[0034] Figure 3 A flowchart of the working principle of the optical module intelligent energy-saving device is provided for the embodiments of the utility model. As shown in the figure, Figure 3 the principle of the embodiment is specifically as follows:

[0035] S100, read the temperature and judge whether the optical module is in a stable working state;

[0036] S200, when the optical module is in a stable working state, adjust the output voltage of the DC-DC module, read the input current and calculate the power consumption of the optical module;

[0037] S300, according to the power consumption of the optical module, adjust the output voltage of the DC-DC module to the lowest power consumption voltage, write the DDM temperature of this working state into the EEPROM T1 position, and at the same time, write the EEPROM power consumption state Power level position 1 in the MCU, indicating that the power consumption adjustment of this temperature has been completed;

[0038] S400, the MCU module reads the Tx input signal state of the CDR module and adjusts the CDR module TX input signal;

[0039] S500, as the environmental temperature changes, the module working temperature changes correspondingly, and when the temperature change exceeds 10C, the DC-DC module is readjusted and the new lowest power consumption voltage is updated.

[0040] The following will specifically describe each step:

[0041] S100, read the temperature and judge whether the optical module is in a stable working state;

[0042] The judgment method of the stable working state is that the MCU control module continuously reads the DDM temperature of the optical module 10 times, detects whether the temperature change is more than 2 DEG C, if the temperature difference is not more than 2 DEG C, the optical module is in a stable working state, otherwise, the optical module is in an unstable working state.

[0043] S200, when the optical module is in a stable working state, adjusting the output voltage of the DC-DC module, reading the input current, calculating the optical module power consumption;

[0044] S300, according to the optical module power consumption, adjusting the DC-DC module output voltage to the lowest power consumption voltage, writing the DDM temperature of this working state to the EEPROM T1 position, and at the same time, setting the MCU internal EEPROM power level position 1, indicating that the power consumption adjustment of this temperature has been completed;

[0045] The power level position 1 indicates that the power consumption of the optical module has been adjusted to the lowest state at the current temperature.

[0046] S400, the MCU module reads the Tx input signal state of the CDR module, and adjusts the CDR module TX output signal;

[0047] The Tx input signal state of the CDR module is Tx LOS, indicating that the module does not receive the input signal, and the device has not transmitted the signal normally, then the MCU controls the CDR to close the Ibias bias current and the imod modulation current, further reducing the power consumption; The Tx input signal state of the CDR is Tx LOS OFF, and the Tx Turn ON signal needs to be transmitted normally, then the MCU controls the CDR to normally open the Ibias bias current and the imod modulation current, so that the optical module can work normally.

[0048] S500, as the environmental temperature changes, the module working temperature also changes, and when the temperature change exceeds 10 DEG C, it is necessary to re-adjust the DC-DC module to update the new lowest power consumption voltage;

[0049] Because the working state of the semiconductor device is greatly affected by temperature, when the Real DDM Temp and the EEPROM T1 temperature difference exceeds 10 DEG C, the previously set Vout voltage may not be the lowest power consumption voltage, it is necessary to set the power level state to 0, and then re-adjust the DC-DC to find the lowest power consumption, and then write the latest DDM temp to the EEPROM T1 position and set the power level state to 1.

[0050] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
