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.

Fiber optic attenuators are passive devices used to reduce the power or intensity of an optical signal in a fiber optic communication system. In addition, the system margin needs to be factored in—this covers fiber bending loss and. Assemble all necessary tools and equipment, such as a fiber cleaver, fusion splicer, optical power meter, and connector cleaning tools.

An optical attenuator, or fiber optic attenuator, is a device used to reduce the level of an optical, either in free space or in an. To reduce the signal farther down the fiber path, an optical attenuator using absorptive or reflective techniques would be more suitable. Transmitter power (TP) = 3dBm Receiver maximum optical input power (MP) = -6dBm Total losses (TL) = 5dB Minimum attenuation required = MP + TL – TP = -6dBm + 5dB – 3dBm = – 4 dB At a minimum, a 4 dB attenuator is required.

Optical attenuators are commonly used in fiber-optic communications, either to test power level margins by temporarily adding a calibrated amount of signal loss, or installed permanently to properly match transmitter and receiver levels. The power reduction is done by such means as absorption, reflection, diffusion, scattering, deflection, diffraction, and dispersion, etc.
