Based on the information of the ports at both ends of each segment recorded on the tag, they determine the location of the ports at both ends of each segment, thus gradually locating the port of another device connected to that port. This method requires maintenance personnel to manually flip the tags on each fiber segment and systematically examine the port connections, which is labor-intensive and inefficient. Furthermore, due to the manual flipping and other operations during use, the tags may become damaged, detached, or faded, making the recorded information unclear.

Detailed Implementation
[0011] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0012] As will be known to those skilled in the art, with the development of technology and the emergence of new scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.
[0013] The terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such terms are interchangeable where appropriate; this is merely a way of distinguishing objects with the same attributes in the description of embodiments of this application. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion, so that a process, method, system, product, or apparatus that comprises a series of elements is not necessarily limited to those elements but may include other elements not explicitly listed or inherent to those processes, methods, products, or apparatuses.
[0014] This application provides a port positioning method, apparatus, and device.
[0015] Please refer to Figure 1 This is a schematic diagram of a port communication scenario in related technologies. For example... Figure 1 As shown, this scenario includes: a transmitting port, a transmitting optical module, a receiving optical module, a receiving port, and an optical fiber distribution link.
[0016] The transmitting port is the physical port of the transmitting device, and the receiving port is the physical port of the receiving device. The transmitting optical module is the optical module on the transmitting port, and the receiving optical module is the optical module on the receiving port. The transmitting and receiving optical modules are connected via a fiber optic distribution link. This fiber optic distribution link can be a fiber optic patch cord link or a direct fiber optic link.
[0017] The transmitting optical module can be either an optical transmitter module or an optical transceiver module. The first end of the transmitting optical module can be plugged into the transmitting port, and the second end can be connected to the first end of the fiber optic distribution link. The second end of the fiber optic distribution link can be connected to the first end of the receiving optical module, and the second end of the receiving optical module can be plugged into the receiving port.
[0018] During link probing, the transmitting port can output probe data, which can be input to the transmitting optical module. The transmitting optical module converts the probe data from an electrical signal to an optical signal and transmits the optical signal. The transmitted optical signal can be transmitted to the receiving optical module via the fiber optic distribution link. The receiving optical module converts the optical signal back into an electrical signal and outputs the electrical signal to the receiving port.
[0019] In some application scenarios, the aforementioned sending and receiving devices belong to different management domains, and it is impossible to find the port location of the other device from their respective network management systems.
[0020] For example, the sending device can be a device of the first system, and the receiving device can be a device of the second system. The first and second systems can interface through UNI (User-Network Interface), and they belong to different management domains. Figure 2 As shown, the first system is, for example, a bearer network system, the transmitting device is, for example, a bearer device, and the transmitting port is, for example, a physical port of the bearer device. The second system is, for example, a service system, the receiving device is, for example, a service device, and the receiving port is, for example, a physical port of the service device. Maintenance personnel cannot query the information of the service device ports connected to the bearer device ports from the bearer device's network management system, nor can they query the information of the bearer device ports connected to the service device ports from the service device's network management system, thus failing to determine the location of the bearer device ports connected to the service device ports.
[0021] In related technologies, to determine the connection relationships between device ports belonging to different management domains and locate the positions of interconnected device ports, maintenance personnel typically start from the pigtail connected to the transmitting port and systematically examine the tags attached to each segment of the fiber optic distribution link connected to the transmitting port. Based on the information of the ports at both ends of each segment recorded on the tag, the positions of the ports at both ends of each segment are determined, thus gradually locating the position of the receiving port connected to the transmitting port through the fiber optic distribution link. This method is labor-intensive and resource-intensive, and inefficient. Furthermore, due to the operations such as flipping the tags during use, they may become damaged, detached, or faded, and the recorded information may be unclear. Maintenance personnel may not be able to obtain complete tag information, making accurate port location impossible.
[0022] Therefore, this application provides a port positioning method. In this method, the transmitting optical module and the receiving optical module are modified. An indicator light is provided on the receiving optical module. The transmitting optical module can receive the status control command of the indicator light, combine the status control command with the detection data, and send the status control command along with the detection data to the receiving optical module of the detection data, instructing the indicator light of the receiving optical module to switch to the target status indicated by the status control command.
[0023] Since the receiving optical module is the optical module of the receiving port, it can serve as a clue to locate the receiving port. Maintenance personnel can quickly determine the physical location of the receiving optical module based on the indicator lights indicating the target state, and thus quickly determine the physical location of the receiving port, improving port location efficiency and accuracy.
[0024] The port positioning method of this application embodiment will be described in detail below with reference to the accompanying drawings.
[0025] Please refer to Figure 3 This is a schematic diagram of the interaction flow of a port positioning method according to an embodiment of this application. Figure 3 As shown, the interaction flow of a port positioning method according to an embodiment of this application may include the following steps: S302, status control command for the receiving indicator light of the transmitting optical module.
[0026] The transmitting optical module is the optical module at the transmitting port. The transmitting optical module can be an optical transmitting module or an optical transceiver module.
[0027] The first end of the transmitting optical module can be connected to the transmitting port, and the second end of the transmitting optical module can be connected to the fiber optic distribution link. For example, the first end of the transmitting optical module can be plugged into the transmitting port, and the second end can be connected to the pigtail of the fiber optic distribution link.
[0028] The sending port is the physical port of the sending device. The sending device may be, for example, a bearer device.
[0029] The status control commands for the indicator lights can be sent from the transmitting device to the transmitting optical module.
[0030] Specifically, the transmitting device can connect to the transmitting optical module through a management interface. Maintenance personnel can control the status of indicator lights on the transmitting device, and in response to this control operation, the transmitting device can send status control commands to the transmitting optical module.
[0031] S304, the transmitting optical module combines the status control command with the detection data to obtain composite data.
[0032] The probe data is used for link probing. The probe data is output from the transmitting port to the transmitting optical module, then sequentially transmitted through the transmitting optical module, the fiber optic distribution link, to the receiving optical module, and finally input to the corresponding receiving port of the transmitting port.
[0033] In this embodiment, the transmitting optical module combines the status control command of the indicator light with the detection data output from the transmitting port. This enables the status control command to be input into the receiving optical module along with the detection data output from the transmitting port, instructing the indicator light of the receiving optical module to switch to the target state. This allows maintenance personnel to locate the receiving optical module and thus the receiving port by observing the indicator light in the target state.
[0034] In practice, the transmitting optical module can synthesize the status control command and the detection data in an appropriate manner to obtain the synthesized data.
[0035] In one implementation, the transmitting optical module can synthesize state control commands and detection data using a predefined signal modulation method.
[0036] For example, such as Figure 4 As shown, the predefined signal modulation method can be PAM4 modulation, which is four-level pulse amplitude modulation. The transmitting optical module can use PAM4 modulation to modulate the status control command and the detection data to obtain modulated data, which is the composite data of the status control command and the detection data.
[0037] In related technologies, the modulation method of optical modules with a rate of 10 Gbit / s and below is NRZ (Non-Return-to-Zero). Since the bit rate of the synthesized signal is doubled, PAM4 modulation can adapt to the doubled bit rate.
[0038] S306, the transmitting optical module sends the synthesized data.
[0039] Among them, the transmitting optical module can convert the synthesized data from electrical signal form to optical signal form and transmit the synthesized data in optical signal form.
[0040] The transmitting optical module and the receiving optical module for the probe data are connected via a fiber optic distribution link. The synthesized data in optical signal form is transmitted to the receiving optical module through this fiber optic distribution link.
[0041] Therefore, corresponding to step S306 above, the optical module at the receiving end of the probe data can receive the synthesized data.
[0042] The receiving optical module receives composite data in the form of optical signals, and it can convert the composite data in the form of optical signals into composite data in the form of electrical signals.
[0043] S308, the receiving optical module separates the state control command from the detection data in the synthesized data to obtain the state control command.
[0044] The receiving optical module can separate the state control command and the detection data in the synthesized data in the form of electrical signals through the separation method corresponding to the above synthesis method, so as to obtain the state control command and the detection data.
[0045] For example, suppose the transmitting optical module combines state control commands and probe data using PAM4 modulation. The receiving optical module can demodulate the combined data using PAM4 demodulation to obtain the state control commands and probe data.
[0046] Furthermore, after separating the state control commands and probe data from the synthesized data, the receiving optical module can still obtain the probe data. The receiving optical module can then send the probe data to the receiving port.
[0047] S310, the receiving optical module switches the indicator light of the receiving optical module to the target state indicated by the status control command according to the status control command.
[0048] The receiver optical module is equipped with indicator lights, such as LED (Light-Emitting Diode) indicator lights.
[0049] The status control command for the indicator light can be generated by the transmitting optical module in response to the status control operation of the maintenance personnel. The target status indicated by the status control command can be different depending on the status control operation of the maintenance personnel.
[0050] For example, the status control operation may include a status display mode selection operation. If the operation and maintenance personnel select a constant display mode, the target status indicated by the status control command will be constant; if the operation and maintenance personnel select a flashing display mode, the target status indicated by the status control command will be flashing. Of course, the status control operation may also not include a status display mode selection operation, and the operation and maintenance personnel may not select a status display mode. The target status can be a specified default status, such as a constant display.
[0051] After the indicator light on the receiving optical module switches to the target state, maintenance personnel can quickly locate the receiving optical module and the receiving port by finding the receiving optical module whose indicator light is in the target state.
[0052] In one implementation, to facilitate maintenance personnel in locating the transmitting port and the corresponding receiving port, the transmitting optical module is also equipped with an indicator light. Before S304 above, the port location method may also include the following steps: The transmitting optical module controls the indicator lights to switch to the target state according to the status control command of the indicator lights.
[0053] Therefore, the indicator lights of the transmitting optical module and the corresponding receiving optical module can all switch to the same target state, serving as a visual index for the transmitting and receiving optical modules. Maintenance personnel can quickly locate the transmitting and receiving optical modules in this link probe by finding those whose indicator lights are in the target state. Since the transmitting optical module is plugged into the transmitting port and the receiving optical module is plugged into the receiving port, the transmitting and receiving ports in this link probe can be quickly located, improving port location efficiency and accuracy.
[0054] For example, the transmitting device can be a bearer device, the transmitting port can be a bearer device port, and the transmitting optical module can be an optical transceiver module plugged into the bearer device port. The receiving device can be a service device, the receiving port can be a service device port, and the receiving optical module can be an optical transceiver module plugged into the service device port.
[0055] During link probing, maintenance personnel can control the status of an indicator light on a bearer device port, assuming the selected status display mode is always on. In response to this control, the bearer device sends a status control command to the optical module of that port. The optical module receives this command, switches its indicator light to always on, and combines it with the received probe data from the bearer device port to obtain composite data, which is then sent. This composite data can be transmitted via the fiber optic distribution link to the optical module of the corresponding service device port. The service device port's optical module can then separate the status control command and the probe data from the composite data, and, based on the command, also switches its indicator light to always on. Maintenance personnel can quickly locate the bearer device port and the service device port involved in this link probing by observing the always-on indicator lights on the bearer device and service device optical modules.
