摘　　要：光纤弯曲时会产生功率损耗,并从弯曲处辐射出来。在同一根光纤的两端施加合适的光纤弯曲,高灵敏度的光电检测器检测弯曲辐射功率变化,在不中断通信条件下达到光纤对线的目的。低耗高效的嵌入式系统实现数据的采集和处理;主机和干扰夹持器无线连接,便于单人操作。Bending fiber causes power loss, which eradiates from the bending area of the fiber. Since high sensitive photodetector is able to detect the subtle bending power change when some appropriate bend is applied on two ends of a fiber, it can be used for allocating fiber's two terminations without requiring the expense and labor of a fiber termination. The embedded system described in this paper, is a low power loss, high efficient device with data collection capability. Its wireless connection between host and interference holder makes convenient for individual operation.
