With the rapid development of the optical fiber network , the complexity of network increase the work of management and maintenance become much more heavy in the physical network of optical fiber , the fiber lines appear malfunction frequently , such as broken by somebody , infiltrated by water etc . the malfunction will not interrupt the transmitting signal quickly , but we must konw the place and type of the malfunction , to avoid to lose service and device . so researching real - time monitor and test the fiber in optical fiber network become a very important problem and has practical value very much 随着光纤网络的快速发展,网络的复杂性日益提高,光纤物理网络的管理、维护工作日益繁重,作为光传输主体的光缆线路常有缆线接续不良、水气渗入光纤芯线、接头接点不良和光缆被挖断等故障。通常情况下,故障并不会立即引起光缆传输信号的中断,而是导致光缆系统缓慢劣变,但对其修复又必须在很紧急的情况下进行。
