Home / What is the working principle of an adjustable mechanical optical attenuator
The working principle of MEMS VOA is based on the mechanical movement of the micro-mirror or micro-shutter. An optical attenuator is a passive optical device that has a function opposite to that of an optical amplifier. The attenuator circuit will allow a known source of power to be reduced by a predetermined factor, which is usually expressed as decibels. New for June 2019: mechanically variable attenuators are often used in lab equipment, so that one unit can serve many purposes (instead of a drawer full of fixed attenuators). They are continuously adjustable (using a thumb wheel or a screw head for examples), and consume zero DC power.
This article will delve into the working principle of the SFP dimmable optical attenuator and discuss its practical application in many fields, taking you to appreciate the charm of this precision device.
