Description

Technical Field

[0001] This application relates to the field of optical transmission technology, and in particular to an optical fiber connector, an optical transmission component, and an optical communication device. Background Technology

[0002] Optical transmission, with its unique characteristics such as ultra-high bandwidth and low electromagnetic interference, is gradually becoming the mainstream solution for modern communication. In particular, newly built networks, such as access networks represented by fiber-to-the-home (FTTH), are being deployed on a large scale.

[0003] Among them, optical communication networks used in access network scenarios mainly exist in the form of passive optical networks (PON). With the overall situation of the widespread adoption of optical networks, the deployment of a large number of PON networks requires a similarly large number of communication devices. Related communication devices, such as optical line terminals (OLTs), mainly consist of optical modules and single boards and chassis that house the optical modules.

[0004] The structural performance of each communication device directly impacts the performance of the entire optical network. For example, messy wiring within communication devices directly affects the space they occupy. Therefore, simplifying the wiring is a pressing technical problem that needs to be solved. Utility Model Content

[0005] This application provides a fiber optic connector, an optical transmission component, and an optical communication device, designed to improve the simplicity of cabling.

[0006] To achieve the above objectives, this application adopts the following technical solution.

[0007] In a first aspect, this application provides an optical transmission component. The optical transmission component includes a first optical connector, a second optical connector, and a multiplexer. The second optical connector includes a first connector and a second connector connected to each other; the multiplexer is used to combine a first light beam from the first optical connector and a second light beam from the first connector of the second optical connector, and output a third light beam through the second connector of the second optical connector.

[0008] Thus, the transmission paths of both the second and third beams include the path from the location of the second optical connector to the location of the multiplexer. The transmission paths of the second and third beams are very close. This results in a simpler wiring configuration for the optical transmission components, improving deployment efficiency. The optical transmission components require less cabling space, which facilitates more compact network equipment and reduces the space occupied by the network devices. Furthermore, the second optical connector comprises two interconnecting joints that are relatively compact. Compared to the first and second joints being located in separate fiber optic connectors, the space required to install the first and second joints is smaller, further reducing the space occupied by the optical transmission components.

[0009] In conjunction with the first aspect, in some feasible ways, the multiplexer is fixedly connected to the first optical connector. This results in a more compact connection between the multiplexer and the first optical connector.

[0010] In conjunction with the first aspect, in some feasible ways, the multiplexer is fixed to the first connector, or the multiplexer is fixed to the second connector. In this way, the multiplexer connects to the second optical connector. The multiplexer and the second optical connector are more compact.

[0011] In conjunction with the first aspect, in some feasible embodiments, the optical transmission assembly further includes a first optical fiber and a second optical fiber, the first connector being connected to the multiplexer via the first optical fiber, and the second connector being connected to the multiplexer via the second optical fiber.

[0012] Thus, the second and first optical fibers share the space between the second optical connector and the multiplexer. The extension paths of the second and first optical fibers can be the same or very close. Compared to having different extension paths for the second and first optical fibers, the wiring of the optical transmission components is simpler, and the wiring space required for the optical transmission components is smaller. This is beneficial for making network equipment that includes optical transmission components more compact and reducing the space occupied by network equipment.

[0013] In conjunction with the first aspect, in some feasible embodiments, the second optical connector further includes wire teeth that connect to the second connector, forming a channel with the second connector, and the second optical fiber and the first optical fiber passing through the channel. Alternatively, the wire teeth connect to the first connector, forming a channel with the first connector, and the second optical fiber and the first optical fiber passing through the channel.

[0014] In this way, the wire teeth can constrain the relative positions of the first optical fiber, the second optical fiber, and the second optical connector. This prevents the first and second optical fibers from being too far off from the second optical connector, resulting in cleaner cabling.

[0015] In conjunction with the first aspect, in some feasible ways, the outer surface of the second connector includes an arcuate surface to which both the first and second optical fibers are abutted.

[0016] In this way, the curved surface can constrain the paths of the first and second optical fibers extending on the outer surface of the second connector to be curved. This makes the bending radii of the first and second optical fibers close to the radius of the curved surface. The curved surface constrains the minimum bending radius of the first and second optical fibers, avoiding signal loss within the optical fibers due to the first and second optical fibers being too small during assembly.

[0017] In conjunction with the first aspect, in some feasible ways, both the second optical fiber and the first optical fiber are bonded to the arcuate surface.

[0018] This prevents the first and second optical fibers from sliding on the curved surface, which helps to constrain the extension paths of the first and second optical fibers.

[0019] In conjunction with the first aspect, in some feasible embodiments, the optical transmission component further includes a sheath in which both the second optical fiber and the first optical fiber are enclosed.

[0020] In this way, the sheath can protect the first and second optical fibers and reduce the impact of dust or moisture on the first and second optical fibers.

[0021] In conjunction with the first aspect, in some feasible embodiments, the first connector includes a first housing and a first insert, the first housing being fitted over the first insert; the second connector includes a second housing and a second insert, the second housing being fitted over the second insert; the first housing is snapped or bonded to the second housing.

[0022] Thus, during the assembly of the housing structure, the independent first and second housings can be snapped or glued together to connect the first and second joints.

[0023] In conjunction with the first aspect, in some feasible embodiments, the insertion direction of the second connector forms an angle with the insertion direction of the first connector. If the first or second connector is a female connector, the insertion direction of the first or second connector can be the direction in which the female connector is inserted.

[0024] Thus, the extension direction of the device that plugs into the second connector has an angle with the length direction of the first ferrule. When the length of the device that plugs into the second connector is the same, the length of the structural assembly after the device that plugs into the second connector and the second optical connector are connected can be reduced.

[0025] In conjunction with the first aspect, in some feasible ways, the end faces of the first ferrule and the end faces of the second ferrule are arranged opposite to each other.

[0026] Thus, the device that abuts against the end face of the first ferrule and the device that abuts against the end face of the second ferrule are positioned opposite each other. This is suitable for scenarios where the devices that abut against the end face of the first ferrule and the end face of the second ferrule are large in size.

[0027] In conjunction with the first aspect, in some feasible embodiments, the first connector further includes a guide portion disposed outside the first housing, the guide portion extending in the same direction as the insertion direction of the first connector.

[0028] Thus, during the insertion of the first connector, it is inserted along the extension direction of the guide portion. The guiding function of the guide portion makes the insertion process of the first connector smoother.

[0029] In conjunction with the first aspect, in some feasible embodiments, the second housing is provided with a guide opening that is oriented in the same direction as the insertion direction of the second connector.

[0030] Thus, during the insertion of the second connector, it is inserted along the extension direction of the guide opening. The guiding function of the guide opening makes the insertion process of the second connector smoother.

[0031] In conjunction with the first aspect, in some feasible embodiments, the first connector further includes a frame sleeve fitted over the first insert, and the first housing fitted over the frame sleeve. Thus, the frame sleeve serves to secure the first insert, and the first housing is connected to the first insert via the frame sleeve.

[0032] In conjunction with the first aspect, in some feasible embodiments, the second connector further includes a sleeve fitted over the second ferrule, and the second housing fitted over the sleeve. Thus, the sleeve serves to protect the second ferrule, and also connects the second housing and the sleeve.

[0033] In conjunction with the first aspect, in some feasible embodiments, the second connector further includes a pull rod, one end of which is connected to the second housing and the other end is a free end, the pull rod being disposed opposite to the first connector.

[0034] During the insertion and removal of the second optical connector, the lever can provide a point of leverage, making the insertion and removal smoother. For example, the lever can provide a point of leverage during the insertion and removal of the first connector or the second connector, allowing the first and second connectors to be inserted and removed independently.

[0035] In conjunction with the first aspect, in some feasible ways, the shape of the first housing matches the shape of the second housing.

[0036] Thus, the internal shape of the device connected to the first housing is the same as or close to the internal shape of the second housing. Similarly, the external shape of the device connected to the second housing is the same as or close to the external shape of the first housing.

[0037] In conjunction with the first aspect, in some feasible ways, there is an angle between the insertion direction of the first connector and the insertion direction of the second connector.

[0038] Thus, the insertion directions of the first connector and the second connector are staggered. The extension directions of the device used to connect with the first connector and the extension directions of the device used with the second connector may not be parallel, and the second optical connector requires less space during assembly.

[0039] In conjunction with the first aspect, in some feasible ways, the free ends of the first connector and the free ends of the second connector are located at opposite ends of the second optical connector.

[0040] Thus, the device for connecting to the first connector and the device for connecting to the second connector are located at opposite ends of the second optical connector. Even if the device for connecting to the first connector or the device for connecting to the second connector is larger, both the first and second connectors can be well connected to other devices, simplifying wiring.

[0041] In conjunction with the first aspect, in some possible implementations, the first connector is a male SC connector and the second connector is a female SC connector. Alternatively, the first connector is a male FC connector and the second connector is a female FC connector. Alternatively, the first connector is a male ST connector and the second connector is a female ST connector. Alternatively, the first connector is a male LC connector and the second connector is a female LC connector.

[0042] When the first connector is a male SC connector and the second connector is a female SC connector, the first connector can be connected to the female SC connector, and the second connector can be connected to the male SC connector. By connecting the first connector to the female SC connector and the second connector to the male SC connector, the optical transmission component can be applied to links with SC connectors.

[0043] In the case where the first connector is a male ST connector and the second connector is a female ST connector, the optical transmission component can be applied to links with ST connectors.

[0044] In the case where the first connector is a male LC connector and the second connector is a female LC connector, the optical transmission component can be applied to links with LC connectors.

[0045] In conjunction with the first aspect, in some feasible ways, the first optical connector is an FC connector, an SC connector, an ST connector, or an LC connector.

[0046] In this way, the first optical connector can be configured according to the type of device connected to it, making the optical transmission component adaptable to various application scenarios.

[0047] Secondly, this application provides an optical transmission component. The optical transmission component includes a first optical connector, a second optical connector, a first optical fiber, a multiplexer, a second optical fiber, and a third optical fiber. The second optical connector includes a first connector and a second connector connected to each other. One end of the first optical fiber is connected to the first connector. One end of the second optical fiber is connected to the second connector. One end of the third optical fiber is connected to the first optical connector. The ends of the third optical fiber away from the first optical connector, the ends of the second optical fiber away from the second connector, and the ends of the first optical fiber away from the first connector are all connected to the multiplexer. The multiplexer is used to combine a first beam from the third optical fiber and a second beam from the second optical fiber, and output a third beam through the first optical fiber.

[0048] Thus, the second and first optical fibers share the space between the second optical connector and the multiplexer. The extension paths of the second and first optical fibers can be the same or very close. Compared to having different extension paths for the second and first optical fibers, the wiring of the optical transmission components is simpler, and the wiring space required for the optical transmission components is smaller. This is beneficial for making network equipment that includes optical transmission components more compact and reducing the space occupied by network equipment.

[0049] Thirdly, this application provides an optical communication device. The optical communication device includes: a single board and any one of the optical transmission components provided in the first and second aspects above, wherein the first connector is connected to the single board.

[0050] Because the wiring of optical transmission components is simpler, more space can be provided for other components within optical communication equipment.

[0051] Fourthly, this application provides an optical fiber connector. The optical fiber connector includes a first connector, a second connector, a first optical fiber, and a second optical fiber. One end of the first optical fiber is connected to the first connector. One end of the second optical fiber is connected to the second connector. The first connector is a male connector, and the second connector is a female connector; or, the first connector is a female connector, and the second connector is a male connector.

[0052] In conjunction with the fourth aspect, in some feasible embodiments, the first connector includes a first housing and a first insert, the first housing being fitted over the first insert; the second connector includes a second housing and a second insert, the second housing being fitted over the second insert; the first housing is snapped or bonded to the second housing.

[0053] In conjunction with the fourth aspect, in some feasible ways, the insertion direction of the second connector has an angle with the length direction of the first ferrule.

[0054] In conjunction with the fourth aspect, in some feasible ways, the end faces of the first ferrule and the end faces of the second ferrule are arranged opposite to each other.

[0055] In conjunction with the fourth aspect, in some feasible embodiments, the second connector further includes a pull rod, one end of which is connected to the second housing and the other end is a free end, the pull rod being disposed opposite to the first connector.

[0056] In conjunction with the fourth aspect, in some feasible ways, the shape of the first housing matches the shape of the second housing.

[0057] In conjunction with the fourth aspect, in some feasible ways, there is an angle between the insertion direction of the first connector and the insertion direction of the second connector.

[0058] In conjunction with the fourth aspect, in some feasible ways, the free ends of the first connector and the free ends of the second connector are located at opposite ends of the second optical connector.

[0059] In conjunction with the fourth aspect, in some possible implementations, the first connector is a male SC connector and the second connector is a female SC connector. Alternatively, the first connector is a male FC connector and the second connector is a female FC connector. Alternatively, the first connector is a male ST connector and the second connector is a female ST connector. Alternatively, the first connector is a male LC connector and the second connector is a female LC connector.

[0060] In conjunction with the fourth aspect, in some feasible embodiments, the first connector further includes a guide portion disposed outside the first housing, the guide portion extending in the same direction as the insertion direction of the first connector.

[0061] In conjunction with the fourth aspect, in some feasible embodiments, the second housing is provided with a guide opening, the direction of which is the same as the insertion direction of the second connector.

[0062] In conjunction with the fourth aspect, in some feasible embodiments, the first connector further includes a frame sleeve fitted over the first insert, and the first housing fitted over the frame sleeve.

[0063] In conjunction with the fourth aspect, in some feasible embodiments, the second connector further includes a sleeve fitted over the second insert, and the second housing fitted over the sleeve.

[0064] In conjunction with the fourth aspect, in some feasible embodiments, the second connector further includes a pull rod, one end of which is connected to the second housing and the other end is a free end, the pull rod being disposed opposite to the first connector.

[0065] Regarding the beneficial effects of the second, third, and fourth aspects, please refer to the description of any optional implementation method in the first aspect, which will not be repeated here. Based on the implementation methods provided in the above aspects, this application can also be further combined to provide more implementation methods. Attached Figure Description

Detailed Implementation

[0078] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0079] In the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more. "At least one" or similar expressions refer to any combination of these items, including any combination of a single item or a plurality of items. For example, at least one of a, b, and c can represent: a, b, c, ab, ac, bc, or abc, where a, b, and c can be a single item or multiple items.

[0080] Furthermore, to facilitate a clear description of the technical solutions in the embodiments of this application, the terms "first" and "second" are used in the embodiments of this application to distinguish identical or similar items with substantially the same function and effect. Those skilled in the art will understand that the terms "first" and "second" do not limit the quantity or execution order, and that "first" and "second" are not necessarily different. Meanwhile, in the embodiments of this application, words such as "exemplarily" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design scheme described as "exemplarily" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design schemes. Specifically, the use of words such as "exemplarily" or "for example" is intended to present related concepts in a concrete manner for ease of understanding.

[0081] In describing some embodiments, the term "connection" and its derivative expressions are used. The term "connection" should be interpreted broadly; for example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, the use of "based on" implies openness and inclusivity, because processes, steps, calculations, or other actions "based on" one or more of the stated conditions or values ​​may in practice be based on additional conditions or values ​​beyond those stated.

[0082] In the accompanying drawings, the thickness of some layers or regions has been selectively exaggerated for clarity, and the dimensional proportions between the portions shown do not reflect actual dimensional proportions. Therefore, variations in shape relative to the drawings are conceivable due to factors such as manufacturing techniques and / or tolerances. Consequently, exemplary embodiments should not be construed as being limited to the shapes of the regions shown in this application, but rather include shape deviations caused, for example, by manufacturing processes. For instance, etched areas shown as rectangular would typically have curved features. Therefore, the regions shown in the drawings are schematic in nature, and their shapes are not intended to show the actual shapes of areas of the device, nor are they intended to limit the scope of the exemplary embodiments.

[0083] Figure 1This is a schematic diagram of an optical network structure. Please refer to [link / reference]. Figure 1 An optical network includes optical network terminals, optical distribution frames (ODFs), and optical network units (ONUs). In some embodiments, an optical network unit may also be an optical network terminal (ONT).

[0084] The Optical Network Terminal (OLT) transmits network signals to the Optical Network Unit (ONU) or Optical Network Terminal (ONT) via multiple optical fibers through the Optical Distribution Frame (ODF). During this process, if any optical fiber fails, it is necessary to identify and repair that fiber.

[0085] Figure 1 In this context, the optical network terminal (OLT) includes a digital optical artificial intelligence (OAI) board and a passive optical network (PON) board.

[0086] The test light output from the digital optical path board (OAI) is sent to the multiplexer via the optical switch (OSW). The service light output from the optical module of the passive optical network board is sent to the multiplexer. The multiplexer combines the test light from the optical switch and the service light from the optical module and then sends them to the optical fiber distribution frame (ODF), so that the optical signals including the test light and the service light can be transmitted in the optical line distribution network.

[0087] The location of a fault in an optical network terminal can be identified by recognizing the signal of the test light.

[0088] An optical transmission module, or simply an optical module, consists of two main parts: a Bi-directional Optical Sub-assembly (BOSA) and an Electrical Sub-assembly (ESA). The BOSA is electrically connected to the ESA, and then the components are housed within the optical module housing to form the optical transmission module. It primarily comprises a Transmitting Optical Sub-assembly (TOSA) and a Receiving Optical Sub-assembly (ROSA). The TOSA converts electrical signals into optical signals and transmits them through the optical fiber. The ROSA receives the optical signals transmitted through the fiber and converts them back into electrical signals.

[0089] This application does not limit the transmission rate in the optical network; the transmission rate in the optical network can be 10Gbps (Gigabits per second), 50Gbps, or higher. The optical network provided in this application can be used in Optical Distribution Network (ODN) scenarios.

[0090] The optical network terminal provided in this application embodiment can improve its integration and reduce its size.

[0091] This application provides an optical communication device, which can be the aforementioned optical network terminal. This optical communication device has the advantages of high integration and compact structure.

[0092] This communication equipment includes multiple service boards and an optical transmission component. The optical transmission component connects the multiple service boards for optical transmission. In some scenarios, a service board can also be called a single board or a motherboard.

[0093] Figure 2 This is a schematic diagram of the structure of an optical transmission component 100 provided in an embodiment of this application. Please refer to... Figure 2 The optical transmission component 100 includes a first optical connector 110, a second optical connector 120, and a multiplexer 130. The second optical connector 120 includes two connectors, namely a first connector 121 and a second connector 122, which are interconnected.

[0094] The first optical connector 110, the second optical connector 120, and the multiplexer 130 are connected by optical fiber. The multiplexer 130 is used to combine the first beam from the first optical connector 110 and the second beam from the first connector 121 of the second optical connector 120, and output the third beam through the second connector 122 of the second optical connector 120.

[0095] Thus, the transmission paths of both the second and third beams include the location of the second optical connector 120 to the location of the multiplexer 130. The transmission paths of the second and third beams are very close. The wiring of the optical transmission component 100 is simpler, and the optical transmission component 100 requires less wiring space, which is beneficial for making network equipment including the optical transmission component 100 more compact and reducing the space occupied by the network equipment.

[0096] In addition, the second optical connector 120 includes two interconnected joints that are relatively compact. Compared to the first joint 121 and the second joint 122 being located in separate fiber optic connectors, the space required to install the first joint 121 and the second joint 122 is smaller, which helps to reduce the space occupied by the optical transmission assembly 100.

[0097] For example, the first optical connector 110 can be regarded as an optical fiber connector. One end of the optical fiber extends into the optical fiber connector and connects with it.

[0098] In some embodiments of this application, the first connector 121 is a male connector and the second connector 122 is a female connector; or, the first connector 121 is a female connector and the second connector 122 is a male connector. A male connector is a connector that inserts into a device and has protrusions or bumps to facilitate insertion. A female connector is a connector that receives a male connector and has a slot or hole corresponding to the male connector. Thus, one connector of the second optical connector 120 can be inserted into a device, and the other connector can be plugged into other devices.

[0099] It is understandable that the shape of the second connector 122 can be adapted to the shape of the first connector 121, so that the second connector 122 and the first connector 121 can be used as male and female connectors respectively. Alternatively, the shape of the second connector 122 can be unsuitable for the first connector 121, and the second connector 122 can be used as male and female connectors with other connectors, and the first connector 121 can be used as male and female connectors with other connectors.

[0100] In the embodiments of this application, the optical transmission component 100 may no longer be provided with devices for supporting the multiplexer 130. For example, the frame for supporting the multiplexer 130 may no longer be provided, which saves space for the network device and avoids the problem of introducing a fault point due to the provision of devices for supporting the multiplexer 130.

[0101] In some embodiments of this application, the optical transmission assembly 100 further includes a second optical fiber 202, a first optical fiber 201, and a third optical fiber 203. One end of the third optical fiber 203 is connected to the first optical connector 110, and the other end of the third optical fiber 203 is connected to the multiplexer 130. The third optical fiber 203 transmits the light beam from the first optical connector 110 to the multiplexer 130. The third optical fiber 203 is used to transmit the first light beam output from the first optical connector 110 to the multiplexer 130.

[0102] One end of the second optical fiber 202 is connected to the second connector 122, and the other end of the second optical fiber 202 is connected to the multiplexer 130. The second optical fiber 202 transmits the beam from the second connector 122 to the multiplexer 130. The second optical fiber 202 is also used to transmit the third beam output from the multiplexer 130 to the second connector 122.

[0103] One end of the first optical fiber 201 is connected to the first connector 121, and the other end of the first optical fiber 201 is connected to the multiplexer 130. The first optical fiber 201 transmits the light beam from the first connector 121 to the multiplexer 130. The first optical fiber 201 is also used to transmit a second light beam from the first connector 121 to the multiplexer 130.

[0104] The beam combiner 130 is used to combine the beam from the third fiber 203 and the beam from the second fiber 202 and output them through the first fiber 201.

[0105] Thus, the second optical fiber 202 and the first optical fiber 201 share the space between the second optical connector 120 and the multiplexer 130. The extension paths of the second optical fiber 202 and the first optical fiber 201 can be the same or very close. Compared with different extension paths of the second optical fiber 202 and the first optical fiber 201, the wiring of the optical transmission component 100 is simpler, and the optical transmission component 100 requires less wiring space. This is beneficial for making the network equipment including the optical transmission component 100 more compact and reducing the space occupied by the network equipment.

[0106] For example, the multiplexer 130 can be a wavelength division multiplexing (WDM) device. The WDM device can be implemented in a tubular structure or a planar lightwave circuit (PLC) structure, and the shape of the WDM device can be cylindrical or square.

[0107] Wavelength division multiplexing (WDM) is a technique that combines two or more optical carrier signals of different wavelengths (carrying various information) at the transmitting end using a multiplexer (also called a multiplexer) and couples them into the same optical fiber for transmission. At the receiving end, a demultiplexer (also called a demultiplexer) separates the optical carriers of different wavelengths, and then the optical receiver performs further processing to recover the original signal. This technique of simultaneously transmitting two or more different wavelength optical signals in the same optical fiber is called wavelength division multiplexing.

[0108] In the embodiments of this application, the multiplexer 130 can be located in the optical path between the first optical connector 110 and the second optical connector 120. The multiplexer 130 is not directly connected to the first optical connector 110, nor is it directly connected to the second optical connector 120. Thus, based on the connection of the multiplexer 130 to the third optical fiber 203, the second optical fiber 202, and the first optical fiber 201, the multiplexer 130 can be located at any position between the first optical connector 110 and the second optical connector 120. Furthermore, because the third optical fiber 203, the second optical fiber 202, and the first optical fiber 201 are flexible structures, the position of the multiplexer 130 can be adjusted by bending them. During the assembly of the optical transmission assembly 100, the multiplexer 130 can be adjusted according to the space available for installing the optical transmission assembly 100, making the wiring more flexible.

[0109] In some embodiments of this application, to constrain the first optical fiber 201 and the second optical fiber 202, the second optical connector 120 further includes wire teeth 123. The wire teeth 123 are connected to the second connector 122, forming a channel through which the first optical fiber 201 and the second optical fiber 202 pass. Thus, the wire teeth 123 can constrain the relative positions of the first optical fiber 201, the second optical fiber 202, and the second optical connector 120, preventing the first optical fiber 201 and the second optical fiber 202 from deviating too far from the second optical connector 120. This contributes to cleaner wiring.

[0110] The embodiments of this application do not limit the number of wire teeth 123. The number of wire teeth 123 can be one, two, three or more.

[0111] For example, the wire tooth 123 can be an L-shaped structure, which facilitates the insertion of the first optical fiber 201 and the second optical fiber 202 into the channel from one end of the wire tooth 123 during assembly. In other embodiments of this application, the wire tooth 123 can be an irregular shape. For example, the wire tooth 123 can be an S-shaped structure, etc.

[0112] In some embodiments of this application, the wire tooth 123 can be connected to the first connector 121. For the connection method between the wire tooth 123 and the first connector 121, please refer to the aforementioned description of the connection method between the wire tooth 123 and the second connector 122, which will not be repeated here.

[0113] In some embodiments of this application, the outer surface of the second connector 122 includes an arc-shaped surface A, to which both the first optical fiber 201 and the second optical fiber 202 are attached. Thus, the arc-shaped surface A constrains the paths of the first optical fiber 201 and the second optical fiber 202 extending on the outer surface of the second connector 122 to be arc-shaped. This makes the bending radii of the first optical fiber 201 and the second optical fiber 202 close to the radius of the arc-shaped surface A. The arc-shaped surface A constrains the minimum bending radius of the first optical fiber 201 and the second optical fiber 202, preventing the first optical fiber 201 and the second optical fiber 202 from being too small during assembly, which could lead to signal loss within the optical fibers.

[0114] The radius of the arc-shaped surface A can be set according to the minimum bending radius acceptable to the first optical fiber 201 and the second optical fiber 202.

[0115] In some embodiments of this application, the first optical fiber 201 and the second optical fiber 202 are bonded to the curved surface A. This prevents the first optical fiber 201 and the second optical fiber 202 from sliding on the curved surface A. It also helps to constrain the extension paths of the first optical fiber 201 and the second optical fiber 202.

[0116] In some embodiments of this application, the first optical fiber 201 and the second optical fiber 202 may not be connected to the arc-shaped surface A. The wire teeth 123 may restrict the movement space of the first optical fiber 201 and the second optical fiber 202.

[0117] exist Figure 2 In this example, the optical transmission assembly 100 also includes a sheath 204. Both the first optical fiber 201 and the second optical fiber 202 are enclosed within the sheath 204. Thus, the sheath 204 protects the first optical fiber 201 and the second optical fiber 202, reducing the impact of dust or moisture on them.

[0118] In some embodiments, there are two sheaths 204: one sheath 204 encloses the first optical fiber 201 and the second optical fiber 202, and the other sheath 204 encloses the third optical fiber 203.

[0119] Figure 3 This is a schematic diagram of another optical transmission component 100 provided in an embodiment of this application. Figure 3 and Figure 2 The differences include the different positions of the combiner 130.

[0120] Figure 3 In this example, the multiplexer 130 is fixedly connected to the first optical connector 110. This makes the connection between the multiplexer 130 and the first optical connector 110 more compact.

[0121] For example, the multiplexer 130 can be integrated into the first optical connector 110. For instance, the multiplexer 130 can be integrated into the tail sleeve of the first optical connector 110.

[0122] In addition, the multiplexer 130 is fixedly connected to the first optical connector 110, and the first optical connector 110 can provide support for the multiplexer 130.

[0123] Figure 3 For the remaining structures, please refer to Figure 2 The description of the example shown will not be repeated here.

[0124] Figure 4 This is a schematic diagram of the structure of another optical transmission component 100 provided in an embodiment of this application. Figure 4 and Figure 2 The differences include the different positions of the combiner 130.

[0125] Figure 4 In this example, the multiplexer 130 is fixed to the first connector 121, or the multiplexer 130 is fixed to the second connector 122. Thus, the multiplexer 130 is connected to the second optical connector 120. The multiplexer 130 and the second optical connector 120 are more compact.

[0126] Figure 4 For the remaining structures, please refer to Figure 2 The description of the example shown will not be repeated here.

[0127] The embodiments of this application do not limit the type of the first optical connector 110. Exemplarily, the first optical connector 110 is an FC (ferrule connector), an SC (subscriber connector / square connector), an ST (straight tip) connector, or an LC (Lucent connector).

[0128] In this way, the first optical connector 110 can be configured according to the type of device connected to it, so that the optical transmission component 100 can be adapted to various application scenarios.

[0129] In some embodiments of this application, there is an angle between the insertion direction of the first connector 121 and the insertion direction of the second connector 122. Exemplarily, the insertion directions of the first connector 121 and the second connector 122 are opposite and not parallel.

[0130] Thus, the insertion direction of the first connector 121 and the insertion direction of the second connector 122 are offset. The extension directions of the device used to connect with the first connector 121 and the extension directions of the device used with the second connector 122 may not be parallel, so that the second optical connector 120 requires less space during assembly.

[0131] The insertion direction of the first connector 121 is the direction of the force exerted by the first connector 121 on other devices during the connection process between the first connector 121 and other devices, for example... Figure 2 The first insertion direction is specified in the diagram. The insertion direction of the second connector 122 is the direction of the force exerted by the second connector 122 on other devices during the connection process, for example... Figure 2 The second insertion direction. The first insertion direction and the second insertion direction are not parallel; the first insertion direction and the second insertion direction are opposite.

[0132] For example, the angle between the first insertion direction and the second insertion direction is in the range of 140°-220°, and the angle between the first insertion direction and the second insertion direction is not 180°. For example, the angle between the first insertion direction and the second insertion direction can be 140°, 145°, 150°, 155°, 158°, 160°, 165°, 170°, 175°, 177°, 179°, 185°, 188°, 190°, 195°, 200°, 205°, 210°, 215°, or 220°, etc.

[0133] The embodiments of this application do not limit the types of the first connector 121 and the second connector 122.

[0134] In some embodiments of this application, the first connector 121 is a male SC connector, and the second connector 122 is a female SC connector. Thus, the first connector 121 can be connected to the female SC connector, and the second connector 122 can be connected to the male SC connector. The second optical connector 120 can be embedded between the SC connectors. For example, by unplugging the female and male SC connectors, connecting the first connector 121 to the female SC connector, and the second connector 122 to the male SC connector, the optical transmission component 100 can be applied to a link with SC connectors.

[0135] In some embodiments of this application, the first connector 121 is a male FC connector and the second connector 122 is a female FC connector. Similarly, the optical transmission component 100 can be applied to links with FC connectors.

[0136] In some embodiments of this application, the first connector 121 is a male ST connector and the second connector 122 is a female ST connector. Similarly, the optical transmission component 100 can be applied to links with ST connectors.

[0137] In some embodiments of this application, the first connector 121 is a male LC connector and the second connector 122 is a female LC connector. Similarly, the optical transmission component 100 can be applied to links with LC connectors.

[0138] In some embodiments of this application, the first connector 121 is a male SC connector, and the second connector 122 can be a female FC connector, a female ST connector, or a female LC connector. The configuration can be tailored to the specific application scenario of the second optical connector 120. Figure 2 In the example, the first connector 121 is a male SC connector, and the second connector 122 is a female SC connector.

[0139] Figure 5 This is a schematic diagram of the internal structure of a second optical connector 120 provided in an embodiment of this application. Please refer to... Figure 5 The first connector 121 includes a first housing 211 and a first insert 212, with the first housing 211 sleeved over the first insert 212. The second connector 122 includes a second housing 221 and a second insert 222, with the second housing 221 sleeved over the second insert 222. The first housing 211 and the second housing 221 are snap-fitted or glued together. Thus, during the assembly of the second optical connector 120, the independent first housing 211 and second housing 221 can be snap-fitted or glued together to connect the first connector 121 and the second connector 122.

[0140] The first ferrule 212 is fitted onto the first optical fiber 201 (e.g., ...). Figure 2 The first ferrule 212 is flush with the end face of the first optical fiber 201. The second ferrule 222 is fitted onto one end of the second optical fiber 202 (as shown in the image), and the end face of the first ferrule 212 is flush with the end face of the first optical fiber 201. Figure 2 (as shown) one end, and the end face of the second ferrule 222 is flush with the end face of the second optical fiber 202.

[0141] In some embodiments of this application, the free ends of the first connector 121 and the second connector 122 are located at opposite ends of the second optical connector 120. Thus, the device for connecting to the first connector 121 and the device for connecting to the second connector 122 are located at opposite ends of the second optical connector 120. Even if the device for connecting to the first connector 121 or the device for connecting to the second connector 122 is larger, both the first connector 121 and the second connector 122 can be better connected to other devices, simplifying wiring.

[0142] In some embodiments, the first connector 121 is connected to the first optical fiber 201, with the first optical fiber 201 extending from one end of the first connector 121. The free end of the first connector 121 refers to the end of the first connector 121 that does not extend from the first optical fiber 201, or the end opposite to the end that extends from the first optical fiber 201. The same applies to the free end of the second connector 122.

[0143] The free ends of the first connector 121 and the second connector 122 face opposite directions. Figure 3 For example, the free end of the first connector 121 faces to the left, and the free end of the second connector 122 faces to the right.

[0144] In this way, the device for connecting to the first connector 121 and the device for connecting to the second connector 122 are respectively connected from opposite sides of the second optical connector 120. This avoids the problem of wiring congestion caused by the devices for connecting to the first connector 121 and the devices for connecting to the second connector 122 being located on the same side.

[0145] In some embodiments of this application, the end face of the first ferrule 212 and the end face of the second ferrule 222 are arranged opposite to each other. Thus, the device that abuts against the end face of the first ferrule 212 and the device that abuts against the end face of the second ferrule 222 are arranged opposite to each other. This is suitable for scenarios where the devices abutting against the end face of the first ferrule 212 and the end face of the second ferrule 222 are large.

[0146] For example, the insertion direction of the second connector 122 forms an angle with the length direction of the first ferrule 212. In this way, with the same length of the device inserted with the second connector 122, the length of the structural assembly after connecting the device inserted with the second connector 122 and the second optical connector can be reduced.

[0147] Figure 6a A schematic diagram of the internal structure of the first connector 121 provided in an embodiment of this application. Please refer to... Figure 6a In some embodiments, the first connector 121 further includes a frame sleeve 213, which is sleeved over the first insert 212, and the first housing 211 is sleeved over the frame sleeve 213. The frame sleeve 213 serves to fix the first insert 212, and the first housing 211 is connected to the first insert 212 through the frame sleeve 213.

[0148] The shape of the frame 213 is not limited in this embodiment. For example, the frame 213 is a cylindrical structure and is arranged around the first insert 212.

[0149] In some embodiments, the first connector 121 further includes an elastic element 214 and a base 215, the base 215 being elastically connected to the first insert 212 via the elastic element 214. Both the elastic element 214 and the base 215 are located within the frame 213.

[0150] The elastic element 214 is in a compressed state. The elastic force of the elastic element 214 keeps the base 215 and the frame sleeve 213 in a resisting state, making the connection between the base 215 and the frame sleeve 213 tighter.

[0151] For example, the elastic element 214 can be a spring.

[0152] Figure 6a In the example, an elastic arm 219 is also provided at the end of the first housing 211. The elastic arm 219 is located on the first housing 211 near the second connector 122 (e.g., Figure 5 (as shown). For example, the elastic arm 219 is integrally formed with the first housing 211.

[0153] For example, the number of flexible arms 219 can be one, two or more.

[0154] Figure 6b This is an exploded structural diagram of the first connector 121 provided in an embodiment of this application. Please refer to... Figure 6b In some embodiments, a protrusion 216 is provided on the base 215, and a through hole 217 is provided on the first housing 211. The through hole 217 and the protrusion 216 are engaged, thereby connecting the base 215 and the first housing 211.

[0155] In some embodiments of this application, the first connector 121 further includes a guide portion 218, which is disposed outside the first housing 211, and the extending direction of the guide portion 218 is the same as the insertion direction of the first connector 121.

[0156] Thus, during the insertion of the first connector 121, it is inserted along the extending direction of the guide portion 218. The guiding function of the guide portion 218 makes the insertion process of the first connector 121 smoother.

[0157] Figure 6b In the middle, the guide part 218 protrudes from the outer surface of the first housing 211.

[0158] Figure 7 This is a schematic diagram of the internal structure of the second connector 122 provided in an embodiment of this application. Please refer to... Figure 7In some embodiments of this application, the second connector 122 may further include a sleeve 223, which is sleeved over the second ferrule 222, and the second housing 221 is sleeved over the sleeve 223. Thus, the sleeve 223 serves to protect the second ferrule 222, and the sleeve 223 can also connect the second housing 221 and the sleeve 223.

[0159] For example, the sleeve 223 can be made of ceramic material.

[0160] The length of the sleeve 223 is greater than the length of the second ferrule 222. When the second connector 122 is connected to other devices such as fiber optic connectors, parts of the other devices extend into the sleeve 223 and abut against the second ferrule 222.

[0161] Figure 7 In the example, the second housing 221 is provided with a plurality of grippers 224 extending toward the insertion direction of the second connector 122. When the second connector 122 is connected to other devices, such as fiber optic connectors, portions of the other devices extend into the second housing 221 and are held by the plurality of grippers 224.

[0162] Figure 7 In the example, the second housing 221 is provided with a guide opening 225, the direction of which is the same as the insertion direction of the second connector 122.

[0163] Thus, during the insertion of the second connector 122, it is inserted along the extending direction of the guide opening 225. The guiding function of the guide opening 225 makes the insertion process of the second connector 122 smoother.

[0164] Figure 8 This is an exploded structural diagram of the second connector 122 provided in an embodiment of this application. Please refer to... Figure 8 The second connector 122 also includes a pull rod 226, one end of which is connected to the second housing 221, and the other end of which is a free end. The pull rod 226 and the first connector 121 (as shown in the image) Figure 5 (As shown) opposite settings.

[0165] Second optical connector 120 (e.g.) Figure 5 During the insertion and removal process (as shown), the lever 226 can provide a point of force to make the insertion and removal smoother. For example, during the insertion and removal of the first connector 121 or the second connector 122, the lever 226 can provide a point of force, and the first connector 121 and the second connector 122 can be inserted and removed independently.

[0166] This application does not limit the connection method of the pull rod 226 and the second housing 221. In some embodiments, the pull rod 226 and the second housing 221 are connected as a single molded part. In some embodiments, the pull rod 226 and the second housing 221 are bonded together. In some embodiments, the pull rod 226 and the second housing 221 are detachably connected by snap-fit ​​or screw-fit.

[0167] Furthermore, without affecting the insertion and removal of the second connector 122, the pull rod 226 can be connected to any position of the second housing 221, and this application embodiment does not impose any restrictions on this.

[0168] The shape of the pull rod 226 is not limited in this application embodiment. For example, the pull rod 226 is a long strip-shaped structure. In some embodiments, the surface of the pull rod 226 is provided with anti-slip texture, which facilitates gripping the pull rod 226.

[0169] Figure 8 In the example, the end of the second housing 221 is also provided with a slot 227. The slot 227 is located on the second housing 221 near the first connector 121 (e.g., Figure 5 (as shown in the figure) at one end.

[0170] First shell 211 (as shown) Figure 6b The elastic arm 219 on the (as shown) Figure 6b (As shown) It extends into the slot 227 and engages with the slot 227, so that the first housing 211 and the second housing 221 are engaged.

[0171] In other embodiments of this application, the elastic arm 219 on the first housing 211 is not necessary, the slot 227 on the second housing 221 is not necessary, and the first housing 211 and the second housing 221 can be connected in other ways. For example, the first housing 211 and the second housing 221 can be bonded together by dispensing adhesive.

[0172] In embodiments of this application, the shapes of the first housing 211 and the second housing 221 are matched. The external shape of the first housing 211 matches the internal shape of the second housing 221. Thus, the internal cavity shape of the device connected to the first housing 211 is the same as or close to the internal shape of the second housing 221. Similarly, the external shape of the device connected to the second housing 221 is the same as or close to the external shape of the first housing 211.

[0173] In this way, the first device and the second device can be removed, the first device can be connected to the first housing 211 of the first connector, and the second device can be connected to the second housing 221 of the second connector. The first device can be, for example, an adapter, and the second device can be, for example, an optical fiber connector. The optical transmission component 100 can be applied to the already assembled link.

[0174] In the embodiment where the first connector 121 is a male SC connector and the second connector 122 is a female SC connector, the outer shape of the first housing 211 is the outer shape of the housing of the male SC connector, and the inner shape of the second housing 221 is the inner shape of the housing of the female SC connector. The same applies to other embodiments.

[0175] Figure 2 , Figure 3 and Figure 4 In the example, the first connector 121 is a male SC connector, and the second connector 122 is a female SC connector. As mentioned above, the first connector 121 provided in the embodiments of this application may not be limited to a male SC connector, and the second connector 122 may not be limited to a female SC connector.

[0176] Figure 9 This is a schematic diagram of the structure of a second optical connector 120 provided in an embodiment of this application. Figure 9 and Figure 5 The differences include: the first connector 121 and the second connector 122 have different shapes.

[0177] Figure 9 In the example, the first connector 121 is a male SC connector, and the second connector 122 is a female LC connector. Similarly, the first housing 211 of the first connector 121 is the housing of the male SC connector, and the second housing 221 of the second connector 122 is the housing of the female LC connector.

[0178] exist Figure 9 In the example, the size and shape of the second ferrule of the second connector 122 can be set according to the requirements of the male LC connector for the size and shape of the first ferrule. For example, the outer diameter of the second ferrule is 1.25 mm. The outer diameter of the second ferrule of the second connector 122 is 1.25 mm.

[0179] The same applies to the other components in the first connector 121 and the second connector 122.

[0181] Figure 10 This is a schematic diagram of the structure of another second optical connector 120 provided in the embodiments of this application. Figure 10 and Figure 5 The differences include: the first connector 121 and the second connector 122 have different shapes.

[0182] Figure 10In the example, the first connector 121 is a male SC connector, and the second connector 122 is a female FC connector. Similarly, the first housing 211 of the first connector 121 is the housing of the male SC connector, and the second housing 221 of the second connector 122 is the housing of the female FC connector.

[0183] Figure 10 For other structures, please refer to the previous text. Figure 5 The description in the example shown.

[0184] In this embodiment, two optical beams, a second beam and a third beam, are transmitted between the second optical connector 120 and the multiplexer 130. Thus, the extension paths of the optical fiber used to transmit the second beam and the optical fiber used to transmit the third beam can be the same or close. This results in a simpler wiring configuration for the optical transmission assembly 100 and requires less cabling space.

[0185] The optical communication equipment provided in this application embodiment has simple wiring, which provides more space for other devices in the optical communication equipment and is conducive to the miniaturization of the optical communication equipment.
