What does Variable Optical Attenuator dB mean
A Variable Optical Attenuator (VOA) is a controllable device used to reduce the optical power traveling through a fiber or free-space optical path. The basic types of optical attenuators are fixed, step-wise variable, and continuously variable. They do not modify the signal content, wavelength, or transmission path. Attenuators are.

Function of Variable Optical Attenuator
Optical attenuators can take a number of different forms and are typically classified as fixed or variable attenuators. What's more, they can be classified as LC, SC, ST, FC, MU, E2000 etc. according to the different types of connectors. Fixed optical attenuators used in fiber optic systems may use a variety of principles for their functioning. Preferred attenuators use either doped fibers, or mis-aligned splices, or total power since both of thes.

Graded Optical Attenuator
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. Sharp bends stress optic fibers and can cause losses. If a received signal is too strong a temporary fix is to wrap the cable around a pencil until the desired lev.

Disadvantages of variable optical attenuators
Such devices can be sensitive to: modal distribution, wavelength, contamination, vibration, temperature, damage due to power bursts, may cause back reflections, may cause signal dispersion etc. A Variable Optical Attenuator (VOA) is a controllable device used to reduce the optical power traveling through a fiber or free-space optical path. Think of it as a permanent filter. Once it is installed in your link, the amount of signal reduction stays exactly the same. The attenuator circuit will allow a known source of power to be reduced by a predetermined factor, which is usually expressed as decibels. Unlike fixed attenuators (which have a set value like 5dB or 10dB), a VOA allows for continuous or incremental adjustment of attenuation, typically ranging from 1dB to 30dB or even 60dB.
