dB Meter
The dB meter is used to determine the stability or fluctuations of the optical power over a large dynamic range with high accuracy and measurement speed. A fiber-coupled, power-stabilized 1.55µm laser diode is built into the device to enable simple and quick testing of passive fiber optic components or local fiber loops. Alternatively, light from external light sources in the wavelength range 780nm-1650nm can also be used.
