Convert Power, dBm

WebMost displays of optical power are in dBm (deciBels/milliwatts). Decibels is a ratio of two power levels, one of which is considered the reference value. The db is a logarithmic scale. The m in dBm refers to the reference power which is 1 milliwatt. To convert between the raw hardware readings of .1 uWatts and dBm, use this formula:
