Description

Technical Field

[0001] The present application relates to the field of optical fiber communication technology, and more particularly to a signal transmission wire that can be mass-produced to reduce manufacturing costs and can prevent heat dissipation liquid from penetrating and affecting signal transmission. Background Art

[0002] With the rapid development of network technology, fiber-optic communication has gradually replaced conventional electrical communication technologies for signal transmission due to its numerous advantages, including high data transmission speeds, long transmission distances, resistance to electromagnetic interference, and high security. Consequently, fiber-optic communication has become a major modern communication technology, widely used for information communication between various fiber-optic network devices.

[0003] Fiber optic network equipment in the fiber optic communications industry often utilizes signal transmission cables. Generally speaking, these cables include photoelectric converters, which in turn include photoelectric conversion modules and photoelectric converter cables. The photoelectric conversion modules convert electrical signals into optical signals, or vice versa. The photoelectric converter cables connect the photoelectric conversion modules to the fiber optic network equipment, transmitting optical signals between them. However, the length of the photoelectric converter cables depends on the distance between the photoelectric conversion modules and the fiber optic network equipment. Specifically, the length of the photoelectric converter cables depends on the transmission distance of the optical signal. This distance varies depending on the application or usage scenario, requiring customization of the photoelectric converter cable length. This prevents mass production of photoelectric converters and hinders effective manufacturing cost reduction.

[0004] Furthermore, since fiber optic network equipment typically operates continuously for long periods of time, the operating temperature of the equipment tends to rise, necessitating heat dissipation. To dissipate heat, the equipment is typically immersed in a high-thermal-conductivity heat dissipation liquid, allowing the equipment to operate in a liquid heat dissipation environment. This allows the heat generated by the operation of the equipment to be rapidly dissipated through the heat dissipation liquid, thereby improving the performance and lifespan of the equipment.

[0005] However, if the optical fiber network equipment is immersed in the heat dissipation liquid, the signal transmission cables connecting the optical fiber network equipment also need to be immersed in the heat dissipation liquid. Therefore, if the signal transmission cables have poor waterproof performance, the heat dissipation liquid can easily penetrate the signal transmission cables and affect signal transmission.

[0006] In view of this, how to improve existing signal transmission cables, which requires customized extension length of optical fiber cables for photoelectric converters, and how to enhance the waterproofness of signal transmission cables to prevent heat dissipation liquid from seeping into the signal transmission cables are urgent issues that need to be addressed by those skilled in the art.

[0100] The following describes the embodiments of the present application through specific examples. Those skilled in the art can easily understand the other advantages and effects of the present application from the content disclosed in this specification. The present application can also be implemented or applied through other different specific embodiments. The details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that the following embodiments and features in the embodiments can be combined with each other unless they conflict.

[0101] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application. Therefore, the illustrations only show components related to the present application and are not drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0102] The present application provides a signal transmission cable, which includes a photoelectric converter and an extension optical cable. The photoelectric converter includes a photoelectric converter cable. The photoelectric converter cable can transmit an optical signal, and the extension optical cable can be connected to the photoelectric converter cable to increase the transmission distance of the optical signal. This means that the length of the photoelectric converter cable does not need to be changed depending on the usage field or method. In this way, the photoelectric converter can be mass-produced, reducing manufacturing costs.

[0103] For the description of the embodiments disclosed in this application, please refer to Figures 1 to 12 .

[0104] At Figures 1 to 12In the illustrated embodiment, at least one signal transmission cable 1 is provided. The signal transmission cable 1 can be plugged into an optical fiber network device 2 to transmit signals. The signal transmission cable 1 includes: a main-side photoelectric converter 11, an extension optical cable 12, and a main-side optical cable connector 13.

[0105] It should be noted that in the above embodiment, the optical network device 2 can be immersed in a high-thermal-conductivity heat-dissipating liquid L, allowing the optical network device 2 to operate in a liquid heat-dissipating environment. Heat generated by the operation of the optical network device 2 can be quickly dissipated through the heat-dissipating liquid L, thereby improving the performance and lifespan of the optical network device 2. Accordingly, the signal transmission cable 1 can be immersed in the high-thermal-conductivity heat-dissipating liquid L along with the optical network device 2.

[0106] Regarding the master-side photoelectric converter 11, the master-side photoelectric converter 11 includes a master-side photoelectric conversion module 111 and a master-side photoelectric converter optical cable 112. The master-side photoelectric conversion module 111 can convert a master-side electrical signal into a master-side optical signal, or alternatively, the master-side photoelectric conversion module 111 can convert the master-side optical signal into the master-side electrical signal. The master-side photoelectric converter optical cable 112 can provide transmission for the master-side optical signal and includes a master-side photoelectric converter optical cable docking end E1121.

[0107] Regarding the extension optical cable 12, Figure 7 In the embodiment shown, one side of the extension optical cable 12 includes a main-side extension optical cable docking end E1211. In the above embodiment, the main-side extension optical cable docking end E1211 includes a structure that can provide docking for other optical cables.

[0108] Regarding the main side optical cable connector 13, Figure 7 In the illustrated embodiment, the main side optical cable connector 13 includes a main side optical cable connector carrier 131, a main side optical cable connector cover 132 and a main side optical cable connector adhesive 133. The main side optical cable connector carrier 131 includes a main side carrier docking space S131.

[0109] In the above embodiment, the main-side extension optical cable docking end E1211 can dock with the main-side optoelectronic converter cable docking end E1121 in the main-side carrier docking space S131, allowing the main-side optoelectronic converter cable 112 to transmit the main-side optical signal from the main-side extension optical cable docking end E1211 to the main-side extension optical cable docking end E1211 and into the extension optical cable 12. The extension optical cable 12 can be extended to increase the transmission distance of the main-side optical signal. It should be noted that the length of the extension optical cable 12 can be adjusted according to the distance between the main-side optoelectronic converter module 111 and the optical fiber network device. In other words, the length of the extension optical cable 12 can be adjusted according to the transmission distance of the main-side optical signal. This means that the length of the main-side optoelectronic converter cable 112 does not need to be changed depending on the usage scenario or method. Therefore, the main-side optoelectronic converter 11 can be mass-produced, reducing manufacturing costs.

[0110] Furthermore, the main-side optical cable connector adhesive 133 can adhere the main-side extension optical cable docking end E1211 and the main-side optoelectronic converter cable docking end E1121 in the main-side carrier docking space S131 to maintain the docking state between the main-side extension optical cable docking end E1211 and the main-side optoelectronic converter cable docking end E1121. Furthermore, the main-side optical cable connector adhesive 133 can provide a waterproof and sealed environment for the main-side extension optical cable docking end E1211 and the main-side optoelectronic converter cable docking end E1121, preventing the heat dissipation liquid L from penetrating. Therefore, if the signal transmission cable 1 is immersed in the heat dissipation liquid L along with the optical fiber network device, the main-side optical cable connector adhesive 133 can prevent the heat dissipation liquid L from penetrating into the signal transmission cable 1 through the docking point between the main-side extension optical cable docking end E1211 and the main-side optoelectronic converter cable docking end E1121, thereby enhancing the waterproof performance of the signal transmission cable 1. The main side optical cable connector cover 132 covers the main side optical cable connector carrier 131 to limit the flow range of the main side optical cable connector adhesive 133 so that the main side optical cable connector adhesive 133 is located in the main side carrier docking space S131 to meet aesthetic requirements.

[0111] It should be noted that, in the above embodiment, the primary-side optical cable connector adhesive 133 may be, but is not limited to, epoxy resin (EPOXY) adhesive.

The main-side photoelectric converter cable fiber 1122 and the extension optical cable fiber 122 can be made of glass or plastic and are responsible for transmitting the main-side optical signal. The main-side optical cable connector adhesive 133 adheres the main-side photoelectric converter cable fiber 1122 and the extension optical cable fiber 122 to maintain the relative positional relationship between the main-side photoelectric converter cable fiber 1122 and the extension optical cable fiber 122, thereby preventing the main-side photoelectric converter cable fiber 1122 and the extension optical cable fiber 122 from separating, thereby ensuring that the main-side extension optical cable docking end E1211 and the main-side photoelectric converter cable docking end E1121 meet the expected docking relationship.

[0113] At Figure 9 In the illustrated embodiment, the primary-side photoelectric converter cable 112 includes a primary-side photoelectric converter cable connector 1120. Accordingly, the extension optical cable 12 also includes a primary-side extension optical cable connector 1201. The primary-side photoelectric converter cable connector 1120 and the primary-side extension optical cable connector 1201 mate to transmit the primary-side optical signal. Accordingly, the primary-side optical cable connector adhesive 133 adheres the primary-side photoelectric converter cable connector 1120 and the primary-side extension optical cable connector 1201 to maintain the mating relationship between the primary-side photoelectric converter cable connector 1120 and the primary-side extension optical cable connector 1201.

[0114] In addition, the main-side optical-to-electrical converter cable 112 further includes a main-side optical-to-electrical converter cable cladding 1123 (Cladding). The main-side optical-to-electrical converter cable cladding 1123 surrounds the main-side optical-to-electrical converter cable optical fiber 1122 and has a lower refractive index than the main-side optical-to-electrical converter cable optical fiber 1122, thereby providing total internal reflection and ensuring that the main-side optical signal is transmitted within the main-side optical-to-electrical converter cable optical fiber 1122. Accordingly, the extension optical cable 12 further includes an extension optical cable cladding 123. The extension optical cable cladding 123 surrounds the extension optical fiber 122 and has a lower refractive index than the extension optical fiber 122, thereby providing total internal reflection and ensuring that the main-side optical signal is transmitted within the extension optical cable optical fiber 122.

[0115] It should be noted that the main-side optical cable connector adhesive 133 adheres the main-side photoelectric converter optical cable sheath 1123 and the extension optical cable sheath 123 to maintain the relative positional relationship between the main-side photoelectric converter optical cable sheath 1123 and the extension optical cable sheath 123, and avoids the main-side photoelectric converter optical cable sheath 1123 and the extension optical cable sheath 123 from being separated, thereby ensuring that the docking relationship between the main-side extension optical cable docking end E1211 and the main-side photoelectric converter optical cable docking end E1121 is as expected.

[0117] It should be noted that Figure 11 In the illustrated embodiment, if the main-side optical cable connector 13 is separated from the heat dissipation liquid L, the first main-side optical cable connector sub-adhesive barrier layer 1331 can prevent the heat dissipation liquid L from flowing between the first main-side optoelectronic converter optical cable gap G1121 and the first extension optical cable gap G121 through capillary phenomena, and then seeping out through the main-side optical cable connector 13 to pollute the environment.

In the above embodiment, the primary-side photoelectric converter cable buffer layer 1124 is wrapped around the primary-side photoelectric converter cable coating 1123 to provide protection for the primary-side photoelectric converter cable optical fiber 1122, thereby protecting the primary-side photoelectric converter cable optical fiber 1122 from mechanical damage and environmental influences. Correspondingly, the extension optical cable 12 further includes an extension optical cable buffer layer 124, wherein the extension optical cable buffer layer 124 can be made of a plastic material such as acrylic acid or a polymer. In the above embodiment, the extension optical cable buffer layer 124 is wrapped around the extension optical cable coating 123 to provide protection for the extension optical fiber 122, thereby protecting the extension optical fiber 122 from mechanical damage and environmental influences.

In the above embodiment, the extension optical cable strength member 125 surrounds the extension optical cable buffer layer 124 to provide additional mechanical strength to resist tension, thereby protecting the extension optical fiber 122 from tension.

[0123] It should be noted that the main side optical cable connector adhesive 133 adheres the main side photoelectric converter optical cable reinforcement layer 1125 and the extension optical cable reinforcement layer 125 to maintain the relative positional relationship between the main side photoelectric converter optical cable reinforcement layer 1125 and the extension optical cable reinforcement layer 125, and avoids the main side photoelectric converter optical cable reinforcement layer 1125 and the extension optical cable reinforcement layer 125 from being separated, thereby ensuring that the docking relationship between the main side extension optical cable docking end E1211 and the main side photoelectric converter optical cable docking end E1121 is as expected.

[0124] At Figure 6In the illustrated embodiment, a third main-side photoelectric converter cable gap G1123 is included between the main-side photoelectric converter cable reinforcement layer 1125 and the main-side photoelectric converter cable buffer layer 1124, and a third extension cable gap G123 is included between the extension cable reinforcement layer 125 and the extension cable buffer layer 124.

[0125] It should be noted that Figure 11 In the embodiment shown, if the main-side optical cable connector 13 is separated from the heat dissipation liquid L, the third main-side optical cable connector sub-adhesive barrier layer 1333 can prevent the heat dissipation liquid L from flowing between the third main-side optoelectronic converter optical cable gap G1123 and the third extension optical cable gap G123 through capillary phenomenon, and then seeping out through the main-side optical cable connector 13 to pollute the environment.

In the above embodiment, the extension optical cable outer sheath layer 126 surrounds the extension optical cable reinforcement layer 125 to provide outer layer protection, such as waterproofing, UV protection, and chemical corrosion resistance.

[0127] It should be noted that the main side optical cable connector adhesive 133 adheres the main side photoelectric converter optical cable outer sheath layer 1126 and the extension optical cable outer sheath layer 126 to maintain the relative positional relationship between the main side photoelectric converter optical cable outer sheath layer 1126 and the extension optical cable outer sheath layer 126, and avoids the main side photoelectric converter optical cable outer sheath layer 1126 and the extension optical cable outer sheath layer 126 from being separated, thereby ensuring that the docking relationship between the main side extension optical cable docking end E1211 and the main side photoelectric converter optical cable docking end E1121 is as expected.

[0128] At Figure 6 In the illustrated embodiment, a fourth main-side photoelectric converter cable gap G1124 is included between the main-side photoelectric converter cable outer sheath layer 1126 and the main-side photoelectric converter cable reinforcement layer 1125, and a fourth extension cable gap G124 is included between the extension cable outer sheath layer 126 and the extension cable reinforcement layer 125.

[0129] It should be noted that Figure 11 In the embodiment shown, if the main-side optical cable connector 13 leaves the heat dissipation liquid L, the fourth main-side optical cable connector sub-adhesive barrier layer 1334 can prevent the heat dissipation liquid L from flowing between the fourth main-side optoelectronic converter optical cable gap G1124 and the fourth extension optical cable gap G124 through capillary phenomena, and then seeping out through the main-side optical cable connector 13 to pollute the environment.

[0130] At Figure 2 In the illustrated embodiment, the signal transmission cable 1 further includes a primary-side photoelectric converter 14 .

[0131] The secondary-side photoelectric converter 14 includes a primary-side photoelectric conversion module 141 and a primary-side photoelectric converter optical cable 142. The secondary-side photoelectric conversion module 141 can convert a primary-side electrical signal into a primary-side optical signal, or alternatively, the secondary-side photoelectric conversion module 141 can convert the secondary-side optical signal into the secondary-side electrical signal. The secondary-side photoelectric converter optical cable 142 can transmit the secondary-side optical signal and includes a primary-side photoelectric converter optical cable docking end E1421.

[0132] Regarding the extension optical cable 12, Figure 8 In the embodiment shown, the other side of the extension optical cable 12 includes a primary extension optical cable docking end E1212. In the above embodiment, the secondary extension optical cable docking end E1212 includes a structure that can provide docking for other optical cables.

[0133] Regarding the secondary side optical cable connector 15, Figure 8 In the illustrated embodiment, the secondary optical cable connector 15 includes a primary optical cable connector carrier 151 , a primary optical cable connector cover 152 , and a primary optical cable connector adhesive 153 .

[0134] In the above embodiment, the secondary-side extension optical cable docking end E1212 can dock with the secondary-side optoelectronic converter cable docking end E1421 in the secondary-side carrier docking space S151, allowing the secondary-side optoelectronic converter cable 142 to transmit the secondary-side optical signal from the secondary-side extension optical cable docking end E1212 to the secondary-side extension optical cable docking end E1212 and into the extension optical cable 12. The extension optical cable 12 can be extended to increase the transmission distance of the secondary-side optical signal. It should be noted that the length of the extension optical cable 12 can be adjusted according to the distance between the secondary-side optoelectronic converter module 141 and the optical fiber network device. In other words, the length of the extension optical cable 12 can be adjusted according to the transmission distance of the secondary-side optical signal. This means that the length of the secondary-side optoelectronic converter cable 142 does not need to be changed depending on the usage scenario or method. Therefore, the secondary-side optoelectronic converter 14 can be mass-produced, reducing manufacturing costs.

[0135] Furthermore, the secondary optical cable connector adhesive 153 can adhere the secondary extension optical cable mating end E1212 and the secondary optoelectronic converter cable mating end E1421 in the secondary carrier mating space S151 to maintain the mating state of the secondary extension optical cable mating end E1212 and the secondary optoelectronic converter cable mating end E1421. Furthermore, the secondary optical cable connector adhesive 153 can provide a waterproof and sealed environment for the secondary extension optical cable mating end E1212 and the secondary optoelectronic converter cable mating end E1421, preventing the heat dissipation liquid L from penetrating. Therefore, if the signal transmission cable 1 is immersed in the heat dissipation liquid L along with the optical fiber network device, the secondary optical cable connector adhesive 153 can prevent the heat dissipation liquid L from penetrating into the signal transmission cable 1 through the joint between the secondary extension optical cable mating end E1212 and the secondary optoelectronic converter cable mating end E1421, thereby enhancing the waterproof performance of the signal transmission cable 1.

This ensures that the secondary-side extension optical cable mating end E1212 and the secondary-side photoelectric converter cable mating end E1421 meet the intended connection.

The secondary-side optical fiber cable cladding 1423 surrounds the secondary-side optical fiber cable 1422 and has a lower refractive index than the secondary-side optical fiber cable 1422, thereby providing total internal reflection (TIR) ​​to ensure that the secondary-side optical signal is transmitted within the secondary-side optical fiber cable 1422. Accordingly, the extension optical cable 12 further includes an extension optical fiber cladding 123. The extension optical fiber cladding 123 surrounds the extension optical fiber 122 and has a lower refractive index than the extension optical fiber 122, thereby providing total internal reflection (TIR) ​​to ensure that the secondary-side optical signal is transmitted within the extension optical fiber cable 122.
