Embodiments provide a kind of control method of luminous power, as shown in Figure 2, said method comprising the steps of:
201, after powering on or losing light, optical power attenuation device is adjusted to initial decay state by controller.
After optical module powers on, described controller can be adjusted to initial decay state optical power attenuation device.Described initial decay state refers to that one presets, can by larger for the optical power attenuation of incident light state, when described optical power attenuation device is under described initial decay state, after incident light enters optical module, stronger power attenuation will be carried out by described optical power attenuation device, ensure that described incident light can not burn described optical module.

Described controller can regulate the magnetic field at its two ends by the voltage changing Faraday rotator two ends, thus regulates the anglec of rotation of described Faraday rotator.The initial decay state of described Faraday rotator can be the anglec of rotation of described Faraday rotator is unspecified angle in 1 degree to 5 degree, such as, state when 5 degree, described Faraday rotator is in initial decay state, can ensure to carry out larger decay to incident light, can not optical module be burnt.
202, atr plate will reach the reflected incident light of described optical module to described optical power attenuation device.
The incident light reaching described optical module can all be reflexed to described optical power attenuation device by atr plate by described optical module.Because the incident light reflected by atr plate refraction effect can not occur, therefore can all enter optical power attenuation device, thus avoid the loss of incident light.
203, described optical power attenuation device is decayed at the power of current attenuation state to described incident light.
First current attenuation state of described optical power attenuation device is described initial decay state, and described optical power attenuation device carries out power attenuation to the power of incident light under described initial condition.
When described optical power attenuation device is Faraday rotator, described Faraday rotator, under initial decay state, such as, when the anglec of rotation is 5 degree, is decayed to the luminous power of incident light.

The signal of telecommunication is changed into by photodiode by the incident light after described optical power attenuation device carries out power attenuation, described controller can detect the power of the described signal of telecommunication by luminous power testing circuit, and judges whether the power of the described signal of telecommunication meets reception requirement.Described luminous power testing circuit can be arranged in the controller, also independent of controller, and can be connected with described controller.Described reception requires to include the power required by described optical module, described optical module needs to convert the incident light received to electric signal transmission to host computer, the described signal of telecommunication must reach certain performance number, described host computer could receive this signal of telecommunication effectively, therefore described reception requirement can be less than the minimum power burnt needed for described optical module for the minimum power that is greater than needed for described host computer; Or, also can be less than a performance number of the minimum power burnt needed for described optical module for the minimum power that is greater than needed for described host computer.The power of the described signal of telecommunication meets described reception requirement, will ensure that described optical module both can not be burnt, and can ensure that again described host computer can effectively receive this signal of telecommunication.
Described controller can be internal integrated circuit (Inter Integrated Circuit, be called for short IIC), media independent interface management (Media Independent InterfaceManagement, be called for short MIIM) controller, also can be Serial Peripheral Interface (SerialPeripheral Interface is called for short SPI) controller.
If controller detects that the power of the described signal of telecommunication meets and receives requirement, then carry out step 206, if controller detects that the power of the described signal of telecommunication does not meet receive requirement, then carry out step 207.
206, successful for adjustment state information and the described signal of telecommunication are uploaded to host computer by described controller, receive the described signal of telecommunication to make described host computer.
If the power of the described signal of telecommunication meets receive requirement, then show the optical power adjustment success of optical module to incident light, successful for adjustment state information and the described signal of telecommunication are uploaded to host computer by described controller, start working and receive the described signal of telecommunication to make described host computer.
207, described controller by described optical power attenuation device from current attenuation status adjustment to next attenuation state.
If the power of the described signal of telecommunication does not meet described reception requirement, then described controller by described optical power attenuation device from current attenuation status adjustment to next attenuation state, then re-start after the incident light after being carried out power attenuation by described optical power attenuation device is converted to the signal of telecommunication by described photodiode by step 204, carry out step 205, again the power of the signal of telecommunication is detected, if still do not meet described reception requirement, then continue described optical power attenuation device from current attenuation status adjustment to next attenuation state, then step 204 and 205 is performed, until described controller detects that the power of the described signal of telecommunication meets receive requirement.
Here, the optical power attenuation device being in described current attenuation state is larger than the power of the optical power attenuation device decay being in next attenuation state described, like this along with the adjustment of optical power attenuation device, the luminous power of the incident light after being carried out power attenuation by described optical power attenuation device increases gradually, until the power of the described signal of telecommunication changed into by the incident light after described optical power attenuation device carries out power attenuation increases to the reception requirement meeting described optical module.If the attenuation state of described optical power attenuation device has reached the most weak, the power of the signal of telecommunication does not still meet described reception requirement, then show that the power of the signal of telecommunication is too weak, reception requirement cannot be met, now, unsuccessful for adjustment state information is uploaded to host computer by described controller, does not carry out reception operation to make described host computer.
