Description

Technical Field

[0001] The present invention relates to the technical field of automated collection of fiber optic patch cords, and particularly to an intelligent fiber optic patch cord automated collection device and system based on radio frequency and optical communication. Background Art

[0002] Currently, in many data centers and communication machine rooms, the management of fiber optic patch cord information mainly relies on manual records and maintenance. This method is not only inefficient but also error-prone. When the fiber optic patch cord connection changes, the staff needs to manually update the relevant records. However, in a large-scale network environment, it is difficult to ensure the timeliness and accuracy of the information. In addition, the existing fiber optic patch cord management means are insufficient in information acquisition. For the service information carried by the fiber optic patch cords, such as service types and service codes, there is a lack of an effective real-time monitoring mechanism. The service identification information will change as the service develops, adjusts, or the network service is upgraded, but the traditional method is difficult to quickly capture these changes. This makes it impossible for network managers to timely understand the actual usage of fiber optic patch cords and difficult to reasonably allocate and optimize network resources according to service requirements. In terms of the identification of fiber optic patch cords, although some fiber optic patch cords may use passive tags, these passive tags usually can only provide limited information and cannot be associated with the real-time service information of the fiber optic patch cords. The passive tags cannot update key information such as the device ports connected by the fiber optic patch cords in real time, and their role is greatly reduced during the dynamic change of the network. This results in difficulty in accurately distinguishing different fiber optic patch cords during network management. Especially when a fault occurs, it is impossible to quickly locate the problem fiber optic patch cord, prolonging the fault repair time and affecting the normal operation of the network. During the information transmission process of fiber optic patch cords, the existing technology lacks a mechanism for dynamically adjusting according to the network environment. Different network environments have different requirements for the signals transmitted by fiber optic patch cords, but the existing technology often adopts a fixed transmission mode and cannot adapt to the complex and changeable network environment, thus affecting the quality and efficiency of fiber optic patch cord information transmission. For the detection of optical signals during the transmission of fiber optic patch cords, the existing photodetectors usually adopt fixed working parameters, making it impossible for the photodetectors to detect optical signals in different situations well, and prone to signal parsing errors or inability to parse, further reducing the reliability of fiber optic patch cord information collection.

[0003] As disclosed in the Chinese patent with the authorization announcement number CN117294353B, an automated mechanical fiber optic cross-connection control method based on intelligent management of fiber optic distribution is provided, including: setting passive RFID tags for the fiber optic cross-connections of each fiber optic device respectively, and setting corresponding RFID readers for the corresponding robotic arms, controlling a preset ODF optical distribution frame to obtain the tag data collected by each of the RFID readers and transmitting it to a preset intelligent distribution manager for data analysis to obtain the real-time status corresponding to different fiber optic devices, establishing a basic fiber optic network within a preset area based on the real-time status, judging whether the total network coverage range of the preset area is within a preset coverage range, and if not, controlling the preset intelligent distribution manager to adjust the positions of the fiber optic cross-connections in each fiber optic device until the coverage range of the basic fiber optic network is consistent with the preset coverage range. This patent has established a regional automated basic fiber optic network, realized the intelligent operation and maintenance of optical communication networks, and thus provided strong support for communication networks. However, the RFID tags used can only provide limited information and cannot be associated with the real-time service information of the fiber optic cross-connections.

[0054] The technical solutions of the present invention will be described in detail below through the drawings and specific embodiments. It should be understood that the specific features in the embodiments of the present invention are detailed descriptions of the technical solutions of the present invention, rather than limitations on the technical solutions of the present invention. Without conflict, the technical features in the embodiments of the present invention and the embodiments can be combined with each other.

[0055] Example 1

[0056] This example introduces an intelligent fiber optic patch cord automatic acquisition device based on radio frequency and optical communication. Referring to Figure 1 , the device includes an information acquisition unit, a transmitting unit, a receiving unit, a radio frequency tag unit, and a data processing unit; among which:

[0057] The information acquisition unit is used to collect the service information and type of the fiber optic patch cord; the service information includes connection device information, device port information, and service identification information; the information acquisition unit is also used to collect the associated environmental data of the fiber optic patch cord.

[0058] A fiber optic patch cord refers to an optical cable used to connect different devices or network nodes. In environments such as data centers and communication machine rooms, fiber optic patch cords are widely used to achieve physical connections between switches, routers, servers, and other network devices. During the process of network device upgrade, maintenance, or network topology adjustment, the start and end ports of the fiber optic patch cord and the connected devices may change, and passive tags cannot update this information in real time. The information acquisition units installed at both ends of the fiber optic patch cord can detect the device ports connected by the fiber optic patch cord in real time through optical communication. When the fiber optic patch cord is connected to a new device port, the information acquisition unit can sense the change in the access port of the optical signal, thereby updating the network link information in a timely manner.

[0059] The connection device information includes information such as the type, name, and number of the device connected by the fiber optic patch cord, which helps to establish a complete network resource map. Through interface interaction with the device management system, the information acquisition unit can obtain detailed information about the device connected by the fiber optic patch cord. For example, when it is identified that the fiber optic patch cord is connected to a switch or a patch panel, information such as the model, serial number, row and column number, frame number, and terminal number of the switch or patch panel can be further obtained, providing more comprehensive data support for network maintenance and fault troubleshooting.

[0060] The device port information includes the connection ports at the start and end of the fiber optic patch cord, which is the key information for constructing the network topology. Accurately collecting the device port information connected by the fiber optic patch cord can clarify the data flow direction and link relationship in the network. The information acquisition unit can identify the connected device port information through optical communication combined with a port identification algorithm. For example, in a communication machine room, the information acquisition unit can identify that one end of the fiber optic patch cord is connected to a port of a switch and the other end is connected to the fiber optic network card port of a server, thereby constructing an accurate connection relationship for this part of the network link.

[0061] The service identification information includes the service type and service code carried by the fiber pigtail. The service identification information will change with the development, adjustment of the service or the upgrade of network services. For example, a fiber pigtail was originally used to carry the data transmission service of the enterprise's internal office automation system. After the enterprise's business expansion, it may be adjusted to carry video conferencing services at the same time. The information collection unit can obtain the change situation of the service identification information in a timely manner through the interaction with the network service management system or the parsing of the network configuration file, and thus accurately update the service situation associated with the fiber pigtail.

[0062] The transmitting unit dynamically selects a modulation mode based on the fiber pigtail type and associated environmental data, and modulates the optical signal emitted by the light source based on the selected modulation mode and the service information; the modulated optical signal is transmitted along the fiber pigtail to the receiving unit;

[0063] The transmitting unit includes a modulator and a modulation control subunit; wherein, the modulator is used to modulate the optical signal emitted by the light source, and the modulated optical signal contains the service information of the fiber pigtail; the modulation control subunit is configured with a modulation control strategy; the modulation control strategy includes dynamically selecting a modulation mode based on the fiber pigtail type and associated environmental data; the fiber pigtail type includes single-mode fiber and multi-mode fiber; the associated environmental data includes service optical wavelength, ambient light intensity, and vibration interference intensity.

[0064] The modulation control strategy specifically includes:

[0065] Assign a value to the fiber characteristic factor F based on the fiber pigtail type; assign a value to the service information factor W based on the service optical wavelength; assign a value to the environmental disturbance factor E based on the ambient light intensity and vibration interference intensity;

[0066] Calculate the comprehensive disturbance index P based on the fiber characteristic factor F, service information factor W, and environmental disturbance factor E. The formula is as follows:

[0067] ;

[0068] Single-mode fiber has the characteristics of low dispersion, low loss, small fiber core diameter, high signal transmission quality, and high spectral efficiency, and can meet the high requirements of quadrature amplitude modulation for signal transmission quality. Multi-mode fiber has a large transmission capacity but has inter-modal dispersion, and the signal transmission quality is relatively lower than that of single-mode fiber. Therefore, intensity modulation is preferably used. An example of assigning a value to the fiber characteristic factor F based on the fiber pigtail type is as follows: if the fiber pigtail type is single-mode fiber, then F is assigned a value of 1; if the fiber pigtail type is multi-mode fiber, then F is assigned a value of 0.4;

[0069] The service optical wavelength is the wavelength of the optical signal emitted by the light source connected by the fiber pigtail. This optical signal is the basis for modulation. Optical signals with short wavelengths have large attenuation and are more suitable for modulation methods that are insensitive to attenuation, such as intensity modulation. Optical signals with long wavelengths have small attenuation and are suitable for modulation methods that are sensitive to dispersion but have high transmission rates, such as quadrature amplitude modulation, and use the low-attenuation characteristics of long-wavelength light to achieve high-speed signal transmission. An example of assigning values to the service information factor W based on the service optical wavelength is as follows: within a certain wavelength range, let the service information factor W be proportional to the service optical wavelength, that is, the longer the service optical wavelength, the larger W; set the maximum value of W to 0.8 and the minimum value to 0.3.

[0070] There may be some optical interferences in the environment where the fiber pigtail is located, which causes a certain degree of distortion when the fiber pigtail transmits the modulated optical signal, increasing the bit error rate. If there is light interference, a modulation method that is insensitive to light interference, such as frequency modulation, can be used. Light interference mainly affects the characteristics of optical signals such as intensity and phase, while the frequency is less directly affected by light interference. In addition, environmental factors may cause vibrations of the fiber pigtail. For example, the blowing of an air conditioner or accidental contact by a person may cause mechanical vibrations of the fiber pigtail, which will also interfere with the transmission of the modulation signal. When there are these vibration disturbances, frequency modulation with a high tolerance to signal distortion can also be selected. An example of assigning values to the environmental disturbance factor E based on the ambient light intensity and vibration interference intensity is as follows: Use an optical power meter to collect the ambient light intensity, place its photosensitive probe at a position near the fiber pigtail that may be interfered with, and it can measure the power of light within a specific wavelength range (if the wavelength of the interfering light is similar to the service optical wavelength, it will cause greater interference and needs to be focused on), as the ambient light intensity. The greater the optical power of the interfering light, the greater the ambient light intensity. Set the ambient light threshold. When the ambient light intensity is greater than the ambient light threshold, there is light interference; install an acceleration sensor on the support structure of the fiber pigtail or an object near it that may transmit vibrations, and measure the vibration amplitude of the optical fiber as the vibration interference intensity. Set the vibration interference threshold. When the vibration interference intensity is greater than the vibration interference threshold, there is vibration interference; if there is both light interference and vibration interference, the environmental disturbance factor E takes a value of 0.6; if there is only one of light interference and vibration interference, E takes a value of 0.3; if there is no light interference and vibration interference, E takes a value of 0.

[0071] The modulation control subunit is also configured with a first threshold of the comprehensive disturbance index and a second threshold of the comprehensive disturbance index ; if the comprehensive disturbance index P is not less than , the modulation mode selected by the modulation control subunit is quadrature amplitude modulation; if P is less than , and not less than , the modulation mode selected by the modulation control subunit is frequency modulation; if P is less than , the modulation mode selected by the modulation control subunit is intensity modulation.

[0072] A first threshold of a comprehensive disturbance index and a second threshold are set as follows: takes a value of 1.8, takes a value of 1.2. In this setting, when the fiber pigtail type is single-mode fiber, the service optical wavelength is long (W = 0.8) and there is no light interference or vibration interference, the comprehensive disturbance index P is exactly equal to . In this case, quadrature amplitude modulation is selected, which can meet the requirements of quadrature amplitude modulation for transmission conditions and give play to its advantage of high spectral efficiency. When there is light interference or vibration interference, then P will decrease, and frequency modulation with anti-interference ability is selected. When multimode fiber is paired with a shorter service optical wavelength, regardless of whether there is light interference or vibration interference, P is less than , that is, intensity modulation is selected.

[0073] The modulator is located on the fiber pigtail, and it modulates the passing optical signal, that is, changes parameters such as the intensity, frequency, or phase of the light in a predetermined manner. The modulation process enables the optical signal to carry service information that can be decoded. Such a modulation mode selection strategy can make a relatively flexible modulation decision according to the nature of the fiber pigtail itself and various demand characteristics of its environment to adapt to different application scenarios of fiber pigtail automatic acquisition.

[0074] The receiving unit detects the optical signal through a photodetector and converts the optical signal into an electrical signal; the receiving unit also adaptively adjusts the working parameters of the photodetector based on the characteristics of the optical signal;

[0075] The receiving unit includes a photodetector and a calibration subunit; wherein, the photodetector converts the optical signal into an electrical signal based on the set bandwidth and bias voltage, and amplifies and filters out noise from the electrical signal based on the set gain coefficient;

[0076] The calibration subunit is configured with an adaptive calibration strategy; the calibration subunit extracts the characteristic parameters of the optical signal and adjusts the working parameters of the photodetector based on the adaptive calibration strategy;

[0077] Since the fiber pigtail may be affected by factors such as temperature and stress during long-term use, the optical signal transmission characteristics may change. At the same time, since fiber pigtails for different service requirements use different modulation methods, if fixed working parameters of the photodetector are adopted, it may not be able to detect the optical signals transmitted by the fiber pigtail well under different modulation modes and different network environments. Configure an adaptive calibration strategy for the receiving unit, monitor and analyze the received optical signals, and adjust the working parameters of the photodetector to ensure that the service information of the fiber pigtail can be accurately parsed under different optical signal intensities and qualities, and ensure the stability and accuracy of the entire device.

[0078] The characteristic parameters of the optical signal include signal intensity and signal frequency;

[0079] Adjusting the working parameters of the photodetector based on the adaptive calibration strategy includes adjusting the gain coefficient of the photodetector, specifically as follows:

[0080] Extract the signal intensity of the optical signal and calculate the mean value, denoted as ; The calibration subunit is configured with a signal intensity threshold ; If is less than , then adjust the gain coefficient of the photodetector, and the formula is as follows:

[0081] ;

[0082] where, G represents the adjusted gain coefficient; represents the basic gain coefficient of the photodetector; is the adjustment coefficient of the gain coefficient, which is set by those skilled in the art based on actual requirements;

[0083] The gain determines the amplification factor after the photodetector converts the optical signal into an electrical signal. When the signal is weak, the gain can be appropriately increased to enhance the intensity of the electrical signal for subsequent signal processing. For example, when the transmission distance of the fiber pigtail is long, increasing the gain can make the weak signal reach the range that can be processed by the subsequent demodulator.

[0084] Adjusting the working parameters of the photodetector based on the adaptive calibration strategy also includes adjusting the bias voltage of the photodetector, specifically as follows:

[0085] Collect the signal intensity of the optical signal at a fixed sampling time interval, and calculate the change rate of the signal intensity after each sampling. The formula is as follows:

[0086] ;

[0087] where, represents the change rate of the signal intensity after the i-th sampling; Represents the signal strength obtained from the i-th sampling; Represents the signal strength obtained from the (i - 1)-th sampling, where i is a positive integer greater than 1; Represents the reference value of the signal strength, which is set by those skilled in the art according to actual requirements;

[0088] The calibration subunit is configured with an intensity change threshold If then adjust the bias voltage of the photodetector, and the formula is as follows:

[0089] ;

[0090] Wherein, Represents the adjusted bias voltage after the i-th sampling; Represents the bias voltage after the (i - 1)-th sampling; Is the adjustment coefficient of the bias voltage, Is the initial bias voltage, both of which are set by those skilled in the art based on actual requirements.

[0091] The bias voltage can adjust the operating point of the photodetector to make it in the best linear operating region. When the intensity range of the optical signal changes, such as the optical signal intensity decreases due to fiber aging, by adjusting the bias voltage, it can ensure that the photodetector can accurately convert the optical signal into an electrical signal and avoid signal distortion. When is greater than 0, it means the signal intensity is increasing; when is greater than the intensity change threshold , then increase the bias voltage to move the operating point of the photodetector upward to avoid signal saturation; when is less than 0, it indicates that the signal intensity is decreasing; if is less than the negative intensity change threshold , then decrease the bias voltage to move the operating point of the photodetector downward to better detect weaker signals.

[0092] The adjustment of the operating parameters of the photodetector based on the adaptive calibration strategy further includes adjusting the bandwidth of the photodetector, specifically as follows:

[0093] Set the frequency detection period of the optical signal; in each frequency detection period, let the sampling frequency be , let the number of sampling points be N, perform a frequency-domain transformation on the optical signal to obtain the spectrum of the optical signal; record the amplitude of the k-th frequency component in the spectrum , where the value range of k is 0, 1,..., N - 1;

[0094] The calibration subunit is set with a high-frequency threshold ; Divide the spectrum of the optical signal into a high-frequency interval based on the high-frequency threshold, and the high-frequency interval is specifically ;

[0095] Calculate the energy proportion of the high-frequency interval, and the formula is as follows:

[0096] ;

[0097] Wherein, represents the energy proportion of the high-frequency interval; represents the index of the high-frequency threshold in the spectrum; that is, the th frequency component in the spectrum corresponds to the high-frequency threshold ;

[0098] The calibration subunit is also provided with a high-frequency proportion threshold and a maximum threshold of the bandwidth , if is greater than , then adjust the bandwidth of the photodetector, and the formula is as follows:

[0099] ;

[0100] Wherein, B represents the adjusted bandwidth; is the adjustment coefficient of the bandwidth, is the initial bandwidth, both of which are set by those skilled in the art based on actual requirements; represents taking the maximum term in the brackets.

[0101] The bandwidth determines the signal frequency range that the photodetector can effectively detect. In a network environment, if the frequency components of the signal change (for example, due to a change in the modulation method), adjusting the bandwidth of the photodetector can make it better match the frequency characteristics of the signal and improve the accuracy of signal detection. When it is detected that the high-frequency components of the signal increase, appropriately broaden the bandwidth of the photodetector to ensure that the signal can be detected completely. At the same time, set the upper limit of the bandwidth, that is, the maximum threshold of the bandwidth , to avoid the problem of excessive noise caused by over-expanding the bandwidth.

[0102] The RF tag unit is used to record the identification information of each fiber jump;

[0103] The radio frequency tag unit includes a radio frequency reader and a passive tag; the passive tag stores identification information corresponding to the fiber jumper; the radio frequency reader activates the passive tag by sending a radio frequency identification signal and receives the identification information of the fiber jumper returned by the passive tag; after detecting the optical signal modulated by the transmitting unit, the receiving unit sends a reading instruction to the radio frequency reader, and the radio frequency reader responds to the reading instruction, reads the identification information of the fiber jumper stored in the passive tag and transmits it to the data processing unit; the identification information includes the unique identifier and physical attribute information of the fiber jumper.

[0104] The most important function of the passive tag is to store the unique identifier of the fiber jumper. The unique identifier is a permanent serial number that remains unchanged throughout the life cycle of the fiber jumper. It is the core information for accurately distinguishing and managing the fiber jumper and is the identity credential of the fiber jumper in the entire network resource management system. No matter how the position of the fiber jumper changes in the network or how the devices it is connected to are updated, this unique identifier can always be used to identify the fiber jumper. For some relatively fixed physical attributes, such as fiber type information, the passive tag can also record them. Physical attribute information such as fiber type (single-mode or multi-mode) usually does not change after the fiber jumper is manufactured, and different fiber types correspond to different uses. When reading the passive tag, the basic physical attributes of the fiber jumper can be quickly obtained without having to determine the fiber type through complex optical detection every time.

[0105] The data processing unit is used to demodulate the electrical signal to obtain the service information of the fiber jumper; the data processing unit also obtains the identification information of the fiber jumper based on the radio frequency tag unit, and binds the service information of the fiber jumper with the identification information and sends it to the cloud server.

[0106] The data processing unit includes a demodulator and a data integration subunit; among them, the demodulator is used to demodulate the electrical signal to obtain the service information corresponding to the fiber jumper;

[0107] The demodulator selects a corresponding demodulation method to demodulate the electrical signal based on the modulation mode of the modulator; for example, for frequency modulation, the demodulator uses a frequency discriminator to detect the change in frequency, converts the frequency change into a change in voltage or current, and then restores the original service information. For phase modulation, the demodulator uses the method of coherent demodulation or differential coherent demodulation to demodulate the service information by comparing the phase of the received signal with the reference phase.

[0108] The data integration subunit is used to bind the service information and identification information of the fiber jumper and send it to the cloud server; the method is as follows:

[0109] Communicate with the RF reader-writer to obtain the identification information of the fiber pigtail and read the service information of the fiber pigtail demodulated by the demodulator; create a fiber pigtail information data packet; the fiber pigtail information data packet includes a service information field and an identification information field; in this data packet, the service information and the identification information are combined in a certain format and distinguished by a specific delimiter or data structure so that the cloud server can accurately parse it; send the fiber pigtail information data packet to the cloud server to complete the automatic collection of fiber pigtail information.

[0111] This embodiment is the second embodiment of the present invention; based on the same inventive concept as Embodiment 1, referring to Figure 2 , this embodiment introduces an intelligent fiber pigtail automatic collection system based on radio frequency and optical communication, including a light source module, a communication module, a display device, a cloud server, and an intelligent fiber pigtail automatic collection device based on radio frequency and optical communication as described in Embodiment 1. Among them:

[0112] The light source module is used to generate an optical signal transmitted along the fiber pigtail; the light source module adopts a light-emitting device existing in the existing communication network, which is a laser used to generate an optical signal to support normal network communication operations. The light-emitting device in the existing communication network can be directly used for signal transmission in the intelligent fiber pigtail automatic collection system without changing the original network structure.

[0113] The intelligent fiber pigtail automatic collection device based on radio frequency and optical communication automatically collects fiber pigtail information based on the optical signal generated by the light source module, including collecting the service information and identification information of the fiber pigtail and generating a fiber pigtail information data packet.

[0114] The communication module is used to send the fiber pigtail information data packet to the cloud server; the communication module realizes the remote data transmission between the intelligent fiber pigtail automatic collection device and the cloud server; in addition to sending data packets to the cloud server, it can also receive instructions and control information from the cloud server to ensure the remote monitoring and management functions of the system.

[0115] The cloud server is used to receive the fiber pigtail information data packet and classify, sort, and store the fiber pigtail information; the cloud server also provides a remote access interface to support remote access to the data and functions on the cloud server. Optionally, the cloud server can also use big data analysis technology to deeply mine and analyze the stored data, such as analyzing the usage frequency of the fiber pigtail, service traffic trends, fault modes, etc., to provide data support for network optimization and decision-making.

[0116] The display device is used to provide an operation interface and a result interface. Among them, the operation interface is used to control the selection of fiber patching, start or stop the information collection of fiber patching. The result interface is used to display the fiber patching information collected by the intelligent fiber patching automatic collection device based on radio frequency and optical communication, facilitating users to intuitively understand the system operation status and collection results.

[0117] For the specific function implementation of each of the above modules, refer to the relevant content in the intelligent fiber patching automatic collection device based on radio frequency and optical communication described in Embodiment 1, which will not be elaborated here.

[0118] Embodiment 3

[0119] Based on the same inventive concept as other embodiments, this embodiment introduces another modulation control strategy of the modulation control subunit.

[0120] The modulation control subunit is further configured with a second modulation control strategy. The second modulation control strategy controls the modulation mode of the modulator based on network environment indicators. The network environment indicators include network delay indicators, bandwidth utilization indicators, and bit error rate indicators. The modulation control subunit is configured with a mapping table of service identification information and network environment indicators. The mapping table records service identification information and the value of each network environment indicator corresponding to each service identification information. The second modulation control strategy is as follows:

[0121] Calculate the comprehensive network environment index, and the formula is as follows:

[0122] ;

[0123] Where, S represents the comprehensive network environment index of fiber patching; D represents the corresponding network delay indicator; U represents the corresponding bandwidth utilization indicator; e represents the corresponding bit error rate indicator; , , are all weight coefficients, which are set by those skilled in the art based on actual requirements;

[0124] The modulation control subunit is further configured with a first threshold and a second threshold for the comprehensive network environment index. If S is less than , the modulation mode of the modulator is set to quadrature amplitude modulation; is the first threshold of the comprehensive network environment index. If S is greater than or equal to , the working mode of the modulator is set to intensity modulation.

[0125] If the comprehensive network environment index S is greater than or equal to , and S is less than , the modulation mode of the modulator is set based on the bit error rate indicator e of fiber patching, specifically as follows:

[0126] If the bit error rate index e is 0, set the modulation mode of the modulator to phase modulation;

[0127] If the bit error rate index e is not 0, set the modulation mode of the modulator to frequency modulation.

[0128] Based on the second modulation control strategy, the modulation control subunit can dynamically adjust the modulation mode of the modulator according to the network environment where the fiber pigtail is located. For example, when the network traffic carried by the fiber pigtail is large and the requirement for transmission speed is high, it automatically switches to a higher-speed modulation method (such as switching from simple intensity modulation to higher-order phase modulation); when the network environment is relatively stable but the requirement for signal quality is higher, it adopts a more interference-resistant modulation method (such as frequency modulation) to select the best modulation method. Such a modulation mode selection strategy can make a more flexible and reasonable modulation decision according to various demand characteristics of the network to adapt to different application scenarios of fiber pigtail automatic acquisition.

[0129] A specific application example of the second modulation control strategy is as follows:

[0130] The second modulation control strategy configured by the modulation control subunit controls the modulation mode of the modulator based on network delay index, bandwidth utilization index, and bit error rate index. The modulation modes of the modulator include intensity modulation (IM), frequency modulation (FM), phase modulation (PM), and quadrature amplitude modulation (QAM). Among them, intensity modulation (IM) carries information by changing the intensity of the optical signal. This modulation mode is simple to implement and has low requirements for equipment, but its anti-interference ability is relatively weak because the optical intensity is easily affected by external factors (such as fiber bending loss, interference from other light sources). And in the case of multiple users or high bandwidth requirements, the information transmission efficiency is limited. Frequency modulation (FM) can make the frequency of the optical signal change according to the information to be transmitted, and has strong anti-interference ability because the frequency is less likely to be affected by small losses and interference during fiber transmission compared to intensity. This modulation mode performs well in an environment with high requirements for signal quality, but the equipment complexity and cost are relatively high, and a wider bandwidth is required to achieve the same data transmission rate. Phase modulation (PM) transmits information by changing the phase of the optical signal. The difference between the phase of the light and the reference signal carries the data. This modulation mode can achieve a higher data transmission rate and has advantages in high-speed communication networks, but the precise detection and recovery of the phase are technically complex and are sensitive to characteristics such as fiber dispersion. Quadrature amplitude modulation (QAM) changes both the amplitude and phase of the optical signal simultaneously, mapping the information to multiple dimensions of the signal. For example, 16-QAM represents 16 different symbols through 4 amplitude and 4 phase combinations. This modulation mode can transmit more information under the same bandwidth and has high spectral utilization, but has high requirements for the linearity of the signal and the accuracy of the equipment, and the signal detection and demodulation process is relatively complex.

[0131] In this embodiment, the network delay index, the bandwidth utilization rate index, and the bit error rate index respectively represent the tolerance degrees of the network where the fiber pigtail is located for network delay, bandwidth utilization rate, and bit error rate. That is, the lower the corresponding index, the stricter the requirement. For example, if the bit error rate index is 0, the requirement for the bit error rate of this fiber pigtail is extremely high, that is, it is required that the bit error rate is as close to 0 as possible. The lower the bandwidth utilization rate index, the lower the tolerance for low bandwidth utilization rate, that is, high bandwidth utilization rate is required. The influences of the network delay index, the bandwidth utilization rate index, and the bit error rate index on the modulation mode are as follows: When the network delay index is low, that is, the network where the fiber pigtail is located has a relatively strict requirement for network delay. At this time, the network needs to quickly transmit the fiber pigtail status and label information, and phase modulation (PM) or quadrature amplitude modulation (QAM) can be selected to improve the transmission rate. For example, in short-distance fiber pigtail communication inside a data center, where the requirement for delay is extremely high, phase modulation or quadrature amplitude modulation can transmit a large amount of fiber pigtail and label detail information in a short time. When the network delay index is low, such as some backup links with low requirements for real-time performance, intensity modulation (IM) can be used, and the modulation and demodulation process is simple and the cost is low. When the bandwidth utilization rate index is low, quadrature amplitude modulation is a good choice. If fiber pigtail communication needs to transmit a large amount of information within a limited bandwidth, such as transmitting the detailed identity information of multiple passive tags and the fiber pigtail performance parameters simultaneously, the multi-dimensional information coding method of QAM can meet the requirements. In scenarios where the bandwidth is relatively abundant and the requirement for transmission efficiency is not high, such as some traditional low-speed network monitoring links, intensity modulation or frequency modulation can meet the basic information transmission requirements. When the bit error rate index is low, such as fiber pigtail communication in a financial data transmission network, frequency modulation or phase modulation is a better choice. Because they have strong anti-interference ability and can effectively reduce the bit errors caused by factors such as fiber micro-bending and external light interference. For networks that can accept a certain bit error rate, such as some internal network monitoring links for non-critical services, intensity modulation can be an economical choice.

[0132] Based on the above requirements, some of the mapping relationships in the mapping table of service identification information and network environment indicators are as follows:

[0133] If the service type is a financial transaction service, such as stock trading, electronic payment, etc., the corresponding network delay index is 0 because financial transactions require extremely low latency, and any latency may cause transaction price fluctuations or transaction failures; the bandwidth utilization rate index is 0. Although the data volume of each transaction is not large, transactions are frequent, and high bandwidth utilization rate is required to ensure that a large amount of transaction information can be transmitted quickly; the bit error rate index is 0, and data accuracy is crucial. Any bit error may cause errors in transaction amounts, account information, etc., leading to serious consequences.

[0134] If the service type is high-definition video stream service, such as high-definition video live broadcast or video-on-demand service, 4K / 8K online video playback, the corresponding network latency index is 0. For live broadcast, too high latency will affect the viewing experience of the audience; for video-on-demand, although the latency requirement is slightly lower, smooth playback still needs to be ensured, so the overall latency requirement is relatively low; the bandwidth utilization rate index is 0, because high-definition video data volume is huge and high bandwidth utilization rate is required to ensure the transmission of information such as high resolution, high frame rate and high color depth of the video; the bit error rate index is 0.5. A small number of bit errors may only cause short-term mosaic or screen distortion in the video picture, which has a certain impact on the overall experience, but the requirement is slightly lower compared to financial transactions.

[0135] If the service type is enterprise office automation service, such as internal document sharing, email, office automation software, etc. within the enterprise, the network latency index is 1. Compared with financial transactions and video services, the office automation service is less sensitive to latency. A slightly longer delay in document transmission or email sending is usually acceptable. The bandwidth utilization rate index is 0.5. The data volume of documents and emails is generally average, but there are many internal users in the enterprise who may use them simultaneously, so a certain bandwidth utilization rate is required, but not an extremely high requirement. The bit error rate index is 0.5. Bit errors may cause document damage or email content errors, but there is usually a certain error correction and retransmission mechanism within the enterprise, so the requirement for the bit error rate is not very strict.

[0136] The first threshold of the network environment comprehensive index is set to 0.33, and the second threshold is set to 0.66; select the modulation mode according to the calculation result of the network environment comprehensive index S as follows:

[0137] If S < 0.33, quadrature amplitude modulation (QAM) is preferentially selected. In this case, it may be a scenario with high requirements for low latency and high bandwidth utilization rate. Lower QAM can meet the requirement of quickly transmitting a large amount of information under a good channel.

[0138] If 0.33 ≤ S < 0.66, further judgment is made: if the bit error rate requirement is high (e = 0), phase modulation (PM) is selected. Because within this comprehensive demand range, lower PM can provide better anti-interference ability to reduce the bit error rate while ensuring a certain bandwidth utilization rate and latency performance. If the bit error rate requirement is not high (e ≠ 0), frequency modulation (FM) is selected. Lower FM may have certain advantages in terms of device complexity and cost compared to other modulation methods when meeting certain latency and bandwidth requirements.

[0139] If S ≥ 0.66, intensity modulation (IM) is selected. This usually corresponds to a scenario with low requirements for both bandwidth utilization rate and latency, and may be sensitive to cost. Lower IM is sufficient to meet the basic information transmission requirements.
