Description
Technical field
The present invention relates to the compatible technique of tunable laser, particularly relate to a kind of switch control compatibility method and device thereof of different tunable lasers.
Background technology
Requirement of system design can be replaced and be used different tunable laser, hardware system will do compatible design, as the position dimension compatibility of placing laser, shared pin compatibility, power supply electrical level compatibility etc.; Correspondingly on software, also to do compatible design.
Because tunable laser (abbreviating laser herein as) derives from different manufacturers, for the light index more unified standard is arranged, the number of pin, relative size size, communication interface, control mode all are not quite similar.The tunable laser that comprehensive each manufacturer at present provides mainly is divided into two kinds according to control mode: the tunable laser of band working parameter recording and no working parameter recording.
The tunable laser of band working parameter recording refers to that mainly those self have storage medium, externally be provided with parameter operation simultaneously record be updated in self storage medium, re-power, when satisfying the laser entry condition, automatically return to former operating state according to the data that are recorded in the storage medium, as original switching ring status, operation wavelength, on off state etc.Itself does not have storage medium the tunable laser of no working parameter recording, operating state is obtained and controlled is order-feedback system by between system and the laser fully, be laser can enter a kind of acquiescence after powering on state to be configured, system meets the requirements of operating state with command mode configuration laser as required.This tunable laser does not generally have bright dipping after powering on, do not know with what wavelength to open because it supports multi-wavelength, need carry out wavelength configuration after state-detection is normal at least, could normally open.
Can return to original operating state after requiring laser to re-power in the real system, especially with the communication system of tunable laser wavelength as business carrier, be to guarantee.After various reasons caused the components of system as directed disabler to be restarted, laser must be got back to other part operate as normal that original operating state could cooperate other system or system, otherwise does not just have self-healing ability, can not use on engineering.
The normal run time behaviour reference record of tunable laser of band working parameter recording is in the storage medium of self, and after restarting, self mini system will make laser return to original operating state according to recording parameters, does not need external system control; And the tunable laser of printenv record is in state to be configured after powering on, self can not recover original operating state, satisfy system from recovering requirement, need secondary storage medium and it incompatible the finishing that match, be about to the system running state reference record in the storage medium of system, be configured to laser by systems soft ware after waiting to power on, make it recover original operating state.
Simultaneously, system failure protection or light path are switched very high to time requirement, for example ought detect the system exception upstream device quick closedown laser etc. that needs protection.During software is realized to laser operation to be placed on interrupt or timer-operated Rapid Cycle detection task in carry out.Two kinds of lasers are all supported to obtain and control its state by command mode, obtain etc. as wavelength adjustment, switch, temperature, but no matter adopt which kind of communication bus or bidding protocol form, all be subjected to conditionality such as transmission rate, bus mode and acknowledgement mechanism and generation time postpones, under some situation, such laser switch control rate can not satisfy system requirements, and the power pin level of the optical transmitting set of general employing control laser is realized the high-speed switch control of laser.
Laser comprises two states in system: " expectation on off state " and " current on off state "." expectation on off state " is to obtain behind the various running statuses of integrated system and the external demand." current on off state " carries out the core that switch state is a laser works to " expectation on off state " conversion under system and exterior arrangement, its realization need be done and anatomize.
Two kinds of lasers in the above conditions, because the difference of working method exists a lot of differences in control, cause the running status difference mainly due to whether self has memory function, the tunable laser of band working parameter recording receives exterior arrangement (as new operation wavelength being set or opening and closing ring status) back recording parameters and disposes laser, even under the condition that optical transmitting set cuts out, treat when optical transmitting set is opened directly with new configuration effort; And the tunable laser of not having a working parameter recording is under the condition that optical transmitting set cuts out, because can't write down and invalid configuration, can not change original configuration, although reference record is in system's exterior storage medium, but for laser, remain exterior arrangement, when opening, optical transmitting set can not come into force simultaneously, also can be with original parameter operation, just then reconfigure new argument afterwards by system command, occur with two different wave lengths luminous and cause the laser state " to flash " in this process, can influence the signal that carries in the system, can not meet engine request.Also have, the requirement of laser switching speed, need to obtain fast laser " current on off state ", the tunable laser of band working parameter recording can obtain on off state fast according to the power pin level of optical transmitting set, and do not have the tunable laser of working parameter recording owing to when the command configuration wavelength is opened, must guarantee that the pin of optical transmitting set is a power supply state, therefore, when being out, the pin level of optical transmitting set can not determine the opening of laser.
Therefore, guarantee to be operated in the same system and satisfied control requirement, must carry out the softwarecompatible design with the tunable laser of working parameter recording and no working parameter recording.

Embodiment
Below in conjunction with the drawings and specific embodiments technical scheme of the present invention is made further more detailed description.
As shown in Figure 1, be the switch compatibility method flow chart of tunable laser of the present invention.In the figure, described tunable laser switch control procedure under system self decision-making and exterior arrangement, specifically comprised the steps: having the wavelength tuning function
Step S101, " the expectation on off state " of acquisition tunable laser;
In this step, move under system environments after the tunable laser initialization, its on off state is subjected to systematic influence and control, and " expectation on off state " is that various running statuses of integrated system and external demand obtain.
The tunable laser of band working parameter recording and the tunable laser of no working parameter recording adopt identical determination methods, change corresponding tunable laser switch process flow process over to according to " the expectation on off state " that obtain afterwards.
System protection or light path are switched requirement can turn-off tunable laser fast according to " expectation on off state " under abnormal conditions, therefore " expectation on off state " determining program moves in interruption or timer-operated Rapid Cycle detection task.
Step S102, " the current on off state " of acquisition tunable laser;
In this step, the tunable laser of band working parameter recording obtains " current on off state " by the power pin level of direct judgement optical transmitting set; And the tunable laser of not having a working parameter recording is not corresponding one by one because of the power pin level of optical transmitting set with on off state, therefore needs to introduce Status Flag and determine on off state.
The tunable laser of no working parameter recording itself can not the recording parameters state, though the exterior arrangement parameter can be recorded in the memory block of system, but these parameters remain peripheral operation for laser, no matter which kind of reason causes these parameter changes, all needing to reconfigure laser by order just can come into force, therefore introduce the Status Flag whether the reflection laser was newly disposed, as long as (as having closed optical transmitting set) made parameter configuration under laser can not the response external command situation, this indicates effectively and storage configuration parameter in system, wait for that laser issues institute's stored configuration parameters in the time of can responding, sign lost efficacy this moment, and the expression laser does not have store status to be configured.This sign and the power pin level of optical transmitting set can unique definite no working parameter recording the current on off state of tunable laser, promptly sign effectively (configuration) be off status; The optical transmitting set power supply that indicates invalid (disposing) is opened for laser, does not power to be the laser pass.
Step S103, control tunable laser " current on off state " is to the conversion of " expectation on off state "; This step comprises closes the compatible processing of operation and to the compatible processing of tunable laser ON operation to tunable laser.
Wherein, the compatible processing that two kinds of tunable laser are closed operation is specifically:

For ON operation, influenced by the configuration status of tunable laser itself, the time of opening is uncertain, only is provided with in interruption or the timed task and opens the global variable sign, finishes ON operation according to this unlatching global variable sign in the timeless duty cycle of system.
Wherein, specifically to the compatible processing of two kinds of tunable laser ON operations:
1) tunable laser of band working parameter recording is directly controlled the power pin level of optical transmitting set;
2) tunable laser of no working parameter recording is distinguished according to configuration status sign (or be called laser wait to open sign), out-of-date when disposing, i.e. expression before had been configured and had opened this tunable laser, directly controlled the power pin level of optical transmitting set and opened; When new configuration status sign, i.e. expression has been write down other configuration but has not been operated this tunable laser, earlier close this tunable laser by order, give the power pin level power supply of optical transmitting set then, open this tunable laser (command communication mode) with the wavelength of record more at last.Order is closed the operation of this tunable laser and has been avoided the pin of optical transmitting set directly to power to this tunable laser, and it is directly opened with former wavelength, just wavelength adjustment and produce service wavelength and switch (wavelength " flashes ") under new wavelength configuration order then reaches directly to be recorded in wavelength in system's storage and starts the purpose of this tunable laser.
Can realize that according to top method two kinds of tunable laser operate in the optical transmission system, transparent fully for peripheral operation, two kinds of tunable laser can be directly replaced and configuration mode needn't be changed.
As shown in Figure 2, be the compatibility processing method flow chart of " expectation on off state " judgement of two kinds of tunable laser of the present invention.
" the expectation on off state " of two kinds of tunable laser is that the various running statuses and the external demand of integrated system obtains, two kinds of tunable laser adopt identical determination methods, change corresponding switch process flow process when obtaining " expectation state " over to, finish control tunable laser by relatively " current state " and " expectation state ".This flow process specifically comprises:
