Complete guide to optical attenuators: fixed, stepwise & continuous types. Learn gap-loss, absorptive & reflective principles plus attenuation calculations.
Optical attenuator
An optical attenuator, or fiber optic attenuator, is a device used to reduce the power level of an optical signal, either in free space or in an optical fiber. The basic types of optical attenuators are fixed, step-wise variable, and continuously variable.

Fixed Attenuators/Terminations
With the exception of the 75-ohm models, most fixed attenuators perform reasonably well above 2000 MHz. Please refer to data pages for actual performance characteristics.
Attenuation
Attenuation in optical fibers occurs when the light intensity is reduced as it propagates through the fiber. It is a type of optical loss and it limits the distance over which it can travel.
