Description

Technical fields:

[0001] This utility model relates to the field of optical communication technology, and specifically to an FC-type optical communication device port RFID digital tag. Background technology:

[0002] In traditional ODN (Optical Distribution Network) networks, the port connection status and relationships of wiring equipment facilities are usually managed by setting tags at the port jumper locations and attaching log sheets to the equipment enclosures or boxes.

[0003] like Figure 1 As shown, it illustrates the structure of FC type fiber optic patch cord plug 101 being patched through FC type coupling connector 102. FC type coupling connector 102 has a circular port 103. The ends of FC type fiber optic patch cord plug 101 are all configured with circular mating portions 104 that mate with the circular port 103. After the circular mating portions 104 of FC type fiber optic patch cord plug 101 are inserted into the circular port 103 at the end of FC type coupling connector 102, optical signal transmission can be realized.

[0004] The FC-type fiber optic patch cord plug 101 is equipped with a first label, and the corresponding FC-type coupling connector 102 is equipped with a second label on its circular port 103 that matches the first label. When in use, the operator needs to pair the FC-type fiber optic patch cord plug 101 with the circular port 103 of the FC-type coupling connector 102 according to the contents displayed on the first and second labels. After confirming that the pairing requirements are met, the FC-type fiber optic patch cord plug 101 and the circular port 103 of the FC-type coupling connector 102 are inserted into each other to ensure that the paired FC-type fiber optic patch cord plug 101 and FC-type coupling connector 102 are not inserted incorrectly.

[0005] Similarly, the FC type fiber optic patch cord plug 101 is paired with the port of the distribution equipment (such as fiber optic distribution frame) by first matching the first tag on the FC type fiber optic patch cord plug 101 with the third tag set at the port of the distribution equipment, and then plugging is performed after successful pairing.

[0006] However, this also leads to some problems in the development of ODN networks, mainly in three aspects:

[0007] (1) Low efficiency: The number of nodes in the FTTx (Fiber To The x) network is huge, and the label information of a large number of node ports relies on manual searching, marking, copying and inventory, which is inefficient.

[0008] (2) High error rate, specifically: the label information on the ports relies on manual marking and copying, and the port information in the network management system is entered and modified manually, resulting in a high error rate. With long-term operation and maintenance, the labels may fall off or fade, leading to chaotic port scheduling and making it impossible to effectively sort out the jumper relationships.

[0009] (3) Management is lagging behind. Specifically, some of the current working methods of FTTx, such as information collection, work order dispatch, site location, and information archiving, need to be completed manually and are decentralized operations, making it difficult to achieve manageable, controllable, unified and efficient management.

[0010] In summary, ODN network service activation processes are complex, port utilization is low, and management is difficult. In an increasingly competitive environment, operators have an urgent need for efficient, stable, and easily managed and maintained ODN networks, leading to the emergence of intelligent ODN solutions.

[0033] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0034] See Figure 2-9 As shown, an FC-type optical communication device port RFID digital tag includes a first digital tag 2 and a second digital tag 4. The first digital tag 2 is installed on an FC-type coupling connector 3 to form an intelligent module; the second digital tag 4 is installed on an FC-type fiber optic patch cord plug 5 to form an intelligent module. When the FC-type fiber optic patch cord plug 5 and the FC-type coupling connector 3 are plugged in, the first digital tag 2 and the second digital tag 4 are paired to achieve unique identification, thereby achieving a permanent pairing connection and supporting the reading and writing of pairing-related data.

[0035] The FC-type coupling connector 3 and the FC-type fiber optic patch cord plug 5 are both standard parts available on the market.

[0036] Specifically, the first digital tag 2 includes a first bracket 21 and a first RFID chip 22 disposed on the first bracket 21. The first bracket 21 is mounted on the FC-type coupling connector 3, and the portion of the first bracket 21 containing the first RFID chip 22 protrudes from back to front from the periphery of the threaded section 31 at the front end of the FC-type coupling connector 3, forming a gap to facilitate the first RFID chip 22 to dock with the second RFID chip 42 in the second digital tag 4 for pairing and identification. The front end of the threaded section 31 is provided with a port 33 for inserting the FC-type fiber optic patch cord plug 5. The second digital tag 4 includes a second bracket 41 and a second RFID chip 42 disposed on the second bracket 41. The second bracket 41 is mounted on the FC-type fiber optic patch cord plug 5. When the FC-type fiber optic patch cord plug 5 is inserted into the port 33 of the FC-type coupling connector 3, the portions of the first bracket 21 and the second bracket 41 are stacked vertically, and the first RFID chip 22 and the second RFID chip 42 pair and identify each other, thereby achieving a permanent pairing connection and supporting the reading and writing of pairing-related data. In this configuration, the portion of the first bracket 21 containing the first RFID chip 22 protrudes from back to front around the threaded section 31 at the front end of the FC-type coupling connector 3, forming a gap. As a result, after the FC-type fiber optic patch cord plug 5 is inserted into the FC-type coupling connector 3, the portion of the second bracket 41 is inserted into this gap, placing the second RFID chip 42 below the first RFID chip 22 and in a positive projection relationship, so that the first RFID chip 22 and the second RFID chip 42 can perform effective pairing and identification. In other words, without altering the existing FTTx equipment architecture, this invention directly installs the first digital tag 2 and the second digital tag 4 onto the FC-type coupling connector 3 and the FC-type fiber optic patch cord plug 5 respectively, providing unique identification. This achieves intelligent and digital management of individual ports. After the FC-type fiber optic patch cord plug 5 and the FC-type coupling connector 3 are plugged in, the first digital tag 2 and the second digital tag 4 perform pairing identification, thereby achieving a permanent pairing connection. It supports reading and writing pairing-related data, eliminating the need for manual searching, marking, copying, and inventorying of plug and port tag information, thus greatly improving efficiency and accuracy. It also avoids problems such as tags falling off or fading, leading to port scheduling chaos and ineffective patching relationships. Through the pairing of the first digital tag 2 and the second digital tag 4, intelligent management of fiber optic plugs and ports can be achieved, enabling manageable, controllable, unified, and efficient operation, meeting the usage requirements of ODN networks. Furthermore, this invention supports the installation of new equipment and can implement intelligent upgrades to existing facilities, offering simplicity, speed, and ease of operation, while significantly reducing installation and operating costs.

[0037] Radio Frequency Identification (RFID) is an automatic identification technology that uses wireless radio frequency for non-contact, two-way data communication. It reads and writes records (electronic tags or RFID cards) using radio frequency to achieve the purpose of identifying targets and exchanging data.

[0038] The first digital tag 2 and the second digital tag 4 mentioned above support reading electronic tag information and writing tag information under controlled conditions.

[0039] The structure of the first digit tag 2 is explained in detail below.

[0040] The first digital tag 2 is installed on the FC type coupling connector 3 by snap-fit ​​fixing, which is very convenient to install and remove, and facilitates maintenance.

[0041] The first bracket 21 is L-shaped and includes a main plate 211 and a fastening part 212 extending downward along the rear end of the main plate 211. The fastening part 212 is fastened and fixed to the rear end of the threaded section 31.

[0042] The fastening part 212 is C-shaped, that is, the fastening part 212 has a groove with a size larger than a semicircle. The fastening part 212 is directly fastened and fixed to the rear end of the threaded section 31. The area of ​​the fastening part 212 covering the outer periphery of the circular step 311 is more than half, so that the fastening part 212 can achieve a stable fastening assembly with the rear end of the threaded section 31.

[0043] To improve the stability of the assembly of the fastening part 212 and the FC-type coupling connector 3, the following design is also made: the rear end of the threaded section 31 is formed with a circular step 311, and correspondingly, the rear side of the inner wall of the fastening part 212 is formed with a stepped groove 203. When the fastening part 212 is directly fastened and fixed to the rear end of the threaded section 31, the stepped groove 203 is fixed to the outer periphery of the circular step 311, and the inner wall of the fastening part 212 is also wrapped around the outer periphery of the rear end of the threaded section 31, thereby achieving double fastening positioning. Its fastening assembly structure is extremely stable and can make the assembly of the fastening part 212 and the FC-type coupling connector 3 more balanced, so that the entire first digital label 2 will not shake or tilt, ensuring the assembly quality of the two.

[0044] The assembly structure of the first bracket 21 and the first RFID chip 22 is as follows:

[0045] The main body plate 211 is provided with a first mounting groove 201. The depth of the first mounting groove 201 is greater than the thickness of the first RFID chip 22. During assembly, the first RFID chip 22 is pasted and fixed to the bottom of the first mounting groove 201 to achieve positioning. Then, by pouring glue into the first mounting groove 201, a first adhesive 202 is formed to encapsulate the first RFID chip 22. At this time, the first adhesive 202 seals the entire first mounting groove 201 and encapsulates and fixes the first RFID chip 22 in the first mounting groove 201, so that the assembly structure of the first bracket 21 and the first RFID chip 22 is extremely stable.

[0046] The FC-type coupling connector 3 has an outwardly protruding mounting plate 32 on its exterior. The mounting plate 32 has multiple countersunk holes 32 for installation. The threaded section 31 has a port 33 for inserting the FC-type fiber optic patch cord plug 5.

[0047] The FC type fiber optic patch cord plug 5 has an internal threaded sleeve 51 for screwing and fixing with the threaded section 31. The second bracket 41 is installed on the internal threaded sleeve 51 and can rotate with the internal threaded sleeve 51.

[0048] Specifically, the second bracket 41 includes a non-enclosed elastic cylinder 411 and a plate 412 formed at the front end of the non-enclosed elastic cylinder 411. The non-enclosed elastic cylinder 411 is sleeved on the internal threaded sleeve 51 and fastened in place. The non-enclosed elastic cylinder 411 has a certain elastic deformation capability, so that when the non-enclosed elastic cylinder 411 is sleeved on the internal threaded sleeve 51, it can clamp and position itself outside the internal threaded sleeve 51, enhancing the stability of the assembly structure. Furthermore, the non-enclosed elastic cylinder 411 is also fastened in place with the internal threaded sleeve 51, thereby ensuring that the entire second digital label 4 is stably installed outside the internal threaded sleeve 51.

[0049] The specific assembly structure of the non-enclosed elastic cylinder 411 and the internal threaded sleeve 51 is as follows:

[0050] A positioning boss 401 is provided on the rear side of the inner wall of the non-enclosed elastic cylinder 411, and a forward-extending buckle arm 402 is formed at the lower end of the non-enclosed elastic cylinder 411. A positioning space is formed between the front end face of the positioning boss 401 and the rear end face of the buckle arm 402. After the internal threaded sleeve 51 is inserted into the positioning space, a fixed assembly is formed. The specific assembly structure is as follows: after the non-enclosed elastic cylinder 411 is fitted onto the internal threaded sleeve 51, the positioning boss 401 abuts against the rear end of the internal threaded sleeve 51, and the buckle body 403 of the buckle arm 402 is engaged and positioned with the front end of the internal threaded sleeve 51 to form a fixed assembly. Since the non-enclosed elastic cylinder 411 itself has a certain elastic deformation capability, the non-enclosed elastic cylinder 411 can form a more stable assembly relationship with the internal threaded sleeve 51.

[0051] The non-enclosed elastic cylinder 411 has a gap 404 distributed along its axial direction and penetrating its front and rear end faces on its lower side, so that the non-enclosed elastic cylinder 411 can expand outward to form a clamping force from the outside to the inside, thereby forming a more stable assembly relationship with the internal threaded sleeve 51.

[0052] The plate 412 is integrally formed on the upper side of the non-enclosed elastic cylinder 411 and protrudes from the end of the non-enclosed elastic cylinder 411. It is convenient to form a vertical stacked distribution with the second support 41 of the second digital tag 4, so that the first RFID chip 22 and the second RFID chip 42 can perform effective pairing and identification.

[0053] In this embodiment, there are two latch arms 402, distributed on both sides of the gap 404. A window 405 is formed between the front end of the non-enclosed elastic cylinder 411, the lower side of the plate 412, and the upper side of the latch arm 402. The internal threaded sleeve 51 is partially exposed in the window 405, allowing the user to grip the internal threaded sleeve 51 through the window, thereby driving the entire FC-type fiber optic patch cord plug 5 to rotate, so that the internal threaded sleeve 51 and the threaded section 31 are screwed together for easy assembly. The outer surface of the internal threaded sleeve 51 is provided with anti-slip ridges 511 extending along its length. When the user grips the internal threaded sleeve 51 through the window, they will come into contact with the anti-slip ridges 511, which allows the user to apply more force to drive the internal threaded sleeve 51 to rotate, facilitating operation. In addition, the inner wall of the buckle arm 402 and / or the inner wall of the non-enclosed elastic cylinder 411 are provided with a limiting groove 406 that is adapted to the anti-slip ridge 511. The anti-slip ridge 511 is embedded in the limiting groove 406, so that the second digital tag 4 can form a stable assembly with the inner threaded sleeve 51 and can achieve synchronous rotation. When the user can pinch the inner threaded sleeve 51 through the window, the fingers partially contact the second digital tag 4, which can also increase the auxiliary force, thereby driving the FC type fiber optic patch cord plug 5 to rotate.

[0054] A second mounting groove 407 is provided on the plate 412. The depth of the second mounting groove 407 is greater than the thickness of the second RFID chip 42. The second RFID chip 42 is adhered and fixed in the second mounting groove 407. A second adhesive 408 is formed by filling the second mounting groove 407 with glue to encapsulate the second RFID chip 42. At this time, the second adhesive 408 seals the entire second mounting groove 407 and encapsulates and fixes the second RFID chip 42 in the second mounting groove 407, resulting in an extremely stable assembly structure between the second bracket 41 and the second RFID chip 42.

[0055] In some instance methods, combined Figure 10As shown, multiple FC-type coupling connectors 3 can be installed side by side (horizontally or vertically in an array) on the front end of the fiber optic patch panel 6, and the first digital label 2 installed on each FC-type coupling connector 3 is prominently displayed on the front end of the fiber optic patch panel 6 to form a multi-port fiber optic patch panel 6, which is convenient to use and facilitates the unique identification of the FC-type fiber optic patch cord plug 5, thereby achieving the requirements of intelligent and digital management of a single port.

[0056] In summary, this invention, without altering the existing FTTx equipment architecture, directly installs the first digital tag 2 and the second digital tag 4 onto the FC-type coupling connector 3 and the FC-type fiber optic patch cord plug 5 respectively, providing unique identification. This achieves intelligent and digital management of individual ports. After the FC-type fiber optic patch cord plug 5 and the FC-type coupling connector 3 are plugged in, the first digital tag 2 and the second digital tag 4 perform pairing identification, thus achieving a permanent pairing connection. It supports reading and writing pairing-related data, eliminating the need for manual searching, marking, copying, and inventorying of plug and port tag information, significantly improving efficiency and accuracy. It also avoids issues such as tags falling off or fading, leading to port scheduling chaos and ineffective patching relationships. The pairing of the first digital tag 2 and the second digital tag 4 enables intelligent management of fiber optic plugs and ports, achieving manageable, controllable, unified, and efficient operation, meeting the needs of ODN networks. Furthermore, this invention supports the installation of new equipment and can implement intelligent upgrades to existing facilities, offering simplicity, speed, and ease of operation, while significantly reducing installation and operating costs.
