Optical Attenuator

The RS-3A Adjustable Digital Light Attenuator is mainly used for the attenuation of continuous optical signal power, whose core components are imported high-performance ones to enable it to have the ability of quick regulation of attenuation value with good linearity, high accuracy, low insertion loss and attenuation locating, etc. The instruments are widely applicable for optical cable construction and maintenance, fiber optic communication, fiber optic sensor and CATV, etc.
The body of RS-3A series products is designed to the demand of human engineering. With advanced cold molding process applied, the instrument looks attractive in shape, and is durative, reliable, easy to use, and suited to several working atmospheres.
