Abstract
An optical transmission network includes a first dispersion compensator arranged in a maximum dispersion span having a maximum dispersion value and searched out from within a maximum dispersion route having a maximum dispersion value from among routes of non-regeneration intervals within which a dispersion value before dispersion compensation does not satisfy an upper limit of a dispersion tolerance, and a second dispersion compensator arranged in a maximum dispersion span having a maximum dispersion value searched out from within a maximum dispersion route having a maximum dispersion value from among the routes when a dispersion compensator is successively arranged until a route of a non-regeneration interval within which a dispersion value of a certain channel does not satisfy the dispersion tolerance does not remain any more based on the dispersion value after the dispersion compensation with respect to the searched out maximum dispersion span. The dispersion compensation amounts of the first and second dispersion compensators are such that, when the dispersion compensation amount of the maximum dispersion span in which the first and second dispersion compensators are arranged i…
