What dB is considered normal for a light power meter
The normal value of an optical power meter is 12dbm. An optical power meter is an instrument used to measure the absolute optical power or the relative loss of optical power passing through a section of optical fiber. ” Loss is a negative number (like –3. The dBm scale is logarithmic, meaning a small numerical change represents a large change in actual light power. Above 0 dBm is considered "high power", and specially adapted units may measure up to nearly + 30 dBm ( 1 Watt). Engineers use the decibel-milliwatt (dBm) to quantify the absolute.
