Abstract
An optical transmission system () alters quantity of incident light by reflecting an optical signal by a micro mirror () to enter an optical fiber () and by controlling an angle of the micro mirror (), so that attenuation of the optical signal is controlled. An optical filter () is disposed between the micro mirror () and the optical fiber (), for correcting a relationship between a control angle or control voltage of the micro mirror () and attenuation of the optical signal to be close to a linear relationship.
