摘　　要：充分利用光纤的频带资源是降低光纤数据传输系统成本的重要途径,波分复用和时分复用是信道共享和有效利用的常用方法。通常,利用CPLD实现多路信号时分复用的方式较使用多个激光器产生多个波长的激光的波分复用方式有较大的成本优势,但后者更容易实现双向通讯。因此,将波分复用和时分复用结合复用的方式即可实现一种高速、双向、点到点的光纤数据传输系统。In this paper, the author analyzes that the full use of optical fiber bandwidth resources is the important way to reduce optical fiber transmission system costs, and WDM and TDM are the commonly-used methods to share the information effectively. Typically, as compared with laser with multiple wavelength through laser device, multi-channel signal TDM under CPLD has a greater cost advantage, and however, it is more easily for the latter to achieve two-way communication. Thus the combination of WDM and TDM is a way to achieve high-speed, two-way, point-to-point optical data transmission system.
