Description

Technical Field

[0001] The present invention relates to the field of data processing technology, and in particular to an optical communication system design method, device, equipment and storage medium. Background Art

[0002] As the core infrastructure for information transmission, optical communication systems face stringent demands for long-distance transmission, high-speed bandwidth, and high reliability. Traditional electrical communication systems are limited by signal attenuation, electromagnetic interference, and bandwidth bottlenecks, and can no longer meet the capacity and performance requirements of modern communication networks. Optical communication, with its advantages of low loss, large bandwidth, and anti-interference, has become the mainstream transmission technology for backbone networks, metropolitan area networks, and access networks.

[0003] When optical signals are transmitted in optical fibers, energy attenuation occurs due to absorption and scattering of the optical fiber material, defects in the connection process, and bending deformation. During long-distance transmission, the signal power may drop below the sensitivity of the receiving end, resulting in data errors or transmission interruptions. In traditional solutions, the selection of optical amplifiers and the configuration of optical circuit boards are mostly based on the experience of engineers, lacking systematic optimization of multiple parameters such as gain, noise, and cost, which can easily lead to equipment redundancy or insufficient compensation. In addition, environmental factors such as temperature changes, humidity fluctuations, and mechanical stress can dynamically affect the optical fiber attenuation coefficient and equipment performance. Traditional static compensation solutions are difficult to cope with loss fluctuations in complex scenarios.

[0021] This application discloses a method for designing an optical communication system. For ease of understanding, the specific process of the embodiment of the present invention is described below. Figure 1 , an embodiment of the optical communication system design method in the embodiment of the present invention includes:

[0022] 101. Obtain design parameters of transmission equipment and optical cable;

[0023] In this embodiment, by systematically collecting multi-dimensional data, the comprehensiveness and accuracy of the design input are ensured, and the unreasonable final equipment layout plan caused by parameter omission is avoided.

[0024] 102. Calculate basic transmission loss based on the design parameters of the optical cable and use fuzzy logic algorithm to confirm the loss margin;

[0025] In this embodiment, a fuzzy logic algorithm is introduced to break through the limitations of traditional static margins, realize dynamic mapping of margins and environmental parameters, significantly improve compensation accuracy, and reduce insufficient or redundant signal attenuation caused by factors such as temperature changes.

[0026] 103. Calculate the optical compensation amount based on the basic transmission loss and the loss margin, and determine the type of optical amplifier based on the optical compensation amount and the design parameters of the transmission equipment;

[0027] In this embodiment, by quantifying the compensation requirements, insufficient gain or excessive amplification caused by traditional empirical selection is avoided, thereby improving the signal-to-noise ratio.

[0028] 104. Confirm the number of optical amplifiers and the specifications and quantity of optical circuit boards based on the confirmed types of optical amplifiers and optical compensation amounts;

[0029] 105. Generate a device layout plan based on the confirmed types and quantities of optical amplifiers and the confirmed specifications and quantities of optical circuit boards.

[0030] In this embodiment, a design method for optical communication systems that adapt to complex environments is constructed through a full-process closed loop of parameter quantification acquisition, loss dynamic modeling, intelligent device selection, and layout optimization design. This method realizes quantitative analysis of the entire chain from loss calculation to equipment layout, effectively avoiding performance redundancy or insufficiency that may result from relying on empirical design, thereby improving resource utilization.

[0031] The present application discloses a method for designing an optical communication system, which obtains design parameters of transmission equipment and optical cables; calculates basic transmission loss based on the design parameters of the optical cables, and uses a fuzzy logic algorithm to confirm the loss margin; calculates optical compensation based on the basic transmission loss and loss margin, and confirms the type of optical amplifier based on the calculated optical compensation and the design parameters of the transmission equipment, so as to further confirm the number of optical amplifiers and the specifications and number of optical circuit boards, thereby generating an equipment layout plan; the method disclosed in the present application uses a fuzzy logic algorithm to achieve dynamic confirmation of loss margin, which can significantly improve the compensation accuracy compared to traditional static compensation schemes, effectively solves the problem that traditional fixed margins cannot adapt to environmental changes, and ensures that the optical circuit boards configured based on the calculated optical compensation can meet the requirements of signal transmission.

[0032] Furthermore, in an embodiment of the present invention, obtaining the design parameters of the transmission equipment and the design parameters of the optical cable includes:

[0033] 201. Obtain equipment specifications, search the obtained equipment specifications to obtain design parameters of the transmission equipment, where the design parameters of the transmission equipment include transmitted optical power, receiving sensitivity, dynamic range, operating wavelength, dispersion tolerance, and service life;

[0034] In this embodiment, the transmitted optical power is the output power of the light source, which determines the initial energy intensity of the signal; the receiving sensitivity is the minimum optical power that the receiver can recognize, which affects the transmission distance limit; the dynamic range is the optical power range in which the receiver can operate normally, reflecting the anti-interference ability; the operating wavelength is the optical frequency band for signal transmission (such as 1310nm, 1550nm), which determines the selection of optical cables and devices; the service life is the expected life of the equipment, which is used for reliability and maintenance cycle assessment; by obtaining precise parameters, manual estimation errors are avoided and the accuracy of the design benchmark is ensured; the design parameters of the transmission equipment are key indicators covering the entire transmission link, providing complete input for subsequent loss calculations and device selection.

[0035] 202. Acquire communication requirements and working environment information, wherein the communication requirements include transmission distance, bandwidth, and transmission rate, and the working environment information includes ambient temperature fluctuation value;

[0036] In this embodiment, the transmission distance determines the length of the optical cable and the number of relay stations, and the bandwidth affects the selection of the optical cable type and the bandwidth of the optical device. The ambient temperature fluctuation value is used to evaluate the dynamic impact of temperature on the optical fiber attenuation coefficient and device performance, such as the change in bending loss caused by thermal expansion and contraction. In addition, the temperature fluctuation value serves as an input parameter of the fuzzy logic algorithm, providing an environmental variable for the dynamic loss margin calculation.

[0037] 203. Confirm design parameters of the optical cable based on communication requirements and working environment information, wherein the design parameters of the optical cable include the optical cable type, the attenuation coefficient corresponding to the optical cable type, the bending radius, the number of fusion points, and the number of active connectors;

[0038] In this embodiment, the type of optical cable can be determined based on the transmission distance. For example, single-mode optical cable is selected for long-distance, high-speed scenarios, and multi-mode optical cable is selected for short-distance scenarios. The attenuation coefficient is an inherent property of different types of optical cables and is directly related to the loss during signal transmission. The number of fusion points is determined by the length of the optical cable segments. The number of fusion points varies with the segment length. The bending radius is set according to the laying environment. Different laying environments, such as indoors, outdoors, in pipelines, etc., have different requirements on the degree of bending that the optical cable can withstand. The active connector is an optical cable distribution frame interface, which is determined by the number of distribution frames connected to the optical cable.

[0039] In this embodiment, the confirmed design parameters of the optical cable also include the cutoff wavelength, core diameter, cable diameter and dispersion corresponding to the optical cable type; among them, the cutoff wavelength is used to ensure that the optical cable is single-mode transmission at the operating wavelength to avoid multimode dispersion; the core diameter affects the optical signal coupling efficiency and transmission bandwidth, and is directly related to the effect and performance of optical signal transmission; the cable diameter determines the laying space and mechanical protection capability; the dispersion is used to evaluate the degree of pulse broadening during high-speed signal transmission and needs to match the dispersion tolerance of the transmission equipment.

[0040] Furthermore, in an embodiment of the present invention, the calculation of the basic transmission loss based on the design parameters of the optical cable includes:

[0041] 301. Calculate the optical cable attenuation loss based on the attenuation coefficient and transmission distance;

[0042] In this embodiment, optical cable attenuation loss (dB) = attenuation coefficient (dB / km) × transmission distance (km). By quantifying the inherent loss of optical fiber material as the main component of basic transmission loss, basic data is provided for subsequent compensation calculations.

[0043] 302. Calculate the connection loss based on the number of splice points;

[0044] In this embodiment, connection loss (dB) = number of splices × average loss per splice. The loss per splice is typically 0.1-0.3 dB. By separating process loss from material loss, it is easier to assess the impact of construction quality on system performance, providing a basis for process optimization.

[0045] 303. Calculate bending loss based on bending radius;

[0046] In this embodiment, during the installation of the optical cable, if the bending radius is lower than the specified minimum value, additional signal loss will occur. Taking the G.652 standard optical cable as an example, when the bending radius is ≤ 20 mm, the bending loss at each location is calculated according to the empirical formula. dB, meaning each bend causes approximately 0.1 dB of loss. In the empirical formula, parameter R is the actual bending radius (mm), and the coefficient 0.1 and reference radius 20 mm are derived from the mechanical performance indicators specified in the G.652 optical fiber standard, combined with the test method for bending loss in the IEC60793-2-50 standard to ensure compatibility with existing technical specifications. In actual engineering, if 10 such bends occur, the total loss will accumulate to 1 dB. Therefore, during the design phase, the loss caused by the laying process should be taken into consideration to prevent insufficient compensation due to improper construction, thereby ensuring the practicality and reliability of the design.

[0047] 304. Calculate active connector loss based on the number of active connectors;

[0048] In this embodiment, active connector loss (dB) = number of connectors × single connector loss, where single connector loss is typically 0.5 dB. By clearly defining the loss contribution of the interface device and distinguishing it from the splice loss, it is easier to select a high-reliability connector.

[0049] 305. Calculate basic transmission loss based on optical cable attenuation loss, connection loss, bending loss and active connector loss;

[0050] In this embodiment, basic transmission loss = optical cable attenuation loss + connection loss + bending loss + active connector loss. By integrating multi-source losses, a fixed loss value is formed in the absence of environmental interference, providing a benchmark for dynamic margin calculation and ensuring that the calculated optical compensation amount does not miss basic requirements.

[0051] Furthermore, in an embodiment of the present invention, the use of a fuzzy logic algorithm to determine the loss margin includes:

[0052] 401. Obtain a historical number of failures based on design parameters and working environment information of the transmission equipment, and obtain a reliability correction factor based on the historical number of failures;

[0053] In this embodiment, in order to ensure the reliability of the transmission equipment, a detailed analysis of historical operating data can be performed, including statistics on the number of failures and bit error rate violations; a mapping relationship table is pre-established to obtain a reliability weight factor corresponding to the number of failures; for example, when the number of failures is ≤5, the reliability weight factor is set to 1; when the number of failures is 5-10, the reliability weight factor is set to 1.2; when the number of failures is >10, the reliability weight factor is set to 1.5; by incorporating historical operating data into the loss margin calculation, data-driven reliability optimization can be achieved, thereby avoiding overly conservative or overly radical designs that may result from relying solely on theoretical parameters.

[0054] 402. Based on the ambient temperature fluctuation value, service life and reliability correction factor, a pre-built 7×7 rule matrix and fuzzy logic algorithm are used to perform preliminary calculations to obtain fuzzy results;

[0055] In this embodiment, a 7×7 rule matrix is ​​pre-constructed, which contains 49 fuzzy logic rules for processing the evaluation of equipment loss margin. For example, if the temperature fluctuation of the equipment is large and the service life is long, it is recommended to increase the loss margin. The input parameters, including ambient temperature fluctuation, service life and reliability correction factor, are converted into corresponding fuzzy sets through membership functions (for example, the membership corresponding to "high" temperature fluctuation is 0.8). After calculation and processing of the rule matrix, a fuzzy result is finally output, such as "medium-high" margin. By converting nonlinear factors into quantitative margins, the one-size-fits-all problem of traditional static margins is solved.

[0056] 403. Defuzzify the fuzzy result using a weighted average method to obtain a loss margin;

[0057] In this embodiment, a weighted average is performed on the membership functions within the fuzzy results (e.g., the "medium-high" interval) and converted into specific numerical values ​​(e.g., the "medium-high" interval is defuzzified to 5.2 dB). By converting the qualitative analysis of fuzzy logic into quantitative results, parameter configuration (e.g., optical amplifier gain setting) during engineering implementation is facilitated, thereby improving the operability of the design.

[0058] Furthermore, in an embodiment of the present invention, calculating the optical compensation amount based on the basic transmission loss and the loss margin, and determining the type of the optical amplifier based on the optical compensation amount and design parameters of the transmission equipment, includes:

[0059] 501. Calculate the sum of the basic transmission loss and the loss margin to obtain the optical compensation amount;

[0060] In this embodiment, the optical compensation amount (dB) = basic transmission loss + loss margin. By clarifying the required total gain of the system, that is, the optical compensation amount, a direct basis is provided for selecting the optical amplifier, ensuring that the signal power after transmission is still higher than the receiver sensitivity.

[0061] 502. Determine the gain range of the optical amplifier based on the optical compensation amount, determine the bandwidth range of the optical amplifier based on the operating wavelength, and determine the output power range of the optical amplifier based on the transmitted optical power;

[0062] 503. Determine the type of the optical amplifier based on the determined gain range, bandwidth range, and output power range;

[0063] In this embodiment, when selecting an optical amplifier, it is necessary to ensure that it meets the following multi-dimensional technical requirements to ensure the overall performance and stability of the system:

[0064] 1. Gain range: The gain of the optical amplifier must be greater than or equal to the required optical compensation to ensure that the signal strength is properly enhanced during transmission;

[0065] 2. Bandwidth range: The operating wavelength of the amplifier must match its effective bandwidth to ensure that the amplifier can effectively process signals of a specific wavelength and avoid signal distortion or loss caused by insufficient bandwidth;

[0066] 3. Output power range: The maximum output power of the amplifier must be less than or equal to the upper limit of the optical power transmitted by the transmission equipment to prevent excessive output power from damaging the transmission equipment or affecting signal quality;

[0067] By constraining amplifier selection in multiple dimensions, we can avoid the mismatch problem caused by selecting amplifiers based on only a single parameter, thereby improving the compatibility of devices and the stability of the entire optical communication system.

[0068] Furthermore, in an embodiment of the present invention, the determining the number of optical amplifiers and the specifications and number of optical circuit boards based on the determined types of optical amplifiers and optical compensation amounts includes:

[0069] 601. Obtain an optical amplifier gain based on the confirmed type of the optical amplifier;

[0070] In this embodiment, the single-stage maximum gain is extracted from the amplifier specification as the optical amplifier gain to clarify the single-stage compensation capability of the optical amplifier, provide basic data for cascade calculation, and ensure the accuracy of the calculation of the number of optical circuit boards.

[0071] 602. Obtain the number of optical amplifiers and the number of optical circuit boards by rounding up the ratio of the optical compensation amount to the optical amplifier gain, wherein the optical amplifiers correspond to the optical circuit boards in a one-to-one manner.

[0072] In this embodiment, the number of optical circuit boards = / For example, if the optical compensation is 21.2dB and the single-stage gain is 20dB, the number of optical circuit boards is / =2 pieces, and the number of optical amplifiers = the number of optical circuit boards; by rounding up, it is ensured that the cascade gain ≥ the optical compensation amount to avoid insufficient compensation due to rounding off, reflecting the conservative principle of design, that is, the principle of giving priority to ensuring performance.

[0073] 603. Confirm the specifications of the optical circuit board based on communication requirements and optical amplifier gain;

[0074] In this embodiment, the specifications of the optical circuit board should be compatible with the gain, bandwidth, and system transmission requirements of the optical amplifier. For example, in terms of gain processing capability, a single optical circuit board should be able to provide at least 20 dB of gain compensation to ensure that it matches the gain of an erbium-doped fiber amplifier (EDFA). In terms of bandwidth compatibility, the operating bandwidth of the optical circuit board should cover the 1530 to 1565 nm band to be consistent with the bandwidth of the erbium-doped fiber amplifier (EDFA). In terms of interface type, it should match the core diameter of the optical cable (for example, single-mode optical fiber corresponds to an LC interface) and meet the transmission rate requirement of 10 Gbps.

[0075] Furthermore, in an embodiment of the present invention, generating a device layout plan based on the confirmed types and quantities of optical amplifiers and the confirmed specifications and quantities of optical circuit boards includes:

[0076] 701. Obtain constraint requirements, where the constraint requirements include physical spacing requirements between adjacent communication devices, signal transmission path requirements, and regional temperature gradient requirements;

[0077] In this embodiment, the physical spacing requirement is that the optical amplifier and the circuit board are deployed adjacent to each other, with a distance between the two less than 0.5m, so as to reduce the loss of the optical fiber jumper; the signal transmission path requirement is a unidirectional flow design of the transmitting end, amplifier, optical circuit board, and receiving end to reduce the probability of signal crosstalk; the regional temperature gradient requirement can be that the temperature gradient caused by the concentration of heat sources is greater than 5°C / m, so that the equipment layout can avoid local overheating; by clarifying the space limitations in the project implementation, the functional requirements are combined with the feasibility of the project to improve the feasibility of the layout plan.

[0078] 702. Construct a layout space constraint model based on the design parameters of the transmission equipment, the design parameters of the optical cable, the type and quantity of the optical amplifiers, the specifications and quantity of the optical circuit boards, and the constraint requirements;

[0079] In this embodiment, the transmission equipment size, optical cable length, type and number of optical amplifiers, specifications and number of optical circuit boards, and constraint requirements are converted into a mathematical model, that is, the complex layout problem is abstracted into a computable mathematical model to provide input for the intelligent optimization algorithm, avoiding the subjectivity and inefficiency of manual layout.

[0080] 703. Using the particle swarm optimization algorithm, with minimizing the connection distance between devices and minimizing the regional temperature gradient as the objective function, the constructed layout space constraint model is solved to obtain the equipment layout plan;

[0081] In this embodiment, minimizing the connection distance between devices can reduce the amount of optical cables and signal delay; minimizing the regional temperature gradient can balance the temperature distribution; and the particle swarm optimization algorithm simulates the foraging behavior of bird flocks and searches for the optimal solution by iteratively adjusting the speed and position of particles (device positions).

[0082] In this embodiment, the particle swarm optimization algorithm is combined with the layout space constraint model to quantify the optimization target, achieve the objective optimal solution of the layout scheme, reduce cable costs, improve heat dissipation efficiency, and extend equipment life. This method is suitable for large-scale equipment layout scenarios, can significantly improve design efficiency, and reduce manual debugging time.
