Problems solved by technology

[0005] Although this kind of passive optical network equipment enhances the stability of optical communication to a certain extent, its main path is equipped with a backup path, which will obviously increase the investment cost, and the continuous opening of the backup path will also increase energy consumption. The solution has further R&D room for improvement

Embodiment 1

[0054]A passive optical network communication method for such as figure 1 The passive optical communication network shown, the network includes at least one central office and a plurality of nodes connected to each other in a network topology, figure 1 Take one central office and one node as an example.

[0055] The node OADM is designed, for example, as an optical add-drop multiplexer, but can also be realized with other components, such as an optical cross-connect, optical splitter, etc. The central office CO and the node OADM are connected to each other through a main path and a backup path. The central office CO generates useful optical signals and transmits them to the node OADM through a main path consisting of at least one optical fiber. The main and backup paths can be designed as one-way or two-way lines. The node OADM includes a device for switching between the primary path and the backup path.

[0056] refer to figure 2 The passive optical network communicatio...

Embodiment 2

[0069] A storage medium and a system, storing a computer program for calling by a processing module to implement the passive optical network communication method in Embodiment 1.

Embodiment 3

[0071] A passive optical network communication system, referring to Figure 4 , including a memory 2 and a processor 1, the memory 2 stores an instruction set for the processor 1 to call to realize the following functions:

[0072] Obtain the working status of the working path of the passive optical network, the working status includes whether the working path is running normally;

[0073] When the working path runs abnormally, identify the number information of the abnormal working path;

[0074] And according to the serial number information, determine the grouping information corresponding to the abnormal working path;

[0075] According to the preset group backup relationship, enable the group secondary backup path.

[0076] According to the traffic volume of the passive optical network communication, the communication paths matching the traffic volume are set as secondary backup paths.

[0077] After switching to the secondary backup path, if the instant communication ...

Abstract

The invention discloses a passive optical network communication method, a storage medium and a system, and relates to the optical fiber communication technology, including obtaining the working state of the passive optical network working path; when the working path runs abnormally, identifying the serial number information of the abnormal working path; And according to the serial number information, determine the grouping information corresponding to the abnormal working path; according to the preset grouping backup relationship, enable the grouping secondary backup path. Monitor the working status of the working path of the passive optical network. If the working path is abnormal, identify the number of the abnormal working path, and then determine the grouping information of the working path according to the number information, and enable the secondary backup path of the grouping according to the standby relationship corresponding to the grouping , so as to realize the whole marshalling as a unit, to equip the marshalling with spare communication routes, thereby reducing the number of spare communication routes and saving costs. consumption.

Description

technical field [0001] The present invention relates to optical fiber communication technology, more specifically, it relates to a passive optical network communication method, storage medium and system. Background technique [0002] PON (Passive Optical Network) is a single-fiber bidirectional optical access network using a point-to-multipoint (P2MP) structure. The PON system consists of an optical line terminal (OLT) at the central office, an optical distribution network (ODN) and an optical network unit (ONU) at the user side, and is a single-fiber bidirectional system. As a new generation of broadband access technology, PON has high reliability and low maintenance cost. It can meet current and future broadband service requirements and is widely used. [0003] A passive optical network usually includes at least one backbone, the so-called central office, and a large number of passive optical nodes. These nodes are connected to the central office through optical fibers, ...
