Description of the invention: [Technical field to which the invention pertains] The present invention relates to an optical divergence network monitoring device and method, and more particularly to a monitoring device using a plurality of user terminals using a monitoring device at the machine room end. In order to achieve the goal of simultaneously identifying the obstacles and the location of the obstacles. [Prior Art] With the rapid growth of the global Internet, traditional networks have been unable to cope with the demand for the idling information transmission application caused by the communication revolution, and the maturity of the optoelectronic industry technology and the diversification of product applications are timely and eager to grow. The global Internet, high-quality multimedia network and the wide bandwidth required for various data communications' provide the best solution. Therefore, various optical network architectures have emerged one after another. Passive optical network (Passive) The Optical Network (PON) service system is the most optimistic. In order to meet the needs of the monitoring of its special network architecture in response to the large-scale use of this service system in the future, it is necessary to invent devices and methods that can easily monitor the divergent routes of the passive optical network. Passive optical networks have been difficult to perform optical fiber monitoring due to the innate architecture design of different routings. Previously, optical time domain reflectors (Optical Time D〇main Refleetome_ 〇TDR) were used. On the domain anti-(four) track, all the signals after the divergence are superimposed on the 'can't identify the right-new route; the scale decisive lake problem, there is an active identification component at the end of the divergent route, but it needs to cooperate with the communication network and the computer room. The control of the computer at the end often increases the complexity of the monitoring system; it also uses the long-distance displacement fiber-optic reflection unit as the identification component's, but because of the length of the divergent route, it is difficult to design and install; especially In this way, the optical time domain reflector is used as the monitoring subject. When the number of routing divergence increases, the dynamic range (Dynamic Range) and the event dead zone (2010) are limited by the optical time domain reflector. Therefore, the monitoring target is difficult to achieve. In addition, it is also useful for Tunable Laser light source, optical circulator, optical power - ten and then with the fiber grating detector (four) Qian Moga (four), touch) design, although the purpose of the obstacle can be measured When measuring the differences of light, it is impossible to show all the current status of the route, and the miscellaneous financial regulation of the laser is not switched. The more the number of divergence of the route is, the longer it takes; Applying this method to know the obstacles that occur - the divergent route 'can not know the location of the obstacle, there are still restrictions on the transfer. It can be seen from the above that the above-mentioned financial practices are still recorded, and they are not correct, but they are urgently needed to be improved. In view of the above-mentioned (four) way, the squadrons of the above-mentioned (four) methods, Lin Sisi made improvements and innovations, and after years of painstaking research, finally succeeded in researching and developing the invention of the dual-end monitoring device and method for the county network.

Cost and improve maintenance efficiency.
