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.
This reference is intended for preliminary fiber optic patch cord research. Compatibility, link budgets, connector types, polish, installation methods, test limits and applicable standards must be verified for the specific project.
