[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

SeeFigure 1 , Figure 2 and Figure 3 , the optical module 140 includes: a transmitting end 150, a receiving end 160, a light source module 120, a control module 110, and a receiving module 130;

[0033] The control module 110 is configured to generate a first control signal according to digital diagnostic information;

[0034] The light source module 120 is respectively connected to the control module 110 and the transmitting end 150; the light source module 120 is configured to generate a first modulated optical signal according to the first control signal, and transmit the first modulated optical signal to the transmitting end 150; the transmitting end 150 is configured to connect to an external device 163, and transmit the first modulated optical signal to the external device 163;

[0035] The receiving module 130 is respectively connected to the control module 110 and the receiving end 160; the receiving end 160 is configured to connect to the external device 163, and receive a second modulated optical signal sent by the external device 163;

[0036] The receiving module 130 is configured to generate a second control signal according to the second modulated optical signal; the control module 110 is further configured to adjust the working state of the optical module according to the second control signal.

[0037] Specifically, digital diagnostic information is obtained by real-time monitoring of operating parameters such as the working voltage and temperature inside the optical module. The digital diagnostic information can reflect potential problems of the optical module. For example, if the working voltage is too high, it is easy to break down the CMOS device of the optical module; if the working voltage is too low, the optical module cannot work properly. If the received power is too high, it will damage the receiving device of the optical module. If the working temperature is too high, it will accelerate the aging of the device. Among them, the implementation of digital diagnostic monitoring is an existing technology and will not be elaborated here. The control module 110 generates a first control signal according to the digital diagnostic information. Among them, the first control signal is a modulation signal of the light source module 120. The light source module 120 can generate a modulated optical signal according to the first control signal. Among them, the modulated optical signal contains digital diagnostic information, such as parameter information such as working voltage and working temperature. The modulated optical signal emitted by the light source module 120 is transmitted to the transmitting end 150, and the digital diagnostic information of the optical module is transmitted in the form of an optical signal through a waveguide. After connecting to the receiving port 161 of the external device 163, the external device 163 is used for demodulation and reading, so that the digital diagnostic information of the optical module can be obtained. On-site maintenance personnel can receive and judge the state of the optical module without interrupting the working service of the optical module. Among them, the external device 163 can be an independent reading device, which can demodulate the optical signal of the light source module 120 to obtain digital diagnostic information. The external device 163 can also be equipped with an operable screen for easy reading of digital diagnostic information.

[0038] A receiving module 130 is also provided inside the optical module. The transmitting port 162 of the external device 163 is connected to the optical module through the receiving end 160. The external device 163 can send a second modulated optical signal to the optical module 140. The second modulated optical signal includes control information for controlling the working state of the optical module. For example, control information for the data type of the digital diagnostic information sent and control information for turning on / off the digital diagnostic information sending, etc. After the receiving module 130 receives the second modulated optical signal, it demodulates the optical signal into an electrical control signal, and the control module 110 performs corresponding control operations according to the electrical control signal, thereby adjusting the working state of the optical module.

[0039] In the technical solution provided by the embodiment of the present invention, the control module controls the light source module to emit the first modulated optical signal according to the digital diagnostic information, transmits the digital diagnostic information of the optical module in the form of an optical signal to the transmitting end of the optical module, and uses the external device to receive and demodulate the first modulated signal, so that the digital diagnostic information of the optical module can be read on the external device. By using the external device to send the second modulated optical signal, after the receiving module receives the second modulated optical signal, it demodulates the optical signal into an electrical control signal, and the control module performs corresponding control operations according to the electrical control signal, thereby adjusting the working state of the optical module. Therefore, during the maintenance of the optical module, there is no need to plug and unplug the optical module, and there is no need to interrupt the service. The digital diagnostic information of the optical module can be quickly read, and the working state of the optical module can be adjusted, improving the diagnostic efficiency and convenience of the optical module.

[0041] Specifically, the plastic optical fiber 210 is an optical fiber made of a light-transmitting polymer, which can be drawn using the polymer, has a relatively low cost, and has a soft structure. Therefore, inside the optical module, the light source module 120 and the transmitting end 150, and the receiving module 130 and the receiving end 160 are respectively connected by the plastic optical fiber 210. Compared with traditional optical fibers, it is easier to wire and avoid damage to the optical fiber line.

[0043] The lens 3 is connected to the plastic optical fiber 210; the lens 3 is used to increase the angle of the signal that can be received or sent by the plastic optical fiber 210.

[0044] Specifically, one end of the plastic optical fiber 210 is connected to the lens 3. The optical signal transmitted by the plastic optical fiber 210 is refracted when output or received through the lens 3, increasing the diffusion angle of the optical signal output / input, thereby increasing the emission and reception angles of the optical signal and reducing signal loss.

[0045] Continue to refer to Figure 4 , the transmitting end 150 and the receiving end 160 further include an optical module cavity 1, and the optical module cavity 1 is used to accommodate part of the lens 3 and the plastic optical fiber 210 connected to the lens 3.

[0046] Specifically, part of the lens 3 is arranged at one end of the optical module cavity 1, and the plastic optical fiber 210 can be inserted into the cavity from the other end, so that the plastic optical fiber 210 is connected to the lens 3. The optical module cavity 1 can protect the connection part and prevent the fiber from being damaged due to excessive bending angle.

[0047] Optionally, the receiving module 130 is a PIN receiver or a photodiode.

[0048] Specifically, both the PIN receiver and the photodiode are optoelectronic conversion devices. When receiving an optical signal, they output a photocurrent.

The light source module 120, the control module 110 and the receiving module 130 can be integrated on the same circuit board, and the transformation can be realized without changing the original optical module structure. Among them, the control module 110 can share the MCU control unit of the optical module, and add the light source module 120 and the receiving module 130 on the original optical module structure, further reducing the complexity of the improvement of the optical module structure and the cost of the optical module.

[0052] Specifically, the information recognition tag 310 can be an electronic information tag, such as QR code information, barcode information, etc., or it can be physical nameplate information. The model number and hardware information of the optical module are engraved on the nameplate, which is convenient for on-site maintenance personnel to quickly obtain the basic information of the optical module.

[0053] Optionally, the light source module 120 includes at least one of an LED and an Oled light source.

[0054] Specifically, at least one of an LED and an OLED light source is used as the light source module 120. The light source module 120 emits a first modulated optical signal according to the first control signal. The LED and the OLED are small in size and high in brightness, which is beneficial to the miniaturization development of the optical module.
