Detailed description of the invention
Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not used to limit
Determine the present invention.
The present invention provides the collocation method of a kind of pre-emphasis parameters, with reference to Fig. 2, in one embodiment, and should
The collocation method of pre-emphasis parameters includes:
Step S101, configuration organizes initial pre-emphasis parameters and multiple default ambient temperature；
In the present embodiment, configuration organizes initial pre-emphasis parameters, to carry out each group of pre-emphasis parameters
Detection or debugging, therefrom draw the pre-emphasis parameters of optimum.
The present embodiment considers the impact that pre-emphasis parameters is detected by ambient temperature, configures multiple default simultaneously
Ambient temperature, so that the pre-emphasis parameters finally drawn can farthest adapt to different environment temperature
Degree.Wherein, in order to shorten the time of detection, default ambient temperature is preferably low temperature, room temperature and height
Temperature.Certainly, the present embodiment can also preset other temperature, such as, increase thermograde to increase detection
Precision so that pre-emphasis parameters detects in more ambient temperature.
Step S102, at a temperature of default first environment, for each group of initial pre-emphasis parameters,
Specific code stream is flowed through the path with INT integrated transceiver as transmitting terminal or with EXT integrated transceiver is
The path of transmitting terminal, carries out Error detection；
In the present embodiment, at a temperature of default first environment, such as under normal temperature condition, for each
Organize initial pre-emphasis parameters, specific code stream is flowed through the path with INT integrated transceiver as transmitting terminal or
Path with EXT integrated transceiver as transmitting terminal, and carry out Error detection, i.e. each paths is all entered
Row Error detection, at least filters out one group of optimum pre-emphasis parameters realizing each paths.
As it is shown on figure 3, wherein, INT PHY is INT integrated transceiver, and EXT PHY is EXT collection
Become transceiver.The path relating to transmitting terminal has 5, is path 1,2,3,4,5 respectively, due to
The characteristic of optical module SFP self is depended in path 4 and 5, and optical module device does not provide relevant detection
Technical support, therefore, the path finally relating to transmitting terminal only has path 1,2,3, wherein:
Path 1 is positioned on transmission link, from INT PHY to EXT PHY, arranges line in EXT PHY
Trackside internal ring 7, makes specific code stream flow through, i.e. path 1 is: INT PHY==> 1==> 7==> EXT PHY；
Path 2 is positioned on reception link, and EXT PHY cancels line side internal ring, after specific code stream flows through,
From EXT PHY to INT PHY, i.e. path 2 is: EXT PHY==> 7==> 2==> INT PHY；
Path 3 is positioned at transmission link and receives on link, from the beginning of EXT PHY, and via line 3 to light

Block returns EXT PHY, i.e. path 3: EXT PHY==> 3==> 5==> 8==> 6==> 4==> EXT
PHY。
In the present embodiment, specific code stream is preferably pseudo-random binary sequence (Pseudo-Random
Binary Sequence, PRBS) code stream, naturally it is also possible to it is other code stream.Pseudo-random binary sequence
Row code stream has the characteristic of self-authentication, can the generation of error condition on the link of perception in time.
Step S103, after having traveled through described pre-emphasis parameters, obtains described specific code stream in the scheduled time
The pre-emphasis parameters of error code is there is not in inherence when flowing through described path；
In the present embodiment, for every paths, after traversal has detected all groups of pre-emphasis parameters, permissible
By the form of pre-emphasis parameters one matrix of composition after traversal, as shown in Figure 4, wherein, with main/post
For row, with drive electric current idriver for row, wherein, for each group of pre-emphasis parameters, if special code
There is error code when stream flows through an above-mentioned paths in the given time, then record correspondence on this paths
Testing result is 0, if there is not error code when specific code stream flows through this paths in the given time, then
Recording testing result corresponding on this paths is 1, so, as a example by testing under normal temperature condition,
The Error detection result of the available matrix form as shown in Figure 4 of every paths.
Wherein, in this matrix, testing result is the region of the region formation closing of 1, and this region is corresponding
Pre-emphasis parameters be that optional pre-emphasis parameters is (it is believed that this optional pre-emphasis parameters can be more preferable
Ground adapts to the transmission of signal under normal temperature condition), testing result be 0 region form the region do not closed, should
Pre-emphasis parameters corresponding to region is non-optional pre-emphasis parameters.
In the present embodiment, after first Error detection, it is possible to pre-emphasis parameters is carried out preliminary screening,
Detect using the pre-emphasis parameters that the region (error code does not i.e. occur) that testing result is 1 is corresponding as next round

Pre-emphasis parameters, is back to carry out the step of Error detection and circulate；
In the present embodiment, it is contemplated that the impact of ambient temperature factor, need to reset ambient temperature,
The second environment temperature preset is tested, and tests the most under cryogenic.
In the present embodiment, there is not, during detection, the pre-emphasis parameters that error code is corresponding at a temperature of first environment
As the initial pre-emphasis parameters of detection at a temperature of second environment, then, for each group, these are pre-
Increase the weight of parameter, specific code stream is flowed through the path with INT integrated transceiver as transmitting terminal or with EXT collection
Becoming transceiver is the path of transmitting terminal, carries out Error detection.
If there is error code when specific code stream flows through an above-mentioned paths in the given time, then record should
Testing result corresponding on paths is 0, if when specific code stream flows through this paths in the given time
Error code does not occurs, then recording testing result corresponding on this paths is 1, so, with under cryogenic conditions
As a example by testing, the Error detection result of the available matrix form as shown in Figure 5 of every paths.
Wherein, in this matrix, testing result be 1 region still form the region of closing, this region pair
The pre-emphasis parameters answered is that further alternative pre-emphasis parameters is (it is believed that this optional pre-emphasis parameters
The transmission of signal under room temperature and cryogenic conditions can be better adapted to), testing result be 0 region corresponding
Pre-emphasis parameters is non-optional pre-emphasis parameters.
It can be seen that in the matrix of Fig. 5, testing result is that the closed area of 1 is than the envelope shown in Fig. 4
Closed region reduces further, i.e. closed area presents the state of convergence, carries out pre-emphasis parameters further
Screening.
In the present embodiment, at a temperature of default second environment after detection, with at the second default ring
At a temperature of border, the pre-emphasis parameters corresponding when there is not error code of detection is as in next ambient temperature preset
The initial pre-emphasis parameters detected is carried out, for each group of these preemphasis under (such as hot environment)
Parameter, flows through the path with INT integrated transceiver as transmitting terminal or with the integrated receipts of EXT by specific code stream
Sending out device is the path of transmitting terminal, carries out Error detection, until having traveled through all of default ambient temperature.
As a example by testing under hot conditions, the error code of the available matrix form as shown in Figure 6 of every paths
Testing result.
The present embodiment is by testing optional pre-emphasis parameters under different ambient temperatures so that
Closed area is constantly restrained, and further screens pre-emphasis parameters.
Step S105, after having traveled through all default ambient temperatures, makees with acquired pre-emphasis parameters
Preemphasis Configuration Values for respective path.
In the present embodiment, after having traveled through all default ambient temperatures, obtain and finally error code pair does not occurs
The pre-emphasis parameters answered, using acquired pre-emphasis parameters as the preemphasis Configuration Values of respective path, can
To think, these pre-emphasis parameters can adapt to all transmitting terminal signal (height under the ambient temperature of detection
Speed signal) more excellent transmission.
After pre-emphasis parameters configures on network devices, in actual application, typically can drift about,
The pre-emphasis parameters that the present embodiment finally obtains, owing to can adapt to multiple ambient temperature, therefore, even if
Drift about, it is also possible to ensure that the quality of signal transmission of transmitting terminal is in more excellent scope.
Additionally, due to the present embodiment is that the path relating to transmitting terminal is carried out Error detection, therefore, it is possible to
For being accurately positioned link failure position.
Compared with prior art, the present embodiment is at a temperature of default first environment, initial for each group
Pre-emphasis parameters, specific code stream is flowed through the path with INT integrated transceiver as transmitting terminal or with EXT
Integrated transceiver is the path of transmitting terminal, carries out Error detection and realizes the Preliminary screening to pre-emphasis parameters,
And this is not occurred initial as at a temperature of default second environment of pre-emphasis parameters that error code is corresponding
Pre-emphasis parameters, then carry out Error detection so that the quantity of pre-emphasis parameters constantly reduces, further
Screening pre-emphasis parameters, after having traveled through all default ambient temperatures, does not finally occur error code corresponding
Pre-emphasis parameters is i.e. the parameter that can adapt to all ambient temperatures through detection, and it can realize transmitting terminal
The more excellent transmission of signal, the process automation excessively of detection, preferably pre-emphasis parameters can be got quickly,
And need not the equipment by other, there is versatility.
