Does an optical power meter have a positive value for optical attenuation
Although meters measure a negative number for loss, convention has us saying the loss is a positive number, so we say the loss is 3. 0 dB when the meter reads – 3. The “m” in dBm refers to the reference. Typical power levels measured by an optical power meter: Telecom transmitters: 0 to +10 dBm (1 to 10 milliwatts), Receivers: -30 dBm (1 microwatt) DWDM systems with fiber amplifiers: +10 to +20 dBm (10 to 100 milliwatts), Receivers: -20 to -30 dBm (1-10 microwatt) Data links and LANs: 0 to -10 dBm. Actual optical attenuation = Upstream optical power on one side of the test point - Upstream optical power on the other side of the test point. It should be noted that decibel milliwatts less than 1mw are negative values. In addition to measuring optical power, optical power meters can also be used with light sources to measure optical loss.
