Fig. 4 is a schematic flow chart of a control method of an optical fiber communication module according to an embodiment of the present invention.
The embodiment of the invention correspondingly provides a control method of an optical fiber communication module, which comprises the following steps:
s10, after the power consumption control function is turned on, the control signal transmission driving module 1 performs a work power consumption reduction operation, and transmits a first laser test signal with a corresponding intensity to a first communication device with an optical fiber communication function through an optical fiber according to the test signal until detecting that a detection result carried in the received detection signal is abnormal communication.
Wherein the detection signal is: and the first communication equipment carries out the detection work of whether the current optical fiber communication is normal or not according to the first laser test signal, and feeds back a signal for converting a second laser test signal carrying a detection result.
Compared with the prior art, the control method of the optical fiber communication module disclosed by the embodiment of the invention controls the sending driving module to continue to perform the operation of reducing the working power consumption according to the detection result carried by the received detection signal after the power consumption control function is started, and intelligently adjusts the power consumption of the sending driving module, so that the optical fiber communication module does not need to communicate according to the maximum working power consumption all the time, and the power consumption of the optical fiber communication module during optical fiber communication is effectively reduced.
As an improvement of the above scheme, the test signal is a preset error code test check signal.
In this embodiment, the power controller needs to send a certain number of data packets and specific check information to the first communication device through the error code test check module 41, and the code pattern of the check communication may be a PRBS-7 code or other code patterns, which is not limited herein.
The second laser test signal is: and the first communication equipment converts the received first laser test signal into a corresponding error code test check signal, performs error code check on the error code test check signal, and sends the corresponding laser test signal according to an error code check result.
In this embodiment, after receiving the data packets and the check information, the first communication device calculates whether the received data has an error code through a specific check algorithm (e.g., CRC check), generates a corresponding laser test signal according to the information whether the error code exists, and returns the laser test signal to the optical fiber communication module. So that the fiber optic communication module determines whether the emitted optical power can continue to be reduced.
And the detection result shows that the error code test check result is that no error code exists in normal communication, and the detection result shows that the error code test check result is that an error code exists in abnormal communication.
In this embodiment, the emitted light power may be continuously reduced by a certain step value until the error test check result indicates that an error exists. Then the optical fiber communication module takes the emitted optical power of the communication and increases the step value and adds a certain margin as the emitted optical power of the final actual operation.

s11, sending a query signal to the first communication device through the optical fiber until receiving an idle signal returned by the first communication device according to the query signal.

S13, if the busy signal of the first communication device is received within a preset time, continuously sending a query signal to the first communication device until receiving an idle signal returned by the first communication device according to the query signal.
Specifically, if a busy signal of the first communication device is received within a preset time, it indicates that the first communication device has a power consumption control function, but cannot immediately perform communication. Therefore, it is necessary to continuously transmit the query signal to the first communication device until the first communication device returns an idle signal, so that the first communication device can immediately communicate with the optical fiber communication module.
As an improvement of the above solution, the control signal transmission driving module 1 performs an operation of reducing operating power consumption, including:
according to the obtained current environment temperature, a power consumption adjustment correction value corresponding to the environment temperature value is searched from a preset environment temperature lookup table, and the adjustment amount of the current working power consumption reduction of the signal sending driving module 1 is controlled according to the power consumption adjustment correction value.

The signal driving end of the laser 3 is connected with the signal output end of the signal transmitting driving module 1, and the signal output end of the laser 3 is connected with the signal input end of the signal receiving conversion module 2.
The laser 3 is further configured to receive a second laser test signal sent by the first communication device through the optical fiber; the second laser test signal is: and the first communication equipment calculates the length of the optical fiber according to the received first laser test signal and feeds back a test signal carrying an optical fiber length measurement result.
The optical fiber communication power consumption control module 4 is configured to send a corresponding test signal to the signal sending driving module 1 after the power consumption control function is started; and the signal transmission driving module 1 is also used for controlling the corresponding operation power consumption reduction operation according to the length measurement result carried in the detection signal.
Compared with the prior art, according to the optical fiber communication module disclosed in the embodiment of the invention, after the power consumption control function is started, the signal transmission driving module 1 outputs a corresponding driving signal according to the test signal to drive the laser 3 to transmit a corresponding first laser test signal to the first communication device, the first communication device calculates the length of the optical fiber according to the received first laser test signal to obtain a test signal (namely, a second laser test signal) carrying an optical fiber length measurement result, which is fed back, the signal reception conversion module 2 converts the second laser signal into a corresponding detection signal, and the signal transmission driving module 1 is controlled to perform corresponding work power consumption reduction operation according to the length measurement result carried in the detection signal.

For example, if the length of the optical fiber is known, the emitted light power can be adjusted by a preset value written in a memory in advance. Such as: when the lengths of the external optical fibers are respectively 100 meters, 500 meters, 1000 meters, 1500 meters and 2000 meters, the memories in the optical fiber communication power consumption control module 4 store corresponding emission light power rated values meeting normal operation, and when the lengths of the external optical fibers are obtained, the values of the emission light powers can be adjusted according to set values written into the memories in advance. When the optical fiber is short, the rated value of the transmitting optical power required by the signal transmitting driving module 1 is lower than that when the optical fiber is long, so that when the optical fiber line is short, the transmitting optical power can be effectively reduced by adopting lower transmitting optical power. The optical fiber communication module does not need to communicate according to the maximum working power consumption all the time, and the power consumption of the optical fiber communication module during optical fiber communication is effectively reduced.
