KANALAUSGLEICH EINES OPTISCHEN WELLENLÄNGENMULTIPLEXSIGNALS |
摘要 |
The invention relates to methods and arrangements for channel balancing of a wavelenght division multiplexed optical signal. Channel balancing according to the invention is performed by using a resonator that provides a selection region in which a selected channel has a substantially increased power density relative to channels out of resonance. The selected channel is attenuated a desired amount, i.e. a desired amount of poer is removed therefrom, by adjusting the prperties of the selection region. In a preferred embodiment, attenuation is achieved by adjusting the selection region such that destructive interference is obtained for the selected channel in a fibre carrying the multiplexed optical signal. |
