Does an optical power meter measure sensitivity
Optical power meters typically use semiconductor detectors since they are sensitive to light in the wavelengths and power levels common to fiber optics. An optical power meter (OPM) is a device used to measure the power in an optical signal. A successor and direct replacement for the N7748A, it continues the optical performance level of the 81634B modules. Optical power is based on the heating power. Unlike with a standard industry optical power meter, using Tolicore's high-sensitivity optical power meter, you can see femtowatt-level signals, and you can see them with a good signal-to-noise ratio.

Can an optical power meter measure the signal-to-noise ratio
OSNR, or Optical Signal-to-Noise Ratio, measures the ratio of signal power to noise power in an optical system, typically expressed in decibels (dB). The dominant noise in long-haul systems is amplified spontaneous emission (ASE) introduced by optical. Signal-to-noise ratio (SNR or S/N) is a measure used in science and engineering that compares the level of a desired signal to the level of background noise. A ratio higher than 1:1 (greater than 0 dB). The quality of optical and other measurements is often characterized by a signal-to-noise ratio (SNR, S/N ratio). TIA standard test FOTP-95 covers the measurement of optical power. Optical power is based on the heating power.

The optical power meter measures
An optical power meter (OPM) is a device used to measure the power in an optical signal. The term usually refers to a device for testing average power in fiber optic systems. Other general purpose light power measuring devices are usually called radiometers, photometers, laser power meters (can be photodiode sensors or thermopile laser sensors), light meters or lux meters. A typical optic. SensorsThe major types are (Si), (Ge) and (InGaAs). Additionally, these may be used with attenuating elements for high optical power testing, or wavelengt. A typical OPM is linear from about 0 dBm (1 milli Watt) to about -50 dBm (10 nano Watt), although the display range may be larger. Above 0 dBm is considered "high power", and specially adapted units may measure u.
