Description

Technical Field

[0001] This application relates to the field of optical communication access network equipment technology, specifically to an optical fiber connector, an optical fiber adapter, and an optical fiber connector assembly. Background Technology

[0002] With the accelerating global digital transformation, FTTH (Fiber To The Home) network construction is rapidly gaining popularity across continents. To improve deployment efficiency and lower construction barriers, pre-connected products, with their plug-and-play, rapid construction, and quick activation advantages, have become the mainstream technology and are widely used in indoor and outdoor scenarios.

[0003] Against this backdrop, a large number of physical resources in traditional ODN (Optical Distribution Network) are referred to as "dumb resources," lacking effective digital identification and dynamic management capabilities. To achieve refined and visualized control over ODN resources, digital ODN is becoming the core trend in the development of next-generation ODN, and many leading domestic and international telecommunications companies have already begun related technology deployments and market promotions.

[0004] Currently, the main goals of digital ODN are to achieve three major functions: first, visualized management of ODN resources; second, automatic construction of fiber optic link topology; and third, intelligent early warning of fiber optic faults. To achieve these goals, the industry has proposed various technical approaches. Among these technologies, one mainstream solution is to use image recognition technology. This involves taking pictures of fiber optic ports and cable tags, and using image comparison to identify the unique ID of the product, thereby achieving a mapping and binding between physical resources and the digital system. However, this method is limited by factors such as ambient lighting conditions, dirt on equipment surfaces, and shooting angle deviations, resulting in unstable recognition accuracy and low operational efficiency.

[0029] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0030] Among related technologies, one solution for digital ODN is to use image recognition technology, but this solution is highly dependent on the external environment. Another solution is to embed RFID (Radio Frequency Identification) tags in ODN equipment (such as fiber optic distribution boxes and optical cables) and write the product's unique ID into the chip, completing resource binding by reading the RFID information. While this solution overcomes the dependence of image recognition on the external environment to some extent and improves recognition stability, it still has significant limitations: it cannot assign a unique identifier to each fiber optic port. Especially in outdoor pre-connection scenarios, typical fiber optic distribution boxes or terminal boxes usually contain multiple fiber optic ports, and existing RFID is mostly integrated into the box body or trunk optical cable level, making it difficult to accurately match the connection relationship between a specific port and the corresponding branch optical cable, resulting in the inability to achieve end-to-end fine-grained resource binding and topology restoration.

[0031] Furthermore, with the widespread application of pre-connected products, especially the gradual replacement of traditional fusion splicing methods by outdoor connectors with waterproof and weather-resistant properties, higher requirements are placed on the functional integration of connector components. How to achieve identifiable identity, traceable status, and automatic topology construction for each fiber optic connection point without increasing construction complexity has become a key bottleneck restricting the comprehensive implementation of digital ODN.

[0032] This application provides an optical fiber connector, an optical fiber adapter, and an optical fiber connector assembly, which can solve the technical problems of unstable identification accuracy and low operation and maintenance efficiency in related technologies.

[0033] See Figure 3 , Figure 4 and Figure 5 As shown, this application embodiment provides an optical fiber connector, which includes: a connector body 31, the connector body 31 having a first micro cavity 311, the first micro cavity 311 having an embedded radio frequency identification (RFID) light-emitting module 4 or an RFID photosensitive module 5; the RFID light-emitting module 4 is configured to be driven to light up using radio frequency induction energy, and the RFID photosensitive module 5 is configured to receive light signals and then be powered, so that the RFID photosensitive module 5 can be identified by an external radio frequency induction device.

[0034] See Figure 4As shown, a first micro-cavity 311 is provided near the front end of the connector body 31. Either a radio frequency identification (RFID) light-emitting module 4 or an RFID photosensitive module 5 can be embedded in this first micro-cavity 311. When the RFID light-emitting module 4 is provided on the fiber optic connector 3, the RFID photosensitive module 5 is provided on the fiber optic adapter 2; conversely, when the RFID photosensitive module 5 is provided on the fiber optic connector 3, the RFID light-emitting module 4 is provided on the fiber optic adapter 2. This arrangement of the RFID light-emitting module 4 on the fiber optic connector 3 is not shown in the figure. The following embodiments mainly describe embodiments where the fiber optic connector 3 has the RFID photosensitive module 5 and the fiber optic adapter 2 has the RFID light-emitting module 4.

[0035] It should be understood that the fiber optic adapter 2 is generally installed in each port of the housing 1, and the fiber optic connector 3 is inserted into the fiber optic adapter 2, so that each port can identify which optical cable 33 is connected to through the fiber optic connector 3 and the radio frequency identification light-emitting module 4 and the radio frequency identification photosensitive module 5 on the fiber optic adapter 2.

[0036] It should be understood that in this embodiment, the RFID light-emitting module 4 can be driven to light up using RFID sensing energy, and the RFID photosensitive module 5 can be activated after receiving the light signal. Then, the external RFID sensing device can read the activated RFID photosensitive module 5. Each RFID light-emitting module 4 and each RFID photosensitive module 5 can have a unique digital identity, supporting precise matching. The external RFID sensing device can obtain the identity information of the fiber optic connector 3 by reading the information, and complete the automatic binding of the port to the optical cable 33 (patch cord, pigtail).

[0037] This embodiment sets a first micro-cavity 311 on the connector body 31, and embeds an RFID light-emitting module 4 or an RFID photosensitive module 5 in the first micro-cavity 311. When the RFID light-emitting module 4 is embedded, it can be driven to light up by RFID sensing energy. When the RFID photosensitive module 5 is embedded, it can receive the light signal emitted by the RFID light-emitting module 4, thereby powering the RFID photosensitive module 5 and enabling external RFID sensing devices to identify the RFID photosensitive module 5. This achieves port-level fine identification without the need for identification by taking pictures, solving the technical problems of unstable identification accuracy and low maintenance efficiency in related technologies.

[0038] Preferably, in the above embodiment, the RFID light-emitting module 4 includes a second passive RFID (Radio Frequency Identification) chip 41, a second antenna, and a light-emitting element 42; the RFID photosensitive module 5 includes a first passive RFID chip 51, a first antenna, and a photosensitive element 52. In this embodiment, the light-emitting element 42 can be, for example, an LED, or other light-emitting elements, and is not limited thereto. The photosensitive element 52 can be, for example, a photodiode. In this embodiment, the light-emitting element 42 is driven to light up by the second passive RFID chip 41 on the fiber optic adapter 2 side using radio frequency induction energy, and the photosensitive element 52 generates a microcurrent after receiving the light signal, activating the first passive RFID chip 51 on the fiber optic connector 3 side. The external radio frequency sensing device can then read the identity information of the fiber optic connector 3 (optical cable 33 end) and complete the automatic binding of the port to the optical cable 33 (patch cord, pigtail). In this embodiment, both the second antenna and the first antenna are flexible antennas.

[0039] Furthermore, in one embodiment, the RFID light-emitting module 4 and the RFID photosensitive module 5 store unique ID codes. In this embodiment, the unique ID codes can be stored in the first passive RFID chip 51 and the second passive RFID chip 41, so that each fiber optic connector 3 and fiber optic adapter 2 has a unique digital identity, supporting accurate matching.

[0040] Furthermore, in one embodiment, the connector body 31 has a mating surface 312, and the connector body 31 is further provided with a fixing claw 313 protruding axially from the mating surface 312. The first micro-cavity 311 is formed in the fixing claw 313 and penetrates the fixing claw 313 radially. See also Figure 5 and Figure 12 As shown, in this embodiment, the connector body 31 has a mating surface 312 at its front end that mates with the adapter body 21. The front end of the connector body 31 also has two fixing claws 313 extending forward from the mating surface 312. The two fixing claws 313 are symmetrically arranged about the axis of the connector body 31. One fixing claw 313 has a first micro-cavity 311 on it, and the RFID photosensitive module 5 is mounted in this first micro-cavity 311. In this embodiment, the fixing claw 313 is provided to provide space for mounting the RFID photosensitive module 5. Furthermore, in this embodiment, the first micro-cavity 311 radially penetrates the fixing claw 313. The first micro-cavity 311 on the fixing claw 313 not only exposes the photosensitive element 52, allowing it to receive light emitted by the light-emitting element 42, but also, during mold design and injection molding, the first micro-cavity 311, through its cooperation with the mold, effectively protects the first passive RFID chip 51 and the photosensitive element 52 from the high temperature of the molten plastic.

[0041] In other embodiments, the connector body 31 may have one fixing claw 313, or even three or four fixing claws 313, which can be designed according to actual needs.

[0042] Furthermore, in one embodiment, the connector body 31 is further provided with a locking part 314, which is used to lock with the adapter body 21. A sealing ring 32 is provided between the locking part 314 and the first micro cavity 311. In this embodiment, the locking part 314 on the outside of the connector body 31 is an external thread, while the adapter body 21 is provided with an internal thread. The connector body 31 and the adapter body 21 are locked together by the internal and external threads. In other embodiments, the connector body 31 and the adapter body 21 can also be locked together in other ways, such as by a latch or a spring-loaded latch. See also Figure 4 and Figure 11 As shown, a sealing ring 32 is also provided on the outside of the connector body 31. The sealing ring 32 is preferably an O-ring, and it is disposed between the locking part 314 and the first micro cavity 311. When the connector body 31 is inserted into the adapter body 21 and locked by the locking part 314, the sealing ring 32 can seal the joint between the connector body 31 and the adapter body 21, preventing water, dust, or light from entering the interior of the adapter body 21 from this position, thus providing a sealed space for the RFID light-emitting module 4 and the RFID photosensitive module 5. In this embodiment, the fiber optic connector 3 also includes an optical cable 33, and the aforementioned locking part 314 is a locking nut.

[0043] In other embodiments, the sealing ring 32 may also be integrally formed with the connector body 31, and may be a raised ring.

[0044] Furthermore, in some optional embodiments, the RFID photosensitive module 5 includes a first fixed body 53, on which a first passive RFID chip 51 and a photosensitive element 52 are fixed; the first fixed body 53 is located inside the first micro cavity 311, and the RFID photosensitive module 5 is fixed to the connector body 31 by injection molding. In this embodiment, the connector body 31 and the RFID photosensitive module 5 are preferably combined using an integrated injection molding process (in other embodiments, they can also be fixed by other means such as embedding). A first micro-cavity 311 is provided at the front end of the connector body 31. The opening direction of the first micro-cavity 311 is radial, and the radial depth of the first micro-cavity 311 is <1.2mm. The first passive RFID chip 51 and the photosensitive element 52 of the RFID photosensitive module 5 are located in the first micro-cavity 311. The first micro-cavity 311 can provide arrangement space for the first passive RFID chip 51 and the photosensitive element 52, and ensure that the photosensitive element 52 can effectively receive the light source. In addition, the first micro-cavity 311 can provide a mold insert sealing space 34 during the integrated injection molding process, thereby protecting the first passive RFID chip 51 and the photosensitive element 52 from damage by the high-temperature plastic melt during the injection molding process.

[0045] Furthermore, in this embodiment, a mold insert sealing space 34 is formed between the first passive RFID chip 51 and the photosensitive element 52 and the inner wall of the first micro-cavity 311. See also Figure 15 As shown, the first passive RFID chip 51 and the photosensitive element 52 can be spaced a certain distance from the inner wall of the first micro cavity 311 to form a mold insert sealing space 34. During injection molding, the mold insert 6 can be inserted into the mold insert sealing space 34 to isolate the first passive RFID chip 51 and the photosensitive element 52 from the plastic melt, protecting the first passive RFID chip 51 and the photosensitive element 52 from damage by the high temperature plastic melt during the injection molding process.

[0046] See Figure 7 and Figure 8As shown in the illustration, this application also provides an optical fiber adapter for use with the aforementioned optical fiber connector. The adapter includes an adapter body 21, which has a second micro-cavity 212. The second micro-cavity 212 is embedded with either a radio frequency identification (RFID) photosensitive module 5 or an RFID light-emitting module 4. When the first micro-cavity 311 of the connector body 31 is embedded with the RFID light-emitting module 4, the second micro-cavity 212 of the adapter body 21 is also embedded with the RFID photosensitive module 5; when the first micro-cavity 311 of the connector body 31 is embedded with the RFID photosensitive module 5, the second micro-cavity 212 of the adapter body 21 is also embedded with the RFID light-emitting module 4. When the RFID light-emitting module 4 is illuminated by radio frequency sensing energy, the RFID photosensitive module 5 can be activated by light triggering.

[0047] It should be understood that the fiber optic adapter 2 in this embodiment can be adapted to the fiber optic connector 3 in any of the above embodiments and achieve the corresponding functions.

[0048] See Figure 7 and Figure 8 As shown, in this embodiment, the fiber optic adapter 2 includes an adapter body 21, which is installed in the housing 1. The adapter body 21 has a plug-in cavity 211 for the fiber optic connector 3 to be inserted. The RFID light-emitting module 4 or the RFID photosensitive module 5 can be embedded and assembled with the adapter body 21. At the same time, a second micro cavity 212 is provided at the tail end of the adapter body 21. The second micro cavity 212 communicates with the plug-in cavity 211. The opening direction of the second micro cavity 212 is radial, and the radial depth of the second micro cavity 212 is <1.2mm. When the RFID light-emitting module 4 is installed in the second micro cavity 212, the second passive RFID chip 41 and the light-emitting element 42 of the RFID light-emitting module 4 are located in the second micro cavity 212. By setting the second micro cavity 212 on the adapter body 21, not only is space provided for the arrangement of the second passive RFID chip 41 and the light-emitting element 42, but also the light energy emitted by the light-emitting element 42 is effectively transmitted.

[0049] Further, in one embodiment, the adapter body 21 is provided with a first stop arm 213 and a second stop arm 214 distributed radially. The first stop arm 213 and the second stop arm 214 are distributed on the same side of the axis of the adapter body 21, and a second micro cavity 212 is formed between the first stop arm 213 and the second stop arm 214. The second stop arm 214 has a through hole 215, which communicates with the insertion cavity 211. The RFID light-emitting module 4 includes a light-emitting element 42, which is exposed in the through hole 215. See also Figure 13As shown, in this embodiment, the first stop arm 213 and the second stop arm 214 are radially spaced, forming a second micro-cavity 212 between them. The first stop arm 213 and the second stop arm 214 are located on the same side of the axis of the adapter body 21. The RFID light-emitting module 4 is mounted between the first stop arm 213 and the second stop arm 214, which can limit the RFID light-emitting module 4 in both radial and circumferential directions. Simultaneously, a through hole 215 radially penetrates the second stop arm 214, allowing the through hole 215 to connect to the insertion cavity 211 inside the adapter body 21. The light-emitting element 42 is exposed in this through hole 215, thus exposing the light-emitting element 42. Figure 14 As shown in the figure, the light emitted by the light-emitting element 42 can be radially directed into the insertion cavity 211, and the light emission angle is more concentrated, ensuring that the photosensitive element 52 can receive the light emitted by the light-emitting element 42.

[0050] Further, in some optional embodiments, the RFID light-emitting module 4 includes a second fixed body 43, on which a second passive RFID chip 41 and a light-emitting element 42 are fixedly mounted; the second fixed body 43 is embedded in the second micro-cavity 212, and a portion of the second micro-cavity 212 radially penetrates the first stop arm 213 and axially penetrates one end face of the adapter body 21 to form a slot 216, in which the second fixed body 43 is exposed. See also Figure 13 As shown, in this embodiment, the first stop arm 213 is not flush with the second stop arm 214, but a slot 216 is opened at the rear end of the first stop arm 213. The slot 216 also penetrates the adapter body 21 radially and axially. By setting the slot 216, it is convenient to assemble the radio frequency identification light-emitting module 4 between the first stop arm 213 and the second stop arm 214. The second micro cavity 212 penetrates the adapter body 21 radially rearward between the first stop arm 213 and the second stop arm 214, but does not penetrate the adapter body 21 forward, which is a blind hole structure. This allows the front end of the second micro cavity 212 to perform a certain axial limitation on the second fixed body 43.

[0051] See Figure 13 As shown, in the above embodiment, the rear end of the adapter body 21 is also provided with a guide slope 219, which is used to assemble the second fixed body 43, and can reduce the assembly difficulty of the second fixed body 43 to a certain extent.

[0052] Furthermore, in one embodiment, the second fixing body 43 is provided with an axial limiting structure 431, and the adapter body 21 is provided with a limiting part 217 on one side of the slot 216, the limiting part 217 cooperating with the axial limiting structure 431 for limiting. See also Figure 9 and Figure 13As shown, in this embodiment, the axial limiting structure 431 on the second fixed body 43 is a protrusion, and the limiting part 217 on the adapter body 21 is a groove structure. The axial limiting structure 431 enters the limiting part 217 for axial limiting. In other embodiments, the axial limiting structure 431 can also be a groove structure, and the limiting part 217 can be a protrusion.

[0053] Preferably, in this embodiment, the adapter body 21 is provided with a sealing gasket 22, which is sandwiched between the adapter body 21 and the housing 1 during use. See also Figure 11 As shown, the adapter body 21 is also provided with external threads, so that the adapter body 21 and the housing 1 are connected by threads; at the same time, the adapter body 21 is also provided with a boss 218, and the sealing gasket 22 is located on the rear side of the boss 218. When the adapter body 21 is assembled into the housing 1, the sealing gasket 22 is sandwiched between the housing 1 and the boss 218 to seal the joint position of the adapter body 21 and the housing 1, preventing water, dust or light from entering the interior of the housing 1 from this position, and providing a sealed space for the RFID light-emitting module 4 and the RFID photosensitive module 5.

[0054] This application also provides an optical fiber connector assembly, which includes the optical fiber connector 3 and the optical fiber adapter 2 described above. The optical fiber connector 3 in this embodiment can be any of the optical fiber connectors described above, and will achieve the corresponding functions; and the optical fiber adapter 2 can be any of the optical fiber adapters described above, and will achieve the corresponding functions.

[0055] Furthermore, in one embodiment, the fiber optic connector assembly further includes a housing 1, wherein the housing 1 is provided with at least one of the fiber optic adapters 2. See also Figure 1 and Figure 2 As shown, in this embodiment, the housing 1 includes a cavity 11 and a bottom 12. Multiple fiber optic adapters 2 can be mounted on the cavity 11. Each fiber optic adapter 2 is equipped with a radio frequency identification (RFID) light-emitting module 4, and each fiber optic adapter 2 can be plugged into a fiber optic connector 3 outside the housing 1. Each fiber optic connector 3 is equipped with an RFID photosensitive module 5. This embodiment can also be reversed, that is, an RFID light-emitting module 4 is provided on each fiber optic connector 3, and an RFID photosensitive module 5 is provided on each fiber optic adapter 2. This arrangement is not shown in the figure. The following embodiments mainly describe embodiments where the fiber optic connector 3 is equipped with an RFID photosensitive module 5 and the fiber optic adapter 2 is equipped with an RFID light-emitting module 4.

[0056] It should be understood that in this embodiment, the RFID light-emitting module 4 can be driven to light up using RFID sensing energy, and the RFID photosensitive module 5 can be activated after receiving the light signal. Then, the external RFID sensing device can read the activated RFID photosensitive module 5. Each RFID light-emitting module 4 and each RFID photosensitive module 5 can have a unique digital identity, supporting precise matching. The external RFID sensing device can obtain the identity information of the fiber optic connector 3 by reading the information, and complete the automatic binding of the port to the optical cable 33 (patch cord, pigtail).

[0057] Preferably, when the fiber optic connector 3 is inserted into the fiber optic adapter 2, the fiber optic connector 3, the fiber optic adapter 2, and the housing 1 together form a sealed space, and the radio frequency identification light-emitting module 4 and the radio frequency identification photosensitive module 5 are located within the sealed space.

[0058] This embodiment sets up an RFID light-emitting module 4 on the fiber optic adapter 2 and an RFID photosensitive module 5 on the fiber optic connector 3. The RFID light-emitting module 4 can be driven to light up by radio frequency induction energy. When the fiber optic connector 3 is inserted into the fiber optic adapter 2 and the RFID light-emitting module 4 is lit, the RFID photosensitive module 5 on the fiber optic connector 3 inserted into the fiber optic adapter 2 is activated. The activated RFID photosensitive module 5 can be identified by an external radio frequency sensing device. By reading the ID of the RFID photosensitive module 5, the identity information of the fiber optic connector 3 can be obtained, realizing port-level fine-grained identification and realizing an automated identification mechanism of "physical connection is logical registration", which improves the intelligence level of the ODN network. Furthermore, after the fiber optic connector 3 is inserted into the fiber optic adapter 2, the RFID light-emitting module 4 and the RFID photosensitive module 5 are located in a closed space and are not affected by factors such as ambient light conditions, dirt on the equipment surface, and shooting angle deviation. All electronic components can operate stably for a long time in harsh environments such as high temperature, high humidity, salt spray, and ultraviolet radiation, resulting in high operation and maintenance efficiency. This solves the technical problems of unstable identification accuracy and low operation and maintenance efficiency in related technologies.

[0059] Meanwhile, the fiber optic connector assembly provided in this application operates entirely based on a passive RFID and optical triggering mechanism, resulting in extremely low power consumption and maintenance-free operation. It reliably activates and identifies the RFID photosensitive module 5 at the 33-end of the optical cable without requiring external power. Multiple fiber optic adapters 2 mounted on the housing 1 can be simultaneously scanned by a PDA (Personal Digital Assistant; in some scenarios, PDA also refers to handheld terminal devices with RFID identification capabilities, commonly used in logistics, warehousing, and asset management) or a fixed reader / writer, improving operational efficiency. It also provides underlying data support for more refined resource inventory, construction quality inspection, and fault location, promoting the construction of intelligent ODN.

[0060] Preferably, in the above embodiment, the RFID light-emitting module 4 includes a second passive RFID (Radio Frequency Identification) chip 41, a second antenna, and a light-emitting element 42; the RFID photosensitive module 5 includes a first passive RFID chip 51, a first antenna, and a photosensitive element 52. In this embodiment, the light-emitting element 42 can be, for example, an LED, or other light-emitting elements, and is not limited thereto. The photosensitive element 52 can be, for example, a photodiode. In this embodiment, the light-emitting element 42 is driven to light up by the second passive RFID chip 41 on the fiber optic adapter 2 side using radio frequency induction energy, and the photosensitive element 52 generates a microcurrent after receiving the light signal, activating the first passive RFID chip 51 on the fiber optic connector 3 side. The external radio frequency sensing device can then read the identity information of the fiber optic connector 3 (optical cable 33 end) and complete the automatic binding of the port to the optical cable 33 (patch cord, pigtail). In this embodiment, both the second antenna and the first antenna are flexible antennas.

[0061] Furthermore, in one embodiment, the RFID light-emitting module 4 may further include a second fixed body 43, with the second passive RFID chip 41 and the light-emitting element 42 fixed to the second fixed body 43. The second passive RFID chip 41 and the light-emitting element 42 can be fixed to the fiber optic adapter 2 through the second fixed body 43; see also Figure 6 As shown, the RFID photosensitive module 5 may also include a first fixed body 53, a first passive RFID chip 51 and a photosensitive element 52 fixed on the first fixed body 53, and the first passive RFID chip 51 and the photosensitive element 52 can be fixed to the fiber optic connector 3 through the first fixed body 53.

[0062] Furthermore, in some embodiments, the fiber optic adapter 2 includes an adapter body 21, the adapter body 21 having a plug cavity 211, and the adapter body 21 having a second micro cavity 212 communicating with the plug cavity 211, the radio frequency identification light-emitting module 4 being embedded in the second micro cavity 212; the fiber optic connector 3 includes a connector body 31, the connector body 31 having a first micro cavity 311, the radio frequency identification photosensitive module 5 being embedded in the first micro cavity 311.

[0063] See Figure 7 and Figure 8As shown, in this embodiment, the fiber optic adapter 2 includes an adapter body 21, which is installed in the housing 1. The adapter body 21 has a plug-in cavity 211 for the fiber optic connector 3 to be plugged in. The radio frequency identification (RFID) light-emitting module 4 can be embedded and assembled with the adapter body 21. At the same time, a second micro cavity 212 is provided at the tail end of the adapter body 21. The opening direction of the second micro cavity 212 is radial, and the radial depth of the second micro cavity 212 is <1.2mm. The second passive RFID chip 41 and the light-emitting element 42 of the RFID light-emitting module 4 are located in the second micro cavity 212. By setting the second micro cavity 212 on the adapter body 21, not only is space provided for the arrangement of the second passive RFID chip 41 and the light-emitting element 42, but the light energy emitted by the light-emitting element 42 is also effectively transmitted.

[0064] Also see Figure 4 and Figure 5 As shown, in this embodiment, the connector body 31 and the RFID photosensitive module 5 are preferably combined using an integrated injection molding process (in other embodiments, other methods, such as embedding, can also be used to fix the two together). A first micro-cavity 311 is provided at the front end of the connector body 31. The opening direction of the first micro-cavity 311 is radial, and the radial depth of the first micro-cavity 311 is <1.2mm. The first passive RFID chip 51 and the photosensitive element 52 of the RFID photosensitive module 5 are located in the first micro-cavity 311. The first micro-cavity 311 can provide arrangement space for the first passive RFID chip 51 and the photosensitive element 52, and ensure that the photosensitive element 52 can effectively receive the light source. Furthermore, the first micro-cavity 311 can provide a mold insert sealing space 34 during the integrated injection molding process, thereby protecting the first passive RFID chip 51 and the photosensitive element 52 from damage by the high-temperature plastic melt during the injection molding process.

[0065] This embodiment, by setting a second micro-cavity 212 in the adapter body 21 to house the RFID light-emitting module 4, and setting a first micro-cavity 311 in the connector body 31 to house the RFID photosensitive module 5, enables the RFID light-emitting module 4 and the RFID photosensitive module 5 to be embedded in the pre-connected fiber optic adapter 2 and fiber optic connector 3 within a limited space. This allows the fiber optic connector 3 and fiber optic adapter 2 to accommodate the RFID light-emitting module 4 and the RFID photosensitive module 5 without changing the external dimensions of the LC / SC standard interface, and can directly replace existing standard connectors and adapters. It maintains the ease of installation of the pre-connected product, does not change the original interface standard, and supports unique identification and data reading for each connection point, achieving a miniaturized, highly reliable, and interconnected identification structural design. This addresses the shortcomings of existing image recognition and RFID technologies in port-level resource management, thereby promoting ODN resource management towards true end-to-end digitalization and intelligence.

[0066] Furthermore, in one embodiment, the connector body 31 has a mating surface 312, and the connector body 31 is further provided with a fixing claw 313 protruding axially from the mating surface 312. The first micro-cavity 311 is formed in the fixing claw 313 and penetrates the fixing claw 313 radially. See also Figure 5 and Figure 12 As shown, in this embodiment, the connector body 31 has a mating surface 312 at its front end that mates with the adapter body 21. The front end of the connector body 31 also has two fixing claws 313 extending forward from the mating surface 312. The two fixing claws 313 are symmetrically arranged about the axis of the connector body 31. One fixing claw 313 has a first micro-cavity 311 on it, and the RFID photosensitive module 5 is mounted in this first micro-cavity 311. In this embodiment, the fixing claw 313 is provided to provide space for mounting the RFID photosensitive module 5. Furthermore, in this embodiment, the first micro-cavity 311 radially penetrates the fixing claw 313. The first micro-cavity 311 on the fixing claw 313 not only exposes the photosensitive element 52, allowing it to receive light emitted by the light-emitting element 42, but also, during mold design and injection molding, the first micro-cavity 311, through its cooperation with the mold, effectively protects the first passive RFID chip 51 and the photosensitive element 52 from the high temperature of the molten plastic.

[0067] In other embodiments, the connector body 31 may have one fixing claw 313, or even three or four fixing claws 313, which can be designed according to actual needs.

[0068] Furthermore, in one embodiment, the connector body 31 is further provided with a locking part 314, which is used to lock with the adapter body 21. A sealing ring 32 is provided between the locking part 314 and the first micro cavity 311. In this embodiment, the locking part 314 on the outside of the connector body 31 is an external thread, while the adapter body 21 is provided with an internal thread. The connector body 31 and the adapter body 21 are locked together by the internal and external threads. In other embodiments, the connector body 31 and the adapter body 21 can also be locked together in other ways, such as by a latch or a spring-loaded latch. See also Figure 4 and Figure 11As shown, a sealing ring 32 is also provided on the outside of the connector body 31. The sealing ring 32 is preferably an O-ring, and it is disposed between the locking part 314 and the first micro cavity 311. When the connector body 31 is inserted into the adapter body 21 and locked by the locking part 314, the sealing ring 32 can seal the joint between the connector body 31 and the adapter body 21, preventing water, dust, or light from entering the interior of the adapter body 21 from this position, thus providing a sealed space for the RFID light-emitting module 4 and the RFID photosensitive module 5. In this embodiment, the fiber optic connector 3 also includes an optical cable 33, and the aforementioned locking part 314 is a locking nut.

[0069] In other embodiments, the sealing ring 32 may also be integrally formed with the connector body 31, and may be a raised ring.

[0070] Further, in one embodiment, the adapter body 21 is provided with a first stop arm 213 and a second stop arm 214 distributed radially. The first stop arm 213 and the second stop arm 214 are distributed on the same side of the axis of the adapter body 21, and a second micro cavity 212 is formed between the first stop arm 213 and the second stop arm 214. The second stop arm 214 has a through hole 215, which communicates with the insertion cavity 211. The RFID light-emitting module 4 includes a light-emitting element 42, which is exposed in the through hole 215. See also Figure 13 As shown, in this embodiment, the first stop arm 213 and the second stop arm 214 are radially spaced, forming a second micro-cavity 212 between them. The first stop arm 213 and the second stop arm 214 are located on the same side of the axis of the adapter body 21. The RFID light-emitting module 4 is mounted between the first stop arm 213 and the second stop arm 214, which can limit the RFID light-emitting module 4 in both radial and circumferential directions. Simultaneously, a through hole 215 radially penetrates the second stop arm 214, allowing the through hole 215 to connect to the insertion cavity 211 inside the adapter body 21. The light-emitting element 42 is exposed in this through hole 215, thus exposing the light-emitting element 42. Figure 14 As shown in the figure, the light emitted by the light-emitting element 42 can be radially directed into the insertion cavity 211, and the light emission angle is more concentrated, ensuring that the photosensitive element 52 can receive the light emitted by the light-emitting element 42.

[0071] Further, in some optional embodiments, the RFID light-emitting module 4 includes a second fixed body 43, on which a second passive RFID chip 41 and a light-emitting element 42 are fixedly mounted; the second fixed body 43 is embedded in the second micro-cavity 212, and a portion of the second micro-cavity 212 radially penetrates the first stop arm 213 and axially penetrates one end face of the adapter body 21 to form a slot 216, in which the second fixed body 43 is exposed. See also Figure 13 As shown, in this embodiment, the first stop arm 213 is not flush with the second stop arm 214, but a slot 216 is opened at the rear end of the first stop arm 213. The slot 216 also penetrates the adapter body 21 radially and axially. By setting the slot 216, it is convenient to assemble the radio frequency identification light-emitting module 4 between the first stop arm 213 and the second stop arm 214. The second micro cavity 212 penetrates the adapter body 21 radially rearward between the first stop arm 213 and the second stop arm 214, but does not penetrate the adapter body 21 forward, which is a blind hole structure. This allows the front end of the second micro cavity 212 to perform a certain axial limitation on the second fixed body 43.

[0072] See Figure 13 As shown, in the above embodiment, the rear end of the adapter body 21 is also provided with a guide slope 219, which is used to assemble the second fixed body 43, and can reduce the assembly difficulty of the second fixed body 43 to a certain extent.

[0073] Furthermore, in one embodiment, the second fixing body 43 is provided with an axial limiting structure 431, and the adapter body 21 is provided with a limiting part 217 on one side of the slot 216, the limiting part 217 cooperating with the axial limiting structure 431 for limiting. See also Figure 9 and Figure 13 As shown, in this embodiment, the axial limiting structure 431 on the second fixed body 43 is a protrusion, and the limiting part 217 on the adapter body 21 is a groove structure. The axial limiting structure 431 enters the limiting part 217 for axial limiting. In other embodiments, the axial limiting structure 431 can also be a groove structure, and the limiting part 217 can be a protrusion.

[0074] Preferably, in this embodiment, a sealing gasket 22 is provided on the outside of the adapter body 21, and the sealing gasket 22 is sandwiched between the adapter body 21 and the housing 1. See also Figure 11As shown, the adapter body 21 is also provided with external threads, so that the adapter body 21 and the housing 1 are connected by threads; at the same time, the adapter body 21 is also provided with a boss 218, and the sealing gasket 22 is located on the rear side of the boss 218. When the adapter body 21 is assembled into the housing 1, the sealing gasket 22 is sandwiched between the housing 1 and the boss 218 to seal the joint position of the adapter body 21 and the housing 1, preventing water, dust or light from entering the interior of the housing 1 from this position, and providing a sealed space for the RFID light-emitting module 4 and the RFID photosensitive module 5.

[0075] In this embodiment, when the fiber optic connector 3 is fully inserted into the fiber optic adapter 2, the housing 1, fiber optic connector 3, and fiber optic adapter 2 cooperate to form a sealed cavity. The RFID photosensitive module 5 inside the fiber optic connector 3 and the RFID light-emitting module 4 inside the fiber optic adapter 2 are located within this sealed cavity. Figure 10 (As shown). This sealed space achieves IP68 and a seal through the sealing ring 32 and sealing gasket 22. This sealed cavity prevents moisture and dust from entering. The housing 1 provides protection against high temperature, high humidity, salt spray, and ultraviolet radiation, protecting all internal electronic components. It has high environmental adaptability and is suitable for long-term outdoor deployment. At the same time, this sealed cavity can provide a dark environment, providing a reliable environment for light emission → light sensing, while preventing other light sources (such as natural light and artificial light) from causing false triggering.

[0076] Furthermore, in one embodiment, the RFID photosensitive module 5 includes a first fixed body 53, on which a first passive RFID chip 51 and a photosensitive element 52 are fixed; the first fixed body 53 is located inside the first micro cavity 311, and the RFID photosensitive module 5 is fixed to the connector body 31 by injection molding. In this embodiment, the connector body 31 and the RFID photosensitive module 5 are preferably combined using an integrated injection molding process (in other embodiments, they can also be fixed by other means such as embedding). A first micro-cavity 311 is provided at the front end of the connector body 31. The opening direction of the first micro-cavity 311 is radial, and the radial depth of the first micro-cavity 311 is <1.2mm. The first passive RFID chip 51 and the photosensitive element 52 of the RFID photosensitive module 5 are located in the first micro-cavity 311. The first micro-cavity 311 can provide arrangement space for the first passive RFID chip 51 and the photosensitive element 52, and ensure that the photosensitive element 52 can effectively receive the light source. In addition, the first micro-cavity 311 can provide a mold insert sealing space 34 during the integrated injection molding process, thereby protecting the first passive RFID chip 51 and the photosensitive element 52 from damage by the high-temperature plastic melt during the injection molding process.

[0077] Furthermore, in this embodiment, a mold insert sealing space 34 is formed between the first passive RFID chip 51 and the photosensitive element 52 and the inner wall of the first micro-cavity 311. See also Figure 15 As shown, the first passive RFID chip 51 and the photosensitive element 52 can be spaced a certain distance from the inner wall of the first micro cavity 311 to form a mold insert sealing space 34. During injection molding, the mold insert 6 can be inserted into the mold insert sealing space 34 to isolate the first passive RFID chip 51 and the photosensitive element 52 from the plastic melt, protecting the first passive RFID chip 51 and the photosensitive element 52 from damage by the high temperature plastic melt during the injection molding process.

[0078] Preferred, see Figure 11 As shown, when the fiber optic connector 3 is fully inserted into the fiber optic adapter 2, the RFID light-emitting module 4 and the RFID photosensitive module 5 are radially aligned. In this embodiment, when the fiber optic connector 3 is fully inserted into the fiber optic adapter 2 along the arrow direction (central axis direction), the light-emitting element 42 and the photosensitive element 52 are radially aligned, and the radial distance between them is ≤1mm, ensuring that the light intensity is sufficient to trigger the photosensitive element 52 to conduct. The light-emitting direction of the light-emitting element 42 is perpendicular to the insertion direction of the fiber optic connector 3, and the light-emitting angle is concentrated. In other embodiments, the light-emitting element 42 and the photosensitive element 52 do not necessarily have to be perfectly aligned; a slight deviation along the axial direction is acceptable, as long as the light emitted by the light-emitting element 42 can trigger the photosensitive element 52.

[0079] The fiber optic connector assembly provided in this application is particularly suitable for port-level resource management in scenarios such as outdoor patch panels, splitter boxes, and terminal boxes. Furthermore, this assembly achieves physical linkage identification between the adapter and patch cords / pigeons through structural innovation, possessing a high protection level and long-term operational reliability, and can be used to construct digital connection units in intelligent ODN (Optical Distribution Network) networks.

[0080] This application proposes for the first time an integrated structure of "light-controlled triggering + passive RFID" in the fiber optic connector 3. In related technologies, there is no known design that embeds the LED light-emitting element 42 into the adapter and the photosensitive element 52 into the jumper connector to form a linked identification mechanism. Furthermore, traditional methods only use independent RFID tags attached to the device casing, which cannot achieve port-level bonding. This application, through physical structural design, enables two separate components (adapter and jumper) to form a fully functional identification system at the moment of insertion. Simultaneously, the miniature cavity layout and sealed space construction of this application embodiment are unique. Dedicated miniature cavities are created in the standard LC / SC type fiber optic connector 3 and adapter for embedding electronic modules without affecting insertion / extraction force, alignment accuracy, or mechanical strength. After insertion, the connector, adapter, and housing 1 together form a fully enclosed protective space, within which all sensitive electronic components are located. This application also implements a dual-sided passive power supply logic structure. The jumper-side RFID does not require a battery and relies on the light energy emitted by the LED at the adapter end to drive the photosensitive element 52 to generate a microcurrent to wake up the chip. This energy transfer path of "RF power → optical signal conversion → photoelectric excitation → RFID response" relies on precise spatial alignment and optical path design in structure, which belongs to a brand-new physical layer interaction paradigm.

[0081] This application embodiment achieves deep integration of three technical fields: optical communication connector structural design → miniaturization modification under standard interfaces → achieving high-density integration without affecting performance → passive RFID identification technology → embedded deployment inside the connector → supporting long-distance batch reading of identity information → photoelectric sensing and energy coupling → LED → photosensitive element 52 triggering mechanism → solving the problem of no power supply at the jumper end. It also solves the long-standing problem of "last-centimeter identification": current intelligent ODN systems can manage down to the cabinet and board level, but it is difficult to pinpoint "which jumper is plugged into which port"; the industry has tried methods such as barcode scanning, magnetic induction, and electrical contacts, all of which suffer from wear, contamination, and high costs; this embodiment avoids the risk of physical contact aging through a non-contact light-controlled triggering mechanism while ensuring identification reliability. The structural design brings a functional leap: from "passive connection" to "active sensing": traditional fiber optic connectors are merely signal paths and lack any intelligent attributes; this embodiment, through structural innovation, makes them intelligent nodes with state-aware capabilities; the automated operation and maintenance capabilities of "insertion upon registration" and "disconnection upon alarm" improve the overall digitalization level of the network.
