Fiber Optical Power Meter
Greenlee 450/460 optical power meter is used to measure the power in an optical signal. The term usually refers to a device for testing average power in fiber optic systems. Greenlee 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.
