An optical power meter (OPM) is a device used to measure the power of an optical signal, typically in fiber optic systems.
Components
- Sensor: Usually a photodiode, it detects the light signal and converts it into an electrical signal.
- Display: Shows the measured optical power, often in units like milliwatts (mW) or decibels (dBm).
- Calibration: Ensures accurate measurements by comparing the device’s readings with a known standar
