Optical repeating apparatus, optical network system, optical network design supporting apparatus and design supporting method

摘要

The present invention relates to a technique suitable for the enhancement of efficiency of wavelength allocation in an optical network. A transmission capability for each of a plurality of wavelengths available in the optical network is calculated to allocate, to a recommendation optical transmission path in the optical network for a traffic demand from the external, a wavelength having a transmission capability corresponding to a total optics transmission distance of the recommendation optical transmission path on the basis of a result of the calculation. This enables considerably reducing the number of optical repeaters to be disposed, each of which has an electrical signal regeneration function in the optical network, thereby reducing the number of devices, dissipation power, installation area and others in the optical network.
