An optical network unit is a fiber access terminal device that provides multiple service interfaces to subscribers, which in FTTH (fiber to The Home) service can be understood as a subscriber optical modem.
Specifically, the method comprises the following steps:
step 101, according to the dimensionalities of the optical splitter and the passive optical network port, converging the state information and the alarm information of a plurality of optical network units to obtain the converging condition of a plurality of optical cable sections; the plurality of optical cable sections comprise a main optical path section between the passive optical network port and the primary optical splitter, a branch optical path section between the primary optical splitter and the secondary optical splitter, and a rubber-insulated wire optical cable section between the secondary optical splitter and the optical network unit.

Specifically, when a broadband fault is encountered, a user can conduct fault reporting through a customer service telephone or a web hall platform, the large data platform analyzes broadband account numbers associated with reporting users through data of associated CMR (Communication Management Record ) of reporting information (contact information, name, identity card and the like) of the user, and takes the broadband account numbers as analysis clustering objects, and then the large data platform analyzes an associated target optical network unit (namely an optical network unit used by the user) of the user and an optical splitter and a passive optical network port connected with the target optical network unit through information of associated resources of the user broadband account numbers and information of a PON network management platform, and further analyzes according to dimensions of the optical splitter and the passive optical network port connected with the target optical network unit, specifically, the PON network management starts a round of the state of the ONU under the same PON port and the same OBD, and records.
And 102, determining fault identification results of the plurality of optical cable sections according to the convergence condition.
In determining the convergence condition of a plurality of optical cable sections, fault analysis can be carried out on each optical cable section according to the convergence condition, so that a fault identification result of each optical cable section is obtained, and further, the optical cable section with faults can be accurately positioned, whether a main optical path or a branch optical path or a rubber-insulated-wire optical cable section is obtained.
In an embodiment of the present invention, the determining, according to the convergence, a failure recognition result of the plurality of optical cable segments includes: and indicating that all the optical network units under the passive optical network port are offline under the convergence condition, and judging that a main optical path section between the passive optical network port and the primary optical splitter has faults when the number of the optical network units with signal loss alarms under the passive optical network port is larger than a first threshold value.
The main light section is judged as follows:
for a certain passive optical network port, when information is gathered and known, all optical network units under the passive optical network port are offline, and the number of the optical network units for acquiring signal loss alarms under the passive optical network port is larger than a first threshold, if the first threshold can be 4, that is, the first threshold represents that all the optical network units under a main optical path section are abnormal, then the main optical path section between the passive optical network port and the first-stage optical splitter can be judged to have faults.
As shown in fig. 2b, by opening the resolving job, the PON is obtained with no light alarm, and by judging the usage status of the associated OLT apparatus (0: normal usage; 1, not checking) and then judging whether the PON port has an unrecovered fault, if the PON port has an unrecovered fault, merging an alarm to the generated PON fault (time is configurable), discarding if other conditions exist, not performing fault judgment, if no unrecovered fault, checking the state of the ONU connected to the alarm PON port in real time through TL1, judging whether TL1 is successful in checking, if not successful in checking, generating a PON no-light receiving fault, if successful in checking, judging whether the number of on-line ONUs is equal to 0, discarding if the number of on-line ONUs is not equal to 0, not performing fault judgment, if the number of on-line ONUs is equal to 0, acquiring an ONU list (10 minutes before and after the alarm time) in which the alarm occurs at the same time, if the number of on-line ONUs is equal to 0, discarding if the number of on-line ONUs is not equal to 1, discarding if the number of on-line ONUs is not equal to 0, discarding if the number of POWER OFF ONUs is not equal to 0, and determining whether the number of on-OFF-line ONUs is equal to 5, namely, and whether the number of on-OFF-line ONU is equal to 5, or not equal to 5, and whether the number of on-OFF-state is equal to 5, and lower than one-level ONU is equal to one-level, and lower than one-level ONU is generated in the same optical path, and if the number is not equal to 5, and if the number of on the number of the OFF ONU has a white-OFF has a value and a value is not equal to one level and a value, and generating a main light path breaking fault.
In an embodiment of the present invention, the determining, according to the convergence, a failure recognition result of the plurality of optical cable segments includes: and indicating that at least one optical network unit is on-line under the passive optical network port under the convergence condition, determining that a branch optical path segment between the primary optical splitter and the secondary optical splitter has faults when all the optical network units under the secondary optical splitter are off-line and the number of the optical network units with signal loss alarms under the secondary optical splitter is larger than a second threshold value.
In the case where there is at least one optical network unit online under the passive optical network port, it is possible that the branch optical path segment and/or the rubber-insulated optical cable segment fail if the main optical path segment is characterized as not failed.
The determination of the failure of the branch light segment is as follows:
for a certain secondary optical splitter, information is gathered to obtain that all optical network units under the secondary optical splitter are offline, and the number of optical network units with signal loss alarms under the secondary optical splitter is larger than a second threshold, if the second threshold is 1, that is, all optical network units under the secondary optical splitter are abnormal, it can be determined that a fault occurs in a branch optical path section between the primary optical splitter and the secondary optical splitter.
As shown in fig. 2c, by reading an ONU offline alarm and determining whether the ONU exists in the associated resource, if the ONU exists in the associated resource, the local resource is queried to obtain ONU upstream OBD information, then whether an unrepaired optical path fault (primary or secondary) exists in the optical path in which the ONU exists or not is determined, if the unrepaired optical path fault exists, the alarm is converged under the fault, if the unrepaired optical path fault does not exist, the real-time TL1 queries the ONU state under the PON in which the ONU exists, and determines whether the alarm ONS are LOS, if the alarm ONS are not LOS, the alarm ONU state is determined to be a POWER OFF fault flow, if the alarm ONU state is determined to be a POWER OFF fault flow, then the MDU is determined to be a POWER OFF fault flow, if the alarm ONUs is a LOS, then the number of the POWER OFF is determined to be 0, whether the valid LOS ONU >1 is determined, whether all valid s ONUs are under the secondary d, whether the alarm ONU is determined to be in the PON, whether the number of white OFF is determined to be on the white OFF, and the number is determined to be a white-OFF (the number) and the number is determined to be a white-OFF fault and a number is determined to be able to be generated in the white-OFF condition by the ONU and a fault is configured on the number (on a fault).
In an embodiment of the present invention, the determining, according to the convergence, a failure recognition result of the plurality of optical cable segments includes: and indicating that at least one optical network unit is on-line under the passive optical network port, and at least one optical network unit is on-line under the secondary optical splitter or an optical network unit with no signal loss alarm is not on-line under the secondary optical splitter under the convergence condition, and judging that a rubber-insulated-wire optical cable section between the secondary optical splitter and the optical network unit which is off-line has faults.
In the case where there is at least one optical network unit online under the passive optical network port, it is possible that the branch optical path segment and/or the rubber-insulated optical cable segment fail if the main optical path segment is characterized as not failed.
The fault of the rubber-insulated-wire cable section is judged as follows:
for a certain secondary optical splitter, information is gathered to obtain that at least one optical network unit exists in the secondary optical splitter on-line (i.e. not all the optical network units are off-line), or an optical network unit with no signal loss alarm exists under the secondary optical splitter, namely, the fact that part of the optical network units exist under the secondary optical splitter is normal is represented, and then faults of a rubber-insulated wire optical cable section between the secondary optical splitter and the optical network unit which is off-line can be judged.
In an embodiment of the present invention, further includes: and acquiring state information of the target optical network unit according to a preset time interval, and judging that the fault processing request is processed when the target optical network unit is on line.
For the fault processing request reported by the user, the fault tracking processing is needed, the state information of the target optical network unit is acquired according to a preset time interval (such as 30 minutes), and when the target optical network unit is on line, the fault processing request is judged to be processed, namely the fault is recovered, so that the fault state can be released, and the fault tracking is released.
In an embodiment of the present invention, further includes: a job ticket task is generated for the failed cable segment.
For judging the optical cable section with faults, a work order task can be generated, and an engineer is allocated to the work order task to repair the optical cable section with faults.
In an embodiment of the present invention, further includes: and optimizing the work order task belonging to the same optical cable section fault.
When a plurality of work order tasks (work order tasks generated by reporting by a user) exist, as the faults processed by the plurality of work order tasks may be the same optical cable section faults, the optimization operations such as merging, interception and the like can be performed on the work order tasks belonging to the same optical cable section faults, the dispatching of the plurality of work order tasks with the same faults is avoided, the dispatching quantity of the user-level network work order is reduced, and the fault work order quantity is compressed.
Taking an ODN fault repairing obstacle as an example, the access network manager collects ONU alarm state information in a full quantity, judges and analyzes according to POWER OFF/LOS alarm information of the ONU, associates and gathers analysis (the information of optical cable sections on a PON port-a primary beam splitter and a primary beam splitter of an associated resource system is gathered) from bottom to top, gathers the information of the optical cable sections on the primary beam splitter-the secondary beam splitter to the secondary OBD and the PON port based on the ONU alarm of a user, sequentially generates rubber-insulated wire faults, branch optical path faults and main optical cable faults, and merges and optimizes dispatching orders based on the alarm on the optical cable sections.
In an example, aiming at the problem that the POWER OFF alarm cannot be actively reported due to the performance degradation of part of old optical cats of ONUs, the accurate fault judgment is not possible, the algorithm is optimized, the threshold value of the number of the power_OFF/LOS alarms of the ONUs under the same PON port/second-level OBD is set, and the rejection processing is carried out on the PON port receiving no light/ONU offline alarm caused by the POWER OFF alarm of not less than 80%.
