Embodiment 1
[0063] This embodiment provides a detection method for a client device in a passive optical network system, the passive optical network system includes an OLT, the OLT corresponds to N client devices, and the client device is an ONU or an ONT, wherein , N is a positive integer, the N client devices form a total set, and the OLT stores a feature library containing a plurality of set features, the set features include: the client device frequently interrupts services, the client device Frequent online and offline, all client devices corresponding to the PON port of the OLT cannot register, and the OLT receives a signal loss alarm.
[0064] Set m=0, such as figure 1 As shown, the detection method includes the following steps:
[0065] Step 101, after receiving the feature of the client device, judge whether the feature matches the set feature in the feature library, if the result is a match, it is determined that there is an abnormal client device in the client device, then Ent...
Embodiment 2
[0086] On the basis of Embodiment 1, this embodiment also provides a detection method for a client device in a passive optical network system, such as figure 2 As shown, the detection method includes the following steps:
[0087] Step 201, after receiving the feature that appears on the client device, judge whether the feature matches the set feature in the feature library, if the result is a match, determine that there is a potentially abnormal client device in the client device, Then enter step 202, if the result is a mismatch, it is determined that there is no potential abnormal client device in the client device, and then end the process;
[0088] Step 202, using the binary search method to divide the total set into a first set and a second set, divide the first set into a first subset and a second subset, and divide the second set into a third subset and the fourth subset;
[0089] Step 203: Test the first subset and the second set by the burst clock data recovery meth...

Abstract
The invention provides a passive optical network system and a detection method for customer premise equipment of the passive optical network system. The detection method includes that when the customer premise equipment is abnormal and signal receiving strength is zero, a dichotomizing searching method is used for performing dichotomization on a total set for three times; a first subset and a second set, a second subset and the second set, a third subset and a first set and a fourth subset and the first set are tested through a burst clock and data recovery method, if test results are right, the subsets corresponding to the right test results are eliminated, the rest subsets and sets form the total set, the dichotomizing searching method is used for performing dichotomization and tests on the total set again, if test results are wrong, random sort is performed on all customer premise equipment in the total set through an equal probability random sort algorithm, and the dichotomizing searching method is used for performing dichotomization and tests again until all abnormal customer premise equipment is detected. According to the passive optical network system and the detection method for the customer premise equipment of the passive optical network system, time consumption is reduced, logical complexity is lowered, and the detection method is flexible.
Description
technical field [0001] The present invention relates to a passive optical network system, in particular to a detection method of user end equipment in the passive optical network system and a passive optical network system including the detection method. Background technique [0002] With the continuous maturity of passive optical access network technology and the continuous expansion of passive optical access network scale, operators gradually shift the construction of passive optical access network from function realization and network scale to operation and maintenance. This requires network equipment vendors to provide corresponding technical solutions. [0003] In the operation and maintenance of the passive optical access network, the diagnosis and fault repair of the optical link are very important, especially the fast positioning and isolation of the rogue ONU (optical network unit) is the top priority, because once the optical link appears Faults will affect the se...
