Description

Technical Field

[0001] The present invention relates to the technical field of automatic fiber patching collection, and in particular to intelligent automatic fiber patching collection equipment and system based on wireless radio frequency and optical communication. Background Art

[0002] At present, in many data centers and communication rooms, the management of fiber jumper information mainly relies on manual recording and maintenance. This method is not only inefficient, but also prone to errors. When the fiber jumper connection changes, the staff needs to manually update the relevant records, but in a large-scale network environment, it is difficult to ensure the timeliness and accuracy of the information. In addition, the existing fiber jumper management methods are insufficient in terms of information acquisition. There is a lack of effective real-time monitoring mechanism for the business information carried by the fiber jumper, such as business type and business code. Business identification information will change with the development, adjustment or upgrade of the business or network service, but traditional methods are difficult to capture these changes quickly. This makes it impossible for network managers to understand the actual use of the fiber jumper in time, and it is difficult to reasonably allocate and optimize network resources according to business needs. In terms of fiber jumper identification, although some fiber jumpers may use passive tags, these passive tags usually can only provide limited information and cannot be associated with the real-time business information of the fiber jumper. Passive tags cannot update key information such as the device port connected to the fiber jumper in real time, and their role is greatly reduced in the process of dynamic changes in the network. This makes it difficult to accurately distinguish different jumper fibers during network management, especially when a fault occurs, the problem jumper fiber cannot be quickly located, which prolongs the fault repair time and affects the normal operation of the network. In the process of information transmission in jumper fibers, the existing technology lacks a mechanism for dynamic adjustment according to the network environment. Different network environments have different requirements for the signals transmitted by jumper fibers, but the existing technology often adopts a fixed transmission mode and cannot adapt to the complex and changing network environment, thus affecting the quality and efficiency of jumper fiber information transmission. For the detection of optical signals in the jumper fiber transmission process, the existing photoelectric detectors usually use fixed working parameters, which makes it impossible for the photoelectric detector to detect optical signals in different situations well, and it is easy to have signal parsing errors or unable to parse, further reducing the reliability of jumper fiber information collection.

[0003] For example, the Chinese patent with the authorization announcement number CN117294353B discloses an automated mechanical fiber jumper control method based on intelligent management of optical fiber wiring, including: setting a passive RFID tag for each optical fiber jumper of each optical fiber device, and setting a corresponding RFID reader for the corresponding mechanical arm, controlling the preset ODF optical distribution frame to obtain the tag data collected by each RFID reader, and transmitting it to the preset intelligent wiring manager for data analysis, obtaining the real-time status corresponding to different optical fiber devices, establishing a basic optical fiber network in a preset area based on the real-time status, judging whether the total network coverage of the preset area is within the preset coverage range, and if not, controlling the preset intelligent wiring manager to adjust the position of the optical fiber jumper in each optical fiber device until the coverage of the basic optical fiber network is consistent with the preset coverage range. This patent establishes a regional automated basic optical fiber network, realizes the intelligent operation and maintenance of the optical communication network, and thus provides strong support for the communication network, but the RFID tags used can only provide limited information and cannot be associated with the real-time business information of the jumper.

Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative labor. Among them:

[0053] Figure 2 This is a structural schematic diagram of the intelligent fiber jumper automatic acquisition system based on wireless radio frequency and optical communication provided by the present invention. DETAILED DESCRIPTION

[0054] The technical solution of the present invention is described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present invention and the specific features in the embodiments are detailed descriptions of the technical solution of the present invention, rather than limitations on the technical solution of the present invention. The embodiments of the present invention and the technical features in the embodiments may be combined with each other unless there is a conflict.

[0055] Example 1

[0056] This embodiment introduces an intelligent fiber jumper automatic data collection device based on wireless radio frequency and optical communication. Figure 1 The device includes an information collection unit, a transmitting unit, a receiving unit, a radio frequency tag unit, and a data processing unit; wherein:

[0057] The information collection unit is used to collect service information and type of jumper fibers; the service information includes connection device information, device port information, and service identification information; the information collection unit is also used to collect associated environment data of jumper fibers;

[0058] Patch cables are optical cables used to connect different devices or network nodes. In data centers, communication rooms and other environments, patch cables are widely used to achieve physical connections between switches, routers, servers and other network devices. During network equipment upgrades, maintenance or network topology adjustments, the starting and ending ports of the patch cables and the connected devices may change, and passive tags cannot update this information in real time. The information collection units installed at both ends of the patch cables can detect the device ports connected to the patch cables in real time through optical communication. When the patch cable is connected to a new device port, the information collection unit can sense the changes in the access port of the optical signal, thereby updating the network link information in a timely manner.

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

[0060] The device port information includes the connection ports of the starting and ending points of the jumper, which is the key information for building the network topology. Accurately collecting the device port information of the jumper connection can clarify the flow direction and link relationship of the data in the network. The information collection unit can identify the connected device port information through optical communication combined with the port identification algorithm. For example, in a communication room, the information collection unit can identify that one end of the jumper is connected to a port of the switch and the other end is connected to the fiber optic network card port of the server, thereby building the accurate connection relationship of this part of the network link.

[0061] The service identification information includes the service type and service code carried by the jumper. The service identification information will change with the development, adjustment or upgrade of the service or network service. For example, a jumper originally used to carry the data transmission service of the office automation system within the enterprise may be adjusted to carry the video conferencing service at the same time after the enterprise business expands. The information collection unit can obtain the changes in the service identification information in a timely manner by means of optical communication through interaction with the network service management system or parsing the network configuration file, thereby accurately updating the service status associated with the jumper.

[0062] The transmitting unit dynamically selects a modulation mode based on the jump fiber type and the 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 to the receiving unit along the jump fiber;

[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 jump fiber; the modulation control subunit is configured with a modulation control strategy; the modulation control strategy includes dynamically selecting a modulation mode based on the jump fiber type and associated environmental data; the jump fiber type includes single-mode optical fiber and multi-mode optical fiber; the associated environmental data includes service light wavelength, ambient light intensity, and vibration interference intensity.

[0064] The modulation control strategy specifically includes:

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

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

[0067] ;

[0068] Single-mode optical fiber has the characteristics of low dispersion and low loss, small optical fiber core diameter, high signal transmission quality, high spectral efficiency, and can meet the high requirements of orthogonal amplitude modulation for signal transmission quality. Multimode optical fiber has large transmission capacity but has inter-mode dispersion, and the signal transmission quality is lower than that of single-mode optical fiber, so intensity modulation is preferred. An example of assigning a value to the optical fiber characteristic factor F based on the jumper type is as follows: if the jumper type is single-mode optical fiber, the value of F is 1; if the jumper type is multi-mode optical fiber, the value of F is 0.4;

[0069] The service optical wavelength is the wavelength of the optical signal emitted by the light source connected by the jumper. This optical signal is the basis for modulation. Short-wavelength optical signals have large attenuation and are more suitable for modulation methods that are insensitive to attenuation, such as intensity modulation. Long-wavelength optical signals have small attenuation and are suitable for modulation methods that are sensitive to dispersion but have high transmission rates, such as orthogonal amplitude modulation, which uses the low attenuation characteristics of long-wavelength light to achieve high-speed signal transmission. An example of assigning a value 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 interference in the environment where the patch cord is located, which may cause a certain degree of distortion when the patch cord 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 intensity, phase and other characteristics of the optical signal, while the frequency is less directly affected by light interference. In addition, environmental factors may cause vibration of the patch cord. For example, air conditioning blowing or accidental contact by people may cause mechanical vibration of the patch cord, which will also interfere with the transmission of the modulated signal. When these vibration disturbances exist, frequency modulation with high tolerance for signal distortion can also be selected. An example of assigning a value 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, and place its photosensitive probe at a location near the patch cord that may be interfered with. It can measure the power of light within a specific wavelength range (if the wavelength of the interference light is close to the wavelength of the service light, it will cause greater interference and require special attention) as the ambient light intensity. The greater the optical power of the interference 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 the accelerometer on the support structure of the jumper or on nearby objects 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 both light interference and vibration interference exist, the environmental disturbance factor E is 0.6. If only one of light interference and vibration interference exists, E is 0.3. If neither light interference nor vibration interference exists, E is 0.

[0071] The modulation control subunit is also configured with a first threshold value of the comprehensive disturbance index And the second threshold of the comprehensive disturbance index ; If the comprehensive disturbance index P is not less than , then the modulation mode selected by the modulation control subunit is quadrature amplitude modulation; if P is less than , and not less than , then 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] The first threshold of a comprehensive disturbance index With the second threshold The following is an example of the settings: The value is 1.8. The value is 1.2. Under this setting, when the jumper type is single-mode fiber, the service light 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 to meet the transmission requirements of quadrature amplitude modulation and give full play to its advantage of high spectrum utilization. When there is light disturbance or vibration disturbance, P will decrease, and anti-interference frequency modulation is selected. When multimode fiber is matched with a shorter service optical wavelength, regardless of whether there is light disturbance or vibration disturbance, P is less than , that is, select intensity modulation.

[0073] The modulator is located on the patch cord, and it modulates the optical signal passing through, that is, changes the parameters such as the intensity, frequency or phase of the light in a predetermined manner. The modulation process enables the optical signal to carry business information that can be decoded. Such a modulation mode selection strategy can make more flexible modulation decisions based on the properties of the patch cord itself and the various requirements of the environment in which it is located, so as to adapt to different application scenarios of patch cord automatic collection.

[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 a set bandwidth and bias voltage, and amplifies and filters the electrical signal for noise reduction based on a set gain coefficient;

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

[0077] During long-term use, patch cables may be affected by factors such as temperature and stress, which may cause changes in the transmission characteristics of optical signals. At the same time, patch cables for different business needs may use different modulation methods. If fixed photodetector working parameters are used, it may not be possible to detect optical signals transmitted by patch cables under different modulation modes and in 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 patch cables can be accurately parsed under different optical signal strengths and qualities, thereby ensuring the stability and accuracy of the entire device.

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

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

[0080] Extract the signal intensity of the optical signal and calculate the mean, recorded as ; The calibration subunit is configured with a signal strength threshold ;like Less than , then adjust the gain coefficient of the photodetector, 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 technicians in this field based on actual needs;

[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 strength of the electrical signal for subsequent signal processing. For example, when the jumper transmission distance is long, increasing the gain can make the weak signal reach the range that the subsequent demodulator can process.

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

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

[0086] ;

[0087] in, Indicates the rate of change of signal strength after the i-th sampling; Represents the signal strength obtained by the i-th sampling; represents the signal strength obtained by the i-1th sampling, where i is a positive integer greater than 1; The reference value representing the signal strength is set by those skilled in the art according to actual needs;

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

[0089] ;

[0090] in, represents the adjusted bias voltage after the i-th sampling; Represents the bias voltage after the i-1th sampling; is the adjustment coefficient of the bias voltage, is the initial bias voltage, which is set by technicians in this field based on actual needs.

[0091] The bias voltage can adjust the working point of the photodetector to keep it in the optimal linear working area. When the intensity range of the optical signal changes, such as when the optical signal intensity decreases due to fiber aging, adjusting the bias voltage can ensure that the photodetector can accurately convert the optical signal into an electrical signal to avoid signal distortion. Greater than 0, it means the signal strength is increasing; when Greater than the intensity change threshold , then increase the bias voltage to move the photodetector working point upward to avoid signal saturation; when Less than 0, indicating that the signal strength is decreasing; if Less than the negative intensity change threshold , then reduce the bias voltage to move the photodetector operating point downward to better detect weaker signals.

[0092] The adjusting the working parameters of the photodetector based on the adaptive calibration strategy also includes adjusting the bandwidth of the photodetector, as follows:

[0093] Set the frequency detection cycle of the optical signal; in each frequency detection cycle, let the sampling frequency be , let the number of sampling points be N, perform frequency domain transformation on the optical signal to obtain the spectrum of the optical signal; record the amplitude of the kth 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 ; Based on the high-frequency threshold, the spectrum of the optical signal is divided into high-frequency intervals, and the high-frequency intervals are specifically ;

[0095] The energy proportion of the high-frequency interval is calculated as follows:

[0096] ;

[0097] in, Indicates the energy proportion of the high-frequency range; Indicates the high frequency threshold The index in the spectrum; that is, the The frequency component corresponds to the high-frequency threshold ;

[0098] The calibration subunit also sets a high frequency ratio threshold and the maximum threshold of bandwidth ,like Greater than , then adjust the bandwidth of the photodetector, the formula is as follows:

[0099] ;

[0100] Wherein, B represents the adjusted bandwidth; is the bandwidth adjustment factor, is the initial bandwidth, which is set by technicians in this field based on actual needs; It means taking the largest item in the brackets.

[0101] The bandwidth determines the frequency range of the signal that the photodetector can effectively detect. In a network environment, if the frequency component of the signal changes (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 the high-frequency component of the detected signal increases, the bandwidth of the photodetector is appropriately widened to ensure that the signal can be fully detected. At the same time, set the upper limit of the bandwidth, that is, the maximum threshold of the bandwidth , avoiding the problem of excessive noise caused by over-expanding the bandwidth.

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

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

[0104] The main function of a passive tag is to store the unique identifier of a patch fiber. The unique identifier is a permanent serial number that remains unchanged throughout the life cycle of the patch fiber. It is the core information for accurately distinguishing and managing patch fibers, and is the identity credential of the patch fiber in the entire network resource management system. Regardless of how the position of the patch fiber changes in the network or how the device it is connected to is updated, this unique identifier can always be used to identify the patch fiber. Passive tags can also record some relatively fixed physical properties, such as fiber type information. Physical attribute information such as fiber type (single-mode or multi-mode) usually does not change after the patch fiber is manufactured, and different fiber types correspond to different uses. When reading a passive tag, the basic physical properties of the patch fiber can be quickly obtained without the need to determine the fiber type through complex optical detection every time.

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

[0106] The data processing unit includes a demodulator and a data integration subunit; wherein the demodulator is used to demodulate the electrical signal to obtain the service information of the corresponding jump fiber;

[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 detector to detect the change of frequency, converts the frequency change into a change of voltage or current, and then restores the original business information. For phase modulation, the demodulator uses coherent demodulation or differential coherent demodulation to demodulate the business 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 jumper fiber and send them to the cloud server; the method is as follows:

[0109] Communicate with the radio frequency reader to obtain the identification information of the jump fiber, and read the business information of the jump fiber demodulated by the demodulator; create a jump fiber information data packet; the jump fiber information data packet includes a business information field and an identification information field; in this data packet, the business information and the identification information are combined together in a certain format and distinguished by a specific separator or data structure so that the cloud server can accurately parse; send the jump fiber information data packet to the cloud server to complete the automatic collection of the jump fiber information.

Optionally, the cloud server can also use big data analysis technology to conduct in-depth mining and analysis of the stored data, such as analyzing the frequency of fiber jumper usage, business traffic trends, failure modes, etc., to provide data support for network optimization and decision-making.

[0117] The specific functions of the above modules are realized by referring to the relevant contents of the intelligent fiber jumper automatic acquisition device based on wireless radio frequency and optical communication described in Example 1, which will not be elaborated here.

[0118] Example 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 also configured with a second modulation control strategy; the second modulation control strategy controls the modulation mode of the modulator based on the network environment index; the network environment index includes a network delay index, a bandwidth utilization index, and a bit error rate index; the modulation control subunit is configured with a mapping table of service identification information and network environment index; the mapping table records the service identification information and the value of each network environment index corresponding to each service identification information; the second modulation control strategy is specifically as follows:

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

[0122] ;

[0123] Among them, S represents the comprehensive index of the network environment of the jump fiber; D represents the corresponding network delay index; U represents the corresponding bandwidth utilization index; e represents the corresponding bit error rate index; , , They are all weight coefficients, which are set by technicians in this field based on actual needs;

[0124] The modulation control subunit is also configured with a first threshold and a second threshold of the network environment comprehensive index; if S is less than , then set the modulation mode of the modulator to quadrature amplitude modulation; is the first threshold of the comprehensive index of the network environment; if S is greater than or equal to , then set the modulator's operating mode to intensity modulation.

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

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

[0127] If the bit error rate indicator e is not 0, the modulation mode of the modulator is set 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 jumper is located. For example, when the network traffic carried by the jumper is large and the transmission speed requirement is high, it automatically switches to a higher rate modulation method (such as switching from simple intensity modulation to high-order phase modulation); when the network environment is relatively stable but the signal quality requirement is higher, a more interference-resistant modulation method (such as frequency modulation) is used to select the best modulation method. Such a modulation mode selection strategy can make more flexible and reasonable modulation decisions based on the various requirements of the network to adapt to different application scenarios of jumper automation collection.

[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 the 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 the anti-interference ability is relatively weak because the light intensity is easily affected by external factors (such as fiber bending loss and interference from other light sources). And in the case of multi-user or high bandwidth requirements, the information transmission efficiency is limited. Frequency modulation (FM) enables the frequency of the optical signal to change according to the information to be transmitted, and has a strong anti-interference ability because the frequency is less susceptible to minor losses and interference during optical fiber transmission than the intensity. This modulation mode performs well in environments with high signal quality requirements, 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 higher data transmission rates and has advantages in high-speed communication networks, but the precise detection and recovery of the phase is technically complex and is sensitive to the dispersion and other characteristics of the optical fiber. Quadrature amplitude modulation (QAM) changes the amplitude and phase of the optical signal at the same time, mapping the information to multiple dimensions of the signal. For example, 16-QAM represents 16 different symbols through 4 amplitudes and 4 phase combinations. This modulation mode can transmit more information in the same bandwidth and has high spectrum utilization, but it has high requirements on 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, bandwidth utilization index, and bit error rate index respectively represent the tolerance of the network where the jumper is located to the network delay, bandwidth utilization, 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 bit error rate requirement for the jumper is extremely high, that is, the bit error rate is required to be as 0 as possible. The lower the bandwidth utilization index, the lower the tolerance for low bandwidth utilization, that is, high bandwidth utilization is required. The impact of the network delay index, bandwidth utilization index, and bit error rate index on the modulation mode is as follows: When the network delay index is low, that is, the network where the jumper is located has stricter requirements for network delay, the network needs to quickly transmit the jumper status and label information, and phase modulation (PM) or quadrature amplitude modulation (QAM) can be selected to increase the transmission rate. For example, in short-distance jumper communication within a data center, the delay requirement is extremely high, and phase modulation or quadrature amplitude modulation can transmit a large amount of jumper and label detail information in a short time. When the network delay index is low, such as some backup links with low real-time requirements, intensity modulation (IM) can be used. The modulation and demodulation process is simple and the cost is low. When the bandwidth utilization index is low, quadrature amplitude modulation is a good choice. If the jump fiber communication needs to transmit a large amount of information within a limited bandwidth, such as the detailed identity information of multiple passive tags and jump fiber performance parameters at the same time, the multi-dimensional information encoding method of QAM can meet the requirements. In scenarios where the bandwidth is relatively abundant and the 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 needs. When the bit error rate index is low, such as jump fiber communication in financial data transmission networks, frequency modulation or phase modulation is a better choice. Because of their strong anti-interference ability, they can effectively reduce the bit errors caused by factors such as optical fiber microbending and external light interference. For networks that can accept a certain bit error rate, such as some internal network monitoring links for non-critical businesses, intensity modulation can be used as an economical choice.

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

[0133] If the business type is financial transaction business, such as stock trading, electronic payment, etc., the corresponding network delay index is 0, because financial transactions require extremely low delays, and any delays may cause transaction price fluctuations or transaction failures; the bandwidth utilization index is 0. Although the amount of data in each transaction is not large, transactions are frequent, and high bandwidth utilization is required to ensure that a large amount of transaction information can be transmitted quickly; the bit error rate index is 0. 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 streaming service, such as high-definition video live broadcast or video on demand service, 4K / 8K online video playback, the corresponding network delay index is 0. For real-time live broadcast, too high a delay will affect the audience's viewing experience; for on-demand, although the delay requirement is slightly lower, smooth playback must also be guaranteed, so the overall delay requirement is relatively low; the bandwidth utilization index is 0. The amount of high-definition video data is huge, and high bandwidth utilization 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 amount of bit errors may only cause a brief mosaic or screen distortion on the video screen, which will have a certain impact on the overall experience, but compared with financial transactions, the requirements are slightly lower.

[0135] If the business type is enterprise office automation business, such as internal document sharing, email, office automation software, etc., the network delay index is 1. Compared with financial transactions and video services, office automation services are less sensitive to delays, and a slight delay in document transmission or email sending is usually acceptable. The bandwidth utilization index is 0.5. The data volume of documents and emails is average, but there are many users within the enterprise and they may use it at the same time, so a certain bandwidth utilization is required, but it is not an extremely high requirement. The bit error rate index is 0.5. Bit errors may cause document damage or email content errors, but enterprises usually have certain error correction and retransmission mechanisms, so the bit error rate requirements are not very stringent.

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

[0137] If S < 0.33, quadrature amplitude modulation (QAM) is preferred. This may be a scenario with high requirements for low latency and high bandwidth utilization. A lower QAM can meet the requirements of quickly transmitting a large amount of information under a better channel.

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

[0139] If S ≥ 0.66, select intensity modulation (IM). This usually corresponds to scenarios where bandwidth utilization and latency requirements are not high and cost is more sensitive. A low IM is sufficient to meet basic information transmission needs.
