Description
Optical Attenuators are like sunglasses, protecting your eyes from strong light by absorbing excess light energy. Fiber optic attenuators, like sunglasses, protect optical fibers by working in a specific wavelength range. The criteria for a good fiber attenuator is to replace the reflective fiber by absorbing additional fiber. Because in the optical fiber communication, it is necessary to use a lower optical power without damaging the optical fiber attenuator.
