Description

Technical Field

[0001] The present invention relates to the technical field of optical module control, and in particular to an optical module control method, an optical module control device and an optical module. Background Art

[0002] The optical module is a very important optical signal interface device in optical fiber communication, which is used to convert between optical signals and electrical signals. The optical module mainly includes a controller, a laser, a detector, a laser driver chip, and an amplifier. The laser driver chip is used to provide a driving electrical signal to the laser to drive the laser to emit an optical signal and transmit it through the optical fiber. The detector receives the optical signal from the optical fiber and converts it into an electrical signal. The amplifier is used to amplify the electrical signal output by the detector. The controller is used to send control signals to the laser driver chip and receive electrical signals sent by the amplifier. As the signal transmission power increases, heat dissipation of the optical module is crucial.

[0003] For example, the Chinese patent announcement number is CN118367434A, which discloses an optical module and its control method, device, and computer-readable storage medium. The comparative patent solves the problem of enabling the heating module to heat the laser when the actual ambient temperature is less than the preset low temperature threshold. The optical module provided can eliminate the influence of the low temperature environment on the internal resistance of VCSEL to improve the transmission performance of VCSEL, and can also be applied to the heat dissipation of the optical module.

[0004] The applicant found that when the optical module always keeps working at full load, the power consumption of the optical module will be too large, and the heat generation of some main modules in the module (light detection diode and laser) will continue to increase. Even if the heat is dissipated by the heat dissipation device, the light detection diode or laser is always in a slow load working state, so that heat will be generated all the time, and the heat dissipation effect is not ideal. Moreover, the large amount of heat generated while working at full load for a long time will affect the normal operation of the optical module. That is, the existing heat dissipation of the optical module cannot use the heat dissipation device to dissipate the light detection diode and laser on the basis of reducing the load and not affecting the normal operation. Summary of the invention

[0005] The object of the present invention is to provide an optical module control method, device and optical module, which are capable of starting an auxiliary light detection diode or auxiliary laser when the temperature of the main light detection diode or main laser in the optical module is high, without affecting the normal reception and emission of light, and also achieves the purpose of reducing the load of the main light detection diode and the main laser. Reducing the load of the main light detection diode and the main laser reduces the power output, reduces the heat generation in the optical module, promotes the heat dissipation of the main light detection diode and the main laser, and solves the problems raised in the background technology.

[0006] To achieve the above object, the present invention provides the following technical solution: a method for controlling an optical module, comprising the following steps:

[0009] S3, monitoring the temperature of the main light detection diode and the main laser surface in real time, and comparing the monitored temperature with the maximum temperature threshold;

[0010] S4 If the monitored temperature is lower than the maximum temperature threshold, the main light detection diode or the main laser works alone;

[0011] S5. If the monitored temperature is higher than the maximum temperature threshold, the auxiliary light detection diode or the auxiliary laser will be started to perform auxiliary work, and the heat dissipation module will be started to dissipate heat for the main light detection diode or the main laser until the surface temperature of the main light detection diode or the main laser is lower than the maximum temperature threshold.

[0012] Preferably, in S1, the power of the auxiliary light detection diode is lower than the power of the main light detection diode, the power of the auxiliary laser is also lower than the power of the main laser, and the main light detection diode and the main laser are mainly used in the optical module.

[0017] The auxiliary light detection diode is used to assist the main light detection diode in receiving light signals, that is, when the temperature of the main light detection diode reaches the maximum temperature threshold, the auxiliary light detection diode assists in receiving light signals, and converts the received light signals into electrical signals and sends them to the amplifier;

[0018] The laser driver is used to modulate the electrical signal transmitted through the interface, and send the modulated signal to the main laser first, and the main laser emits the optical signal. When the temperature of the main laser surface reaches the maximum temperature threshold, the laser driver will also send the modulated signal to the auxiliary laser to emit the laser signal to reduce the load of the main laser.

[0019] The temperature detection module is used to monitor the temperature of the main light detection diode and the main laser surface in real time, and send the monitored temperature signal to the micro-control module, and the micro-control module processes the received temperature signal;

[0020] The heat dissipation module is arranged on the main laser and the main light detection diode, and is used for monitoring the surface temperature of the main laser and the main light detection diode.

[0021] Preferably, the microcontroller module processes the received temperature signal and compares it with the maximum temperature threshold;

[0022] If the monitored temperature is lower than the maximum temperature threshold, the microcontroller module will not react, so that the main light detection diode or the main laser continues to work alone;

[0023] If the monitored temperature is higher than the maximum temperature threshold, the microcontroller module will control the auxiliary light detection diode or auxiliary laser to perform auxiliary work, and at the same time control the heat dissipation module to dissipate heat for the main light detection diode or main laser. When the temperature of the main light detection diode or main laser drops below the maximum temperature threshold, the microcontroller module will control the auxiliary light detection diode or auxiliary laser and the heat dissipation module to stop working.

[0046] The present invention can start the auxiliary light detection diode or the auxiliary laser without affecting the normal reception and emission of light, and also achieves the purpose of reducing the load of the main light detection diode and the main laser. Reducing the load of the main light detection diode and the main laser reduces the power output, reduces the heat generation in the optical module, and promotes the heat dissipation of the main light detection diode and the main laser.
