摘　　要：介绍了一种短距离光纤传输系统,并成功地用于OSMAR2000的发射机监控系统中;系统采用光纤作为传输介质,因而具有较强的抗电磁干扰能力,同时由于系统采用了DSP作串行数据的发射和接收,因而具有可靠性高、数据处理能力强和串行波特率设置灵活等特点,能适应不同串行传输速率的需求,满足一般短距离的数据传输需求,可应用于某些人工不宜到达危险地方和较强电磁干扰的环境中,具有广阔的应用前景。A short--range optical--fiber communication system is introduced, it can be successful applied to the monitor system for the transmitter of the OSMAR2000. Because of using optical-fiber, the system is immune from electromagnetic interference, While t he DSP is used in this system, it makes high reliability, the powerful data processing function and flexible design for baud rate of serial port, and fits in with the needs of different transmission rate of serial port, And It meets the requirement of the short--range data transmission in strong electromagnetic interference fields and some dangerours places unaccessible by human. Therefore, it has a great potential in the future.
