Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a connection component. Background Art

[0002] With the rapid development and popularization of fiber-optic communications, the number of optical fibers is also increasing day by day. Optical fibers are connected to the fiber-optic adapters of the optical cross-connect box distribution frame through fiber-optic connector plugs. Due to the large number and chaotic lines, the connection relationship between the fiber-optic connector plugs and the fiber-optic adapters is often very difficult to sort out, which brings difficulties to daily maintenance and line modification.

[0003] In the prior art, a small RFID tag is added to each fiber optic adapter and fiber optic connector plug. Each RFID tag stores a unique identifier, and the reading distance of the RFID tag is limited to about 1 cm. When reading, a dedicated RFID reader is used to read at each fiber optic adapter in turn. If only one RFID tag is read, it means that the fiber optic adapter is vacant; if two RFID tags are read, the two RFID tags indicate the fiber optic adapter and the fiber optic connector plug respectively, and the pairing is completed.

[0004] However, in order to prevent cross-reading (reading RFID tags of other optical fiber adapters or optical fiber connector plugs), the above solution needs to limit the reading distance of the RFID tag and reads one optical fiber adapter at a time, which is inefficient. Summary of the invention

[0005] The present application provides a connection component and a connection relationship identification method, which are used to support batch reading of the connection relationship between the optical fiber connector plug and the optical fiber adapter and avoid cross-reading.

[0006] In a first aspect, the present application provides a connection component:

[0007] The invention comprises a first connecting device, a second connecting device, an RFID antenna, an RFID chip and an electronic device. The RFID antenna and the RFID chip are arranged on the first connecting device, and the electronic device is arranged on the second connecting device. When the first connecting device is connected to the second connecting device, the RFID antenna, the RFID chip and the electronic device form an RFID tag, the RFID chip stores identification information, and the identification information is used to identify the first connecting device. The RFID chip can read the electrical parameters of the electronic device, and the electrical parameters are used to identify the second connecting device.

[0008] In the present application, the first connecting device is, for example, a fiber optic connector plug, and the second connecting device is, for example, a fiber optic adapter. Only when the fiber optic connector plug is inserted into the fiber optic adapter can the digital ID and electrical parameters be read by the RFID reader, and based on this, the fiber optic connector plug and the fiber optic adapter connected together can be identified. Moreover, the digital ID and the electrical parameters come from the same RFID tag, and the corresponding relationship can be directly determined, so that batch reading of connection relationships can be achieved to prevent cross-reading.

[0009] In a possible implementation, the first connecting device is a fiber optic connector plug, and the second connecting device is a fiber optic adapter, or the first connecting device is a fiber optic adapter, and the second connecting device is a fiber optic connector plug.

[0010] In a possible implementation, the electronic device is provided with two contacts, and the RFID antenna and the RFID chip are each provided with a contact. When the first connecting device is connected to the second connecting device, the two contacts on the electronic device are in contact with the contacts of the RFID antenna and the RFID chip respectively.

[0013] In the present application, since the RFID antenna is fixedly connected to the RFID chip, even if the fiber optic connector plug is not connected to the fiber optic adapter, the identification information can be read using an RFID reader. If only the identification information can be read but the corresponding electrical parameters cannot be read, it means that the fiber optic connector plug is vacant.

The RFID chip can read the impedance of the RFID antenna, and the impedance is used to identify the first connecting device.

[0017] In the present application, the first connecting device is, for example, a fiber optic connector plug, and the second connecting device is, for example, a fiber optic adapter. By splitting the RFID tag into the fiber optic adapter and the fiber optic connector plug, the digital ID and impedance can only be read by the RFID reader when the fiber optic connector plug is inserted into the fiber optic adapter, and the fiber optic connector plug and the fiber optic adapter connected together can be identified based on this. Moreover, the digital ID and the impedance come from the same RFID tag, and the corresponding relationship can be directly determined, so that batch reading of connection relationships can be achieved to prevent cross-reading.

[0018] In a possible implementation, contacts are provided on the RFID antenna and the RFID chip. When the first connecting device is connected to the second connecting device, the contacts of the RFID antenna and the RFID chip come into contact to form an RFID tag.

[0019] In the present application, the contact point contact method is used to ensure that when the first connecting device is connected to the second connecting device, the RFID antenna is connected to the RFID chip, thereby ensuring the reliability and simplicity of the connection.

[0020] In a possible implementation, the first connecting device is a fiber optic connector plug, and the second connecting device is a fiber optic adapter, or the first connecting device is a fiber optic adapter, and the second connecting device is a fiber optic connector plug.

[0021] The third aspect of the present application provides a connection component:

[0022] The invention comprises a first connecting device, a second connecting device, an RFID antenna, an RFID chip and an electronic device. The RFID antenna and the electronic device are arranged on the first connecting device, and the RFID chip is arranged on the second connecting device.

[0023] In the present application, the first connecting device is, for example, a fiber optic connector plug, and the second connecting device is, for example, a fiber optic adapter. Only when the fiber optic connector plug is inserted into the fiber optic adapter can the digital ID and electrical parameters be read by the RFID reader, and based on this, the fiber optic connector plug and the fiber optic adapter connected together can be identified. Moreover, the digital ID and the electrical parameters come from the same RFID tag, and the corresponding relationship can be directly determined, so that batch reading of connection relationships can be achieved to prevent cross-reading.

[0024] In a possible implementation, the RFID antenna and the electronic device are provided with contacts, and the RFID chip is provided with two contacts. When the first connecting device is connected to the second connecting device, the two contacts of the RFID chip are in contact with the contacts of the RFID antenna and the electronic device respectively.

[0025] In the present application, contact is used to ensure that when the first connecting device is connected to the second connecting device, the RFID chip is connected to the RFID antenna and the electronic device respectively, thereby ensuring the reliability and simplicity of the connection.

[0051] The following describes the embodiments of the present application in conjunction with the accompanying drawings. Obviously, the described embodiments are only embodiments of a part of the present application, rather than all embodiments. It is known to those skilled in the art that with the development of technology and the emergence of new scenarios, the technical solutions provided by the present application are also applicable to similar technical problems.

[0052] The terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0053] In order to facilitate the understanding of this application, the concepts involved in this application are first introduced below:

[0054] RFID tag: RFID tag consists of two parts: RFID antenna and RFID chip. The RFID antenna is responsible for receiving electromagnetic wave energy and reflecting electromagnetic waves, while the RFID chip is responsible for implementing RFID communication protocol and storing digital ID and other information. RFID antenna has a certain impedance, and advanced RFID chips can measure this impedance. In addition, RFID chips with sensing function also have external IO interface for external sensors, and obtain sensing information by measuring the electrical parameters of sensors. Digital ID and other data are transmitted wirelessly between RFID tags and readers. Each RFID tag has a unique digital ID. Attaching RFID tags to items can be used to identify and track each item. RFID tags themselves do not require power supply and are low-cost. Their reading distance can also reach more than 10 meters. This feature makes them widely used in warehouse management, footwear and clothing production and other fields. With the continuous evolution of RFID technology, some special RFID chips with sensing functions have also appeared in recent years, further broadening their scope of application.

[0055] The present application provides a connection component and a connection relationship identification method, which are used to support batch identification of the connection relationship between the optical fiber connector plug and the optical fiber adapter to prevent cross-reading.

[0056] See also Figure 1 , the connection components of the present application can be applied to Figure 1The PON system includes an optical line terminal (OLT), which is used to provide a network-side interface for the optical access network (OAN). The OLT is connected to the network-side equipment on the upper layer, and the lower layer is connected to one or more optical distribution networks (ODN). The ODN includes a passive optical splitter for optical power distribution, a trunk optical cable connected between the passive optical splitter and the OLT, and the trunk optical cable is used to realize the transmission of optical signals between the OLT and the ODN. The ODN also includes a branch optical cable connected between the passive optical splitter and the optical network unit (ONU), and the branch optical cable is used to realize the transmission of optical signals between the ODN and the ONU. When the OLT needs to transmit a downstream optical signal to the ONU, the ODN transmits the downstream optical signal from the OLT to each ONU through the passive splitter. Similarly, when the ONU needs to transmit an upstream optical signal to the OLT, the ODN aggregates the upstream optical signal from the ONU and transmits it to the OLT. ONU provides a user-side interface for OAN and is connected to ODN at the same time. If ONU also provides user port functions, such as ONU provides Ethernet user port or plain old telephone service (POTS) user port, it is called optical network terminal (Optical Network Termination, ONT). This application uniformly refers to ONU or ONT as optical network unit ONU. In order to realize optical signal transmission, the optical cable output from OLT is connected to the optical distribution frame (Optical Distribution Frame, ODF) unit included in ODN, and the ODF unit may include one or more ODFs. Through the distribution of the ODF unit, the output optical cable is connected to the fiber distribution terminal (Fiber Distribution Terminal, FDT) unit, and the FDT unit may include one or more FDTs. The FDT unit is used to perform secondary distribution of optical cables. The management scope of an FDT unit may be a community or a street, and the number of connection components connected to the FDT unit can be selected according to the number of users that the FDT unit needs to manage. The FDT unit is connected to the fiber access terminal (Fiber Access Terminal, FAT) unit through an optical cable, and the FAT unit includes one or more FATs. The FAT unit is connected to the ONU, where the FAT unit is used to connect to the user access point of the home optical cable, and the home section optical cable refers to the section of optical cable from the FAT unit to the user's home.The connection component provided in the present application is applied to a patch fiber, that is, two ends of a patch fiber are respectively connected to two connection components, and the patch fiber can be applied to an ODF unit, an FDT unit or a FAT unit, without specific limitation.

[0057] For example, the patch cord is connected in any of the following scenarios:

[0058] It is connected between two interconnected ODFs included in the ODF unit, between different adapters of the same ODF, between the OLT and the ODF, between two interconnected FDTs included in the FDT unit 105, between different adapters of the same FDT, between two interconnected FATs included in the FAT unit, between the FAT unit and an access terminal box (ATB), or between the FAT unit and the ONU.

[0059] The following is a detailed introduction to several structures of the connection components in this application:

[0060] Structure 1.

[0061] See also Figure 2a The connection assembly in the present application includes an optical fiber adapter 201 and an optical fiber connector plug 202. An RFID antenna 203 is provided at a port on one side of the optical fiber adapter 201. The RFID antenna 203 has an antenna impedance, and the value of the antenna impedance can be used to identify the optical fiber adapter 201. Contacts are provided on the RFID antenna 203. An RFID chip 204 is provided in the optical fiber connector plug 202. A digital ID is stored in the RFID chip 204. The digital ID can be used to identify the optical fiber connector plug 202. Contacts are also provided on the RFID chip. When the optical fiber connector plug 202 is not inserted into the above port of the optical fiber adapter 201, the RFID antenna 203 and the RFID chip 204 cannot form a complete RFID tag, and no information can be read by an RFID reader at this time; when the optical fiber connector plug 202 is inserted into the above port of the optical fiber adapter 201, the contacts of the RFID antenna 203 contact with the contacts of the RFID chip 204 to form a complete RFID tag. At this time, the RFID reader can read the digital ID, and then the RFID reader sends a command carrying the digital ID to the RFID chip 204. After receiving the command, the RFID chip 204 reads the antenna impedance and returns it to the RFID reader.

[0062] Of course, the positions of the RFID 204 chip and the RFID antenna 203 can also be interchanged, that is, the RFID antenna 203 is set in the optical fiber connector plug 202, and the RFID chip 204 is set in the optical fiber adapter 201.

[0063] See also Figure 2b , the following combination Figure 2a The connection component described in the present application introduces a process of the connection relationship identification method:

[0064] 201. A reader reads a first data pair from a first RFID tag and a second data pair from a second RFID tag, wherein the first data pair includes first identification information and a first antenna impedance, and the second data pair includes second identification information and a second antenna impedance;

[0065] See also Figure 2c , multiple fiber optic adapters are set on the optical cross-connect box distribution frame, one end of the optical fiber is connected to the fiber optic connector plug, and connected to the port of the fiber optic adapter of the optical cross-connect box distribution frame, thereby forming multiple RFID tags. In this scenario, the antenna impedance of the RFID antenna on the different fiber optic adapters of the optical cross-connect box distribution frame is different, for example, from top to bottom, they are 101 ohms, 102 ohms, and 103 ohms, so the fiber optic adapter can be identified according to the size of the antenna impedance. In addition, the digital ID stored in the RFID chip of the fiber optic connector plug connected to each optical fiber is also different, for example, from top to bottom, they are 100, 200, and 300, so the fiber optic connector plug can be identified according to the digital ID. After the optical fiber connection is completed, using an RFID reader to read the optical cross-connect box distribution frame can read data pair 1 from RFID tag 1, data pair 1 includes antenna impedance 101 and digital ID 100; read data pair 2 from RFID tag 2, data pair 2 includes antenna impedance 102 and digital ID 200; read data pair 3 from RFID tag 3, data pair 3 includes antenna impedance 103 and digital ID 300.

[0066] 202. The reader determines, according to the first data pair, that the first connection device is connected to the second connection device, and determines, according to the second data pair, that the third connection device is connected to the fourth connection device.

[0067] The reader pre-stores the correspondence between each fiber optic adapter and antenna impedance, and the correspondence between each fiber optic connector plug and digital ID. Therefore, the reader can determine that fiber optic connector plug 1 is connected to fiber optic adapter 1 based on data pair 1; based on data pair 2, it can determine that fiber optic connector plug 2 is connected to fiber optic adapter 2; based on data pair 2, it can determine that fiber optic connector plug 3 is connected to fiber optic adapter 3.

[0068] It is not difficult to see that in the above structure, by splitting the RFID tag into the fiber optic adapter and the fiber optic connector plug, the digital ID and impedance can be read by the RFID reader only when the fiber optic connector plug is inserted into the fiber optic adapter, and the fiber optic connector plug and the fiber optic adapter connected together can be identified based on this. Moreover, the digital ID and the impedance come from the same RFID tag, and the corresponding relationship can be directly determined, so that batch reading of the connection relationship can be realized to prevent cross-reading.

[0069] Structure 2

[0070] See also Figure 3a In this implementation, an RFID chip 402 is provided in the optical fiber connector plug 401, and a digital ID is stored in the RFID chip 402. The digital ID can be used to identify the optical fiber connector plug 401, and two contacts are provided on the RFID chip 402. An RFID antenna 404 and an electronic device 405 are provided at a port on one side of the optical fiber adapter 403, and both are provided with contacts. When the contacts of the electronic device 405 are in contact with the contacts of the RFID chip 402, the RFID chip 402 can read the electrical parameters of the electronic device 405, such as capacitance, resistance or inductance, and the electrical parameters can be used to identify the optical fiber adapter 403. When the optical fiber connector plug 401 is not inserted into the above port of the optical fiber adapter 403, the above RFID antenna 404, RFID chip 402 and electronic device 405 cannot form a complete RFID tag, and no information can be read by the RFID reader at this time; when the optical fiber connector plug 401 is inserted into the above port of the optical fiber adapter, the two contacts of the above RFID chip 402 are respectively in contact with the contacts of the RFID antenna 404 and the electronic device 405 to form a complete RFID tag. At this time, the RFID reader can read the above digital ID, and then the RFID reader sends a command carrying the digital ID to the RFID chip 402. After receiving the command, the RFID chip 402 reads the electrical parameters and returns them to the RFID reader.

[0071] Combine the following Figure 3a The connection component described in the embodiment introduces another process of the connection relationship identification method in this application:

[0072] 301. A reader reads a first data pair from a first RFID tag and a second data pair from a second RFID tag, wherein the first data pair includes first identification information and a first antenna impedance, and the second data pair includes second identification information and a second antenna impedance;

[0073] See also Figure 3b, multiple fiber optic adapters are set on the optical cross-connect box distribution frame, one end of the optical fiber is connected to the fiber optic connector plug, and connected to the port of the fiber optic adapter of the optical cross-connect box distribution frame, thereby forming multiple RFID tags. In this scenario, the electrical parameters of the electronic devices on the different fiber optic adapters of the optical cross-connect box distribution frame are different. For example, from top to bottom, they are 10 ohm resistors, 20 ohm resistors, and 30 ohm resistors. Then the fiber optic adapter can be identified according to the size of the electrical parameters. In addition, the digital ID stored in the RFID chip of the fiber optic connector plug connected to each optical fiber is also different. For example, from top to bottom, they are 100, 200, and 300 respectively. In this way, the fiber optic connector plug can be identified according to the digital ID. After the optical fiber connection is completed, use an RFID reader to read the optical cross-connect box distribution frame. Data pair 1 can be read from RFID tag 1. Data pair 1 includes a resistor of 10 ohms and a digital ID of 100; data pair 2 can be read from RFID tag 2. Data pair 2 includes a resistor of 20 ohms and a digital ID of 200; data pair 3 can be read from RFID tag 3. Data pair 3 includes a resistor of 30 ohms and a digital ID of 300.

[0074] 302. The reader determines, according to the first data pair, that the first connection device is connected to the second connection device, and determines, according to the second data pair, that the third connection device is connected to the fourth connection device.

[0075] The reader pre-stores the correspondence between each fiber optic adapter and electrical parameters, and the correspondence between each fiber optic connector plug and digital ID. Therefore, the reader can determine that fiber optic connector plug 1 is connected to fiber optic adapter 1 based on data pair 1; based on data pair 2, it can determine that fiber optic connector plug 2 is connected to fiber optic adapter 2; based on data pair 2, it can determine that fiber optic connector plug 3 is connected to fiber optic adapter 3.

[0076] It is not difficult to see that in the above structure, the digital ID and electrical parameters can only be read by the RFID reader when the fiber optic connector plug is inserted into the fiber optic adapter, and the fiber optic connector plug and the fiber optic adapter connected together can be identified based on this. Moreover, the digital ID and the electrical parameters come from the same RFID tag, and the corresponding relationship can be directly determined, so that batch reading of connection relationships can be realized to prevent cross-reading.

[0077] Structure 3:

[0078] See also Figure 4aIn this implementation, an RFID chip 502 and an RFID antenna 503 are provided in the optical fiber connector plug 501. A digital ID is stored in the RFID chip 502, and the digital ID can be used to identify the optical fiber connector plug 501. Contacts are provided on both the RFID chip 502 and the RFID antenna 503. An electronic device 505 is provided at a port on one side of the optical fiber adapter 504, and two contacts are provided on the electronic device 505. When the contacts of the electronic device 505 are in contact with the contacts of the RFID chip 502, the RFID chip 502 can read the electrical parameters of the electronic device 505, such as capacitance, resistance or inductance, and the electrical parameters can be used to identify the optical fiber adapter 504. When the optical fiber connector plug 501 is not inserted into the above port of the optical fiber adapter 504, the above RFID antenna 503, RFID chip 502 and electronic device 505 cannot form a complete RFID tag, and no information can be read by the RFID reader at this time; when the optical fiber connector plug 501 is inserted into the above port of the optical fiber adapter 504, the two contacts of the electronic device 505 are in contact with the contacts of the RFID chip 502 and the RFID antenna 503 respectively, thereby forming a complete RFID tag. At this time, the RFID reader can read the above digital ID, and then the RFID reader sends a command carrying the digital ID to the RFID chip 502. After receiving the command, the RFID chip 502 reads the electrical parameters and returns them to the RFID reader.

[0079] Of course, the positions of the RFID chip 502 , RFID antenna 503 and electronic device 505 can also be interchanged, that is, the electronic device 505 is set in the optical fiber connector plug 501 , and the RFID chip 502 and RFID antenna 503 are set in the optical fiber adapter 504 .

[0081] 401. A reader reads a first data pair from a first RFID tag and a second data pair from a second RFID tag, wherein the first data pair includes first identification information and a first electrical parameter, and the second data pair includes second identification information and a second electrical parameter;

[0082] See also Figure 4b, multiple fiber optic adapters are set on the optical cross-connect box distribution frame, one end of the optical fiber is connected to the fiber optic connector plug, and connected to the port of the fiber optic adapter of the optical cross-connect box distribution frame, thereby forming multiple RFID tags. In this scenario, the electrical parameters of the electronic devices on the different fiber optic adapters of the optical cross-connect box distribution frame are different. For example, from top to bottom, they are 10 ohm resistors, 20 ohm resistors, and 30 ohm resistors. Then the fiber optic adapter can be identified according to the size of the electrical parameters. In addition, the digital ID stored in the RFID chip of the fiber optic connector plug connected to each optical fiber is also different. For example, from top to bottom, they are 100, 200, and 300 respectively. In this way, the fiber optic connector plug can be identified according to the digital ID. After the optical fiber connection is completed, use an RFID reader to read the optical cross-connect box distribution frame. Data pair 1 can be read from RFID tag 1. Data pair 1 includes a resistor of 10 ohms and a digital ID of 100; data pair 2 can be read from RFID tag 2. Data pair 2 includes a resistor of 20 ohms and a digital ID of 200; data pair 3 can be read from RFID tag 3. Data pair 3 includes a resistor of 30 ohms and a digital ID of 300.

[0083] 402. The reader determines, according to the first data pair, that the first connection device is connected to the second connection device, and determines, according to the second data pair, that the third connection device is connected to the fourth connection device.

[0084] The reader pre-stores the correspondence between each fiber optic adapter and electrical parameters, and the correspondence between each fiber optic connector plug and digital ID. Therefore, the reader can determine that fiber optic connector plug 1 is connected to fiber optic adapter 1 based on data pair 1; based on data pair 2, it can determine that fiber optic connector plug 2 is connected to fiber optic adapter 2; based on data pair 2, it can determine that fiber optic connector plug 3 is connected to fiber optic adapter 3.

[0085] It is not difficult to see that in the above structure, the digital ID and electrical parameters can only be read by the RFID reader when the fiber optic connector plug is inserted into the fiber optic adapter, and the fiber optic connector plug and the fiber optic adapter connected together can be identified based on this. Moreover, the digital ID and the electrical parameters come from the same RFID tag, and the corresponding relationship can be directly determined, so that batch reading of connection relationships can be realized to prevent cross-reading.

[0086] Structure 4:

[0087] See also Figure 5aIn this implementation, an RFID chip 602 and an RFID antenna 603 are provided in the optical fiber connector plug 601. A digital ID is stored in the RFID chip 602, and the digital ID can be used to identify the optical fiber connector plug 601. The RFID chip 602 and the RFID antenna 603 are fixedly connected together through contacts. In addition, another contact is provided on the RFID chip 602. An electronic device 605 is provided at a port on one side of the optical fiber adapter 604, and a contact is provided on the electronic device 605. When the contact of the electronic device 605 contacts the contact of the RFID chip 602, the RFID chip 602 can read the electrical parameters of the electronic device 605, such as capacitance, resistance or inductance, and the electrical parameters can be used to identify the optical fiber adapter 604. When the fiber optic connector plug 601 is not inserted into the above-mentioned port of the fiber optic adapter 604, the above-mentioned RFID antenna 603 and the RFID chip 602 can also form an RFID tag, and the digital ID can be read by the RFID reader at this time; when the fiber optic connector plug 601 is inserted into the above-mentioned port of the fiber optic adapter 604, the contacts of the electronic device 605 are in contact with the contacts of the RFID chip 602, and the RFID chip 602, the RFID antenna 603 and the electronic device 605 form a complete RFID tag. At this time, the RFID reader sends an instruction carrying the above-mentioned digital ID to the RFID chip 602, and the RFID chip 602 reads the electrical parameters after receiving the instruction and returns them to the RFID reader.

[0088] Of course, the positions of the RFID chip 602 , RFID antenna 603 and electronic device 605 can also be interchanged, that is, the electronic device 605 is set in the fiber optic connector plug 601 , and the RFID chip 602 and RFID antenna 603 are set in the fiber optic adapter 604 .

[0089] Combine the following Figure 5a The connection component described in the embodiment introduces another process of the connection relationship identification method in this application:

[0090] 501. A reader reads a first data pair from a first RFID tag and a second data pair from a second RFID tag, wherein the first data pair includes first identification information and a first electrical parameter, and the second data pair includes second identification information and a second electrical parameter;

[0091] See also Figure 5b, multiple fiber optic adapters are set on the optical cross-connect box distribution frame, one end of the optical fiber is connected to the fiber optic connector plug, and connected to the port of the fiber optic adapter of the optical cross-connect box distribution frame, thereby forming multiple RFID tags. In this scenario, the electrical parameters of the electronic devices on the different fiber optic adapters of the optical cross-connect box distribution frame are different. For example, from top to bottom, they are 10 ohm resistors, 20 ohm resistors, and 30 ohm resistors. Then the fiber optic adapter can be identified according to the size of the electrical parameters. In addition, the digital ID stored in the RFID chip of the fiber optic connector plug connected to each optical fiber is also different. For example, from top to bottom, they are 100, 200, and 300 respectively. In this way, the fiber optic connector plug can be identified according to the digital ID. After the optical fiber connection is completed, use an RFID reader to read the optical cross-connect box distribution frame. Data pair 1 can be read from RFID tag 1. Data pair 1 includes a resistor of 10 ohms and a digital ID of 100; data pair 2 can be read from RFID tag 2. Data pair 2 includes a resistor of 20 ohms and a digital ID of 200; data pair 3 can be read from RFID tag 3. Data pair 3 includes a resistor of 30 ohms and a digital ID of 300.

[0092] 502. The reader determines, according to the first data pair, that the first connection device is connected to the second connection device, and determines, according to the second data pair, that the third connection device is connected to the fourth connection device.

[0093] The reader pre-stores the correspondence between each fiber optic adapter and electrical parameters, and the correspondence between each fiber optic connector plug and digital ID. Therefore, the reader can determine that fiber optic connector plug 1 is connected to fiber optic adapter 1 based on data pair 1; based on data pair 2, it can determine that fiber optic connector plug 2 is connected to fiber optic adapter 2; based on data pair 2, it can determine that fiber optic connector plug 3 is connected to fiber optic adapter 3.

[0094] It is not difficult to see that in the above structure, only when the optical fiber connector plug is inserted into the optical fiber adapter can the digital ID and electrical parameters be read by the RFID reader, and the optical fiber connector plug and the optical fiber adapter connected together can be identified based on this, and the digital ID and electrical parameters come from the same RFID tag, and the corresponding relationship can be directly determined, so batch reading of connection relationships can be achieved to prevent cross-reading. And if only the digital ID can be read, it means that the optical fiber connector plug identified by the digital ID is vacant.

[0095] Of course, in the aforementioned embodiments, the digital IDs stored in the RFID chips of the optical fiber connector plugs at both ends of the same optical fiber can be set to a specific corresponding relationship, for example, the last bit of the two digital IDs is 0 and 1 respectively, and the remaining bits are the same. The above method can facilitate the identification of two optical fiber connector plugs connected to the same optical fiber, and then determine that there is a connection relationship between the optical fiber adapters connected to the two optical fiber connector plugs.

[0096] Of course, the fiber optic connector plug and fiber optic adapter in the connection assembly of the present application may also be replaced with other devices having a connection relationship, such as plugs and sockets existing in various application scenarios, which are not listed one by one here.
