Description

Optical network resource management method, server and optical network system

This application requests the priority of the Chinese patent application submitted to the State Intellectual Property Office of China on July 22, 2022, with the application number 202210873465.2 and the application name "Optical Network Resource Management Method, Server and Optical Network System", and its entire content has been approved This reference is incorporated into this application.

Technical field

The present application relates to the field of optical communication technology, and in particular to an optical network resource management method, a server and an optical network system to which the optical network resource management method is applied.

Background technique

With the development of optical communication technology, Passive Optical Network (PON) technology is widely used in access networks. Fiber To The Home (FTTH) is a method of access network. It not only provides greater communication bandwidth, but also relaxes the requirements for environment and power supply, reduces construction costs, and simplifies maintenance requirements.

FTTH mainly uses PON technology, with dozens or hundreds of optical network units (Optical Network Terminal, ONT) sharing an optical line terminal (Optical Line Terminal, OLT). Common PON networking includes two types: equal-ratio optical fiber and unequal-ratio optical fiber. The unequal-ratio optical fiber scenario includes multi-level cascaded optical fiber boxes connected to the trunk cables. Each optical fiber box outputs a portion of the optical power (for example, 70%) to the next level along the trunk cable, and outputs the other portion of the optical power (for example, 30%) to the user terminal. This unequal splitting method causes differences in the power of the entrance ports of different levels. The power of the entrance ports of the front series is larger, and the power of the entrance ports of the back series is smaller. This also brings about the problem of the entrance port optical power. The problem of uneven power distribution. Moreover, the optical power loss in the later stages is greater, which limits the number of total users and the longest coverage distance available during network planning.

In order to solve the problem of uneven optical power distribution of the entrance ports of different levels, the optical fiber boxes of the earlier levels can be set to have a larger splitting ratio (for example, 90:10), and the optical fiber boxes of the later levels can have a larger splitting ratio. Small (e.g. 60:40). However, this method requires multiple types of fiber optic boxes for networking. However, the appearance differences between various types of fiber optic boxes are small. It is easy to install the fiber optic box incorrectly when installing the fiber optic box. It is also easy to connect the wrong port when connecting the fiber optic cable to the fiber optic box. Moreover, the installation error of the fiber optic box and the port connection error are difficult to maintain in the future. Verification and positioning are performed during the process.

The embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

Embodiment 1

This embodiment provides an optical network system. Referring to FIG. 1 , the optical network system 1 of this embodiment includes multiple ODN devices 11 and multiple optical cables 12 . Multiple ODN devices 11 are cascaded, that is, multiple ODN devices 11 are connected in sequence to form a multi-level structure. At least one optical cable 12 is connected between each two adjacent levels of ODN devices 11, and the two ends of each optical cable 12 are connected respectively. Different ODN devices11. The optical network system 1 also includes an optical line terminal (Optical Line Terminal, OLT) device 13. The OLT device 13 is connected before the first-level ODN device 11 and is used to output optical signals. The optical network system 1 distributes optical signals in a preset manner through the ODN equipment 11 and the optical cable 12 .

Please refer to Figure 1 and Figure 2 together. In this embodiment, each ODN device 11 has a device identification 111. Each ODN device 11 includes a plurality of connection ports 112 and a plurality of optical channels 113 corresponding to the connection ports 112 one-to-one. Each connection port 112 has a port identifier 114 . Each optical channel 113 is used to transmit optical signals. The optical signals transmitted in each optical channel 113 have different functions (such as for optical communication, optical sensing, etc.), or the optical signals transmitted in each optical channel 113 are used. Distribution with different splitting ratios.

Each optical cable 12 is connected to one of the connection ports 112 , and each optical cable 12 has an optical cable identification 121 . The optical cable 12 is used to transmit optical signals, and is also used to transmit the optical signals to the corresponding optical channel 113 through the connection port 112 .

The equipment identification 111, the port identification 114 and the optical cable identification 121 are used to determine whether the ODN equipment 11 and the optical cable 12 are connected correctly. When the optical cable 12 and the connection port 112 of the ODN equipment 11 are connected correctly, the corresponding equipment identification 111, port identification 114 and optical cable There is a unique matching relationship between the identifiers 121. That is, based on the correspondence between the device identifier 111, the port identifier 114 and the optical cable identifier 121, it can be determined whether the optical cable 12 is connected to the correct connection port 112 on the correct ODN device 11. The above-mentioned device identification 111, port identification 114 and optical cable identification 121 include, but are not limited to, one-dimensional codes, two-dimensional codes, color codes and other readable graphic codes.

The ODN equipment 11 includes at least one of the following equipment: optical fiber splitting box (Fiber Access Terminal, FAT), optical cable splicing box (Splitting and Splicing Closure, SSC), optical fiber terminal box (Access Terminal Box, ATB), or optical distribution box. Optical Distribution Frame (ODF). Among them, the optical distribution frame is used, for example, for the termination and distribution of central office trunk optical cables in optical fiber communication systems, which can easily realize the connection, distribution and scheduling of optical fiber lines. Optical fiber distribution boxes can be used at user access points in optical access networks to realize the connection between distribution optical cables and home optical cables, optical fiber pass-through, branching and protection functions, and optical splitters can be installed inside. The optical cable connector box can be an outdoor product that supports man/hand hole installation. It is mainly used in user access points of optical access networks to realize functions such as splicing and branching of optical cables and the introduction of user-end optical cables into the home. The optical fiber terminal box is a passive device used to connect the home optical cable and the indoor optical network terminal (Optical Network Terminal, ONT). It can be installed on the user's inner wall to provide optical fiber sockets for the indoor ONT. In this application, the ODN device 11 is not limited to the above types.

Please continue to refer to Figures 1 and 2. In this embodiment, the optical network system 1 is a level 4 system and the ODN device 11 is an ATB for illustration. That is, the optical network system 1 of this embodiment includes four levels of ODN equipment 11, and the ODN equipment 11 of each level is connected in sequence. In this embodiment, the structures of the ODN equipment 11 at the first to third levels are basically the same, and the structure of the ODN equipment 11 at the fourth level is different from the structures of the ODN equipment 11 at the previous three levels. The structures of the ODN devices 11 described in this embodiment are the same or different, mainly referring to the structures of the optical channels 113 in the ODN devices 11 being the same or different.

In this embodiment, the first-level to third-level ODN equipment 11 respectively include four connection ports 112 and two optical channels 113. The four connection ports include two input ports A and B and two output ports A' and B'. Input port A corresponds to output port A', and input port B corresponds to output port B'. The two optical channels 113 correspond to the two input ports A and B one by one. That is, the optical signal input from input port A will be output from output port A' through one of the optical channels, and the optical signal input from input port B will be output from output port A' through one of the optical channels. The optical signal will be output from output port B' through another optical channel.

In the ODN equipment 11 of the first to third levels, different optical channels 113 have different splitting ratios when transmitting optical signals. Each light channel 113 includes a backbone light path 115 and multiple entry paths 116 . The backbone optical path 115 is used to transmit optical signals to the next-level ODN equipment 11, and each entry path 116 is used to transmit optical signals to indoor ONTs. In this embodiment, the light splitting ratio of the optical channel 113 connecting the input port A and the output port A' is 7:3. That is, after the optical signal is input from input port A, 70% of the optical signal continues to be transmitted along the trunk path 115 to the next-level ODN device 11, and 30% of the optical signal will be transmitted along each entry path 116. Distributed to multiple ONTs (eight in this embodiment, the optical signal on each home path 116 is one-eighth of 20%). Similarly, the light splitting ratio of the optical channel 113 connecting the input port B and the output port B' is 8:2.

Please refer to Figure 3. In this embodiment, the fourth-level ODN device 11 serves as the last-level ODN device 11 in the optical network system 1, and its output optical signals will be distributed to the home OTN without being transmitted to the next level. ODN device 11. Therefore, the ODN equipment 11 of the fourth level only includes one input port C for connecting the optical cable 12, and the optical signal input from the input port C is evenly distributed to the eight entrance paths 116 for transmission to the eight entrance OTNs.

Since the optical signal will continue to be lost during the transmission process (which may be caused by the transmission optical cable, the interface between the equipment, etc., and also includes the loss caused by the optical signal entering the home), the optical signal acquired by the ODN equipment 11 in the later stages The energy is lower than that of the ODN equipment 11 in the front stage. Therefore, in the optical network system 1, the optical cable 12 connecting the ODN equipment 11 in the front stage needs to be connected to the input port A, and the optical cable 12 connecting the ODN equipment 11 in the back stage needs to be connected to the input port A. The optical cable 12 needs to be connected to the input port B, so that the backbone path 115 in the ODN equipment 11 at the rear level can obtain a higher proportion of optical signals to make up for the loss when the optical signal is transmitted to the ODN equipment 11 at the rear level. Balance the energy of optical signals obtained by ONTs at all levels.

In this embodiment, the input port A of the first and second level ODN equipment 11 is used to connect the optical cable 12 , and the input port B of the third level ODN equipment 11 is used to connect the optical cable 12 .

It can be seen from this that the connection ports 113 used to connect the optical cables 12 of the ODN equipment 11 at each level are not exactly the same. That is, in the optical network system 1, the connection methods between each ODN device 11 and each optical cable 12 are diverse. This causes the ODN equipment 11 and the optical cable 12 to be easily connected incorrectly, and in the process of maintaining the optical network system 1 , it is difficult to locate the incorrectly connected ODN equipment 11 and the optical cable 12 .

This embodiment also provides a server and an optical network resource management method applied to the server, which is used to cooperate with the aforementioned device identification 111, port identification 114 and optical cable identification 121 to solve the problem of ODN equipment that may exist in the above-mentioned optical network system 1. 11 and optical cable 12 are easily connected incorrectly and difficult to verify and locate during maintenance.

The optical network resource management method of this embodiment is used to verify whether the OND device 11 and the optical cable 12 are connected correctly after the connection between the ODN device 11 and the optical cable 12 is completed.

Please refer to Figure 4. The optical network resource management method in this embodiment includes:

Step S11, obtain a first image, which includes the device identification of the OND device, the port identification of the connection port of the ODN device, and the optical cable identification of the optical cable; and

Step S12: Based on the information in the first image and the preset networking database, determine whether the connection port of the optical cable and the ODN device is correctly connected.

Please refer to Figure 5. In this embodiment, the server 2 can communicate with the terminal device 3 through a wireless network or a wired network to implement the above optical network resource management method.

In this embodiment, the terminal device 3 may be a smartphone, a wearable device (such as smart glasses, a smart watch), or other device with a camera function. The terminal device 3 is used to obtain pictures or images of the ODN device 11 and the optical cable 12, that is, the first image in step S11. The method of obtaining the first image is, for example, shooting, scanning, etc. In this embodiment, shooting is taken as an example for illustration. The pictures or images taken by the terminal device 3 include the device identification 111 and connection port on the ODN device 11 An image of the port identification 114 of the optical fiber cable 112 and the optical cable identification 121 of the optical fiber cable 12 . In this embodiment, the first image is a picture.

After the terminal device 3 captures the above-mentioned first image, it uploads the first image to the server 2 . After acquiring the first image from the terminal device 3, the server 2 identifies the device identifier 111, the port identifier 114 and the optical cable identifier 121 in the first image to obtain corresponding information from the device identifier 111, the port identifier 114 and the optical cable identifier 121. . In other embodiments of the present application, the device identification 111, the port identification 114 and the optical cable identification 121 in the first image can also be identified through the terminal device 3.

In step S11 of this embodiment, the device identification 111, the port identification 114 and the optical cable identification 121 in the first image are identifications on the ODN device 11 and the optical cable 12 that have been connected to each other. The terminal device 3 is used to take pictures of the connection between the ODN equipment 11 and the optical cable 12 connected to each other, so that the first image taken can include the optical cable identification 121 of the optical cable 12, the equipment identification 111 of the ODN equipment 11 connected to the optical cable 12, and the port identification 114 of the input port (A or B) to which the optical cable 12 is connected.

In this embodiment, the device identifier 111 carries the device ID of the ODN device 11, the optical cable identifier 121 carries the optical cable ID of the optical cable 12, and the port identifier 114 carries the port ID.

In step S12, the server 2 will identify the device identifier 111, the port identifier 114 and the optical cable identifier 121 in the first image to obtain relevant information, and compare it with the information in a preset networking database to determine whether the ODN device 11 is Is the optical cable 12 connected correctly?

Please continue to refer to Figure 5. In this embodiment, step S12 includes:

Step S121, determine the level of the ODN device according to the information in the first image;

Step S122: Obtain the preset connection information of the connection port of the optical cable and the ODN device from the preset networking database according to the level;

Step S123: Determine whether the actual connection information of the connection port between the optical cable and the ODN device matches the preset connection information.

When laying the optical network system 1, the construction workers usually install the ODN equipment 11 and the optical cable 12 step by step starting from the first-level ODN equipment 11. Whenever the construction worker completes the connection between the first-level ODN equipment 11 and the optical cable 12, the actual connection information of the ODN equipment 11 and the optical cable 12 will be stored in the actual networking database. The actual connection information includes the connection port 112 on the ODN equipment 11 and the optical cable. The corresponding connection relationship of 12.

In this embodiment, for the first-level ODN device 11, its related actual connection information can be shown in Table 1 below.

Table I

That is, Table 1 shows that the input port A of the first-level ODN equipment 11 is connected to the optical cable 12 with the optical cable ID "Fiber 1", the output port A' is connected to the optical cable 12 with the optical cable ID "Fiber 2", and the input port B and output port B' are not connected to the optical cable 12.

In this embodiment, two optical cable marks 121 are formed on each optical cable 12 . Each optical cable 12 has two ends, and two optical cable identifiers 121 are respectively located at both ends of the optical cable 12 . Cable identifiers 121 on both ends of the same optical cable 12 carry the same cable ID. When installing the optical network system 1, ODN devices 11 located at different levels may be far apart. One end of the optical cable 12 is often connected to the output port (A’ or B’) of the upper-level ODN equipment 11, and the other end is connected to the input port (A or B) of the current-level ODN equipment 11.

In step S121, by identifying the optical cable identification 121 in the first image, the optical cable identification 121 at one end of the optical cable 12 can be traced back to the ODN equipment 11 connected to the other end of the optical cable 12, thereby determining the ODN equipment currently to be installed. 11 series.

For example, in step S121, the server 2 obtains the optical cable ID of the optical cable 12 as "Fiber 2" based on the optical cable identification 121 in the current first image. The server 2 can find the optical cable ID as "Fiber 2" in the actual networking database. The other end of the optical cable 12 is connected to the output end A' of the first-level ODN equipment 11. In this way, it can be determined that the currently connected ODN equipment 11 is at the second level, that is, the level number of the current ODN equipment 11 can be obtained as 2. .

In this embodiment, the server 2 also stores a preset networking database. The preset networking database includes preset connection information. In this embodiment, the preset connection information includes the preset connection methods of the ODN equipment 11 at each level and the optical cable 12 . That is, the preset connection information includes the preset corresponding connection relationship between each connection port 112 and the optical cable 12 on the ODN equipment 11 at each level.

Before the optical network system 1 is laid, a networking model will be pre-planned based on the application scenarios of the optical network system 1. The networking model includes how many levels of ODN equipment 11 the optical network system 1 has, what structure each ODN equipment 11 will use, Information such as how the ODN equipment 11 at each level is connected to the optical cable 12. The default networking database stored in the server 2 includes the default connection information of the ODN device 11 and the optical cable 12 stored according to the above networking model.

For example, in this embodiment, for the second-level ODN device 11, in the networking model, the second-level ODN device 11 uses an ATB with two optical channels 113. The second-level ODN device 11 has two input ports A, B and There are two output ports A' and B'. One optical cable 12 is connected to the input port A of the second-level ODN equipment 11, and the other optical cable 12 is connected to the output port A' of the second-level ODN equipment 11.

According to this networking model, the default networking data of server 2 will store the following default connection information for the second-level ODN device 11:

Table II

This application does not limit the specific expression method of the preset connection information, and it can indicate the correct connection method between the ODN device 11 and the optical cable 12 .

In step S122 of this embodiment, the server 2 obtains that the current level of the ODN device 11 is 2, and can search in the default networking database which connection port 112 of the ODN device 11 with level 2 is used to connect the optical cable, thereby Obtain the default connection information related to the ODN device 11 with level 2.

After the server 2 obtains the first image, it will identify the port identification 114, the optical cable identification 121 and the equipment identification 111 in the first image, and establish the corresponding relationship between the port identification 114, the optical cable identification 121 and the equipment identification 111, thereby obtaining Actual connection information between the ODN device 11 and the optical cable 12.

In step S123, the server 2 compares the obtained actual connection information with the preset connection information in the preset networking database to determine whether the ODN device 11 and the optical cable are connected correctly. For example, in the default networking database, the default connection data stores the input port A of the ODN equipment 11 with level 2 connected to the optical cable 12, while the actual connection information is the input port B of the ODN equipment 11 with level 2. When the optical cable 12 is connected, the server 2 determines that the connection between the ODN device 11 and the optical cable 12 is incorrect. If the actual connection information indicates that the input port A of the ODN device 11 with level 2 is indeed connected to the optical cable 12, then the server 2 determines that the ODN device 11 and the optical cable 12 are connected correctly.

Please continue to refer to Figure 5. The optical network resource management method of this embodiment, if it is determined that the optical cable 12 and the connection port 112 of the ODN device 11 are correctly connected, also includes step S13 of storing the actual connection information.

If the server 2 determines in step S123 that the optical cable 12 and the ODN device 11 are connected correctly, step S13 will be executed. At this time, the actual connection mode of the ODN equipment 11 and the optical cable is stored in the actual networking database. On the one hand, this is beneficial to locating each ODN equipment 11 and the optical cable 12 during the subsequent maintenance of the optical network system 1. On the other hand, the actual networking database It can be used to search for the upper-level ODN equipment 11 corresponding to the leveling of the optical cable 12 when connecting the next-level ODN equipment 11 and the optical cable 12 .

Please refer to Figure 6. The optical network resource management method of this embodiment, if it is determined that the connection between the optical cable 12 and the connection port 112 of the ODN device 11 is incorrect, also includes:

Step S14: Generate first prompt information according to the preset networking database, where the first prompt information is used to indicate the preset connection mode of the connection port between the optical cable and the ODN device.

Step S15: Send the first prompt information to the terminal device.

If the server 2 determines in step S123 that the connection between the optical cable 12 and the ODN device 11 is incorrect, it will execute steps S14 and S15 to generate the first prompt information and send the first prompt information to the terminal device 3 . The terminal device 3 is used to display the first prompt information to the on-site construction workers.

The first prompt information may be text, prompting the construction worker to connect the optical cable 12 to the corresponding connection port 112 of the ODN device 11 . For example, terminal device 3 outputs text: Connect Fiber 2 to input port A of the second-level ODN device 11. The first prompt information may also be a picture. For example, the terminal device 3 displays a schematic diagram of the second-level ODN device 11, and warns the incorrectly connected connection port 112 with a red box, and indicates the correctly connected connection port 112 with a green arrow. The first prompt information may also be voice, for example, the terminal device 3 directly broadcasts how to connect the ODN device 11 and the optical cable 12 . The construction worker can reconnect the optical cable 12 with the ODN device 11 according to the first prompt information displayed on the terminal device 3 .

Referring to FIG. 7 , in a modified embodiment, the server 2 can directly obtain the level of the currently connected ODN device 11 through the location information of the ODN device 11 . In this modified embodiment, the default networking database also stores location information of each level of ODN equipment 11. In this embodiment, the location information includes, for example, the longitude and latitude of the ODN equipment 11. In this embodiment, after the construction worker arrives at the construction site, he can perform positioning through the terminal device 3 and obtain the current location information. The terminal device 3 sends the obtained current location information to the server 2 .

In this modified embodiment, step S121 is: determining the level of the ODN device according to the location information. That is, the server 2 compares the received current location information with the location information of each level of ODN equipment 11 in the preset networking database, and determines which level of ODN equipment 11 the current location information matches. The level of the ODN device 11 at the current location.

Since there may be a certain error when the terminal device 3 is positioned, in this embodiment, "matching" includes that the position information is the same, or the position information is within a certain error range. For example, when the location information is longitude and latitude, the location information can be considered to match each other within a preset range of the longitude and latitude.

In this modified embodiment, if it is determined that the ODN device 11 and the optical cable 12 are connected correctly, the actual connection information of the ODN device 11 and the optical cable 12 and the location information of the ODN device 11 are stored.

As can be seen from the above optical network resource management method, in this embodiment, after the construction worker connects the ODN equipment 11 and the optical cable 12, the first image of the connected ODN equipment 11 and the optical cable 12 can be taken through the terminal device 3, where the first The image includes the device identifier 111 of the ODN device 11, the optical cable identifier 121 of the optical cable 12, and the port identifier 114 of the connection port 112 of the ODN device 11. The server 2 obtains the above-mentioned first image from the terminal device 3, and can obtain the above first image according to the device identifier 111, The optical cable identification 121 and the port identification 114 establish the connection relationship between the ODN equipment 11 and the optical cable 12 (that is, which connection port 111 of the ODN equipment 11 the optical cable 12 is specifically connected to), and obtain the actual connection information between the ODN equipment 11 and the optical cable 12, in which the server 2 A preset networking database is also stored. The preset networking database includes preset connection information of pre-planned ODN equipment and optical cables. Server 2 is used to compare whether the actual connection information is the same as the preset connection information. If not, , then it is determined that the ODN equipment 11 and the optical cable 12 are connected incorrectly at this time. If they are the same, it is determined that the ODN equipment 11 and the optical cable 12 are connected correctly at this time. When the server 2 determines that the ODN device 11 and the optical cable 12 are connected correctly, the actual connection obtained at this time is stored. information in order to subsequently locate each ODN device 11 and each optical cable 12 in the optical network system 1 . When the server 2 determines that the connection between the ODN equipment 11 and the optical cable is incorrect, it will generate a first prompt message and send it to the terminal equipment 3 to display to the construction worker, instructing the construction worker on the correct connection method, which will help avoid the connection between the ODN equipment 11 and the optical cable 12 mistake.

The two optical cable identifications 121 carry the same optical cable ID, and both ends of the optical cable 12 are connected to an ODN device 11. Therefore, the optical cable identification 121 at one end of the optical cable 12 can be associated with the optical cable identification 121 at the other end, and according to the level of the ODN equipment 11 connected to the optical cable identification 121 at the other end, the ODN equipment 11 at this time can be determined. series.

In this embodiment, the second prompt information may be text, picture, voice, etc. For details, please refer to the first prompt information in Embodiment 1, which will not be described again.

After the construction worker connects the optical cable 12 and the ODN equipment 11 according to the aforementioned second prompt information, the first image is captured through the terminal device 3.

Connection error situation. Moreover, by acquiring the first image, the actual connection information of the ODN device 11 and the optical cable 12 can be acquired and stored, which is beneficial to subsequent positioning of the ODN device 11 and the optical cable 12 during the maintenance of the optical network system 1 .

During the construction process, if the ODN equipment 11 and the optical cable 12 are connected incorrectly, the optical cable 12 needs to be unplugged from the ODN equipment 11 and then inserted into the correct connection port 112 . In this embodiment, by generating the second prompt information before connection, it is helpful for the construction worker to make the connection correctly at the beginning and reduce the number of plugging and unplugging of the optical cable 12 and the ODN device 11, especially when the ODN device 11 has many connection ports.
