Description
Technical Field
[0001] This application relates to the field of optical communication, and more particularly to a management method and an optical network device for optical networks. Background Technology
[0002] Currently, Ethernet passive optical network (EPON) is evolving towards 10G EPON and 50G PON (passive optical network, PON). During the evolution and deployment of EPON to 50G PON, it is necessary to build new 50G PON optical line terminations (OLTs), and connect them to the optical network equipment via fiber patching.
[0003] However, in actual use, there may be abnormal terminal services in optical networks, resulting in poor communication performance and affecting user experience. Summary of the Invention
[0004] This application provides a management method and an optical network device for optical networks, which can improve communication performance and user experience.
[0005] Firstly, a management method for an optical network is provided. This method can be executed by an OLT, by a module applied to the OLT (such as a processor, chip, or chip system), or by a logical node, logical module, or software that can implement all or part of the OLT functions.
[0006] The method includes: determining that the device type of the optical network device is a preset type, the optical network device including an optical network termination (ONT) or an optical network unit (ONU); sending a first message and / or a second message, the first message being used to shut down the optical network device, and the second message being used to indicate that the device type of the optical network device is incorrect.
[0007] Based on this method, by determining the device type of optical network equipment, it is possible to shut down optical network equipment of a preset type or to indicate that the device type is incorrect, which facilitates the replacement of the optical network equipment in the future.

The following descriptions of the embodiments of this application do not constitute a limitation on the scope of protection of this application.
[0054] To facilitate understanding of the technical solutions of the embodiments of this application, a brief introduction to the relevant technologies of this application is given below.
[0055] (1) ONT, commonly known as optical modem, refers to a network device that transmits optical signals through optical fiber media and modulates and demodulates optical signals into other protocol signals.
[0056] (2)OLT refers to terminal equipment used to connect fiber optic trunk lines.
[0057] (3) ONU refers to a network device that converts optical signals into other signals through fiber optic access.
[0058] The technical solution of this application is applicable to optical network systems, such as EPON, Fabry-Perot (FP) EPON ONT, distributed feedback (DFB) EPON, 10G EPON, 50G PON, future optical network systems, or integrated systems of multiple optical network systems.
[0059] Figure 1 This is a schematic diagram of the structure of an optical network system according to an embodiment of this application. Figure 1 As shown, the optical network system 100 includes an OLT 101 and an optical network device 102, which are connected by optical fiber.
[0060] One end of OLT 101 connects upwards to an upper-layer network to complete the access of uplink signals. The upper-layer network can be an Internet Protocol (IP) backbone or a Public Switched Telephone Network (PSTN). The other end of OLT 101 connects downwards to optical network device 102 via an Optical Distribution Network (ODN) to complete the transmission of downlink signals and realize functions such as control, management, and ranging of optical network device 102. In this embodiment, the ODN includes optical fiber for transmitting optical signals.
[0061] In this embodiment of the application, OLT 101 may include an EPON OLT and / or a 50G PON OLT.
[0062] The OLT 101 can be deployed in locations such as laboratories, residential communities, streets, and central control stations. One OLT 101 can connect to multiple optical network devices 102. Figure 1 Only one optical network device 102 is shown in the illustration. It should be understood that the optical network system may include a greater number of optical network devices 102, and this application does not limit this.
[0063] In some embodiments, the OLT 101 may provide communication functionality to enable communication with optical network devices.
[0064] In other embodiments, OLT 101 may provide processing capabilities for determining the device type of the optical network device.
[0065] Optical network device 102 can be an ONU and / or an ONT. One end of optical network device 102 connects upwards to the OLT via the ODN, and the other end connects downwards to terminal devices, such as computers, landline telephones, etc. Optical network device 102 works in conjunction with OLT 101 to implement Ethernet Layer 2 and Layer 3 functions, providing users with voice, data, and multimedia services.
[0066] In some embodiments, the optical network device 102 can receive data sent by the OLT 101 and respond to commands issued by the OLT 101 to make corresponding adjustments.
[0067] In other embodiments, the optical network device 102 may cache its device information and send it to the uplink in the transmission window allocated by the OLT 101.
[0068] It should be noted that an ONT can be part of an ONU. The difference between an ONT and an ONU is that an ONT can be located directly at the user end, while an ONU is an optical network unit that may have other networks, such as Ethernet, between it and the user. An ONU can connect to gateway devices at various types of Digital Subscriber Line (DSL) or Ethernet access points, and the gateway devices are then connected to network terminals.
[0069] It should be understood that this application does not limit the number of devices included in an optical network system, and the optical network system may include more than [number of devices]. Figure 1 More or fewer devices.
[0070] It should be noted that the optical network system described in the embodiments of this application is for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and does not constitute a limitation on the technical solutions provided in the embodiments of this application. As those skilled in the art will know, with the evolution of network architecture and the emergence of new service scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.
[0071] Figure 2 This is a schematic diagram of a converged optical network system provided in this application. Figure 2As shown, when there is a surplus of optical splitters in the network (i.e., a surplus of more than 50% in the existing network), 144-core optical fibers and 4-core optical fibers are used as the backbone and distribution cables to achieve Level 1 and Level 2 optical splitting. By multiplexing the drop cables, at the Level 2 splitting point, 50G PON ONT, 10G EPON ONT, and DFB EPON ONT are connected via jumpers. With the gradual development of optical networks, the ultimate goal is to replace EPON with 50G PON. This means that the existing FP EPON ONTs in EPON also need to be gradually replaced by DFB EPON ONTs, 10G EPON ONTs, and 50G PON ONTs, thereby realizing the evolution and deployment of EPON to 50G PON.
[0072] It should be noted that the existing EPON and 50G PON use different optical fibers within the same transmission line. Figure 2 For example, the FP EPON ONT receives downlink signals from the EPON OLT; the EPON OLT receives uplink signals from the FP EPON ONT; the 50G PON ONT, 10G EPON ONT, and DFB EPON ONT receive downlink signals from the 50G PON OLT; and the 50G PON OLT receives uplink signals from the 50G PON ONT, 10G EPON ONT, and DFB EPON ONT. Furthermore, based on the different wavelengths of the uplink signals, the uplink signals transmitted by different ONTs are separated. In other words, the optical signals of EPON and 50G PON do not interfere with each other.
[0073] Different types of optical network systems may use different standard wavelengths. Below, we present examples of standard wavelengths for several optical network systems, using Tables 1 and 2 as examples. Table 1 shows the uplink and downlink standard wavelengths defined by the Institute of Electrical and Electronics Engineers (IEEE), and Table 2 shows the uplink and downlink standard wavelengths defined by the Telecommunication Standards Subcommittee of the International Telecommunication Union (ITU-T).
[0074] Table 1
[0075]
[0076] Table 2
[0077]
[0078] It should be noted that EPON ONTs with an uplink wavelength of 1310±50nm are usually called FP EPON ONTs, or broadband optical network terminals; while EPON ONTs with an uplink wavelength of 1310±20nm are usually called DFB EPON ONTs, or narrowband optical network terminals.
[0079] Understandable, in such Figure 2 In the converged optical network system shown, the uplink wavelength range of FP EPON ONT is 1260nm-1360nm, the uplink wavelength range of DFB EPON ONT is 1290nm-1330nm, the uplink wavelength range of 10G EPON ONT is 1260nm-1280nm, and the uplink wavelength range of 50G PON ONT is 1284nm-1288nm.
[0080] Figure 3 This diagram illustrates the wavelength distribution in different types of optical networks. The cutoff region represents the wavelength range where optical signals cannot transmit effectively, and the water peak region represents the wavelength range where optical signal transmission loss increases sharply. For example... Figure 3 As shown, the wavelength range of the FP EPONONT covers the wavelength range of other types of ONTs.
[0081] In optical network systems, if other types of ONTs are mistakenly connected as FP EPON ONTs, the overlapping wavelength ranges will prevent the OLT from separating the uplink signals of different ONTs by wavelength, thus affecting the ONT's services.
[0082] As an example, during the evolution and deployment from EPON to 50G PON, it is typically necessary to build a new 50G PON OLT, which supports the coexistence of 50G PON ONT, 10G EPON ONT, and DFB EPON ONT. The 50G PON tri-mode ports can simultaneously support data transmission through 50G PON ONT channels, 10G EPON ONT channels, and DFB EPON ONT channels.
[0083] In practical use, optical networks may experience terminal service anomalies, leading to poor communication performance and impacting user experience. Analysis revealed that, for example... Figure 4 As shown, this problem usually occurs because technicians mistakenly connect the FP EPON ONT to the 50G PON during the process of connecting the fiber jumper to the ONT.
[0084] When connecting an ONT via fiber optic jumper, an FP EPON ONT was mistakenly connected to a 50G PON. This resulted in the simultaneous presence of 50G PON ONTs, 10G EPON ONTs, DFB EPON ONTs, and FP EPON ONTs within the 50G PON network. Since the uplink wavelength ranges of these ONTs all fall within the uplink wavelength range of the FP EPON ONT, the OLT cannot separate the uplink signals from different ONTs due to the overlapping uplink wavelengths. This impacts the uplink services of the 50G PON. Furthermore, the downlink wavelength range of the 50G PON also falls within the uplink wavelength range of the FP EPON ONT, meaning that the uplink signals from the FP EPON ONT interfere with the downlink signals of the 50G PON. This leads to abnormal terminal services, poor communication performance, and a negative user experience.
[0085] To address the aforementioned issues, this application provides a management method for optical networks. The method involves determining that the device type of an optical network device is a preset type; sending first information and / or second information, where the first information is used to shut down the optical network device, and the second information is used to indicate that the device type is incorrect. Based on this optical network management method, by determining the device type of the optical network device, it is possible to shut down the optical network device of the preset type or to indicate that the device type is incorrect. This facilitates subsequent replacement of the optical network device, eliminates the impact of the preset-type optical network device on other devices in the optical network, avoids disruption to communication services, and thus improves communication performance.
[0086] The following is combined with Figure 1 The schematic diagram of the optical network system shown illustrates the optical network management method provided in this application, using the OLT executing the optical network management method provided in this application as an example. It should be noted that in the following embodiments of this application, the message names of the OLT, the names of each parameter, or the names of each piece of information are merely examples, and may be other names in other embodiments. The method provided in this application does not specifically limit these names.
[0087] It is understood that in the embodiments of this application, the OLT can perform some or all of the steps in the embodiments of this application. These steps or operations are merely examples, and the embodiments of this application can also perform other operations or variations of various operations. Furthermore, the steps can be performed in different orders as presented in the embodiments of this application, and it is not necessary to perform all the operations in the embodiments of this application.
[0088] See Figure 5The flowchart below illustrates a method for managing an optical network provided in this application. This method may include the following steps:
[0089] S510, OLT determines the device type of the optical network device to be the preset type.
[0090] Optical network equipment includes ONT or ONU.
[0091] As an example, the default type is broadband optical network terminal.
[0092] S520, the OLT sends a first message and / or a second message. The first message is used to shut down the optical network device, and the second message is used to indicate that the device type of the optical network device is incorrect.
[0093] As one possible implementation, the OLT sends first information to an optical network device of a preset device type. Correspondingly, the optical network device receives the first information and, in response to the first information, shuts down the optical network device.
[0094] As one possible implementation, the OLT sends a second message to the management device. The management device then receives this second message, enabling optical network technicians to replace the optical network equipment based on it.
[0095] Based on the above scheme, by determining the device type of optical network equipment, it is possible to shut down optical network equipment of the preset type or to indicate that the device type is incorrect, which facilitates the replacement of the optical network equipment in the future. This can eliminate the impact of optical network equipment of the preset type on other devices in the optical network, avoid the impact on communication services, and thus improve communication performance.
[0096] As one possible implementation, the OLT can determine that the device type of the optical network device is a preset type by confirming that the device information of the optical network device is the same as the preset device information. This application does not specifically limit the implementation of the OLT in determining that the device type of the optical network device is a preset type.
[0097] As one possible implementation, the device information includes at least one of the following: manufacturer information, model information, software version information, or laser type.
[0098] For example, manufacturer information can be information about the manufacturer of the optical network equipment; model information can be the model of the optical network equipment; software version information can be the version of the software used by the optical network equipment; and laser type can be the type of laser contained in the optical network equipment, such as a broadband optical network terminal.
[0099] In addition, the preset device information and the device information of optical network devices may also include other information, such as the device's physical (media access control, MAC) address.
[0100] In some implementations, the laser type can also be referred to as the device type.
[0101] Understandably, before the OLT can determine the device information of the optical network device and the preset device information, it needs to obtain the device information of the optical network device and the preset device information.
[0102] Optional, such as Figure 6 As shown, the method in this embodiment may include: S503, the optical network device sends its device information to the OLT. Correspondingly, the OLT receives the device information of the optical network device.
[0103] For example, when an optical network device is first activated, it sends device information to the OLT.
[0104] Optional, such as Figure 6 As shown, the method of this embodiment may include: S502, the OLT sends third information to the optical network device, the third information being used to instruct the optical network device to report the device information of the optical network device; correspondingly, the optical network device receives the third information, and in response to the third information, the optical network device sends the device information of the optical network device to the OLT.
[0105] Optional, such as Figure 6 As shown, the method in this embodiment may include: S501, the management device sends preset device information to the OLT. Correspondingly, the OLT receives the preset device information from the management device.
[0106] As one possible implementation, optical network technicians store preset device information in the management device, which then sends the preset device information to the OLT via the Simple Network Management Protocol (SNMP).
[0107] As another possible implementation, in the original EPON, the OLT stores the device information of the optical network devices in the EPON. The EPON OLT sends the stored device information of the EPON optical network devices to the management device. Correspondingly, the management device receives the device information of the EPON optical network devices. In such a case... Figure 7 In the application scenario shown, the management device identifies the pre-defined device information based on the reported device information of the EPON optical network devices. The management device then sends the pre-defined device information to the OLT via SNMP.
[0108] It should be noted that there is no strict order between steps S502 and S503 and S501. Step S501 can be executed first, followed by steps S502 and / or S503, or steps S502 and / or S503 can be executed first, followed by step S501. This application does not impose any specific restrictions on this.
[0109] Furthermore, after the optical network equipment has been identified, the above method must be repeated when a new optical network equipment is added to the optical network system, or when the technicians replace the optical network equipment. If the information of the newly added or replaced optical network equipment differs from the preset equipment information, the OLT can send a fourth message to the management device. This fourth message indicates that the incorrect equipment type in the previously sent second message has been replaced.
[0110] Based on the above scheme, through the cooperation between management equipment, OLT and optical network equipment, it is possible to detect optical network equipment of a preset type by determining the equipment type of the optical network equipment. For optical network equipment of the preset type, it is possible to shut down the optical network equipment or indicate that the equipment type is incorrect, which facilitates the replacement of the optical network equipment in the future. It is possible to isolate optical network equipment of the preset type of broadband optical network terminal, eliminate the impact of optical network equipment of the preset type on other equipment in the optical network, avoid the impact on communication services, thereby improving communication performance and promoting the deployment of EPON towards 50G PON.
[0111] The above implementation method does not require upgrading optical network equipment, which helps to reduce the implementation complexity of optical network equipment.
[0112] like Figure 8 In the application scenario shown, the management system can upgrade the software of the optical network device, enabling the optical network device to determine its own laser type and report the laser type, so that the OLT can know the laser type and determine whether the laser type is the preset type.
[0113] As an example, the management system responds to an upgrade command and upgrades the optical network equipment.
[0114] As an example, the management system upgrades the software of optical network devices to store preset wavelength ranges. The optical network device determines its laser type based on the actual wavelength range of its laser and the preset wavelength range. For instance, the actual wavelength range of the laser in the optical network device is [a, b], and the preset wavelength range is [c, d], where a, b, c, and d are all positive numbers. When a ≤ c and b ≥ d, the laser type of the optical network device is determined to be a broadband optical network terminal. Therefore, the device information sent by the optical network device to the OLT includes the laser type as a broadband optical network terminal.
[0115] In one implementation of this embodiment, the management system can upgrade the software of the optical network device, enabling the optical network device to independently determine whether its laser type is a preset type and report the determination result. This allows the OLT to send first information and / or second information based on the determination result. For example, if the determination result indicates that the laser type is a preset type, the OLT sends the first information and / or the second information.
[0116] In one implementation of this embodiment, the management system can upgrade the software of the optical network device, enabling the optical network device to determine whether its laser type is a preset type, and shut down the laser and / or report the second information when the laser type is determined to be a preset type; after receiving the second information, the OLT can send the second information to the management system, so that the management personnel can know the reason for the optical network device being shut down.
[0117] It is understandable that any of the aforementioned management methods for optical networks can be applied to scenarios where EPON ONTs are accessed through tri-mode ports of 50G PON. Furthermore, before executing steps S502 and / or S503, the OLT and the optical network equipment have already established a connection based on the multi-point control protocol (MPCP), and completed operation administration and maintenance (OAM) and user authentication, enabling communication and interaction between the OLT and the optical network equipment.
