  • Standard optical attenuator specifications in the Democratic Republic of Congo

    Standard optical attenuator specifications in the Democratic Republic of Congo

    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. ApplicationsOptical attenuators are commonly used in, either to test power level margins by temporarily adding a calibrated amount of signal loss, or installed permanently to properly match transmitter. The power reduction is done by such means as absorption, reflection, diffusion, scattering, deflection, diffraction, and dispersion, etc. Optical attenuators usually work by absorbing the light, like absorb extr. Optical attenuators can take a number of different forms and are typically classified as fixed or variable attenuators.
