High-definition SDI (Serial Digital Interface) digital video signal optical fiber transparent transmission device

The invention relates to a high-definition SDI (Serial Digital Interface) digital video signal optical fiber transparent transmission device. The high-definition SDI digital video signal optical fiber transmission device comprises an SDI optical fiber transmission sending end and an SDI optical fiber transmission receiving end, wherein the SDI optical transmission sending end is used for converting an SDI high-definition digital video signal input by a user into an optical signal through signal processing, and transmitting the optical signal through an optical fiber medium; the SDI optical fiber transmission receiving end is used for receiving a high-speed serial optical signal transmitted by n optical fiber, reducing the optical signal into the SDI high-definition digital video signal through the signal processing, and outputting the SDI high-definition digital video signal to a video receiving end. The high-definition SDI digital video signal optical fiber transparent transmission device is compatible with the transmission of various SDI digital video formats, and has the advantages of high transmission instantaneity, large transmission bandwidth and high electromagnetic interference resistance.
