Arrangement for channel-dependent attenuation of multiple optical data channels signal level, has attenuating device in at least one optical path for attenuating signal component of corresponding path

摘要

Apparatus for channel-dependent attenuation of the level in optical data channels, has a filter device (1) which divides an input signal of the multiple data channels in a wavelength-dependent manner into at least two optical paths (3,4) and an attenuation device (2) in at least one of the optical paths (4) which attenuates the signal component of the corresponding paths. The paths (3,4) and signal components down-stream of the attenuation device (2) are then again combined.
