    The design method of a fiber transmission remote image acquisition system based on a high resolution EXview CCD is presented and the main units in the system are introduced in detail. The system utilizes a special IC to achieve time driving and takes double Complex Programmable Logic Devices(CPLDs ) to complete the logic control. In order to improve dynamic ranges, it uses a 16 bit high resolution Digital to Analog Converter(ADC) to digitalize video signals. Furthermore, the system can transfer mass video data in long-distances based on the TLK1501,and can perform data terminal collection with a computer by a USB. Finally, two important parameters: dynamic range and the system gain are estimated in an experiment. The system offers its specifications are a resolution of 1.4 million pixels, digitizer type of 16 bits, and remote transmission less than 30 km. Moreover, its dynamic range is 60-65 dB,system gain is 2.34 ADU/e-. Experiments show that designed system is fit for the science research which demands for the best quality mentioned above.
