Description

Technical Field

[0001] This application relates to the field of signal processing, specifically to a method, detection device, terminal, and network controller for fiber optic identification. Background Technology

[0002] In optical communication networks, the transmission equipment of two sites is connected by optical fiber. The optical fiber between the two transmission equipment is usually in multiple segments, and each segment can be connected to an optical fiber distribution frame. Through the conversion of the optical fiber distribution frame, the two transmission equipment can be connected through these multiple segments of optical fiber.

[0003] Since each site has multiple transmission devices, and each device needs to connect to multiple other transmission devices, each optical fiber within the site has a corresponding tag for ease of maintenance and management. The tag contains information including connection details within the site and source / destination information for the fiber. This includes at least one of the following: rack information, slot information, and port information for the source and destination ends of the fiber; and the site name and device port location for the sites connected to the source and destination ends. Fiber optic tags are fundamental to daily maintenance, and currently, the information corresponding to each tag is primarily determined manually.

[0004] In related technologies, when the label information of an optical fiber is incorrect, or the label is old, blurred, or lost, the label information can only be determined manually. Since a site's transmission equipment has many optical fibers, determining the label information of a particular fiber is extremely difficult. Moreover, when two sites are not connected by a direct optical fiber, manual investigation methods are unlikely to determine the source and destination information of the site where the optical fiber is located. Summary of the Invention

[0005] This application provides a method for optical fiber identification, which is used to quickly and accurately obtain optical fiber information of a target optical fiber.

[0006] Polarization state is a property of light. When an optical signal is transmitted in an optical fiber, it can have two independent vibration directions perpendicular to the transmission direction. Each vibration direction can be called a polarization of the optical signal. The magnitude and phase difference of the electric field intensity in these two polarization directions can change independently. The polarization state parameter is determined by the amplitude ratio and phase difference between the two polarizations. If the two polarizations experience different losses, fiber delays, dispersion, or nonlinearities, the amplitude ratio and phase difference between the two polarizations of the same optical signal at a certain moment may change, thus altering the polarization state parameter of the optical signal. For example, performing target manipulation on the optical fiber may cause a change in the polarization state parameter of the optical signal transmitted through the fiber.

[0007] The first aspect of this application provides a method for optical fiber identification, applied to quickly and accurately obtain optical fiber information of a target optical fiber. The method includes: a detection device acquiring polarization state parameters of a first optical fiber; then the detection device determining a corresponding first operation code based on the polarization state parameters of the first optical fiber, the first operation code indicating a first operation performed by a terminal on the first optical fiber; the detection device sending a first event notification, the first event notification including the optical fiber information of the first optical fiber and the first operation code, the first event notification being used to determine the optical fiber information of the target optical fiber.

[0008] In this possible implementation, the detection device sends a first event notification, enabling the terminal to determine the fiber information of the target fiber in which the terminal performs the target operation. The user can then easily and accurately obtain the fiber information of the fiber through the terminal.

[0009] In one possible implementation of the first aspect, the detection device sends a first event notification, including:

[0010] The detection device sends a first event notification to the terminal. The first event notification includes the fiber information of the first optical fiber and the first operation code. The first event notification is used by the terminal to determine the fiber information of the target optical fiber.

[0011] In this possible implementation, the detection device directly sends a first event notification containing fiber optic information of the first fiber to the terminal, thereby enabling the terminal to directly obtain the fiber optic information of the first fiber and thus determine the fiber optic information of the target fiber. This reduces the involvement of the network controller and minimizes the waste of network resources.

[0012] In one possible implementation of the first aspect, the detection device sends a target event notification, including:

[0013] The detection device sends a first event notification to the network controller. The first event notification includes the fiber information of the first optical fiber and the first operation code. The first event notification is used by the network controller to determine the fiber information of the target optical fiber.

[0014] In this possible implementation, the terminal obtains the first event notification from the network controller. The fiber information of the target fiber is sent to the terminal by the network controller. The terminal no longer needs to determine whether the fiber information of the first fiber is the fiber system information of the target fiber, which makes the terminal determine the fiber information of the first fiber faster and reduces the waste of network resources.

[0020] In one possible implementation of the second aspect, the target event notification is a first event notification sent by the detection device. The fiber information for determining the target fiber includes fiber information of the first fiber and a first operation code. The first operation code indicates a first operation performed by the terminal on the first fiber. The terminal determines the fiber information of the target fiber based on the target event notification, including: if the first operation code is the same as the target operation code, then the terminal determines that the fiber information of the first fiber is the fiber information of the target fiber.

[0021] In this possible implementation, the terminal receives the first event notification sent by the detection device, which reduces the involvement of the network controller and minimizes the waste of network resources.

[0022] In one possible implementation of the second aspect, the target event notification is a second event notification sent by the network controller, and the fiber information used to determine the target fiber includes the fiber information of the target fiber, which is determined by the network controller.

[0023] In this possible implementation, the terminal obtains the first event notification from the network controller. The fiber information of the target fiber is sent to the terminal by the network controller. The terminal no longer needs to determine whether the fiber information of the first fiber is the fiber system information of the target fiber, which makes the terminal determine the fiber information of the first fiber faster and reduces the waste of network resources.

[0024] In one possible implementation of the second aspect, the terminal acquires a target operation code, including: the terminal generates a target operation code that indicates a target operation to be performed on the target optical fiber.

[0025] In this possible implementation, the terminal generates its own operation code without the need for the network controller, thus reducing the waste of network resources.

[0028] In this possible implementation, the terminal obtains the target operation code from the network controller, thereby enabling the network controller to determine the operation performed by the terminal on the optical fiber and to determine the fiber information of the target optical fiber.

[0029] In one possible implementation of the second aspect, the target operation includes: vibrating the target optical fiber for a specified time and at a specified frequency; or shaking the target optical fiber for a specified time and according to a specified pattern.

[0066] This application provides a method for optical fiber identification, which can be used to obtain the optical fiber information of the optical fiber simply and accurately.

[0067] The embodiments of this application are described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. As those skilled in the art will recognize, with the development of technology and the emergence of new scenarios, the technical solutions provided by the embodiments of this application are also applicable to similar technical problems.

[0068] 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 data can be interchanged where appropriate so that the embodiments described herein can be implemented in a sequence other than that illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0069] Please see Figure 1 In optical communication networks, the transmission equipment of two sites is connected by optical fiber. The optical fiber between the two transmission equipment is usually in multiple segments, and each segment can be connected to an optical distribution frame (ODF). Through the ODF, the two transmission equipment can be connected through these multiple segments of optical fiber.

[0070] Because each site has multiple transmission devices, and each device needs to connect to multiple other transmission devices, each optical fiber within the site has a corresponding tag for ease of maintenance and management. The tag contains information including connection information within the site and source / destination information for the fiber. For example, it may include at least one of the following: rack information, slot information, and port information for the source and destination ends of the fiber; and at least one of the following: site name and device port location for the sites connected to the source and destination ends of the fiber. For example... Figure 1 The label for fiber optic cable 1 is as follows: (1. Intra-site fiber optic information: From: Cabinet 1, Subrack 1, Slot 2; To: ODF 1, Frame 1, Row 1, Column 1; 2. Inter-site fiber optic information: Source end name: Cabinet 1; Destination end name: Cabinet 2). Fiber optic cable labels are fundamental to daily maintenance, and currently, the information corresponding to the fiber optic cable labels is mainly determined manually.

[0071] Please see Figure 2 In related technologies, when the label information of an optical fiber is incorrect, or the label is old, blurred, or lost, the label information can only be determined manually. Since a site's transmission equipment has many optical fibers, determining the label information of a particular fiber is extremely difficult. Moreover, when two sites are not connected by a direct optical fiber, i.e., when there is an intermediate optical fiber distribution frame, manual inspection methods are unlikely to determine the source and destination information of the optical fiber.

[0072] Please see Figure 3In this embodiment of the application, after the detection device obtains the polarization state parameters of the target optical fiber, it determines the corresponding target operation code based on the polarization state (SOP) parameters of the target optical fiber. The target operation code instructs the terminal to perform a target operation on the target optical fiber. The detection device sends a first event notification, which includes the optical fiber information of the target optical fiber and the target operation code. The first event notification is used by the terminal to determine the optical fiber information of the target optical fiber.

[0073] Polarization state is a property of light. When an optical signal is transmitted in an optical fiber, it can have two independent vibration directions perpendicular to the transmission direction. Each vibration direction can be called a polarization of the optical signal. The magnitude and phase difference of the electric field intensity in these two polarization directions can change independently. The polarization state parameter is determined by the amplitude ratio and phase difference between the two polarizations. If the two polarizations experience different losses, fiber delays, dispersion, or nonlinearities, the amplitude ratio and phase difference between the two polarizations of the same optical signal at a certain moment may change, thus altering the polarization state parameter of the optical signal. For example, performing target manipulation on the optical fiber may cause a change in the polarization state parameter of the optical signal transmitted through the fiber.

[0074] In this embodiment of the application, the first event notification of the detection device can be sent to the terminal or to the network controller, which will be described separately below:

[0075] 1. The detection equipment sends a first event notification to the network controller.

[0076] Please see Figure 4 One step of the fiber optic identification method in this application embodiment includes:

[0077] 401. The terminal sends an operation code request to the network controller.

[0078] The terminal sends an operation coding request to the network controller, which instructs the network controller to send a target operation code to the terminal; accordingly, the network controller receives the operation coding request sent by the terminal.

[0079] In this embodiment, the terminal sends an operation code request to the network controller to obtain the target operation code; the terminal may also generate the target operation code and then send the target operation code to the network controller, and the network controller will not send the target operation code to the terminal; there are multiple ways for the terminal to obtain the target operation code, and no specific method is limited here.

[0080] The terminal can be a dedicated terminal device or a mobile phone with corresponding software; no specific limitation is made here.

[0081] 402. The network controller sends the target operation code to the terminal.

[0082] The network controller generates a target operation code based on the operation code request and sends the target operation code to the terminal. The target operation code indicates the target operation that the terminal needs to perform on the target fiber. Correspondingly, the terminal receives the target operation code sent by the network controller. Specifically, the network controller can generate the target operation code randomly, or it can select an operation code from a preset operation code library as the target operation code; the specific method is not limited here.

[0083] The network controller can be a standalone network controller specifically designed for this application embodiment, or it can be a network management device including corresponding software; no specific limitation is made here.

[0084] 403. The terminal performs target operations on the target optical fiber.

[0085] The terminal performs the target operation on the target fiber according to the target operation in the target operation code.

[0086] Specifically, the target operation can be vibration of the target optical fiber according to at least one of a specified event, a specified frequency, and a specified pattern, with the aim of influencing the polarization state parameters of the target optical fiber. For example, the terminal includes a vibration unit that controls the vibration unit to vibrate the target optical fiber at a frequency of 100Hz for 2 seconds, then stop vibrating for 1 second, and then vibrate at a frequency of 200Hz for 3 seconds. The target operation can also be shaking of the target optical fiber according to at least one of a specified event and a specified pattern, with the aim of influencing the polarization state parameters of the target optical fiber. For example, the terminal instructs the user to shake the target optical fiber for 2 seconds, then stop for 1 second, and then shake for 3 seconds. The terminal can also control a shaking unit that shakes the target optical fiber for 1 second, then stops for 2 seconds, and then shakes for 1 second. The target operation can take many forms, and no specific limitation is made here.

[0087] 404. The detection equipment obtains the polarization state parameters of the first optical fiber.

[0088] The detection equipment acquires the polarization state parameters of the first optical fiber. Polarization state is a property of light. When an optical signal is transmitted in an optical fiber, it can have two independent vibration directions perpendicular to the transmission direction. Each vibration direction can be called a polarization of the optical signal. The magnitude and phase difference of the electric field intensity in these two polarization directions can change independently. The polarization state parameters are determined by the amplitude ratio and phase difference between the two polarizations. If the two polarizations experience different losses, fiber delays, dispersion, or nonlinearities, the amplitude ratio and phase difference between the two polarizations of the same optical signal at a given moment may change, thus altering the polarization state parameters of the optical signal. For example, performing target manipulation on the optical fiber may cause changes in the polarization state parameters of the optical signal transmitted through that fiber.

[0089] The testing equipment can be a standalone testing equipment specifically used in the embodiments of this application, or it can be a testing module or testing unit included in network equipment such as fiber optic distribution frames and cabinets. No specific limitation is made here.

[0090] The polarization state parameter includes at least one of the amplitude ratio and phase difference, in addition to, such as Figure 5 As shown, the polarization state of an optical signal can also be represented by a Poincare sphere. Each point on the cross section corresponds to a different polarization state. The three tangent cross sections of the Poincare sphere represent the three component parameters of the polarization state, namely S1, S2, and S3, respectively. The specifics are not limited here.

[0091] 405. The detection equipment determines the corresponding first operation code based on the polarization state parameters.

[0092] Please see Figure 6 The detection device determines the corresponding first operation code based on the polarization state parameters of the first optical fiber. The first operation code indicates the first operation performed by the terminal on the first optical fiber.

[0093] Specifically, the detection equipment determines the first operation performed on the first optical fiber based on the polarization state parameters of the first optical fiber, and then determines the corresponding first operation code based on the first operation. For example... Figure 6 The detection equipment determines the first operation performed on the first optical fiber based on the waveform of the polarization state parameters of the first optical fiber: shaking for two seconds, stopping for one second, and then shaking for two seconds again; the detection equipment then determines the first operation code corresponding to the first operation as: A.2s, B.1s, A.2s.

[0094] The first operation code can be generated instantly by the detection device based on the first operation, or it can be selected by the detection device from a pre-set operation code library. The specific choice is not limited here.

[0095] 406. The detection device sends a first event notification to the network controller.

[0096] The detection device sends a first event notification to the network controller. This first event notification includes fiber optic information of the first fiber and a first operation code. The detection device has fiber optic information for all fibers, and this first event notification is used to determine the fiber optic information of the target fiber. Accordingly, the network controller receives the first event notification sent by the detection device.

[0097] 407. The network controller determines the fiber optic information of the target fiber based on the first event notification.

[0098] If the network controller determines that the first operation code in the first event notification sent by the detection device is the same as the target operation code sent by the network controller to the terminal, then the network controller determines that the fiber information of the first fiber in the first event notification sent by the detection device is the fiber information of the target fiber, that is, the first fiber is the target fiber.

[0099] 408. The network controller sends a target event notification to the terminal.

[0100] The network controller sends a target event notification to the terminal, which includes fiber optic information of the target fiber. The terminal then receives the target event notification from the network controller.

[0101] 409. The terminal determines the fiber optic information of the target fiber.

[0102] The terminal determines that the fiber optic information in the target event notification is the fiber optic information of the target fiber.

[0103] In this embodiment of the application, the detection device sends the first event notification to the network controller. The detection device can also send it to the terminal, as described in detail below:

[0104] 2. The detection equipment sends the first event notification to the terminal.

[0105] Please see Figure 7 One step of the fiber optic identification method in this application embodiment includes:

[0106] 701. The terminal generates the target operation code.

[0107] The terminal generates a target operation code, which indicates that a target operation should be performed on the target optical fiber. Specifically, the terminal can generate the target operation code randomly, or it can select an operation code from a preset operation code library as the target operation code; the specific method is not limited here.

[0108] 702. The terminal performs target operations on the target optical fiber.

[0109] In this embodiment of the application, step 702 is the same as step 403, and the details will not be repeated here.

[0110] 703. The detection equipment obtains the polarization state parameters of the first optical fiber.

[0111] In this embodiment of the application, step 703 is the same as step 404, and the details will not be repeated here.

[0112] 704. The detection equipment determines the corresponding first operation code based on the polarization state parameters.

[0113] In this embodiment of the application, step 704 is the same as step 405, and the details will not be repeated here.

[0114] 705. The detection equipment sends a target event notification to the terminal.

[0115] The detection device sends a target event notification to the terminal. This target event notification includes fiber optic information of the first optical fiber and a first operation code. The first event notification is used to determine the fiber optic information of the target optical fiber. Accordingly, the terminal receives the first event notification sent by the detection device.

[0116] 706. The terminal determines the fiber optic information of the target fiber.

[0117] If the terminal determines that the target operation code is the same as the first operation code in the first event notification sent by the detection device, then the terminal determines that the fiber information of the first fiber in the first event notification sent by the detection device is the fiber information of the target fiber, that is, the first fiber is the target fiber.
