Optical signal processing method can also be applied in the optical module in OLT.
Fig. 2 is the schematic flow sheet of optical signal processing method embodiment one provided in an embodiment of the present invention, should
The executive agent of method is the optical module in ONU and/or OLT, as shown in Fig. 2 this method includes：
S101, optical module receive the optical signal that light signal transmitting is sent.
Wherein, light signal transmitting can be above-mentioned ONU and/or OLT, if that is, optical module refers to
Optical module in ONU, then light signal transmitting is OLT；If optical module refers to the light in OLT
Module, then light signal transmitting is ONU.In following embodiments of the embodiment of the present invention, all with ONU
In optical module exemplified by illustrate, but it should be evident that this method also can be completely applied in OLT
Optical module.
The module with light-receiving function and emission function, such as optical module can be included in ONU.ONU
The optical signal of OLT transmissions can be received by optical module.
S102, optical module judge whether the luminous power of optical signal is less than the first predetermined threshold value, if being less than,
Optical module sends to light signal transmitting and receives prompt message.
Luminous power can be for weighing the intensity of optical signal, can be real-time after optical module receives optical signal
The luminous power of optical signal is monitored, once luminous power is reduced to the first predetermined threshold value, then illustrates the strong of optical signal
Degree declines seriously, then optical module can send to OLT and receive prompt message, and the information is a kind of warning message,
For alerting OLT its issued light signal intensity declines, OLT is needed when receiving reception prompt message
The luminous power of transmitted optical signal is adjusted in time, to ensure that the optical signal subsequently sent is normal.And such as
The optical signal that fruit OLT is subsequently sent is as current light signal strength or weaker, it is necessary to stop hair
Send optical signal.But simultaneously, optical module can't stop the optical signal that reception processing OLT is retransmited.
Wherein, the first predetermined threshold value can be selected according to the actual treatment ability of optical module, and it is set
Principle be：First predetermined threshold value than optical module can not reception processing optical signal when corresponding optical power value it is big
Certain value.So as to ensure optical module after warning message is transmitted across to OLT according to the first predetermined threshold value also
It can continue to normally receive the optical signal that processing OLT is sent.
S103, optical module judge whether the luminous power of optical signal is less than the second predetermined threshold value, if being less than,
Optical module stops reception processing optical signal, also, sends LOS information to light signal transmitting, should
LOS information is used to notify the light signal transmitting optical module can not receive optical signal.
Wherein, the second predetermined threshold value is less than the first predetermined threshold value.
Specifically, as it was previously stated, when the luminous power for the optical signal that optical module is received is preset already less than first
During threshold value, such as during -28dbm, optical module can send warning message to OLT.On this basis, light
Module may proceed to the optical signal of reception processing OLT transmissions, meanwhile, optical module also may proceed to monitor light in real time
The luminous power of signal, when luminous power continues to drop to the second predetermined threshold value, such as when -35, optical module is
Through that can not normally receive processing optical signal, then now optical module can stop reception processing optical signal, meanwhile,
Optical module can to OLT send LOS information, i.e. announcement information, allow OLT recognize optical module without
Method reception processing optical signal, OLT is needed after the luminous power of the optical signal of adjustment transmission, and optical module just may be used
To normally receive the optical signal transmitted by OLT.
Due to optical module, warp-wise OLT has been transmitted across warning message in advance, and OLT is receiving warning message
Afterwards, if the optical power value of optical signal does not improve, OLT will not send optical signal to optical module again,
Therefore, when optical module stops reception processing optical signal according to the second predetermined threshold value, there will not be OLT again
Sending and optical signal that optical module can not be handled.Also, optical module is sent out again to OLT once notifies letter
Breath, can cause OLT to adjust corresponding sending strategy according to the announcement information.
In the present embodiment, optical module when the optical power down of the optical signal received is to the first preset value to
Light signal transmitting sends warning message, to indicate the light signal transmitting transmitted light of adjustment in time
The luminous power of signal, it is to avoid retransmit the too small optical signal of luminous power, meanwhile, in the process, i.e., from
Optical module detection optical signal drops to the first predetermined threshold value until light signal transmitting receives warning message
During, optical module can't stop the optical signal of reception processing light signal transmitting transmission, but
Continue to handle these optical signals, when optical module is according to the second predetermined threshold value stopping reception processing optical signal
When, the prompting message that light signal transmitting has been sent in advance according to optical module stops sending optical signal,
Be not in the optical signal that light signal transmitting be have sent and optical module can not be received, so as to avoid production
The problem of third contact of a total solar or lunar eclipse dropout.

High level signal sends LOS information to light signal transmitting.
Specifically, optical module can produce a high level signal, and root while stopping and receiving optical signal
According to the high level signal, LOS information can be correspondingly generated.
Pass through the above-mentioned of optical module so that judgement los state that optical module can be rapidly and efficiently is simultaneously believed to light
Number send equipment send LOS information.
Further, on the basis of above-described embodiment, the present embodiment is related to optical module and sends reception prompting
Processing procedure before information.Specifically, reception is sent to light signal transmitting in foregoing optical module to carry
Before showing information, in addition to：
Optical module generates low level signal, and the low level signal is used to indicate that optical module continues to handle light
Signal.
Specifically, as it was previously stated, optical module can't stop connecing when sending to OLT and receiving prompt message
Processing optical signal is received, and this process is realized by the low level signal produced by optical module.Light
The luminous power for the light that module is received is more than or equal to the first predetermined threshold value, then illustrates that optical module can also continue to
Reception processing optical signal, in this case, optical module can produce a low level signal, according to the letter
Number received optical signal is normally handled, so as to ensure the normal transmission of optical signal.
On the basis of above-described embodiment, the present embodiment is related to the mistake that optical module recovers reception processing optical signal
Journey.I.e. after foregoing optical module stops reception processing optical signal, in addition to：

Whether luminous power is more than or equal to the 3rd predetermined threshold value, if so, then optical module generation low level signal, this is low
Level signal is used to indicate that optical module continues to handle optical signal, also, optical module is sent to optical signal
Equipment, which is sent, to be recovered to receive announcement information, and the recovery, which receives announcement information, to be used to notify light signal transmitting,
Optical module has restarted reception processing optical signal.
Wherein, the 3rd predetermined threshold value is more than the first predetermined threshold value.If for example, the first predetermined threshold value be -28dbm,
3rd predetermined threshold value can be -26dbm.
Specifically, after optical module stops the optical signal that reception processing OLT is sent, OLT sides need hair
The luminous power of the optical signal sent may be restored to normal condition, in this case, and OLT may
Again optical signal can be sent to optical module.After optical module receives the optical signal of OLT transmissions again, optical module
Can judge whether these optical signals reach can normally receive the standard of processing, if reached, optical module
Foregoing low level signal is generated by the module therein with light-receiving function, this low level is believed
Number being transferred to processing module is handled, and then, processing module can normal process these optical signals.Enter one
Step ground, processing module can also generate recovery and receive announcement information, for allowing OLT to recognize optical module
