[0137] The embodiments of this disclosure will now be described clearly and in detail with reference to the accompanying drawings. However, the described embodiments are merely some, and not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments provided in this disclosure are within the scope of protection of this disclosure.

[0138] Unless the context otherwise requires, throughout the specification and claims, the term "comprising" is interpreted as open and inclusive, meaning "including, but not limited to"; the terms "first" and "second" should not be construed as indicating or implying relative importance or indicating an upper limit on the number; the term "multiple" means two or more; the term "connection" should be interpreted broadly, for example, "connection" can be a fixed connection, a detachable connection, or an integral part, and can be a direct connection or an indirect connection through an intermediate medium; the use of the terms "applicable to" or "configured to" implies open and inclusive language, which does not exclude applicability to or configuration to devices performing additional tasks or steps; descriptions such as "parallel," "perpendicular," "identical," "consistent," and "aligned" are not limited to absolute mathematical theoretical relationships, but also include acceptable error ranges arising in practice, and differences based on the same design concept but due to manufacturing reasons.

[0139] In optical communication technology, to establish information transmission between information processing devices, information needs to be loaded onto light, and the propagation of light is used to transmit the information. Here, the light carrying the information is called an optical signal. When optical signals are transmitted in information transmission equipment, optical power loss can be reduced, thus enabling high-speed, long-distance, and low-cost information transmission. Information processing devices can recognize and process electrical signals. Information processing devices typically include optical network units (ONUs), gateways, routers, switches, mobile phones, computers, servers, tablets, televisions, etc., while information transmission equipment typically includes optical fibers and optical waveguides.

[0140] An optical module enables the conversion between optical and electrical signals between information processing and transmission devices. For example, at least one of the optical signal input or output ports of the optical module is connected to an optical fiber, and at least one of the electrical signal input or output ports is connected to an optical network terminal. A first optical signal from the optical fiber is transmitted to the optical module, which converts it into a first electrical signal and transmits it to the optical network terminal. A second electrical signal from the optical network terminal is transmitted to the optical module, which converts it into a second optical signal and transmits it back to the optical fiber. Since multiple information processing devices can transmit information via electrical signals, at least one of the devices needs to be directly connected to the optical module, rather than all devices. Here, the information processing device directly connected to the optical module is referred to as the host computer of the optical module. Furthermore, the optical signal input or output port of the optical module can be referred to as an optical port, and the electrical signal input or output port can be referred to as an electrical port.

[0141] Figure 1 This is a partial structural diagram of an optical communication system according to some embodiments. Figure 1 As 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.

[0142] One end of optical fiber 101 extends toward the remote information processing device 1000, and the other end of optical fiber 101 is connected to optical module 200 through the optical port of optical module 200. The optical signal can undergo total internal reflection in optical fiber 101, and the propagation of the optical signal in the direction of total internal reflection can almost maintain the original optical power. The optical signal undergoes multiple total internal reflections in optical fiber 101 to transmit the optical signal from the remote information processing device 1000 to optical module 200, or to transmit the optical signal from optical module 200 to remote information processing device 1000, thereby realizing long-distance, low-power loss information transmission.

[0143] The optical communication system may include one or more optical fibers 101, and the optical fibers 101 may be detachably or fixedly connected to the optical module 200. The host computer 100 is configured to provide data signals to the optical module 200, receive data signals from the optical module 200, or monitor or control the operating status of the optical module 200.

[0144] The host computer 100 includes a generally rectangular housing and an optical module interface 102 disposed on the housing. The optical module interface 102 is configured to connect to the optical module 200 so that the host computer 100 and the optical module 200 can establish a one-way or two-way electrical signal connection.

[0145] The host computer 100 also includes an external power interface that can connect to an electrical signal network. For example, this external power interface includes a Universal Serial Bus (USB) interface or a network cable interface 104, which is configured to connect a 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, thereby establishing an electrical signal connection between the local information processing device 2000 and the host computer 100 via the network cable 103. For example, a third electrical signal emitted by the local information processing device 2000 is transmitted to the host computer 100 via the network cable 103. The host computer 100 generates a second electrical signal based on the third electrical signal. This second electrical signal from the host computer 100 is transmitted to the optical module 200, which converts the second electrical signal into a second optical signal and transmits it to the optical fiber 101. The second optical signal is then transmitted in the optical fiber 101 to the remote information processing device 1000. Alternatively, a first optical signal from the remote information processing device 1000 propagates through the optical fiber 101 and is transmitted to the optical module 200. The optical module 200 converts the first optical signal into a first electrical signal and transmits it to the host computer 100. The host computer 100 generates a fourth electrical signal based on the first electrical signal and transmits the fourth electrical signal to the local information processing device 2000. It should be noted that an optical module is a tool for converting optical signals to electrical signals. During the conversion process, the information itself does not change, but the encoding and decoding methods can change.

[0146] In addition to optical network terminals, the host computer 100 also includes optical line terminals (OLTs), optical network equipment (ONTs), or data center servers.

[0147] Figure 2 This is a partial structural 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. For example... Figure 2 As shown, the host computer 100 also includes a PCB circuit board 105 disposed within 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 connect to the electrical port of the optical module 200; the heat sink 107 has fins and other protruding structures to increase the heat dissipation area.

[0148] The optical module 200 is inserted into the cage 106 of the host computer 100, where it is secured. Heat generated by the optical module 200 is conducted to the cage 106 and then dissipated through the heat sink 107. After insertion into the cage 106, the optical module 200's electrical port connects to the electrical connector inside the cage 106, establishing a bidirectional electrical signal connection between the optical module 200 and the host computer 100. Furthermore, the optical port of the optical module 200 connects to the optical fiber 101, establishing a bidirectional optical signal connection between the optical module 200 and the optical fiber 101.

[0149] Figure 3 This is a structural diagram of an optical module according to some embodiments. Figure 4 This is an exploded view of an optical module according to some embodiments. Figure 5 This is an exploded structural diagram of an optical module according to some embodiments. For example... Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, the optical module 200 includes a shell, which comprises an upper shell 201 and a lower shell 202. The upper shell 201 covers the lower shell 202, forming two openings 204 and 205, one of which is an electrical port and the other is an optical port. In some embodiments, the shell forms an opening that serves as both an electrical port and an optical port.

[0150] In some embodiments, the upper housing 201 and the lower housing 202 are made of metal materials, which facilitates electromagnetic shielding and heat dissipation.

[0151] The assembly method of combining the upper housing 201 and the lower housing 202 facilitates the installation of circuit boards 300 and other components into the housing. The upper housing 201 and the lower housing 202 can encapsulate and protect the aforementioned devices.

[0152] The direction of the line connecting the two openings 204 and 205 can be consistent with or inconsistent with the length direction of the optical module 200. For example, opening 204 is located at the end of the optical module 200. Figure 3 The opening 205 is also located at the end of the optical module 200 (right end). Figure 3 (The left end). Alternatively, opening 204 is located at the end of optical module 200, while opening 205 is located on the side of optical module 200.

[0153] In some embodiments, the lower housing 202 includes a base plate 2021 and two lower side plates 2022 located on both sides of the base plate 2021 and perpendicular to the base plate 2021; the upper housing 201 includes a cover plate 2011, which covers the two lower side plates 2022 of the lower housing 202 to form the aforementioned housing.

[0154] In some embodiments, the lower housing 202 includes a base plate 2021 and two lower side plates 2022 located on both sides of the base plate 2021 and perpendicular to the base plate 2021; the upper housing 201 includes a cover plate 2011 and two upper side plates located on both sides of the cover plate 2011 and perpendicular to the cover plate 2011. The two upper side plates and the two lower side plates 2022 are combined to realize that the upper housing 201 covers the lower housing 202.

[0155] like Figure 3 and Figure 4 As shown, in some embodiments, the optical module includes a circuit board 300 disposed within a housing. 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 realize functions such as power supply, electrical signal transmission, and grounding. Electronic components may include, for example, capacitors, resistors, transistors, and metal-oxide-semiconductor field-effect transistors (MOSFETs). Chips may include microcontroller units (MCUs), laser driver chips, transimpedance amplifiers (TIAs), limiting amplifiers (LAs), clock and data recovery chips (CDRs), power management chips, and digital signal processing (DSP) chips.

[0156] In some embodiments, the circuit board includes a rigid circuit board, which, due to its relatively rigid material, can also serve a load-bearing function, such as being able to stably support the aforementioned electronic components and chips; the rigid circuit board can also be inserted into an electrical connector in the cage 106 of the host computer 100.

[0157] In some embodiments, the circuit board further includes a flexible circuit board, which can be used independently or in conjunction with a rigid circuit board.

[0158] In some embodiments, the circuit board further includes gold fingers formed on its end surface, the gold fingers consisting of a plurality of independent pins.

[0159] In some implementations, the gold fingers 301 are disposed on one side of the surface of the circuit board 300 (e.g., Figure 4 (as shown on the upper surface); In some implementations, the gold fingers 301 are disposed on the upper and lower surfaces of the circuit board 300 to provide a greater number of pins, thereby adapting to situations where the number of pins is required.

[0160] In some implementations, the gold fingers of the circuit board extend from the opening 204 and are inserted into the electrical connector of the host computer 100; the circuit board is inserted into the cage 106, and the gold fingers 301 are connected to the electrical connector inside the cage 106. The gold fingers 301 are configured to establish an electrical connection with the host computer, enabling electrical connection functions such as power supply, grounding, two-wire synchronous serial (Inter-Integrated Circuit, I2C) signal transmission, and data signal transmission.

[0161] In some embodiments, the optical module 200 further includes an unlocking component 600 located outside its housing. The unlocking component 600 is configured to establish 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.

[0162] For example, the unlocking component 600 is located on the outside of the two lower side plates 2022 of the lower housing 202, and includes a locking component that matches the cage 106 of the host computer 100. When the optical module 200 is inserted into the cage 106, the locking component of the unlocking component 600 fixes the optical module 200 in the cage 106; when the unlocking component 600 is pulled, the locking component of the unlocking component 600 moves accordingly, thereby changing the connection relationship between the locking component and the host computer, so as to release the fixation between the optical module 200 and the host computer, thereby allowing the optical module 200 to be pulled out of the cage 106.

[0163] In some embodiments, opening 205 is an optical port, and an optical fiber adapter 700 is provided at opening 205. The optical fiber adapter 700 can establish an optical connection between the internal optical fiber and the external optical fiber of the optical module 200. The optical fiber adapter 700 can provide certain support and protection for the internal optical fiber and the external optical fiber of the optical module 200.

[0164] Figure 6a This is a diagram of a circuit board upper surface assembly structure according to some embodiments. For example... Figure 6a As shown, in some embodiments, a first through hole 302 and a second through hole 303 are formed on the surface of the circuit board 300.

[0165] In some embodiments, the optical module 200 may include a first optical emitting component 400a and a second optical emitting component 400b to improve the transmission rate. The first optical emitting component 400a is embedded in a first through-hole 302, and the second optical emitting component 400b is embedded in a second through-hole 303.

[0166] In some embodiments, the first light emitting component 400a and the second light emitting component 400b are located on the upper surface of the circuit board 300.

[0167] In some embodiments, the optical module 200 may include a base 500f. The upper surface of the base 500f is used to support the first light emitting component 400a and the second light emitting component 400b. Exemplarily, the upper surface of the base 500f faces the upper surface of the circuit board 300, so that the first light emitting component 400a and the second light emitting component 400b face the upper surface of the circuit board 300.

[0168] In some embodiments, the optical module 200 may include a first cover plate 400c, which covers the surface of the circuit board 300. The first cover plate 400c and the surface of the circuit board 300 form a receiving cavity to accommodate the first light emitting component 400a and the second light emitting component 400b.

[0169] In some embodiments, the first optical emitting component 400a is connected to a first optical fiber strip 400d, and the second optical emitting component 400b is connected to a second optical fiber strip 400e. The first optical fiber strip 400d and the second optical fiber strip 400e are respectively connected to the optical fiber adapter 700.

[0170] Figure 6b This is a diagram of a circuit board lower surface assembly structure according to some embodiments. For example... Figure 6b As shown, in some embodiments, the lower surface of the base 500f extends beyond the surface of the circuit board 300.

[0171] In some embodiments, the optical module 200 may include a first light receiving component 500a and a second light receiving component 500b. The first light receiving component 500a and the second light receiving component 500b are located on the lower surface of the circuit board 300. Exemplarily, the first light receiving component 500a and the second light receiving component 500b are disposed on the lower surface of the base 500f.

[0172] In some embodiments, the optical module 200 may include a second cover plate 500c. The base 500f includes a enclosure portion 530f. One end of the second cover plate 500c is disposed on the surface of the base 500f body, and the other end is disposed on the surface of the enclosure portion 530f. The first light receiving component 500a and the second light receiving component 500b are located within the enclosed cavity formed by the second cover plate 500c and the enclosure portion 530f, thereby preventing the cooling medium from entering the interior of the first light receiving component and the second light receiving component during liquid cooling heat dissipation and affecting their optical paths.

[0173] In some embodiments, the enclosure portion 530f rests on the surface of the circuit board 300, exposing the surface of the circuit board 300 enclosed by the enclosure portion 530f, thereby positioning the first light receiving chip array and the second light receiving chip array on the surface of the circuit board enclosed by the enclosure portion 330f. The enclosure portion 530f is formed on one side of the first light receiving component 500a and the second light receiving component 500b. The enclosure portion 530f can be a C-shaped frame. The enclosure portion 530f encloses the first light receiving component 500a and the second light receiving component 500b and supports the second cover plate 500c, such that the second cover plate 500c covers the surfaces of the first light receiving component 500a and the second light receiving component 500b, preventing cooling medium from entering the first light receiving component 500a and the second light receiving component 500b and affecting their optical path.

[0174] Figure 7 This is an exploded view of a circuit board and base assembly according to some embodiments. Figure 7 As shown, in some embodiments, a first through hole 302 and a second through hole 303 are formed on the surface of the circuit board 300. The first through hole 302 and the second through hole 303 are independent of each other and are not connected, so as to retain the wiring space on the surface of the circuit board 300 between the first through hole 302 and the second through hole 303.

[0175] In some embodiments, the top surface of the base 500f is formed with a first boss surface 510f and a second boss surface 520f. The first boss surface 510f extends into the first through hole 302, and the second boss surface 520f extends into the second through hole 303, thereby embedding the base 500f onto the circuit board 300.

[0176] In some embodiments, the first boss surface 510f supports the first light emitting component 400a, and the second boss surface 520f supports the second light emitting component 400b. The first boss surface 510f extends into the first through hole 302, thereby aligning the first light emitting component 400a towards the upper surface of the circuit board 300. The second boss surface 520f extends into the second through hole 303, thereby aligning the second light emitting component 400b towards the upper surface of the circuit board 300. The base 500f has excellent heat dissipation characteristics, and can conduct heat generated by the first light emitting component 400a and the second light emitting component 400b.

[0177] Figure 8a This is an assembly diagram of a base, a first light emitting component, and a second light emitting component according to some embodiments. Figure 8b This is an exploded view of an assembly of a base, a first light-emitting component, and a second light-emitting component according to some embodiments. Figure 8a and Figure 8bAs shown, in some embodiments, the first light emitting component 400a is embedded in the first through hole 302 by the base 500f, and the second light emitting component 400b is embedded in the second through hole 303 by the base 500f.

[0178] In some embodiments, the first optical emitting component 400a may include a first laser 401a. The first optical emitting component 400a may include a first lens 402a. The first optical emitting component 400a may include a first isolator 403a. The first optical emitting component 400a may include a first optical modulation chip 404a. The first optical emitting component 400a may include a first fiber array 405a. The first optical emitting component 400a may include a first modulation driver chip 406a.

[0179] In some embodiments, the first optical modulation chip 404a has an input optical port and multiple output optical ports on its end face. The multiple output optical ports output the same wavelength, thus the first optical modulation chip 404a can internally modulate an input beam of light without a signal to generate multiple optical signals with the same wavelength. The input optical port faces the first laser 401a to receive the beam of light without a signal output from the first laser 401a. The output optical ports face the first fiber array 405a to couple the multiple optical signals modulated by the first optical modulation chip 404a to the first fiber array 405a and output them through the first fiber array 405a.

[0180] In some embodiments, the input waveguide and output waveguide of the first optical modulation chip 404a are not perpendicular to the end face of the first optical modulation chip 404a, thereby preventing the optical signal from being reflected at the end face of the first optical modulation chip 404a. The input end face of the first fiber array 405a is set as an inclined surface, thereby preventing the optical signal from being reflected at the input end face of the first fiber array 405a.

[0181] In some embodiments, the second optical emitting component 400b may include a second laser 401b. The second optical emitting component 400b may include a second lens 402b. The second optical emitting component 400b may include a second isolator 403b. The second optical emitting component 400b may include a second optical modulation chip 404b. The second optical emitting component 400b may include a second fiber array 405b. The second optical emitting component 400b may include a second modulation driver chip 406b. For an optical path description, refer to the first optical emitting component 400a.

[0182] In some embodiments, the second protrusion surface 520f may include a first supporting surface 521f. The first supporting surface 521f supports a second laser 401b, a second lens 402b, a second isolator 403b, and a second fiber array 405b. The second protrusion surface 520f may include a second supporting surface 522f. The second supporting surface 522f supports a second optical modulation chip 404b. The second protrusion surface 520f may include a third supporting surface 523f. The third supporting surface 523f supports a second modulation driver chip 406b.

[0183] Figure 9 This is a cross-sectional view of an assembly of a base, a first light receiving component, and a second light receiving component according to some embodiments. Figure 9 As shown, in some embodiments, the bottom surface of the base 500f carries optical devices, so both the top and bottom surfaces of the base 500f carry optical devices, making full use of the base 500f.

[0184] In some embodiments, the first optical receiving component 500a may include a first refractive element 510a.

The first optical receiving component 500a may include a first TIA 540a. The first refractive element 510a includes an optical fiber extending toward the first optical receiving chip array 530a. A reflective end face is formed at the end of the optical fiber, above the first optical receiving chip array 530a. The reflective end face is used to reflect and change the transmission direction of the optical signal transmitted through the optical fiber, thereby reflecting the optical signal transmitted through the optical fiber to the first optical receiving chip array 530a, achieving optical path reversal. The first optical receiving chip array 530a converts the optical signal into a photocurrent signal, and the first TIA 540a converts the photocurrent signal into a photovoltage signal and amplifies the photovoltage signal.

[0185] In some embodiments, the second light receiving component 500b may include a second refractive element 510b. The second light receiving component 500b may include a second converging lens 520b. The second light receiving component 500b may include a second light receiving chip array 530b.

[0186] In some embodiments, the first optical receiving component 500a is connected to a third optical fiber strip 500d, and the second optical receiving component 500b is connected to a fourth optical fiber strip 500e. The third optical fiber strip 500d and the fourth optical fiber strip 500e are respectively connected to the optical fiber adapter 700.

[0187] In some embodiments, a second cover plate 500c is coated on the surfaces of the first light receiving component 500a and the second light receiving component 500b. The second cover plate 500c can extend along the surfaces of the first light receiving component 500a and the second light receiving component 500b and bend toward the surface of the circuit board 300 to cover and wrap the first light receiving component 500a and the second light receiving component 500b, preventing the cooling medium from entering the first light receiving component 500a and the second light receiving component 500b and affecting their optical path.

[0188] In some embodiments, an embedding groove 940f is formed along the bottom surface of the base 500f body structure and the bottom surface of the enclosure portion 530f to embed the second cover plate 500c into the surface of the base 500f body structure and the enclosure portion 530f, thereby fixing the second cover plate 500c to the bottom surface of the base 500f. The embedding groove 940 is shaped to fit the second cover plate 500c to fix the second cover plate 500c to the base 500f.

[0189] Figure 10 This is a schematic diagram of a fiber optic adapter connection according to some embodiments. Figure 10 As shown, in some embodiments, the optical module may include a fiber optic adapter 700, providing space for coupling connections of optical signals inside and outside the optical module. The fiber optic adapter 700 can provide mechanical support and assembly interfaces.

[0190] In some embodiments, the fiber optic adapter 700 is located at the optical port of the optical module and is assembled in the cavity formed by the upper housing 201 and the lower housing 202.

[0191] In some embodiments, a shielding plate 3000 is provided between the fiber optic adapter 700 and the circuit board 300 to effectively reduce the leakage of high-frequency electromagnetic signals and lower the power consumption of the optical module. Simultaneously, it suppresses external electromagnetic interference. Exemplarily, a first through-hole 3001 and a second through-hole 3002 are formed on the surface of the shielding plate 3000. A first fiber ribbon 400d and a third fiber ribbon 500d pass through the first through-hole 3001 and are connected to the first fiber optic ferrule 910a, while a second fiber ribbon 400e and a fourth fiber ribbon 500e pass through the second through-hole 3002 and are connected to the second fiber optic ferrule 910b.

[0193] In some embodiments, the fiber optic adapter 700 has a first interface 710 at one end facing the outside of the optical module, and a second interface 721 and a third interface 722 at the other end facing the inside of the optical module. The second interface 721 and the third interface 722 are arranged vertically.

[0194] In some embodiments, the optical module may include a first fiber optic connector 800a and a second fiber optic connector 800b, which are stacked one on top of the other. The first fiber optic connector 800a is connected to an external optical fiber, and the second fiber optic connector 800b is also connected to an external optical fiber.

[0195] In some embodiments, the optical module may include a first ferrule assembly 900a and a second ferrule assembly 900b, which are stacked one on top of the other. The first ferrule assembly 900a is connected to the optical fiber ribbon inside the optical module, and the second ferrule assembly 900b is connected to the optical fiber ribbon inside the optical module.

[0196] In some embodiments, the first interface 710 serves as an assembly interface for the first fiber optic connector 800a and the second fiber optic connector 800b to access. The second interface 721 and the third interface 722 serve as assembly interfaces for the first ferrule assembly 900a and the second ferrule assembly 900b to access, respectively. Since the third interface 722 is located below the second interface 721, the second ferrule assembly 900b is located below the first ferrule assembly 900a.

[0197] In some embodiments, the first ferrule assembly 900a and the second ferrule assembly 900b are arranged vertically, which effectively reduces space occupation and makes the structure more compact; at the same time, it is beneficial to make optical connections with fiber optic ribbons of different directions or heights, and improves the applicability of fiber optic adapters.

[0198] In some embodiments, the first fiber optic connector 800a and the first ferrule assembly 900a are respectively assembled into the fiber optic adapter 700 along both sides. The fiber optic adapter 700 provides mechanical support for the first fiber optic connector 800a and the first ferrule assembly 900a, enabling them to achieve optical coupling connection within the fiber optic adapter 700 and establish an internal and external optical signal transmission channel. Similarly, the second fiber optic connector 800b and the second ferrule assembly 900b are respectively assembled into the fiber optic adapter 700 along both sides. The fiber optic adapter 700 provides mechanical support for the second fiber optic connector 800b and the second ferrule assembly 900b, enabling them to achieve optical coupling connection within the fiber optic adapter 700 and establish an internal and external optical signal transmission channel.

[0199] In some embodiments, the two ends of the fiber optic adapter 700 provide assembly interfaces for the first fiber optic connector 800a and the first ferrule assembly 900a, respectively, so that the first fiber optic connector 800a and the first ferrule assembly 900a can be optically mated inside the fiber optic adapter 700, realizing the coupling connection of optical signals inside and outside the optical module. The fiber optic adapter 700, as a connecting component, also constrains the first fiber optic connector 800a and the first ferrule assembly 900a, preventing them from loosening or falling off due to external forces.

[0200] In some embodiments, the first ferrule assembly 900a may include a first fiber optic ferrule 910a. The second ferrule assembly 900b may include a second fiber optic ferrule 910b. The first fiber optic ferrule 910a and the second fiber optic ferrule 910b are respectively used to fix the internal fiber optic ribbon.

[0201] In some embodiments, the first fiber optic ferrule 910a is used to fix the first fiber optic strip 400d and the third fiber optic strip 500d. The second fiber optic ferrule 910b is used to fix the second fiber optic strip 400e and the fourth fiber optic strip 500e.

[0202] In some embodiments, the first fiber optic ferrule 910a and the first fiber optic connector 800a are respectively inserted into the fiber optic adapter 700 from both sides, with their ends facing each other. Then, the first fiber optic ribbon 400d and the third fiber optic ribbon 500d are optically coupled to the external fiber optic cable connected to the first fiber optic connector 800a, realizing the connection between internal and external optical signals. The optical signal emitted by the first optical transmitting component 400a is output to the outside through the external fiber optic cable connected to the first fiber optic connector 800a, and the optical signal from the outside is transmitted to the first optical receiving component 500a through the external fiber optic cable connected to the first fiber optic connector 800a.

[0203] In some embodiments, the second fiber optic ferrule 910b and the second fiber optic connector 800b are respectively inserted into the fiber optic adapter 700 from both sides, with their ends facing each other. Then, the second fiber optic ribbon 400e and the fourth fiber optic ribbon 500e are optically coupled to the external fiber optic cable connected to the second fiber optic connector 800b, respectively, to achieve internal and external optical signal connection. The optical signal emitted by the second optical transmitting component 400b is output to the outside through the external fiber optic cable connected to the second fiber optic connector 800b, and the optical signal from the outside is transmitted to the second optical receiving component 500b through the external fiber optic cable connected to the second fiber optic connector 800b.

[0204] In some embodiments, the first fiber optic ferrule 910a and the second fiber optic ferrule 910b are arranged vertically, which facilitates fiber optic connection with fibers of different heights and reduces fiber optic crossover wiring. This also reduces signal crosstalk between the first optical transmitting component 400a and the second optical transmitting component 400b, as well as between the first optical receiving component 500a and the second optical receiving component 500b.

[0205] In some embodiments, the fiber optic adapter 700 is located at the optical port position, and internal and external optical signals are connected inside the fiber optic adapter 700, thereby establishing an internal and external optical signal transmission channel for the optical module.

[0206] In some embodiments, the fiber optic adapter 700 may include a top surface 730. The top surface 730 faces the upper housing 201. The top surface 730 is formed with a first limiting portion 731 and a first snap-fit ​​portion 732 to achieve a limiting connection with the upper housing 201.

[0207] In some embodiments, the fiber optic adapter 700 may include a side surface 740. The side surface 740 is connected to the top surface 730. The side surface 740 may have a first mounting hole 741 and a second mounting hole 742 formed near the first interface 710.

[0208] In some embodiments, the fiber optic adapter 700 may include a bottom surface 750. The bottom surface 750 faces the lower housing 202 and is positioned relative to the lower housing 202. The bottom surface 750 is disposed opposite to the top surface 730.

[0209] In some embodiments, a first latch 801a is formed on the side of the first fiber optic connector 800a, and a second latch 801b is formed on the side of the second fiber optic connector 800b. Exemplarily, the first latch 801a and the second latch 801b can be elastic latches. When assembling the first fiber optic connector 800a, the first latch 801a, under the action of elastic deformation, is assembled into the first assembly hole 741, fixing the first fiber optic connector 800a within the first interface 710 to prevent loosening or detachment. Similarly, the second latch 801b, under the action of elastic deformation, is assembled into the second assembly hole 742, fixing the second fiber optic connector 800b within the first interface 710 to prevent loosening or detachment. By pressing the first latch 801a and the second latch 801b, the first fiber optic connector 800a and the second fiber optic connector 800b can be detached from the fiber optic adapter 700 and released.

[0210] In some embodiments, a first pin 802a extends from the end face of the first fiber optic connector 800a facing the first fiber optic ferrule 910a, and a second pin 911a extends from the end face of the first fiber optic connector 800a facing the first fiber optic connector 800a. Inside the first fiber optic ferrule 910a, a spring is wrapped around the outer surface of the second pin 911a, with one end of the spring fixed to the surface of the first fiber optic ferrule 910a. When the first fiber optic connector 800a and the first fiber optic ferrule 910a are mated and assembled, the end face of the first pin 802a pushes the end face of the second pin 911a, forcing the second pin 911a to retract axially, and the spring is compressed. The spring force ensures a tight fit between the end faces of the first pin 802a and the second pin 911a, while avoiding excessive pressure that could cause end face wear.

[0211] Figure 12 This is a cross-sectional assembly diagram of a fiber optic adapter according to some embodiments. For example... Figure 12 As shown, in some embodiments, one end of the fiber optic adapter 700 is provided with a second interface 721 and a third interface 722 for assembly and connection of the first ferrule assembly 900a and the second ferrule assembly 900b, respectively.

[0212] In some embodiments, the first ferrule assembly 900a and the second ferrule assembly 900b are arranged vertically, effectively reducing space occupation and resulting in a more compact structure. Simultaneously, the vertical arrangement of the first ferrule assembly 900a and the second ferrule assembly 900b facilitates connection with optical fibers of different directions or heights, improving the applicability of the fiber optic adapter 700. Exemplarily, the second interface 721 is located above the third interface 722, and the first fiber optic ferrule 910a is located above the second fiber optic ferrule 910b. The second interface 721 is used to accommodate the first ferrule assembly 900a. Exemplarily, the first ferrule assembly 900a is connected to the second interface 721. The third interface 722 is used to accommodate the second ferrule assembly 900b. Exemplarily, the second ferrule assembly 900b is connected to the third interface 722.

[0213] In some embodiments, the first optical emitting component 400a and the first optical receiving component 500a are respectively connected to the first optical fiber ferrule 910a, and the second optical emitting component 400b and the second optical receiving component 500b are respectively connected to the second optical fiber ferrule 910b, thereby reducing signal crosstalk. As a result, the optical module 200 can achieve optical connection with external optical fibers through the optical fiber adapter 700.

[0214] In some embodiments, the second interface 721 and the third interface 722 are vertically distributed, with the third interface 722 located below the second interface 721, thereby forming a double-layer insertion channel for insertion of the first ferrule assembly 900a and the second ferrule assembly 900b, respectively. The first ferrule assembly 900a and the second ferrule assembly 900b are vertically stacked. For example, the second ferrule assembly 900b is located below the first ferrule assembly 900a.

[0215] In some embodiments, a support plate 723 is provided between the second interface 721 and the third interface 722. The support plate 723 serves as a spacer between the second interface 721 and the third interface 722, providing stable support for the first ferrule assembly 900a and the second ferrule assembly 900b, and separating the first ferrule assembly 900a and the second ferrule assembly 900b and limiting their relative displacement.

[0216] In some embodiments, a first limiting portion 731 is formed on the top surface 730 to limit its connection with the inner wall of the upper housing 201. A second limiting portion 751 is formed on the bottom surface 750 to limit its connection with the lower housing 202, preventing longitudinal displacement of the fiber optic adapter 700. Exemplarily, the first limiting portion 731 and the second limiting portion 751 are disposed opposite to each other, with the first limiting portion 731 protruding toward the inner wall of the upper housing 201 and the second limiting portion 751 protruding toward the lower housing 202.

[0217] In some embodiments, the top surface 730 has a first latching portion 732 for latching with the inner wall of the upper housing 201 to prevent the fiber optic adapter 700 from moving back and forth due to external force. The bottom surface 750 has a second latching portion 752 for latching with the lower housing 202 to prevent the fiber optic adapter 700 from moving back and forth.

[0218] In some embodiments, the first latching portion 732 is connected to the upper housing 201. The area of ​​the first latching portion 732 is larger than the area of ​​the first limiting portion 731, which increases the contact area between the fiber optic adapter 700 and the upper housing 201 and improves the heat dissipation efficiency between the fiber optic adapter 700 and the upper housing 201, so that the heat generated by the optical module can be effectively conducted to the upper housing 201 through the fiber optic adapter 700, thereby dissipating heat to the outside of the optical module.

[0219] In some embodiments, the first ferrule assembly 900a may include a first ferrule fixing member 920a. The first ferrule fixing member 920a includes a first fixing arm 921a and a second fixing arm 922a disposed opposite to each other, which clamp and fix the first optical fiber ferrule 910a from above and below, thereby reducing loosening or displacement of the first optical fiber ferrule 910a during assembly and use, and improving the stability of the optical fiber connection.

[0220] In some embodiments, the second ferrule assembly 900b may include a second ferrule retainer 920b. The second ferrule retainer 920b includes a third retaining arm 921b and a fourth retaining arm 922b disposed opposite to each other, which clamp and fix the second optical fiber ferrule 910b from above and below.

[0221] In some embodiments, the extending directions of the first fixing arm 921a and the second fixing arm 922a are consistent with the insertion direction of the first ferrule assembly 900a, so as to clamp the first optical fiber ferrule 910a. Similarly, the extending directions of the third fixing arm 921b and the fourth fixing arm 922b are consistent with the insertion direction of the second ferrule assembly 900b, so as to clamp the second optical fiber ferrule 910b.

[0222] In some embodiments, the upper surface of the second interface 721 has a downwardly protruding first boss 781 and a second boss 782, and a first clearance portion 7169a is formed between the first boss 781 and the second boss 782 to avoid the first fixed support arm 921a. At the same time, the first clearance portion 7169a plays a guiding and stopping role for the insertion.

[0223] In some embodiments, the lower surface of the second interface 721 is formed with an upwardly protruding third boss 783 and a fourth boss 784, and a second clearance portion 7169b is formed between the third boss 783 and the fourth boss 784 to avoid the second fixed support arm 922a. At the same time, the second clearance portion 7169b plays a guiding and stopping role for the insertion.

[0224] In some embodiments, the upper surface of the third interface 722 is formed with a downwardly protruding fifth boss 785 and a sixth boss 786, and a third clearance portion 7169c is formed between the fifth boss 785 and the sixth boss 786 to avoid the third fixed support arm 921b. At the same time, the third clearance portion 7169c plays a guiding and stopping role for the insertion.

[0225] In some embodiments, the lower surface of the third interface 722 is formed with an upwardly protruding seventh boss 787 and an eighth boss 788, and a fourth clearance portion 7169d is formed between the seventh boss 787 and the eighth boss 788 to avoid the fourth fixed support arm 922b. At the same time, the fourth clearance portion 7169d plays a guiding and stopping role for the insertion.

The top surface of the first engaging portion 732 is higher than the connecting surface between the first limiting portion 731 and the first engaging portion 732, and the connecting surface between the first limiting portion 731 and the first engaging portion 732 forms an engaging recess with the side wall of the first engaging portion 732, which facilitates engaging.

[0232] In some embodiments, the first limiting portion 731 is located at the middle of the top surface 730, and its two ends are respectively a certain distance from the edge of the fiber optic adapter 700. Exemplarily, the length of the first limiting portion 731 is shorter than the length of the first latching portion 732.

[0254] Figure 19 This is a cross-sectional structural diagram of a fiber optic adapter according to some embodiments. For example... Figure 19 As shown, in some embodiments, a second clearance portion 7169b is formed between the third boss 783 and the fourth boss 784 to avoid the second fixed support arm 922a.

[0255] In some embodiments, the third mating surface 7163 and the fourth mating surface 7164 are respectively provided as inclined surfaces.

[0256] Figure 20 This is an exploded view of an assembly of a fiber optic adapter, a first ferrule assembly, and a second ferrule assembly according to some embodiments. Figure 20 As shown, in some embodiments, one end of the fiber optic adapter 700 has a second interface 721 and a third interface 722, which are arranged one above the other to form a double-layer insertion channel for insertion of the first ferrule assembly 900a and the second ferrule assembly 900b, respectively.

[0261] In some embodiments, taking the second inclined surface 9212 as an example, the second inclined surface 9212 is parallel to the second mating surface 7162, and the fourth inclined surface 9222 is parallel to the fourth mating surface 7164. This parallel inclined surface design helps the first ferrule assembly 900a to be more easily aligned when inserted into the fiber optic adapter 700. Simultaneously, the second mating surface 7162 can serve as a limiting surface; the cooperation between the second inclined surface 9212 and the second mating surface 7162 prevents the first ferrule assembly 900a from over-inserting or re-extracting. When the first ferrule assembly 900a is inserted along the insertion direction, upon contact with the second mating surface 7162, the second mating surface 7162 generates resistance, preventing the first ferrule assembly 900a from continuing to insert, thereby limiting the first ferrule assembly 900a to the target position, forming a motion limiting mechanism. The remaining sets of parallel inclined surfaces in the fiber optic adapter 700 and the first ferrule assembly 900a have the same function. In the fiber optic adapter 700 and the second ferrule assembly 900b, the sets of parallel inclined surfaces have the same function.

[0262] Figure 21 This is a side view of a fiber optic adapter according to some embodiments. Figure 21 As shown, in some embodiments, one end of the fiber optic adapter 700 has a second interface 721 and a third interface 722, which are arranged one above the other to form a double-layer insertion channel for the first ferrule assembly 900a and the second ferrule assembly 900b to be inserted respectively.

[0263] In some embodiments, the upper surface of the fiber optic adapter 700 has a first limiting portion 731 and a first snap-fit ​​portion 732. The surface of the first snap-fit ​​portion 732 protrudes to snap-fit ​​and limit the upper housing 201.

[0264] In some embodiments, the fiber optic adapter 700 has a first receiving groove 7181. The first receiving groove 7181 extends inward. One end of the first receiving groove 7181 is open, and the other end is closed, to receive and fix a structural member inserted along the opening.

[0265] In some embodiments, the fiber optic adapter 700 has a second receiving groove 7182. The second receiving groove 7182 is located below the first receiving groove 7181. The second receiving groove 7182 extends inward, with one end open and the other end closed.

[0266] In some embodiments, the fiber optic adapter 700 has a third receiving groove 7183. The third receiving groove 7183 is located below the second receiving groove 7182, which is located between the first receiving groove 7181 and the third receiving groove 7183. The third receiving groove 7183 extends inward, with one end open and the other end closed.

[0267] In some embodiments, the height of the second receiving groove 7182 is greater than the height of the first receiving groove 7181 or the height of the third receiving groove 7183.

[0268] Figure 22 This is a cross-sectional view of an assembly of an optical fiber adapter, a first clamping limiter, and a second clamping limiter according to some embodiments. Figure 23 An assembly disassembly of an optical fiber adapter, a first clamping limiter, and a second clamping limiter according to some embodiments is provided. Figure 1 .like Figure 22 and Figure 23 As shown, in some embodiments, the fiber optic adapter 700 includes a first receiving slot 7181, a second receiving slot 7182, and a third receiving slot 7183. One end of the first receiving slot 7181 is an open end, and the other end is a closed end, extending from the open end into the fiber optic adapter 700 and stopping at the closed end.

[0269] In some embodiments, the fiber optic adapter 700 may include a first clamping and limiting member 760 for clamping and limiting the first ferrule assembly 900a, ensuring the stability of the first ferrule assembly 900a within the fiber optic adapter 700, preventing the first ferrule fixing member from shaking or falling off within the fiber optic adapter, and improving the reliability and stability of the connection.

[0270] In some embodiments, the fiber optic adapter 700 may include a second clamping and limiting member 770 for clamping and limiting the second ferrule assembly 900b to ensure the stability of the second ferrule assembly 900b within the fiber optic adapter 700.

[0271] In some embodiments, the first clamping limiting member 760 includes a first clamping arm 761 and a second clamping arm 762. The first clamping arm 761 and the second clamping arm 762 are cantilever arms disposed opposite to each other.

[0272] In some embodiments, the second clamping limiting member 770 includes a third clamping arm 771 and a fourth clamping arm 772. The third clamping arm 771 and the fourth clamping arm 772 are cantilever arms arranged opposite to each other.

[0273] In some embodiments, the first clamping limiting member 760 may include a first connecting plate 763 to connect the first clamping arm 761 and the second clamping arm 762. The second clamping limiting member 770 may include a second connecting plate 773 to connect the third clamping arm 771 and the fourth clamping arm 772.

[0274] In some embodiments, a first receiving groove 7181 is used to receive and fix a first clamping arm 761, wherein the first clamping arm 761 is inserted into the first receiving groove 7181. A second receiving groove 7182 is used to receive and fix a second clamping arm 762 and a third clamping arm 771, wherein the second clamping arm 762 and the third clamping arm 771 are inserted into the second receiving groove 7182. A third receiving groove 7183 is used to receive and fix a fourth clamping arm 772, wherein the fourth clamping arm 772 is inserted into the third receiving groove 7183.

[0275] In some embodiments, since the second receiving groove 7182 simultaneously accommodates the second clamping arm 762 and the third clamping arm 771, the height of the second receiving groove 7182 is greater than the height of the first receiving groove 7181 or the height of the third receiving groove 7183, so as to provide a larger receiving space.

[0276] In some embodiments, the first clamping arm 761 and the second clamping arm 762 are respectively inserted into the first receiving groove 7181 and the second receiving groove 7182 provided above and below, so as to clamp and limit the first ferrule assembly 900a.

[0277] In some embodiments, the third clamping arm 771 and the fourth clamping arm 772 are respectively inserted into the upper and lower arranged second receiving grooves 7182 and third receiving grooves 7183 to clamp and limit the second ferrule assembly 720a.

[0278] In some embodiments, the first receiving groove 7181 extends laterally into the cavity formed by the inner wall of the top surface of the second interface 721 and the first boss 781, and passes through the first clearance portion 7169a. The extending direction of the first receiving groove 7181 is the same as the extending direction of the first clamping arm 761. The first receiving groove 7181 provides receiving space for the first clamping arm 761, thereby fixing the first clamping arm 761.

[0279] In some embodiments, the second receiving groove 7182 extends laterally into the cavity formed by the third boss 783 and the fifth boss 785, and the upper surface of the second receiving groove 7182 passes through the second clearance portion 7169b to receive and fix the second clamping arm 762. The lower surface of the second receiving groove 7182 passes through the third clearance portion 7169c to receive and fix the third clamping arm 771. Thus, the second receiving groove 7182 provides receiving space for both the second clamping arm 762 and the third clamping arm 771. Exemplarily, the second clamping arm 762 and the third clamping arm 771 are stacked within the second receiving groove 7182.

[0280] In some embodiments, the third receiving groove 7183 extends laterally into the cavity formed by the inner wall of the bottom surface of the seventh boss 787 and the third interface 722, and passes through the fourth clearance portion 7169d. The third receiving groove 7183 provides receiving space for the fourth clamping arm 772, thereby fixing the fourth clamping arm 772.

[0281] In some embodiments, the first receiving groove 7181 is formed by hollowing out the cavity formed between the inner wall of the top surface of the fiber optic adapter 700 and the plane where the first protrusion 781 is located.

[0282] In some embodiments, the third boss 783 and the fourth boss 784 protrude upwards, and the fifth boss 785 and the sixth boss 786 protrude downwards. This forms a larger first cavity between the third boss 783 and the fifth boss 785, and a larger second cavity between the fourth boss 784 and the sixth boss 786. This is more conducive to forming a second receiving groove 7182 with a larger accommodating space. Exemplarily, the second receiving groove 7182 is formed by hollowing out the first and second cavities, and its upper surface includes a second clearance portion, and its lower surface includes a third clearance portion.

[0283] Figure 24 This is a structural diagram of a first receiving groove according to some embodiments. Figure 24 As shown, in some embodiments, the first receiving groove 7181 is formed by hollowing out the cavity formed between the inner wall of the top surface of the fiber optic adapter 700 and the plane where the first boss 781 is located.

[0284] In some embodiments, the first receiving groove 7181 is formed by the plane containing the first clearance portion 7169a. The first clamping arm 761 passes through the plane containing the first clearance portion 7169a, thereby clamping the first fixing arm 921a. Exemplarily, the extending direction of the first fixing arm 921a is consistent with the insertion direction of the first insert assembly 900a, and the extension direction of the first clamping arm 761 intersects with the extending direction of the first fixing arm 921a. The second receiving groove 7182 and the third receiving groove 7183 operate on the same principle.

[0285] Figure 25 This is an assembly drawing of an optical fiber adapter, a first clamping limiter, and a second clamping limiter according to some embodiments. Figure 26a An assembly disassembly of an optical fiber adapter, a first clamping limiter, and a second clamping limiter according to some embodiments is provided. Figure 2 , Figure 26b This is a cross-sectional view of an assembly of a fiber optic adapter, a first clamping limiter, and a second clamping limiter according to some embodiments. Figures 25-26bAs shown, in some embodiments, the first clamping arm 761 is inserted into the first receiving groove 7181, the second clamping arm 762 and the third clamping arm 771 are inserted into the second receiving groove 7182, and the fourth clamping arm 772 is inserted into the third receiving groove 7183.

[0286] In some embodiments, the first connecting plate 763 and the second connecting plate 773 are respectively fixed to the surface of the fiber optic adapter 700. The first connecting plate 763 connects the first clamping arm 761 and the second clamping arm 762, with the first clamping arm 761 located at one end of the first connecting plate 763 and the second clamping arm 762 located at the other end of the first connecting plate 763. The second connecting plate 773 connects the third clamping arm 771 and the fourth clamping arm 772, with the third clamping arm 771 located at one end of the second connecting plate 773 and the fourth clamping arm 772 located at the other end of the second connecting plate 773.

[0287] like Figure 26a As shown, in some embodiments, the first clamping limiter 760 may include a first fitting portion 764. The first fitting portion 764 is formed at an end and is connected to the first connecting plate 763.

[0288] In some embodiments, the second clamping limiter 770 may include a second fitting portion 774. The second fitting portion 774 is formed at an end and is connected to the second connecting plate 773.

[0289] In some embodiments, the first fitting portion 764 includes a first positioning branch 7641 and a first connecting branch 7642. The first positioning branch 7641 and the first connecting branch 7642 are perpendicularly connected to each other. The size of the first positioning branch 7641 is larger than the size of the first connecting branch 7642. Exemplarily, the two form a T-shape.

[0290] In some embodiments, the second fitting portion 774 includes a second positioning branch 7741 and a second connecting branch 7742. The second positioning branch 7741 and the second connecting branch 7742 are perpendicularly connected to each other. The second positioning branch 7741 is larger than the second connecting branch 7742. Exemplarily, they form a T-shape.

[0291] In some embodiments, a first interlocking groove 7171 is formed on the surface of the fiber optic adapter 700. Exemplarily, the first interlocking groove 7171 is formed on the surface of the side 740. A first fitting portion 764 is fitted into the first interlocking groove 7171, thereby fixing the first clamping limiting member 760 to the surface of the fiber optic adapter 700.

[0292] In some embodiments, a second interlocking groove 7172 is formed on the surface of the fiber optic adapter 700. Exemplarily, the second interlocking groove 7172 is formed on the surface of the side 740. The second interlocking groove 7172 is located on one side of the first interlocking groove 7171. A second fitting portion 774 is fitted into the second interlocking groove 7172, thereby fixing the second clamping limiting member 770 to the surface of the fiber optic adapter 700.

[0293] In some embodiments, a spacer 7173 is formed between the first interlocking groove 7171 and the second interlocking groove 7172. The spacer 7173 is interlocked with the first interlocking groove 7171 and the second interlocking groove 7172 in an alternating manner. For example, the first interlocking groove 7171 and the second interlocking groove 7172 are T-shaped slots, and the spacer 7173 is an inverted T-shape, with the spacer 7173 interlocking with the first interlocking groove 7171 and the second interlocking groove 7172 in an alternating manner. Correspondingly, the first interlocking portion 764 and the second interlocking portion 774 are T-shaped structural portions.

[0294] like Figure 26b As shown, in some embodiments, the first clamping and limiting member 760 may include a first insert piece 765. The first insert piece 765 is located below the first mating portion 764. The second clamping and limiting member 770 may include a second insert piece. The second insert piece is located below the second mating portion 774. The position and structure of the second insert piece can be referenced to the first insert piece 765.

[0295] In some embodiments, a first insertion hole 7174 is provided below the first insertion groove 7171, and a second insertion hole 7175 is provided below the second insertion groove 7172.

[0296] In some embodiments, the first plug tab 765 and the second plug tab can be elastic plug tabs, capable of undergoing a certain degree of elastic deformation. When the first clamping and limiting member 760 is assembled to the side 740, the end face of the first plug tab 765 undergoes elastic deformation upon contacting the edge of the first plug hole 7174, adapting to the first plug hole 7174 and smoothly entering it. When the first plug tab 765 is fully inserted into the first plug hole 7174, its elastic deformation returns to its original shape, creating mechanical interference with the first plug hole 7174. Through the insertion and engagement of the first plug tab 765 and the first plug hole 7174, the first clamping and limiting member 760 is fixed to the fiber optic adapter 700.

[0297] In some embodiments, the engagement of the first interlocking slot 7171 and the first mating portion 764 effectively restricts the movement of the first clamping limiting member 760 along the length direction of the side of the fiber optic adapter 700, while the engagement of the first insertion hole 7174 and the first insertion piece 765 effectively restricts the movement of the first clamping limiting member 760 along the width direction of the side of the fiber optic adapter 700. This multi-directional limiting design ensures the positional accuracy and stability of the first clamping limiting member 760 on the fiber optic adapter 700, preventing it from loosening or shifting during use.

[0298] Figure 27 For assembling a first clamping limiting member with a first ferrule assembly according to some embodiments Figure 1 , Figure 28 For assembling a first clamping limiting member with a first ferrule assembly according to some embodiments Figure 2 .like Figure 27 and Figure 28 As shown, in some embodiments, the first fiber optic ferrule 910a is fixed between the first fixed arm 921a and the second fixed arm 922a. In the first clamping and limiting member 760, the first clamping arm 761 and the second clamping arm 762 respectively clamp the first fixed arm 921a and the second fixed arm 922a, thereby clamping and limiting the first ferrule assembly 900a.

[0299] In some embodiments, the first clamping arm 761 is arranged crosswise with the first fixing arm 921a to apply a clamping force. The second clamping arm 762 is arranged crosswise with the second fixing arm 922a to apply a clamping force.

[0300] In some embodiments, a first stop surface 9215 is formed at the end of the first fixed support arm 921a, and the first stop surface 9215 is configured as an inclined surface. When the first ferrule assembly 900a is inserted, when the first stop surface 9215 contacts the first clamping support arm 761, the inclined surface gradually increases the contact area, generating resistance and preventing the first ferrule assembly 900a from being further inserted.

[0301] In some embodiments, a first protrusion 9216 is formed on the surface of the first fixed arm 921a. The first clamping arm is located between the first protrusion 9216 and the first stop surface 9215. The space between the first protrusion 9216 and the first stop surface 9215 indicates a precise assembly position for the first clamping arm 761, ensuring the assembly accuracy of the first clamping arm 761 and preventing it from shaking or shifting during use. At the same time, the first protrusion 9216 and the first stop surface 9215 can constrain the first clamping arm 761 from both sides, preventing the first clamping arm 761 from falling off.

[0302] In some embodiments, the optical port formed by the upper housing 201 and the lower housing 202 is not equipped with a fiber optic adapter 700. Instead, the fiber optic adapter 700 is absorbed by the inner walls of the upper housing 201 and the lower housing 202, respectively. Consequently, the first fiber optic connector 800a and the second fiber optic connector 800b are directly assembled between the upper housing 201 and the lower housing 202, and the first ferrule assembly 900a and the second ferrule assembly 900b are also directly assembled between the upper housing 201 and the lower housing 202. Details are not elaborated on when the structures are identical. For any omissions or deficiencies in the following embodiments, please refer to the aforementioned embodiments where the optical port formed by the upper housing 201 and the lower housing 202 is equipped with a fiber optic adapter 700.

[0303] Figure 29 This is a schematic diagram of the inner wall structure of an upper housing according to some embodiments. For example... Figure 29 As shown, in some embodiments, a first mounting groove 2015 is formed on the inner wall of the end of the upper housing 201 for the first fiber optic connector 800a to be connected to the inner wall of the upper housing 201.

[0304] In some embodiments, the first assembly groove 2015 is adapted to the end of the first fiber optic connector 800a, so that the outer wall of the first fiber optic connector 800a is embedded in the first assembly groove 2015.

[0305] In some embodiments, a first limiting boss 2016a and a second limiting boss 2016b are formed on the inner wall of the upper housing 201. The first limiting boss 2016a and the second limiting boss 2016b are located on one side of the first assembly groove 2015. The functions of the first limiting boss 2016a and the second limiting boss 2016b are the same as those of the first boss 781 and the second boss 782, respectively. A first clearance portion 2016c is formed between the first limiting boss 2016a and the second limiting boss 2016b, which is also for clearance and embedding of the first fixed support arm 921a. At the same time, the first clearance portion 2016c plays a guiding and stopping role for the insertion.

[0306] In some embodiments, similarly, the first limiting boss 2016a includes a first mating surface 20161, and the second limiting boss 2016b includes a second mating surface 20162. When the first ferrule assembly 900a is assembled with the upper housing 201, the first mating surface 20161 and the second mating surface 20162 can provide resistance to the upper surface of the first ferrule assembly 900a, preventing the first ferrule assembly 900a from being over-inserted, thereby inserting the first ferrule assembly 900a into the target position.

[0307] Figure 30 This is a schematic diagram of the inner wall structure of a lower housing according to some embodiments. Figure 30As shown, in some embodiments, a second mounting groove 2026 is formed on the inner wall of the lower housing 202 to allow the second fiber optic connector 800b to be connected to the inner wall of the lower housing 202.

[0308] In some embodiments, the second assembly groove 2026 is adapted to the end of the second fiber optic connector 800b, such that the outer wall of the second fiber optic connector 800b is embedded in the second assembly groove 2026.

[0309] In some embodiments, a third limiting boss 2027a and a fourth limiting boss 2027b are formed on the inner wall of the lower housing 202. The third limiting boss 2027a and the fourth limiting boss 2027b are located on one side of the second mounting groove 2026. A second clearance portion 2027c is formed between the third limiting boss 2027a and the fourth limiting boss 2027b to clearance and embed the fourth fixed support arm.

[0310] In some embodiments, the third limiting boss 2027a includes a third mating surface 20271, and the fourth limiting boss 2027b includes a fourth mating surface 20272. When the second ferrule assembly 900b is assembled with the lower housing 202, the third mating surface 20271 and the fourth mating surface 20272 can provide resistance to the lower surface of the second ferrule assembly 900b, preventing the second ferrule assembly 900b from being over-inserted, thereby inserting the second ferrule assembly 900b into the target position.

[0311] Figure 31 This is a structural diagram of an upper housing and lower housing side plates according to some embodiments. For example... Figure 31 As shown, in some embodiments, the ends of the first fiber optic connector 800a and the second fiber optic connector 800b can be inserted into the cavity formed by the upper housing 201 and the lower housing 202.

[0312] In some embodiments, a first latch 801a is formed on the side of the first fiber optic connector 800a, and a second latch 801b is formed on the side of the second fiber optic connector 800b. Exemplarily, the first latch 801a and the second latch 801b can be resilient latches.

[0313] In some embodiments, the upper housing 201 may include an upper side plate 2017. The upper side plate 2017 is connected to the cover plate 2011 and extends into the lower housing 202.

[0314] In some embodiments, the lower housing 202 may include a lower side plate 2022. The lower side plate 2022 is closed and connected to the upper side plate 2017 to form a cavity, into which a first fiber optic connector 800a and a second fiber optic connector 800b are inserted. A first assembly groove 2015 and a second assembly groove 2026 form the cavity.

[0315] In some embodiments, the upper side plate 2017 has a first mounting hole 20171, which can be a through hole. The first mounting hole 20171 is engaged with the first snap-fit ​​801a.

[0316] In some embodiments, the lower side plate 2022 has a second mounting hole 20221, which can be a through hole. The second mounting hole 20221 is engaged with the second snap-fit ​​801b.

[0317] In some embodiments, when assembling the first fiber optic connector 800a, the first latch 801a, under the action of elastic deformation, is fitted into the first mounting hole 20171, fixing the first fiber optic connector 800a to the surface of the upper side plate 2017 to prevent loosening or falling off. Similarly, when assembling the second fiber optic connector 800b, the second latch 801b, under the action of elastic deformation, is fitted into the second mounting hole 20221, fixing the second fiber optic connector 800b to the lower side plate 2022 to prevent loosening or falling off. By pressing the first latch 801a and the second latch 801b, the first fiber optic connector 800a and the second fiber optic connector 800b can be removed respectively.

[0318] In some embodiments, the first clamping limiting member includes a first fitting portion, a first connecting plate, a first clamping arm, and a second clamping arm. The first fitting portion fits into the surface of the upper side plate, limiting the first clamping limiting member to the upper side plate. The first connecting plate extends along the surface of the upper side plate to connect the first clamping arm and the second clamping arm, so that the first clamping arm and the second clamping arm extend into the optical module, thereby clamping the upper and lower surfaces of the first ferrule fixing member, respectively. The first clamping arm extends into the interior of the upper housing to clamp and fix the upper surface of the first ferrule fixing member. The second clamping arm extends into the cavity formed by the upper housing and the lower housing to clamp and fix the lower surface of the first ferrule fixing member. Correspondingly, the second clamping limiting member is used to clamp and fix the second ferrule fixing member. The second clamping limiting member includes a second fitting portion, a second connecting plate, a third clamping arm, and a fourth clamping arm. The second fitting portion is fixed to the side of the lower side plate, and the second connecting plate extends along the surface of the lower side plate. The third clamping arm extends into the cavity formed by the upper and lower housings to clamp and fix the upper surface of the second insert fixing member. The fourth clamping arm extends into the lower housing to clamp and fix the lower surface of the second insert fixing member.

[0319] In some embodiments, the upper side plate 2017 has a first fitting groove 20172. The first fitting groove 20172 is located on one side of the first mounting hole 20171. Similarly, the first fitting portion 764 is fitted into the first fitting groove 20172, thereby fixing the first clamping limiter 760 to the side of the upper housing 201.

[0320] In some embodiments, the lower side plate 2022 is formed with a second fitting groove 20222. The second fitting groove 20222 is located on one side of the second mounting hole 20221. Similarly, the second fitting portion 774 is fitted into the second fitting groove 20222, thereby fixing the second clamping limiter 770 to the side of the lower housing 202.

[0321] Figure 32 This is a diagram illustrating an assembly structure of an upper and lower housing according to some embodiments. Figure 32 As shown, in some embodiments, the upper housing 201 and the lower housing 202 are closed and connected.

[0322] In some embodiments, a first receiving groove 2018 is formed in the inner cavity of the upper housing 201. The first receiving groove 2018 extends into the upper housing 201 along the upper side plate 2017. One end of the first receiving groove 2018 is open and the other end is closed to accommodate and fix the first clamping arm 761 inserted along the first receiving groove 2018.

[0323] In some embodiments, a second receiving groove 2028 is formed in the inner cavity of the lower housing 202, and the second receiving groove 2028 extends into the lower housing 202 along the lower side plate 2022. One end of the second receiving groove 2028 is open and the other end is closed to accommodate and fix the fourth clamping arm 772 inserted along the second receiving groove 2028.

[0324] In some embodiments, a third receiving groove 2035 is formed in the middle of the cavity formed by the upper housing 201 and the lower housing 202. The third receiving groove 2035 is located between the first receiving groove 2018 and the second receiving groove 2028. One end of the third receiving groove 2035 is open and the other end is closed to accommodate and fix the second clamping arm 762 and the third clamping arm 771 inserted along the third receiving groove 2035.

[0325] In some embodiments, a fifth limiting boss 2031 and a sixth limiting boss 2032 are formed on the upper wall of the third receiving groove 2035. The structures of the fifth limiting boss 2031 and the sixth limiting boss 2032 are respectively symmetrically arranged with respect to the first limiting boss 2016a and the second limiting boss 2016b. When the first insert assembly 900a is assembled and connected to the upper housing 201, the fifth limiting boss 2031 and the sixth limiting boss 2032 can provide resistance to the lower surface of the first insert assembly 900a, preventing the first insert assembly 900a from being over-inserted, thereby inserting the first insert assembly 900a into the target position. Similarly, a clearance portion is formed between the fifth limiting boss 2031 and the sixth limiting boss 2032 to avoid and embed the second fixed support arm.

[0326] In some embodiments, a seventh limiting boss 2033 and an eighth limiting boss 2034 are formed on the lower wall of the third receiving groove 2035.
