic scale as dBm.
Use the calculator to see the correct conversion from mW to dBm.
Enter power in milliwatts or decibel-milliwatts for the calculator conversion.

Fiber Optics Calculations
Insertion loss formula
In fiber optics, insertion loss (IL) is the loss of optical power caused by adding a passive component like a patch cord, splitter or WDM in your network. For convenience, decibels (dB) are typically used.
The formula for insertion loss is given by:
