摘要
本论文的课题为电子科学研究院“十五”重点预研项目“波控信号光纤传输系统”。
系统设计中运用了数字通信和光纤通信技术实现对四十路并行波控数字信号的复用/解复用、光纤线路码CIMT的编解码和高速数字信号的光纤传输。
作者完成的主要工作有：
1． 根据系统性能要求，确定设计方案，设计出了硬件电路，包括：信号源接口电路、发射电路、接收电路以及以太网接口电路，并进行了调试；
2． 对系统的可靠性作了无码间串扰和有码间串扰的误码率测试，并同理论计算值进行了比较，对结果进行了分析；
3． 对系统的稳定性作了传输数字视频信号的测试实验。
系统误码率性能超过课题设计的目标要求10-9，达10-10/10-12；通过了10Mbps以太网视频数据信号传输的实时测试；通过了有关部门的系统性能评估。
This paper is related with the project : "The optical fiber transmission system of the wave-controlled signals" of the tenth five-year plan conducted by the Researching Institute of Electronics and Science of China .
The system has the function of multiplexing and de-multiplexing of 40 channels' parallel wave-controlled digital signals、coding and decoding of optical fiber line code CIMT and optical transmission of high bit rate digital signal.
The following work has been done.
1 Scheming the system based on the system requirement, designing hardware circuits including signal source interface circuit、transmitting circuit、receiving circuit and Ethernet interface circuit, debugging them.
2 Testing the BER with and without inter-symbol interference , analyzing the testing result.
3 Testing system's stability by transmitting digital video signal .
The system has excellent BER performance of 10～(11), which is much better than required; that is 10～(-9) ;what's more , the system has been tested by the experiment of transmitting 10Mbps Ethernet video data stream real time and approved by relative authorities .
