Description

Technical Field

[0001] The present invention relates to the technical field of optical fiber communication, and particularly relates to a method for inventorying PON port resources based on the TL1 protocol. Background Art

[0002] The PON (Passive Optical Network) network is a passive optical network with a point-to-multipoint structure, which consists of an optical line terminal (OLT), an optical distribution network (ODN), and an optical network unit (ONU). Its downstream uses a broadcast mode, and its upstream uses a time division multiple access mode, which can flexibly form topological structures such as tree-shaped, star-shaped, and bus-shaped, and has the advantages of saving optical cable resources, sharing bandwidth resources, saving computer room investment, fast network construction speed, and low comprehensive network construction cost.

[0003] Optical fiber communication is an important way for the construction of the access layer network. The optical splitter is an important part of the communication network, and the characteristic of the PON network is that the optical modem can work on any port of the optical splitter. However, there is a lack of effective detection means for the maintenance and update of resource data in the PON network. The PON network resources installed at the installation site may not be accurate enough. Therefore, the optical splitter ports actually installed at the installation site may be inconsistent with those recorded in the asset management system. To ensure the accuracy of on-site resources, it is necessary to inventory the port resources connected at the home broadband site to confirm the actual connection situation on site.

[0004] In view of the problems of low efficiency and easy error in manual inventory of end optical splitters, the present invention proposes a method for inventorying PON port resources based on the TL1 protocol. Summary of the Invention

[0012] Step S3: Power on the test ONT and connect the test ONT to an idle port of the optical splitter to obtain the corresponding PON port information of the optical splitter.

[0013] After the PON port test is completed in Step S4, unplug the optical fiber of the test ONT, send a query instruction for the optical network unit (ONU) list, and analyze the instruction result to conduct an inventory check of the information of the subordinate users.

[0014] Step S5: Select the pigtail for printing according to the inventory check result, and paste the label on the corresponding pigtail.

[0015] After all ports of the optical splitter are inventoried in Step S6, submit for correction of the comprehensive resource data.

[0016] In the said Step S3, the test ONT obtains the corresponding PON port information of the optical splitter through an unregistered ONU query instruction.

[0017] In the said Step S3, the underlying implementation is based on the TL1 instruction, and the query instruction for the unregistered ONU is: LST-UNREGONU::OLTID=:CTAG::.
