[0051] In optical communication technology, in order to establish information transmission between information processing devices, it is necessary to load information onto light and use the propagation of light to achieve information transmission. Here, the light loaded with information is an optical signal. When optical signals are transmitted in information transmission equipment, the loss of optical power can be reduced, so high-speed, long-distance, and low-cost information transmission can be achieved. The signals that information processing equipment can recognize and process are electrical signals. Information processing equipment usually includes optical network terminals (Optical Network Unit, ONU), gateways, routers, switches, mobile phones, computers, servers, tablets, televisions, etc., and information transmission equipment usually includes optical fibers and optical waveguides.

[0052] The optical module can realize the mutual conversion between optical signals and electrical signals between information processing equipment and information transmission equipment. For example, at least one of the optical signal input end or the optical signal output end of the optical module is connected to an optical fiber, and at least one of the electrical signal input end or the electrical signal output end of the optical module is connected to an optical network terminal; the first optical signal from the optical fiber is transmitted to the optical module, and the optical module converts the first optical signal into a first electrical signal, and transmits the first electrical signal to the optical network terminal; the second electrical signal from the optical network terminal is transmitted to the optical module, and the optical module converts the second electrical signal into a second optical signal, and transmits the second optical signal to the optical fiber. Since multiple information processing devices can transmit information through electrical signals, at least one of the multiple information processing devices needs to be directly connected to the optical module, and all information processing devices do not need to be directly connected to the optical module. Here, the information processing device directly connected to the optical module is called the upper computer of the optical module. In addition, the optical signal input end or the optical signal output end of the optical module can be called an optical port, and the electrical signal input end or the electrical signal output end of the optical module can be called an electrical port.

[0053] Figure 1 FIG. 1 is a partial architecture 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 .

[0054] One end of the optical fiber 101 extends toward the remote information processing device 1000, and the other end of the optical fiber 101 is connected to the optical module 200 through the optical port of the optical module 200. The optical signal can be totally reflected in the optical fiber 101, and the propagation of the optical signal in the total reflection direction can almost maintain the original optical power. The optical signal undergoes multiple total reflections in the optical fiber 101 to transmit the optical signal from the remote information processing device 1000 to the optical module 200, or to transmit the optical signal from the optical module 200 to the remote information processing device 1000, thereby realizing long-distance, low-power loss information transmission.

[0055] The optical communication system may include one or more optical fibers 101, and the optical fibers 101 are detachably connected 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 working state of the optical module 200.

[0056] The host computer 100 includes a substantially 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 establish a unidirectional or bidirectional electrical signal connection.

[0057] The host computer 100 also includes an external electrical interface, which can be connected to an electrical signal network. For example, the external electrical interface includes a Universal Serial Bus (USB) interface or a network cable interface 104, and the network cable interface 104 is configured to access the network cable 103 so that the host computer 100 establishes a unidirectional or bidirectional electrical signal connection with the network cable 103. One end of the network cable 103 is connected to the local information processing device 2000, and the other end of the network cable 103 is connected to the host computer 100, so as to establish an electrical signal connection between the local information processing device 2000 and the host computer 100 through the network cable 103. For example, the third electrical signal sent by the local information processing device 2000 is transmitted to the host computer 100 through the network cable 103, and the host computer 100 generates a second electrical signal according to the third electrical signal. The second electrical signal from the host computer 100 is transmitted to the optical module 200, and the optical module 200 converts the second electrical signal into a second optical signal, and transmits the second optical signal to the optical fiber 101, and the second optical signal is transmitted to the remote information processing device 1000 in the optical fiber 101. For example, the first optical signal from the remote information processing device 1000 is transmitted through the optical fiber 101, and the first optical signal from the optical fiber 101 is transmitted to the optical module 200, and the optical module 200 converts the first optical signal into a first electrical signal, and the optical module 200 transmits the first electrical signal to the host computer 100, and the host computer 100 generates a fourth electrical signal according to the first electrical signal, and transmits the fourth electrical signal to the local information processing device 2000. It should be noted that the optical module is a tool for realizing the mutual conversion between optical signals and electrical signals. During the conversion process between the optical signals and electrical signals, the information does not change, but the encoding and decoding methods of the information can change.

[0058] In addition to the optical network terminal, the host computer 100 also includes an optical line terminal (OLT), an optical network device (ONT), or a data center server.

[0059] Figure 2 FIG. 1 is a partial structural diagram of a host computer according to some embodiments. In order 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. Figure 2As shown, the host computer 100 further includes a PCB circuit board 105 disposed in the housing, a cage 106 disposed on the surface of the PCB circuit board 105, a heat sink 107 disposed on the cage 106, and an electrical connector disposed inside the cage 106. The electrical connector is configured to access the electrical port of the optical module 200; the heat sink 107 has a protruding structure such as fins to increase the heat dissipation area.

[0060] The optical module 200 is inserted into the cage 106 of the host computer 100, and the cage 106 fixes the optical module 200. The heat generated by the optical module 200 is transferred to the cage 106 and then diffused through the heat sink 107. After the optical module 200 is inserted into the cage 106, the electrical port of the optical module 200 is connected to the electrical connector inside the cage 106, so that the optical module 200 establishes a bidirectional electrical signal connection with the host computer 100. In addition, the optical port of the optical module 200 is connected to the optical fiber 101, so that the optical module 200 establishes a bidirectional optical signal connection with the optical fiber 101.

[0061] Figure 3 The present invention is a structural diagram of an optical module provided according to some embodiments. Figure 4 FIG. 1 is an exploded view of an optical module provided according to some embodiments. Figure 3 and Figure 4 As shown, the optical module 200 includes a shell, a circuit board 300 disposed in the shell, and an optical transceiver component 900 .

[0062] The housing comprises an upper housing 201 and a lower housing 202 . The upper housing 201 covers the lower housing 202 to form the housing having two openings 204 and 205 . The outer contour of the housing is generally a square body.

[0063] 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 arranged 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.

[0064] 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 vertically arranged with 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 vertically arranged with the cover plate 2011, and the two upper side plates are combined with the two lower side plates 2022 to realize that the upper shell 201 covers the lower shell 202.

[0065] The direction of the line connecting the two openings 204 and 205 may be consistent with the length direction of the optical module 200, or may be inconsistent with the length direction of the optical module 200. For example, the opening 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 ( Figure 3 Alternatively, the opening 204 is located at the end of the optical module 200, and the opening 205 is located at the side of the optical module 200. The opening 204 is an electrical port, and the gold finger of the circuit board 300 extends from the electrical port and is inserted into the electrical connector of the host computer 100; the opening 205 is an optical port, which is configured to access the external optical fiber 101 so that the optical fiber 101 is connected to the optical transceiver component 900 in the optical module 200.

[0066] The upper housing 201 and the lower housing 202 are combined to facilitate the installation of the circuit board 300 and the optical transceiver component 900 into the housing, and the upper housing 201 and the lower housing 202 can encapsulate and protect the components. In addition, when assembling the circuit board 300 and the optical transceiver component 900, the positioning components, heat dissipation components, and electromagnetic shielding components of these components are conveniently arranged, which is conducive to automated production.

[0067] In some embodiments, the upper shell 201 and the lower shell 202 are made of metal materials to facilitate electromagnetic shielding and heat dissipation.

[0068] In some embodiments, the optical module 200 further includes an unlocking component 600 located outside its housing. The unlocking component 600 is configured to achieve a fixed connection between the optical module 200 and the host computer, or to release the fixed connection between the optical module 200 and the host computer.

[0069] 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 snap-fit ​​component that matches the cage 106 of the host computer 100. When the optical module 200 is inserted into the cage 106, the snap-fit ​​component of the unlocking component 600 fixes the optical module 200 in the cage 106; when the unlocking component 600 is pulled, the snap-fit ​​component of the unlocking component 600 moves accordingly, thereby changing the connection relationship between the snap-fit ​​component and the host computer, so as to release the fixation of the optical module 200 and the host computer, so that the optical module 200 can be pulled out of the cage 106.

[0070] The circuit board 300 includes circuit traces, electronic components and chips, etc. The electronic components and chips are connected according to the circuit design through the circuit traces to realize the functions of power supply, electrical signal transmission and grounding. The electronic components may include capacitors, resistors, transistors, metal-oxide-semiconductor field-effect transistors (Metal-Oxide-Semiconductor Field-Effect Transistor, MOSFET), etc. The chips may include microcontroller units (Microcontroller Unit, MCU), laser driver chips, transimpedance amplifiers (Transimpedance Amplifier, TIA), limiting amplifiers (Limiting amplifier), clock and data recovery chips (Clock and Data Recovery, CDR), power management chips, digital signal processing (Digital Signal Processing, DSP) chips.

[0071] The circuit board 300 is generally a rigid circuit board. Due to its relatively hard material, the rigid circuit board can also realize the load-bearing function. For example, the rigid circuit board can stably carry the above-mentioned electronic components and chips; the rigid circuit board can also be inserted into the electrical connector in the cage 106 of the host computer 100.

[0072] The circuit board 300 also includes a gold finger formed on the end surface thereof, and the gold finger is composed of a plurality of independent pins. The circuit board 300 is inserted into the cage 106, and the gold finger is connected to the electrical connector in the cage 106. The gold finger can be provided on the surface of only one side of the circuit board 300 (for example, Figure 4 The upper surface shown in the figure) can also be set on the upper and lower surfaces of the circuit board 300 to provide a larger number of pins, so as to adapt to occasions where the number of pins is large. The gold finger is 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, data signal transmission, etc. Of course, flexible circuit boards are also used in some optical modules. Flexible circuit boards are generally used in conjunction with rigid circuit boards to supplement rigid circuit boards.

[0073] The optical transceiver component 900 has both transmitting and receiving functions to realize a group of light transmission and a group of light reception.

[0074] As the communication rate increases, although the power consumption per unit bandwidth is decreasing, the overall power consumption of the optical module is still increasing. The heat dissipation method used in client devices is mostly air cooling, and its heat dissipation capacity has reached its limit for high-speed transmission systems. In order to get rid of the dilemma of air cooling, people began to study various liquid cooling methods, one of which is to immerse the switch in a refrigerant such as fluorinated liquid (FC-40).

[0075] When the optical module is immersed in the coolant, the coolant will penetrate into the inside of the optical cable. Due to the capillary absorption phenomenon, the coolant will flow along the inside of the optical cable to the other end of the optical cable, causing the coolant to contaminate the optical end face at the other end of the optical cable.

[0076] In some embodiments, the optical module 200 is detachably connected to the optical fiber 101 , that is, the optical module 200 has a pluggable optical port, and the optical fiber 101 is connected or disconnected with the optical module 200 by inserting or removing the pluggable optical port.

[0077] Figure 5 The figure is an assembly diagram of an optical module and an optical cable according to some embodiments. Figure 6 FIG. 1 is an exploded view of an optical module and an optical cable according to some embodiments. Figure 5 and Figure 6 As shown, in some embodiments, the optical module 200 is fixedly connected to the optical fiber 101, and the optical fiber is an active optical fiber or a pigtail.

[0078] A plurality of optical fibers are combined to form an optical cable 108, and the optical module 200 is fixedly connected to the optical cable 108, that is, the optical module 200 carries an optical cable 108. The optical cable 108 is an active optical cable (AOC optical cable) or a pigtail optical cable (Pigtail optical cable).

[0079] Figure 7 is an exploded view of an optical cable provided according to some embodiments. Figure 8 FIG. 1 is an exploded view of an optical cable fixture and an optical cable body according to some embodiments. Figure 7 and Figure 8 As shown, in some embodiments, the optical cable 108 can include an optical cable body 182. The optical cable body 182 can extend from inside the optical module 200 to outside the optical module 200.

[0080] In some embodiments, the optical cable 108 may include an optical cable fixture 181. The optical cable fixture 181 may be located at the connection between the optical cable 108 and the optical module 200. The optical cable fixture 181 may be coated on one end of the outer side of the optical cable body 182 to prevent the coolant from penetrating into the interior of the optical cable body 182. The optical cable fixture 181 may be engaged with the optical module 200 to securely connect the optical cable fixture 181 to the optical module 200.

[0081] In some embodiments, the optical cable 108 may include an isolator 183. The isolator 183 may be located in the middle of the optical cable 108. The isolator 183 may be coated on the middle of the outer side of the optical cable body 182 to isolate the cooling liquid from one end of the optical cable 108, thereby preventing the cooling liquid from penetrating from one end of the optical cable body 182 to the other end of the optical cable body 182. The middle of the outer side of the optical cable body 182 is only used to indicate the two ends that are not outside the optical cable body 182, but does not indicate the middle of the outer side of the optical cable body 182, that is, the middle of the outer side of the optical cable body 182 is not the middle point of the outer side of the optical cable body 182.

[0082] The optical cable fixing part 181 can be covered on one end of the outer side of the optical cable body 182 to prevent the cooling liquid from penetrating from the optical module 200 into the interior of the optical cable body 182 outside the optical module 200; the optical cable fixing part 181 can be engaged on the optical module 200 to prevent the cooling liquid penetrating into one end of the optical cable body 182 from penetrating into the other end of the optical cable body 182.

[0083] Fig. 9 The present invention is an exploded view of an optical cable fixture provided according to some embodiments. Fig.10 sectional views of a first crimping ring, a second crimping ring, and a clamp according to some embodiments. Fig.11 1 is a cross-sectional view of an optical cable body and an optical cable fixing member provided according to some embodiments. Fig. 9 , Fig.10 and Fig.11 As shown, the optical cable body 182 within the optical module 200 includes only optical fibers.

[0084] like Fig. 9 , Fig.10 and Fig.11 As shown, the optical cable body 182 located outside the optical module 200 may include a cable sheath 1821 .

[0085] In some embodiments, an optical fiber 1822 (ie, optical fiber 101 ) may be disposed in the cable sheath 1821 . The optical fiber 1822 may extend from inside the optical module 200 to outside the optical module 200 , that is, the optical fiber 1822 includes an optical fiber inside the optical module 200 and an optical fiber outside the optical module 200 .

[0086] In some embodiments, a reinforcing wire 1823 may be provided in the cable sheath 1821. The reinforcing wire 1823 is Kevlar, which has good flexibility. The reinforcing wire 1823 may be located around the optical fiber 1822 to form a protective film around the optical fiber 1822, thereby protecting the optical fiber 1822.

[0087] like Fig. 9 , Fig.10 and Fig.11As shown, in some embodiments, the optical cable fixing member 181 includes a clamp 1811. One end of the clamp 1811 can be clamped at the optical port of the optical module 200. The other end of the clamp 1811 can be arranged adjacent to the cable skin 1821. The inner side of the clamp 1811 can have a first cavity. An optical fiber 1822 can be arranged in the first cavity. Sealing glue can be arranged in the first cavity. After the sealing glue is cured, a first sealing member is formed. The first sealing member can be filled in the gap between the inner side wall of the clamp 1811 and the optical fiber 1822, so that the first sealing member and the optical fiber 1822 are connected seamlessly, thereby preventing the cooling liquid inside the optical module 200 from penetrating into the interior of the optical cable body 182 through the first cavity of the clamp 1811.

[0088] In some embodiments, the sealing glue is a soft glue, so that the first sealing component has not only a sealing function, but also a function of protecting the optical cable. For example, the sealing glue is a silicone.

[0089] In some embodiments, the clamp 1811 may include a clamp body 1815. The clamp body 1815 may be located at a second end of the clamp 1811, that is, an end of the clamp 1811 away from the optical module 200.

[0090] In some embodiments, the clamp 1811 may include a stop protrusion 1816. The stop protrusion 1816 may be located at a first end of the clamp 1811, that is, an end of the clamp 1811 close to the optical module 200. The inner side wall of the clamp body 1815 and the inner side wall of the stop protrusion 1816 may enclose a first cavity.

[0091] like Fig. 9 , Fig.10 and Fig.11 As shown, in some embodiments, the optical cable fixing member 181 may include a first crimping ring 1813. The first end of the first crimping ring 1813 is crimped to the second end of the clamp 1811, and a reinforcement wire 1823 is provided between the first crimping ring 1813 and the clamp, so that one end of the first crimping ring 1813 can be crimped to the reinforcement wire 1823 outside the clamp 1811. The other end of the first crimping ring 1813 can be crimped to the cable sheath 1821 to connect the optical cable fixing member 181 with the optical cable body 182.

[0092] In some embodiments, the end of the reinforcing wire 1823 (Kevlar) passes over the first crimping ring 1813 to ensure that the tension of the optical cable body 182 meets the requirements.

[0093] However, the end of the reinforcing wire 1823 (Kevlar) passes over the first crimping ring 1813 , and the cooling liquid will penetrate into the interior of the optical cable body 182 along the reinforcing wire 1823 (Kevlar).

[0094] In order to solve the technical problem that the coolant penetrates into the interior of the optical cable body 182 along the reinforcing wire 1823 (Kevlar), as Fig. 9 , Fig.10 and Fig.11 As shown, in some embodiments, the optical cable fixing member 181 may include a second crimping ring 1812. The second crimping ring 1812 may be covered on the outside of the clamp body 1815. The second crimping ring 1812 may be located in front of the stop protrusion 1816. A reinforcement wire 1823 may be provided between the second crimping ring 1812 and the outside of the clamp 1811 to crimp the reinforcement wire 1823 on the outside of the clamp body 1815. The reinforcement wire 1823 may not go beyond the left end of the second crimping ring 1812 to reduce the infiltration of the cooling liquid into the interior of the optical cable body 182 through the reinforcement wire 1823.

[0095] One end of the first crimping ring 1813 can be crimped to the right end of the outer side of the second crimping ring 1812, the middle of the first crimping ring 1813 can be crimped to the reinforcement line 1823 on the outer side of the clamp body 1815, and the other end of the first crimping ring 1813 can be crimped to the cable skin 1821 to compress the optical cable fixing 181 and the reinforcement line 1823, thereby ensuring that the tension of the optical cable 108 meets the requirements.

[0096] In some embodiments, the height of the second sealing member shall not exceed the height of the first crimping ring 1813 to prevent the protective sleeve 1814 from being pushed to the fixed position of the clamp 1811, that is, the protective sleeve 1814 is fixed before the stop protrusion 1816 of the clamp 1811.

[0097] After the first crimping ring 1813 is crimped, it is necessary to observe whether the first crimping ring 1813 is flat and has any damaged threads.

[0098] The second crimping ring 1812 is clearly visible. After observing that the first crimping ring 1813 is flat, has no damaged threads, and the second crimping ring 1812 is clearly visible, a tensile test is performed to ensure that the tensile force of the optical cable reaches 15Kg / min.

[0099] After completing the tensile test, apply sealing glue on the outside of the second crimping ring 1812, and apply sealing glue on the connection between the first crimping ring 1813 and the optical cable body 182. After the sealing glue is stationary for a period of time, the sealing glue on the outside of the second crimping ring 1812 solidifies to form a seal to isolate the second crimping ring 1812 from the coolant, thereby preventing the coolant from penetrating into the optical fiber 1822 inside the optical cable body 182 through the reinforcement line 1823. The sealing glue at the connection between the first crimping ring 1813 and the optical cable body 182 solidifies to form a seal to block the gap between the optical cable body 182 and the first crimping ring 1813, so as to ensure that the first crimping ring 1813 and the optical cable body 182 are sealed and connected.

[0100] like Fig. 9 , Fig.10 and Fig.11 As shown, in some embodiments, the optical cable fixing member 181 may include a protective cover 1814. The protective cover 1814 may be disposed on the second sealing member, the first crimping ring 1813 and the cable sheath 1821 to protect the optical cable body 182.

[0101] In order to solve the technical problem that the coolant penetrates into the interior of the optical cable body 182 along the reinforcement line 1823 (Kevlar), the present application proposes another optical cable fixing part.

[0102] Fig.12 An exploded view of another optical cable fixture provided according to some embodiments. Fig.13 sectional views of a first crimping ring, another clamp, and an optical cable body according to some embodiments. Fig.14 1 is a cross-sectional view of an optical cable and another optical cable fixing member provided according to some embodiments. Fig.12 , Fig.13 and Fig.14 As shown, in some embodiments, the optical cable fixing member 181 may include a clamp 1811. One end of the clamp 1811 may be clamped at the optical port of the optical module 200. The other end of the clamp 1811 may be arranged adjacent to the cable skin 1821. The inner side of the clamp 1811 may have a first cavity. An optical fiber 1822 may be arranged in the first cavity. Sealing glue may be arranged in the first cavity. After the sealing glue is cured, a first sealing member is formed. The first sealing member may be filled in the gap between the inner side wall of the clamp 1811 and the optical fiber 1822, so that the first sealing member and the optical fiber 1822 are connected seamlessly, thereby preventing the cooling liquid inside the optical module 200 from penetrating into the interior of the optical cable body 182 through the first cavity of the clamp 1811.

[0103] In some embodiments, the clamp 1811 may include a fixing protrusion 1818. The fixing protrusion 1818 may be located at a first end of the clamp 1811, that is, an end of the clamp 1811 close to the optical module 200. The fixing protrusion 1818 may be engaged with the optical port of the optical module 200.

[0104] In some embodiments, the clamp 1811 may include a clamp body 1815. The clamp body 1815 may be located at a second end of the clamp 1811, that is, an end of the clamp 1811 away from the optical module 200.

[0105] In some embodiments, the clamp 1811 may include a stop protrusion 1816. The stop protrusion 1816 may be located between the fixing protrusion 1818 and the clamp body 1815. One end of the stop protrusion 1816 may be connected to the fixing protrusion 1818. The inner wall of the fixing protrusion 1818, the inner wall of the stop protrusion 1816 and the inner wall of the clamp body 1815 form a first cavity.

[0106] like Fig.12 , Fig.13 and Fig.14 As shown, in some embodiments, the optical cable fixture 181 may include a first crimping ring 1813. One end of the first crimping ring 1813 may be crimped to the reinforcement wire 1823 outside the clamp 1811. The other end of the first crimping ring 1813 may be crimped to the cable sheath 1821 to compress the optical cable fixture 181 and the reinforcement wire 1823.

[0107] In some embodiments, the end of the reinforcing wire 1823 (Kevlar) passes over the first crimping ring 1813 to ensure that the tension of the optical cable body 182 meets the requirements.

[0108] However, the end of the reinforcing wire 1823 (Kevlar) passes over the first crimping ring 1813, and the coolant will penetrate into the interior of the optical cable body 182 along the reinforcing wire 1823 (Kevlar). In order to solve the technical problem that the coolant penetrates into the interior of the optical cable body 182 along the reinforcing wire 1823 (Kevlar), in some embodiments, the space between the stop protrusion 1816 and the first crimping ring 1813 can be filled with sealing glue. Since the reinforcing wire 1823 that passes over the first crimping ring 1813 can be located between the stop protrusion 1816 and the first crimping ring 1813, when the sealing glue is cured to form a second sealing member, the reinforcing wire 1823 does not pass out of the second sealing member, so that the reinforcing wire is inside the second sealing member, thereby reducing the coolant from penetrating into the interior of the optical cable body 182 along the reinforcing wire 1823.

[0109] However, due to the large distance between the stop protrusion 1816 and the first crimping ring 1813, the sealing glue between the stop protrusion 1816 and the first crimping ring 1813 will overflow everywhere. In addition, due to the connection between the stop protrusion 1816 and the fixing protrusion 1818, the sealing glue between the stop protrusion 1816 and the first crimping ring 1813 may overflow to the fixing protrusion 1818, affecting the assembly of the optical cable fixing member and the optical module. In order to avoid these problems, in some embodiments, the outer wall of the clamp 1811 may be provided with a limiting protrusion 1817, and the limiting protrusion 1817 may be located between the stop protrusion 1816 and the first crimping ring 1813, that is, the limiting protrusion 1817 is provided at the rear side of the stop protrusion 1816. The space between the limiting protrusion 1817 and the first crimping ring 1813 may be filled with sealing glue to reduce the sealing glue from overflowing to the fixing protrusion 1818.

[0110] The limiting protrusion 1817, the outer side of the clamp body 1815 and the first crimping ring 1813 form a U-shaped storage groove 185. The reinforcement wire 1823 that passes over the first crimping ring 1813 is located in the storage groove 185. The storage groove 185 can be filled with sealing glue, and when the sealing glue is cured to form the second sealing member 186, the reinforcement wire 1823 does not pass through the second sealing member 186, so that the reinforcement wire 1823 is in the second sealing member 186, thereby reducing the cooling liquid from penetrating into the interior of the optical cable body 182 along with the reinforcement wire 1823.

[0111] In some embodiments, the limiting protrusion 1817 may be located between the stop protrusion 1816 and the clamp body 1815 , that is, the limiting protrusion 1817 is closer to the cable skin 1821 than the stop protrusion 1816 , so that the limiting protrusion 1817 is located between the stop protrusion 1816 and the first crimping ring 1813 .

[0112] Apply sealant glue at the connection between the first crimping ring 1813 and the optical cable body 182. After the sealant glue is stationary for a period of time, the sealant glue at the connection between the first crimping ring 1813 and the optical cable body 182 solidifies to form a seal to block the gap between the optical cable body 182 and the first crimping ring 1813, so as to ensure that the first crimping ring 1813 and the optical cable body 182 are sealed and connected.

[0113] In some embodiments, the height of the limiting protrusion 1817 may be higher than the height of the clamp body 1815 , so that the first crimping ring 1813 crimped onto the clamp body 1815 may form a storage groove with the limiting protrusion 1817 .

[0114] like Fig.12 , Fig.13 and Fig.14 As shown, in some embodiments, the optical cable fixing member 181 may include a protective cover 1814. The protective cover 1814 may be disposed on the cable skin 1821 to protect the optical cable body 182. The protective cover 1814 may be disposed on the first crimping ring 1813 to protect the first crimping ring 1813. The protective cover 1814 may be disposed on the second sealing member to protect the second sealing member. The protective cover 1814 may be disposed on the limiting protrusion 1817 to protect the limiting protrusion 1817. The protective cover 1814 may be disposed in the gap between the limiting protrusion 1817 and the stop protrusion 1816.

[0115] The protective cover 1814 moves toward the optical module 200 , so that the protective cover 1814 is successively covered on the cable skin 1821 , the first crimping ring 1813 , the second sealing member and the limiting protrusion 1817 .

[0116] In some embodiments, the height of the fixing protrusion 1818 may be greater than the height of the stopping protrusion 1816 , so that the protective cover 1814 stops before the fixing protrusion 1818 .

[0117] In some embodiments, the height of the limiting protrusion 1817 may be higher than the height of the first crimping ring 1813 to prevent the protective sleeve 1814 from being pushed only to the first crimping ring 1813 and unable to continue to move toward the limiting protrusion 1817 .

[0118] In some embodiments, the height of the second sealing member in the storage groove 185 may be no greater than the height of the first crimping ring 1813 to prevent the protective sleeve 1814 from being pushed only to the first crimping ring 1813 and unable to continue to move toward the second sealing member.

[0119] In some embodiments, the height of the limiting protrusion 1817 can be higher than the height of the second sealing member in the storage groove 185 to prevent the protective cover 1814 from being pushed only to the second sealing member and being unable to continue to move toward the limiting protrusion 1817 .

[0120] In some embodiments, there is a gap between the limiting protrusion 1817 and the stopping protrusion 1816 to match other structural components, thereby facilitating the assembly of the optical cable fixing component 181 and the optical module.

[0121] In some embodiments, the cable sheath 1821 of the optical cable body 182 outside the optical module 200 may be disconnected.

[0122] In some embodiments, the optical fibers 1822 of the optical cable body 182 outside the optical module 200 are not disconnected.

[0123] In some embodiments, the reinforcing wire 1823 of the optical cable body 182 outside the optical module 200 may be disconnected.

[0124] In some embodiments, the optical cable body 182 outside the optical module 200 may be a first optical cable body. The first optical cable body may include an unbroken cable sheath 1821 , an unbroken optical fiber 1822 , and an unbroken reinforcing wire 1823 .

[0125] For the first optical cable body, a sealant may be applied to the inner wall of the cable skin 1821, the optical fiber 1822 and the reinforcing wire 1823, and the sealant is cured to form a sealant, which is coated on the inner wall of the cable skin 1821, the optical fiber 1822 and the reinforcing wire 1823 to prevent the coolant from penetrating from one end of the optical cable body 182 to the other end of the optical cable body 182. That is, when the optical cable body 182 located outside the optical module 200 is the first optical cable body, there is no need to set an isolator in the middle of the optical cable body 182.

[0126] In some embodiments, the optical cable body 182 outside the optical module 200 may be a second optical cable body. The second optical cable body may include a disconnected cable sheath 1821 , an undisconnected optical fiber 1822 , and an undisconnected reinforcing wire 1823 .

[0127] For the second optical cable body, a sealant can be applied on the inner wall of the unbroken cable skin 1821, the unbroken optical fiber 1822 and the unbroken reinforcing wire, and the sealant is cured to form a sealant, which is coated on the inner wall of the cable skin 1821, the optical fiber 1822 and the reinforcing wire 1823 to prevent the coolant from penetrating from one end of the optical cable body 182 to the other end of the optical cable body 182. That is, when the optical cable body 182 located outside the optical module 200 is the third optical cable body, an isolator needs to be provided in the middle of the optical cable body 182 to prevent the coolant from penetrating from one end of the optical cable body 182 to the other end of the optical cable body 182.

[0128] In some embodiments, the optical cable body 182 outside the optical module 200 may be a third optical cable body. The third optical cable body may include a disconnected cable sheath 1821 , an undisconnected optical fiber 1822 , and a disconnected reinforcing wire 1823 .

[0129] For the third optical cable body, sealant can be applied to the inner wall of the disconnected cable sheath 1821, the outer wall of the disconnected cable sheath 1821, the cross section of the disconnected cable sheath 1821, the outer wall of the undisconnected reinforcing wire 1823 and the outer wall of the undisconnected optical fiber 1822, and the sealant is cured to form a sealant, which is coated on the inner wall of the cable sheath 1821, the outer wall of the disconnected cable sheath 1821, the cross section of the disconnected cable sheath 1821, the outer wall of the undisconnected reinforcing wire 1823 and the outer wall of the undisconnected optical fiber 1822 to prevent the cooling liquid from penetrating from one end of the optical cable body 182 to the other end of the optical cable body 182. That is, when the optical cable body 182 located outside the optical module 200 is the second optical cable body, an isolation piece needs to be provided in the middle of the optical cable body 182 to prevent the cooling liquid from penetrating from one end of the optical cable body 182 to the other end of the optical cable body 182.

[0130] Fig.15 The present invention is an exploded view of an optical cable body and a spacer according to some embodiments. Fig.16 1 is a cross-sectional view of an optical cable body and a spacer according to some embodiments. Fig.15 and Fig.16 As shown, in some embodiments, the isolating member 183 may include an isolating sleeve 1831. A second cavity may be provided in the isolating sleeve 1831. An optical cable body may be provided in the second cavity. A sealing member may be provided in the second cavity. The sealing member may be filled in the gap between the optical cable body and the isolating sleeve 1831 to prevent the cooling liquid from penetrating from one end of the optical cable body 182 to the other end of the optical cable body 182.

[0131] The optical cable body in the second cavity can be the second optical cable body or the third optical cable body. When the optical cable body 182 is the third optical cable body, the reinforcing wire in the second cavity is broken. In some embodiments, the length of the broken reinforcing wire in the second cavity is 3 to 5 mm to ensure that the tension of the isolation member 183 meets the requirements.

[0132] In some embodiments, isolation sleeve 1831 may include a first isolation portion.

[0133] In some embodiments, the isolation sleeve 1831 may include a second isolation portion. The first isolation portion and the second isolation portion may have the same semicircular ring shape.

[0134] The first isolating part and the second isolating part are connected to form an isolating sleeve 1831 with a second cavity. Apply sealing glue on the bottom of the first isolating part, install the cut optical cable body inside the first isolating part, and then apply a layer of sealing glue to completely block the cut ends of the cut optical cable body; cover the second isolating part, and fix the first isolating part and the second isolating part with masking tape; place the fixed first isolating part and the second isolating part at a high temperature of 100°C to dry for more than 1 hour, and wait for the sealing glue to solidify to form a seal.

[0135] In some embodiments, the isolating member 183 may include a first protective sleeve 1832. The first protective sleeve 1832 may be disposed on the isolating sleeve 1831 to ensure the strength of the isolating sleeve 1831 and to prevent the isolating sleeve 1831 from breaking at the connection between the first isolating portion and the second isolating portion.

[0136] In some embodiments, a third cavity may be provided inside the first protective sleeve 1832. An isolation sleeve 1831 may be provided in the third cavity. A fourth sealing member may be provided in the third cavity. The fourth sealing member may be located between the isolation sleeve 1831 and the first protective sleeve 1832 and at both ends of the first protective sleeve 1832 to fill the gap between the optical cable body 182, the isolation sleeve 1831 and the first protective sleeve 1832, thereby achieving a stable connection between the isolation sleeve 1831 and the first protective sleeve 1832, and a sealed connection between the first protective sleeve 1832 and the optical cable body 182.

[0137] In some embodiments, the isolation member 183 may include a protective tail pipe 1833. The protective tail pipe 1833 may be covered at one end of the isolation sleeve 1831. The protective tail pipe 1833 is correspondingly provided with a limiting protrusion 1835 to limit the clamping position of the protective tail pipe 1833 on the first protective sleeve 1832.

[0138] In some embodiments, the isolation member 183 may include a protective tail pipe 1834. The protective tail pipe 1834 may be covered at the other end of the isolation sleeve 1831. The protective tail pipe 1834 is correspondingly disposed with another limiting protrusion 1835 to limit the clamping position of the protective tail pipe 1834 in the first protection sleeve 1832.

[0139] The protective tail tube 1833 and the protective tail tube 1834 are respectively covered at the two ends of the isolation sleeve 1831 to protect the optical cable body. After the sealing glue in the isolation sleeve 1831 is cured to form a sealing member, the protective tail tubes 1833 are respectively put on the two ends of the isolation sleeve 1831.

[0140] In some embodiments, the protective tail pipe may include a clamping end, one end of which may be covered on one end of the isolation sleeve 1831 .

[0141] In some embodiments, the protective tail tube may include a protective end. One end of the protective end may be connected to the other end of the clamping end. The other end of the protective end may wrap the optical cable body 182. The two ends of the protective end are not parallel so that the protective end has a certain tilt angle.

[0142] In some embodiments, the inclination angle of the protection end is not equal to 90°, so as to reduce the stress received by the optical cable body 182 and protect the optical cable body 182 .

[0143] Fig.17 An exploded view of an isolation member provided according to some embodiments. Fig.18 is a cross-sectional view of an isolation element provided according to some embodiments. Fig.19 FIG. 1 is a cross-sectional view of a first protective sleeve and a protective tail pipe provided according to some embodiments. Fig.17 , Fig.18 and Fig.19 As shown, in some embodiments, the isolation sleeve 1831 may be provided with a first through hole 1837. The optical cable body 182 may pass through the first through hole 1837 and enter the isolation member 183 from the outside.

[0144] In some embodiments, a second through hole 1838 may be provided at one end of the first protective sleeve 1832. The second through hole 1838 may be provided corresponding to the first through hole 1837 to avoid the optical cable body 1822, so that the optical cable body 182 passes through the first through hole 1837 and the second through hole 1838.

[0145] In some embodiments, the protective tail tube 1833 may be provided with a third through hole 1839. The third through hole 1839 may be provided corresponding to the first through hole 1837 and the second through hole 1838 to avoid the optical cable body 182 so that the optical cable body 182 passes through the first through hole 1837, the second through hole 1838 and the third through hole 1839.

[0146] In some embodiments, a limiting protrusion 1835 may be provided on the outer side of the first protective sleeve 1832. Two limiting protrusions 1835 are respectively located at two ends of the first protective sleeve 1832.

[0147] In some embodiments, a limiting step 1836 may be provided in the third cavity. The limiting step 1836 is used to limit the position of the isolation sleeve 1831 in the first protective sleeve 1832. By way of example, a limiting step 1836 is provided at one end of the third cavity inside the first protective sleeve 1832, and the isolation sleeve 1831 is located between the other end of the third cavity and the limiting step 1836 to limit the position of the isolation sleeve 1831 in the first protective sleeve 1832. By way of example, a limiting step 1836 is provided at each end of the third cavity inside the first protective sleeve 1832, and the isolation sleeve 1831 is located between the two limiting steps 1836 to limit the position of the isolation sleeve 1831 in the first protective sleeve 1832.

[0148] In some embodiments, a seal is provided in all areas of the third cavity except the isolation sleeve 1831. The seal is located between the limiting step 1836 and the inner wall of the first protective sleeve 1832. It is not only used to achieve a fixed connection between the isolation sleeve 1831 and the first protective sleeve 1832, but also used to achieve a sealed connection between the first protective sleeve 1832 and the optical cable body 182 to further prevent the infiltration of cooling liquid.

[0149] After the sealing glue in the isolation sleeve 1831 solidifies into a seal, the outside of the isolation sleeve 1831 is coated with sealing glue and inserted into the first protective sleeve 1832. After sealing glue is applied to both ends of the first protective sleeve 1832 and sealed, the sleeve is placed at a high temperature of 100°C to dry for more than 1 hour, waiting for the sealing glue to solidify to form a seal. After the sealing glue in the first protective sleeve 1832 solidifies into a seal, sealing glue is applied to both ends of the first protective sleeve 1832 and the protective tail pipe 1833 is put on.

Fig.21 FIG. 4 is an exploded view of another isolating member provided according to some embodiments. Fig. 22 FIG. 2 is a cross-sectional view of another isolating member and an optical cable body according to some embodiments. Fig. 20 , Fig.21 and Fig. 22As shown, in some embodiments, the isolating member 183 may include an isolating sleeve 1831. A second cavity may be provided in the isolating sleeve 1831. An optical cable body may be provided in the second cavity. A sealing member may be provided in the second cavity. The sealing member may be filled in the gap between the optical cable body and the isolating sleeve 1831 to prevent the cooling liquid from penetrating from one end of the optical cable body 182 to the other end of the optical cable body 182.

[0151] In some embodiments, the isolation sleeve 1831 may be provided with a first through hole 1837. The optical cable body 182 may pass through the first through hole 1837 and enter the isolation member 183 from the outside.

[0152] The optical cable body in the second cavity can be the second optical cable body or the third optical cable body. When the optical cable body 182 is the third optical cable body, the reinforcing wire in the second cavity is broken. In some embodiments, the length of the broken reinforcing wire in the second cavity is 3 to 5 mm to ensure that the tension of the isolation member 183 meets the requirements.

[0153] In some embodiments, isolation sleeve 1831 may include a first isolation portion.

[0154] In some embodiments, the isolation sleeve 1831 may include a second isolation portion. The first isolation portion and the second isolation portion may have the same shape.

[0155] The first isolating part and the second isolating part are connected to form an isolating sleeve 1831 with a second cavity. Apply sealing glue on the bottom of the first isolating part, install the cut optical cable body inside the first isolating part, and then apply a layer of sealing glue to completely block the cut ends of the cut optical cable body; cover the second isolating part, and fix the first isolating part and the second isolating part with masking tape; place the fixed first isolating part and the second isolating part at a high temperature of 100°C to dry for more than 1 hour, and wait for the sealing glue to solidify to form a seal.

[0156] like Fig. 20 , Fig.21 and Fig. 22 As shown, in some embodiments, the isolation member 183 may include a first protective sleeve 1832. The first protective sleeve 1832 may be covered on the isolation sleeve 1831 to ensure the strength of the isolation sleeve 1831 and to avoid the isolation sleeve 1831 from breaking at the connection between the first isolation part and the second isolation part.

[0157] In some embodiments, the material of the first protective sleeve 1832 can be metal or plastic with greater hardness, so that the first protective sleeve 1832 is a hard protective sleeve, so as to better prevent the isolation sleeve 1831 from breaking at the connection between the first isolation part and the second isolation part, thereby better protecting the isolation sleeve 1831.

[0158] In some embodiments, a second through hole 1838 may be provided at one end of the first protective sleeve 1832. The second through hole 1838 may be provided corresponding to the first through hole 1837 to avoid the optical cable body 1822, so that the optical cable body 182 passes through the first through hole 1837 and the second through hole 1838.

[0159] In some embodiments, a third cavity may be provided inside the first protective sleeve 1832. An isolation sleeve 1831 may be provided in the third cavity. A fourth sealing member may be provided in the third cavity. The fourth sealing member may be located between the isolation sleeve 1831 and the first protective sleeve 1832 and at both ends of the first protective sleeve 1832 to fill the gap between the optical cable body 182, the isolation sleeve 1831 and the first protective sleeve 1832, thereby achieving a fixed connection between the isolation sleeve 1831 and the first protective sleeve 1832, and a sealed connection between the first protective sleeve 1832 and the optical cable body 182, thereby preventing the infiltration of the cooling liquid.

[0160] In some embodiments, a limiting step may be provided in the third cavity inside the first protective sleeve 1832. The limiting step is used to limit the position of the isolation sleeve 1831 inside the first protective sleeve 1832. By way of example, a limiting step is provided at one end of the third cavity inside the first protective sleeve 1832, and the isolation sleeve 1831 is located between the other end of the third cavity and the limiting step to limit the position of the isolation sleeve 1831 in the first protective sleeve 1832. By way of example, a limiting step is provided at each end of the third cavity inside the first protective sleeve 1832, and the isolation sleeve 1831 is located between the two limiting steps to limit the position of the isolation sleeve 1831 in the first protective sleeve 1832.

[0161] like Fig. 20 , Fig.21 and Fig. 22 As shown, in some embodiments, the isolating member 183 may include a second protective sleeve 184. The second protective sleeve 184 may be disposed on the first protective sleeve 1832 and the optical cable body 182 located outside the first protective sleeve 1832 to protect the optical cable body 182.

[0162] In some embodiments, the material of the second protective sleeve 184 is plastic with relatively low hardness, so that the second protective sleeve 184 is a soft protective sleeve.

[0163] The second protective sleeve 184 has heat shrinkability, that is, the second protective sleeve 184 will shrink after being heated. For example, the second protective sleeve 184 is a heat shrink tube.

[0164] After the second protective sleeve 184 is sleeved on the first protective sleeve 1832 and the optical cable body 182, the connection between the first protective sleeve 1832 and the optical cable body 182 outside the first protective sleeve 1832 is heated. After heating, the size of the area covered by the first protective sleeve 1832 is larger than the size of the area covered by the optical cable body 182, so that the second protective sleeve 184 can be tightly connected with the first protective sleeve 1832 and the optical cable body 182 outside the first protective sleeve 1832, thereby improving the connection stability between the isolation piece 183 and the optical cable body 182.

[0165] In some embodiments, the size of the area covered by the first protective sleeve 1832 can be greater than or equal to the size of the first protective sleeve 1832, so that the second protective sleeve 184 can accommodate the first protective sleeve 1832, thereby making the second protective sleeve 184 tightly connected to the first protective sleeve 1832.

[0166] In some embodiments, the size of the area covered on the optical cable body 182 can be greater than or equal to the size of the optical cable body 182 located outside the first protective sleeve 1832, so that the second protective sleeve 184 can accommodate the optical cable body 182 located outside the first protective sleeve 1832, thereby making the second protective sleeve 184 tightly connected to the optical cable body 182 located outside the first protective sleeve 1832.

[0167] After the sealing glue in the isolation sleeve 1831 solidifies into a seal, the outside of the isolation sleeve 1831 is coated with sealing glue and inserted into the first protective sleeve 1832. After sealing glue is applied to both ends of the first protective sleeve 1832 and sealed, it is placed at a high temperature of 100°C to dry for more than 1 hour, waiting for the sealing glue to solidify to form a seal. After the sealing glue in the first protective sleeve 1832 solidifies into a seal, the outside of the first protective sleeve 1832 is coated with sealing glue and inserted into the second protective sleeve 184.

The first protective sleeve 1832 may be placed in the fourth cavity 1841, so that the second protective sleeve 184 may be covered on the first protective sleeve 1832, thereby protecting the optical cable body.

[0169] In some embodiments, the second protective sleeve 184 may include a second region. The second region may be connected to the first region. The inner cavity of the second region may be a fourth through hole 1842. The optical cable body 182 may be disposed in the fourth through hole 1842. The fourth through hole 1842 may be disposed corresponding to the first through hole 1837 and the second through hole 1838 to avoid the optical cable body 182, so that the optical cable body 182 passes through the first through hole 1837 and the fourth through hole 1842.

[0170] The first region may be located between two second regions. One end of the first region may be connected to one second region, and the other end of the first region may be connected to another second region. The radius of the second region is smaller than the radius of the first region.

[0171] In some embodiments, the connection between the first region and the second region may be arranged obliquely with respect to the first region.

[0172] In some embodiments, the connection between the first region and the second region may be arranged obliquely with respect to the second region.

[0173] The connection between the first area and the second area is inclined with respect to the first area and the second area, so as to reduce the stress received by the optical cable body 182 and protect the optical cable body 182 .

[0174] The connection between the first region and the second region has an inclination angle with the first region that is not equal to 90°. The connection between the first region and the second region has an inclination angle with the second region that is not equal to 90°.

The area between the limiting protrusion and the first crimping ring is a storage groove, and a second sealing member is also arranged in the storage groove.

The isolation member includes an isolation sleeve, a first protective sleeve and a second protective sleeve. The isolation sleeve has a second cavity inside, and the optical cable body and a third sealing member are arranged in the second cavity.
