Method for optimizing the capacity of optical communication networks

摘要

The embodiments of the present invention describe a method for optimizing the capacity of an optical communication network that uses wavelength division multiplexing, wherein the spectral distribution of the signals intended to be transmitted over a plurality of channels is done dynamically through the use of a variable spectrum grid whose spectral spacings between two successive channels are determined based on the spectral width of said signals and in which dynamic filtering of said signals is carried out before their transmission in order to adjust their spectral width based on the available spectral space, and thereby reduce crosstalk between adjacent channels when the signals are transmitted.

1. An optical signal transmission device comprising means configured to:
determine the optimal spectral spacings between the various channels carrying optical signals intended to be transmitted as a function of the spectral width of said signals and the desired range present signals, establishing a special grid whose spectral spacings between two successive channels correspond to the previously determined spectral spacings, filtering said signals in order to adjust their spectral width as a function of the available spectral spacing and thereby to reduce crosstalk between adjacent channels when signals are transmitted.
