[0042] Next, the technical solutions in some embodiments of the present disclosure will be clearly and detailedly described in conjunction with the accompanying drawings. Obviously, 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 belong to the scope of protection of the present disclosure.

[0043] In optical communication technology, in order to establish information transmission between information processing devices, it is necessary to load information onto light and utilize the propagation of light to achieve information transmission. Here, the light loaded with information is the optical signal. When the optical signal is transmitted in the information transmission device, the loss of optical power can be reduced, so that high-speed, long-distance, and low-cost information transmission can be achieved. The signals that information processing devices can recognize and process are electrical signals. Information processing devices generally include optical network units (ONUs), gateways, routers, switches, mobile phones, computers, servers, tablet computers, televisions, etc., and information transmission devices generally include optical fibers and optical waveguides, etc.

[0044] The optical module can realize the mutual conversion between optical signals and electrical signals between the information processing device and the 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 unit; the first optical signal from the optical fiber is transmitted to the optical module, and the optical module converts the first optical signal into a first electrical signal and transmits the first electrical signal to the optical network unit; the second electrical signal from the optical network unit is transmitted to the optical module, and 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.

[0045] Figure 1 It is a partial structural diagram of an optical communication system provided 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.

[0046] 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.

[0047] The optical communication system may include one or more optical fibers 101, and the optical fibers 101 are 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.

[0048] 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.

[0049] The host computer 100 further includes an external electrical interface, and the external electrical interface can access an electrical signal network. For example, the external electrical interface includes a Universal Serial Bus (USB) interface or a network cable interface 104. The network cable interface 104 is configured to access the network cable 103 to establish a unidirectional or bidirectional electrical signal connection between the host computer 100 and 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 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 conversion process of optical signals and electrical signals, the information does not change, but the encoding and decoding methods of the information may change.

[0050] 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.

[0051] Figure 2 The following is a partial structure diagram of a host computer according to some embodiments. 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 heat sink 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 heat sink 107 has raised structures such as fins to increase the heat dissipation area.

[0052] The optical module 200 is inserted into the cage 106 of the host computer 100, and the optical module 200 is fixed by the cage 106. The heat generated by the optical module 200 is conducted to the cage 106 and then diffused through the heat sink 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.

[0053] Figure 3 The following is a structure diagram of an optical module provided according to some embodiments of the present disclosure, Figure 4 and the following is an exploded view of an optical module provided according to some embodiments of the present disclosure; wherein: the x-axis direction is the length direction of the optical module 200, the y-axis direction is the width direction of the optical module 200, and the z-axis direction is the height direction of the optical module 200. As Figure 3 and Figure 4 shown, the optical module 200 includes a shell, a circuit board 300 disposed in the shell, an optical transmitting component 400, and an optical receiving component 500. However, the present disclosure is not limited thereto. In some embodiments, the optical module 200 includes one of the optical transmitting component 400 and the optical receiving component 500.

[0054] The shell includes an upper shell 201 and a lower shell 202. The upper shell 201 is assembled and connected to the lower shell 202 to form the above-mentioned shell having two openings 203 and 204; the outer contour of the shell generally presents a rectangular body.

[0055] In some embodiments, the lower shell 202 includes a bottom plate 2021 and lower side plates 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 of the lower shell 202 to form the above-mentioned shell.

[0056] In some embodiments, the lower shell 202 includes a bottom plate 2021 and a first lower side plate 2022 and a second lower side plate 2023 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 a first upper side plate 2012 and a second upper side plate 2013 located on both sides of the cover plate 2011 and perpendicular to the cover plate 2011, and the first lower side plate 2022 and the second lower side plate 2023 are respectively connected to the first upper side plate 2012 and the second upper side plate 2013 to realize the assembly connection between the upper shell 201 and the lower shell 202.

[0057] The direction of the line connecting the two openings 203 and 204 may be consistent with the length direction of the optical module 200, or may be inconsistent 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 opening 204 is also located at the end of the optical module 200 ( Figure 3 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 from the electrical port and is inserted into the host computer (for example, the optical network terminal 100); the opening 204 is an optical port, which is configured to access the optical fiber 101 so that the optical fiber 101 is connected to the optical module 200.

[0058] The assembly method of combining the upper shell 201 and the lower shell 202 facilitates the installation of components such as the circuit board 300, the light emitting component 400 and the light receiving component 500 into the shell, and the upper shell 201 and the lower shell 202 form a package protection for these components. In addition, when assembling components such as the circuit board 300, the light emitting component 400 and the light receiving component 500, it is convenient to deploy the positioning components, heat dissipation components and electromagnetic shielding components of these components, which is conducive to the automated implementation of production.

[0059] In some embodiments, the upper shell 201 and the lower shell 202 are made of metal materials to facilitate electromagnetic shielding and heat dissipation.

[0060] In some embodiments, the optical module 200 further includes an unlocking component 600 located outside its housing, and 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.

[0061] For example, engaging components are provided on the lower housing 202. The engaging components are used to fix the optical module 200 in the cage 106. The unlocking component 600 is provided on the lower housing 202. When the unlocking component 600 is pulled, the unlocking component 600 moves, and the unlocking component 600 changes the connection relationship between the engaging component and the host computer, so as to release the fixation of the optical module 200 to the host computer, and thus the optical module 200 can be withdrawn from the cage 106.

[0062] The circuit board 300 includes circuit traces, electronic components and chips. The electronic components and chips are connected together according to the circuit design through the circuit traces to achieve functions such as power supply, electrical signal transmission and grounding. The electronic components include, for example, capacitors, resistors, triodes, metal-oxide-semiconductor field-effect transistors (MOSFETs). The chips include, for example, lasers, photodetectors, microcontroller units (MCUs), laser driver chips, limiting amplifiers (LAs), clock and data recovery (CDR) chips, power management chips, digital signal processing (DSP) chips, etc.

[0063] 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 bear 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.

[0064] The circuit board 300 further 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.

[0065] In some embodiments, the light emitting component 400 and the light receiving component 500 are physically separated from the circuit board 300 respectively, and then are electrically connected to the circuit board 300 through corresponding flexible circuit boards or electrical connectors respectively. Of course, in some embodiments, at least one of the light emitting component 400 and the light receiving component 500 can be directly disposed on the circuit board 300. For example, at least one of the light emitting component 400 or the light receiving component 500 can be disposed on the surface of the circuit board 300 or on the side of the circuit board 300.

[0066] In some embodiments, the optical module 200 further includes a first optical fiber adapter 410 and a second optical fiber adapter 510, and the first optical fiber adapter 410 and the second optical fiber adapter 510 are used to connect to an external optical fiber 101.

As Figure 5 shown, the unlocking component 600 includes a holding portion 610, a connecting portion 620, an assembling portion 630, and an unlocking portion 640. The holding portion 610 is one end of the unlocking component 600, and the unlocking portion 640 is the other end of the unlocking component 600. The holding portion 610 and the unlocking portion 640 are sequentially connected through the connecting portion 620 and the assembling portion 630. One end of the connecting portion 620 is connected to the holding portion 610, the other end of the connecting portion 620 is connected to one end of the assembling portion 630, and the other end of the assembling portion 630 is connected to the unlocking portion 640. The holding portion 610 is used for convenient holding when pulling the unlocking component 600; the connecting portion 620 is used to realize the connection from the holding portion 610 to the assembling portion 630, so as to facilitate the adjustment of the length of the unlocking component 600; the assembling portion 630 is used for assembling and connecting to the lower housing 202 to realize the assembly and fixation of the unlocking component 600 and the lower housing 202 and the unlocking component 600 can move relative to the lower housing 202; the unlocking portion 640 is used to release the connection relationship between the engaging component and the host computer when pulling the unlocking component 600.

[0068] In some embodiments, the unlocking component 600 is integrally formed of a plastic material, which is convenient for saving the production cost of the unlocking component 600.

[0069] In some embodiments, the width of the holding portion 610 is greater than the width of the connecting portion 620, which is convenient for the holding portion 610 to be held. Exemplarily, a through hole 611 is provided on the holding portion 610, which is more convenient for the holding portion 610 to be held.

[0070] In some embodiments, the connecting portion 620 has a preset length to control the overall length of the unlocking component 600, facilitating the installation of the optical module 200 into the cage 106 that is relatively far from the edge of the host computer. Exemplarily, a through hole 621 is provided on the connecting portion 620. The through hole 621 extends along the length direction of the connecting portion 620. The through hole 621 can increase the elasticity of the connecting portion 620, facilitating the avoidance of the connector of the external optical fiber 101 when the optical module 200 is connected to the external optical fiber 101.

[0071] In some embodiments, the thickness of the assembling portion 630 is greater than the thickness of the connecting portion 620, facilitating an increase in the assembling strength between the assembling portion 630 and the lower housing 202. Exemplarily, an assembling part is formed on the assembling portion 630, and an assembling mechanism is provided on the lower housing 202. The assembling part is assembled and connected to the assembling mechanism, enabling the assembling portion 630 to move relative to the lower housing 202.

One end of the assembling body 630a is connected to the connecting portion 620, and the other end of the assembling body 630a is connected to the unlocking portion 640. A first assembling part 631 is provided on one side of the assembling body 630a, and a second assembling part 632 is provided on the other side of the assembling body 630a, facilitating the smooth assembling and connection of the assembling body 630a to the lower housing 202.

[0074] In some embodiments, the first fitting 631 and the second fitting 632 respectively include an assembly post and a limiting protrusion, and the limiting protrusion is arranged on the assembly post; the assembly post is used for guiding and limiting, and the limiting protrusion is used for limiting, so that the assembly body 630a connected by the first fitting 631 and the second fitting 632 can move relative to the lower housing 202. Exemplarily, an assembly mechanism corresponding to the assembly post and the limiting protrusion is arranged on the lower housing 202, and the assembly mechanism is assembled and connected to the assembly post and the limiting protrusion. The assembly mechanism can be structures such as a sliding groove and a sliding rail.
