<p>The present invention discloses an optical switch system and a feedback control method of signal light. The optical switch system includes an input fiber, an output fiber and an optical output control module, and further includes a semi-transmissive semi-reflective module, an imaging module, a judging module and a control module, where the semi-transmissive semi-reflective module is set in a signal light propagation path of the optical switch system and configured to intercept, in a transmission manner, test light that is the same as the signal light with respect to the propagation path and output after being modulated by the optical output control module; the imaging module is configured to acquire the test light, generate corresponding initial optical path information and sampled optical path information in sequence, and transfer the initial optical path information and the sampled optical path information to the judging module in sequence; the judging module is configured to record the initial optical path information, and compare the sampled optical path information with the initial optical path information; and the control module is configured to control the optical output control module according to a comparison result. The present invention further provides a feedback control method of signal light. Compared with the prior art, the present invention greatly reduces a cost.</p> |
