Description

Pre-emphasis parameter configuration method and device

Technical field

The present application relates to, but is not limited to, the field of communication technologies, and in particular, to a method and an apparatus for configuring pre-emphasis parameters.

Background technique

Currently, devices located in the access network, the aggregation network, and the backbone network communicate with each other through optical/electrical interfaces. Therefore, as the first level of the packet entering the device and the last packet that the packet is forwarded after being processed by the device, the processing of the packet on the port greatly affects the quality of the communication. According to the ISO seven-layer network model, the physical layer "uses the physical medium to provide a physical connection for the data link layer to transparently transmit the bit stream", which encodes information into current pulses or other signals for transmission over the network, thus the physical layer ( The Physical Layer (PHY) device is the ultimate determinant of signal quality. As shown in FIG. 1, FIG. 1 is a typical MAC---PHY connection diagram. For transmitting packets, the message passes through the INT_PHY (physical layer device integrated into the MAC) and EXT_PHY (the physical layer not integrated into the MAC) in the TX direction. The device and the small form-factor pluggables (SFP), for receiving packets, the packets pass through the optical module, EXT_PHY and INT_PHY in the RX direction. In the path of the TX/RX bidirectional signal, the signal will be distorted, resulting in high signal-to-noise ratio in the low-frequency band at the receiving end and insufficient signal-to-noise ratio in the high-frequency band. The related technology usually uses pre-emphasis technology to solve this problem. The basic principle of pre-emphasis is to increase the high-frequency component of the input signal and then transmit it. A set of pre-emphasis parameters has two values: main/post and drive current (idriver), and setting the pre-emphasis parameter is essentially the combination of finding the best (main/post, idriver).

There are two main methods for pre-emphasis debugging of the current port sender: 1. Measure the optimal value of high-speed signal filtering; 2. Test the copy machine. However, although the first method can maximize the signal quality, the ambient temperature affects the quality of the signal transmission, and the optimal value cannot be screened. The method requires an oscilloscope and cannot cover all products. Sex; the second method cannot be automated, so it is less versatile.

The above content is only used to assist in understanding the technical solutions of the present application, and does not mean that the above content is related art.

Preferred embodiment of the invention

It is understood that the specific embodiments described herein are merely illustrative of the application and are not intended to be limiting.

The present application provides a method for configuring a pre-emphasis parameter. Referring to FIG. 2, in one embodiment, the method for configuring the pre-emphasis parameter includes:

Step S101, configuring multiple sets of initial pre-emphasis parameters and various preset ambient temperatures;

In this embodiment, multiple sets of initial pre-emphasis parameters are configured to detect or debug each set of pre-emphasis parameters, and an optimal pre-emphasis parameter is derived therefrom.

In this embodiment, considering the influence of the ambient temperature on the pre-emphasis parameter detection, a plurality of preset ambient temperatures are configured at the same time, so that the finally obtained pre-emphasis parameters can be adapted to different ambient temperatures to the greatest extent. Among them, in order to shorten the detection time, the preset ambient temperature is optionally low temperature, normal temperature and high temperature. Of course, this embodiment can also preset other temperatures, such as increasing the temperature gradient to increase the accuracy of the detection, so that the pre-emphasis parameters are detected in more ambient temperatures.

Step S102, in a preset first ambient temperature, for each set of initial pre-emphasis parameters, the specific code stream flows through a path with the INT integrated transceiver as the transmitting end or a path with the EXT integrated transceiver as the transmitting end. Error detection

In this embodiment, at a preset first ambient temperature, for example, under normal temperature conditions, for each set of initial pre-emphasis parameters, a specific code stream flows through a path with the INT integrated transceiver as a transmitting end or integrated with EXT. The transceiver is a path of the transmitting end and performs error detection, that is, error detection is performed for each path to filter at least one optimal pre-emphasis parameter in each path.

As shown in Figure 3, where INT PHY is the INT integrated transceiver and EXT PHY is the EXT integrated transceiver. There are five paths involved in the transmitting end, which are

paths

1, 2, 3, 4, and 5, respectively. Since

paths

4 and 5 are dependent on the characteristics of the SFP itself, and the optical module device does not provide related detection. Technical support, therefore, the path that ultimately involves the sender is

only path

1, 2, 3, where:

Path 1 is located on the transmit link, from the INT PHY to the EXT PHY, and the line side inner loop 7 is set in the EXT PHY to allow a specific code stream to flow, that is, the path 1 is: INT PHY==>1==>7==> EXT PHY;

Path 2 is located on the receiving link, EXT PHY cancels the line side inner ring, and after the specific code stream flows, from EXT PHY to INT PHY, that is, path 2 is: EXT PHY==>7==>2==>INT PHY ;

Path 3 is located on the transmit link and the receive link, starting from the EXT PHY, via line 3 to the optical module, the optical module uses the fiber self-loop, and the specific code stream flows through the fiber self-

loop lines

8 and 6, and returns to the EXT from the optical module. PHY, path 3 is: EXT PHY==>3==>5==>8==>6==>4==>EXT PHY.

In this embodiment, the specific code stream is optionally a Pseudo-Random Binary Sequence (PRBS) code stream, and of course, other code streams. The pseudo-random binary sequence code stream has self-verification characteristics, which can timely detect the occurrence of bit error on the link.

Step S103, after traversing the pre-emphasis parameter, determining that the specific code stream does not have an error pre-emphasis parameter when flowing through the path within a predetermined time;

In this embodiment, for each path, after traversing all the group pre-emphasis parameters at the first preset ambient temperature, the traversed pre-emphasis parameters may be formed into a matrix form, as shown in FIG. 4 , where In the main/post line, the drive current (idriver) is listed, wherein, for each group of pre-emphasis parameters, if a specific code stream flows through the above path and an error occurs within a predetermined time, the path is recorded. The corresponding detection result is 0. If no error occurs within a predetermined time when the specific code stream flows through the path, the corresponding detection result on the path is recorded as 1, so that the test is performed under normal temperature conditions as an example. Each path can obtain the error detection result in the form of a matrix as shown in FIG.

Wherein, in the matrix, the region with the detection result of 1 forms a closed region, and the corresponding pre-emphasis parameter of the region is an optional pre-emphasis parameter (it can be considered that the optional pre-emphasis parameter can better adapt to the normal temperature condition) The signal transmission), the area where the detection result is 0 forms an unclosed area, and the corresponding pre-emphasis parameter of the area is a non-selectable pre-emphasis parameter.

In this embodiment, after the error detection is performed at the first preset ambient temperature, the pre-emphasis parameter can be initially screened to detect the pre-emphasis corresponding to the region with the result of 1 (ie, no error occurs). The emphasis parameter is used as the initial pre-emphasis parameter for error detection at the next preset ambient temperature, which greatly reduces the number of pre-emphasis parameters for error detection at subsequent preset ambient temperatures.

Step S104: Perform error on the preset ambient temperature in which all error detection has been performed in a preset ambient temperature among the preset ambient temperatures in which the error detection is not performed. Each group of pre-emphasis parameters that have no error occurred during detection, and the specific code stream flows through the path with the INT integrated transceiver as the transmitting end or the path with the EXT integrated transceiver as the transmitting end, and error detection is performed until all Error detection is performed in the preset ambient temperature;

In this embodiment, in consideration of the influence of the environmental temperature factor, it is necessary to reset the ambient temperature and perform the test at a preset second ambient temperature, for example, under low temperature conditions.

In this embodiment, the pre-emphasis parameter that is not detected at the first ambient temperature is used as the initial pre-emphasis parameter detected at the second ambient temperature, and then, for each set of these pre-emphasis parameters, the specific The code stream flows through a path with the INT integrated transceiver as the transmitting end or a path with the EXT integrated transceiver as the transmitting end for error detection.

If an error occurs within a predetermined time when a specific code stream flows through the above path, the corresponding detection result on the path is recorded as 0, and if the specific code stream flows through the path, no error occurs within a predetermined time. Then, the corresponding detection result on the path is recorded as 1, so that the test is performed under low temperature conditions, and each path can obtain the error detection result in the matrix form as shown in FIG. 5.

In the matrix, the region with the detection result of 1 still forms a closed region, and the corresponding pre-emphasis parameter of the region is a pre-emphasis parameter for further error detection (it can be considered that the optional pre-emphasis parameter can better adapt to the normal temperature And the signal transmitted under low temperature conditions), the pre-emphasis parameter corresponding to the region where the detection result is 0 is a non-selectable pre-emphasis parameter.

It can be seen that in the matrix of FIG. 5, the closed region with the detection result of 1 is further reduced than the closed region shown in FIG. 4, that is, the closed region exhibits a convergent state, and the pre-emphasis parameters are further filtered.

In this embodiment, after the detection at the preset second ambient temperature, the pre-emphasis parameter that is detected at the preset second ambient temperature is not taken as the next preset ambient temperature (for example, a high temperature environment). The initial pre-emphasis parameter for detecting, for each set of these pre-emphasis parameters, the specific code stream flows through the path with the INT integrated transceiver as the transmitting end or the path with the EXT integrated transceiver as the transmitting end, and the error detection is performed. Error detection is performed until all preset ambient temperatures. Taking the test under high temperature as an example, each path can obtain the error detection result in the matrix form as shown in FIG. 6.

In this embodiment, the optional pre-emphasis parameters are tested at different ambient temperatures, so that the closed region converges continuously, and the pre-emphasis parameters are further filtered.

In step S105, after the error detection is performed at all preset ambient temperatures, the pre-emphasis parameter that does not have an error at all preset ambient temperatures is used as the pre-emphasis configuration value of the corresponding path.

In this embodiment, after the error detection is performed at all preset ambient temperatures, the pre-emphasis parameter corresponding to the error is not used as the pre-emphasis configuration value of the corresponding path at all preset ambient temperatures. It is believed that these pre-emphasis parameters are able to accommodate the superior transmission of the transmitter signal (high speed signal) at all detected ambient temperatures.

After the pre-emphasis parameter is configured on the network device, in actual applications, the drift usually occurs. In this embodiment, the pre-emphasis parameter of the pre-emphasis configuration value of the corresponding path is finally adapted to various ambient temperatures, so even When drift occurs, the quality of the signal transmission at the transmitting end can also be in a better range.

In addition, since the present embodiment performs error detection on the path involving the transmitting end, it is possible to accurately locate the link failure position.

Compared with the related art, the method for configuring the pre-emphasis parameter provided by the embodiment includes: flowing a specific code stream through the INT integrated transceiver for each set of initial pre-emphasis parameters at a preset first ambient temperature. For the path of the transmitting end or the path of the EXT integrated transceiver as the transmitting end, error detection is performed to initially filter the pre-emphasis parameter, and the pre-emphasis parameter that has not generated the error is used as the preset next error detection. The initial pre-emphasis parameters at ambient temperature are used for error detection to further screen out pre-emphasis parameters without error occurrence. When error detection is performed at all preset ambient temperatures, in all preset environments. The pre-emphasis parameter that does not have an error at the temperature is a parameter that can adapt to all the ambient temperature for error detection. The configuration method of the pre-emphasis parameter can realize the superior transmission of the signal at the transmitting end, and the process of detection is automated. It is faster to determine the preferred pre-emphasis parameters, and does not need to use other equipment, and has versatility.

In an alternative embodiment, as shown in FIG. 7, on the basis of the embodiment of FIG. 1 above, Step S102 includes:

Step S1021: Enable, at each preset initial pre-emphasis parameter, a generator and a detector of a specific code stream of the INT integrated transceiver, and enable the EXT integrated transceiver for each set of initial pre-emphasis parameters. Generator and detector of a particular code stream;

Step S1022, flowing the specific code stream through a path of the generator of the INT integrated transceiver as a path of the transmitting end or a generator of the EXT integrated transceiver as a path of the transmitting end, and performing error on the detector corresponding to the end point of the path. Detection.

In this embodiment, as shown in FIG. 3, a triangle represents a specific code stream generator, and a circle represents a specific code stream detector. At a preset first ambient temperature, for each set of initial pre-emphasis parameters, enable the generator and detector of the particular code stream of the INT integrated transceiver, and the generator that enables the specific code stream of the EXT integrated transceiver And a detector, such as for the path 1 described above, a generator that enables a particular bitstream of the INT PHY, a detector that enables a particular bitstream of the EXT PHY, causes a particular codestream to be transmitted from the generator to the detector, and is inspected The error detection is performed; for the path 2 described above, the generator of the specific code stream of the EXT PHY is enabled, the detector of the specific code stream of the INT PHY is enabled; for the path 3 described above, the specific code stream of the EXT PHY is enabled. Generator and detector.

In an optional embodiment, as shown in FIG. 8, based on the foregoing embodiment of FIG. 1, the foregoing step S102 may further include:

Step S1023, preset a step value of the pre-emphasis parameter;

Step S1024, at a preset first ambient temperature, with the step value being separated, and for each initial pre-emphasis parameter after the interval, the specific code stream flows through the path with the INT integrated transceiver as the transmitting end. Or use the EXT integrated transceiver as the path of the sender for error detection.

In this embodiment, instead of traversing the pre-emphasis parameters of all groups, a step value (X, Y) may be set, and the components between the two main pre-emphasis parameters (main/post, idrifer) are respectively different by X. And Y, then, with the step value as the interval, for each initial pre-emphasis parameter after the interval, the specific code stream flows through the path with the INT integrated transceiver as the transmitting end or the path with the EXT integrated transceiver as the transmitting end. For error detection.

As shown in Figure 4 to Figure 6, the main/post step value is 4/4, and the idriffer step value is 1, which In this way, the debugging time can be greatly shortened. In addition, the step value is set in the embodiment for debugging and can be applied to all ambient temperatures.

In an optional embodiment, as shown in FIG. 9, on the basis of the foregoing embodiment of FIG. 1, the foregoing step S105 includes:

Step S1051: After error detection is performed at all preset ambient temperatures, the configured plurality of initial pre-emphasis parameters are arranged in a matrix form;

Step S1052: Determine, in the geometric region formed by the determined pre-emphasis parameter in the matrix, a pre-emphasis parameter located at a center of the geometric region as a pre-emphasis configuration value of the corresponding path.

In this embodiment, more than one set of pre-emphasis parameters may have no error at all preset ambient temperatures, which can achieve better transmission of the signal at the transmitting end.

In this embodiment, if there are multiple sets of pre-emphasis parameters finally determined, the configured plurality of initial pre-emphasis parameters may be arranged in a matrix form, wherein main_post is used as the row, and the driving current idriver is used as the column. .

In the embodiment, the pre-emphasis parameters are arranged in the above-mentioned matrix manner, and the corresponding pre-emphasis parameters at the geometric center in the closed geometric region or the corresponding pre-emphasis parameters at the geometric center of the close region are used as the optimal pre-emphasis configuration of the corresponding path. Values may be one or more groups. As shown in FIG. 6, (main/post, iriditer)=(47/16, 10) at the close geometric center of the closed area is the optimal pre-emphasis configuration value of the corresponding path. Thus, when the pre-emphasis parameter drifts, the drift may be a pre-emphasis parameter in the closed geometric region or a pre-emphasis parameter in the vicinity of the closed geometric region, and these pre-emphasis parameters can still transmit the transmitter signal better.

Error detection is performed until all of the preset ambient temperatures are performed;

In this embodiment, the pre-emphasis parameter that does not generate an error when detected at the first ambient temperature is used as the initial pre-emphasis parameter detected at the second ambient temperature, and then, for each group of these pre-emphasis The parameter is used to perform error detection by flowing a specific code stream through a path with the INT integrated transceiver as the transmitting end or a path with the EXT integrated transceiver as the transmitting end.
