[0002] In the traditional Camera link image transmission system, the transmission medium between devices is directly connected by Cameralink cable. Due to the poor anti-interference performance of the Camera link cable and the short transmission distance (less than 10 meters), it cannot meet the long-distance requirements. distance transmission

In recent years, with the development of optical fiber interconnection transmission technology, basic (Base) Camera link image optical transceivers based on optical fiber transmission have gradually appeared, but they can only realize basic (Base) Camera link image transmission, and the transmission distance is short (about 300 meters), which fail to meet the long-distance transmission of long-distance camera link real-time images with medium configuration (Medium), full configuration (Full), and high bandwidth (85MHz) for engineering needs, and fail to meet longer-distance (100 kilometers and above) transmission
