[0024] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0025] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0026] In order to better understand the embodiments of the present application, the technical terms involved in the embodiments of the present application are explained as follows:

[0027] DWDM: Dense Wavelength Division Multiplexing, which transmits multiple optical signals of different wavelengths in the same optical fiber at the same time to increase the transmission capacity of the optical fiber.

[0028] ROADM: Reconfigurable Optical Add-Drop Multiplexer, which implements fast wavelength-level service scheduling and recovery at the optical layer to ensure network reliability and efficiency. The ROADM service switching principle is achieved through core technologies such as WSS (Wavelength Selective Switch) and advanced functions such as elastic grid. When a fault occurs, ROADM can automatically trigger service rerouting and recovery mechanisms to ensure network reliability and efficiency.

[0029] Calculation method of group and single-wavelength optical power in wavelength division system: Group optical power refers to the total optical power after multiple single-wavelength optical signals are combined (multiplexed) in the optical fiber. In the wavelength division system, when the power of each single-wavelength signal in the input combined signal is balanced, the group optical power (P combined wave) can be calculated by the following formula: P combined wave = P single wave + 10lgN (dBm).

[0030] Among them, P single wave represents the optical power of a single optical wavelength (in dBm), and N is the combined number of wavelengths (that is, the number of optical wavelengths transmitted simultaneously). This formula assumes that the power of all single-wavelength optical signals is the same, and does not take into account the loss in optical fiber transmission and the insertion loss of other optical devices.

[0031] OTU: Optical Transform Unit, which can perform 3R (Reshaping, Retiming, Regeneration) processing on any protocol service signal accessed from the client side, and then convert it into WDM (Wavelength Division Multiplexing) standard wavelength optical signal, so that subsequent wavelength division multiplexing units (such as wavelength combination / demultiplexing units) can perform wavelength division multiplexing processing on different optical signals.

[0032] VOA: Variable Optical Attenuator, mainly used for channel power balance, to achieve gain flatness, dynamic gain balance and transmission power balance.

[0033] When a link or node in a wavelength division system such as ROADM fails, ROADM can quickly switch services to ensure service continuity and reliability. ROADM equipment can dynamically schedule any wavelength through built-in wavelength selective switch (WSS) or other optical switch technologies. When a link failure is detected, ROADM can quickly switch services from the faulty wavelength to the backup wavelength.

[0034] After service switching, when the faulty link or node returns to normal, ROADM needs to perform service restoration operations to restore the service to the original transmission path. First, the ROADM and ASON control planes will continuously monitor the network status to evaluate whether the fault has been restored. Once the fault is confirmed to be restored, the system will decide whether to restore the service based on the preset strategy and priority.

[0035] ROADM achieves rapid switching and restoration of services through flexible wavelength and routing scheduling functions. During the service switching process, ROADM can quickly switch services from faulty links or nodes to backup resources, thereby reducing the number of service channels open on the faulty link; during the service restoration process, ROADM can restore services to the original transmission path based on network status and preset strategies, thereby increasing the number of service channels open on the link.

[0036] However, due to the business switching and restoration of the ROADM system, the wavelength division system will increase or decrease the number of working channels in use, and the change of working channels will cause the optical power of the wavelength division system group to change, which will increase the difficulty of judging whether the wavelength division system is normal. For example, after the optical cable is cut, the faulty link of the ROADM system has been restored, and the transmission maintenance personnel need to verify the service through the transmission equipment network management; however, the service will not be restored immediately. At this time, the working channels of the link are significantly reduced than before the cut, which will cause the optical power of the group to be significantly reduced. The maintenance personnel need to manually calculate the optical power of the group point by point to see if it is normal.

[0037] In order to solve the above problems, relevant solutions are provided in the embodiments of the present application, which are described in detail below.

[0038] According to an embodiment of the present application, a method embodiment of a method for determining the state of a wavelength division multiplexing system is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0039] The method embodiments provided in the embodiments of the present application can be used in Figure 1 The wavelength division system shown in the figure is implemented. Figure 1 As shown in FIG. 1 , the system includes a transmission equipment network management, an all-optical network intelligent operation base (Open Transmission Management System, OTMS) and a transmission integrated network management. The connection relationship between the transmission equipment network management, OTMS and the transmission integrated network management is as follows: Figure 1 shown.

[0040] In some embodiments of the present application, the transmission equipment network management can realize the centralized management of the transmission equipment, complete the functions of alarm, performance, configuration, fault handling, user management, information storage and backup management, and can be divided into primary transmission equipment network management and secondary transmission equipment network management. OTMS is a customer-oriented and business-oriented unified transmission network operation platform, which can not only meet the needs of customer experience and business development, but also meet the needs of network management operations for future transmission technology development. The transmission integrated network management is used to realize the centralized management of all transmission network elements and optical protection equipment in the region, and complete the alarm, performance, and configuration data collection work. And the wavelength division system status determination method provided in the embodiments of the present application is mainly implemented in the transmission integrated network management.

[0041] In some embodiments of the present application, the wavelength division system may be as follows: Figure 2 The connection relationship between the various communication devices in the wavelength division multiplexing (WDM) optical transmission system shown in FIG. Figure 2 Specifically, in order to standardize the optical interface parameters, the ITU-T G.692 document defines the following Figure 2 All reference points of the WDM optical transmission system shown in Figure 1. Tx1, Tx2, and TxN represent the terminal transmitters of the system. The transmitting end of the system uses a wavelength division multiplexer (combiner) to combine the signal optical carriers of different specified wavelengths and send them into one optical fiber for transmission. At the receiving end, a wavelength division multiplexer (demultiplexer) is used to separate the optical carriers of different wavelengths carrying different signals.

[0043] S1…Sn: reference point of channel 1…n on the optical fiber at the transmitter optical output connector;

[0044] RM1…RMn: reference points of channels 1…n on the optical fiber at the optical input connector of OM / OA;

[0045] MPI-S: Reference point on the optical fiber behind the optical output connector of the OM / OA;

[0046] S': reference point on the optical fiber behind the optical output connector of the line optical amplifier;

[0047] R': reference point on the optical fiber in front of the optical input connector of the line optical amplifier;

[0048] MPI-R: Reference point on the optical fiber in front of the optical input connector of the OA / OD;

[0049] SD1…SDn: are the reference points at the optical output connector of OA / OD;

[0050] R1…Rn: Reference points at the receiver optical input connector.

[0051] In the above operating environment, the embodiment of the present application provides a method for determining the state of a wavelength division system, such as Figure 3 As shown, the method comprises the following steps:

[0052] Step S302, the transmission integrated network management of the wavelength division system collects alarm information of multiple devices in the wavelength division system from the transmission equipment network management of the wavelength division system, wherein the transmission equipment network management is used to store the alarm information and performance information of multiple devices in the wavelength division system;

[0053] In the technical solution provided in step S302, the above alarm information includes the alarm information of the optical lines and OTU boards in the wavelength division system, including optical playback disks (PA, BA, LA) and optical monitoring disks (OSC). The specific disk names, alarm names, manufacturers, equipment models, etc. For example, the optical playback disk and optical monitoring disk of the device numbered OSN9600 of manufacturer A are named OAU and ST2 respectively; the optical playback disk and optical monitoring disk of the device numbered ZXONE9700 of manufacturer B are named EONA and SOSCB respectively; the optical playback disk and optical monitoring disk of the device numbered FONST5000 of manufacturer C are named PA, OA, and OSCAD respectively.

[0054] Step S304, the transmission integrated network management collects performance information of multiple devices in the wavelength division system from the transmission device network management;

[0055] In the technical solution provided in step S304, the performance information includes the line-side optical power of the optical disk in the wavelength division system, the optical power of the OUT board, bit errors and frequency deviation information. When collecting performance information, it can be obtained through each port. The port information of the port is related to the manufacturer and model of the transmission equipment. For example: for example, the OAU disk of the device numbered OSN9600 of manufacturer A needs to collect the optical power of the OAU-1 (IN) and OAU-4 (OUT) ports; the EONA disk of the ZXONE9700 device of manufacturer B needs to collect the optical power of the IN and OUT ports; the PA disk of the device numbered FONST5000 of manufacturer C needs to collect the optical power of the IN port, and the OA disk of the device numbered FONST5000 of manufacturer C needs to collect the optical power of the OUT port.

[0056] Step S306: after the number of working channels in the wavelength division system changes, determine whether the state of the wavelength division system is abnormal according to at least one of the alarm information and the performance information.

[0057] It should be noted that the specific reasons for the change in the number of working channels of the WDM system may be as follows:

[0058] The service switching of the OADM system will increase or decrease the number of working channels in use in the wavelength division system. When a link or node in the network fails, the ROADM will automatically trigger service rerouting according to the preset routing protection strategy (such as 1+1 protection, rerouting mechanism, etc.), switching the affected service wavelength from the faulty link to the backup link or redundant path, which will reduce the number of working channels in use in the wavelength division system of the faulty link; after the link failure is restored, the affected service wavelength will be switched back, which will increase the number of working channels in use in the wavelength division system of the link.

[0059] The expansion of the WDM system due to engineering construction will increase the number of working channels in use in the WDM system.

[0060] OTU disk failure and other reasons will reduce the number of working channels in use in the wavelength division system.

[0061] In the technical solution provided in step S306, the alarm information includes optical monitoring channel disk alarm information and optical line disk low light receiving alarm information, wherein the optical line disk low light receiving alarm information is used to indicate that the light receiving power of the optical line disk is lower than the preset light receiving power threshold; the step of determining whether the state of the wavelength division system is an abnormal state based on at least one of the alarm information and the performance information includes: when the optical monitoring channel disk alarm information or the optical line disk low light receiving alarm information is collected, determining that the wavelength division system is in an abnormal state, and the abnormal state is that the transmission system in the wavelength division system is interrupted; determining whether the working state of the equipment in the wavelength division system is abnormal based on the performance information, and when there is equipment in the wavelength division system whose working state is abnormal, determining that the state of the wavelength division system is an abnormal state.

[0062] Specifically, increasing or decreasing the working channels in use will not affect the OSC disk light reception, so it is possible to determine whether there is a WDM system interruption based on the OSC disk light reception alarm and optical power of the relevant station. If an OSC disk light reception loss alarm (such as OSC_LOS) or an optical line disk light reception low alarm (such as IN_POWER_LOW) is received, it can be determined that the transmission system is interrupted, otherwise it is determined that there is no transmission system interruption. The specific judgment process is as follows:

[0063] Begin:

[0064] Enter whether the OSC interruption alarm or the optical line tray low light alarm is received;

[0065] The IF receives an OSC interruption alarm or an optical line tray low light alarm;

[0066] THEN it is determined that there is a transmission system interruption;

[0067] ELSE determines that there is no transmission system interruption.

[0068] End

[0069] In some embodiments of the present application, the step of determining whether the working status of a device in a wavelength division system is abnormal based on performance information includes: determining a first received light power at a first moment and a second received light power at a second moment of an optical monitoring channel disk in the wavelength division system based on the performance information, wherein the first moment is a moment before the number of working channels in the wavelength division system changes, and the second moment is a moment after the number of working channels in the wavelength division system changes; determining the difference between the second received light power and the first received light power; and determining that the working status of the optical monitoring channel disk is an abnormal state when the absolute value of the difference is greater than a first preset threshold value.

[0070] Specifically, if the optical supervisory channel (OSC) receiving power of the relevant station decreases by more than 3dB, it can be determined that the OSC receiving power is reduced, which means that the OSC is abnormal, and then it is determined that the wavelength division system is abnormal. The specific judgment process is as follows:

[0071] Begin:

[0072] Input P_osc1 is the original first receiving light power of the OSC disk of the wavelength division system, and P_osc2 is the second receiving light power of the OSC disk after the wavelength division system increases or decreases the channel;

[0073] IF|P_osc2-P_osc1|≤3dB;

[0074] THEN judge that the OSC disk light is reduced;

[0075] ELSE: It is determined that the OSC disk receives light normally;

[0076] End

[0077] In some embodiments of the present application, the step of determining whether the working state of a device in a wavelength division system is abnormal based on performance information includes: determining a first optical power of a light-emitting disk in the wavelength division system at a first moment and a second optical power at a second moment based on the performance information, wherein the first moment is a moment before the number of working channels in the wavelength division system changes, and the second moment is a moment after the number of working channels in the wavelength division system changes; determining a preset optical power change value based on a change in the number of working channels in the wavelength division system; determining a first difference between the second optical power and the first optical power, and a second difference between the first difference and the preset optical power change value; and determining that the working state of the light-emitting disk is an abnormal state when the absolute value of the second difference is greater than a second preset threshold.

[0078] Specifically, it is possible to determine whether the luminous bottle is abnormal based on the change in the optical power of the luminous disk in the relevant station. Let N1 be the original number of channels in the wavelength division system; N2 be the number of channels after the wavelength division system increases or decreases the channels; P Δ is the expected optical power change of the luminous disc after adding or subtracting channels at the MPI-S point. Then:

[0079]

[0080] Then set is the original first optical power of the MPI-S spot light disk, The second optical power of the luminous disc after increasing or decreasing the channel for the MPI-S point will be and The difference and P Δ In comparison, if the phase difference is less than 0.5dB, that is If the optical power of the luminous disc is normal, it is considered that the optical power of the luminous disc is normal; otherwise, it is considered that the optical power of the luminous disc is abnormal. The specific judgment process is as follows:

[0081] Begin:

[0082] Input N1 is the original number of channels in the wavelength division system, N2 is the number of channels after the wavelength division system increases or decreases channels, P_ba1 is the original first optical power of the optical disc at the MPI-S point, and P_ba2 is the second optical power of the optical disc after the MPI-S point increases or decreases channels;

[0083] P_diff = 10*np.log(N2 / N1);

[0084] IF|(P_ba2-P_ba1)-P_diff|≤0.5dB;

[0085] THEN judge that the optical power of the luminous disk is normal;

[0086] ELSE: The optical power of the light-emitting disk is abnormal;

[0087] End

[0088] In some embodiments of the present application, the step of determining whether the working state of a device in a wavelength division system is abnormal based on performance information includes: determining whether the attenuation value of a variable optical attenuator in the wavelength division system has changed based on the performance information, wherein the variable optical attenuator is arranged in a receiving optical disk of the wavelength division system, or in a single variable optical attenuator disk of the wavelength division system; in the case where the attenuation value of the variable optical attenuator has changed, adjusting the attenuation value of the variable optical attenuator through a transmission equipment network management so that the attenuation value of the variable optical attenuator at a first moment and a second moment is consistent, wherein the first moment is a moment before the number of working channels in the wavelength division system changes, and the second moment is a moment after the attenuation value of the variable optical attenuator is adjusted; in the case where the attenuation value of the variable optical attenuator has not changed, or after the attenuation value of the variable optical attenuator is adjusted through the transmission equipment network management, determining whether the working state of the receiving optical disk in the wavelength division system is abnormal based on the performance information.

[0089] Specifically, the light receiving VOA may be set inside the light receiving device, or set on a separate VOA disk. Changes in the value of VOA will cause distortion of the optical power value of the light receiving disk, so it is necessary to determine whether the light receiving VOA of the relevant station has changed. If it has changed, the VOA needs to be adjusted to the original value, that is, the attenuation value of the variable optical attenuator needs to be adjusted through the transmission equipment network management so that the attenuation value of the variable optical attenuator at the first moment and the second moment is consistent. After that, it can be further determined whether the VOA of the light receiving disk has changed.

[0090] As an optional implementation, the step of determining whether the working state of a receiving optical disc in a wavelength division system is abnormal based on performance information includes: determining a third optical power of a light-emitting disc in the wavelength division system at a third moment and a fourth optical power at a fourth moment based on the performance information, wherein the third moment is a moment before the number of working channels in the wavelength division system changes, and the fourth moment is a moment after the number of working channels in the wavelength division system changes; determining a preset optical power change value based on the change in the number of working channels in the wavelength division system; determining a third difference between the fourth optical power and the third optical power, and a fourth difference between the third difference and the preset optical power change value; and determining that the working state of the light-emitting disc is an abnormal state when the absolute value of the fourth difference is greater than a fourth preset threshold.

[0091] Specifically, let N1 be the original number of channels in the wavelength division system; N2 be the number of channels after the wavelength division system adds or subtracts channels; let P Δ The expected optical power change value of the received optical disc after adding or subtracting channels at the MPI-R point is the preset optical power change value. Then:

[0092]

[0093] set up The original third optical power of the optical disc is collected by MPI-R. The fourth optical power of the optical disc after increasing or decreasing the channel for MPI-R point will be and The third difference and P Δ In comparison, if the phase difference is less than 0.5dB, that is If the optical power of the receiving disc is normal, it is considered that the optical power of the receiving disc is normal; otherwise, it is considered that the optical power of the receiving disc is abnormal. The specific judgment process is as follows:
