[0106] 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.

[0107] 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.

[0108] 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.

[0109] 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.

[0110] 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.

[0111] 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.

[0112] 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.

[0113] 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.

[0114] 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.

[0115] In addition to optical network terminals, the host computer 100 also includes optical line terminals (OLTs), optical network equipment (ONTs), or data center servers.

[0116] 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.

[0117] 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.

[0118] 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 3 and Figure 4 As shown, the optical module 200 includes a shell, a circuit board 300 disposed within the shell, a light emitting component 400, and a light receiving component 500. However, this disclosure is not limited thereto; in some embodiments, the optical module 200 includes one of the light emitting component 400 and the light receiving component 500.

[0119] The housing includes an upper housing 201 and a lower housing 202, with the upper housing 201 covering the lower housing 202 to form the aforementioned housing having two openings 204 and 205; the outer contour of the housing is generally square.

[0120] 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.

[0121] 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.

[0122] 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 (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. Opening 204 is an electrical port, through which the gold fingers 301 of circuit board 300 extend and are inserted into the electrical connector of host computer 100; opening 205 is an optical port, configured to connect to external optical fiber 101 so that optical fiber 101 connects optical emitting component 400 and optical receiving component 500 in optical module 200.

[0123] The assembly method using an upper housing 201 and a lower housing 202 facilitates the installation of the circuit board 300, the light emitting component 400, the light receiving component 500, etc., into the aforementioned housings. The upper housing 201 and the lower housing 202 can encapsulate and protect these devices. Furthermore, the assembly of the circuit board 300, the light emitting component 400, and the light receiving component 500 facilitates the deployment of positioning components, heat dissipation components, and electromagnetic shielding components for these devices, which is beneficial for automated production.

[0124] In some embodiments, the upper housing 201 and the lower housing 202 are made of metal materials, which facilitates electromagnetic shielding and heat dissipation.

[0125] 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.

[0126] 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.

[0127] Circuit board 300 includes circuit traces, electronic components, and chips. The circuit traces connect the electronic components and chips according to the circuit design to achieve 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, for example, microcontroller units (MCUs), laser driver chips, transimpedance amplifiers (TIAs), limiting amplifiers, clock and data recovery (CDR) chips, power management chips, and digital signal processing (DSP) chips.

[0128] Circuit board 300 is generally a rigid circuit board. Due to its relatively hard material, the rigid circuit board can also perform a load-bearing function. For example, the rigid circuit board can stably support the aforementioned electronic components and chips. The rigid circuit board can also be inserted into the electrical connector in the cage 106 of the host computer 100.

[0129] The circuit board 300 also includes gold fingers 301 formed on its end surface, the gold fingers 301 consisting of a plurality of independent pins. The circuit board 300 is inserted into the cage 106 and is connected to an electrical connector within the cage 106 by the gold fingers 301. The gold fingers 301 may be provided only on one side of the surface of the circuit board 300 (e.g., Figure 4The upper surface shown can also be positioned on the upper and lower surfaces of the circuit board 300 to provide a greater number of pins, thus adapting to applications with high pin count requirements. The gold fingers 301 are configured to establish an electrical connection with the host computer to achieve power supply, grounding, two-wire synchronous serial (Inter-Integrated Circuit, I2C) signal transmission, and data signal transmission. Of course, flexible circuit boards are also used in some optical modules. Flexible circuit boards are generally used in conjunction with rigid circuit boards as a supplement to rigid circuit boards.

[0130] At least one of the light emitting component 400 or the light receiving component 500 is located on the side of the circuit board 300 away from the gold finger 301.

[0131] In some embodiments, the light emitting component 400 and the light receiving component 500 are physically separated from the circuit board 300, and then electrically connected to the circuit board 300 through corresponding flexible circuit boards or electrical connectors.

[0132] In some embodiments, at least one of the light emitting component or the light receiving component may be directly disposed on the circuit board 300. For example, at least one of the light emitting component or the light receiving component may be disposed on the surface of the circuit board 300 or the side of the circuit board 300.

[0133] In some embodiments, the optical module may include an optical fiber ribbon 400a. The optical fiber ribbon 400a may be disposed on the surface of the circuit board 300. The optical fiber ribbon 400a may transmit optical signals emitted by the optical emitting component 400 to the outside, and may also transmit external optical signals to the optical receiving component 500.

[0134] In some embodiments, the optical module 200 may include a fastener 700. The fastener 700 can secure the optical fiber ribbon 400a, providing a support structure for the optical fiber ribbon 400a and preventing it from breaking under external forces. The optical fiber ribbon 400a can pass through the fastener 700 and extend to the outside of the optical module.

[0135] In some embodiments, the fiber ribbon 400a extends outward from the optical module to form a pigtail 800. The pigtail 800 may include a storage cavity in which the fiber ribbon 400a can be placed.

[0136] In some embodiments, the fiber optic ribbon 400a can be bound to a fixing rod. One end of the fixing rod can extend into the fixing through hole of the fixing member 700, and the other end of the fixing rod can extend into the snap-fit ​​of the snap-fit ​​member of the circuit board 300, so that the fiber optic ribbon 400a between the fixing member 700 and the snap-fit ​​member is less affected by tensile stress and shear stress, thereby protecting the fiber optic ribbon 400a.

[0137] In some embodiments, the bonding connection between the fiber optic ribbon 400a and the fixing rod can be achieved by means of heat shrink tubing or adhesive tape. Heat shrink tubing or adhesive tape can tightly wrap the fiber optic ribbon 400a and the fixing rod, preventing the fiber optic ribbon 400a from sliding or falling off the fixing rod.

[0138] In some embodiments, the optical fiber ribbon 400a can be bound to a fixing rod. One end of the fixing rod can extend into the fixing through hole of the fixing member 700 and connect to the fixing member 700, while the other end of the fixing rod is suspended. The optical fiber protection member 900 can be snapped onto the circuit board 300. The insertion of one end of the fixing rod into the fixing member 700 and the suspension of the other end, along with the snapping of the optical fiber protection member 900 onto the circuit board 300, minimizes the impact of tensile stress on the optical fiber ribbon 400a, thus protecting it.

[0139] In some embodiments, the optical module 200 further includes an optical fiber protection component 900. The optical fiber protection component 900 can be snapped onto the inner wall of the lower housing 202 to connect the optical fiber protection component 900 to the lower housing 202. One end of the optical fiber protection component 900 can be snapped onto the circuit board 300. The other end of the optical fiber protection component 900 can be snapped onto the fixing component 700 and the pigtail 800. With one end of the optical fiber protection component 900 snapped onto the circuit board 300 and the other end snapped onto the pigtail 800, the pigtail 800, the optical fiber protection component 900, and the circuit board 300 form an assembly unit. During assembly, not only can the optical fiber ribbon 400a of this assembly unit be coupled to the optical transmitting component 400 and the optical receiving component 500, but the assembly unit can also be simultaneously assembled inside the housing to reduce stress damage to the optical fiber ribbon 400a caused by tension, shearing, and torsion, thus protecting the optical fiber ribbon 400a.

[0140] Figure 5 This is a diagram of the internal structure of an optical module according to some embodiments, viewed from another perspective. Figure 4 and Figure 5 As shown, in some embodiments, the optical emitting component 400 can be embedded in the circuit board 300. The optical emitting component 400 can be connected to an optical fiber ribbon 400a so that the optical fiber ribbon 400a can transmit the optical signal emitted by the optical emitting component 400 outward.

[0141] In some embodiments, the optical receiving component 500 may be disposed on the lower surface of the circuit board 300. The optical receiving component 500 may be offset from the optical emitting component 400 along the width direction of the circuit board 300. The optical receiving component 500 may be connected to an optical fiber ribbon 400a so that the optical fiber ribbon 400a can transmit external optical signals to the optical receiving component 500.

[0142] Figure 6a This is an exploded view of the internal structure of an optical module according to some embodiments. Figure 6bA partial view of the internal structure of an optical module according to some embodiments. Figure 1 .like Figure 6a and Figure 6b As shown, in some embodiments, the fixing member 700 may form a fixing through hole 740. The fixing through hole 740 may extend through both ends of the fixing member 700 so that the optical fiber ribbon 400a can pass through the fixing member 700 and enter the storage cavity of the pigtail 800. The optical fiber ribbon 400a is connected to the inner wall of the fixing through hole 740 by adhesive.

[0143] In some embodiments, the fastener 700 may include a first snap-fit ​​portion 710.

[0144] In some embodiments, the fastener 700 may include a second snap-fit ​​portion 720. One end of the second snap-fit ​​portion 720 may be connected to one end of the first snap-fit ​​portion 710.

[0145] In some embodiments, the height of the second latching portion 720 is greater than the height of the first latching portion 710, so that the second latching portion 720 can stop at the limiting protrusion of the optical fiber protection member 900 and define the position of the fixing member 700 from the length direction of the fixing member 700.

[0146] In some embodiments, the fastener 700 may include a third latching portion 730. One end of the third latching portion 730 may be connected to the other end of the second latching portion 720, and the other end of the third latching portion 730 may be connected to the pigtail 800. For example, the other end of the third latching portion 730 is latched into the storage cavity of the pigtail 800 so that the fiber optic ribbon 400a can enter the storage cavity of the pigtail 800.

[0147] In some embodiments, the first latching portion 710 may include a first sub-latching portion 711 and a second sub-latching portion 712. One end of the first sub-latching portion 711 may be connected to one end of the second sub-latching portion 712, and the other end of the second sub-latching portion 712 may be connected to one end of the second latching portion 720.

[0148] In some embodiments, the width of the first sub-connector 711 is greater than the width of the second sub-connector 712.

[0149] The first sub-connector 711 may include a first end face 7111 and a second end face 7113. The first end face 7111 may face the light emitting component 400, and the second end face 7113 may be disposed opposite to the first end face 7111. The second end face 7113 may be connected to one end of the second sub-connector 712.

[0150] The first sub-connector 711 may include a first side surface 7112, one end of which may be connected to the first end surface 7111, and the other end of which may be connected to the second end surface 7113.

[0151] The second sub-connector 712 may include a third end face and a fourth end face, which may be arranged opposite to each other. The third end face may be connected to the second end face of the first sub-connector 711, and the fourth end face may be connected to one end of the second connector 720.

[0152] The second sub-connector 712 may include a second side surface 7121, one end of which may be connected to a third end surface, and the other end of which may be connected to a fourth end surface.

[0153] In some embodiments, the first side 7112 protrudes from the second side 7121, such that the distance between the two oppositely arranged first side 7112 is greater than the distance between the two oppositely arranged second side 7121, that is, the width of the first sub-snap connector 711 is greater than the width of the second sub-snap connector 712.

[0154] The top surface of the first sub-connector 711 and the top surface of the second sub-connector 712 together form a first top surface 713, that is, the top surface of the first connector 710 is the first top surface 713. The first top surface 713 can be limited and connected with the first limiting member of the optical fiber protection component 900, so that the first top surface 713 can stop at the first limiting member, defining the position of the fixing member 700 in the height direction of the optical fiber protection component 900. Defining the position of the fixing member 700 in the height direction of the optical fiber protection component 900 means defining the position of the optical fiber ribbon 400a in the height direction of the optical fiber protection component 900, reducing the possibility of the optical fiber ribbon 400a detaching from the optical fiber protection component 900, reducing the risk of the optical fiber ribbon 400a breaking due to shear stress, and thus protecting the optical fiber ribbon 400a.

[0155] In some embodiments, the second latching portion 720 may include a fifth end face, a sixth end face, and a third side face 721. The fifth end face may be connected to the second sub-latching portion 712, one end of the third side face 721 may be connected to the fifth end face, the other end of the third side face 721 may be connected to the sixth end face, and the sixth end face may be connected to the third latching portion 730.

[0156] In some embodiments, the third side 721 protrudes from the second side 7121, such that the distance between the two oppositely disposed third side 721 is greater than the distance between the two oppositely disposed second side 7121, that is, the width of the second snap-fit ​​portion 720 is greater than the width of the second sub-snap-fit ​​portion 712.

[0157] The top surface of the second snap-fit ​​portion 720 is the second top surface 722, which protrudes from the first top surface 713, so that the second snap-fit ​​portion 720 can stop at the first limiting member of the optical fiber protection member 900 to limit the position of the fixing member 700 from the length direction of the fixing member 700.

[0158] In some embodiments, the bottom surface of the second latching portion 720 protrudes beyond the bottom surface of the first latching portion 710.

[0159] In some embodiments, the bottom surface of the second snap-fit ​​portion 720 protrudes beyond the bottom surface of the third snap-fit ​​portion 730 and the bottom surface of the pigtail 800.

[0160] like Figure 6a and Figure 6b As shown, in some embodiments, a first notch 310 may be formed in the sidewall of the circuit board 300. The first notch 310 may be formed by an inward recess in the sidewall of the circuit board 300. The second limiting member of the fiber optic protector 900 may be engaged at the first notch 310 to define the position of the circuit board 300 along the length direction of the fiber optic protector 900.

[0161] Figure 7a The structure of an optical fiber protection device provided according to some embodiments Figure 1 . Figure 7b The structure of an optical fiber protection device provided according to some embodiments Figure 2 . Figure 7c The structure of an optical fiber protection device provided according to some embodiments Figure 3 .like Figure 7a , Figure 7b and Figure 7c As shown, in some embodiments, the fiber optic protector 900 may include a first fiber optic protective housing 910. The first fiber optic protective housing 910 may be used to attach the pigtail 800 and the fastener 700. For example, the fiber optic protector 900 may be a fiber optic protector 900a, which may include the first fiber optic protective housing 910a.

[0162] In some embodiments, the fiber optic protection element 900 may include a second fiber optic protection housing 930. One end of the second fiber optic protection housing 930 may be connected to the first fiber optic protection housing 910. The other end of the second fiber optic protection housing 930 may be snapped onto the circuit board 300. For example, the fiber optic protection element 900a may include a second fiber optic protection housing 930a, one end of which may be connected to the first fiber optic protection housing 910a.

[0163] The first fiber optic protective housing 910 can be snapped into the pigtail 800 and the fixing component 700, and the second fiber optic protective housing 930 can be snapped into the circuit board 300, so that the fiber optic protective component 900, the pigtail 800, the fixing component 700 and the circuit board 300 form an assembly. During the assembly process, not only can the fiber optic ribbon 400a of the assembly be coupled with the optical transmitting component 400 and the optical receiving component 500, but the assembly can also be installed into the housing at the same time to reduce the stress damage to the fiber optic ribbon 400a caused by tension, shearing, torsion and other stresses, and protect the fiber optic ribbon 400a.

[0164] In some embodiments, the fiber optic protective element 900a may include a third fiber optic protective housing 920. One end of the third fiber optic protective housing 920 may be connected to the first fiber optic protective housing 910, and the other end of the third fiber optic protective housing 920 may be connected to one end of the second fiber optic protective housing 930. The third fiber optic protective housing 920 may house the fiber optic ribbon 400a, effectively managing and protecting the fiber optic ribbon.

[0165] In some embodiments, the width of the third fiber optic protective housing 920 is smaller than that of the first fiber optic protective housing 910 and the second fiber optic protective housing 930. This not only reduces the space occupied by the fiber optic protective component 900 in the width direction, but also confines the fiber optic ribbon 400a within the third fiber optic protective housing 920, preventing the fiber optic ribbon 400a from swaying or shifting over a wide range in the width direction of the fiber optic protective component 900.

[0166] In some embodiments, the fiber optic protector 900 may include a second limiting member 940. The second limiting member 940 may be connected to the first fiber optic protective housing 910. The second limiting member 940 may be limitedly connected to the first top surface 713 of the fixing member 700. For example, the fiber optic protector 900a may include a second limiting member 940a, which may be connected to the first fiber optic protective housing 910a, and the second limiting member 940a may be limitedly connected to the first top surface 713 of the fixing member 700.

[0167] In some embodiments, the fiber optic protective element 900 may include a first limiting element 950. The first limiting element 950 may be connected to the second fiber optic protective housing 930. The first limiting element 950 may be snapped into the notch 310 of the circuit board 300 to limit the connection between the first limiting element 950 and the circuit board 300. For example, the fiber optic protective element 900 may include a first limiting element 950a, which may be connected to the second fiber optic protective housing 930a and may be snapped into the notch 310 of the circuit board 300.

[0168] like Figure 7a , Figure 7b and Figure 7cIn some embodiments, the first fiber optic protective housing 910 may include a first base plate portion 911 and two opposing first side plate portions 912. The bottom of one first side plate portion 912 is connected to one side of the first base plate portion 911, and the bottom of the other first side plate portion 912 is connected to the other side of the first base plate portion 911, so that the first fiber optic protective housing 910 is a U-shaped groove. For example, the first fiber optic protective housing 910 may be a first fiber optic protective housing 910a, and the first side plate portion 912 may be a first side plate portion 912a. The first fiber optic protective housing 910a may include the first base plate portion 911 and the first side plate portion 912a, and the first side plate portion 912a is connected to the first base plate portion 911.

[0169] In some embodiments, the first base plate portion 911 may include a first inner bottom surface 9111. The first inner bottom surface 9111 may be in contact with the bottom of the pigtail 800 so that the first inner bottom surface 9111 can support the pigtail 800.

[0170] In some embodiments, the first base plate portion 911 may include a second inner bottom surface 9112. The second inner bottom surface 9112 may be disposed corresponding to the bottom surface of the second snap-fit ​​portion 720 of the fastener 700. The second inner bottom surface 9112 may be in contact with the bottom surface of the second snap-fit ​​portion 720 so that the second inner bottom surface 9112 can support the second snap-fit ​​portion 720.

[0171] The bottom surface of the second latching portion 720 protrudes beyond the bottom surface of the third latching portion 730 and the bottom surface of the pigtail 800. In some embodiments, the first inner bottom surface 9111 may protrude beyond the second inner bottom surface 9112, allowing both the pigtail 800 and the fixing member 700 to contact and connect with the first base plate portion 911. This increases the contact area between the pigtail 800 and the fixing member 700 and the first base plate portion 911, improving the stability of the connection. This design helps ensure that the pigtail 800 and the fixing member 700 are fixed in position within the optical module, preventing loosening or detachment during use.

[0172] In some embodiments, the first base plate portion 911 may include a third inner bottom surface 9113. The third inner bottom surface 9113 may be disposed corresponding to the bottom surface of the first snap-fit ​​portion 710 of the fastener 700. The third inner bottom surface 9113 may be in contact with the bottom surface of the first snap-fit ​​portion 710 of the fastener 700 so that the third inner bottom surface 9113 can support the first snap-fit ​​portion 710.

[0173] The bottom surface of the second snap-fit ​​portion 720 protrudes from the bottom surface of the first snap-fit ​​portion 710. In some embodiments, the third inner bottom surface 9113 may protrude from the second inner bottom surface 9112, so that the fastener 700 can contact and connect with the first base plate portion 911, thereby increasing the contact area between the fastener 700 and the first base plate portion 911 and improving the stability of the connection.

[0174] In some embodiments, the first base plate portion 911 may include a fourth inner bottom surface 9114. The fourth inner bottom surface 9114 may be disposed corresponding to the bottom surface of the first snap-fit ​​portion 710 of the fastener 700. The fourth inner bottom surface 9114 may be in contact with the bottom surface of the first snap-fit ​​portion 710. One end of the fourth inner bottom surface 9114 may be connected to a second inner bottom surface 9112, and the other end may be connected to the fourth inner bottom surface 9114. For example, the fourth inner bottom surface 9114 is a curved surface to reduce wear on the first snap-fit ​​portion 710.

[0175] In some embodiments, a first limiting surface 9123 may be formed on the inner wall of the first side plate portion 912. The first limiting surface 9123 may be correspondingly disposed with the first end face 7111 of the first sub-clamping portion 711. The first limiting surface 9123 may contact and connect with the first end face 7111 of the first sub-clamping portion 711 to define the position of the first sub-clamping portion 711 in the width direction of the optical fiber protection member 900, so that the fixing member 700 stops in front of the first limiting surface 9123, thereby preventing the fixing member 700 from going too deep into the first optical fiber protection housing 910 and ensuring a stable and reliable connection between the pigtail 800 and the fixing member 700.

[0176] In some embodiments, a second limiting surface 9130 may be formed on the inner wall of the first side plate portion 912. The second limiting surface 9130 may be disposed opposite to the first limiting surface 9123. The second limiting surface 9130 may be disposed corresponding to the second end face 7113 of the fixing member 700. The second limiting surface 9130 may be in contact with the second end face 7113 of the fixing member 700 to further define the position of the first sub-clamping portion 711 in the length direction of the fiber optic protection member 900.

[0177] The first limiting surface 9123 can contact and connect with the first end face 7111 of the fixing member 700, and the second limiting surface 9130 can contact and connect with the second end face 7113 of the fixing member 700. The first end face 7111 and the second end face 7113 of the fixing member 700 are arranged opposite to each other. The position of the first sub-clamping part 711 can be determined from the length direction of the optical fiber protection member 900, and then the position of the fixing member 700 can be determined from the length direction of the optical fiber protection member 900a. This effectively restricts the movement of the fixing member 700 in the length direction of the optical fiber protection member 900, thereby enhancing the connection stability between the fixing member 700 and the optical fiber protection member 900.

[0178] In some embodiments, a sixth limiting surface 9121 may be formed on the inner wall of the first side plate portion 912. The sixth limiting surface 9121 may be correspondingly disposed with the second side surface 7121 of the fastener 700. The sixth limiting surface 9121 may contact and connect with the second side surface 7121 of the fastener 700 to define the position of the second sub-clamp portion 712 in the width direction of the fiber optic protection member 900.

[0179] In some embodiments, a fourth limiting surface 9124 may be formed on the inner wall of the first side plate portion 912. The fourth limiting surface 9124 may be correspondingly disposed with the first side surface 7112 of the first sub-connector portion 711. The fourth limiting surface 9124 may contact and connect with the first side surface 7112 of the first sub-connector portion 711 to define the position of the first sub-connector portion 711 in the width direction of the fiber optic protection member 900.

[0180] In some embodiments, a seventh limiting surface 9125 may be formed on the inner wall of the first side plate portion 912. The seventh limiting surface 9125 may be correspondingly provided with the third side surface 721 of the fastener 700. The seventh limiting surface 9125 may contact and connect with the third side surface 721 of the fastener 700, and may define the position of the second snap-fit ​​portion 720 in the width direction of the fiber optic protection member 900.

[0181] The sixth limiting surface 9121 can contact and connect with the second side surface 7121 of the fixing member 700, the fourth limiting surface 9124 can contact and connect with the first side surface 7112 of the first sub-clamping part 711, and the seventh limiting surface 9125 can contact and connect with the third side surface 721 of the fixing member 700, thereby limiting the position of the fixing member 700 in the width direction of the fiber optic protection member 900.

[0182] In some embodiments, the top of the first side plate portion 912 may be connected to the second limiting member 940. For example, the first side plate portion 912 may be a first side plate portion 912a, and the top of the first side plate portion 912a may be connected to the second limiting member 940.

[0183] like Figure 7a , Figure 7b and Figure 7c In some embodiments, the outer wall of the first side plate portion 912 may form a first outer side surface 9126, a second outer side surface 9128, a third outer side surface 9127, and a fourth outer side surface 9129. One end of the second outer side surface 9128 may be perpendicularly connected to the first outer side surface 9126, and the other end of the second outer side surface 9128 may be perpendicularly connected to one end of the third outer side surface 9127. The other end of the third outer side surface 9127 may be perpendicularly connected to the fourth outer side surface 9129, so that the first outer side surface 9126 may be arranged parallel to the third outer side surface 9127, and the second outer side surface 9128 may be arranged parallel to the fourth outer side surface 9129.

[0184] In some embodiments, the third outer surface 9127 may be recessed into the first outer surface 9126.

[0185] like Figure 7a , Figure 7b and Figure 7c In some embodiments, the second limiting member 940 is a second limiting member 940a. The second limiting member 940a may include a first limiting horizontal portion 942a. One side of the first limiting horizontal portion 942a may be connected to the top of the first side plate portion 912. The first limiting horizontal portion 942a may be disposed opposite to the first bottom plate portion 911.

[0186] In some embodiments, the second limiting member 940a may include a first limiting vertical portion 943a. One side of the first limiting vertical portion 943a may be connected to the other side of the first limiting horizontal portion 942a to form an L-shaped structure. The bottom of the first limiting vertical portion 943a may be connected to a first top surface 713, defining the position of the fixing member 700 in the height direction of the fiber optic protection member 900, such that the first top surface 713 is located below the first limiting vertical portion 943a.

[0187] In some embodiments, the thickness of the first limiting horizontal portion 942a is less than or equal to the thickness of the first limiting vertical portion 943a, so that when the first top surface 713 is connected to the bottom of the first limiting vertical portion 943a, there can be a gap between the first limiting horizontal portion 942a and the first top surface 713, providing assembly allowance and facilitating the assembly of the fastener.

[0188] In some embodiments, the second limiting member 940a may include a connecting portion 941a, the bottom of which may be connected to the top surface 9122a of the first side plate portion 912a, and the top side of the connecting portion 941a may be connected to one side of the first limiting horizontal portion 942a, so that the distance between the first limiting vertical portion 943a and the first bottom plate portion 911 is greater than or equal to the thickness of the fixing member 700, so that the first top surface 713 may be connected to the bottom of the first limiting vertical portion 943a.

[0189] In some embodiments, the second limiting member 940a and the first side plate portion 912a can be connected by adhesive bonding or thermal welding.

[0190] In some embodiments, the second limiting member 940a and the first side plate portion 912a can be integrally formed. For example, the top of the first side plate portion 912a protrudes inward to form the second limiting member 940a.

[0191] like Figure 7a , Figure 7b and Figure 7cAs shown, in some embodiments, the third fiber optic protective housing 920 may include a third base plate and two opposing third side plates. The bottom of one third side plate is connected to one side of the third base plate, and the bottom of the other third side plate is connected to the other side of the third base plate, so that the third fiber optic protective housing 920 is a U-shaped groove. One end of the third base plate may be connected to the first base plate 911, and one end of the third side plate may be connected to the first side plate 912, so that the third fiber optic protective housing 920 is connected to the first fiber optic protective housing 910.

[0192] In some embodiments, the outer wall of the third side plate portion may form a fifth outer side surface, one end of which may be perpendicularly connected to the fourth outer side surface 9129, so that the fifth outer side surface may be arranged parallel to the first outer side surface 9126 and the third outer side surface 9127.

[0193] In some embodiments, the fifth outer surface is recessed into the third outer surface 9127.

[0194] like Figure 7a , Figure 7b and Figure 7c As shown, in some embodiments, the second fiber optic protective housing 930 may include a second base plate portion 931 and two opposing second side plate portions 932. The bottom of one second side plate portion 932 is connected to one side of the second base plate portion 931, and the bottom of the other second side plate portion 932 is connected to the other side of the second base plate portion 931, so that the second fiber optic protective housing 930 is a U-shaped groove. One end of the second base plate portion 931 may be connected to the other end of the third base plate portion, and one end of the second side plate portion 932 may be connected to the other end of the third side plate portion, so that the second fiber optic protective housing 930 is connected to the third fiber optic protective housing 920. For example, the second fiber optic protective housing 930 can be the second fiber optic protective housing 930a, the second base plate portion 931 can be the second base plate portion 931a, the second side plate portion 932 can be the second side plate portion 932a, and the second fiber optic protective housing 930a can include the second base plate portion 931a and the second side plate portion 932a, with the second side plate portion 932a connected to the second base plate portion 931a.

[0195] In some embodiments, a support groove 9311 may be provided at one end of the second base plate portion 931 near the third base plate portion, and the optical fiber ribbon 400a is disposed on the support groove 9311 so that the support groove 9311 can support the optical fiber ribbon 400a, reducing the movement of the optical fiber ribbon 400a within the second optical fiber protective housing 930, thereby improving the stability of the optical fiber ribbon 400a. Furthermore, the design of the support groove 9311 can also help maintain the correct position of the optical fiber ribbon 400a within the optical module, preventing it from shifting due to vibration or other external factors, further ensuring the transmission quality of the optical signal.

[0196] In some embodiments, the support groove 9311 protrudes from the second bottom plate portion 931 of the second optical fiber protective housing 930 to provide a support point for the optical fiber ribbon 400a, so that the support groove 9311 can support the optical fiber ribbon 400a, effectively preventing the optical fiber ribbon 400a from making unnecessary contact with other components, thereby protecting the optical fiber ribbon 400a.

[0197] In some embodiments, the width of the support groove 9311 is smaller than the width of the second base plate portion 931 of the second optical fiber protective housing 930, so as to define the position of the optical fiber ribbon 400a in the width direction of the optical fiber protection member 900 and prevent the optical fiber ribbon 400a from swaying or shifting in the optical fiber protection member 900.

[0198] In some embodiments, the second base plate portion 931 may protrude upward to form a first support protrusion 9312. The side of the first support protrusion 9312 may connect to the inner wall of the second side plate portion 932a. The first support protrusion 9312 may be disposed below the circuit board 300. The top of the first support protrusion 9312 may contact and connect with the lower surface of the circuit board 300 to support the circuit board 300. For example, the first support protrusion 9312 may be a first support protrusion 9312a.

[0199] In some embodiments, the top of the first support protrusion 9312 may be connected to the first limiting member 950.

[0200] In some embodiments, the inner wall top of the second side plate portion 932 may protrude inward to form a limiting protrusion 933. The circuit board 300 may be disposed below the limiting protrusion 933 to define the position of the circuit board 300 in the height direction of the fiber optic protector 900. For example, the bottom of the limiting protrusion 933 may contact the upper surface of the circuit board 300. For example, the limiting protrusion 933 may be a limiting protrusion 933a, one end of which does not extend above the first support protrusion 9312a.

[0201] The top of the first support protrusion 9312 can contact and connect with the lower surface of the circuit board 300, and the bottom of the limiting protrusion 933 can contact and connect with the upper surface of the circuit board 300. This allows the circuit board 300 to be positioned between the first support protrusion 9312 and the limiting protrusion 933, thereby positioning the circuit board 300 in the height direction through the first support protrusion 9312 and the limiting protrusion 933. This design not only enhances the stability of the circuit board 300 within the optical module but also effectively prevents the circuit board 300 from shaking under vibration or other external factors, ensuring the overall reliability of the optical module.

[0202] In some embodiments, a third limiting surface 9321 may be formed on the inner wall of the second side plate portion 932. The third limiting surface 9321 may be disposed corresponding to the first end face of the circuit board 300. The third limiting surface 9321 may be in contact with the first end face of the circuit board 300 to define the position of the circuit board 300 in the longitudinal direction of the fiber optic protector 900.

[0203] In some embodiments, a fifth limiting surface 9322 may be formed on the inner wall of the second side plate portion 932. The fifth limiting surface 9322 may be disposed corresponding to the side surface of the circuit board 300. One end of the fifth limiting surface 9322 may be connected to the third limiting surface 9321. The fifth limiting surface 9322 may be in contact with the side surface of the circuit board 300 to define the position of the circuit board 300 in the width direction of the fiber optic protector 900.

[0204] like Figure 7a , Figure 7b and Figure 7c In some embodiments, the outer wall of the second side plate portion 932 may form a sixth outer side surface 9323, a seventh outer side surface 9324, and an eighth outer side surface 9325. One end of the sixth outer side surface 9323 may be perpendicularly connected to the fifth outer side surface, one end of the seventh outer side surface 9324 may be perpendicularly connected to the other end of the sixth outer side surface 9323, and the other end of the seventh outer side surface 9324 may be perpendicularly connected to one end of the eighth outer side surface 9325, so that the sixth outer side surface 9323 and the eighth outer side surface 9325 are arranged in parallel, and the fifth outer side surface and the seventh outer side surface 9324 are arranged in parallel.

[0205] In some embodiments, the seventh outer surface 9324 protrudes from the fifth outer surface.

[0206] In some embodiments, the outer wall of the second side plate portion 932a may form a ninth outer side surface 9326 and a tenth outer side surface 9327. One end of the ninth outer side surface 9326 may be perpendicularly connected to the eighth outer side surface 9325, and there is a gap between the other end of the ninth outer side surface 9326 and the tenth outer side surface 9327.

[0207] like Figure 7a , Figure 7b and Figure 7cAs shown, in some embodiments, the first limiting member 950 can be a first limiting member 950a. The bottom surface of the first limiting member 950a can be connected to the top surface of the first support protrusion 9312a, so that the first limiting member 950a can be correspondingly disposed with the first notch 310 of the circuit board 300, and the first limiting member 950a can be snapped into the first notch 310. The side surface of the first limiting member 950a can be connected to the fifth limiting surface 9322. The first limiting member 950a can be correspondingly disposed with the first notch 310 of the circuit board 300. The first limiting member 950a can be snapped into the first notch 310 of the circuit board 300 to define the position of the circuit board 300 from the length direction of the fiber optic protection member 900.

[0208] In some embodiments, the first limiting member 950a and the first supporting protrusion 9312a can be connected by adhesive bonding or thermal welding.

[0209] In some embodiments, the first limiting member 950a and the first support protrusion 9312a are integrally formed. For example, the first support protrusion 9312a protrudes upward to form the first limiting member 950a.

[0210] In some embodiments, the distance between the first end face of the circuit board 300 and the first notch 310 of the circuit board 300 and the distance between the third limiting surface 9321 and the first limiting member 950a are equal, so that the first end face of the circuit board 300 is in contact with the third limiting surface 9321 and the first limiting member 950a is engaged at the first notch 310 to further determine the position of the circuit board 300 in the length direction of the optical fiber protection member 900.

[0211] In some embodiments, the second fiber optic protective housing 930a may form a second notch 934. The second notch 934 may extend downward from the top surface of the second side plate portion 932a to the bottom surface of the second side plate portion 932a, so that the second notch 934 can divide the second side plate portion 932a into a first sub-side plate portion 9321a and a second sub-side plate portion 9322a. The second notch 934 may extend inward from one side surface of the second bottom plate portion 931a but not to the other side surface of the second bottom plate portion 931a.

[0212] In some embodiments, the height dimension of the first sub-side plate portion 9321a is greater than the height dimension of the second sub-side plate portion 9322a, so that the top of the second sub-side plate portion 9322a can protrude inward to form a limiting protrusion 933a.

[0245] In some embodiments, there may be a gap between the first sub-base plate 2211 and the second sub-base plate 2212, so that the first sub-base plate 2211, the second sub-base plate 2212, and the lower side plate 2022 can form a first storage through hole 2214. The first storage through hole 2214 can be correspondingly provided with the second outer bottom surface 962. The second outer bottom surface 962 can be snapped into the first storage through hole 2214. The provision of the first storage through hole 2214 not only facilitates the installation and removal of the second outer bottom surface 962, but also provides support and positioning for the fiber optic protection component 900 to a certain extent, ensuring its stability and reliability in the optical module.

[0246] In some embodiments, there may be a gap between the second sub-base plate 2212 and the third sub-base plate 2213, so that the second sub-base plate 2212, the third sub-base plate 2213, and the lower side plate 2022 can form a second storage through hole 2215. The second storage through hole 2215 can be correspondingly provided with the fourth outer bottom surface 964. The fourth outer bottom surface 964 can be snapped into the second storage through hole 2215. The provision of the second storage through hole 2215 not only facilitates the installation and removal of the fourth outer bottom surface 964, but also provides support and positioning for the fiber optic protection component 900 to a certain extent, ensuring its stability and reliability in the optical module.

[0247] In some embodiments, the inner wall of the lower side plate 2022 of the lower housing 202 can form a first snap-fit ​​surface 2221, which can be in contact with the first outer side surface 9126 of the optical fiber protection component 900.

[0248] In some embodiments, the inner wall of the lower side plate 2022 of the lower housing 202 can protrude inward to form a first snap-fit ​​protrusion 2222. One side of the first snap-fit ​​protrusion 2222 can contact and connect with the second outer side 9128, and the other side of the first snap-fit ​​protrusion 2222 can contact and connect with the third outer side 9127.

The second snap-fit ​​protrusion 2223 may include a first side, a second side, and a third side arranged sequentially. The first side of the second snap-fit ​​protrusion 2223 may contact and connect with a fourth outer side 9129, the second side of the second snap-fit ​​protrusion 2223 may contact and connect with a fifth outer side 921, and the third side of the second snap-fit ​​protrusion 2223 may contact and connect with a sixth outer side 9323.

[0250] In some embodiments, the inner wall of the lower side plate 2022 of the lower housing 202 can protrude inward to form a third snap-fit ​​protrusion 2224. One side of the third snap-fit ​​protrusion 2224 can contact and connect with the seventh outer side 9324, and the other side of the third snap-fit ​​protrusion 2224 can contact and connect with the eighth outer side 9325.

[0251] In some embodiments, the inner wall of the lower side plate 2022 of the lower housing 202 may form a second snap-fit ​​surface 2225. The second snap-fit ​​surface 2225 may contact and connect with the ninth outer side surface 9326.

[0252] In some embodiments, the inner wall of the lower side plate 2022 of the lower housing 202 protrudes inward to form a fourth snap-fit ​​protrusion 2226. The fourth snap-fit ​​protrusion 2226 can snap onto the second notch 934 to increase the contact area between the lower housing 202 and the fiber optic protection component 900, thereby improving the connection stability between the lower housing 202 and the fiber optic protection component 900. In addition, the fourth snap-fit ​​protrusion 2226 also has a positioning function, so that the lower housing 202 can accurately and quickly align with the fiber optic protection component 900, avoiding installation misalignment or insecure installation.
