Abstract

본 발명은 광 신호의 왜곡을 보정하기 위한 2x2 광 스위치를 이용한 광 시간 역다중화 장치에 관한 것으로, 일측 입력단에 다중된 광신호를 입력받고, 타측 입력단에는 광 신호의 DC 광과 같은 세기의 DC 광원을 입력받아 제어단의 제어 신호에 의해 입력된 광 신호를 역다중화하여 출력하는 다수개의 2x2 광 스위치를 구비하여 광 시간 역다중화시 왜곡을 보정하여 광신호의 왜곡으로 인한 송수신 감도의 열화를 줄일 수 있는 효과가 있다.The present invention relates to an optical time demultiplexing apparatus using a 2x2 optical switch for correcting distortion of an optical signal, and receives an optical signal multiplexed at one input terminal and a DC light source having the same intensity as the DC light of the optical signal at the other input terminal. Equipped with a plurality of 2x2 optical switch to demultiplex and output the optical signal input by the control signal of the control stage to correct the distortion during optical time demultiplexing to reduce the degradation of transmission and reception sensitivity due to distortion of the optical signal It has an effect.
