Description
Technical Field
The present disclosure relates to the field of Passive Optical Network (PON) technologies, and in particular, to a method and an apparatus for determining a Network fault, and a non-volatile storage medium.
Background
Fig. 1 is a structural diagram of a PON, which is a current mainstream broadband deployment architecture and mainly includes an Optical Line Terminal (OLT), an Optical Network Unit (ONU) at a subscriber side, and an Optical Distribution Network (ODN). The ODN is an optical transmission physical channel between the OLT and the ONU, adopts a passive optical access technology, and mainly comprises passive optical fibers and passive equipment such as an optical fiber cable, an optical connector, an optical splitter, a wiring box, a connector box and the like; each node device is a dummy resource and does not have the characteristics of management and maintenance. The Optical fiber line between the OLT and the distribution box is a trunk Optical fiber line, the Optical fiber line between the distribution box and the last Optical splitter (OBD) is called a branch Optical fiber line, and the Optical fiber line between the last OBD and the ONU is called an in-house Optical fiber line.
The PON network has the outstanding characteristic that outdoor active equipment is eliminated, so all signal processing functions are completed in a local machine room and user equipment in the home. Since the ODN of the pon does not include any electronic device or electronic power supply, it cannot be monitored and managed by an Element Management System (EMS). The existing PON network management has low accuracy in passive network fault positioning, and is easy to cause misjudgment and omission. One of the existing passive network fault positioning methods of the PON network management system is to use an external device to determine the fault position by manually testing and checking the passive network section by section on site; the other method is to adopt an Optical Time Domain Reflectometer (OTDR) to test the fault position on site; the first method has too long maintenance time; although the second method can determine the fault position more accurately, the OTDR adopted in the second method is high in price, so that the second method is difficult to popularize on a large scale; and the ODN network maintenance is generally carried out by different post maintainers in charge of different paragraphs, and the manual detection is easy to misassign posts due to fault location errors, so that the working efficiency is low. Therefore, in the prior art, when a fault that an optical cable is disconnected occurs, the fault position cannot be accurately located, and whether a fault of a single user or a mass-sending fault occurs cannot be judged.
In view of the above problems, no effective solution has been proposed.
