A method of transmitting a concatenated signal consisting of at least two component signals over an optical network comprising at least three network elements (1, 2, 3, 7, 8, 9, 10) is disclosed in which at least two component signals are transmitted on at least two different wavelengths, and in which the component signals are assigned to the wavelengths for each section between two network elements (1, 2, 3, 7, 8, 9, 10) in such a way as to minimize differential delays between the component signals for a predetermined receiving location. Concatenated transmission capacity can be allocated even if it is no longer available on one wavelength as a coherent whole.
