Abstract
A design method for a quasi-coarse wavelength division multiplexing optical network is provided. A spectral grid of an optical channel has a pre-set fixed bandwidth, and the pre-set fixed bandwidth is at least 200 GHz. A modulation format of the optical channel is adaptively selected according to actual rate requirements and physical channel conditions, thus selecting an optimal modulation format achieve a tradeoff between the total cost of IP router ports and regenerators and the served number of traffic demand. The above technical solution effectively resolves the technical problems in the prior art of high construction costs and low spectral efficiency of elastic optical networks.
