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.
CONSTRUCTION AND WORKING
- A typical optical power meter consists of a calibrated sensor, measuring amplifier and display.
- The sensor primarily consists of a photodiode selected for the appropriate range of wavelengths and power levels.
- On the display unit, the measured optical power and set wavelength is displayed.
WHAT WE OFFER
- A wide range of power measurement accuracy from +26dBm to -70dBm.
- A wide range of standard wavelengths like 850nm, 1300nm, 1310nm 1490nm 1550nm 1625nm 1650nm.
- A wide range of resolution from 0.1dB to 0.01dB and even beyond as per requirement.
- Measuring the absolute power in a fiber optic signal. Although, for this application, the power meter needs to be appropriately calibrated at the estimated wavelength.
- To measure the optical power margin.
- Measuring the optical loss in a fiber, in combination with a suitable stable light source. Since this is a relative test, accurate calibration is not a particular requirement, unless two or more meters are being used due to distance issues.
