摘　　要：介绍了两种针对HIRFL-CSR控制特点,自主开发设计的光纤通信适配器。包括设计思路、工作原理、硬件组成及应用范围。如何利用这两种光纤适配器远程控制具备RS232或RS485接口的仪器设备。在工程中应用这两种适配器和光纤替代RS485总线解决了通信干扰问题,满足了工程控制要求。We introduced two kinds of fiber adapters that apply to the engineering HIRFL-CSR Including design of two adapters, operational principle, and hardware construction, field of application. How to control equipments which have the standard RS232 or RS485 interface at long distance by two adapters. Replace the RS485 bus with the fiber and the 485-Fiber Adapter, solved the problem of communication disturb. The requirements of control in the national great science engineering HIRFL-CSR are fulfilled.
