Detailed ways

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. It can be understood that the specific embodiments described here are only used to explain the relevant application, but not to limit the application. It should also be noted that, for convenience of description, only parts relevant to the relevant application are shown in the drawings.

my country's fixed broadband access network has basically become all-fiber, and access broadband continues to improve. At the current stage, 10G rate XG-PON has been deployed on a large scale, while the previous generation access network system GPON is still used to achieve smooth system evolution; therefore, a large number of Combo systems in which XG-PON and GPON coexist have emerged. Figure 1 shows the architecture of the Combo system Schematic diagram, as shown in Figure 1. On the optical network terminal (ONT) side, optical signals of different rates from GPON and XG-PON are coupled into the same trunk fiber through an optical splitter; due to the optical signals at the two rates Using different wavelengths, at the OLT receiving end, a multiplexer and demultiplexer can be used to separate the two rate signals and enter their respective detectors for photoelectric conversion and subsequent signal processing; at the same time, according to the standard, the GPON upstream wavelength range is 1290nm to 1310nm , the upstream wavelength range of XG-PON is 1260nm-1280nm, and the upstream wavelength range of 50G-PON in the future will have two intervals, which are exactly the upstream bands of GPON and XG-PON. Figure 2 is a schematic diagram of the upstream wavelength range of GPON and XG-PON. Figure 2 shows the upstream wavelength range of GPON and XG-PON.

Normally, in the upstream direction, GPON and XG-PON use wavelength division multiplexing to coexist without interference between each other. However, some XG-PON ONT lasers will produce high-power noise in the GPON band, Figure 3 A schematic diagram of the crosstalk problem, as shown in Figure 3. The laser of the XG-PON ONT produces high-power noise in the GPON band. Through spectral analysis, the spectrum of the XG-PON ONT on the right is obtained, which can be seen in the spectrum. , the XG-PON ONT has obvious bulging in the 1310nm band; although the Optical Signal Noise Ratio (OSNR) is as high as 44dB, due to the large noise bandwidth, its power cannot be ignored, and the 1310nm noise component will pass through the combined The demultiplexer enters the GPON receiver, thereby reducing the signal-to-noise ratio of the GPON signal; experimental results show that in extreme cases, the out-of-band (OOB) noise crosstalk may degrade GPON sensitivity by as much as 9.9dB.

However, when the above-mentioned crosstalk problem occurs, it may be reflected as a crack in the GPON bit error performance, which may be mistaken for a fault of the GPON transceiver module, but it is not actually a problem with the GPON channel; and, XG-PON ONT laser standard requirements The minimum OSNR is 30dB. Although the XG-PON ONT laser complies with the current ITU-T international standard, once other wavelength components are relatively large (the peak value is not high, but the spectrum range is very wide), it will enter the GPON channel receiver on the OLT side. , thus affecting GPON channel reception. Therefore, troubleshooting the two optical transceiver modules alone cannot detect these crosstalk problems in time. Therefore, how to effectively locate the crosstalk problems in the coexistence system is an issue that needs to be solved urgently.

In order to solve the problems existing in the crosstalk positioning method in the prior art, embodiments of the present application provide a crosstalk positioning method, a terminal, a processing system and a storage medium.

Furthermore, in the embodiments of the present application, the operation indicator information of the optical network terminal (ONT) can also be received; this is because under normal circumstances, the ONT can actually be equivalent to the ONU, which is a kind of equipment applied to the user end. Optical network equipment; but in a strict sense, ONT should be part of ONU; the difference between ONT and ONU is that ONT is an optical network terminal, directly located at the user end, while ONU is an optical network unit, and there may be other connections between it and the user. network, such as Ethernet.

The burst signal in the first ONU and the second ONU is in the uplink frame. The time position information specifically refers to the time position of the burst signal of each ONU in the first ONU and the second ONU in the 125us uplink frame of the respective channel.

It can also be understood that in the embodiment of the present application, the burst signal is a manifestation of packet loss in the ONU.

In the embodiment of this application, the terminal determines whether the ONU that has lost the packet meets the crosstalk triggering condition; in some embodiments of this application, if the received optical power of the ONU that has lost the packet is less than the anti-crosstalk received optical power threshold, it is determined that the packet has been lost. The ONU meets the crosstalk triggering conditions.

It should be noted that in the embodiment of this application, the anti-crosstalk receiving optical power threshold can be used to measure whether an ONU that has lost packets has the possibility of causing crosstalk. The size of the anti-crosstalk receiving optical power threshold is not specifically limited in this application.

For example, in the embodiment of the present application, the received optical power of the ONU that lost the packet is -26db, and the anti-crosstalk received optical power threshold is -24db, then it is determined that the ONU that lost the packet meets the crosstalk triggering condition.

Step 202: If the received optical power of the ONU that lost the packet is greater than or equal to the anti-crosstalk received optical power threshold, it is determined that the ONU that lost the packet does not meet the crosstalk triggering condition.

Further, in some embodiments of the present application, the spatio-temporal accompanying ONU corresponding to the packet-losing ONU can be determined based on the spatio-temporal accompanying information in the operation indicator information of the packet-losing ONU.

For example, in the embodiment of this application, the ONU that lost the packet is one of the first ONUs, then the ONU of the adjacent channel of the ONU that lost the packet is the second ONU; according to the operation indicators of the ONU that lost the packet The spatio-temporal accompanying information in the information can determine the phase difference information between the first ONU and the second ONU. Therefore, the time blocks of the first ONU and the second ONU can be aligned based on the phase difference information, and then the ONU that lost the packet can be The time position information of the burst signal in the 125us uplink frame in the operating indicator information can know the specific position of the burst signal in the uplink frame, so that in the aligned absolute time coordinate system, based on the burst signal in The position in the 125us uplink frame determines the corresponding ONU on the adjacent channel, that is, the adjacent channel ONU.

It should be noted that in the embodiment of the present application, the time slots and received optical power of the ONU can be reallocated based on dynamic bandwidth allocation, thereby solving the crosstalk problem that occurs.

In some embodiments of the present application, the method for the terminal to adjust the time slot of the ONU may be to adjust the time slot of the first ONU based on dynamic bandwidth allocation; or, to adjust the time slot of the second ONU based on dynamic bandwidth allocation. Perform adjustment processing; or, perform adjustment processing on the time slot of the first ONU and the time slot of the second ONU based on dynamic bandwidth allocation.

For example, in the embodiment of the present application, only the allocation of time slots by the DBA in the first PON to the hanging ONU can be changed, or only the allocation of the time slots by the DBA in the second PON to the hanging ONU can be changed, or both. Change the allocation of time slots by the DBA in the first PON to the connected ONU, and the allocation of time slots by the DBA in the second PON to the connected ONU.

Further, in the embodiment of the present application, the received optical power difference between the first ONU and the second ONU can also be adjusted to be less than or equal to the preset power difference threshold based on DBA.

It can be understood that in the embodiment of the present application, only the received optical power of the first ONU can be adjusted based on DBA, so that the received optical power difference between the first ONU and the second ONU is less than or equal to the preset power difference threshold. ; Or, only adjust the received optical power of the second ONU based on DBA, so that the received optical power difference between the first ONU and the second ONU is less than or equal to the preset power difference threshold; or, adjust the first ONU and the second ONU simultaneously based on DBA. The received optical power of the two ONUs is such that the received optical power difference between the first ONU and the second ONU is less than or equal to the preset power difference threshold.

Further, in the embodiment of the present application, the terminal adjusts the ONU's time slot and received optical power based on dynamic bandwidth allocation to solve the problem of crosstalk. After the crosstalk, there is no spatio-temporal companionship between the packet-losing ONU and the spatio-temporal companion ONU. , and the received optical power difference between the packet-losing ONU and the spatio-temporal accompanying ONU is less than or equal to the preset power difference threshold.

Further, in the embodiment of the present application, the method for the terminal to adjust the time slot of the ONU based on dynamic bandwidth allocation may include any one of the following steps:

Step 401: Adjust the time slot of the first ONU based on dynamic bandwidth allocation.

In the embodiment of the present application, the terminal adjusts the time slot of the ONU based on dynamic bandwidth allocation; in some embodiments of the present application, the terminal can adjust the time slot of the first ONU and the time slot of the second ONU based on dynamic bandwidth allocation. Make adjustments.

In addition, in the embodiment of the present application, after the crosstalk problem is processed for the ONU that has lost packets, and the crosstalk problem is solved, the terminal will continue to execute the process of receiving the operation indicator information of the ONU, so that it can continue to monitor whether new problems will occur. The ONU that lost packets, and whether the original ONU that lost packets will continue to lose packets; if packet loss does not occur in the future, it means that there is a power similar to out of band (OOB) to a large extent. The problem of excessive powerspectrum density (PSD) may cause crosstalk to adjacent channels in space and time with ONUs. Operations such as ONU replacement processing can be performed.

Further, in the embodiment of the present application, in the process of continuing to monitor and receive the operation indicator information of the ONU, if the ONU that has lost packets still loses packets, or other new ONUs that have lost packets occur, continue to follow the steps The above method is used for processing, including adjusting the time slot and receiving optical power of the ONU based on DBA. If the packet loss is solved, it means that the packet loss is caused by the crosstalk problem. If the packet loss is not solved, the above method can still be used. The processing method is continuously iterated to eliminate crosstalk problems.

To sum up, in the embodiments of the present application, a crosstalk positioning method is provided that can effectively locate the crosstalk problem in the Combo system and solve the crosstalk problem. Furthermore, it can only use the Combo system without replacing the network elements. The MAC layer of the system solves the crosstalk problem and improves terminal performance.
