Despite advantages of distributed fiber optic sensor systems, the stability, reliability and limitation of physical parameters detected by the systems are still the bottlenecks of the applications in industrial control fields. In this paper, we compare different structures of fiber optic sensor networks based on special needs for manufacturing control and monitoring. A double-bus fiber optic sensor network directly used in industrial scene is presented. The multiplexing methods, such as time division multiplexing, frequency division multiplexing and code division multiplexing are analyzed. The result demonstrates that the double-bus fiber optic sensor network is adapted to use as manufacturing control systems in industrial environment, which offer low crosstalk levels, high signal to noise ratio and low optical path loss.
