%X In order to improve the transmission bandwidth of digital image, the performance of f iber link, and the anti-interference ability of electromagnetic, a high speed optical f iber Transmission system for CCD image was designed in space CCD camera with a large f ield of view. First, the input rate was gained according to the characteristics of CCD imaging unit and the working environment of space camera in orbit, based on which, a 9-channel parallel high speed optical f iber transmission system for multi-channel CCD image was designed. Then, we expounded the system design idea and the principle of high speed serializer and optical module. Then, an error correction algorithm was proposed. And implementation method using very large scale integration (VLSI) was explained for the encoder. Finally, the experiments were performed for transmission system of the prototype in XX-X space multi-spectral camera. The results showed that the transmission system has a high reliability. The correcting algorithm has the characteristics of strong error detecting ability, less resource occupation and easier to be realized with hardware. The method is able to correcting 191 bit errors in 3043 Byte and meets the reliability of image Optical f iber transmission in space camera.
