Abstract:
    A light beam (LS), which is used to transfer a wavelength multiplex signal (WDMv), is guided to a Bragg grating (BG) by means of an adjustable mirror (MR1). According to the angle of incidence of the light beam on the longitudinal axis (LA) of the Bragg grating (BG), various transmission characteristic lines having different gradients (m0 - m4) are obtained. As a result, scattering of the wavelength multiplex signal (WDMv) can be compensated. A second controllable mirror (MR2) enables the damping to be adjusted. A control device (RE) causes the scattering to be corrected in a rapid manner after the data signals are connected/or disconnected.
