[0034] Hereinafter, some embodiments of the present disclosure will be described clearly and in detail with reference to the accompanying drawings. However, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments provided by the present disclosure fall within the scope of protection of the present disclosure.

[0035] Unless otherwise required by the context, throughout the specification and claims, the term "comprising" is construed in an open, inclusive sense, i.e., "including, but not limited to"; the terms "first" and "second" should not be construed as indicating or implying relative importance or an upper limit on quantity; the term "plurality" means two or more; the term "connected" should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or integrated, can be directly connected, or can be indirectly connected through an intermediate medium; the use of the term "adapted to" or "configured to" implies open and inclusive language, which does not exclude a device adapted to or configured to perform additional tasks or steps; descriptions such as "parallel", "perpendicular", "same", "equal", "consistent", "flush", etc. do not limit to absolute mathematical theory relationships, but also include an acceptable error range in practice, and also include differences formed due to manufacturing reasons based on the same design concept.

[0036] In optical communication technology, in order to establish information transfer between information processing devices, it is necessary to load information onto light and utilize the propagation of light to achieve information transfer. Here, the light loaded with information is an optical signal. When the optical signal is transmitted in an information transmission device, the loss of optical power can be reduced, so high-speed, long-distance, and low-cost information transfer can be achieved. The signals that information processing devices can recognize and process are electrical signals. Information processing devices generally include optical network terminals (Optical Network Unit, ONU), gateways, routers, switches, mobile phones, computers, servers, tablet computers, televisions, etc., and information transmission devices generally include optical fibers and optical waveguides, etc.

[0037] An optical module can realize the mutual conversion between optical signals and electrical signals between an information processing device and an information transmission device. For example, at least one of the optical signal input end or the optical signal output end of the optical module is connected to an optical fiber, and at least one of the electrical signal input end or the electrical signal output end of the optical module is connected to an optical network terminal; the first optical signal from the optical fiber is transmitted to the optical module, the optical module converts the first optical signal into a first electrical signal, and transmits the first electrical signal to the optical network terminal; the second electrical signal from the optical network terminal is transmitted to the optical module, the optical module converts the second electrical signal into a second optical signal, and transmits the second optical signal to the optical fiber. Since information can be transmitted between multiple information processing devices through electrical signals, at least one of the multiple information processing devices needs to be directly connected to the optical module, rather than all information processing devices being directly connected to the optical module. Here, the information processing device directly connected to the optical module is called the host computer of the optical module. In addition, the optical signal input end or the optical signal output end of the optical module can be called an optical port, and the electrical signal input end or the electrical signal output end of the optical module can be called an electrical port.

[0038] Figure 1 Partial structural diagram of an optical communication system according to some embodiments of the present disclosure. As Figure 1 shown, the optical communication system mainly includes a remote information processing device 1000, a local information processing device 2000, a host computer 100, an optical module 200, an optical fiber 101, and a network cable 103.

[0039] One end of the optical fiber 101 extends in the direction of the remote information processing device 1000, and the other end of the optical fiber 101 is connected to the optical module 200 through the optical port of the optical module 200. The optical signal can be totally reflected in the optical fiber 101, and the propagation of the optical signal in the total reflection direction can almost maintain the original optical power. The optical signal undergoes multiple total reflections in the optical fiber 101 to transmit the optical signal from the remote information processing device 1000 to the optical module 200, or to transmit the optical signal from the optical module 200 to the remote information processing device 1000, thereby realizing long-distance and low-power-loss information transmission.

[0040] The optical communication system may include one or more optical fibers 101, and the optical fiber 101 is detachably or fixedly connected to the optical module 200. The host computer 100 is configured to provide a data signal to the optical module 200, receive a data signal from the optical module 200, or monitor or control the working state of the optical module 200.

[0041] The host computer 100 includes a housing substantially in the shape of a cuboid, and an optical module interface 102 provided on the housing. The optical module interface 102 is configured to access the optical module 200 to establish a unidirectional or bidirectional electrical signal connection between the host computer 100 and the optical module 200.

[0042] The host computer 100 further includes an external power interface, which can access an electrical signal network. For example, the external power interface includes a Universal Serial Bus (USB) interface or a network cable interface 104. The network cable interface 104 is configured to access a network cable 103, so that the host computer 100 establishes a unidirectional or bidirectional electrical signal connection with the network cable 103. One end of the network cable 103 is connected to the local information processing device 2000, and the other end of the network cable 103 is connected to the host computer 100, so as to establish an electrical signal connection between the local information processing device 2000 and the host computer 100 through the network cable 103. For example, a third electrical signal sent by the local information processing device 2000 is transmitted into the host computer 100 through the network cable 103. The host computer 100 generates a second electrical signal according to the third electrical signal. The second electrical signal from the host computer 100 is transmitted to the optical module 200. The optical module 200 converts the second electrical signal into a second optical signal and transmits the second optical signal to the optical fiber 101. The second optical signal is transmitted in the optical fiber 101 to the remote information processing device 1000. For example, a first optical signal from the remote information processing device 1000 propagates through the optical fiber 101. The first optical signal from the optical fiber 101 is transmitted to the optical module 200. The optical module 200 converts the first optical signal into a first electrical signal. The optical module 200 transmits the first electrical signal to the host computer 100. The host computer 100 generates a fourth electrical signal according to the first electrical signal and transmits the fourth electrical signal into the local information processing device 2000. It should be noted that the optical module is a tool for realizing the mutual conversion between optical signals and electrical signals. In the above process of converting optical signals and electrical signals, the information does not change, but the encoding and decoding methods of the information may change.

[0043] In addition to including an optical network terminal, the host computer 100 further includes an Optical Line Terminal (OLT), an Optical Network Terminal (ONT), or a data center server, etc.

[0044] Figure 2 It is a partial structure diagram of a host computer according to some embodiments of the present disclosure. To clearly show the connection relationship between the optical module 200 and the host computer 100, Figure 2 only the structure of the host computer 100 related to the optical module 200 is shown. As Figure 2 shown, the host computer 100 further includes a PCB circuit board 105 disposed in the housing, a cage 106 disposed on the surface of the PCB circuit board 105, a radiator 107 disposed on the cage 106, and an electrical connector disposed inside the cage 106. The electrical connector is configured to access the electrical port of the optical module 200; the radiator 107 has raised structures such as fins for increasing the heat dissipation area.

[0045] The optical module 200 is inserted into the cage 106 of the host computer 100, and the cage 106 fixes the optical module 200. The heat generated by the optical module 200 is conducted to the cage 106 and then diffused through the radiator 107. After the optical module 200 is inserted into the cage 106, the electrical port of the optical module 200 is connected to the electrical connector inside the cage 106, so as to establish a two-way electrical signal connection between the optical module 200 and the host computer 100. In addition, the optical port of the optical module 200 is connected to the optical fiber 101, so as to establish a two-way optical signal connection between the optical module 200 and the optical fiber 101.

[0046] Figure 3 It is a structural diagram of an optical module provided according to some embodiments of the present disclosure. Figure 4 It is an exploded view of an optical module provided according to some embodiments of the present disclosure. As Figure 3 and Figure 4 shown, the optical module 200 includes a shell, a circuit board 300 disposed inside the shell, and an optical transceiver component 400.

[0047] The shell includes an upper shell 201 and a lower shell 202. The upper shell 201 covers the lower shell 202 to form the above-mentioned shell having two openings 204 and 205; the outer contour of the shell generally presents a rectangular body.

[0048] In some embodiments, the lower shell 202 includes a bottom plate 2021 and two lower side plates 2022 located on both sides of the bottom plate 2021 and perpendicular to the bottom plate 2021; the upper shell 201 includes a cover plate 2011, and the cover plate 2011 covers the two lower side plates 2022 of the lower shell 202 to form the above-mentioned shell.

[0049] In some embodiments, the lower shell 202 includes a bottom plate 2021 and two lower side plates 2022 located on both sides of the bottom plate 2021 and perpendicular to the bottom plate 2021; the upper shell 201 includes a cover plate 2011 and two upper side plates 2012 located on both sides of the cover plate 2011 and perpendicular to the cover plate 2011. The two upper side plates 2012 are combined with the two lower side plates 2022 to realize the upper shell 201 covering the lower shell 202.

[0050] The direction where the line connecting the two openings 203 and 204 is located may be consistent with the length direction of the optical module 200 or may not be consistent with the length direction of the optical module 200. For example, the opening 203 is located at the end of the optical module 200 ( Figure 3 the right end), and the opening 204 is also located at the end of the optical module 200 ( Figure 3The left end). Alternatively, the opening 203 is located at the end of the optical module 200, and the opening 204 is located at the side of the optical module 200. The opening 203 is an electrical port, and the gold finger of the circuit board 300 extends out from the electrical port and is inserted into the electrical connector of the host computer 100; the opening 204 is an optical port and is configured to access the external optical fiber 101 so that the optical fiber 101 is connected to the optical transceiver component 400 in the optical module 200.

[0051] Adopting the assembly method of combining the upper housing 201 and the lower housing 202 facilitates the installation of the circuit board 300, the optical transceiver component 400, etc. into the above-mentioned housing, and the upper housing 201 and the lower housing 202 can encapsulate and protect the above-mentioned devices. In addition, when assembling the circuit board 300, the optical transceiver component 400, etc., it is convenient for the deployment of the positioning components, heat dissipation components, and electromagnetic shielding components of these devices, which is beneficial to the automated implementation of production.

[0052] In some embodiments, the upper housing 201 and the lower housing 202 are made of metal materials, which is beneficial to achieve electromagnetic shielding and heat dissipation.

[0053] In some embodiments, the optical module 200 further includes an unlocking component 600 located outside its housing. The unlocking component 600 is configured to achieve a fixed connection between the optical module 200 and the host computer, or to release the fixed connection between the optical module 200 and the host computer.

[0054] For example, the unlocking component 600 is located outside the two lower side plates 2022 of the lower housing 202 and includes an engaging component that matches the cage 106 of the host computer 100. When the optical module 200 is inserted into the cage 106, the engaging component of the unlocking component 600 fixes the optical module 200 in the cage 106; when the unlocking component 600 is pulled, the engaging component of the unlocking component 600 moves accordingly, thereby changing the connection relationship between the engaging component and the host computer to release the fixation of the optical module 200 and the host computer, so that the optical module 200 can be withdrawn from the cage 106.

[0055] The circuit board 300 includes circuit traces, electronic components, and chips, etc. The electronic components and chips are connected according to the circuit design through the circuit traces to achieve functions such as power supply, electrical signal transmission, and grounding. The electronic components may include, for example, capacitors, resistors, triodes, and metal-oxide-semiconductor field-effect transistors (MOSFETs). The chips may include, for example, microcontroller units (MCUs), laser driver chips, transimpedance amplifiers (TIAs), limiting amplifiers (LIAs), clock and data recovery chips (CDRs), power management chips, and digital signal processing (DSP) chips.

[0056] The circuit board 300 is generally a rigid circuit board. Due to its relatively hard material, the rigid circuit board can also achieve a bearing function. For example, the rigid circuit board can stably carry the above-mentioned electronic components and chips; the rigid circuit board can also be inserted into the electrical connectors in the cage 106 of the host computer 100.

[0057] The circuit board 300 also includes a gold finger formed on its end surface. The gold finger is composed of a plurality of independent pins. The circuit board 300 is inserted into the cage 106, and the gold finger is electrically connected to the electrical connector in the cage 106. The gold finger can be provided only on the surface of one side of the circuit board 300 (for example, Figure 4 the upper surface shown), or can be provided on the upper and lower surfaces of the circuit board 300 to provide a larger number of pins, so as to adapt to occasions with a large demand for the number of pins. The gold finger is configured to establish an electrical connection with the host computer to achieve functions such as power supply, grounding, inter-integrated circuit (I2C) signal transmission, and data signal transmission. Of course, flexible circuit boards are also used in some optical modules. The flexible circuit board is generally used in cooperation with the rigid circuit board as a supplement to the rigid circuit board.

[0058] In some embodiments, the optical transceiver component 400 includes an optical transmitting component and an optical receiving component. At least one of the optical transmitting component and the optical receiving component is located at the end of the circuit board 300 away from the gold finger.

[0059] In some embodiments, the optical transmitting component or the optical receiving component is physically separated from the circuit board 300, and then electrically connected to the circuit board 300 through the corresponding flexible circuit board or electrical connector respectively.

[0060] In some embodiments, at least one of the light emitting component or the light receiving component may be directly disposed on the circuit board 300. For example, at least one of the light emitting component or the light receiving component may be disposed on the surface of the circuit board 300 or on the side of the circuit board 300.

[0061] In some embodiments, the optical module 200 further includes an adapter group 700. The adapter group 700 is disposed in the optical port. One end of the adapter group 700 is used to dock with the optical fiber 101 (hereinafter referred to as the external optical fiber), and the other end of the adapter group 700 is used to connect to the internal optical fiber to connect the optical transceiver component 400 through the internal optical fiber. Exemplarily, the adapter group 700 includes a plurality of fiber optic adapters. For example, the adapter group 700 includes 4 fiber optic adapters, and the 4 fiber optic adapters are arranged in two rows.

[0062] In some embodiments, the optical module 200 further includes an optical fiber fixing component 800. The optical fiber fixing component 800 is disposed in the optical port. The optical fiber fixing component 800 is connected to the housing, and the optical fiber fixing component 800 is fixedly connected to the adapter group 700 to fix the adapter group 700 at the optical port.

[0063] In some embodiments, the height of one end of the housing is greater than the thickness of the other end of the housing to facilitate the assembly and fixation of the adapter group 700.

The heat dissipation fin group 161 includes a plurality of heat dissipation fins, and there is a gap between adjacent heat dissipation fins. One end of the gap is an inclined surface.

[0071] In some embodiments, the surface of the transition portion 2016 connecting the heat dissipation fin group 161 is an inclined surface, which is inclined from the other end of the transition portion 2016 towards the cover plate 2011, so that one end of the gap between adjacent heat dissipation fins is an inclined surface, to drain the air flow, facilitate the efficient flow of the air flow into the gap, and improve the heat dissipation efficiency of the heat dissipation fin group 161.
