In prior art, the transmitting terminal of optical module generally carries adaptive equalization function, after optical module powers on, optical mode
The transmitting terminal of block i.e. directly initiates adaptive equalization function, to reach to obtain the purpose of equilibrium value.But be in this case
The situation of the electrical modulation signal that system veneer is supplied to optical module is uncertain, when i.e. transmitting terminal starts adaptive equalization function,
System single board may have been applied to optical module electrical modulation signal, it is also possible to does not provide.And do not provide at system single board
During electrical modulation signal, transmitting terminal opens adaptive equalization function, may result in the problem that adaptive equalization is failed.
For the problems referred to above, the invention provides the adaptive equilibrium method of a kind of optical module, the method is by opening
Before adaptive equalization, first LOS warning signal is judged, just open self adaptation when determining and not producing LOS warning signal
Equilibrium, thus avoid when system single board does not the most provide electrical modulation signal to optical module, it is equal that optical module is switched on self adaptation
The problem that the weighing apparatus adaptive equalization that caused of function is failed.
The schematic flow sheet of the automatic balancing method of the optical module that Fig. 1 provides for the embodiment of the present invention one, the method is permissible
Performed by an optical module.As it is shown in figure 1, the method that the present embodiment provides comprises the steps:
Step S101, determining whether to create synchronization loss LOS alarm, wherein, accusing if creating synchronization loss LOS
Alert, then perform step S102, otherwise perform step S103.
In actual application, optical module powers on, and after completing initial work, from the depositor having LOS warning information
Obtain LOS warning information, it is determined whether create LOS alarm.I.e. determine whether the veneer of system provides electricity tune to optical module
Signal processed.
In actual application, when optical module detects that veneer provides electrical modulation signal, LOS is high resistant, and now LOS is high
Level, does not produce LOS alarm.Otherwise, when being not detected by the electrical modulation signal that veneer provides, now LOS is pulled low, and produces
LOS alerts.The present embodiment determines whether to create LOS alarm according to this principle just.
Step S102, it is not turned on adaptive equalization.
In actual application, when optical module determines that creating LOS alarm, i.e. optical module does not receives what system single board provided
During electrical modulation signal, optical module is not turned on adaptive equalization function, and is to continue with detecting electrical modulation signal, until detection
To electrical modulation signal, after LOS alarm eliminates, it is then turned on adaptive equalization.
Step S103, unlatching adaptive equalization.

Then perform step S203.
In actual application, LOL alarm can be used for monitoring whether phaselocked loop is locked in reception data stream, when phaselocked loop non-locking
When receiving data stream, then can produce LOL warning information.In the present embodiment, when optical module determines that phaselocked loop non-locking veneer provides
Electrical modulation signal time, will produce LOL alarm.Optical module is determined by whether creating LOL alarm, i.e. can determine that system list
Whether plate provides electrical modulation signal.Even if so that optical module is in the case of system single board noise is relatively big, also will not be by
In the erroneous judgement of LOS warning signal, and cause the problem that adaptive equalization is failed.
Step S202, unlatching adaptive equalization.
In the present embodiment, only when optical module had not both generated LOS alarm, did not generated LOL alarm yet, just open self adaptation
Equalization function.It is thus possible to avoid the problem that the adaptive equalization that caused due to the erroneous judgement of LOS warning signal is failed.
Step S203, it is not turned on described adaptive equalization.
The present embodiment is by judging LOS warning information and LOL warning information, and does not only generate at optical module
When LOS alarm and LOL alert, just open adaptive equalization function, be otherwise not turned on.Even if so that optical module is at system list
In the case of plate noise is relatively big, also due to the erroneous judgement of LOS warning signal, and the problem that adaptive equalization is failed will not be caused.
In practical situation, if be shut off adaptive equalization merit when the adaptive equalization function of optical module is also not fully complete
Can, now also result in adaptive equalization failure.In view of this problem, the embodiment of the present invention three provides oneself of a kind of optical module
Dynamic equalization methods, the method is not fully complete period in adaptive equalization, if main frame sends the order cutting out adaptive equalization, the most temporarily
It is not responding to this order, after adaptive equalization completes by the time, then responds this order.By this method it can be avoided that due to from
Adaptive equalization is not fully complete and is shut off the problem that adaptive equalization that adaptive equalization function caused is failed.
