Optical transmission system and adjustment method

Abstract

An optical transmission system including: an optical switch that includes a plurality of ports, outputs an optical signal input from any one of the ports from a different one of the ports, and acquires transmission path information on the basis of the optical signal input to the port; a plurality of dispersion compensation units that compensate for quality of the optical signal output from the optical switch and input the optical signal with the compensated quality to the optical switch; an α parameter measurement unit that acquires an α parameter indicating a chirp level on the basis of the optical signal with the compensated quality; and a control unit that performs correction of the α parameter or adjustment of a dispersion compensation amount in a case where a condition indicating that a problem that is attributable to the α parameter has occurred is satisfied on the basis of a cumulative wavelength dispersion amount or a transmission distance obtained on the basis of the transmission path information and the α parameter.
