Abstract
A method () of controlling compensation of chromatic dispersion in an optical transport network. The method comprises determining () whether a residual dispersion, RD, of a first path () within the network is within a defined RD range and if the RD of the first path is outside the defined RD range the method comprises identifying () a first tuneable dispersion compensation module, TDCM, crossed by the first path (), configured to apply a respective value of dispersion compensation. The method also comprises determining () a different value of dispersion compensation to be applied by the first TDCM to bring the RD of the first path within the defined RD range; if () the first TDCM is crossed by at least one other path (), checking () that the respective RD of said at least one other path is within a respective defined RD range for said different value of dispersion compensation; and generating () a control signal comprising instructions configured to set the first TDCM to apply said different value of dispersion compensation.
