摘　　要：介绍了一种基于大规模CPLD实现的8路时分复用光纤传输系统的原理,并详细说明了利用编/解码芯片和大规模CPLD实现时分多路传输系统的方法.为了实现多路数字信号传输,系统采用了TDM和WDM技术,信道中两路光载波信号分别为850nm和1310nm.通过试验,验证了方案的可行性和先进性.This paper introduces the principle of a fiber optic communication system of time division multiplexer based on large scale CPLD, and presents the method of implementing encoder/ decoder and large scale CPLD. The TDM and WDM technology is used for transmitting muli-digital-signals and the two optical carriers are 850 nm and 1310 nm respectively. The feasibility and advancement of the scheme are validated through testing.
