When a failure occurs in operational transmission multiplexing transponders (6-1 to 6-N), a wavelength multiplexing optical transmission system carries out selection switching control on N×1 optical switches (5-1 to 5-m) and (N+1)×1 optimal switches (11-1 to 11-m) to transmit a wavelength-multiplexed light signal by using reserve transmission and reception multiplexing transponders (6-R and 10-R), thereby sidestepping the failure. |
