Method and system for positioning fault of optical fiber behind optical splitter in passive optical network (PON)

The invention discloses a method and a system for positioning a fault of an optical fiber behind an optical splitter in a passive optical network (PON). The method includes the following steps: when a downward branch optical path below a PON port breaks down, an optical time domain reflector (OTDR) is used for inputting downward test light to the PON port, the downward test light is combined with downward service light and then transmitted, and the OTDR is used for collecting the reflection curve of the downward test light and regarding the reflection curve as a test curve; the reflection curve of the downward branch optical path below the PON port when the downward branch optical path does not break down is regarded as a reference curve, and the test curve is compared with the reference curve so as to identify a reflection peak which exists in the reference curve but disappears at a corresponding position in the test curve and to determine a branch optical path, where an optical network user terminal corresponding to the reflection peak which disappears is located, as a fault light splitting branch below the PON port; whether a novel reflection peak exists in the test curve but does not exist at a corresponding position in the reference curve is identified; and if the novel reflection peak exists, the position of the novel reflection peak is determined as the position, where a broken fiber fault happens, in the fault light splitting branch. The method and the system can be used for quickly and accurately positioning the fault of the optical fiber behind the optical splitter in the PON.
