介绍利用波分复用技术（WDM）设计了一种低成本光纤双向视频和数据信号传输系统，实现了在一根单模光纤中传输数据信号和视频信号。视频信号传输采用基带直接强度调制（D-IM）技术，而数据信号传输利用频移键控（FSK）技术。该系统实现了无中继传输距离大于6km，适合中短距离视频、数据的传输，设计方案简易、成本低廉、图像质量良好成为该系统的主要特点。

The paper introduces the design of a low-cost fiber-optic two-way video data signal transmission using WDM technology System to realize the transmisskm of data video signals ha a single-mode fiber. Video signal transmission adopts baseband direct strength Modulation Teclmology, and the dam signal transmission adopts frequency shift keying technology. The system can achieve no relay transmission with distance larger than 6km, and is suitable for short-range video, data transfer. The system has the characteris- tics of simple design, low cost and good image quality
