[0062] Next, some embodiments of the present disclosure will be clearly and detailedly described in conjunction with the accompanying drawings. However, the described embodiments are only some embodiments of the present disclosure, rather than all embodiments. Based on the embodiments provided by the present disclosure, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present disclosure.

[0064] Optical communication technology establishes information transmission between information processing devices. Optical communication technology loads information onto light and uses the propagation of light to achieve information transmission. The light loaded with information is an optical signal. The optical signal propagates in the information transmission device, which can reduce the loss of optical power and achieve high-speed, long-distance, and low-cost information transmission. The information that information processing devices can process exists in the form of electrical signals. Optical network terminals / gateways, routers, switches, mobile phones, computers, servers, tablet computers, and televisions are common information processing devices, and optical fibers and optical waveguides are common information transmission devices.

[0065] The mutual conversion between optical signals and electrical signals between information processing devices and information transmission devices is achieved through an optical module. For example, an optical fiber is connected to the optical signal input end and / or optical signal output end of the optical module, and an optical network terminal is connected to the electrical signal input end and / or electrical signal output end of the optical module; the first optical signal from the optical fiber is transmitted into the optical module, the optical module converts the first optical signal into a first electrical signal, and the optical module transmits the first electrical signal into the optical network terminal; the second electrical signal from the optical network terminal is transmitted into the optical module, the optical module converts the second electrical signal into a second optical signal, and the optical module transmits the second optical signal into the optical fiber. Since information processing devices can be interconnected through an electrical signal network, at least one type of information processing device needs to be directly connected to the optical module, and it is not necessary for all types of information processing devices to be directly connected to the optical module. The information processing device directly connected to the optical module is called the host computer of the optical module.

[0066] Figure 1 A partial architecture diagram of an optical communication system provided according to some embodiments of the present disclosure. AsFigure 1 As shown, a part of the optical communication system 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.

[0067] One end of the optical fiber 101 extends towards the remote information processing device 1000, and the other end is connected to the optical interface of the optical module 200. Total internal reflection can occur in the optical fiber 101. The optical signal can almost maintain its original optical power during propagation in the direction of total internal reflection. The optical signal undergoes multiple total internal reflections in the optical fiber 101, transmitting the optical signal from the direction of the remote information processing device 1000 into the optical module 200, or propagating the optical signal from the optical module 200 towards the remote information processing device 1000, achieving long-distance information transmission with low power loss.

[0068] The number of optical fibers 101 can be one or multiple (two or more); the optical fiber 101 and the optical module 200 can be connected in a pluggable and detachable manner, or in a fixed connection.

[0069] The host computer 100 has an optical module interface 102, which is configured to connect to the optical module 200, so that a unidirectional / bidirectional electrical signal connection is established between the host computer 100 and the optical module 200; the host computer 100 is configured to provide a data signal to the optical module 200, or receive a data signal from the optical module 200, or monitor and control the working state of the optical module 200.

[0070] The host computer 100 has external electrical interfaces, such as a Universal Serial Bus (USB) interface and a network cable interface 104. The external electrical interfaces can be connected to an electrical signal network. For example, the network cable interface 104 is configured to connect to the network cable 103, so that a unidirectional / bidirectional electrical signal connection is established between the host computer 100 and the network cable 103.

[0071] An Optical Network Unit (ONU), an Optical Line Terminal (OLT), an Optical Network Terminal (ONT), and a data center server are common host computers.

[0072] One end of the network cable 103 is connected to the local information processing device 2000, and the other end is connected to the host computer 100. The network cable 103 establishes an electrical signal connection between the local information processing device 2000 and the host computer 100.

[0073] Exemplarily, the third electrical signal sent by the local information processing device 2000 is transmitted into the host computer 100 through the network cable 103. The host computer 100 generates a second electrical signal based on the third electrical signal. The second electrical signal from the host computer 100 is transmitted into the optical module 200. The optical module 200 converts the second electrical signal into a second optical signal. The optical module 200 transmits the second optical signal into the optical fiber 101, and the second optical signal is transmitted in the optical fiber 101 towards the remote information processing device 1000.

[0074] Exemplarily, the first optical signal from the direction of the remote information processing device 1000 propagates through the optical fiber 101. The first optical signal from the optical fiber 101 is transmitted into the optical module 200. The optical module 200 converts the first optical signal into a first electrical signal. The optical module 200 transmits the first electrical signal into the host computer 100. The host computer 100 generates a fourth electrical signal based on the first electrical signal. The host computer 100 transmits the fourth electrical signal into the local information processing device 2000.

[0075] The optical module is a tool for realizing the mutual conversion between optical signals and electrical signals. In the above process of converting optical signals and electrical signals, the information does not change, but the encoding and decoding methods of the information can change.

[0076] Figure 2 FIG. is a partial structural diagram of a host computer provided according to some embodiments of the present disclosure. In order to clearly show the connection relationship between the optical module 200 and the host computer 100, Figure 2 only the structure related to the host computer 100 and the optical module 200 is shown. As Figure 2 shown, the host computer 100 further includes a PCB circuit board 105 disposed in the housing, a cage 106 disposed on the surface of the PCB circuit board 105, a radiator 107 disposed on the cage 106, and an electrical connector (not shown in the figure) disposed inside the cage 106. The radiator 107 has a raised structure for increasing the heat dissipation area, and the fin-like structure is a common raised structure.

[0077] The optical module 200 is inserted into the cage 106 of the host computer 100. The cage 106 fixes the optical module 200. The heat generated by the optical module 200 is conducted to the cage 106 and then diffused through the radiator 107. After the optical module 200 is inserted into the cage 106, the electrical interface of the optical module 200 is connected to the electrical connector inside the cage 106.

[0078] Figure 3 FIG. is a structural diagram of an optical module provided according to some embodiments of the present disclosure, Figure 4 FIG. is an exploded view of an optical module provided according to some embodiments of the present disclosure. As Figure 3 and Figure 4As shown, the optical module 200 includes a shell, a circuit board 300 disposed within the shell, an optical transceiver component 400, and an optical receiver component 500. However, the present disclosure is not limited thereto. In some embodiments, the optical module 200 includes one of the optical transceiver component 400 and the optical receiver component 500.

[0079] The shell includes an upper shell 201 and a lower shell 202. The upper shell 201 covers the lower shell 202 to form the above-mentioned shell having two openings 204 and 205; the outer contour of the shell generally presents a square body.

[0080] In some embodiments, the lower shell 202 includes a bottom plate 2021 and two lower side plates 2022 located on both sides of the bottom plate 2021 and perpendicular to the bottom plate 2021; the upper shell 201 includes a cover plate 2011, and the cover plate 2011 covers the two lower side plates 2022 of the lower shell 202 to form the above-mentioned shell.

[0081] In some embodiments, the lower shell 202 includes a bottom plate 2021 and two lower side plates 2022 located on both sides of the bottom plate 2021 and perpendicular to the bottom plate 2021; the upper shell 201 includes a cover plate 2011 and two upper side plates located on both sides of the cover plate 2011 and perpendicular to the cover plate 2011. The two upper side plates are combined with the two lower side plates 2022 to achieve the upper shell 201 covering the lower shell 202.

[0082] The direction in which the line connecting the two openings 204 and 205 is located may be consistent with the length direction of the optical module 200 or may not be consistent with the length direction of the optical module 200. For example, the opening 204 is located at the end of the optical module 200 ( Figure 3 the right end), and the opening 205 is also located at the end of the optical module 200 ( Figure 3 the left end). Alternatively, the opening 204 is located at the end of the optical module 200, while the opening 205 is located at the side of the optical module 200. The opening 204 is an electrical interface, and the gold finger 301 of the circuit board 300 extends out from the electrical interface and is inserted into the electrical connector of the host computer; the opening 205 is an optical port and is configured to access the optical fiber 101 so that the optical fiber 101 connects to the optical transmitting component and / or the optical receiving component in the optical module 200.

[0083] Adopting the assembly method of combining the upper shell 201 and the lower shell 202 facilitates the installation of components such as the circuit board 300, the optical transceiver component 400, and the optical receiver component 500 into the above-mentioned shell. The upper shell 201 and the lower shell 202 can encapsulate and protect the shapes of these components. In addition, when assembling components such as the circuit board 300, the optical transmitting component, and the optical receiving component, it is convenient for the deployment of the positioning components, heat dissipation components, and electromagnetic shielding components of these devices, which is conducive to the automated implementation of production.

[0084] In some embodiments, the upper housing 201 and the lower housing 202 are made of a metal material, which is conducive to achieving electromagnetic shielding and heat dissipation.

[0085] In some embodiments, the optical module 200 further includes an unlocking component 800 located outside its housing. The unlocking component 800 is configured to achieve a fixed connection between the optical module 200 and the host computer, or to release the fixed connection between the optical module 200 and the host computer.

[0086] For example, the unlocking component 800 is located outside the two lower side plates 2022 of the lower housing 202 and includes a latching component that matches the cage 106 of the host computer. When the optical module 200 is inserted into the cage 106, the latching component of the unlocking component 800 fixes the optical module 200 in the cage 106; when the unlocking component 800 is pulled, the latching component of the unlocking component 800 moves accordingly, thereby changing the connection relationship between the latching component and the host computer to release the latching and fixing connection between the optical module 200 and the host computer, so that the optical module 200 can be withdrawn from the cage 106.

[0087] The circuit board 300 includes circuit traces, electronic components, and chips, etc. The electronic components and chips are connected together according to the circuit design through the circuit traces to achieve functions such as power supply, electrical signal transmission, and grounding. The electronic components may include, for example, capacitors, resistors, triodes, and Metal-Oxide-Semiconductor Field-Effect Transistors (MOSFETs). The chips may include, for example, a Microcontroller Unit (MCU), a laser driver chip, a Transimpedance Amplifier (TIA), a limiting amplifier, a Clock and Data Recovery (CDR) chip, a power management chip, and a Digital Signal Processing (DSP) chip.

[0088] The circuit board 300 is generally a rigid circuit board. Due to its relatively hard material, the rigid circuit board can also achieve a bearing function. For example, the rigid circuit board can stably bear the above-mentioned electronic components and chips; the rigid circuit board is also convenient for inserting into the electrical connectors in the host computer cage.

[0089] Of course, flexible circuit boards are also used in some optical modules. The flexible circuit boards are generally used in cooperation with rigid circuit boards as a supplement to the rigid circuit boards.

[0090] The light emitting component and / or the light receiving component are located on the side of the circuit board 300 away from the gold finger 301; in some embodiments, the light emitting component and the light receiving component are physically separated from the circuit board 300 respectively, and then electrically connected to the circuit board 300 through corresponding flexible circuit boards or electrical connectors respectively; in some embodiments, the optical transceiver component can be directly disposed on the circuit board 300, and can be disposed on the surface of the circuit board or on the side of the circuit board.

As Figure 10As shown, the optical fiber adapter 600 may include an optical fiber protection portion 650. A part of the optical fiber protection portion 650 is located inside the optical fiber plug 620, and a part of the optical fiber protection portion 650 protrudes outside the optical fiber plug 620 to protect the bending of the optical fiber ribbon 500 and avoid breakage due to excessive bending. The optical fiber ribbon 500 passes through the optical fiber socket 653 of the optical fiber protection portion 650. The optical fiber socket 653 runs through the left - right length direction of the optical fiber protection portion 650. The optical fiber ribbon 500 can pass through the optical fiber socket 653 and enter the inside of the clamping jaw.

[0104] The optical fiber protection portion 650 may include an embedding area 651. The embedding area 651 is embedded inside the optical fiber plug 620 to block the notch of the optical fiber plug 620.

[0105] The optical fiber protection portion 650 may include an exposed area 652. The exposed area 652 is exposed outside the optical fiber plug 620. The outer wall of the embedding area 651 may protrude beyond the outer wall of the exposed area 652, that is, the width dimension of the embedding area 651 in the up - down direction may be greater than the width dimension of the exposed area 652 in the up - down direction; the length dimension of the embedding area 651 in the front - back direction may be greater than the length dimension of the exposed area 652 in the front - back direction. The embedding area 651 may be connected to the optical fiber plug 620 by interference fit.

[0106] The optical fiber protection portion 650 may be made of rubber material, and the optical fiber protection portion 650 may have compressible characteristics. The optical fiber protection portion 650 may be a flexible protection material.

[0107] Figure 11 It is a schematic diagram of the optical fiber plug structure provided according to some embodiments of the present application. As Figure 11 shown, the optical fiber plug 620 may include a ferrule 621. The ferrule 621 is embedded inside the clamping jaw 610, and the clamping jaw 610 can protect the ferrule 621.

[0108] The optical fiber plug 620 may include a fixing portion 622. The outer wall of the fixing portion 622 may protrude beyond the outer wall of the ferrule 621, that is, the width dimension of the fixing portion 622 in the up - down direction may be greater than the width dimension of the ferrule 621 in the up - down direction; the length dimension of the fixing portion 622 in the front - back direction may be greater than the length dimension of the ferrule 621 in the front - back direction.

[0109] The three - side surface 6223 of the fixing portion 622 facing away from the ferrule 621 contacts one end surface of the fixing member 630.

[0110] In some embodiments, the outer wall of the fixing member 630 may protrude beyond the outer wall of the fixing portion 622, that is, the width dimension of the fixing member 630 in the up - down direction may be greater than the width dimension of the fixing portion 622 in the up - down direction; the length dimension of the fixing member 630 in the front - back direction may be greater than the length dimension of the fixing portion 622 in the front - back direction.

[0111] On three side faces 6223 of the ferrule of the fiber optic plug 620, there may be provided pin holes 6222 which penetrate through the fixing part 622 and the ferrule 621 of the fiber optic plug 620. When the fiber optic plug 620 is inserted into the light passing hole 6130 of the clamping jaw 610, the fiber optic plug 620 extends into the light passing hole 6130. The insertion part 6430 at one end of the pin 640 penetrates through the second through hole 631 and the pin hole 6222, and enters the light passing hole 6130 after passing through the fixing part 622 and the ferrule 621.

[0112] In some embodiments, protection holes 6221 may be provided on the three side faces 6223 of the ferrule. One end of the optical fiber protection part 650 may extend into the fixing part 622 through the protection hole 6221. The optical fiber protection part 650 may be connected with the protection hole 6221 in an interference fit. In some embodiments, the embedding area 651 is in interference fit with the protection hole 6221. For the convenience of installation and fixation, the hardness of the optical fiber protection part 650 may be less than the hardness of the fiber optic plug 620.

[0113] In some embodiments, the hardness of the optical fiber protection part 650 may be less than the hardness of the fixing part 622.

[0114] Figure 12 It is a schematic structural diagram of a fixing part provided according to an embodiment of the present application. Figure 13 It is a schematic structural diagram of a combined cross-section of a fixing part, an optical fiber protection part, a fiber optic plug and a pin provided according to an embodiment of the present application. As Figure 12 and Figure 13 shown, the fixing part 630 may include an avoidance hole 633, and the optical fiber protection part 650 may enter the fiber optic plug 620 through the avoidance hole 633. The optical fiber protection part 650 may enter the fixing part 622 through the avoidance hole 633.

[0115] The optical fiber ribbon may pass through the avoidance hole 633 and be inserted into the fixing part 622 to realize the optical fiber connection between the optical transceiver component and the fiber optic adapter 600.

[0116] The optical fiber protection part 650 may be connected with the avoidance hole 633 in an interference fit, so that the optical fiber protection part 650 fills the avoidance hole 633, reduces the gap between the avoidance hole 633 and the optical fiber protection part 650, and effectively prevents dust from entering the optical module through the gap between the avoidance hole 633 and the optical fiber protection part 650. For the convenience of installation and fixation, the hardness of the optical fiber protection part 650 may be less than the hardness of the fixing part 630.

[0117] A first through hole 632 may be provided on the fixing part 630.

[0118] The fixing member 630 may be provided with a second through hole 631, and the first through hole 632 communicates with the second through hole 631.

[0119] The fixing member 630 may be disposed between the side wall of the fiber optic plug 620 and the inner wall of the claw.

[0120] In some embodiments, for the convenience of taking the pin 640, the diameter of the exposed portion 641 may be larger than that of the first through hole 632. Thus, when the pin 640 is inserted into the pin hole 6222 of the fiber optic plug 620 through the first through hole 632, the exposed portion 641 is exposed outside the fixing member 630. At this time, the pin 640 can move left and right in the pin hole 6222 and the first through hole 632; then the fixing member 630 is moved, and the connecting portion 6420 is snapped into the second through hole 631. At this time, the pin 640 cannot move left and right in the second through hole 631, so that the pin 640 is fixed to the fixing member 630.

[0121] In some embodiments, the fiber optic plug 620 may be an MT male head, and the plug of the external fiber optic plug 700 is a corresponding MT female head. That is, after the pin 640 is fixed to the fiber optic plug 620, the end of the pin 640 facing away from the exposed portion 641 protrudes from the fiber optic plug 620. Thus, when the external fiber optic plug 700 is inserted into the claw 610, the protruding pin 640 is inserted into the jack on the end face of the external fiber optic plug 700 to achieve the positioning connection between the fiber optic plug 620 and the external fiber optic plug 700.

[0158] Figure 18 FIG. 10 is a schematic diagram of a first angle structure of a clamping jaw lower housing in an optical fiber adapter provided according to an embodiment of the present application. Figure 19 FIG. 11 is a schematic diagram of a second angle structure of a clamping jaw lower housing in an optical fiber adapter provided according to an embodiment of the present application. Figure 20 FIG. 12 is a schematic cross-sectional structure diagram of a clamping jaw lower housing in an optical fiber adapter provided according to an embodiment of the present application. As Figure 18 、 Figure 19 and Figure 20 shown, in some embodiments, the fixing member 6111 may be a cavity structure with both ends open, one open end of which is configured as an entry channel for an external optical fiber, and the other opening communicates with the light passing hole of the support member 6112.

One end of the first elastic buckle 6160 is fixedly connected to the fixing member 6111. Thus, the first elastic buckle 6160 can open and close with the fixed end as the origin, so that the first elastic buckle 6160 expands outward or clamps inward.

After the external optical fiber reaches the preset position, the second elastic buckle 6161 clamps inwards.

The side baffle 6114 abuts against the shielding groove 6151, which can increase the contact area between the upper claw housing 612 and the lower claw housing 611, and can increase the path for dust or air to enter the inside of the light passing hole from the gap between the upper claw housing 612 and the lower claw housing 611. The side baffle 6114 abuts against the shielding groove 6151, which can increase the sealing performance of the optical fiber adapter.

[0202] The side baffle 6114 abuts against the shielding groove 6151, which can increase the contact area between the upper claw housing 612 and the lower claw housing 611, reduce the deformation of the upper claw housing 612 during installation after being stressed, and can increase the sealing performance of the optical fiber adapter.

[0203] The side baffle 6114 can be arranged between the inner walls of the first support side plate 6610 and the second support side plate 6620.

[0209] In some embodiments, a first upper housing support portion 6615 may be provided on the first support side plate 6610. The first upper housing support portion 6615 protrudes relative to the lower surface of the first support side plate 6610, increasing the distance from the upper housing cover plate 615 of the upper housing of the claw, tightening the upper housing cover plate 615, and preventing the upper housing cover plate 615 from separating from the lower housing of the claw 611.

The side wall of the exposed area 652 may abut against the inner wall of the first lower housing baffle 6643, and the first lower housing baffle 6643 may limit the movement of the exposed area 652 in the front-rear direction. The upper surface of the first lower housing baffle 6643 may be lower than or equal to the lowest point of the lower surface of the pin 640, so as to avoid affecting the installation and taking of the pin 640.

[0216] The upper surface of the first lower housing baffle 6643 may be lower than or equal to the lowest point of the lower surface of the exposed portion 641, so as to avoid affecting the installation and taking of the pin 640.

[0223] The second lower housing baffle 66430 may be connected to the second support side plate 6620 to seal the optical port and prevent dust from entering.

[0224] For convenience of description, the rightmost end of the light-passing hole formed by the upper jaw shell 612 and the lower jaw shell 611 is called the right light-passing hole. The fixing member 630 abuts against the inner wall forming the right light-passing hole. The width of the fixing member 630 in the front-back direction is greater than the width of the right light-passing hole in the front-back direction, which can prevent dust from entering the ferrule through the gap in the front-back direction between the right light-passing hole and the exposed area 652.

[0225] The width of the fixing member 630 in the up-down direction is greater than the width of the right light-passing hole in the up-down direction, which can prevent dust from entering the ferrule through the gap in the up-down direction between the right light-passing hole and the exposed area 652.

[0226] In some embodiments, the width of the fixing portion 622 in the front-back direction is greater than the width of the right light-passing hole in the front-back direction, which can prevent dust from entering the ferrule through the gap in the front-back direction between the right light-passing hole and the exposed area 652.

[0227] The width of the fixing portion 622 in the up-down direction is greater than the width of the right light-passing hole in the up-down direction, which can prevent dust from entering the ferrule through the gap in the up-down direction between the right light-passing hole and the exposed area 652.

[0228] In some embodiments of the present application, one end of the fiber protection portion 650 of the fiber protection portion 650 can first extend into the fixing portion 622 through the protection hole 6221.

[0229] The ferrule 640 can be connected to the fixing member 630. The connecting portion 6420 is snapped into the second through hole 631, and the exposed portion 641 is exposed outside the fixing member 630. Then the insertion portion 6430 is inserted into the ferrule hole 6222. The insertion portion 6430 at one end of the ferrule 640 penetrates through the second through hole 631 and the ferrule hole 6222, and enters the light-passing hole 6130 after passing through the fixing portion 622 and the ferrule 621. The exposed area 652 is exposed to the right side of the fixing member 630 through the avoidance hole 633. The fiber protection portion 650 can be connected with the avoidance hole 633 in an interference fit manner, so that the fiber protection portion 650 is filled in the avoidance hole 633, reducing the gap between the avoidance hole 633 and the fiber protection portion 650, and effectively preventing dust from entering the optical module through the gap between the avoidance hole 633 and the fiber protection portion 650.

[0230] For convenience of description, the plug assembly may include a ferrule 640, a fixing member 630, an optical fiber plug 620, and a fiber protection portion 650.

[0231] When the plug assembly is inserted into the lower jaw shell 611 from above the opening of the support member 6112, the lower surface of the optical fiber plug 620 can be inserted obliquely along the transition portion 664; the ferrule side surface 6224 of the fixing portion 622 can be embedded in the right side of the first support step 6612, and the step surface between the ferrule side surface 6224 of the fixing portion 622 and the ferrule 621 abuts against the first support step 6612; the fixing portion 622 can slide down along the inclined surface of the first support step 6612 into the jaw.

[0232] The two side surfaces 6225 of the ferrule of the fixing part 622 are embedded in the right side of the second support step 66120, and the step surface between the two side surfaces 6225 of the ferrule of the fixing part 622 and the ferrule 621 abuts against the second support step 66120. The fixing part 622 can slide downwards along the inclined slope at the second support step 66120 into the claw.

[0233] The fiber optic plug 620 is inserted from top to bottom through the upper opening of the support member 6112 into the lower claw housing 611. During the installation process, one side surface 6224 of the ferrule of the fixing part 622 contacts the first support side plate 6610 of the lower claw housing 611. The two side surfaces 6225 of the ferrule of the fixing part 622 contact the second support side plate 6620 of the lower claw housing 611. The left side surface of the fixing part 622 abuts against the first support step 6612 and the second support step 66120, defining the relative position of the fixing part 622 and the lower claw housing 611 in the left - right direction. The inclined setting of the first support step 6612 facilitates the installation of the fiber optic plug 620. The fiber optic ribbon 500 can pass through the fiber optic socket 653 into the inside of the claw.

[0234] The position of the left side wall of the bottom plate groove 6642 in the left - right direction is consistent with the position of the first support step 6612 in the left - right direction. During the process of inserting the fiber optic plug 620 from the opening of the support member 6112 into the claw, one side surface 6224 of the ferrule of the fixing part 622 of the fiber optic plug is embedded in the right side of the first support step 6612, and the step surface between one side surface 6224 of the ferrule of the fixing part 622 and the ferrule 621 abuts against the first support step 6612; until the bottom surface of the fixing part 622 is embedded in the bottom plate groove 6642.

[0235] When the bottom surface of the fixing part 622 is embedded in the bottom plate groove 6642, the exposed area 652 of the fiber optic protection part 650 is located between the first lower shell baffle 6643 and the second lower shell baffle 66430.

[0236] After the optical fiber component is fixed under the claw lower shell 611, the claw upper shell 612 is inserted into the claw lower shell 611 from the right end. The first upper shell arm 6128 can slide into the claw lower shell along the upper surface of the first support side plate 6610 from the right end. The second upper shell arm 61280 can slide into the claw lower shell along the upper surface of the second support side plate 6620 from the right end. Until the side baffle 6114 abuts against the shielding groove 6151, the sealing performance of the optical fiber adapter can be improved. The first connecting protrusion 6611 is located in the first mounting hole 6141 to realize the fixation of the claw upper shell 612 and the claw lower shell 611. The second connecting protrusion 6621 is located in the second mounting hole 6142 to realize the fixation of the claw upper shell 612 and the claw lower shell 611. The upper shell cover plate 615 of the claw upper shell 612 covers the upper opening of the claw lower shell 611, so that the claw upper shell and the claw lower shell form a sealed structure with a light passing hole only in the left-right direction, which can effectively prevent dust from entering the claw from the up-down and front-back directions. The optical fiber protection part 650 can be connected with the avoidance hole 633 in an interference fit manner, so that the optical fiber protection part 650 is filled in the avoidance hole 633, reducing the gap between the avoidance hole 633 and the optical fiber protection part 650, effectively preventing dust from entering the optical module through the gap between the avoidance hole 633 and the optical fiber protection part 650, and can effectively prevent dust from entering the claw from the left-right direction.
