Description
Technical field
The present invention relates to the optical-fiber network technology of the communications field, specifically refer to a kind of methods, devices and systems of realizing the integrated management relay.
Background technology
GPON/EPON (Gigabit-Capable Passive Optical Network/Ethernet PassiveOptical Network) is the comprehensive access technology of new generation broadband passive light, traditional GPON/EPON system is by optical line terminal (OLT, Optical Line Terminal), light distributed network (ODN, OpticalDistribute Network) and optical network unit (ONU, Optical Network Unit) forms, optical line terminal OLT connects one or more ODN for OAN provides network side interface (SNI); The ODN data broadcasting that OLT is descending arrives each ONU, and is same, and ODN arrives OLT with the upstream data of ONU by aggregate transmission.ONU provides user side interface (UNI) for OAN, link to each other with ODN simultaneously, if ONU provides User Port Function simultaneously, provide Ethernet user port or POTS (Plain OldTelephone Service) user port as ONU, then be called ONT, hereinafter if not otherwise specified, the unified ONU that becomes of ONU, ONT.
Passive ODN is by generally being made up of trunk optical fiber, optical splitter and shunt optical fiber, and trunk optical fiber connects OLT and optical splitter, and optical splitter connects ONU by shunt optical fiber.Owing to the influence of factors such as the Output optical power size that is subject to ODN Line Attenuation and existing generating laser, receiver sensitivity, EPON/GPON only supports that maximum ODN fiber lengths is 20Km at present.
To be applied in population rarer diffusing when regional as PON, in order to cut operating costs, then require the ODN of PON system can coverage wider, and the quantity of local side website reduces.The scheme that prior art proposes, as shown in Figure 1, prior art generally increases a repeater (ExtenderBox) and extends optical line terminal to the fiber lengths between optical network unit in existing ODN system, increase the service coverage of optical line terminal place office.This PON system in the industry cycle is called as long distance P ON (LR-PON).Repeater is the interface UNI (User Network Interface) of ANI interface (Acess NetworkInterface) repeater near branch light path device side near the interface of optical line terminal side among the LR-PON.Distance between the optical line terminal repeater can reach 40Km, and the distance between repeater and the optical network unit can reach 20km, promptly introduce repeater after, the coverage of LR-PON can reach 60Km.
OMCI is a kind of configuration transmission channel that defines in the GPON standard, and the OMCI passage is based upon between OLT and the ONU, and ONU is at the OMCI passage of setting up when OLT registers between ONU and the OLT.OMCI is the master-slave mode management agreement, and OLT is a main equipment, and ONU is a slave unit, a plurality of ONU equipment that OLT connects below by OMCI passage control OLT.The various data abstractions of in the OMCI agreement OLT being managed ONU become agreement to manage information bank (being called for short MIB) independently, and the basic information unit (BIU) of management information bank is managed entity (being called for short ME, Managed entity).According to various types of configurations of ONU, OMCI has defined each ME of OLT control ONU.ONU realizes the configuration management function of each ME under the control of OLT.
In order to realize management to Extender Box, guarantee the simplification of intercommunication between OLT and the Extender Box simultaneously, when between OLT and integrated management ONU, a plurality of Extender box being managed, just there is the problem of PON mouth and Extender Box matching relationship how to discern OLT by OMCI.
At the problems referred to above, prior art must be input among network management system and the OLT by the matching relationship of artificial nucleus to OLTPON mouth and Extender Box after network design is finished at every turn by hand.
Above-mentioned prior art has following shortcoming:
(1) because distance distant (the longest 40km that reaches) usually between optical line terminal and the relay, when number of fibers many, when matching relationship was complicated, the manual operation comparison difficulty of getting up was easily because the artificial origin causes matching relationship and network actual disposition not to meet.
