Referring to Fig. 3, in one exemplary embodiment, a kind of optical module power consumption control method is applied to Fig. 2 implementation environments
Shown in optical module 100, this kind of optical module power consumption control method can perform by optical module 100, can include following step
Suddenly：
Step 210, the data traffic of monitoring host computer.
In order to be effectively controlled to optical module power consumption, in the present embodiment, control is used as using the data traffic of main frame
The foundation of optical module power consumption processed, i.e., if the data traffic of main frame is changed, then follow-up power consumption control is performed for optical module
Process processed.
Thus, judge whether to need to be controlled optical module power consumption by the monitoring to host data flow.
The data traffic monitoring of main frame can directly perform or set up data traffic prison by micro-control unit
Unit is controlled to perform, is not defined herein.
For example, as shown in figure 4, the data traffic monitoring unit 190 is connected to main frame 180 and transmitting clock data is extensive
Between multiple unit 120, reception clock data recovery unit 140, and it is connected with the electric signal of micro-control unit 110.On this basis,
The data traffic monitoring unit 190 just can be monitored to the data traffic of main frame 180, and the data traffic monitored is anti-
Micro-control unit 110 is fed to, to perform follow-up optical module power consumption control process by micro-control unit 110.
Further, can be the message transmission rate of monitoring host computer in the data traffic monitoring of main frame, data transfer is fast
It is larger that rate height is then considered as data traffic, can also be by data transfer packet loss implementing monitoring, for example, working as data transfer packet loss
It is larger, then it is larger to be considered as data traffic.
Further, the message transmission rate of main frame can be by reading in the data transmission interface chip that is configured in main frame
Take.
By being arranged such, the foundation using the data traffic of main frame as optical module power consumption control, after effectively having ensured
The accuracy of continuous optical module power consumption control.
Step 230, corresponding power consumption control is generated according to the data traffic monitored to instruct.
Wherein, power consumption control instructs the default reducing power consumption pattern for indicating optical module.
Default reducing power consumption pattern can be pre-set according to corresponding data traffic standard, the data traffic standard pin
For the data traffic of main frame, i.e. mark off several data traffic standards according to the different data traffic of main frame, then basis
Several data traffic standards correspondingly set several default reducing power consumption patterns.
For example, data traffic standard is divided into five：During operating at full capacity on the basis of the data traffic of main frame
Data traffic, data traffic standard one are higher than reference data flow 90% for the data traffic of main frame, and data traffic standard two is
The data traffic of main frame reaches reference data flow 70%~90%, and data traffic standard three reaches base for the data traffic of main frame
Quasi- data traffic 50%~70%, data traffic standard four for main frame data traffic reach reference data flow 30%~
50%, data traffic standard five is less than reference data flow 30% for the data traffic of main frame.
Correspondingly, default reducing power consumption pattern accordingly is set according to the data traffic standard of division.For example, five default drops
Power consumption mode includes four reducing power consumption patterns and a normal mode of operation, with respectively with a pair of five data flow standards 1
Should.Wherein, one corresponding normal mode of operation of data traffic standard, the corresponding reducing power consumption pattern one of data traffic standard two, data flow
The corresponding reducing power consumption pattern two of amount standard three, by that analogy.
On this basis, affiliated data traffic standard is just capable of determining that according to the data traffic monitored, and with this
Default reducing power consumption pattern corresponding to determining, and then generate the power consumption control instruction that may be used to indicate the default reducing power consumption pattern.
Or default reducing power consumption pattern can also be according to optical module electric current, speed and clock and data recovery list
Member working condition in any one, two kinds or three kinds could be adjusted to divide.
For example, default reducing power consumption pattern includes first kind reducing power consumption pattern, the second class reducing power consumption pattern and the 3rd class drop work(
Consumption pattern.
Wherein, first kind reducing power consumption pattern, in optical module electric current, speed, the working condition of clock data recovery unit
Any one needs to adjust.For example, the electric current of optical module is reduced, and the work of optical module speed and clock data recovery unit
State then keeps constant.
Second class reducing power consumption pattern, then refer to adjust optical module electric current, speed, the working condition of clock data recovery unit
In any two kinds.For example, optical module electric current is reduced, and by the working condition of clock data recovery unit by normal operating conditions
Stop working state is switched to, and keeps optical module speed constant.Or optical module electric current and speed are reduced, and clock data
The working condition of recovery unit keeps constant.
3rd class reducing power consumption pattern, refers to the working condition of optical module electric current, speed and clock data recovery unit all
Need to be adjusted, that is, reduce the electric current and speed of the optical module, and by the working condition of the clock data recovery unit
Stop working state is switched to by normal operating conditions.
In other words, optical module lower power consumption is less in first and second class reducing power consumption pattern, suitable for host data flow compared with
Big situation, and optical module lower power consumption is more in the 3rd class reducing power consumption pattern, suitable for monitoring less host data stream
Amount.
By the setting for presetting reducing power consumption pattern so that optical module lower power consumption can be with the change of host data flow
And adjust in real time, it ensure that the flexibility of optical module lower power consumption.
Step 250, optical module is controlled to enter the default reducing power consumption pattern of power consumption control instruction instruction.
Firstly the need of explanation, default reducing power consumption pattern refer to for the predetermined current set by optical module, scheduled rate,
Clock data recovery unit default operating condition etc..Wherein, clock data recovery unit default operating condition includes normal work
Make state and stop working state, normal operating conditions refers to launch clock data recovery unit and/or reception clock data is extensive
Multiple unit normal work, stop working state refer to launch clock data recovery unit and/or receive clock data recovery unit
Do not work.
Further, predetermined current includes default bias current and default modulation electric current, and scheduled rate includes default transmitting
Speed and default receiving velocity.
Secondly, the predetermined current in the default reducing power consumption pattern of difference, scheduled rate, clock data recovery unit preset work
State etc. is different.
On this basis, when optical module enters some default reducing power consumption pattern, that is, refer to that optical module is a certain according to this
Predetermined current, scheduled rate, clock data recovery unit default operating condition in individual default reducing power consumption pattern etc. are run, with
This reaches the purpose of control optical module power consumption.
In other words, to the control of optical module power consumption, electric current, speed, clock number when substantially being run to optical module
The adjustment of working condition according to recovery unit etc..
Further, electric current includes bias current and modulation electric current, and speed includes emission rate and receiving velocity, clock number
Include transmitting clock data recovery unit according to recovery unit and receive clock data recovery unit.
As shown in figure 5, in a specific embodiment, pass through the host data flow that feedback monitoring arrives to microcontroller list
Member, so that the default reducing power consumption pattern that micro-control unit enters according to required for the data traffic judges optical module, and generate phase
The power consumption control instruction answered, and then enter different default reducing power consumption moulds according to the instruction control optical module of power consumption control instruction
Formula.Wherein, presetting reducing power consumption pattern includes normal mode of operation, reducing power consumption pattern one, reducing power consumption pattern two, reducing power consumption pattern
3rd, reducing power consumption pattern four.For example, when data traffic 50%~70% on the basis of the data traffic of main frame, control optical module enters
Enter reducing power consumption pattern two, when the data traffic of main frame is higher than reference data flow 90%, control optical module enters normal work
Pattern.
By process as described above, realize automatically controlling for optical module power consumption, i.e., can be according to host data flow
Change, dynamically adjust the default reducing power consumption pattern entered required for optical module, and then dynamic when adjusting optical module operation
Electric current, speed, in the working condition of clock data recovery unit any one, two kinds or three kinds, so as to effectively drop
The power consumption of low optical module, especially when the data traffic of main frame is smaller, extend the life-span of optical module with this.
In one exemplary embodiment, before step 230, method as described above can also comprise the following steps：
Treat on optical module electric, cited sb. for meritorious service the unlatching that consumption automatically controls in optical module acceptance of the bid.
The mark that power consumption automatically controls is configured with optical module, the mark acceptance of the bid automatically controlled by the power consumption cites sb. for meritorious service consumption certainly
The unlatching of dynamic control, you can open optical module and automatically controlled to power consumption.
For example, the mark automatically controlled in the form of register as power consumption, correspondingly, the numerical value of register then marked
The opening and closing that power consumption automatically controls.When the numerical value of register is 1, the unlatching that automatically controls of mark power consumption.Certainly, register
Numerical value can according to reality use need neatly to adjust.
Further, optical module acceptance of the bid is cited sb. for meritorious service the unlatching that automatically controls of consumption, can perform when electric on optical module, also may be used
Be optical module monitor for the first time main frame data traffic be less than 90% when perform.
When opening power consumption in optical module and automatically controlling, redirect into step 230, that is, perform according to the data monitored
The corresponding power consumption control instruction step of traffic generating.
Automatically controlled, whereas if not opening power consumption in optical module, then optical module is in normal mode of operation all the time, that is, presses
Run according to the electric current in normal mode of operation, speed, clock data recovery unit working condition etc..
In one exemplary embodiment, method as described above can also comprise the following steps：
Out code is received, is cited sb. for meritorious service by out code in optical module acceptance of the bid and consumes the closing automatically controlled.
During optical module automatically controls to power consumption, it can close what optical module was currently carried out as needed
Power consumption automatically controls, and mitigates the processing pressure of optical module with this.
For example, when optical module monitors that main frame flow is consistently higher than 90% within a certain period of time, or, current slot
It is in peak period.
Or main frame is by the default reducing power consumption pattern of low-speed communication interface active inquiry optical module, and then according to looking into
Ask obtained default reducing power consumption pattern and issue out code to optical module.
As it was previously stated, the mark that power consumption automatically controls is configured with optical module, then the mark automatically controlled by the power consumption
Acceptance of the bid is cited sb. for meritorious service the closing that automatically controls of consumption, you can closes optical module and power consumption is automatically controlled.
Still illustrated with register form, the numerical value of register then marked the opening and closing that power consumption automatically controls.
When the numerical value of register is 0, the closing that automatically controls of mark power consumption.Similarly, the numerical value of the register can make according to reality
It is adjusted with needs.
Further, in the closing that power consumption automatically controls, it is controlled by the reception of out code.That is, power consumption automatically controls
Closing be execution to out code.
Further, out code can be issued by main frame, can also be in optical module test process, by surveying
Examination personnel input.For example, passed through by main frame under I2C (Inter-Integrated Circuit IC bus) interface
Hair, or, inputted by tester by serial communication interface.
The closing automatically controlled with power consumption, optical module can actively recover to enter normal mode of operation, can also enter one
Step ground enters default reducing power consumption pattern accordingly according to the instruction of main frame.
More preferably, referring to Fig. 6, method can also comprise the following steps as described above：
Step 310, the power consumption master control instruction that Receiving Host issues.
Power consumption master control instruction is different from the power consumption control instruction of optical module generation, the closing automatically controlled with power consumption, light
Power consumption master control instruction in module is issued by main frame.
Further, power consumption master control instruction is transmitted by the low-speed communication interface configured between main frame and optical module
's.For example, the low-speed communication interface can be I2C interface.
Certainly, if in optical module test scene, power consumption master control instruction can also be passed through by tester it is serial
Communication interface input.
Step 330, default reducing power consumption pattern accordingly is entered according to the power consumption master control instruction control optical module received.
After the power consumption master control instruction that main frame issues is received, control optical module can be instructed to enter according to the power consumption master control
Enter the default reducing power consumption pattern of power consumption control instruction instruction, i.e. the power consumption of optical module, which automatically controls, is controlled by main frame.
As shown in fig. 7, in one embodiment, main frame is by performing step 410, to the default reducing power consumption mould of optical module
Formula is inquired about, and then is performed step 430 and issued out code to optical module.
For optical module, controlled automatically after out code is received, and by performing step 450 closing power consumption
System, and then perform the power consumption master control instruction that step 470 issues according to main frame and enter default reducing power consumption pattern accordingly.
Under the cooperation of above-described embodiment, the power consumption of optical module automatically controls can be according to actual use demand neatly
Open and close, not only contribute to mitigate the processing pressure of optical module, and optical module power consumption control is gone for not
With application scenarios and there is higher versatility.
In one exemplary embodiment, method as described above can also comprise the following steps：
At least one default reducing power consumption pattern is set in optical module.
Specifically, referring to Fig. 8, setting at least one default reducing power consumption pattern in optical module, may comprise steps of：
Step 510, it is at least one multiple default registers of default reducing power consumption pattern configurations.
Wherein, multiple default registers include electric current register, rate register and clock and data recovery unlatching mark
Register.
Further, electric current register includes bias current register and modulation electric current register, and rate register includes
Emission rate register and receiving velocity register, clock and data recovery, which opens marker register, includes transmitting clock and data recovery
Open marker register and receive clock and data recovery and open marker register.
Specifically, bias current register reflects the default bias current of optical module under corresponding data flow standard.
Modulation electric current register reflects the default modulation electric current of optical module under corresponding data flow standard.
Emission rate register reflects the default emission rate of optical module under corresponding data flow standard.
Receiving velocity register reflects the default receiving velocity of optical module under corresponding data flow standard.
When transmitting clock and data recovery unlatching marker register reflects the transmitting of optical module under corresponding data flow standard
The default operating condition of clock data recovery unit, that is, reflect transmitting clock data recovery unit whether normal work.
When reception clock and data recovery unlatching marker register reflects the reception of optical module under corresponding data flow standard
The default operating condition of clock data recovery unit, that is, reflect receive clock data recovery unit whether normal work.
Thus, when multiple default reducing power consumption patterns be present, for each default reducing power consumption pattern, only it is different from above-mentioned
The numerical value of multiple default registers is different.
Step 530, multiple default registers are entered according to data traffic standard corresponding at least one default reducing power consumption pattern
Row assignment.
For example, data traffic standard is less than reference data flow 30% for the data traffic of main frame, then corresponding
In default reducing power consumption pattern, bias current register reflects that the bias current of optical module under the data traffic standard lowers 60%,
Modulation electric current register reflects that the modulation electric current of optical module under the data traffic standard lowers 80%, launches receiving velocity register
Reflect that the emission rate of optical module and receiving velocity lower 50% respectively under the data traffic standard, clock and data recovery opens mark
Know register to reflect the transmitting clock data recovery unit of optical module under the data traffic standard and receive clock and data recovery list
Member does not work.
Thus, completed according to the data traffic standard in default reducing power consumption pattern after the assignment of register, just in optical mode
It is provided with block and reducing power consumption pattern is preset corresponding to the data traffic standard --- reducing power consumption pattern four.
In the presence of above-described embodiment, the default reducing power consumption pattern pre-set in optical module is and data traffic standard
It is associated, so ensure that optical module power consumption control and main frame data traffic it is closely related, also as optical module power consumption
Automatically control and provide sufficient guarantee.
In one exemplary embodiment, optical module includes an at least passage.
Correspondingly, step 250 may comprise steps of：
For the default reducing power consumption pattern of power consumption control instruction instruction, the numerical value of default register is included according to it and changes light
Each passage corresponds to the numerical value of work register in module.
Wherein, work register is relevant with the real work pattern of optical module.
Firstly the need of explanation, the real work pattern of optical module refers to the default drop work(entered during optical module operation
Consumption pattern.That is, real work pattern can be any one in the default reducing power consumption pattern pre-set in optical module.
Secondly, work register is relevant with real work pattern, refer to optical module operation when, bias current, modulate electric current,
Launch receiving velocity, launch the working condition of clock data recovery unit and receive the work shape of clock data recovery unit
Register involved by state etc..
On this basis, according to the numerical value of the default register included in default reducing power consumption pattern to above-mentioned work register
Numerical value be modified, just cause optical module real work pattern switching for power consumption control instruction instruction default reducing power consumption mould
Formula, and then under the conditions of according to the data traffic normal transmission monitored, the power consumption of optical module is effectively reduced.
Illustrated by taking above-mentioned reducing power consumption pattern four as an example, when the default deposit that optical module includes according to reducing power consumption pattern four
After the numerical value of device is modified to the numerical value of work register, optical module enters the biasing of reducing power consumption pattern four, i.e. optical module
Electric current lowers 60%, and the modulation electric current of optical module lowers 80%, and the emission rate and receiving velocity of optical module lower 50% respectively,
The transmitting clock data recovery unit and reception clock data recovery unit of optical module do not work, now, optical module and main frame
Between data traffic transmission still remain in less than the 30% of reference data flow, and the power consumption of optical module is effectively reduced
70%.
Further, because optical module according to number of channels can be divided into single channel optical module, channel optical module, more
Passage optical module etc..Therefore, for the optical module of different numbers of channels, work register therein is and number of channels phase
Matching, i.e., each passage is corresponding with respective work register.
Thus, substantially it is the numerical value that work register is corresponded to for each passage in the numerical value change of work register
It is modified, as shown in figure 9, in the different passages of optical module, the numerical value of work register is pressed corresponding to each passage
The numerical value of the default register included according to default reducing power consumption pattern is changed, and then make it that power consumption is in each passage
Reduce, so as to ensure that the overall all declines of power consumption of optical module.
For example, when real work pattern is normal mode of operation, keep optical module overall power constant, real work pattern
Switching to reducing power consumption pattern, optical module overall power have dropped 20%, and real work pattern switching is reducing power consumption pattern two for the moment
When, optical module overall power have dropped 50%, when real work pattern switching is reducing power consumption pattern three, under optical module overall power
70% is dropped, when real work pattern switching is reducing power consumption pattern four, optical module overall power have dropped 90%.
It is noted that default reducing power consumption pattern includes normal mode of operation, now, according in normal mode of operation
The change for the work register numerical value that the numerical value of default register is carried out, you can preset deposit to be so that in normal mode of operation
The numerical value of device is consistent with the numerical value of work register, and then causes the numerical value of work register to keep constant, that is, keeps optical module
Overall power is constant.
Certainly, in other embodiments, the number amount and type for presetting reducing power consumption pattern can be neatly according to the need of reality
To ask and be configured, i.e., default reducing power consumption pattern can also not include normal mode of operation, or, preset reducing power consumption pattern and include more
Multiple reducing power consumption patterns.
In general, as shown in figure 9, when optical module is in normal mode of operation, optical module normal operation.
When the real work pattern of optical module switches to remaining any default reducing power consumption pattern by normal mode of operation,
Reduce bias current, the modulation electric current of optical module.Also, when gradually switching to reducing power consumption pattern four by reducing power consumption pattern one, light
Bias current, the modulation electric current of module also correspondingly gradually reduce.
When optical module enters reducing power consumption pattern three or reducing power consumption pattern four, reduce the emission rate of optical module, receive
Speed, and the working condition for launching clock data recovery unit and reception clock data recovery unit is cut by normal operating conditions
Shift to stop working state.In other words, when optical module is in reducing power consumption pattern one or reducing power consumption pattern two, optical module
Emission rate, receiving velocity and transmitting clock data recovery unit and receive clock data recovery unit working condition with
It is consistent during optical module normal operation.
It is noted that reducing power consumption pattern one and reducing power consumption pattern two belong to first kind reducing power consumption pattern, and reducing power consumption
Pattern three and reducing power consumption pattern four belong to the 3rd class reducing power consumption pattern.
Following is embodiment of the present disclosure, can be used for performing the optical module power consumption control method involved by the disclosure.
