Does an adjustable light attenuator have a direction

Home / Does an adjustable light attenuator have a direction

Since an attenuator circuit consists solely of passive resistor elements, it is both linear and reciprocal. 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 device uses a single control line, with the voltage at that control determining the attenuation of the device (an "analog" attenuator!): Typical voltage control attenuators can provide attenuation from a minimum of a few dB to.

Attenuators

As the name implies, digital attenuators are controlled with a set of digital (i.e., binary) control lines. As a result, the attenuator can be set to a specific number of discrete values.

Attenuators

Attenuators weaken or attenuate the high level output of a signal generator, for example, to provide a lower level signal for something like the antenna input of a sensitive radio receiver. (Figure below)
