Here, described optical fiber link comprises port and/or the optical branching device port of described OLT to the light jumping fiber between described ONU.In described intelligent ODN management system, record electronic tag that each port is corresponding and the corresponding relation of described each port, therefore described intelligent ODN management system just can record the corresponding relation between a certain electronic tag and its corresponding optical fiber link.And then according to the corresponding relation of described electronic tag and described logic authentication sign, just can record the corresponding relation between described logic authentication sign and described optical fiber link.
If optical fiber link corresponding to 105 described ONU breaks down, described intelligent ODN management system obtains the described logic authentication sign of described ONU.
In described OLT, store the logic authentication sign of all ONU, when the faults such as going offline appears in described ONU, operating personnel just can inquire about the logic authentication that OLT obtains this ONU and identify.Operating personnel are again according to the described intelligent ODN management system of logic authentication sign inquiry obtaining, in fact, when operating personnel inquire about described intelligent ODN management system according to the logic authentication sign obtaining, described intelligent ODN management system has also obtained described logic authentication sign simultaneously.
Described intelligent ODN management system, after the corresponding relation recording between described logic authentication sign and described optical fiber link, also can send to described OLT by described logic authentication sign.After described OLT receives described logic authentication sign, can record described logic authentication and identify and generate an initial password relevant to described logic authentication sign.Like this, then after described logic authentication sign and described initial password are distributed to etc. to ONU to be configured, described ONU just can authenticate and identify and described initial password carry out access authentication according to described logic.
106, in intelligent ODN management system, inquire about the corresponding relation between described logic authentication sign and described optical fiber link, obtain the optical fiber link that described ONU is corresponding.
After obtaining the optical fiber link that described ONU is corresponding, the optical fiber link that operating personnel just can be corresponding according to described ONU, obtains the port from described OLT to process described ONU, and then investigates one by one, location fault.
The invention provides a kind of Fault Locating Method, in intelligence ODN management system, store the logic authentication sign of ONU and the corresponding relation of optical fiber link, when the faults such as going offline appears in described ONU, can obtain optical fiber link corresponding to described ONU by the logic authentication sign of described ONU, in prior art, can only obtain logic corresponding to described ONU authentication sign and but can not determine that the optical fiber link that described ONU is corresponding compares by inquiring about described OLT, method provided by the invention, workmen can inquire about the logic authentication sign of ONU in intelligent ODN management system and the corresponding relation of optical fiber link, obtain the optical fiber link that described ONU is corresponding, and then investigate one by one the port in described optical fiber link, thereby accurately locate fault.
