Description

Technical Field

[0001] This application relates to the field of optical devices, and more particularly to an optical communication device, an optical transmission component, an optical network, and male and female optical connectors. Background Technology

[0002] With the continuous development of communication technology, fiber optic communication is becoming increasingly widespread. Optical connectors are common devices in fiber optic communication; they are reusable passive devices used to connect two optical fibers or cables to form a continuous optical path. Optical connectors are used in applications such as artificial intelligence (AI) clusters and high-performance computing (HPC) clusters. In these applications, optical connectors significantly impact the reliability and performance of optical transmission systems.

[0003] Dust can cause optical connectors to fail, and dust is inevitably introduced during the assembly process. Therefore, minimizing the impact of dust on optical connectors is a problem that needs to be solved. Summary of the Invention

[0004] This application provides an optical communication device, an optical transmission component, an optical network, and male and female optical connectors. Reducing the impact of dust on optical connectors is a current problem that needs to be solved.

[0005] In a first aspect, this application provides a male optical connector. The male optical connector includes a ferrule, a plurality of first optical waveguides, and a plurality of second optical waveguides. The outer peripheral surface of the ferrule includes a first surface and a second surface, which are disposed opposite to each other. The first surface has a plurality of first light-transmitting areas; the second surface has a plurality of second light-transmitting areas. The ferrule surrounds the outer peripheral surface of each of the first optical waveguides, and one of the first light-transmitting areas is used to emit a light beam from one of the first optical waveguides. The ferrule surrounds the outer peripheral surface of each of the second optical waveguides, and one of the second light-transmitting areas is used to emit a light beam from one of the second optical waveguides.

[0006] During the connection process between the male and female optical connectors, if dust is present in the environment, it will tend to accumulate on the end face of the ferrule (i.e., the free end face) due to capillary effect. In the embodiments of this application, both the first and second light-transmitting areas are located on the outer peripheral surface of the ferrule. Therefore, the probability of dust adhering to the first and second light-transmitting areas is relatively low, reducing the impact of dust on the light beam transmitted within the male optical connector. Furthermore, since the outer peripheral surface of the ferrule is larger than the free end face, the first and second light-transmitting areas can be cleaned more effectively, making dust prevention easier. This improves the dust holding capacity of the male optical connector and enhances its reliability.

[0007] In conjunction with the first aspect, in some feasible embodiments, the ferrule includes multiple groups of light-transmitting areas, one group of light-transmitting areas including a first light-transmitting area and a second light-transmitting area. The vertical projection of the first light-transmitting area in the group of light-transmitting areas onto the second surface overlaps with the second light-transmitting area in the same group of light-transmitting areas.

[0008] Thus, the first and second light-transmitting areas are positioned opposite each other, and multiple first and second light-transmitting areas are symmetrically arranged. When the male and female optical connectors are connected, the forces exerted by the female connector on the first and second light-transmitting areas within the same light-transmitting area group are in opposite directions. This promotes uniform force distribution on the male connector and improves its reliability.

[0009] In conjunction with the first aspect, in some feasible ways, multiple first light-transmitting areas are arranged in multiple rows on the first surface. In this way, the space of the first surface can be fully utilized.

[0010] In conjunction with the first aspect, in some feasible ways, multiple second light-transmitting areas are arranged in multiple rows on the second surface. In this way, the space of the second surface can be fully utilized.

[0011] In conjunction with the first aspect, in some feasible ways, the number of the first optical waveguide and the second optical waveguide are the same.

[0012] In conjunction with the first aspect, in some feasible embodiments, the male optical connector further includes a plurality of third optical waveguides. The number of third optical waveguides is the same as that of the first optical waveguides. The ends of the first optical waveguides away from the first light-transmitting area and the ends of the second optical waveguides away from the second light-transmitting area are both connected to the third optical waveguides; the first optical waveguides are used to transmit a portion of the light beam from the third optical waveguides, and the second optical waveguides are used to transmit another portion of the light beam from the same third optical waveguide.

[0013] Thus, if one of the first and second optical waveguides connected to the same third optical waveguide becomes contaminated with dust, the light beam within the third waveguide can be transmitted from the other uncontaminated waveguide. Only when the light beams output from both the first and second optical waveguides connected to the same third waveguide become contaminated with dust will the light beam transmitted within that third waveguide fail. This reduces the probability of optical signal failure, increases the dust tolerance of the optical connector male, and improves reliability.

[0014] In conjunction with the first aspect, in some feasible embodiments, the male optical connector further includes: a first polarization converter and a second polarization converter. The first polarization converter is used to receive a light beam from the first light-transmitting area and output first polarized light. The second polarization converter is used to receive a light beam from the second light-transmitting area and output second polarized light, wherein the polarization directions of the first polarized light and the second polarized light are not parallel.

[0015] The polarization direction of the first polarized light is not parallel to that of the second polarized light, which effectively overcomes the loss caused by interference during the beam combining process of the first and second light waves.

[0016] In conjunction with the first aspect, in some feasible methods, the polarization direction of the first polarized light and the polarization direction of the second polarized light are perpendicular to each other. This effectively overcomes the losses caused by interference between the first and second polarized light during beam combining.

[0017] In conjunction with the first aspect, in some feasible embodiments, the male optical connector further includes: a first mode converter and a second mode converter. The first mode converter is used to convert the light beam from the first light-transmitting area into a first multimode signal light output; the second mode converter is used to convert the light beam from the second light-transmitting area into a second multimode signal light output; the modes in the first multimode signal light and the modes in the second multimode signal light are different.

[0018] Because the modes in the first multimode signal light and the modes in the second multimode signal light are different, the loss caused by interference during the beam combining process of the beams emitted from the first and second optical wavesguides, which are transmitted by the same third optical waveguide, is effectively improved, and the loss of the beam passing through the male head of the optical connector is reduced.

[0019] In conjunction with the first aspect, in some feasible implementations, the male optical connector further includes: multiple polarization beam splitters. Each polarization beam splitter is connected to a corresponding third optical waveguide; the polarization beam splitter is used to split a beam from the third optical waveguide into third polarized light and fourth polarized light, the first optical waveguide is used to transmit the third polarized light; the second optical waveguide is used to transmit the fourth polarized light; the polarization directions of the third polarized light and the fourth polarized light are not parallel.

[0020] Since the polarization directions of the third polarized light and the fourth polarized light are not parallel, the loss caused by interference during the beam combining process of the first and second light waveguides is effectively overcome.

[0021] In conjunction with the first aspect, in some feasible ways, the polarization directions of the third polarized light and the fourth polarized light are perpendicular to each other.

[0022] In conjunction with the first aspect, in some feasible ways, the first end of the first optical waveguide extends to the first surface, and the first light-transmitting region is located on the end face of the first end.

[0023] Thus, during the transmission of the light beam from the first optical waveguide to the first transparent region, the transmission medium of the beam is uniform, reducing losses. Furthermore, during this transmission process, the male connector of the optical connector does not require other optical components, simplifying the fabrication process and reducing costs.

[0024] In conjunction with the first aspect, in some feasible ways, the first end of the second optical waveguide extends to the first surface, and the second light-transmitting region is located at the end face of the first end of the second optical waveguide.

[0025] Thus, during the transmission of the light beam to the second transparent region in the second optical waveguide, the transmission medium of the beam is uniform, reducing losses. Furthermore, during this transmission process, the male connector of the optical connector does not require other optical components, simplifying the fabrication process and reducing costs.

[0026] In conjunction with the first aspect, in some feasible embodiments, the ferrule is provided with a plurality of light-transmitting holes, each light-transmitting hole having an opening on the first surface, and the first light-transmitting area being located within the opening. The male optical connector also includes a reflective element. The reflective element is located within the ferrule; the reflective element is used to reflect a light beam from the first optical waveguide to the light-transmitting hole, and the light-transmitting hole is used to allow the light beam from the reflective element to exit from the first light-transmitting area.

[0027] In this way, the first and second optical waveguides can remain straight within the ferrule. With the aid of the aforementioned reflective element and light-transmitting aperture, the light beams from the first and second optical waveguides can also be transmitted to the outer periphery of the ferrule.

[0028] In conjunction with the first aspect, in some feasible embodiments, the male optical connector further includes: a plurality of lenses, each of which is connected to the ferrule, one of which covers a first light-transmitting area, and the lens is used to collimate and expand the beam from the first light-transmitting area before outputting it.

[0029] Thus, even if dust is present on the surface of the first lens away from the first light-transmitting area, the influence of the dust on the beam can be reduced because the first lens amplifies the size of the beam spot. Furthermore, during the connection of the male and female optical connectors, the first lens and the female connector can be better aligned. The beam collimated by the first lens can be transmitted to the female connector more effectively, reducing losses.

[0030] In conjunction with the first aspect, in some feasible embodiments, the male optical connector further includes: an identification portion disposed on the ferrule, the identification portion being used to indicate the position of one of the plurality of first light-transmitting areas.

[0031] Thus, during the assembly of the male and female optical connectors, the location of the first light-transmitting area marked by the identification part can be quickly identified by the identification part. This helps to reduce assembly time.

[0032] In conjunction with the first aspect, in some feasible embodiments, the male optical connector also includes a stop portion that protrudes from the first surface, and the first light-transmitting area is closer to the free end of the ferrule than the stop portion.

[0033] Because the first light-transmitting area is closer to the free end of the ferrule than the stop, during the assembly of the male and female optical connectors, the free end of the ferrule extends into the female optical connector. When the stop and the female optical connector come into contact, the ferrule and the female optical connector are successfully mated. In this way, the stop can indicate whether the ferrule is assembled in the correct position, simplifying the assembly process.

[0034] In conjunction with the first aspect, in some feasible ways, the ferrule is a square prism. This results in a simple ferrule structure, ease of manufacturing, and convenient assembly between the ferrule and the optical connector female.

[0035] In conjunction with the first aspect, in some feasible embodiments, the ferrule includes a connecting shell and a plurality of embedded portions, one of which surrounds the outer peripheral surface of a first optical waveguide and the outer peripheral surface of a second optical waveguide; each embedded portion is provided with a first light-transmitting area and a second light-transmitting area. A gap exists between adjacent embedded portions, and all of the plurality of embedded portions are connected to the connecting shell.

[0036] Because there are gaps between the multiple embedded parts, the weight of the ferrule can be reduced. Furthermore, during the fabrication of the male optical connector, a first optical waveguide and a second optical waveguide can be connected to an embedded part, and then multiple embedded parts can be connected to a connecting shell to assemble the male optical connector. The connecting shell and embedded parts can be assembled according to the required number of first optical waveguides in the male optical connector.

[0037] Secondly, this application provides an optical connector female. The optical connector female includes a ferrule, a plurality of first optical waveguides, and a plurality of second optical waveguides. One end of the ferrule is provided with a receiving groove; the receiving groove includes a first inner peripheral wall and a second inner peripheral wall disposed opposite to each other. The first inner peripheral wall is provided with a plurality of first light-transmitting areas; the second inner peripheral wall is provided with a plurality of second light-transmitting areas. The ferrule surrounds the outer peripheral surface of each of the first optical waveguides, and one of the first light-transmitting areas is used to emit a light beam from one of the first optical waveguides. The ferrule surrounds the outer peripheral surface of each of the second optical waveguides, and one of the second light-transmitting areas is used to emit a light beam from one of the second optical waveguides.

[0038] Similar to the aforementioned male optical connector, if dust is present in the environment, it will tend to accumulate on the bottom wall of the receiving groove due to capillary effect. In the embodiments of this application, both the first and second light-transmitting areas are located on the first and second inner peripheral walls of the ferrule. Therefore, the probability of dust adhering to the first and second light-transmitting areas is relatively low. This reduces the impact of dust on the light beam transmitted within the female optical connector. Furthermore, the inner peripheral wall of the receiving groove is easier to clean than the bottom wall, further reducing dust accumulation. Reducing the impact of dust improves the dust-holding capacity of the female optical connector and enhances its reliability.

[0039] In conjunction with the second aspect, in some feasible embodiments, the ferrule includes multiple groups of light-transmitting areas, one of which includes a first light-transmitting area and a second light-transmitting area. The vertical projection of the first light-transmitting area in the group onto the second inner peripheral wall overlaps with the second light-transmitting area in the group.

[0040] In conjunction with the second aspect, in some feasible ways, multiple first light-transmitting zones are arranged in multiple rows on the first inner peripheral wall.

[0041] In conjunction with the second aspect, in some feasible ways, the number of the first optical waveguide and the second optical waveguide are the same.

[0042] In conjunction with the second aspect, in some feasible embodiments, the optical connector female also includes a plurality of third optical waveguides. The number of third optical waveguides is the same as that of the second optical waveguides. The ends of the first optical waveguides away from the first light-transmitting area and the ends of the second optical waveguides away from the second light-transmitting area are both connected to the third optical waveguides; the first optical waveguide is used to transmit a portion of the light beam from the third optical waveguide, and the second optical waveguide is used to transmit another portion of the light beam from the third optical waveguide.

[0043] In conjunction with the second aspect, in some feasible implementations, the optical connector female also includes: a first polarization converter and a second polarization converter. The first polarization converter is connected to the end of the first optical waveguide away from the first light-transmitting region; the second polarization converter is connected to the end of the second optical waveguide away from the second light-transmitting region; the first polarization converter is used to output first polarized light to the first optical waveguide; the second polarization converter is used to output second polarized light to the second optical waveguide, wherein the polarization directions of the first polarized light and the second polarized light are not parallel.

[0044] In conjunction with the second aspect, in some feasible ways, the polarization direction of the first polarized light and the polarization direction of the second polarized light are perpendicular to each other.

[0045] In conjunction with the second aspect, in some feasible implementations, the optical connector female also includes: a first mode converter and a second mode converter. The first mode converter is used to convert the light beam from the first light-transmitting area into a first multimode signal light output; the second mode converter is used to convert the light beam from the second light-transmitting area into a second multimode signal light output; the modes in the first multimode signal light and the modes in the second multimode signal light are different.

[0046] In conjunction with the second aspect, in some feasible implementations, the optical connector female also includes: multiple polarization beam splitters. Each polarization beam splitter is connected to a corresponding third optical waveguide; the polarization beam splitter is used to split the beam from the third optical waveguide into third polarized light and fourth polarized light, the first optical waveguide is used to transmit the third polarized light; the second optical waveguide is used to transmit the fourth polarized light; the polarization directions of the third polarized light and the fourth polarized light are not parallel.

[0047] Since the polarization directions of the third polarized light and the fourth polarized light are not parallel, the loss caused by interference during the beam combining process of the first and second light waveguides is effectively overcome.

[0048] In conjunction with the second aspect, in some feasible ways, the polarization directions of the third polarized light and the fourth polarized light are perpendicular to each other.

[0049] In conjunction with the second aspect, in some feasible ways, the first end of the first optical waveguide extends to the first inner peripheral wall, and the first light-transmitting area is located on the end face of the first end.

[0050] In conjunction with the second aspect, in some feasible embodiments, the ferrule is provided with a plurality of light-transmitting holes, each light-transmitting hole having an opening on the first inner peripheral wall, and the first light-transmitting area being located within the opening. The optical connector female also includes: a reflective element located within the ferrule; the reflective element is used to reflect a light beam from the first optical waveguide to the light-transmitting hole, and the light-transmitting hole is used to allow light beams originating from the reflective element to exit from the light-transmitting area.

[0051] In conjunction with the second aspect, in some feasible embodiments, the optical connector female also includes: a plurality of lenses, each of which is connected to the ferrule, one of which covers one of the first light-transmitting areas, and the lens is used to collimate and expand the beam from the first light-transmitting area before outputting it.

[0052] In conjunction with the second aspect, in some feasible embodiments, the optical connector female also includes: an identification portion disposed on the ferrule, the identification portion being used to indicate the position of one of the plurality of first light-transmitting areas.

[0053] In conjunction with the second aspect, in some feasible ways, the receiving slot is a square slot.

[0054] Thirdly, this application provides an optical communication device. The optical communication device includes: an optical module and any of the male optical connectors provided in the first aspect, wherein the optical module is connected to the male optical connector. Alternatively, the optical communication device includes: an optical module and any of the female optical connectors provided in the second aspect, wherein the optical module is connected to the female optical connector. Since both male and female optical connectors have the advantages of low probability of optical signal failure and high dust tolerance, the optical communication device including the male or female optical connector has high dust tolerance and high reliability.

[0055] Fourthly, this application provides an optical transmission component. The optical transmission component includes: any of the male optical connectors provided in the first aspect and any of the female optical connectors provided in the second aspect, wherein the male optical connector is connected to the female optical connector.

Detailed Implementation

[0084] To make the objectives, technical solutions, and advantages of this application clearer, the application will now be described in further detail with reference to the accompanying drawings.

[0085] In the following description, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0086] Furthermore, in this application, directional terms such as "upper" and "lower" are defined relative to the orientation of the components shown in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the orientation of the components in the accompanying drawings.

[0087] Figure 1a This is a schematic diagram of the structure of an optical network 10. Figure 1a In the example, the optical network 10 includes a first optical communication device 11, a second optical communication device 12, and an optical transmission component 13. The first optical communication device 11 and the second optical communication device 12 are interconnected through the optical transmission component 13 to achieve optical communication.

[0088] For example, the optical network 10 can be a passive optical network (PON), such as a gigabit-capable passive optical network (GPON), a 10-gigabit-capable symmetric passive optical network (XGS-PON), or a 50-gigabit-capable passive optical network (50GPON), etc.

[0089] The aforementioned Passive Optical Network (PON) refers to an optical distribution network (ODN) between the OLT (optical line termination) and the optical network unit (ONU), without any active electronic devices.

[0090] The aforementioned optical distribution network (ODN) is a fiber-to-the-home (FTTH) network based on PON equipment. Its function is to provide an optical transmission channel between the OLT and ONU.

[0091] The embodiments of this application do not limit the type of the first optical communication device 11. For example, the first optical communication device 11 can be a single board, a backplane, a box-type device, or a frame-type device, etc.

[0092] For example, the optical network 10 can be used for artificial intelligence (AI), transport networks, data centers, etc.

[0093] During the assembly of the optical network 10, the first optical communication device 11 is connected to the optical transmission component 13 via an optical connector. The second optical communication device 12 is connected to the optical transmission component 13 via an optical connector.

[0094] Taking the connection between the first optical communication device 11 and the optical transmission component 13 as an example, the first optical communication device 11 includes an optical module and a male optical connector 100, which are connected. The optical transmission component 13 includes an optical cable and a female optical connector 200, which are connected. The male optical connector 100 and the female optical connector 200 are connected to realize the connection between the first optical communication device 11 and the optical transmission component 13.

[0095] It is understood that the first optical communication device 11 may also include an optical module and an optical connector female 200, and the optical transmission component 13 may include an optical cable and an optical connector male 100. The optical connector male 100 and the optical connector female 200 are connected, and similarly, the connection between the first optical communication device 11 and the optical transmission component 13 can be realized.

[0096] The connection method between the second optical communication device 12 and the optical transmission component 13 is similar and will not be described again here.

[0097] In some embodiments, the optical transmission component 13 includes an optical cable, a male optical connector 100, and a female optical connector 200. The male optical connector 100 is disposed at one end of one segment of the optical cable, and the female optical connector 200 is disposed at one end of another segment of the optical cable. The male optical connector 100 and the female optical connector 200 are connected to each other, thereby achieving the connection between the two segments of the optical cable.

[0098] Figure 1b This is a schematic diagram illustrating the connection between a male optical connector 100 and a female optical connector 200. (Please refer to...) Figure 1b The optical connector male head 100 also includes a male end connection shell 14, which is sleeved on the optical connector male head 100.

[0099] The female optical connector 200 also includes a female end connecting shell 15, which is sleeved on the female optical connector 200. The male optical connector 100 and the female optical connector 200 are mated together, and the male end connecting shell 14 and the female end connecting shell 15 are connected. Figure 1b The arrows in the diagram represent one direction of light transmission, allowing the light beam to travel from the male connector 100 to the female connector 200. Because the optical path is reversible, the light beam can travel from the female connector 200 to the male connector 100.

[0100] This application embodiment does not limit the structure of the male connector shell 14 and the female connector shell 15; they can be connected as long as they are compatible. The structure of the male connector shell 14 and the female connector shell 15 can be configured according to the type of the optical connector male head 100. This application embodiment does not limit the type of the optical connector male head 100. For example, the type of the optical connector male head 100 can be a Mechanical Transfer (MT) connector, a Lucent connector (LC), a Multi-fiber Push On (MPO) connector, an MT-Push On (MTP) connector, a square connector (SC), etc.

[0101] Similarly, the structure of the female connector shell 15 can be configured according to the type of the optical connector female head 200. This application embodiment does not limit the type of the optical connector female head 200. For example, the type of the optical connector female head 200 can be a Mechanical Transfer (MT) connector, a Lucent connector (LC), a Multi-fiber Push On (MPO) connector, an MT-Push on (MTP) connector, a square connector (SC), etc.

[0102] During the connection process between the male connector 100 and the female connector 200, dust is inevitably introduced, which can cause optical network failures. For example, dust can increase optical signal transmission loss, cause optical signal transmission errors, reduce the performance and lifespan of the optical network, lead to optical link failures, and cause momentary optical interface interruptions.

[0103] The optical connector male 100 and optical connector female 200 provided in this application embodiment can reduce the impact of dust and improve network reliability.

[0104] Figure 2a This is a schematic diagram of the structure of a male optical connector 100 provided in an embodiment of this application. Figure 2b for Figure 2a A schematic diagram of the cross-section of AA. Please refer to [link / reference]. Figure 2b The male optical connector 100 includes a ferrule 110, a plurality of first optical waveguides 120, and a plurality of second optical waveguides 130. The ferrule 110 has an outer peripheral surface, which includes a first surface 101 and a second surface 102, which are disposed opposite to each other. The first surface 101 is provided with a plurality of first light-transmitting areas 111, and the second surface 102 is provided with a plurality of second light-transmitting areas 112.

[0105] The outer peripheral surface of the ferrule 110 refers to the surface connecting the two ends of the ferrule 110 along the extension direction of the first optical waveguide 120.

[0106] A ferrule 110 surrounds the outer peripheral surface of each first optical waveguide 120, and a first light-transmitting area 111 is used to emit a light beam from a first optical waveguide 120. In other words, the light beam transmitted by the first optical waveguide 120 exits the ferrule 110 through the first light-transmitting area 111. Due to the reversibility of the optical path, the first optical waveguide 120 transmits the light beam entering the optical connector male 100 from the first light-transmitting area 111. The following description uses the example of the light beam transmitted by the first optical waveguide 120 exiting the ferrule 110 through the first light-transmitting area 111 as an example.

[0107] The ferrule 110 surrounds the outer peripheral surface of each second optical waveguide 130, and a second light-transmitting area 112 is used to emit a light beam from a second optical waveguide 130. In other words, the light beam transmitted by the second optical waveguide 130 exits the ferrule 110 through the second light-transmitting area 112. Due to the reversibility of the optical path, the second optical waveguide 130 transmits the light beam entering the optical connector male 100 from the second light-transmitting area 112.

[0108] During the connection process between the male optical connector 100 and the female optical connector, if dust is present in the environment, it will accumulate more on the end face of the ferrule 110, i.e., the free end face of the ferrule 110, due to capillary effect. In the embodiments of this application, both the first light-transmitting area 111 and the second light-transmitting area 112 are located on the outer peripheral surface of the ferrule 110. Therefore, the probability of dust adhering to the first light-transmitting area 111 and the second light-transmitting area 112 is relatively small. This reduces the impact of dust on the light beam transmitted within the male optical connector 100. In addition, the outer peripheral surface of the ferrule 110 is larger than the free end face of the ferrule 110, allowing for better cleaning of the first light-transmitting area 111 and the second light-transmitting area 112, making dust prevention easier to implement. This helps to improve the dust holding capacity of the male optical connector 100 and enhance its reliability.

[0109] This application does not limit the material of the insert 110. For example, the material of the insert 110 may be ceramic, plastic, or rubber, etc.

[0110] In embodiments of this application, the insert 110 is shaped like a polygonal prism. For example, the insert 110 may be a square prism, a hexagonal prism, or a similar shape. Alternatively, the insert 110 may be an irregular polygonal prism shape. In some embodiments of this application, the insert 110 is a cuboid.

[0111] Exemplarily, in embodiments of this application, the first optical waveguide 120 can be an integrated optical waveguide, which can be a planar (thin film) dielectric waveguide or a strip-shaped dielectric waveguide. For example, the first optical waveguide 120 can be formed by an etching process on a polyimide (PI) thin film. In some embodiments, the first optical waveguide 120 can be a cylindrical optical waveguide, which can also be referred to as an optical fiber.

[0112] Exemplarily, the first optical waveguide 120 includes a core and a cladding. The cladding surrounds the outer peripheral surface of the core. In some embodiments, the core is made of silicon dioxide (SiO2), and the cladding is doped silicon dioxide (SiO2), where the doping element can be, for example, a pentavalent element such as nitrogen or phosphorus. In some embodiments, the core material can be silicon dioxide, doped silicon dioxide, polycarbonate, polymethyl methacrylate, polyacrylate copolymer, fluorinated olefin polymer, or fluorinated methyl methacrylate, etc. The cladding material can be silicon dioxide, doped silicon dioxide, fluorinated olefin polymer, fluorinated methyl methacrylate, polycarbonate, polymethyl methacrylate, or polyacrylate copolymer, etc.

[0113] For example, the first optical waveguide 120 can be a single-mode fiber or a multimode fiber. For instance, the core diameter of the first optical waveguide 120 can be 50 μm or 62.5 μm.

[0114] The structure, material, and dimensions of the second optical waveguide 130 are described in the preceding description of the first optical waveguide 120. They will not be repeated here.

[0115] The first surface 101 and the second surface 102 of the ferrule 110 are arranged opposite each other, meaning that the first surface 101 and the second surface 102 are located on opposite sides of the ferrule 110.

[0116] In some embodiments of this application, the transmission direction of the light beam emitted from the first light-transmitting area 111 is perpendicular to the first surface 101. In some embodiments, the angle between the transmission direction of the light beam emitted from the first light-transmitting area 111 and the first surface 101 can be 60° to 100°. For example, the angle between the transmission direction of the light beam emitted from the first light-transmitting area 111 and the first surface 101 can be 60°, 70°, 80°, 90°, 95°, 98°, or 100°, etc.

[0117] The embodiments of this application do not limit the arrangement of the first light-transmitting area 111 on the first surface 101. Figure 2bIn the example, multiple first light-transmitting areas 111 are arranged in a row on the first surface 101.

[0118] Figure 2b In the middle, multiple first light-transmitting zones 111 are set at intervals.

[0119] In some embodiments of this application, a plurality of first light-transmitting areas 111 may be adjacent to each other. In other words, the first surface 101 has a light-transmitting portion, which can be regarded as being formed by connecting a plurality of first light-transmitting areas 111. One first light-transmitting area 111 is used to emit a light beam from a first optical waveguide 120.

[0120] The embodiments of this application do not limit the number of the first light-transmitting area 111 and the second light-transmitting area 112. The number is set according to the number of optical signals in the optical link. For example, the number of the first light-transmitting area 111 can be 2, 3, 4, or more. The number of the second light-transmitting area 112 can also be 2, 3, 4, or more. For instance, the number of both the first light-transmitting area 111 and the second light-transmitting area 112 is 12.

[0121] Furthermore, the number of first light-transmitting areas 111 and the number of second light-transmitting areas 112 may be equal or unequal. In some embodiments, the number of first light-transmitting areas 111 and the number of second light-transmitting areas 112 are equal.

[0122] In some embodiments, the number of first light-transmitting areas 111 and the number of second light-transmitting areas 112 are equal. One first light-transmitting area 111 and one second light-transmitting area 112 constitute a light-transmitting area group 001. In other words, the ferrule 110 includes a plurality of light-transmitting area groups 001, and one light-transmitting area group 001 includes one first light-transmitting area 111 and one second light-transmitting area 112.

[0123] like Figure 2b As shown, the vertical projection of the first light-transmitting area 111 in the light-transmitting area group 001 onto the second surface 102 overlaps with the second light-transmitting area 112 in the same light-transmitting area group 001. In other words, the first light-transmitting area 111 and the second light-transmitting area 112 in the same light-transmitting area group 001 are located at opposite ends of a reference line, which is perpendicular to the second surface 102.

[0124] For example, the insert 110 has a reference surface, and both the first surface 101 and the second surface 102 are parallel to the reference surface. The distance from the first surface 101 to the reference surface is equal to the distance from the second surface 102 to the reference surface. The first light-transmitting area 111 and the second light-transmitting area 112 in the same light-transmitting area group 001 are symmetrical about the reference surface.

[0125] Thus, the first light-transmitting area 111 and the second light-transmitting area 112 are arranged opposite to each other, and multiple first light-transmitting areas 111 and multiple second light-transmitting areas 112 are symmetrically arranged. When the male optical connector 100 and the female optical connector are connected, the forces exerted by the female optical connector on the first light-transmitting area 111 and the second light-transmitting area 112 in the same light-transmitting area group 001 are in opposite directions. This facilitates uniform force distribution on the male optical connector 100 and improves the reliability of the male optical connector 100.

[0126] The aforementioned vertical projection of the first light-transmitting area 111 onto the second surface 102 refers to the projection of the first light-transmitting area 111 onto the second surface 102 along a direction perpendicular to the second surface 102, with the first light-transmitting area 111 as the main projection subject.

[0127] In addition, the male connector 100 has a simple structure and the advantages of simple assembly and low cost.

[0128] In some embodiments of this application, the vertical projection of the first light-transmitting area 111 in the light-transmitting area group 001 onto the second surface 102 may not overlap with the second light-transmitting area 112 in the same light-transmitting area group 001.

[0129] In some embodiments of this application, the plurality of first light-transmitting areas 111 may be arranged in multiple rows on the first surface 101. In other words, the first surface 101 includes multiple rows of first light-transmitting areas 111. In this way, the space of the first surface 101 can be fully utilized.

[0130] The number of first light-transmitting areas 111 in each row can be the same or different. For example, the first surface 101 includes 2, 3 or more rows of first light-transmitting areas 111.

[0131] Figure 3a This is a schematic diagram of another optical connector male head 100 provided in an embodiment of this application. Figure 3b for Figure 3a A schematic cross-sectional view of section BB. Please refer to [link / reference]. Figure 3b The first surface 101 is provided with two rows of first light-transmitting areas, and each row of first light-transmitting areas includes multiple first light-transmitting areas 111.

[0132] In this way, the space of the first surface 101 can be fully utilized, and the optical connector male 100 can be equipped with more first optical waveguides 120 and second optical waveguides 130.

[0133] Figure 3b In the same light-transmitting area group 001, the first light-transmitting area 111 and the second light-transmitting area 112 are located at the two ends of the reference line, which is perpendicular to the second surface 102.

[0134] In some embodiments, the arrangement of the first light-transmitting area 111 on the first surface 101 and the arrangement of the second light-transmitting area 112 on the second surface 102 may be different.

[0135] Figure 2b and Figure 3b In the example, the first end of the first optical waveguide 120 extends to the first surface 101 of the ferrule 110. The first light-transmitting region 111 is located at the first end of the first optical waveguide 120. In other words, the first optical waveguide 120 is bent and extends from the interior of the ferrule 110 to the first surface 101.

[0136] Thus, during the transmission of the light beam from the first optical waveguide 120 to the first transparent region 111, the transmission medium of the light beam is uniform, reducing losses. Furthermore, during this transmission process, the male connector 100 does not require other optical components, simplifying the fabrication process and reducing costs.

[0137] Similarly, the first end of the second optical waveguide 130 extends to the second surface 102 of the ferrule 110. The second light-transmitting area 112 is located at the first end of the second optical waveguide 130. In other words, the second optical waveguide 130 is bent and extends from the interior of the ferrule 110 to the second surface 102.

[0138] The embodiments of this application do not limit the bending angle of the first optical waveguide 120. For example, the first optical waveguide 120 may be bent at 70°-100° within the insert 110. For example, the first optical waveguide 120 may be bent at 70°, 80°, 85°, 90°, 95°, or 100° within the insert 110. The bending angle of the second optical waveguide 130 is similar.

[0139] Please refer to it again. Figure 2b and Figure 3b In some embodiments, the male optical connector 100 further includes multiple lenses, each of which is connected to the ferrule, and one lens is used to cover one of the first light-transmitting areas 111. In the embodiments of this application, for ease of distinction, the lens covering the first light-transmitting area 111 is referred to as the first lens 121, and the lens covering the second light-transmitting area 112 is referred to as the second lens 123.

[0140] The male optical connector 100 may further include a plurality of first lenses 121, all of which are connected to the ferrule 110. Each first lens 121 covers a first light-transmitting area 111. The first lens 121 is used to collimate and expand the light beam from the first light-transmitting area 111 before outputting it. Thus, even if dust is present on the surface of the first lens 121 away from the first light-transmitting area 111, the influence of the dust on the light beam can be reduced because the first lens 121 expands the size of the light beam spot. Furthermore, during the connection of the male optical connector 100 and the female optical connector, the first lens 121 and the female optical connector can be better aligned. The light beam collimated by the first lens 121 can be transmitted to the female optical connector better, reducing losses.

[0141] Similarly, the male connector 100 may also include a plurality of second lenses 123, all of which are connected to the ferrule 110. One second lens 123 covers a second light-transmitting area 112. The second lens 123 is used to collimate and expand the light beam from the second light-transmitting area 112 before outputting it. Thus, even if dust exists on the surface of the second lens 123 away from the second light-transmitting area 112, the influence of the dust on the light beam can be reduced because the second lens 123 expands the size of the light beam spot.

[0142] For example, the first lens 121 and the insert 110 are connected by an adhesive layer. The second lens 123 and the insert 110 are connected by an adhesive layer.

[0143] As described above, in the embodiment where the vertical projection of the first light-transmitting area 111 in the light-transmitting area group 001 onto the second surface 102 overlaps with the second light-transmitting area 112 in the same light-transmitting area group 001, the first lens 121 and the second lens 123, respectively covering the first light-transmitting area 111 and the second light-transmitting area 112 in the same light-transmitting area group 001, are obviously arranged opposite to each other. When the optical connector male connector 100 and the optical connector female connector are in the connected state, the forces exerted by the optical connector female connector on the first lens 121 and the second lens 123 are in opposite directions and similar in magnitude. This is beneficial for the optical connector male connector 100 to receive uniform force, thereby improving the reliability of the optical connector male connector 100.

[0144] For example, the materials of the first lens 121 and the second lens 123 include light-transmitting materials. For example, the light-transmitting material includes silica, polymethyl methacrylate (PMMA), polycarbonate (PC), polystyrene (PS), thermoplastic polyurethanes (TPU), or fluoroplastics, etc.

[0145] In the embodiments of this application, the first lens 121 and the second lens 123 are not necessary, and the male optical connector 100 may not include the first lens 121 and the second lens 123.

[0146] Figure 2b and Figure 3b In the example, the transmission medium of the light beam is uniform during the transmission of the light beam from the first optical waveguide 120 to the first transparent region 111. In some embodiments, other optical transmission media may be disposed between the first optical waveguide 120 and the first transparent region 111.

[0147] Figure 4 This is a cross-sectional schematic diagram of a male optical connector 100 provided in an embodiment of this application. Figure 4 In the example, the ferrule 110 is provided with a plurality of light-transmitting holes, each light-transmitting hole having an opening on a first surface 101, and a first light-transmitting area 111 located within the opening. The optical connector male 100 also includes a reflective element located within the ferrule 110; the reflective element is used to reflect a light beam from the first optical waveguide 120 to the light-transmitting hole, and the light-transmitting hole is used to allow the light beam from the reflective element to exit from the first light-transmitting area 111.

[0148] For ease of distinction, the light-transmitting aperture for the beam transmitted through the first optical waveguide 120 is defined as the first light-transmitting aperture 122. The reflecting element for the beam reflected from the first optical waveguide 120 is defined as the first reflecting element 131. The light-transmitting aperture for the beam transmitted through the second optical waveguide 130 is defined as the second light-transmitting aperture 132. The reflecting element for the beam reflected from the second optical waveguide 130 is defined as the second reflecting element 133.

[0149] The insert 110 is provided with a plurality of first light-transmitting holes 122, each first light-transmitting hole 122 having an opening on the first surface 101, and a first light-transmitting area 111 located within the opening of the first light-transmitting hole 122. A plurality of first reflective elements 131 are provided inside the insert 110. The plurality of first reflective elements 131, the plurality of first optical waveguides 120, the plurality of first light-transmitting holes 122, and the plurality of first light-transmitting areas 111 correspond one-to-one.

[0150] The first reflective element 131 reflects the light beam from the first optical waveguide 120 to the first light-transmitting aperture 122, and the first light-transmitting aperture 122 emits the light beam from the first reflective element 131 out of the first light-transmitting area 111.

[0151] Similarly, the ferrule 110 is provided with a plurality of second light-transmitting holes 132, each second light-transmitting hole 132 having an opening on the second surface 102, and a second light-transmitting area 112 located within the opening of the second light-transmitting hole 132. A plurality of second reflective elements 133 are provided inside the ferrule 110. The plurality of second reflective elements 133, the plurality of second optical waveguides 130, the plurality of second light-transmitting holes 132, and the plurality of second light-transmitting areas 112 correspond one-to-one.

[0152] The second reflective element 133 reflects the light beam from the second optical waveguide 130 to the second light-transmitting aperture 132, and the second light-transmitting aperture 132 emits the light beam from the second reflective element 133 out of the second light-transmitting area 112.

[0153] For example, both the first reflecting element 131 and the second reflecting element 133 are reflectors.

[0154] The embodiments of this application do not limit the angle at which the first reflective element 131 folds the light path. For example, the angle at which the first reflective element 131 folds the light path is 70°-100°. For example, the angle at which the first reflective element 131 folds the light path is 70°, 80°, 85°, 90°, 95° or 100°. The angle at which the second reflective element 133 folds the light path is similar, and will not be described again here.

[0155] Thus, the first optical waveguide 120 and the second optical waveguide 130 do not need to be bent within the ferrule 110. Under the action of the aforementioned reflective element and light-transmitting aperture, the light beams from the first optical waveguide 120 and the second optical waveguide 130 can also be transmitted to the outer peripheral surface of the ferrule 110.

[0156] In some embodiments of this application, the filling medium in the first light-transmitting hole 122 and the second light-transmitting hole 132 can be air or the like. In some embodiments of this application, the filling medium in the first light-transmitting hole 122 and the second light-transmitting hole 132 can be light-transmitting materials such as silica, polymethyl methacrylate, polycarbonate, polystyrene, thermoplastic polyurethane elastomer rubber, fluoroplastics, or liquid matching liquid. Figure 4 In the example, the male connector 100 of the optical connector can also be configured as described above. Figure 2b The first lens 121 and the second lens 123 are shown. Figure 4 For the remaining structures, please refer to the foregoing. Figure 2b The description in the text. It is understandable that the aforementioned... Figure 3a The male connector 100 in the middle can also be set. Figure 4 The first light-transmitting hole 122, the first reflective element 131, the second reflective element 133, and the second light-transmitting hole 132 are shown in the figure.

[0157] In some embodiments of this application, to reduce the assembly difficulty of the male optical connector 100 and the female optical connector, structures such as marking portions and stop portions can be provided on the male optical connector 100. The following description... Figure 5 An exemplary description is provided.

[0158] Figure 5 This is a schematic diagram of another optical connector male head 100 provided in an embodiment of this application. Please refer to... Figure 5 The male optical connector 100 also includes a marking portion 140, which is disposed on the ferrule 110 and is used to indicate the position of one of the plurality of first light-transmitting areas 111.

[0159] Thus, during the assembly process of the male optical connector 100 and the female optical connector, the position of the first light-transmitting area 111 marked by the marking section 140 can be quickly identified by the marking section 140. This helps to reduce assembly time.

[0160] The structure of the identification part 140 is not limited in this application embodiment. It can be configured according to the main body of the identification part 140. In some embodiments, if the main body of the identification part 140 is a camera or a barcode scanner, then the identification part 140 can be a QR code, a patterned coating, or other structures.

[0161] In some embodiments, if the main body of the identification part 140 is a human eye, then the identification part 140 may be a patterned coating, a groove or a protrusion, or a coating with a color different from that of the insert 110.

[0162] The pattern of the identification part 140 is not limited in this embodiment. Figure 5 In the example, the pattern of the identifier 140 is "①".

[0163] In some embodiments of this application, there may be multiple marking units 140, with each marking unit 140 indicating the position of a first light-transmitting area 111. This facilitates the identification of the position of each first light-transmitting area 111.

[0164] In some embodiments of this application, the insert 110 may also be provided with a marking portion for indicating the position of the second light-transmitting area 112. Please refer to the foregoing description of the marking portion for indicating the position of the first light-transmitting area 111, which will not be repeated here.

[0165] Figure 5In some embodiments of this application, the male optical connector 100 further includes a stop portion 150, which protrudes from the first surface 101. The first light-transmitting area 111 is closer to the free end of the ferrule 110 than the stop portion 150. In other words, the stop portion 150 does not cover the first light-transmitting area 111, and the stop portion 150 will not interfere with the optical path of the light beam emitted from the first light-transmitting area 111.

[0166] Because the first light-transmitting area 111 is closer to the free end of the ferrule 110 than the stop portion 150, during the assembly of the male and female optical connectors, the free end of the ferrule 110 extends into the female optical connector. When the stop portion 150 and the female optical connector come into contact, the ferrule 110 and the female optical connector are successfully mated. Thus, the stop portion 150 can indicate whether the ferrule 110 is assembled in the correct position, simplifying the assembly process.

[0167] In some embodiments of this application, when the stop portion 150 abuts against the optical connector female head, the assembly error between the optical connector male head 100 and the optical connector female head is less than or equal to 10 μm. The interaction force between the optical connector male head 100 and the optical connector female head is less than or equal to 5 N (Newtons).

[0168] The structure of the stop portion 150 is not limited in this embodiment. For example, the stop portion 150 can be a triangular prism structure. The free end of the stop portion 150 near the ferrule 110 has a contact surface, which abuts against the optical connector female head when the stop portion 150 abuts against the optical connector female head. In other embodiments, the stop portion 150 can have other structures, as long as it can abut against the optical connector female head.

[0169] In some embodiments of this application, the stop portion 150 and the insert 110 are connected as a single molded part. In some embodiments of this application, the stop portion 150 and the insert 110 are connected by an adhesive layer, a solder layer, or a snap-fit ​​connection.

[0170] Figure 5 In the example, the stop portion 150 is disposed on the first surface 101. In some embodiments, the stop portion 150 may be disposed on the second surface 102, or on other surfaces of the outer peripheral surface of the insert 110. Alternatively, in some embodiments, the stop portion 150 may be disposed on both the first surface 101 and the second surface 102.

[0171] Figure 2a , Figure 3a and Figure 4 The male connector 100 shown can also be configured. Figure 5 The stop portion 150 and the marking portion 140 are shown.

[0172] In some embodiments, the stop portion 150 is not necessary, and the male end of the optical connector male connector 100 can be connected to the housing 14 (e.g., Figure 1b (As shown) Indicates whether the insert 110 is installed in the correct position.

[0173] In some embodiments of this application, the insert 110 is not limited to the aforementioned shape.

[0174] Figure 6 This is a schematic diagram of the structure of a ferrule 110, a first optical waveguide 120, and a second optical waveguide 130 provided in an embodiment of this application. Figure 6 and Figure 2a The differences include: the structure of the ferrule 110 is different. Figure 6 In the example, the ferrule 110 includes a connecting shell 113 and a plurality of embedded portions 114. One embedded portion 114 surrounds the outer peripheral surface of a first optical waveguide 120 and the outer peripheral surface of a second optical waveguide 130. Each embedded portion 114 has a first light-transmitting area 111 and a second light-transmitting area 112. There is a gap between adjacent embedded portions 114, and all embedded portions 114 are connected to the connecting shell 113.

[0175] Figure 6 In the example, multiple embedding portions 114 have the same size and shape. The multiple embedding portions 114 share a common surface on one side, which is a first surface 101, and the multiple embedding portions 114 share a common surface on the other side, which is a second surface 102.

[0176] Because there are gaps between the multiple embedded portions 114, the weight of the ferrule 110 can be reduced. Furthermore, during the fabrication of the optical connector male 100, a first optical waveguide 120 and a second optical waveguide 130 can be connected to an embedded portion 114, and then multiple embedded portions 114 can be connected to the connecting shell 113 to assemble the optical connector male 100. The connecting shell 113 and the embedded portions 114 can be assembled according to the required number of first optical waveguides 120 in the optical connector male 100. For example, the embedded portions 114, the first optical waveguide 120, and the second optical waveguide 130 are connected to form a preform, and the number of preforms is set according to the required number of first optical waveguides 120 and second optical waveguides 130.

[0177] In some embodiments of this application, an embedding portion 114 is provided with a plurality of first light-transmitting areas 111 and a plurality of second light-transmitting areas 112.

[0178] In some embodiments, the embedded portion 114 is formed outside the first optical waveguide 120 and the second optical waveguide 130 by injection molding.

[0179] For example, the connecting shell 113 and the embedded part 114 can be connected by an adhesive layer or a solder layer.

[0180] The structure of the connecting shell 113 is not limited in this application embodiment. For example, the connecting shell 113 can be an adhesive layer, and multiple embedded parts 114 are connected through the adhesive layer. Alternatively, the connecting shell 113 can be a frame-shaped bracket, and multiple embedded parts 114 are all connected to the frame-shaped bracket.

[0181] Figure 3a , Figure 4 and Figure 5 The structure of the ferrule 110 in the example can be as follows: Figure 6 As shown.

[0182] In some embodiments of this application, a light beam transmitted by a first optical waveguide 120 and a light beam transmitted by a second optical waveguide 130 may originate from the same light beam. In other words, after a light beam is split, part of it is transmitted through a first optical waveguide 120 and exits through a first light-transmitting area 111, while the other part is transmitted through a second optical waveguide 130 and exits through a second light-transmitting area 112. Thus, the light beam transmitted by the first optical waveguide 120 and the light beam transmitted by the second optical waveguide 130 can serve as backups for each other. Even if part of the light beam is damaged or blocked by dust, the other part of the light beam can continue to transmit the information in the beam, further reducing the impact of dust on the male connector 100.

[0183] For example, a light beam transmitted through a first optical waveguide 120 and a light beam transmitted through a second optical waveguide 130 both originate from the same third optical waveguide.

[0184] Figure 7 This is a schematic diagram of the structure of an optical connector male 100 including a third optical waveguide 160, provided for an embodiment of this application. Please refer to... Figure 7 The male optical connector 100 may also include multiple third optical waveguides 160. The number of third optical waveguides 160, first optical waveguides 120, and second optical waveguides 130 are all the same.

[0185] A light beam transmitted through a first optical waveguide 120 and a light beam transmitted through a second optical waveguide 130 both originate from the same third optical waveguide 160. Both the first optical waveguide 120 and the second optical waveguide 130 are connected to the third optical waveguide 160. The ends of the first optical waveguide 120 and the second optical waveguide 130 located away from the second light-transmitting region 112 are both connected to the ends of the third optical waveguide 160. The first optical waveguide 120 is used to transmit a portion of the light beam from the third optical waveguide 160, and the second optical waveguide 130 is used to transmit another portion of the light beam from the same third optical waveguide 160.

[0186] Thus, if one of the first optical waveguides 120 and the second optical waveguide 130 connected to the same third optical waveguide 160 is contaminated with dust, the light beam within the third optical waveguide 160 can be transmitted from the other uncontaminated optical waveguide. Only when the light beams output from both the first optical waveguide 120 and the second optical waveguide 130 connected to the same third optical waveguide 160 are simultaneously contaminated with dust will the light beam transmitted within that third optical waveguide 160 fail. This reduces the probability of optical signal failure, improves the dust tolerance of the optical connector male 100, and enhances reliability.

[0187] The structure, materials, and dimensions of the third optical waveguide 160 are described in the preceding description of the first optical waveguide 120. They will not be repeated here.

[0188] One end of the fiber core of the second optical waveguide 130 and the fiber core of the first optical waveguide 120 are connected to the fiber core of the third optical waveguide 160.

[0189] In ferrule 110 Figure 6 In the structure shown, one embedding portion 114 can embed one first optical waveguide 120, one second optical waveguide 130, and one third optical waveguide 160. Alternatively, one embedding portion 114 can embed multiple first optical waveguides 120, the same number of second optical waveguides 130 as the first optical waveguides 120, and the same number of third optical waveguides 160 as the first optical waveguides 120. In one embedding portion 114, the first optical waveguides 120, second optical waveguides 130, and third optical waveguides 160 correspond one-to-one.

[0190] This application does not limit the connection method of the first optical waveguide 120 and the third optical waveguide 160. Exemplarily, the first optical waveguide 120 and the third optical waveguide 160 are connected as a single molded part. Exemplarily, both the first optical waveguide 120 and the third optical waveguide 160 are formed by an etching process. Alternatively, the first optical waveguide 120 and the third optical waveguide 160 are formed by a tapered process. The connection method of the second optical waveguide 130 and the third optical waveguide 160 is similar.

[0191] This application embodiment does not limit the ratio of the light beam transmitted from the third optical waveguide 160 to the first optical waveguide 120 and the light beam transmitted to the second optical waveguide 130. In other words, this application embodiment does not limit the ratio of the energy of the light beams transmitted from the third optical waveguide 160 to the first optical waveguide 120 and the second optical waveguide 130. In some embodiments, the aforementioned energy ratio can be 1:1, 1:2, 1:3, 4:6, 1:4, or 1:5, etc.

[0192] In some scenarios, by observing the probability of contamination of the beam output from the first optical waveguide 120 and the probability of contamination of the beam output from the second optical waveguide 130, a smaller amount of energy can be allocated to the beam with a higher probability of contamination.

[0193] For example, if the beam output from the first optical waveguide 120 has a higher probability of being contaminated than the beam output from the first optical waveguide 120, then the energy of the beam output from the first optical waveguide 120 is less than the energy of the beam output from the first optical waveguide 120.

[0194] For example, in an embodiment where the first optical waveguide 120, the second optical waveguide 130, and the third optical waveguide 160 are integrated optical waveguides, the beam output from the first optical waveguide 120 and the energy ratio of the beam output from the first optical waveguide 120 can be adjusted by setting the width, length, curvature, and branching angle of the first optical waveguide 120 and the second optical waveguide 130.

[0195] For example, in an embodiment where the first optical waveguide 120, the second optical waveguide 130, and the third optical waveguide 160 are circular optical waveguides, during the process of fabricating the branch unit by fused taper, the radius of the second optical waveguide 130 and the radius of the first optical waveguide 120 can be adjusted by controlling the angle of optical fiber twist, the length of stretching, and the degree of melting, so as to adjust the beam output from the first optical waveguide 120 and the energy ratio of the beam output from the first optical waveguide 120.

[0196] In an embodiment where the ferrule 110 includes a group of light-transmitting areas 001, the light beam transmitted through the first light-transmitting area 111 and the second light-transmitting area 112 of the group of light-transmitting areas 001 originates from a third optical waveguide 160.

[0197] In some embodiments of this application, the third optical waveguide 160 extends into the ferrule 110. In other words, the ferrule 110 also surrounds at least a portion of the outer peripheral surface of the third optical waveguide 160. In some embodiments, the third optical waveguide 160 is located outside the ferrule 110.

[0198] In some embodiments of this application, in order to reduce the loss caused by interference during the beam combining process of light beams transmitted through the same third optical waveguide 160 and output from the first transparent area 111 and the second transparent area 112, the optical connector male 100 may also include a polarization converter in some embodiments.

[0199] Figure 8a This is a schematic diagram of the structure of a male optical connector 100, including a first polarization converter 170 and a second polarization converter 180, provided for embodiments of this application. Please refer to... Figure 8a The optical connector male 100 further includes a first polarization converter 170 and a second polarization converter 180. The first polarization converter 170 is used to convert the light beam from the first light-transmitting area 111 into a first polarized light output. The second polarization converter 180 is used to convert the light beam output from the second light-transmitting area 112 into a second polarized light output, wherein the polarization direction of the first polarized light and the polarization direction of the second polarized light are not parallel.

[0200] When the polarization directions of the two beams are not parallel, the loss caused by interference during beam combining can be effectively overcome. Since the polarization directions of the first and second polarized beams are not parallel, the loss caused by interference during beam combining of beams transmitted through the same third optical waveguide 160 from the first and second waveguides can be effectively overcome. For example, a loss of 3 dB can be saved.

[0201] For example, the aforementioned transmission is carried out by the same third optical waveguide 160: the beams emitted from the first optical waveguide and the beams emitted from the second optical waveguide can be combined in the optical connector female.

[0202] For example, the angle between the polarization direction of the first polarized light and the polarization direction of the second polarized light can be 5°-175°. For instance, the angle between the polarization direction of the first polarized light and the polarization direction of the second polarized light can be 5°, 10°, 15°, 30°, 40°, 45°, 60°, 90°, 100°, 120°, 130°, 150°, 160°, 170°, or 180°, etc.

[0203] In some embodiments of this application, the polarization direction of the first polarized light is perpendicular to the polarization direction of the second polarized light. This overcomes the loss caused by interference during beam combining of the second and third optical waveguides within the same branch unit, thus optimizing the performance of the optical connector.

[0204] In some embodiments, the first polarization converter 170 can be a transverse electromagnetic wave converter, and the polarization state of the first polarized light is TE polarization state. The second polarization converter 180 can be a transverse magnetic wave converter, and the polarization state of the second polarized light is TM polarization state.

[0205] Transverse electric waves (TE waves) are electromagnetic wave modes in which there is no electric field component in the direction of propagation, while the magnetic field component is non-zero in that direction. In this mode, the electric field vector is perpendicular to the plane containing both the propagation direction and the magnetic field vector.

[0206] The electric field vector of the TE polarization state lies in a plane perpendicular to the propagation direction and its direction remains fixed. It is a linear polarization state, and its electric field intensity distribution and magnetic field intensity distribution are perpendicular to each other. In structures such as waveguides, the cutoff frequency and propagation characteristics of the TE mode are closely related to factors such as the size and shape of the waveguide and the medium it is filled with.

[0207] Transverse magnetic waves (TE waves) are electromagnetic wave modes in which there is no magnetic field component in the direction of propagation, while the electric field component is non-zero in that direction. In this case, the magnetic field vector is perpendicular to both the plane containing the propagation direction and the plane containing the electric field vector.

[0208] The magnetic field vector of the TM polarization state lies in a plane perpendicular to the propagation direction and its direction remains fixed. It is also a linear polarization state. In optical devices such as optical thin films and optical fibers, light in the TM polarization state and light in the TE polarization state may exhibit different reflection, refraction and transmission characteristics. This allows for the separation and modulation of the TE and TM polarization states by designing specific optical structures.

[0209] The male optical connector 100 includes a first lens 121 (e.g., ...). Figure 7 (as shown) and the second lens 123 (as shown) Figure 7 In the embodiment shown, the first polarization converter 170 is located on the side of the first lens 121 opposite to the first light-transmitting area 111, meaning that the light beam output from the first light-transmitting area 111 first passes through the first lens 121 before being transmitted to the first polarization converter 170. Similarly, the second polarization converter 180 is located on the side of the second lens 123 opposite to the second light-transmitting area 112, meaning that the light beam output from the second light-transmitting area 112 first passes through the second lens 123 before being transmitted to the second polarization converter 180.

[0210] In some embodiments of this application, the male optical connector 100 includes a first polarization converter 170. A beam of light from a first light-transmitting area 111 is converted into a beam of first polarized light by the first polarization converter 170 and output. In other words, multiple first light-transmitting areas 111 share one first polarization converter 170. Thus, the number of first polarization converters 170 is reduced, which can save on the cost of the male optical connector 100.

[0211] In some embodiments of this application, the male optical connector 100 includes a plurality of first polarization converters 170. Each first polarization converter 170 corresponds to a first light-transmitting area 111. The light beam from one first light-transmitting area 111 is converted into a first polarized light output by one first polarization converter 170. Alternatively, two or more first light-transmitting areas 111 correspond to one first polarization converter 170. The light beams output from two or more first light-transmitting areas 111 are converted into first polarized light output by one first polarization converter 170.

[0212] The number of second polarization converters 180 in the male optical connector 100 is similar and will not be repeated here.

[0213] In some embodiments of this application, the first polarization converter 170 and the second polarization converter 180 are not necessary, and the male optical connector 100 may not have the first polarization converter 170 and the second polarization converter 180. For example, providing the first polarization converter 170 and the second polarization converter 180 at the female optical connector can also reduce beam loss. Alternatively, providing the first polarization converter 170 and the second polarization converter 180 at a location other than the female and male optical connectors in the optical link can also reduce beam loss.

[0214] In some embodiments of this application, both the first polarization converter 170 and the second polarization converter 180 are located within the ferrule 110. This increases the integration density of the optical connector male 100 and reduces its size. It also prevents dust and other contaminants from polluting the first polarization converter 170 and the second polarization converter 180.

[0215] In some embodiments of this application, both the first polarization converter 170 and the second polarization converter 180 are located outside the ferrule 110. The first polarization converter 170 is used to convert a light beam from the first optical waveguide 120 into first polarized light and output it to the first light-transmitting region 111. The second polarization converter 180 is used to convert a light beam from the second optical waveguide 130 into second polarized light and output it to the second light-transmitting region 112. The polarization directions of the first polarized light and the second polarized light are not parallel. This facilitates the assembly of the first polarization converter 170 and the second polarization converter 180.

[0216] In some embodiments of this application, the beam output from the third optical waveguide 160 can be polarized and split, so that the polarization directions of the beams emitted from the first optical waveguide 120 and the second optical waveguide 130 are not parallel. This can also overcome the loss caused by interference during the beam combining process of the beams emitted from the second and third optical waveguides in the same branch unit. This can optimize the performance of the optical connector. For example, a polarization beam splitter can be used to split the beam output from the third optical waveguide.

[0217] Figure 8b This is a schematic diagram of the structure of the male optical connector 100, which includes a polarization beam splitter 401, provided in an embodiment of this application. Figure 8b In this example, the male optical connector 100 further includes multiple polarization beamsplitters 401. Each polarization beamsplitter 401 is connected to a third optical waveguide 160 in a one-to-one correspondence. The number of polarization beamsplitters 401 and the third optical waveguide 160 is the same. The polarization beamsplitters 401 are used to split a beam from the third optical waveguide 160 into third polarized light and fourth polarized light. A first optical waveguide 120 is used to transmit the third polarized light; a second optical waveguide 130 is used to transmit the fourth polarized light; the polarization directions of the third polarized light and the fourth polarized light are not parallel.

[0218] Since the polarization directions of the third polarized light and the fourth polarized light are not parallel, the loss caused by interference during the beam combining process of the beam emitted from the first optical waveguide 120 and the beam emitted from the second optical waveguide 130 is effectively overcome. In some embodiments, the polarization directions of the third polarized light and the fourth polarized light are perpendicular to each other.

[0219] In an embodiment where the third optical waveguide 160 is an integrated optical waveguide, the polarization beam splitter 401 can be formed in the third optical waveguide 160 by an etching process.

[0220] In an embodiment where the third optical waveguide 160 is a circular optical waveguide, the polarization beam splitter 401 is connected to the third optical waveguide 160.

[0221] In embodiments where the signal light transmitted through the male connector 100 is multimode signal light, a mode converter can be used instead of the aforementioned polarization converter. In other words, in embodiments where the beam transmitted in the third optical waveguide 160 is multimode light, the aforementioned first and second polarization converters can be replaced by a mode converter.

[0222] Figure 9 This is a schematic diagram of the structure of a male optical connector 100, including a first mode converter 021 and a second mode converter 022, provided for embodiments of this application. Please refer to... Figure 9 In the embodiment where the third optical waveguide 160 transmits multimode light, the male optical connector 100 may further include a first mode converter 021 and a second mode converter 022. The first mode converter 021 is used to convert the light beam from the first light-transmitting area 111 into a first multimode signal light output.

[0223] The second mode converter 022 is used to convert the light beam from the second light-transmitting area 112 into a second multimode signal light output; the modes in the first multimode signal light and the modes in the second multimode signal light are different.

[0224] Since the modes in the first multimode signal light and the modes in the second multimode signal light are different, the loss caused by interference during the beam combining process of the beams emitted from the first and second optical wavesguides, which are transmitted by the same third optical waveguide, is effectively improved, and the loss of the beam passing through the male connector 100 is reduced.

[0225] For example, the first multimode signal light includes multimode signal light of mode 1 and mode 2. The second multimode signal light includes multimode signal light of mode 3 and mode 4. It is understood that the multimode signal light in the first multimode signal light can have one, two, or more modes. The multimode signal light in the second multimode signal light can have one, two, or more modes.

[0226] In some embodiments of this application, both the first mode converter 021 and the second mode converter 022 are located within the ferrule 110. This increases the integration density of the optical connector male 100 and reduces its size. It also prevents dust and other contaminants from polluting the first mode converter 021 and the second mode converter 022.

[0227] In some embodiments of this application, both the first mode converter 021 and the second mode converter 022 are located outside the ferrule 110. This facilitates the assembly of the first mode converter 021 and the second mode converter 022.

[0228] The embodiments of this application do not limit the number of modes in the first multimode signal light, nor do the embodiments of this application limit the number of modes in the second multimode signal light.

[0229] and Figure 8a Similarly, the number of first polarization converters 170 in the example is the same, and the number of first mode converters 021 can be one or more. Multiple first light-transmitting regions 111 share one first mode converter 021. Alternatively, one first light-transmitting region 111 shares one first mode converter 021. Or, two or more first light-transmitting regions 111 share one first mode converter 021. The relationship between the number of second mode converters 022 and second light-transmitting regions 112 is similar and will not be repeated here.

[0230] In the aforementioned example, the light-transmitting area of ​​the insert 110 is distributed on the first surface 101 and the second surface 102 of the insert 110. In some embodiments of this application, the light-transmitting area of ​​the insert 110 may be distributed on more surfaces of the insert 110.

[0231] Figure 10 This is a schematic diagram of the structure of another optical connector male head 100 provided in an embodiment of this application. Figure 10 and Figure 2a The differences include: the insert 110 has a light-transmitting area on the surface other than the first surface 101 and the second surface 102.

[0232] Figure 10 In the process, the outer peripheral surface of the ferrule 110 also includes a third surface 103, which is located between the first surface 101 and the second surface 102. The third surface 103 is provided with a plurality of third light-transmitting areas 024, and the optical connector male 100 may also include a plurality of fourth optical waveguides (…). Figure 10 (Not shown in the image), the ferrule 110 surrounds the outer peripheral surface of each fourth optical waveguide. A third light-transmitting area 024 is used to emit a beam of light from a fourth optical waveguide.

[0233] Since the third light-transmitting area 024 is located on the outer peripheral surface of the ferrule 110, during the connection process between the male and female optical connectors, if dust is present in the environment, it will accumulate more on the end face of the ferrule 110 due to capillary effect. Therefore, the probability of dust adhering to the third light-transmitting area 024 is relatively low. This reduces the impact of dust on the beam transmitted within the male optical connector 100, which helps improve the dust holding capacity of the male optical connector 100 and enhances its reliability.

[0234] The positional relationship between the third light-transmitting region 024 and the third surface 103 is described in the preceding description of the first light-transmitting region 111 and the first surface 101. The number of third light-transmitting regions 024 is described in the preceding description of the first light-transmitting region 111. The relationship between the third light-transmitting region 024 and the fourth optical waveguide is described in the preceding description of the first light-transmitting region 111 and the first optical waveguide 120.

[0235] In some embodiments of this application, the outer peripheral surface of the ferrule 110 further includes a fourth surface 104, which is located between the first surface 101 and the second surface 102. The third surface 103 and the fourth surface 104 are disposed opposite to each other. The fourth surface 104 is provided with a plurality of fourth light-transmitting areas 026. The optical connector male 100 may also include a plurality of fifth optical waveguides. Figure 10 (Not shown in the image), the ferrule 110 surrounds the outer peripheral surface of each fifth optical waveguide. A fourth light-transmitting zone 026 is used to emit a beam of light from a fifth optical waveguide.

[0236] Similarly, if dust is present in the environment, the probability of dust adhering to the fourth light-transmitting area 026 is relatively small. This reduces the impact of dust on the light beam transmitted within the male connector 100.

[0237] The positional relationship between the fourth light-transmitting region 026 and the fourth surface 104 is described in the preceding description of the first light-transmitting region 111 and the first surface 101. The number of fourth light-transmitting regions 026 is described in the preceding description of the first light-transmitting region 111. The relationship between the fourth light-transmitting region 026 and the fifth optical waveguide is described in the preceding description of the first light-transmitting region 111 and the first optical waveguide 120.

[0238] It is understood that the optical connector male 100 in the other examples mentioned above may also include... Figure 10 The fourth light-transmitting region 026 and the fifth optical waveguide, the third light-transmitting region 024 and the fourth optical waveguide are shown in the figure.

[0239] In some embodiments of this application, the male optical connector 100 may also include a fiber array (FA).

[0240] Figure 11 This is a schematic diagram of the structure of another optical connector male head 100 provided in an embodiment of this application. Figure 11 and Figure 8a The differences include: the male optical connector 100 can also include an optical fiber array.

[0241] Figure 11 In this optical connector, the male connector 100 includes two fiber arrays FA. One fiber array FA is used to transmit a light beam from a first transparent region 111. Exemplarily, one fiber in the fiber array FA corresponds to one first transparent region 111, used to transmit a light beam emitted from one of the first transparent regions 111. The other fiber array FA is used to transmit a light beam from a second transparent region 112. One fiber in the fiber array FA corresponds to one second transparent region 112, used to transmit a light beam from one of the second transparent regions 112.

[0242] The foregoing described some examples of the male optical connector 100 in the embodiments of this application. The embodiments of this application also provide a female optical connector, which can similarly reduce the impact of dust on the female optical connector and improve its performance.

[0243] Figure 12a This is a schematic diagram of the structure of an optical connector female head 200 provided in an embodiment of this application. Figure 12b for Figure 12a A cross-sectional view of CC. Please refer to [link / reference]. Figure 12b The optical connector female 200 includes a ferrule 210, a plurality of first optical waveguides 220, and a plurality of second optical waveguides 230. One end of the ferrule 210 is provided with a receiving groove 300. The receiving groove 300 has an inner peripheral wall and a bottom wall. The bottom wall of the receiving groove 300 and the opening of the receiving groove 300 are opposite to each other, and the inner peripheral wall of the receiving groove 300 is located between the bottom wall and the opening of the receiving groove 300.

[0244] The inner peripheral wall of the receiving groove 300 includes a first inner peripheral wall 301 and a second inner peripheral wall 302 disposed opposite to each other. The first inner peripheral wall 301 is provided with a plurality of first light-transmitting areas 211. The second inner peripheral wall 302 is provided with a plurality of second light-transmitting areas 212.

[0245] A ferrule 210 surrounds the outer peripheral surface of each first optical waveguide 220, and a first light-transmitting area 211 is used to emit a light beam from a first optical waveguide 220. A ferrule 210 surrounds the outer peripheral surface of each second optical waveguide 230, and a second light-transmitting area 212 is used to emit a light beam from a second optical waveguide 230.

[0246] Similar to the aforementioned male optical connector, if dust is present in the environment, it will accumulate more on the bottom wall of the receiving groove 300 due to capillary effect. In the embodiments of this application, the first light-transmitting area 111 and the second light-transmitting area 112 are both located on the first inner peripheral wall 301 and the second inner peripheral wall 302 of the ferrule 110. Therefore, the probability of dust adhering to the first light-transmitting area 211 and the second light-transmitting area 212 is relatively small. This reduces the impact of dust on the light beam transmitted within the female optical connector 200. In addition, the inner peripheral wall of the receiving groove 300 is easier to clean than the bottom wall, which can reduce dust accumulation. Reducing the impact of dust improves the dust holding capacity of the female optical connector 200 and enhances its reliability.

[0247] Figure 12b In the example, the receiving slot 300 is a square slot. In some embodiments, the receiving slot 300 can be other shapes. The shape depends on the shape of the male optical connector to which the receiving slot 300 is connected.

[0248] In the embodiments of this application, the description of the first light-transmitting area 211 and the second light-transmitting area 212 is the same as the description of the first light-transmitting area 111 and the second light-transmitting area 112 in the aforementioned optical connector male head 100.

[0249] Figure 12c This is a schematic cross-sectional view of an optical connector female head 200 provided in an embodiment of this application.
