Attenuators are usually passive devices made from simple voltage divider networks. Switching between different resistances forms adjustable stepped attenuators and continuously adjustable ones using potentiometers. A 3 dB pad reduces power to one half, 6 dB to one fourth, 10 dB to one tenth, 20 dB to one hundredth, 30 dB to one thousa.

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. The power reduction is done by such means as absorption, reflection, diffusion, scattering, deflection, diffraction, and dispersion, etc.

Most fiber-optic attenuators exhibit a relatively high return loss (at least several dozens of decibels), i. For single-mode devices, the insertion loss can not depend on the direction of propagation, as long as no non-reciprocal parts are used, as e.

In practice, you simply insert an attenuator between two fiber connectors or within a patch panel port. Optical attenuators serve a deceptively simple function-reducing signal power to prevent receiver saturation-yet their proper installation demands attention to details that many technicians underestimate. Match the fibre type (single-mode or multi-mode) with the correct connector type (SC, LC, FC, etc.
