Professional single fiber multi-service BIDI 12G SDI Fiber Optic FD2917B，Optical signal transmission system designed based on broadcast-grade 12G SDI signals. The input SDI signal is adaptive, the output is synchronized with the input and supports the Relock function. The equipment has built-in SDI signal equalization, SDI serial clock recovery and line driver, and the signal quality complies with broadcast and television standards. It can transmit signals such as gigabit network, RS232, RS422/RS485, GPIO, and audio while transmitting 12G  SDI. The equipment adopts a single-mode single-fiber design with a standard transmission distance of 20KM. The corresponding modules of different distances can be replaced at will according to different application scenarios. It can be widely used in professional SDI video signals such as UHDTV/FHDTV/HDTV/SDTV, especially suitable for various engineering project applications of fiber optic mixed signal transmission.
