Data sending and parsing method and parsing device achieving parsing method

Abstract

The invention discloses a data sending method and a parsing method corresponding to the data sending method in an ODN optical network, and meanwhile discloses a parsing device special for achieving the parsing method. The data sending method and the parsing method include the steps that when data are sent, corresponding relations between MAC addresses of data sending devices in the network and lengths of data packages sent by the data sending devices are built, and the data packages are sent after being integrated again according to the relations; when the data are parsed, the MAC addresses are parsed according to the corresponding relations between high levels of different lengths and the MAC addresses, wherein the corresponding relations are read by the parsing device, so that address information of all ONU devices getting access to the optical network or all OLT devices getting access to the optical network is obtained, and working efficiency is improved substantially. The parsing device only needs to be clamped on an optical fiber in the data obtaining process and can be omitted when the data are not measured, operation is convenient, repeated setting on all ports is not needed, cost is saved, and device investment is reduced.

Description

technical field [0001] The invention belongs to the technical field of optical fiber communication, and in particular relates to a data sending method in an ODN optical network, a corresponding analysis method and an analysis device for realizing the analysis method. Background technique [0002] With the continuous advancement of network construction, optical fiber network has been gradually promoted and applied. A network generally includes a core layer, an aggregation layer, and an access layer. Among them, the most complex and difficult part to manage is the access layer. In the development of FTTx, the access layer needs to build a huge optical fiber distribution network, that is, the ODN network. ODN (Optical Distribution Node) is an optical distribution node, which is an FTTH optical cable network based on PON equipment. Its role is to provide optical transmission channels between OLT and ONU. [0003] The cost of ODN network construction is high. At the same time...

Problems solved by technology

[0004] The currently applied ODN network intelligent management system needs to establish system management software and be equipped with related hardware. These hardwares need to be distributed at each port of the ODN, and real-time online testing is required during management. With the continuous complexity of the network structure, the number of hardware is extremely large, resulting in high cost

People will also use fiber optic line checking instrument to manage the optical fiber network. The fiber optic line checking instrument includes two instruments, one sending and one receiving. Two people must hold one and use it at the same time. One person transmits at the computer room end, and the other person needs to receive at the user end. , the distance between the two locations ranges from hundreds of meters to 20 kilometers, which is not only troublesome to use, but also takes a lot of time and is inefficient during the line checking process
