Overview – Variable Optical Attenuator
This handheld variable optical attenuator is a passive component used to reduce the optical power of signals propagating through optical fiber. The attenuator is an invaluable testing instrument used for on-line testing and maintenance of fiber optic systems as well as digital communication system devices such as PHD or SDH or systems using analog modulation such as CATV.
This compact variable optical attenuator regulates power with superior linearity, high accuracy and low insertion loss. It adjusts the amplitude of an optical signal to the desired level without distorting its waveform. The device utilizes a neutral density filter to achieve attenuation which is adjustable through the rotating dial on the keypad. The device works at the wavelength range of 1260nm to 1650nm and displays attenuation values in either dB or dBm.
The attenuator has an auto-off function as well as the ability to auto restore the attenuating value and steps the next time it is powered on.
