Detailed Description
The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings.
An optical splitter is a component that constitutes a passive optical network (Passive Optical Network, PON); PON is a passive optical network of a point-to-multipoint structure; the PON is composed of an OLT at the office side, optical network units (Optical Network Unit, ONUs) at the subscriber side, and an optical distribution network (Optical Distribution Network, ODN). Wherein, the ODN is composed of passive devices such as optical splitters.
Optical splitters, also known as optical splitters, are optical fiber splicing devices having multiple inputs and multiple outputs, commonly used for coupling, branching, and distributing optical signals. The optical splitters are connected through optical cables, and the optical cables run in laying sections such as pipelines. The optical splitter is an important device in the wired access network, and a complete cell home broadband network wired access topological graph can be displayed through the device. The connectivity of the optical splitter is the basis for showing the network topology, and the connectivity of the optical splitter and the network topology are checked in the acceptance link of the cell home broadband network engineering, so that the method is an important index for detecting whether the engineering is qualified or not. In the fault investigation link, the pre-investigation of the connectivity of the optical splitter can improve the investigation efficiency. When the household broadband user grows all the time and the whole light splitting ratio needs to be expanded, the topological condition of the light splitter is checked, the capacity of the light splitter is expanded at a proper position, the whole utilization rate of the light splitter can be improved, and the cost is reduced.
At present, the domestic communication operators have less research on efficient solutions of the connectivity of the optical splitter. The connectivity between the splitters is confirmed in situ with a line finder only against a line of service personnel. With the popularization of the home broadband, the home broadband network of the community is complicated, and the investigation efficiency is low by using a line finder. Moreover, the line finder cannot check the topology trend of the residential home broadband network in real time, and when a network line is newly established, the line finder can only determine whether the line is efficiently utilized by the experience of a line operation and maintenance personnel, so that the overall utilization rate of the optical splitter is reduced, and meanwhile, the line finder has certain limitation.

It is to be understood that the examples provided herein are for the purpose of illustration only and are not intended to limit the invention.

Fig. 1 is a flowchart of a method for determining connectivity of an optical splitter according to the present invention, as shown in fig. 1, the flowchart may include:
step 100: acquiring a beam splitter model of each beam splitter in a cell home broadband network; the beam splitter model comprises a beam splitter identifier and a superior device identifier of the beam splitter.
Here, the optical splitter is a passive device in a cell home broadband network, and is composed of an entrance and exit slit, a reflecting mirror and a dispersive element; its function is to distribute downstream data and concentrate upstream data. The optical splitter is provided with an uplink optical interface and a plurality of downlink optical interfaces; the optical signals from the uplink optical interfaces are distributed to all the downlink optical interfaces and transmitted; the optical signals from the downstream optical interface are distributed to the unique upstream optical interface for transmission.
In the embodiment of the invention, each beam splitter in the district home broadband network has a corresponding beam splitting ratio; for example, the splitting ratio of the splitters may be 1:8, 1:16, 1:64, etc.; the light splitting ratios of the different light splitters can be the same or different; the setting can be performed according to the actual application scenario, and the present invention is not limited thereto.
In some embodiments, there are two main ways of splitting the cell home broadband network; primary and secondary light splitting; when a primary light splitting mode is adopted, the light splitter is generally arranged at the light junction box; when the two-stage light splitting mode is adopted, the first-stage light splitter is generally arranged at the light cross box, and the second-stage light splitter is generally arranged at the fiber splitting box or the multimedia box.
In the embodiment of the invention, the optical splitter identifier included in the optical splitter model can be an optical splitter number or other attribute information of the optical splitter; such as the name of the beam splitter, the installation address, the rule model, etc.
Here, the upper device of the optical splitter may be an upper splitter or an OLT. In the case that the upper device of the beam splitter is an upper beam splitter, the upper device identifier may be the number of the upper beam splitter, or the name, the installation address, the rule model number, etc. of the upper beam splitter; in the case where the upper device of the optical splitter is an OLT, the upper device identifier may be an OLT number, or may be the name, the installation address, the rule model number, or the like of the OLT.
In some embodiments, the modeling modes of the optical splitters are not limited to the embodiments of the present invention, and the modeling can be performed by using a unified modeling language (Unified Modeling Language, UML), and other modeling modes can also be used.
In the embodiment of the invention, for establishing the beam splitter model of each beam splitter, the attribute information of each beam splitter needs to be recorded; here, the optical splitter identifier of each optical splitter and the upper equipment identifier of the optical splitter and the box identifier to which the optical splitter belongs may be recorded in the optical splitter model of each optical splitter by a constructor in the construction process of the community home broadband network project.
In some embodiments, the identifier of the optical splitter of each optical splitter, the identifier of the upper-level device of the optical splitter and the identifier of the box body to which the optical splitter belongs may be attached to the surface of the optical splitter or the box body to which the optical splitter belongs in the form of a bar code or a two-dimensional code, and then, the attribute information of each optical splitter may be recorded by scanning the bar code or the two-dimensional code through the device with the scanning function; attribute information of each beam splitter may be recorded in other ways.
It can be seen that by recording the attribute information of each optical splitter to the optical splitter model, the more complete the attribute information contained in the optical splitter model of each optical splitter is, and further, the more accurate the result of determining connectivity between optical splitters according to the optical splitter model is.
Step 101: establishing a topological model of the cell home broadband network according to the beam splitter model of each beam splitter; the topology model represents the connection relation between each optical splitter and the OLT equipment in the cell home broadband network.
The OLT device is a service node-side device in the cell home broadband network, and is connected to the front-end switch through a network cable, and converts the service node-side device into an optical signal, and is interconnected with an optical splitter at the user end by using a single optical fiber.
In the embodiment of the invention, the connection relation between each optical splitter and the OLT equipment is as follows: the OLT equipment is connected with a first-stage optical splitter in the cell home broadband network, the first-stage optical splitter is sequentially connected with a second-stage optical splitter, the second-stage optical splitter is sequentially connected with a third-stage optical splitter, and the like until the connection with the last-stage optical splitter in the cell home broadband network is completed. Here, the connection relation of each optical splitter and the OLT apparatus may represent a topology model of the home broadband network of the cell.
In some embodiments, for a specific implementation of establishing a topology model of a cell home broadband network according to a splitter model of each splitter, the method may include: establishing an array of beam splitter models of all the beam splitters according to the beam splitter models of all the beam splitters; circularly searching the optical splitter identifiers of the lower-level optical splitters of each optical splitter downwards according to the OLT identifiers, and placing the optical splitter identifiers of the lower-level optical splitters of each optical splitter into a corresponding optical splitter model array until the optical splitter identifiers of the optical splitters in the community home broadband network are searched; and establishing a topological model of the cell home broadband network according to the beam splitter model and the beam splitter model array of each beam splitter.
Here, the OLT identifier represents an identifier corresponding to the OLT device in the cell home broadband network; the method comprises the steps that in a cell covered by a cell home broadband network, the OLT equipment corresponding to each optical splitter is the same, so that the OLT identifications corresponding to each optical splitter are the same; the OLT identifier may be a number of the OLT device, a name of the OLT device, an installation address of the OLT device, a rule model of the OLT device, or the like.
In the embodiment of the invention, the construction process of the topology model can be as follows: firstly, writing an OLT identifier into a beam splitter model, putting the beam splitter model into a topology model in a predefined cell home broadband network, initializing a beam splitter model array, and putting the beam splitter model array into the topology model; then searching the optical splitter identifier of the first-stage optical splitter according to the OLT identifier, putting the searched optical splitter identifier of the first-stage optical splitter into an optical splitter model array, initializing an optical splitter model array, searching the optical splitter identifier of the second-stage optical splitter according to the optical splitter identifier of the first-stage optical splitter, putting the searched optical splitter identifier of the first-stage optical splitter into the optical splitter model array, and so on until the optical splitter identifier of the last-stage optical splitter in the cell home broadband network is put into the optical splitter model array; finally, by combining the beam splitter model of each beam splitter with the corresponding beam splitter model array, a topology model of the cell home broadband network can be established.
Here, each beam splitter model corresponds to a beam splitter model array, and is used for storing the beam splitter and the beam splitter identifiers of the lower beam splitters of the beam splitter; therefore, each beam splitter model array can represent the association relation between two stages of beam splitters, and further, by combining the beam splitter model of each beam splitter with the corresponding beam splitter model array, a topology model of the cell home broadband network can be established, and the topology model comprises the network topology structure of each beam splitter of the cell home broadband network.
In some embodiments, the splitter model array of each splitter model also includes an identification of the splitter box, where the splitter box is the box in which the splitter is mounted.
In some embodiments, the box identifier may be a box number to which the optical splitter belongs, or may be a name, an installation address, a rule model number, etc. of the box to which the optical splitter belongs; wherein, the box body can be an optical fiber splitting box, an optical fiber cross box or a multimedia box.
In the embodiment of the invention, the topological model can be enriched through the box body identification of each beam splitter, so that the information of the topological model is more complete, and more reference data can be provided for constructors.
Step 102: determining connectivity of a first optical splitter and a second optical splitter in each optical splitter based on a topological model of the cell home broadband network; the first and second splitters represent two different splitters in the topology model.
In the embodiment of the present invention, as known from step 101, the topology model includes a network topology structure of each optical splitter of the cell home broadband network; namely, the topology model not only covers all the optical splitters in the cell home broadband network, but also defines the connection relation among the optical splitters, and further, the connectivity of the first optical splitter and the second optical splitter in the optical splitters can be determined through the topology model of the cell home broadband network.
Here, the first beam splitter and the second beam splitter may be any two different beam splitters in the topology model; the two optical splitters may be optical splitters of the same stage in the topology model, or optical splitters of different stages in the topology model.
In some embodiments, determining connectivity of the first and second splitters in each splitter based on a topology model of the cellular home broadband network may include: searching for an initial beam splitter of the first beam splitter and the second beam splitter based on a topological model of the cell home broadband network; judging whether the initial beam splitters of the first beam splitter and the second beam splitter are the same or not, and obtaining a judging result; under the condition that the judging result is the same, the first beam splitter is determined to be communicated with the second beam splitter; and if the judging result is different, determining that the first beam splitter and the second beam splitter are not communicated.

In some embodiments, in the case that the beam splitter p and the beam splitter q are not connected, the beam splitter p and the beam splitter q may be further connected according to actual situations; FIG. 2c is a schematic diagram of two optical splitters in communication according to an embodiment of the present invention; as shown in fig. 2c, since the start splitter parent_p of the splitter p is numbered 1; the initial beam splitter parent_q number of the beam splitter q is 8; connecting the initial beam splitter parent_p with the initial beam splitter parent_q in a mode of connecting the small number with the large number; further, the beam splitter p communicates with the beam splitter q. FIG. 2d is a schematic diagram showing connectivity of two splitters in an array manner according to an embodiment of the present invention; it can be seen that after the beam splitter p and the beam splitter q are communicated, the beam splitter p and the beam splitter q correspond to the same initial beam splitter parent_q with the number of 8; the unit () adds the tree where the splitter p is located to the root node of the tree where the splitter q is located (the starting splitter parent_q), that is, the splitter can connect two splitters by modifying one link.
In some embodiments, the initial beam splitter of any two beam splitters may be connected in a manner that the small number is connected to the large number; or, the initial beam splitter of any two beam splitters is communicated in a mode of connecting the large number with the small number.
In addition, on the basis of the step A1, the process of establishing a topology model of the cell home broadband network and displaying network topology data is as follows:
step A3: and establishing a topology model for the cell home broadband network.
In some embodiments, a topology membership model may be first determined from a splitter model; the topology member model comprises a splitter model of each splitter and an OLT identifier; the topology member model also includes the box identity to which each beam splitter belongs. Here, other attribute information of each beam splitter or other information of a box body to which each beam splitter belongs may be added in the process of determining the topology member model according to actual scene requirements; for example, the name, installation address, rule model number, etc. of the beam splitter; the name, installation address, rule model and the like of the box body to which each beam splitter belongs.
In some embodiments, the OLT identity represents an OLT identity of a cell to which each splitter corresponds; each optical splitter identifier can be searched according to the OLT identifier; storing the inquired lower-level equipment identifier into a pre-initialized topology member array; similarly, the lower-level equipment corresponding to the lower-level equipment is processed in the mode; and establishing a topology model of the cell home broadband network according to the topology member model and the topology member array.
