Abstract
The invention discloses a PON (passive optical network) maintenance method and relates to the technical field of network operation and maintenance. The PON maintenance method is characterized by including determining system composition, system software structures, equipment working environments, technical properties of equipment and problematic circuits, detecting by automatic monitoring, and analyzing situations. The PON maintenance method is reasonable and convenient to operate and implement.
Description
Technical field:
The present invention relates to the network operation and maintenance technology field, be specifically related to the method for the maintenance of PON.
Background technology:
PON is that passive optical-fiber network (Passive optical network) is also known as passive fiber network, for the one of Networks of Fiber Communications, its characteristic is just can settling signal process without power supply, just as the mirror of family, do not need electricity just energy reflected image, except terminal equipment needs to use except electricity, the node in the middle of it is then formed with the fiber optic component that exquisiteness is small and exquisite.Telecommunication network route can rough segmentation be core network (Core Network) and access network (Access Network) two part.
PON system structure primarily of central office optical line terminal (OLT), comprise the optical distribution network (ODN) of Passive Optical Components, the network unit/optical network terminal (ONU/ONT of user side, it is distinguished as ONT and is located immediately at user side, and between ONU and user, also have other network, as Ethernet) and Element management system (EMS) composition, usually adopt point-to-multipoint tree topology.At down direction, the multiple business such as IP data, voice, video, by the OLT being positioned at central office, are adopted broadcast mode, are assigned to all ONU unit on PON by the 1:N passive optical splitter in ODN.At up direction, the multiple business information from each ONU is coupled to same optical fiber by the 1:N passive light mixer in ODN without interfering with each other, finally delivers to and is positioned at local side OLT receiving terminal, be similar to the structure of point-to-point.
Summary of the invention:
Technical problem to be solved by this invention is that overcoming existing technological deficiency provides a kind of method that method is reasonable, easy to operate, implement the maintenance of PON easily.
Technical problem to be solved by this invention adopts following technical scheme to realize:
The method of the maintenance of PON, is characterized in that: comprise the following steps,
The composition of step one, certainty annuity: the external OTDR of native system is OTDR+ optical switch+wave multiplexer+reflective optical system;
The structure of step 2, certainty annuity software: GPS location+map interface+alarm and driven management, namely orients particular location by GPS, by third party's map, and display current detection area condition in real time, webmaster page prompts warning information, display working condition;
Step 3, determine the operational environment of equipment: ambient temperature :+5 DEG C ~+35 DEG C, relative humidity: be not more than 90% when+5 DEG C, supply voltage :-48V ± 20% direct current, plus earth, 220V exchange (must configuration UPS), system MTBF: >=100000 hours;
Step 4, determine that Technical properties of plant indicates: install: 19 inch standard frames, bracket height unified for 2000mm, communication interface: RS232 or RS422/485, monitor fault after, be limited to during warning 3min, from the moment that monitored optical fiber breaks down to failure response time when accepting alarm and show this alarm time be limited to 1 minute (not containing signal transmission time), the mean free error time of fiber-optic monitoring equipment is greater than 10 years, recovery time of non-self fault: after failture evacuation, native system can recover normal operation in 3 minutes;
Step 5, problem identificatioin circuit: according to the complaint of user, send someone user place, to check the Fiber connection of ONU, then need to disconnect the Fiber connection at optical splitter place, then use OTDR meter check optical fiber;
Step 6, to detect by automatically monitoring: the fiber connection status of optical of monitoring each FTTX user, test data gathers, and compares with reference data in database;
Step 7, analysis situation: the degradation trend of accurate analysis optical cable and failure condition, automatically according to alarm triggered relevant treatment flow process, or provide SMS notification related personnel to process.
Beneficial effect of the present invention is: the inventive method is reasonable, easy to operate, it is convenient to implement.
Accompanying drawing illustrates:
Fig. 1 is the external OTDR block diagram of system of the present invention.
Fig. 2 is software configuration composition diagram of the present invention.
Embodiment:
