Is it normal for the optical power meter to display
Other general purpose light power measuring devices are usually called,, power meters (can be sensors or ), or lux meters. Most fiber optic signals fall well below 1 milliwatt, so you'll almost always see negative dBm values. 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. An optical power meter measures the strength of light traveling through a fiber optic cable, giving you a reading in dBm (decibels relative to one milliwatt). Every time you double (or halve) the power level, you add (or subtract) 3 dB to the power level.
