| Zusammenfassung: | An optical transmission apparatus includes a multiplexing unit multiplexing signal light of a main signal, and dummy lights of odd channel and an even channel emitted using first and second dummy light sources, respectively, a detection unit detecting abnormality of the first and second dummy light sources, and a control unit performing addition control. The addition control includes control in such a way that dummy light of an even channel emitted using the first dummy light source is additionally multiplexed with the signal light, when no abnormality is found in the first dummy light source and an abnormality of the second dummy light source is detected, and that dummy light of an odd channel emitted using the second dummy light source is additionally multiplexed with the signal light, when no abnormality is found in the second dummy light source and an abnormality of the first dummy light source is detected. |
