Optical Fiber Applying to Measuring and Controlling Systems

The application of conventional cable is limited by its weak immunity to electromagnetic interfering,large transmission loss and low communication rate.Optical fiber has many advantages comparing to conventional cable.Applications of optical fiber transmission system in measuring and controlling systems to strong radiation system such as nuclear experiment test and laser system are summarized,showing that optical fiber can do solve the problems of conventional cable in transmission.The application status of optical fiber transmission system is analysed,especially the analog optical fiber transmission system.It is pointed out that,for wider use of optical fiber transmission system,simple,practical and low cost optical fiber transmission modules are needed to develop.
