Optical Unit: dB and dBm

 

dB is a relative unit that represents a multiple. The specific formula is 10log (multiple), such as 10dB for 10 times and 30dB for 10^3 times. dBm is an absolute unit, which is the unit of power as mw and w. The specific formula is 10log (P/1mw). So 0dBm is 1mw and 10dBm is 10mw. Here are the base 10 logarithms.
