Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to an optical fiber clamp, an optical fiber plug, an optical fiber adapter and a network device. Background Art

[0002] As the 5G, data center, and cloud computing markets continue to expand, high-complexity boards of network devices such as routers, switches, and servers are evolving toward high capacity and high bandwidth, and the density of single-board panels continues to increase. However, traditional pluggable optical modules are difficult to further improve due to standard size limitations, and high-complexity boards have gradually developed into on-board optical systems (On Board Optics, OBO) or co-packaged optics (Coup led Package Optics, CPO). In OBO or CPO technology, the optical signal is emitted from the OBO or chip and transmitted to the adapter on the panel side through the MT (Mechanical Transfer) core. The adapter is used to achieve the docking of the on-board fiber and the off-board optical fiber cable.

[0003] However, the fiber optic adapter can only achieve the docking of a single MT ferrule at a time, and the number of fiber optic channels is limited by the number of optical fibers in a single MT ferrule, making it difficult to further increase the number of fiber optic channels. Summary of the invention

[0004] In order to solve the above-mentioned problems, an optical fiber clamp, an optical fiber plug, an optical fiber adapter and a network device are provided in the embodiments of the present application, which further increase the number of optical fibers by increasing the number of MT ferrules in the optical fiber adapter interface.

[0005] To this end, the following technical solutions are adopted in the embodiments of the present application:

[0006] In a first aspect, an embodiment of the present application provides a fiber optic clamp, comprising a clamp seat and N fixing components, wherein the N fixing components are elastically connected to the clamp seat. After the fiber optic clamp fixes N MT optical fibers, it can be plugged into a fiber optic adapter, where N is an integer greater than or equal to 2. Each MT optical fiber includes an MT ferrule and a pigtail. N mounting portions are provided on two opposite walls of the clamp seat, and the N mounting portions are respectively used to install and fix the N pigtails. The N fixing components are respectively used to fix the N MT ferrules.

[0007] That is to say, the embodiment of the present application provides a fiber optic clamp that can fix N MT optical fibers. In the embodiment of the present application, after the fixing component and the clamp seat fix the MT ferrule and pigtail of the N MT optical fibers respectively, they can be plugged into the interface of the optical fiber adapter as a whole, and the integrated plugging and unplugging of the N MT optical fibers can be realized. Since each fixing component is elastically connected to the clamp seat, the MT ferrule can be adaptively docked with the docked MPO ferrule to realize the correct transmission of the optical signal. The clamp seat of the embodiment of the present application can be provided with N mounting parts to facilitate the disassembly and assembly of the MT optical fiber and the fiber optic clamp. The embodiment of the present application increases the number of optical fibers and improves the number of optical fibers by increasing the number of MT ferrules in the interface of the optical fiber adapter. In addition, after the optical fiber clamp that has been plugged and unplugged many times is deformed and damaged, the optical fiber clamp is simply replaced without scrapping the entire optical fiber plug including the MT optical fiber.

For example, when the grinding amount is large, the length of the MT ferrule or MPO ferrule will become shorter, and when the grinding amount is small, the length of the MT ferrule or MPO ferrule will become longer. The elastic element can change its own expansion and contraction amount according to the external force to achieve axial movement of the MT ferrule to match the docked MPO ferrule and adaptively align the length or end face inclination angle of the MPO ferrule. Therefore, each MT ferrule in the embodiment of the present application is provided with an independent elastic element to achieve independent floating of each MT ferrule, ensure that each pair of MT ferrules is adapted to the length, grinding angle, etc. of the docked MPO ferrule, ensure the close docking of each pair of MT ferrules and MPO ferrules, and ensure stable optical signal transmission.

DETAILED DESCRIPTION

[0076] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0077] The term "and / or" in this article is a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The symbol " / " in this article indicates that the associated objects are in an "or" relationship, for example, A / B means A or B.

[0078] The terms "first" and "second" in the specification and claims herein are used to distinguish different objects rather than to describe a specific order of the objects. For example, a first response message and a second response message are used to distinguish different response messages rather than to describe a specific order of the response messages.

[0079] In the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0080] In the description of the embodiments of the present application, unless otherwise specified, "multiple" means two or more than two. For example, multiple processing units refer to two or more processing units, etc.; multiple elements refer to two or more elements, etc.

[0081] As the 5G, data center, and cloud computing markets continue to expand, high-end routers / switches and other highly complex boards are evolving toward high capacity and high bandwidth, and the density of single-board panels will continue to increase. However, traditional pluggable optical modules are difficult to further improve due to standard size limitations, so highly complex boards have gradually developed into OBO (On Board Optics) or CPO (Coupled Package Optics) technology. In OBO or CPO technology, the optical signal is emitted from the OBO or chip and transmitted to the adapter on the panel side through the ribbon fiber. The adapter can achieve the docking of the MT (Mechanical Transfer) ribbon fiber inside the board and the MPO (Multiple-fiber push-on) optical fiber cable outside the board.

[0082] However, MT / MPO fiber adapters can only dock a single MT ferrule at a time, and the number of fiber channels is limited by the number of fibers in a single ferrule. In practical applications, increasing the number of fibers in a single ferrule to increase transmission capacity is difficult and costly to process, and will also introduce additional docking loss costs.

[0083] In order to solve the problem of low transmission capacity of optical fiber adapters, an embodiment of the present application proposes a fiber optic clamp. Multiple MT ferrules are placed inside the optical fiber clamp, which further increases the number of optical fiber channels. In the embodiment of the present application, the optical fiber clamp is provided with independent fixing components, each of which is equipped with an MT ferrule, so that each MT ferrule can float independently. The MT ferrule floats independently and can be matched with the MPO ferrule of the docking MPO plug to achieve accurate docking, thereby ensuring accurate transmission of optical signals.

[0084] In the embodiment of the present application, the fiber optic clamp can be used for any form of MT ferrule, such as standard MT ferrule, SFC (super fiber connector) ferrule, Mini MT ferrule, etc. Among them, the SFC ferrule is a thinned MT ferrule, the ferrule length and width of the SFC ferrule are consistent with the standard MT ferrule, and the thickness direction is thinned by half; the number of optical fibers arranged in the SFC ferrule is the same as that of the standard MT ferrule. Among them, the Mini MT ferrule is a MT ferrule designed for small spaces. The Mini MT ferrule can meet the connection situation in a small space because its volume is more than half that of the standard MT ferrule.

[0085] It should be further explained that due to the limitation of the grinding process in the MT ferrule processing, the ferrule lengths and grinding angles of the two pairs of ferrules used for mutual matching and alignment may be different, so it is difficult to dock the MT ferrule and the MPO ferrule. In the embodiment of the present application, each MT ferrule floats independently, which can ensure that the MT ferrule can adaptively adjust the axial position to adapt to the length and grinding angle of the MPO ferrule, so as to achieve reliable and stable docking between the MT ferrule and the MPO ferrule.

[0086] See also Figure 1a , Figure 1b , Figure 1a , Figure 1b FIG. 1 shows a schematic diagram of the structure of an optical fiber adapter. Figure 1a , Figure 1b As shown, an embodiment of the present application provides a fiber optic adapter. The fiber optic adapter includes: an adapter body 1, an MT fiber ribbon plug 6, and an MPO plug 5. In this application scenario, the adapter body 1 is fixedly mounted on the panel 4, and the MT fiber ribbon plug 6 and the MPO plug 5 are respectively plugged into the two sides of the adapter body 1. After plugging, the MT fiber ribbon plug 6 is connected to the MPO plug 5, and the optical signal data is transmitted from the MT fiber ribbon plug 6 to the MPO plug 5, realizing the conversion of different interfaces and the transmission of optical signals between different interfaces.

[0087] In order to facilitate description of the solution of the embodiment of the present application, the side where the MPO plug 5 is plugged in is called the outer side of the panel 4, and the side where the MT ribbon fiber plug 6 is plugged in is called the inner side of the panel 4.

[0088] like Figure 1b As shown, the MT fiber ribbon plug 6 includes a fiber ribbon card clip 2 and a fiber ribbon assembly 3. The fiber ribbon card clip 2 is used to fix and position the fiber ribbon assembly 3. When the MT fiber ribbon plug 6 is plugged into the adapter body 1, a high-performance connection between different interfaces at both ends of the adapter body 1 is achieved, thereby improving the stability of the transmission signal.

[0089] See also Figure 2 , Figure 2 A schematic diagram of the composition of a panel assembly including an optical fiber adapter is shown. Figure 2 As shown, in a panel 4, multiple fiber optic adapters as shown in FIG. 1 may be provided, or one fiber optic adapter may be provided with multiple interfaces to increase the number of fiber optic signal channels. Figure 2 As shown, in an application scenario, the panel 4 can be a panel. Exemplarily, based on the size requirements of the panel 4, four groups of optical fiber adapters are arranged on the panel 4, each group of optical fiber adapters includes an adapter body 1, each adapter body 1 is provided with eight grooves, each groove can be plugged with an MT fiber plug 6, an MPO plug 5.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of this application.

[0091] See also Figure 3 , Figure 3 FIG. 1 shows a schematic diagram of the structure of a panel. Figure 3 As shown, the panel 4 may be provided with a positioning structure, which plays a role in positioning and foolproofing when the adapter body 1 is installed on the panel 4. In addition, the panel 4 may also be provided with a structural member to strengthen the structure of the panel 4.

[0092] Exemplarily, a structural member is fixedly mounted on the panel 4, and the structural member is further provided with a mounting hole and a positioning hole. The mounting hole is used to mount the adapter body 1. The positioning hole is used to position the adapter body 1 when it is mounted.

[0093] Generally, the structural strength of the panel 4 is reduced due to the avoidance groove 406. In the embodiment of the present application, a structural member is fixedly mounted on the panel 4, which plays a role similar to a reinforcing rib, can strengthen the structural strength of the panel 4, and prevent deformation caused by the avoidance groove 406 of the panel 4 being too large.

[0094] For example, Figure 3 As shown, the panel 4 is riveted with a first structural member 401 and a second structural member 402 on both sides of the avoidance groove 406. The avoidance groove 406 is used to avoid the protruding structure of the adapter body 1. A first screw hole 403 with a thread is punched on the first structural member 401. A second screw hole 404 with a thread is left on the second structural member 402, and a positioning hole 405 is also provided. The first structural member 401 and the second structural member 402 are used to provide a fixed assembly of the optical fiber adapter, and are also used to strengthen the strength of the panel 4 to prevent deformation caused by the avoidance groove 406 of the panel 4 being too large. The riveting method of this example can also be connected by welding, bonding, and other connection methods, which are not limited in the embodiments of the present application.

[0095] See also Figure 4 , Figure 5 , Figure 6 , Figure 4-Figure 6 The schematic diagram of the structure of an adapter body is shown. The adapter body 1 is provided with a positioning structure corresponding to the panel 4, which plays a role in positioning and foolproofing when the adapter body 1 is installed on the panel 4.

[0096] For example, Figure 4As shown, the adapter body 1 is provided with a first mounting hole 101, a second mounting hole 102, and a positioning column 103. The first mounting hole 101 of the adapter body 1 cooperates with the first screw hole 403 of the first structural member 401 of the panel 4, and the second mounting hole 102 of the adapter body 1 cooperates with the second screw hole 404 of the second structural member 402 of the panel 4. Exemplarily, the adapter body 1 is fixedly mounted on the panel 4 using fasteners. The positioning column 103 of the adapter body 1 cooperates with the positioning hole 405 of the second structural member 402 of the panel 4 to achieve the positioning of the adapter body 1 equivalent to the panel 4.

[0097] For example, Figure 5 As shown, the adapter body 1 includes a first card slot 11. The first card slot 11 is used to plug the MPO plug 5.

[0098] For example, Figure 1a As shown, the external dimensions of the MPO plug 5 do not change, and only the space inside the interface needs to be adaptively modified to adapt and connect with the MT ribbon fiber plug 6, so the MPO plug 5 will not be further described in the embodiment of the present application to avoid the description of the embodiment of the present application being too lengthy. Similarly, the external dimensions of the MPO plug 5 do not change, so the first card slot 11 will not be further described in the embodiment of the present application.

[0099] For example, Figure 6 As shown, the adapter body 1 includes a second card slot 12. The second card slot 12 is used to plug the MT fiber ribbon plug 6. The second card slot 12 includes a fixed area 12-1 and a fiber ribbon connection area 12-2. The fixed area 12-1 is used to fix the fiber ribbon clamp 2 connected to the MT fiber ribbon plug 6. The fiber ribbon connection area 12-2 is used to connect the fiber ribbon assembly 3 of the MT fiber ribbon plug 6 to realize signal transmission from the fiber ribbon assembly 3 to the MPO plug 5 through the adapter body 1.

[0100] It can be further understood that, in the second card slot 12 of the adapter body 1, the structure of the fixing area 12-1 can be determined based on the shape of the connection part of the fiber ribbon card clip 2; the structure of the fiber ribbon connection area 12-2 can be determined based on the connection structure of the fiber ribbon assembly 3. In other words, the internal structure of the second card slot 12 can be determined based on the connection structure of the MT fiber ribbon plug 6. Therefore, the specific structure of the second card slot 12 will not be described here.

[0101] In a possible implementation, under the premise of an existing adapter body, by increasing the opening size inside the bare ferrule side in the second card slot 12, it is possible to provide assembly space for a double-piece MT ferrule. That is to say, in the embodiment of the present application, the outer dimensions of the adapter body 1 and the first card slot 11 on the side where the MPO plug 5 is plugged in are unchanged, supporting plug-back compatibility, low replacement cost, and strong adaptability. Therefore, the adapter body 1 of the embodiment of the present application achieves doubling of the number of optical fiber channels and doubling of the transmission capacity while maintaining the space occupied by the panel 4.

[0102] See also Figure 7a , Figure 7b , Figure 7c , Figures 7a to 7c The schematic diagram of the composition of a fiber-carrying card clamp is shown. The fiber-carrying card clamp is an example of an optical fiber clamp, and the structural dimensions of the fiber-carrying card clamp do not limit the optical fiber clamp.

[0103] Figure 7a The following is a schematic diagram of an exploded display of a fiber card clip provided in an embodiment of the present application. Figure 7a As shown, a fiber-bearing clamp 2 includes: a clamp seat 21, a needle clamp 22, a guide needle 23, a guide rod 24, and a spring 25. Among them, the clamp seat 21. After the guide rod 24 and the spring 25 are matched, one end is clamped in the groove of the clamp seat 21, and the other end is clamped in the groove of the needle clamp 22. The guide rod 24 is fixed in the groove of the clamp seat 21, and the needle clamp 22 is fixed by the elastic force of the spring 25. The groove of the needle clamp 22 is larger than the outer contour diameter of the guide rod 24, so that the needle clamp 22 can swing to a certain extent, and adaptive alignment of at least two pairs of ferrules can be achieved. In other words, each ferrule can adjust its own axial position according to the length and grinding angle of the ferrule that matches it, to ensure that each pair of ferrules can be closely connected and stable signal transmission is guaranteed.

[0104] Figure 7b This is an oblique schematic diagram of a fiber card clip provided in an embodiment of the present application. Figure 7b As shown, the middle of the clamp seat 21 and the needle clamp 22 is provided with aligned grooves, which are used to fix the ribbon fiber body. One end of the guide needle 23 is clamped inside the needle clamp 22 to cooperate with the guide hole of the ribbon fiber to guide and fix the ribbon fiber.

[0105] Figure 7c The present invention provides a schematic diagram of a component assembly including a card seat, a guide rod, and a spring. Figure 7c As shown, a guide rod 24 and a spring 25 are clamped inside the clamping groove of the clamping seat 21. One end of the spring 25 abuts against the bottom surface of the needle clamp 22, and the other end abuts against the inside of the groove of the clamping seat 21, thereby realizing the elastic connection of the needle clamp 22.

[0106] See also Figure 8a, Figure 8b , Figure 8a , Figure 8b A schematic diagram of the structure of a clamp seat is shown. The clamp seat 21 includes a groove to install a guide rod 24 and a spring 25. The clamp seat 21 also includes two first accommodating grooves facing outward to facilitate the disassembly and assembly of the MT fiber. A crossbeam is arranged in the middle of the clamp seat 21, and first accommodating grooves are arranged on both sides of the crossbeam, so that the space between the two ferrules can be reused between the two ferrules, which can ensure the structural strength of the clamp seat 21. Optionally, the clamp seat 21 also includes a clamping wing 211 and a stop buckle 212, so that the clamp seat 21 is installed and positioned on the adapter body 1.

[0107] It should be noted that the number of first accommodating grooves can be set to multiple, so that the integrated clamp seat 21 can realize integrated plugging and unplugging of multiple MT ferrules. The embodiment of the present application takes two first accommodating grooves as an example for exemplary description, but the number of first accommodating grooves is not limited to two.

[0108] For example, Figure 8a As shown, a clamping seat 21 includes a first groove 214, a second groove 215, and a third groove 216. The first groove 214, the second groove 215, and the third groove 216 are connected in sequence, and the diameter of the second groove 215 is smaller than that of the first groove 214, the second groove 215, and the third groove 216. The second groove 215 is used to clamp and fix the guide rod 24, and the guide rod 24 is clamped in the second groove 215. The spring 25 abuts against the bottom of the first groove 214, which can provide a supporting force for the needle clamp 22, thereby fixing the needle clamp 22. In other words, by placing the guide rod 24 and the spring 25 in the first groove 214, the second groove 215, and the third groove 216, the guide rod 24 and the clamping seat 21 can be fixed.

[0109] For example, Figure 8a As shown, the clamp seat 21 further includes two first accommodating grooves 213 facing outwards, so as to facilitate the disassembly and assembly of two ribbon fiber bodies (such as MT ribbon fibers).

[0110] For example, Figure 8b As shown, a crossbeam 219 is arranged in the middle of the clamp seat 21. The crossbeam 219 is the space between the two ferrules, which is reused between the two ferrules to ensure the strength of the mechanism. Referring to the relevant standards for optical fiber active connectors, the clamp needs to provide a clamping force of 7.8N to 11.8N for the optical fiber ferrule body. It has been verified through actual measurements that this solution can bear a force of 30N and can support two pairs of ferrules to be reliably docked at the same time.

[0111] For example, Figure 8bAs shown, the card clamp seat 21 also includes a card wing 211 and a stop buckle 212. The fiber card clamp 2 can be assembled into the adapter body 1 by pushing the bottom surface 217 of the card connector seat. During the pushing process, the guide positioning block 218 guides and positions the card clamp seat 21, so that the installation position of the card clamp seat 21 is accurate and the connection position of the fiber ferrule is accurate, thereby accurately transmitting the signal. After pushing the fiber card clamp 2 to the specified position, the stop buckle 212 locks the fiber card clamp 2. In the embodiment of the present application, the integrated card clamp seat 21 can realize the integrated plugging and unplugging of multiple MT ferrules.

[0112] Optionally, the first groove 214, the second groove 215, and the third groove 216 can be set at four locations, respectively used to fix four guide rods 24 and springs 25, and are respectively set in pairs at the card seat 21. Figure 8a The front and Figure 8b Back side shown.

[0113] See also Fig. 9 , Fig. 9 The schematic diagram of the structure of a guide rod and a spring is shown. The guide rod 24 is provided with a clamping portion, and the guide rod 24 is clamped to the clamp seat 21 and fixed. The spring 25 is an example of an elastic element and is used to achieve independent floating of the MT ferrule.

[0114] For example, Fig. 9 As shown, the guide rod 24 includes: a first column 241, a second column 242, a third column 243, a fourth column 244, and a fifth column 245. Fig. 9 As shown, the guide rod 24 is composed of 5 coaxial cylinders with different diameters. The first cylinder 241 and the second cylinder 242 at the head of the guide rod 24 can be clamped and fixed in the groove of the needle clamp 22, and the third cylinder 243, the fourth cylinder 244, and the fifth cylinder 245 at the tail of the guide rod 24 can be fixed in the first groove 214, the second groove 215, and the third groove 216 of the clamp seat 21 respectively.

[0115] For example, Fig. 9 As shown, the inner diameter of the spring 25 is larger than the second column 242, and the outer diameter is smaller than the first groove 214, so that the spring 25 can be placed in the first groove 214 of the clamping seat 21 after being sleeved with the guide rod 24. It should be noted that when the guide rod 24 is installed on the side of the clamping seat 21 including the clamping wing 211 and the stop buckle 212, the stop buckle 212 is provided with a corresponding escape space. After the spring can be sleeved with the guide rod 24, the guide rod 24 needs to be passed through the escape space at the stop buckle 212, and then the spring 25 and the guide rod 24 are placed in the first groove 214 on this side of the clamping seat 21.

[0116] For example, Fig. 9As shown, after the spring 25 and the guide rod 24 are assembled, they are assembled into the groove of the clamp seat 21. The third column 243 and the fifth column 245 of the guide rod 24 are respectively assembled into the first groove 214 and the third groove 216. The middle slender part of the third column 243 is clamped in the second groove 215, so that the tail of the guide rod can be fixed in the groove of the clamp seat 21.

[0117] See also Fig.10 , Fig.10 A schematic diagram of the assembly display of a needle clamp, a guide needle, and a guide rod is shown. The needle clamp 22 is used to fix the MT ferrule, and the guide needle 22 is used to limit the MT ferrule. The needle clamp 22 can float independently on the clamp seat 21 through the guide rod 24 and the spring 25.

[0118] For example, Fig.10 As shown, a guide needle 22 is fixedly mounted on one side of the needle clamp 22, and a guide rod 24 is fixedly mounted on the other side. The ferrule of the ribbon fiber assembly 3 passes through the guide needle 22 and is fixedly mounted on the needle clamp 22. The first column 241 of the guide rod 24 is placed inside the needle clamp 22, and the second column 242 is fixedly mounted in the groove of the needle clamp 22. Therefore, the needle clamp 22 has a certain position adjustment capability under the action of the spring 25 and the guide rod 24, thereby adjusting the position of the ferrule of the ribbon fiber assembly 3, so that the ribbon fiber assembly 3 and the adapter body 1 are accurately aligned, and the signal transmission is stable and accurate.

[0119] See also Fig.11 , Fig.11 The top and bottom surfaces of the needle clamp 22 are respectively provided with grooves to fix the guide needle 23 and the guide rod 24 .

[0120] For example, Fig.11 As shown, the needle clamp 22 includes a top surface groove 221, a bottom surface groove 222, and a second accommodating groove 223. The position directly in contact with the insert is assumed to be the top surface of the needle clamp 22, and the position directly in contact with the spring 25 is assumed to be the bottom surface of the needle clamp 22. The needle clamp 22 is provided with a top surface groove 221 on the top surface for fixing the guide needle 23; and a bottom surface groove 222 on the bottom surface for fixing the guide rod 24.

[0121] For example, Fig.11 As shown, the first column 241 and the second column 242 of the guide rod 24 can be buckled into the groove 222 at the bottom surface of the metal needle clamp, and the needle clamp 22 and the clamp seat 21 can be connected into one body through the guide rod 24. The bottom surface groove 222 is provided with a larger slot and a smaller slot that are connected. The larger slot is used to pass the first column 241, and the smaller slot is used to clamp the second column 242.

[0122] For example, Fig.11As shown, the needle clamp 22 is provided with a second accommodating groove 223 facing outwards for accommodating the fiber ribbon body.

[0123] See also Fig.12 , Fig.12 The schematic diagram of the structure of a guide needle is shown. The guide needle 23 is provided with a clamping portion. The guide needle 23 is clamped to the needle clamp 22 through the clamping portion.

[0124] For example, Fig.12 As shown, a clamping portion of a guide needle 23 may include a fixing column 231 , a clamping column 232 , a guide needle body 233 , and a guide head 234 .

[0125] For example, Fig.12 As shown, the fixing column 231 and the clamping column 232 of the guide needle 23 can be buckled into the top surface groove 221 of the needle clamp 22. The top surface groove 221 is provided with a larger slot and a smaller slot connected, the larger slot is used to pass the fixing column 231, and the smaller slot is used to clamp the clamping column 232.

[0126] See also Fig.13 , Fig.13 FIG. 2 shows a schematic diagram of the composition of a ribbon fiber assembly. Fig.13 As shown, a ribbon fiber assembly 3, such as a MT ribbon fiber assembly 3, includes: a ribbon fiber body 32 and a ferrule 33. Fig.13 As shown, a guide hole 31 is provided at the position of the ferrule 33 of the fiber ribbon assembly 3. Optionally, two guide holes 31 are provided.

[0127] See also Fig.14 , Fig.14 FIG. 1 shows a schematic diagram of the components of a fiber-optic plug in an oblique direction. Fig.14 As shown, after the guide hole 31 of the insert 33 passes through the guide needle 23 , it is fixed on the top surface of the needle clamp 22 , and the fiber-bearing body 32 is placed in the second accommodating groove 223 of the needle clamp 22 and the first accommodating groove 213 of the clamp seat 21 .

[0128] For example, when assembling the fiber ribbon assembly 3 and the clamp 2, after aligning the two guide pins 23 with the guide holes 31 of the ferrule and inserting them, the fiber ribbon body 32 is placed into the second receiving groove 223 of the pin clamp 22 and the first receiving groove 213 of the clamp seat 21, so that the fiber ribbon assembly 3 and the clamp 2 are assembled together to form the MT fiber ribbon plug 6. When disassembling, the ferrule 33 is taken out of the guide pins 23, and the fiber ribbon body 32 is taken out of the groove of the clamp 2, so that the fiber ribbon assembly 3 is separated from the clamp 2.

[0129] See also Fig.15 , Fig.15 FIG. 2 shows a schematic diagram of the composition of a fiber-optic plug in another oblique direction. Fig.15As shown, the ferrule 33 is fixed to the top surface of the needle clamp 22, and the spring 25 is fixed to the bottom surface of the needle clamp 22. When the MT ribbon fiber plug 6 is installed in the adapter body 1, the ferrule 33 applies a force to the needle clamp 22, and the needle clamp 22 applies a force to the spring 25. The spring 25 is compressed after receiving the force, thereby changing the position of the ferrule 33, so that the ferrule 33 can automatically align with the interface of the adapter body 1, and achieve a better docking function.
