To improve the data output quality of multi-channel, high data rate and high transmission distance CCD system in a remote sensing camera, a kind of parallel fiber transmission system adaptive to multi-channel high-speed CCD image data is developed to apply to the space remote sensing camera. The fiber transmission channel with effective data rate of single port up to 1.28 Gb/s is designed and realized. Based on describing the thought of design and the structure of fiber transmission channel, the key technologies among the system, such as high-speed data interface and high-speed serial photoelectric interface are analyzed in detail. A TDICCD image data parallel transmission system with five channels based on fiber is developed, total effective data rate is up to 5.7 Gb/s. The experimental results indicate that the system works stable, high effetive,and no error code,which can meet the requirements of high-speed and far distance in the transmission of multi-channel CCD image data.
