[0077] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0078] In the description of this invention, the use of terms such as "first," "second," etc., is for the purpose of distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features indicated, or implicitly indicating the order of the technical features indicated.

[0079] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, etc., are based on the orientation or positional relationship shown in the drawings and are only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0080] In the description of this invention, it should be noted that, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0081] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of the present invention, not all embodiments.

[0082] It should be noted that the fiber optic code consists of multiple reflection and transmission markers, which can be distinguished by the different wavelengths of the reflected and transmitted light waves or the different spacing of the markers, thus achieving a unique characteristic of the fiber optic code under light waves. Specifically, the reflection or transmission markers of the fiber optic code can be implemented in various ways, mainly including fiber gratings, reflective films (sheets), transmission films (sheets), and silicon baseline etched gratings. Since the existing reflective films (sheets) and transmission films (sheets) have large wavelength widths, they are not suitable for current application scenarios; silicon baseline etched gratings can be directly etched on the silicon substrate of the beam splitter, but the silicon substrate requires a small size, the spacing between the silicon baseline etched grating and the beam splitter is very small, requiring high precision in light source pulses and acquisition space, and the cost is also very high; fiber gratings, including reflective fiber gratings, transmission fiber gratings, phase fiber gratings, etc., are directly etched on the optical fiber, can be directly connected to optical fiber products, and have a relatively low cost. Therefore, fiber gratings are preferred as the fiber optic code in this embodiment of the invention.

[0083] Reference Figure 1As shown, the optical coupling device 100 provided in this embodiment of the invention includes: a first optical splitter 110, a first optical fiber code 120, an optical distribution unit 130, a first resolution control unit, and multiple wavelength division multiplexers 140. The first optical splitter 110 includes a first input terminal, a first output terminal, and a second output terminal. The first input terminal is used to connect to an optical fiber code monitoring device. The first optical fiber code 120 is disposed on an optical fiber at the first input terminal. The optical distribution unit 130 includes a second input terminal, multiple third output terminals, and a first control input terminal. The second input terminal is connected to the first output terminal. The input terminal of the first resolution control unit is connected to the second output terminal, and the output terminal is electrically connected to the first control input terminal. The first resolution control unit is used to resolve signals to control the port switching of the optical distribution unit 130. Each wavelength division multiplexer 140 includes a third input terminal, a fourth input terminal, and a fourth output terminal. The multiple third input terminals are respectively connected to the multiple third output terminals one-to-one. The multiple fourth input terminals are respectively used to connect to the multiple communication devices 300 one-to-one. Each fourth output terminal is used to connect to an optical cable 500.

[0084] Specifically, refer to Figure 1 The diagram shows the structure of the optical coupling device 100 according to an embodiment of the present invention. The first input terminal of the first beam splitter 110 receives the control light wave signal or identification light wave signal emitted by the fiber optic coding monitoring device 400. The first beam splitter 110 is an unequal-splitting beam splitter, specifically outputting 5% of the split light to the first resolution control unit for resolution processing, thereby controlling the connection of each port of the switching optical distribution unit 130. This allows the remaining 95% of the split light to be output from the third output terminal of the target, enabling the wavelength division multiplexer 140 of the target to couple the communication light wave signal emitted by the communication device 300 with the control light wave signal or identification light wave signal. After coupling, the coupled light wave signal is output, thus realizing the co-transmission of communication information and control information over the same cable. Simultaneously, when the identification light wave signal emitted by the fiber optic coding monitoring device 400 passes through the first fiber optic code 120, the first fiber optic code 120 reflects the identification light wave signal and transmits it back to the fiber optic coding monitoring device 400 for processing, thereby realizing the identification and verification of the optical coupling device 100.

[0085] It should be noted that the optical distribution unit 130 can be an optical switch or a beam splitter. Since the light wave is split into multiple paths, the attenuation will increase. Therefore, beam splitters are suitable for short-distance fiber optic coding monitoring and identification. On the other hand, optical switches can perform one-to-many alternating switching, thereby reducing attenuation. Therefore, they are suitable for long-distance fiber optic coding monitoring and identification.

[0086] In this embodiment, by receiving the control optical wave signal emitted by the fiber optic coding monitoring device 400 and processing it through the first parsing control unit, the port connection between the control switching optical distribution unit 130 and multiple wavelength division multiplexers 140 is controlled. Therefore, the control optical wave signal and the communication optical wave signal can be coupled in the target wavelength division multiplexer 140, thereby achieving synchronous transmission of communication and control information. This facilitates faster and more efficient networking connections between multiple ports in the subsequent access communication switching device 200. Simultaneously, by receiving the identification optical wave signal emitted by the fiber optic coding monitoring device 400 and reflecting it back to the fiber optic coding monitoring device 400 through the first fiber optic code 120, the identification and verification of the optical coupling device 100 are achieved. Therefore, the optical coupling device 100 of this embodiment has the function of synchronously transmitting communication and control information, providing a necessary condition for the subsequent construction of an automatic networking verification system, enabling the rapid and synchronous establishment of dynamic networking links during communication.

[0087] In some embodiments, such as Figure 1 As shown, the first analytical control unit includes: a first filter 151, a first photoelectric converter 152, a first analog-to-digital converter 153, and a first controller 154. The input terminal of the first filter 151 is connected to the second output terminal; the input terminal of the first photoelectric converter 152 is connected to the output terminal of the first filter 151, and the first photoelectric converter 152 is used to convert optical wave signals into electrical signals for output; the input terminal of the first analog-to-digital converter 153 is electrically connected to the output terminal of the first photoelectric converter 152; the input terminal of the first controller 154 is electrically connected to the output terminal of the first analog-to-digital converter 153, and the output terminal is electrically connected to the first control input terminal.

[0088] Specifically, refer to Figure 1When the first beam splitter 110 outputs 5% of the split light to the first resolution control unit, it first passes through the first filter 151 to filter out light waves unrelated to the control light wave signal. The control light wave signal is then transmitted to the first photoelectric converter 152 to be converted into an analog electrical signal. Further, the first analog-to-digital converter 153 converts the analog electrical signal into a digital signal, enabling the control unit to control the connections between the ports of the optical distribution unit 130 upon receiving the digital signal. It is understood that the first controller 154 stores the first fiber optic code 120 information of the optical coupling device 100, and the control light wave signal also contains the first fiber optic code 120 information. Therefore, when the first controller 154 receives the control light wave signal, it can identify the first fiber optic code 120 information and process the corresponding segment of the control light wave signal, thereby achieving control switching of the ports of the optical distribution unit 130. The first photoelectric converter 152 can use a PIN photodiode for photoelectric conversion or an avalanche photodiode (APD) for photoelectric conversion. The core processor of the first controller 154 can be a microcontroller, DSP, or ARM, specifically an STM32 series processor.

[0089] Additionally, refer to Figure 2 The present invention also provides a communication switching device 200, including: a plurality of second optical splitters 210, a plurality of second optical fiber codes 220, an optical switch matrix 230, a plurality of third optical splitters 240, a plurality of third optical fiber codes 250, an optical convergence unit 260, and a second resolution control unit. Each second optical splitter 210 includes a first port, a second port, and a third port. Each first port is used to connect to an optical coupling device 100 as described in any embodiment of the present invention via an optical cable 500. Multiple second fiber codes 220 are respectively disposed one-to-one on the optical fibers at the multiple second ports. The optical switch matrix 230 includes multiple fourth ports, multiple fifth ports, and a second control input terminal. The multiple fourth ports are respectively connected one-to-one with the multiple second ports. Each third optical splitter 240 includes a sixth port, a seventh port, and an eighth port. The multiple sixth ports are respectively connected one-to-one with the multiple fifth ports. Each eighth port is used to connect to the optical cable 500 or the communication device 300. Multiple third fiber codes 250 are respectively disposed one-to-one on the optical fibers at the multiple sixth ports. Multiple input terminals of the optical convergence unit 260 are respectively connected one-to-one with the multiple third ports and the multiple seventh ports. The input terminal of the second resolution control unit is connected to the output terminal of the optical convergence unit 260, and the output terminal is electrically connected to the second control input terminal. The second resolution control unit is used to resolve signals to control the port switching of the optical switch matrix 230.

[0090] Specifically, refer to Figure 2The coupled optical wave signal is transmitted to the communication switching device 200 via optical cable 500. First, it is transmitted to the second beam splitter 210 of the target. The second beam splitter 210 is an unequal-splitting beam splitter, specifically outputting 10% of the split light to the optical convergence unit 260 for convergence, and then further transmitted to the second resolution control unit for resolution processing. This controls the connection between the fourth and fifth ports of the switching optical matrix 230, allowing the remaining 90% of the split light to be transmitted through the connection path between the fourth and fifth ports of the target. That is, while transmitting communication information, the optical switching matrix 230 can be used to achieve synchronous port switching, constructing an automatic switching optical network. Simultaneously, the identification optical wave signal emitted by the fiber optic coding monitoring device 400, upon passing through the second fiber optic code 220 and the third fiber optic code 250, is reflected sequentially by the second and third fiber optic codes and transmitted back to the fiber optic coding monitoring device 400 for processing, thereby achieving identification and verification of the optical switching matrix 230 and its ports.

[0091] It is understood that in the accompanying drawings of this invention, only one communication device 300 is used as an example on the transmitting side. Therefore, for multiple communication devices 300 on the transmitting side, the communication optical wave signals emitted by them can be coupled to the control optical wave signal or identification optical wave signal emitted by the fiber optic coding monitoring device 400 in the optical coupling device 100 of this embodiment of the invention. Specifically, refer to Figure 1 The control or identification optical signals output from the multiple third output terminals of the optical distribution unit 130 are coupled to the communication optical signals output from the multiple fourth input terminals in multiple wavelength division multiplexers 140 according to the target requirements, to obtain multiple coupled optical signals. (Continue to refer to...) Figure 2 After transmission via optical cable 500, multiple coupled optical wave signals are split by multiple second beam splitters 210. 10% of the split light output from each third port is transmitted to optical convergence unit 260 for convergence. This allows the second analysis control unit to uniformly analyze and process multiple control optical wave signals co-carried with multiple communication optical wave signals, thereby controlling the connection between multiple fourth and fifth ports of the switching matrix 230. This enables multiple coupled optical wave signals to be transmitted separately along the target path. Simultaneously, the identification optical wave signal emitted by the fiber optic coding monitoring device 400 is coupled by optical coupling device 100 and transmitted to the target's second fiber optic code 220 and third fiber optic code 250. The first fiber optic code 120 reflects the identification optical wave signal and transmits it back to the fiber optic coding monitoring device 400 for processing, thus achieving identification verification of the optical coupling device 100.

[0092] Understandably, reference Figure 2The optical switch matrix 230 has many-to-many ports. Since there is no need to distinguish between input and output ports, when the fourth port is used as an input, the fifth port is used as an output; and vice versa. Therefore, multiple second optical splitters 210 and multiple third optical splitters 240 can be connected to multiple fourth ports and multiple fifth ports, respectively, and multiple second fiber codes 220 and multiple third fiber codes 250 can be set accordingly. That is, the second optical splitters 210 and the third optical splitters 240 are indistinguishable and can both be used as the required optical splitters at the input of the optical switch matrix 230. Furthermore, regarding the second fiber codes 220 and 250, when the second fiber code 220 is used as the fiber code at the input of the optical switch matrix 230, the third fiber code 250 is used as the fiber code at the output of the optical switch matrix 230; when the second fiber code 220 is used as the fiber code at the output of the optical switch matrix 230, the third fiber code 250 is used as the fiber code at the input of the optical switch matrix 230.

[0093] Furthermore, the optical convergence unit 260 can be a beam splitter or an optical switch; for cost considerations, a beam splitter is preferred. The second fiber code 220 and the third fiber code 250 both consist of two parts: the first part has the same grating code, used as an identifier for the communication switching device 200; the second part has different grating codes, used to distinguish the various ports of the optical switch matrix 230. Specifically, with... Figure 2 For example, the specific codes of the four second fiber codes 220 can be: 12001201, 12001202, 12001203, 12001204, and the specific codes of the four second fiber codes 220 can be: 12001205, 12001206, 12001207, 12001208.

[0094] In this embodiment, the received coupled optical wave signal is split into two paths by using the second beam splitter 210. One path is output to the optical convergence unit 260 and then transmitted to the second analysis and control unit for processing, thereby controlling the switching of the optical switch matrix 230. This allows the other output coupled optical wave signal to be transmitted through the connection between the fourth and fifth ports of the target, and finally output. Simultaneously, by receiving the identification optical wave signal emitted by the fiber optic coding monitoring device 400, which is then reflected back to the fiber optic coding monitoring device 400 through the second fiber optic coding 220 and the third fiber optic coding 250 of the target, the identification and verification of the communication switching device 200 is achieved. Therefore, for the communication switching device 200 of this embodiment, port connections can be established simultaneously during the transmission of communication information. By using multiple communication switching devices 200 to form a topology network, an automatic switching optical network can be constructed. Furthermore, the fiber optic coding set at each port can be identified by the fiber optic coding monitoring device 400 to determine whether the communication information is being transmitted at the target port.

[0095] In some embodiments, such as Figure 2 As shown, the second analytical control unit includes: a second filter 271, a second photoelectric converter 272, a second analog-to-digital converter 273, and a second controller 274. The input terminal of the second filter 271 is connected to the output terminal of the light converging unit 260; the input terminal of the second photoelectric converter 272 is connected to the output terminal of the second filter 271, and the second photoelectric converter 272 is used to convert the light wave signal into an electrical signal for output; the input terminal of the second analog-to-digital converter 273 is electrically connected to the output terminal of the second photoelectric converter 272; the input terminal of the second controller 274 is electrically connected to the output terminal of the second analog-to-digital converter 273, and the output terminal is electrically connected to a second control input terminal.

[0096] Specifically, refer to Figure 2When the second beam splitter 210 transmits 10% of the split light to the second analysis and control unit after processing by the optical convergence unit 260, it first passes through the second filter 271 to filter out light waves unrelated to the control light wave signal. The control light wave signal is then transmitted to the second photoelectric converter 272 to be converted into an analog electrical signal. Further, the second analog-to-digital converter 273 converts the analog electrical signal into a digital signal, enabling the control unit to control the connections between the ports of the optical switch matrix 230 upon receiving the digital signal. It is understood that the second controller 274 stores the second fiber optic code 220 information and the third fiber optic code 250 information of the optical coupling device 100. The control light wave signal also contains the second fiber optic code 220 information or the third fiber optic code 250 information. Therefore, when the second controller 274 receives the control light wave signal, it can identify the second fiber optic code 220 information or the third fiber optic code 250 information and analyze the corresponding segment of the control light wave signal, thereby realizing the control switching of each port of the optical switch matrix 230. The second photoelectric converter 272 can use a PIN photodiode or an avalanche photodiode (APD) for photoelectric conversion. The core processor of the second controller 274 can be a microcontroller, DSP, or ARM, specifically an STM32 series processor.

[0097] In addition, refer to Figure 3 This invention also provides an automatic network verification system, comprising: an optical coupling device 100 as described in any embodiment of this invention, a communication device 300, an optical fiber encoding monitoring device 400, and a communication switching device 200 as described in any embodiment of this invention. The communication device 300 is connected to a fourth input terminal; the optical fiber encoding monitoring device 400 is connected to a first input terminal, and the optical fiber encoding monitoring device 400 establishes external communication with the communication device 300; the first port of the communication switching device 200 is connected to the fourth output terminal via an optical cable 500.

[0098] Specifically, such as Figure 3 As shown, the communication device 300 and the fiber optic coding monitoring device 400 are respectively connected to the optical coupling device 100 to couple the communication optical wave signal with the control optical wave signal or the identification optical wave signal. The optical coupling device 100 is further connected to the communication switching device 200 through the optical cable 500, so that the communication device 300 can communicate in the automatic fiber optic network. It should be noted that an external communication is established between the communication device 300 and the fiber optic coding monitoring device 400 for synchronously sending optical wave signals to facilitate coupling in the optical coupling device 100.

[0099] It is understood that by coupling the communication optical wave signal emitted by the communication device 300 and the control optical wave signal emitted by the fiber optic coding monitoring device 400 in the optical coupling device 100 of this embodiment of the invention to obtain a coupled optical wave signal, which is then transmitted to the communication switching device 200 to complete automatic addressing communication, thereby realizing the function of automatic networking. Simultaneously, the identification optical wave signal emitted by the fiber optic coding monitoring device 400 is transmitted to the first fiber optic code 120, coupled, and then transmitted to the second fiber optic code 220 and the third fiber optic code 250, and sequentially reflected back for processing, thereby realizing the identification and verification of the optical coupling device 100 and the communication switching device 200 of this embodiment of the invention, thus achieving the automatic verification function. Therefore, the automatic networking verification system of this embodiment of the invention solves the drawback of long-term reliance on manual operation to connect fiber optic devices, enabling the entire fiber optic network to be established quickly and without errors.

[0100] In some embodiments, such as Figure 4 As shown, multiple communication switching devices 200 are provided. The multiple communication switching devices 200 are connected to form a communication switching device 200 topology network via optical fiber 500. The communication switching device 200 of the master node of the communication switching device 200 topology network is connected to the optical coupling device 100. The communication switching devices 200 of multiple terminal nodes of the communication switching device 200 topology network are respectively used to connect to other communication devices 300.

[0101] Specifically, in combination Figure 3 and Figure 4 Understandable Figure 3 The example only shows one communication switching device 200, that is, the eighth port can be connected to the communication device 300 on the receiving side, thus forming a complete communication exchange between the communication devices 300. It should be noted that a communication filter needs to be connected between the eighth port and the communication device 300 to filter out other optical wave signals that are not communication optical wave signals. The eighth port can also be connected to an optical cable 500 to further connect other communication switching devices 200, thus forming a more complex topology network of communication switching devices 200. Similarly, the control switching principle for each communication switching device 200 is the same as described above, and will not be repeated here.

[0102] In some embodiments, such as Figure 4 As shown, multiple communication devices 300 are provided, and each communication device 300 is connected to one of the multiple fourth input terminals of the optical coupling device 100. Each communication device 300 establishes external communication with the optical fiber encoding monitoring device 400.

[0103] Specifically, in combination Figure 3 and Figure 4 Understandable Figure 3The example only shows one communication device 300 on the transmitting side. For multiple communication devices 300, they can be connected one-to-one with the multiple fourth input terminals of the optical coupling device 100, so that the communication information of multiple communication devices 300 can be transmitted in the automatic optical fiber network.

[0104] In some embodiments, such as Figure 5 As shown, the fiber optic coding monitoring device 400 includes: multiple pulse light sources 410, an optical coupling module 420, a circulator 430, a third photoelectric converter 440, a third analog-to-digital converter 450, and a third controller 460. The multiple pulse light sources 410 are used to output pulsed light waves of different wavelengths; multiple input terminals of the optical coupling module 420 are connected to the output terminals of the multiple pulse light sources 410; the circulator 430 includes a first port, a second port, and a third port, with the first port connected to the output terminal of the optical coupling module 420 and the second port connected to the first input terminal; the input terminal of the third photoelectric converter 440 is connected to the third port of the circulator 430, and the third photoelectric converter 440 is used to convert optical wave signals into electrical signals for output; the input terminal of the third analog-to-digital converter 450 is electrically connected to the output terminal of the third photoelectric converter 440; the third controller 460 is electrically connected to the multiple pulse light sources 410, the output terminal of the third analog-to-digital converter 450, and the communication device 300.

[0105] Specifically, refer to Figure 5Multiple pulse light sources 410 can emit pulse light waves of different wavelengths, and at least one pulse light source 410 has two operating modes: emitting control pulse light waves and identifying pulse light waves. Specifically, in some embodiments, the control pulse light wave is continuous pulse information, while the identifying pulse light wave is a single pulse light wave followed by a longer waiting time, thereby achieving the distinction between the two types of pulse light waves. Therefore, according to the target requirements, the third controller 460 controls the multiple pulse light sources 410 to emit pulse light waves of different wavelengths. After coupling processing by the optical coupling module 420, a control light wave signal or an identifying light wave signal is obtained. That is, the control light wave signal has several control information used to control the ports of the optical coupling device 100 and the ports of the communication switching device 200; the identifying light wave signal has several identification information used to identify the first fiber code 120, the second fiber code 220, and the third fiber code 250. The control or identification light wave signal can be output to the outside via circulator 430. Simultaneously, the third photoelectric converter 440 receives the reflected identification light wave signal via circulator 430, converts it into an analog electrical signal, and further converts the analog electrical signal into a digital signal via third analog-to-digital converter 450. After processing by the third controller 460, the identification of the optical coupling device 100 and the communication switching device 200 can be finally achieved. It is understood that the third photoelectric converter 440 can use a PIN photodiode or an avalanche photodiode (APD) for photoelectric conversion. The core processor of the third controller 460 can be a microcontroller, DSP, or ARM, specifically an STM32 series processor.
