Innovative Optical Attenuator Supports Long Operating Time

Toronto, Canada – GAO Fiber Optics ( has released its innovative variable optical attenuator intended for on-line testing. It assists in the maintenance of fiber optic systems as well as digital communication devices such as PHD or SDH or systems using analog modulation such as CATV. The attenuator has an auto-off function and is able to auto restore the attenuating value and steps when it is powered on next time.
GAO Fiber Optics’ variable optical attenuator, model A0610001, is used as a passive component to reduce the optical power of signals propagating through optical fiber. It uses a neutral density filter to achieve attenuation which is adjustable through the rotating dial on the keypad. The device features superior linearity, high accuracy and low insertion loss in regulating power and adjusts the amplitude of an optical signal to the desired level without distorting its waveform. This rugged attenuator operates in the wavelength range of 1260nm to 1650nm and displays attenuation values in either dB or dBm. Calibrated wavelengths including 1310, 1490, 1550, and 1625nm are available. It supports a long operating time of about forty hours when it is fully charged.
