Abstract:
1. A transmission apparatus, comprising: a first switch that switches an optical transmission path of a received light signal to one of a first path and a second path in the transmission apparatus; a photoelectric transducer that converts the light signal output from the first path or the second path into an electric signal; a second switch that provides the electric signal output from the photoelectric transducer to one of a third path and a fourth path; an electronic processing unit that is inserted into the third path and that performs processing to compensate for degradation of an optical transmission characteristic of the light signal on the optical transmission path, the electronic processing unit outputting compensation information; an optical characteristic compensation device that is inserted into the second path and that has set therein a compensation value based on the compensation information output from the electronic processing unit; and a controller that, when the first switch switches from the first path to the second path, sets the compensation value in the optical characteristic compensation device, and that performs control to switch, after setting the compensation value, the second switch from the third path to the fourth path.
