theRTLSBlog.com: Toronto, Canada – GAO Fiber Optics (www.GAOFiberOptics.com) has rolled out a handheld variable optical attenuator intended 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. It is used as a passive component to reduce the optical power of signals propagating through optical fiber. This innovative variable optical attenuator, model A0610001, utilizes a neutral density filter to achieve attenuation which is adjustable through rotating the dial on the keypad. It operates over the wavelength range from 1260nm to 1650nm and displays attenuation values in either dB or dBm. Calibrated wavelengths including 1310, 1490, 1550, and 1625nm are also available. The attenuator regulates power at superior linearity, high accuracy and low insertion loss and also adjusts the amplitude of an optical signal to the desired level without distorting its waveform. This rugged attenuator has an auto-off function and has the ability to automatically restore the attenuation value and step the next time it is powered on. In addition, it supports a long operating time of about forty hours on a single charge. Visit http://www.GAOFiberOptics.com for more information or to purchase this product online.
