Description

Technical Field

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

[0002] With the development of the Internet, smart homes, and virtual reality devices, the demand for network speed in home scenarios is getting higher and higher. Under this demand, the fiber to the room (FTTR) solution has been proposed.

[0003] The optical communication network used in the existing FTTR solution is mainly composed of a master optical modem and multiple slave optical modems, and the master optical modem and the multiple slave optical modems are connected through a splitter. In actual operation, after receiving the digital optical signal 1 from the optical line terminal (OLT), the main functions of the master optical modem include: (1) converting the digital optical signal 1 into a digital electrical signal 1 through an optical module; (2) performing data format conversion and other operations on the digital electrical signal 1 through devices such as field programmable gate array (FPGA) to obtain a digital electrical signal 2; (3) providing a corresponding data interface for the optical module and mobile hotspot (i.e. WiFi) chip on the slave optical modem side through the gateway control chip, performing communication protocol conversion on the digital electrical signal 2 to obtain a digital electrical signal 3, and distributing the digital electrical signal 3 to the optical module and WiFi chip on the slave optical modem side; (4) converting the digital electrical signal into an analog RF electrical signal, processing and sending the analog RF electrical signal through the WiFi chip, the RF front module and the antenna; wireless RF signal transmission; (5) converting the digital electrical signal 3 into a digital optical signal 2 through the optical module on the slave optical modem side, and sending it to the optical splitter. The optical splitter is used to distribute the digital optical signal 2 to multiple slave optical modems. The main functions of each slave optical modem include: (1) converting digital optical signal 2 into digital electrical signal 4 through an optical module; (2) converting digital electrical signal 4 into a digital electrical signal 5 through a gateway control chip; (3) converting digital electrical signals into analog RF electrical signals and processing and sending analog RF electrical signals through a WiFi chip, a RF front-end module, and an antenna. In this optical communication network, the master optical modem and the slave optical modem need to implement more data processing and signal processing processes, which results in a more complex hardware structure and high power consumption for the master optical modem and the slave optical modem. At the same time, more data processing and signal processing also result in a higher communication delay between the two. In particular, the method of distributing optical signals through a splitter will result in a longer uplink waiting delay for each slave optical modem, further exacerbating the delay problem. Therefore, the optical communication network used by the existing FTTR solution has high power consumption and high latency, resulting in poor applicability and practicality of the FTTR solution.

[0072] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings provided in the embodiments of the present application.

[0073] In the various embodiments of the present application, unless otherwise specified or provided for in any logical conflict, the terms and / or descriptions between the different embodiments are consistent and may be referenced to each other, and the technical features in the different embodiments may be combined to form new embodiments according to their inherent logical relationships.

[0074] In the present application, "at least one" means one or more, and "more than one" means more than two (including two). "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. In the text description of the present application, the character " / " generally indicates that the previous and next associated objects are in an "or" relationship; in the formula of the present application, the character " / " indicates that the previous and next associated objects are in a "division" relationship. "Including at least one of A, B and C" can mean: including A; including B; including C; including A and B; including A and C; including B and C; including A, B and C.

[0075] It is understood that the various numbers involved in the embodiments of the present application are only for the convenience of description and are not used to limit the scope of the embodiments of the present application. The size of the sequence number of the above-mentioned processes does not mean the order of execution, and the execution order of each process should be determined by its function and internal logic.

[0076] The optical communication network used in existing FTTR solutions is usually composed of a master optical modem and multiple slave optical modems, and the master optical modem is connected to each slave optical modem through a splitter. Since the master optical modem and the slave optical modem need to implement more data processing and signal processing processes, the hardware structure of the master optical modem and the slave optical modem is relatively complex and has high power consumption. At the same time, more data processing and signal processing also make the communication delay between the two higher. In particular, the method of distributing optical signals through splitters will cause the uplink waiting delay of each slave optical modem to be longer, further exacerbating the delay problem. Therefore, the existing optical communication network has problems such as high power consumption and high latency, which affects the applicability and practicality of the FTTR solution.

[0077] Therefore, the technical problem to be solved by this application is: how to reduce the power consumption and latency of optical communication networks, thereby improving the applicability and practicality of FTTR solutions.

It should be noted that the naming of the communication device 100 and the M electronic devices is only exemplary. In some possible implementations, the above-mentioned communication device 100 may also be referred to as the main communication device 100, and the above-mentioned electronic device 200 may also be referred to as the slave communication device 200. Alternatively, the above-mentioned communication device 100 may also be referred to as the first optical communication device 100, and the above-mentioned electronic device 200 may also be referred to as the second optical communication 200, and the present application does not impose specific restrictions on this. It should also be noted that in the embodiment of the present application, the transmission process of the signal from the communication device 100 to the electronic device 200 is defined as downlink, and the transmission process of the signal from the electronic device 200 to the communication device 100 is defined as uplink. Correspondingly, the transmission medium through which the signal goes downlink may be referred to as a downlink channel or a downlink, and the transmission medium through which the signal goes uplink may be referred to as an uplink channel or an uplink.

[0080] like Figure 1 As shown, the communication device 100 may include a second optical module 101, a gateway control module 102, a radio frequency conversion module 103, and a radio frequency transceiver module 104. Among them, the second optical module 101 is connected to the gateway control module 102, the gateway control module 102 is connected to the radio frequency conversion module 103, the radio frequency conversion module 103 is connected to the radio frequency transceiver module 104, and the radio frequency transceiver module 104 is also connected to each of the above-mentioned M electronic devices. The electronic device 200 mainly includes a first optical module 201, a first filter amplifier 202 and a first antenna 203. It should be noted that the filter amplifier involved in this application refers to a functional component that can filter and / or amplify radio frequency electrical signals, and this application does not require its implementation form.

[0081] In actual work, the second optical module 101 is used to receive the first digital optical signal. It should be noted that the first digital optical signal may come from other devices or apparatuses connected to the communication device 100. For example, the first digital optical signal may come from the OLT to which the communication device 100 is connected, or the first digital optical signal may come from the network unit (optical network unit, ONU) to which the communication device 100 is connected. After receiving the first digital optical signal, the second optical module 101 may convert the first digital optical signal into a first digital electrical signal, and send the first digital electrical signal to the gateway control module 102. It should be noted here that in the embodiment of the present application, the conversion between signals refers to direct conversion, that is, the conversion directly completed by an independent chip, circuit or module, rather than indirect conversion completed only by multiple chips, circuits or modules. For example, the conversion of the first digital optical signal into the first digital electrical signal mentioned above means that the first digital optical signal can be converted into the first digital electrical signal through the second optical module 101, and it is not necessary to first convert the first digital optical signal into an intermediate signal through a chip, circuit or module other than the second optical module 101, and then convert the intermediate signal into the first digital electrical signal through the second optical module 101. The so-called conversion in the following text is the same, and it will not be repeated to avoid redundancy.

[0082] The gateway control module 102 can be used to convert the first digital electrical signal into a second digital electrical signal, and send the second digital electrical signal to the RF conversion module 103. The communication protocols corresponding to the first digital electrical signal and the second digital electrical signal are different. In other words, the gateway control module 102 is used to perform communication protocol conversion on the first digital electrical signal to obtain the corresponding second digital electrical signal. Exemplarily, assuming that the above-mentioned first digital electrical signal satisfies the PON protocol, and the transmission between the gateway control module 102 and the RF conversion module 103 is based on the WiFi communication protocol, the gateway control module 102 can convert the first digital electrical signal that satisfies the PON protocol into a second digital signal that satisfies the WiFi communication protocol.

[0083] The RF conversion module 103 is used to convert the second digital electrical signal into a first RF electrical signal, and send the first RF electrical signal to the RF transceiver module 104. Optionally, the RF conversion module 103 is used to perform digital-to-analog conversion on the second digital electrical signal to obtain a corresponding first RF electrical signal.

[0084] The RF transceiver module 104 is used to obtain N first RF optical signals according to the first RF electrical signal, and send the N first RF optical signals to N electronic devices among the M electronic devices, respectively. Wherein, N is a positive integer greater than or equal to 1, and the N electronic devices include the electronic device 200. It should be understood that sending the N first RF optical signals to the N electronic devices among the M electronic devices respectively means sending a unique first RF optical signal among the N first RF optical signals to each of the N electronic devices, and each of the N electronic devices receives only one first RF optical signal.

[0085] Furthermore, the first optical module 201 is used to receive one RF optical signal among the N first RF optical signals, convert the first RF optical signal into a twelfth RF electrical signal, and send the twelfth RF electrical signal to the first filter amplifier 202 .

[0086] The first filter amplifier 202 is used to filter and amplify the twelfth radio frequency electrical signal to obtain a thirteenth radio frequency electrical signal, and send the thirteenth radio frequency electrical signal to the first antenna 203. The first antenna 203 can be used to transmit the thirteenth radio frequency electrical signal. It should be understood that in the embodiment of the present application, the antenna is mainly used to send radio frequency electrical signals to a device or apparatus that establishes a wireless communication connection with the electronic device 200 through the antenna, or to receive radio frequency electrical signals from these devices or apparatuses. The device or apparatus here can be a mobile phone, a computer, a wearable device, etc., and the present application does not limit this.

[0087] In the above implementation, on the one hand, for the communication device 100, since the communication between it and the electronic device is transmitted through radio frequency optical signals, its gateway control module 102 only needs to provide a data interface to the radio frequency conversion module 103. The gateway control module 102 can provide more data processing capabilities for the communication device 100, so that the communication device 100 can implement more data processing operations through the gateway control module 102, without relying on devices such as FPGA to perform operations such as data format conversion like the existing main optical modem, so the communication device 100 can save FPGA and other devices. Since there is no need to use FPGA and other devices for data processing, the transmission delay of the signal at the communication device 100 becomes smaller, and the power consumption of the communication device 100 is also reduced. On the other hand, for the corresponding electronic device 200, since it receives radio frequency optical signals, it does not need to perform conversion between digital optical signals and digital electrical signals, nor does it need to perform conversion on the communication protocol. It only needs to convert the received radio frequency optical signals into corresponding radio frequency electrical signals, and then perform filtering and amplification processing to transmit radio frequency electrical signals. Therefore, compared with the existing optical modem, the electronic device 200 provided in the present application has a simpler structure and needs to perform fewer signal processing operations, so the transmission delay of the signal at the electronic device 200 is smaller, and the power consumption of the electronic device 200 is also lower. In addition, since the communication device 200 is directly connected to each electronic device instead of being indirectly connected through a splitter, it supports uplink concurrency of multiple electronic devices, which can avoid the uplink waiting delay of each electronic device 200, thereby further reducing the delay generated by the signal at the electronic device. Therefore, the optical communication network 300 composed of the communication device 100 and M electronic devices has low power consumption and small delay. Therefore, applying the optical communication network 300 provided in the present application to the FTTR solution can improve the applicability and practicality of the FTTR solution.

[0088] For some alternative implementations, see Figure 2 , Figure 2 This is a structural diagram of an electronic device provided by this application. Figure 2 As shown, the electronic device 200 may further include a first duplexer 204, a second filter amplifier 205 and a second antenna 206. The first duplexer 204 is connected to the first optical module 201, the first filter amplifier 202 and the second filter amplifier 205 respectively, and the second filter amplifier 205 is also connected to the second antenna 206.

[0089] In actual work, the first optical module 201 can send the twelfth radio frequency electrical signal obtained by its conversion to the first duplexer 204. The first duplexer 204 can be used to decompose the twelfth radio frequency electrical signal into a fourteenth radio frequency electrical signal and a fifteenth radio frequency electrical signal, send the fourteenth radio frequency electrical signal to the first filter amplifier 202, and send the fifteenth radio frequency electrical signal to the second filter amplifier 205. Among them, the frequency bands corresponding to the fourteenth radio frequency electrical signal and the fifteenth radio frequency electrical signal are different. It should be understood that the duplexer provided in the present application is mainly used to decompose the radio frequency electrical signal according to different frequency bands (i.e., frequency ranges), or to merge radio frequency electrical signals of different frequency bands to form one radio frequency electrical signal. The frequency bands that the duplexer can decompose or merge are determined by its performance indicators, and the present application does not impose specific restrictions on this. Exemplarily, assuming that the frequency bands that the first duplexer 204 can decompose or combine are the 2.4G frequency band and the 5.8G frequency band, the first duplexer 204 can decompose the twelfth RF electrical signal into the fourteenth RF electrical signal located in the 2.4G frequency band and the fifteenth RF electrical signal located in the 5.8G frequency band.

[0090] The second filter amplifier 205 is used to filter and / or amplify the fifteenth radio frequency electrical signal to obtain a sixteenth radio frequency electrical signal, and send the sixteenth radio frequency electrical signal to the second antenna 206. The second antenna 206 is used to send the sixteenth radio frequency electrical signal.

[0091] It should be understood that in this case, the first filter amplifier mentioned above is used to filter and amplify the twelfth radio frequency electrical signal to obtain the thirteenth radio frequency electrical signal, that is, it can be understood that the first filter amplifier 202 is used to filter and / or amplify the fourteenth radio frequency electrical signal obtained by decomposing the twelfth radio frequency signal to obtain the thirteenth radio frequency electrical signal.

[0092] In the above implementation, by taking advantage of the RF optical signal transmission, the electronic device 200 can support a larger downlink transmission bandwidth through the design of the first duplexer 204 and multiple antennas, which is beneficial to reducing the structural complexity and cost of the electronic device 200.

[0093] In an alternative implementation, see Figure 3 , Figure 3 This is another structural diagram of an electronic device provided by the present application. Figure 3 As shown, the electronic device 200 may further include a third filter amplifier 207 and a third antenna 208. The third antenna 208 is connected to the first optical module 201 through the third filter amplifier 207.

[0094] In actual operation, the third antenna 208 is used to receive the seventeenth radio frequency electrical signal, and send the seventeenth radio frequency electrical signal to the third filter amplifier 207. The third filter amplifier 207 is used to filter and / or amplify the seventeenth radio frequency electrical signal to obtain an eighteenth radio frequency electrical signal, and send the eighteenth radio frequency electrical signal to the first optical module 201. The first optical module 201 is also used to obtain a second radio frequency optical signal based on the eighteenth radio frequency electrical signal, and send the second radio frequency optical signal to the communication device 100.

[0095] In an alternative implementation, see Figure 4 , Figure 4 This is another structural diagram of an electronic device provided by the present application. Figure 4 As shown, the electronic device 200 further includes a second duplexer 209, a third filter amplifier 207, a third antenna 208, a fourth filter amplifier 210 and a fourth antenna 211. The second duplexer 209 is respectively connected to the first optical module 201, the third filter amplifier 207 and the fourth filter amplifier 210. The third antenna 208 is connected to the third filter amplifier 207, and the fourth antenna 211 is connected to the fourth filter amplifier 210.

[0096] In actual work, the third antenna 208 is used to receive the seventeenth radio frequency electrical signal and send the seventeenth radio frequency electrical signal to the third filter amplifier. The third filter amplifier 207 is used to filter and / or amplify the seventeenth radio frequency electrical signal to obtain the eighteenth radio frequency electrical signal, and send the eighteenth radio frequency electrical signal to the second duplexer 209. The fourth antenna 211 is used to receive the nineteenth radio frequency electrical signal and transmit the nineteenth radio frequency electrical signal to the fourth filter amplifier 210. Among them, the nineteenth radio frequency electrical signal and the seventeenth radio frequency electrical signal correspond to different frequency bands. The fourth filter amplifier 210 is used to filter and / or amplify the nineteenth radio frequency electrical signal to obtain the twentieth radio frequency electrical signal. The second duplexer 209 is used to combine the twentieth radio frequency electrical signal and the eighteenth radio frequency electrical signal to obtain the twenty-first radio frequency electrical signal, and send the twenty-first radio frequency electrical signal to the first optical module 201. The first optical module 201 is also used to convert the twenty-first radio frequency electrical signal into a second radio frequency optical signal, and send the second radio frequency optical signal obtained by the conversion to the communication device 100.

[0097] In the above implementation, by utilizing the advantages of RF optical signal transmission, the electronic device 200 can support a larger downlink and uplink transmission bandwidth through the design of the first duplexer 204, the second duplexer 209 and multiple antennas, which is more conducive to reducing the structural complexity and cost of the electronic device 200.

[0098] For some possible implementations, see Figure 5 , Figure 5This is a schematic diagram of a communication device provided by this application. Figure 5 As shown, the RF transceiver module 104 may include a filter amplifier module 141 and a transceiver module 142. The filter amplifier module 141 is connected to the RF conversion module 103 and the transceiver module 142 respectively, and the transceiver module 142 is connected to M electronic devices respectively.

[0099] In actual operation, the filtering and amplifying module 141 is used to filter and / or amplify the first RF electrical signal from the RF conversion module 103 to obtain a second RF electrical signal, and send the second RF electrical signal to the transceiver module 142. The transceiver module 142 is used to obtain N1 first RF optical signals according to the second RF electrical signal.

[0100] For some possible implementations, see Figure 6 , Figure 6 This is a schematic diagram of a communication device provided by this application. Figure 6 As shown, the filter amplifier module 141 may include a fifth filter amplifier 1411, and the transceiver module 142 may include a first RF power splitter 1421 and M third optical modules. Wherein, M is a positive integer greater than or equal to 2, and N is equal to M. It can also be understood that in this implementation, the number of third optical modules included in the communication device 100 is the same as the number of electronic devices, and the communication device 100 will send a first RF optical signal to each electronic device.

[0101] In actual work, the fifth filter amplifier 1411 is used to filter and / or amplify the first RF electrical signal to obtain a second RF electrical signal, and send the second RF electrical signal to the first RF power divider 1421. The first RF power divider 1421 is used to obtain M third RF electrical signals according to the second RF electrical signal, and send the M third RF electrical signals to M third optical modules respectively. It should be understood that one third optical module only sends one third RF electrical signal. It should also be noted that in an embodiment of the present application, the RF power divider is mainly used to decompose an input RF electrical signal into multiple RF electrical signals according to a set power ratio and output them, or to merge multiple input RF electrical signals into one RF electrical signal and output it. The above-mentioned first RF power divider 1421 is used for branching RF electrical signals.

[0102] The M third optical modules are used to convert the M third RF electrical signals into M first RF optical signals, and send the M first RF optical signals to M electronic devices respectively. Among them, a third optical module is used to convert a third RF electrical signal into a first RF optical signal, and send the converted first RF optical signal to the electronic device connected thereto. For example, assuming that the target third optical module is connected to the electronic device 200, after receiving the third RF electrical signal, the target third optical module converts it into a first RF optical signal, and sends the first RF optical signal to the electronic device 200. At the same time, other third optical modules do not send the first RF optical signal to the electronic device 200.

[0103] For further information, see Figure 7 , Figure 7 This is another structural diagram of a communication device provided by the present application. Figure 7 As shown, in Figure 6 Based on the structure shown, the filter amplifier module 141 may further include a sixth filter amplifier 1412. The transceiver module 142 may further include a second radio frequency power splitter 1422.

[0104] In actual work, the above-mentioned M third optical modules are also used to receive M second RF optical signals, and convert the M second RF optical signals into M fourth RF electrical signals. It should be understood that the above-mentioned M second RF optical signals come from the above-mentioned M electronic devices respectively. The second RF power divider 1422 is used to merge the M fourth RF electrical signals into a fifth RF electrical signal, and send the fifth RF electrical signal to the sixth filter amplifier 1412. The sixth filter amplifier 1412 is used to filter and / or amplify the fifth RF electrical signal to obtain a sixth RF electrical signal, and send the sixth RF electrical signal to the RF conversion module 103. The RF conversion module 103 is also used to convert the sixth RF electrical signal into a third digital signal, and send the third digital signal to the gateway control module 102. The gateway control module 102 is used to convert the third digital signal into a fourth digital signal, and send the fourth digital signal to the second optical module 101. Among them, the communication protocol corresponding to the third digital electrical signal and the second digital electrical signal is the same, and the communication protocol corresponding to the first digital electrical signal and the fourth digital electrical signal is the same. The second optical module 101 is further configured to convert the fourth digital electrical signal into a second digital optical signal, and send the second digital optical signal.

[0105] In the above implementation, two RF power dividers are used to realize the combining and splitting of RF electrical signals, which can save the number of channels of the RF conversion module 103 and thus reduce the cost of the communication device 100 .

[0106] In an alternative implementation, see Figure 8 , Figure 8This is another structural diagram of a communication device provided by the present application. Figure 8 As shown, the communication device 100 may further include a fifth antenna 105, which is connected to the first RF power divider 1421. In actual operation, the first RF power divider 1421 may split the second RF electrical signal to obtain M third RF electrical signals and a twenty-fifth RF electrical signal, and send the M third RF electrical signals to the M third optical modules respectively, and send the twenty-fifth RF electrical signal to the fifth antenna 105. The fifth antenna 105 may send the twenty-fifth RF electrical signal.

[0107] In the above implementation, by providing the fifth antenna 105 in the communication device 100 , the communication device 100 can also have a radio frequency electrical signal transmission function, which can improve the applicability of the communication device 100 .

[0108] In an alternative implementation, see Fig. 9 , Fig. 9 This is another structural diagram of a communication device provided by the present application. Figure 8 As shown, the communication device 100 may also include a sixth antenna 106, which is connected to the second RF power divider 1422. In actual operation, the sixth antenna 106 can receive a twenty-sixth RF electrical signal, and transmit the twenty-sixth RF electrical signal to the second RF power divider 1422. The second RF power divider 1422 can be used to combine the M fourth RF electrical signals and the twenty-sixth RF electrical signal into a fifth RF electrical signal, and send the fifth RF electrical signal to the sixth filter amplifier 1412.

[0109] In the above implementation, by providing the sixth antenna 106 in the communication device 100 , the communication device 100 can also have a radio frequency electrical signal receiving function, which can also improve the applicability of the communication device 100 .

[0110] For some possible implementations, see Fig.10 , Fig.10 This is another structural diagram of a communication device provided by the present application. Fig.10 As shown, the RF transceiver module 104 may include a filter amplifier module 141 and a transceiver module 142. The RF conversion module 103 may include M RF conversion submodules, the filter amplifier module 141 may include M seventh filter amplifiers, and the transceiver module 142 may include M third optical modules. Among them, the M RF conversion submodules are respectively connected to the M third optical modules through the M seventh filter amplifiers. M is a positive integer greater than or equal to 2. It should be understood that one RF conversion submodule is connected to one third optical module only through one seventh filter amplifier. The above-mentioned M RF conversion submodules are respectively connected to the gateway control module 102.

[0111] It should be noted that Fig.10 In the structure shown, there is a unique channel between each RF conversion submodule and each electronic device, so the communication device 100 can communicate with each of the M electronic devices separately, so in this case, the number of first RF optical signals sent by the communication device 100 does not need to be consistent with the number of electronic devices M. In other words, the communication device 100 can send a first RF optical signal to an electronic device among the M electronic devices, or send a first RF optical signal to each of the M electronic devices. Under this architecture, the communication process between the communication device 100 and each electronic device is similar. In order to avoid redundancy, the electronic device 200 will be used as an example for explanation below.

[0112] It is assumed here that the gateway control module 102 establishes a communication connection with the electronic device 200 through a target RF conversion submodule among the M RF conversion submodules, a target seventh filter amplifier among the M seventh filter amplifiers, and a target third optical module among the M third optical modules. In actual work, the gateway control module 102 can send the second digital electrical signal to the target RF conversion submodule. The target RF conversion submodule can be used to convert the second digital electrical signal into a first RF electrical signal and send it to the target seventh filter amplifier. The target seventh filter amplifier can be used to filter and / or amplify the first RF electrical signal to obtain a second RF electrical signal, and send the second RF electrical signal to the target third optical module. The target third optical module is used to obtain a first RF optical signal based on the second RF electrical signal, and send the first RF optical signal to the electronic device 200.

[0113] In the above implementation, the communication device 100 adopts such an architecture so that each electronic device has an independent channel, which can improve the channel capacity between the communication device 100 and the electronic devices.

[0114] Optional, see Fig.11 , Fig.11 This is another structural diagram of a communication device provided by the present application. Fig.11 As shown, the filtering and amplifying module 141 further includes M eighth filtering amplifiers, and the M radio frequency conversion submodules are further connected to the M third optical modules respectively through the M eighth filtering amplifiers.

[0115] In actual work, the M third optical modules are also used to receive M second RF optical signals, and convert the M second RF optical signals into M third RF electrical signals. The M eighth filter amplifiers are also used to filter and / or amplify the M third RF electrical signals to obtain M fourth RF electrical signals. The M RF conversion submodules are also used to convert the M fourth RF electrical signals into M third digital electrical signals. The gateway control module 102 is also used to obtain a fourth digital electrical signal based on the M third digital electrical signals. Among them, the communication protocol corresponding to the third digital electrical signal and the second digital electrical signal is the same, and the communication protocol corresponding to the first digital electrical signal and the fourth digital electrical signal is the same. The above-mentioned second optical module 101 is also used to convert the fourth digital electrical signal into a second digital optical signal, and send the second digital optical signal.

[0116] Optional, see Fig.12 , Fig.12 This is another structural diagram of a communication device provided by the present application. Fig.12 As shown, the communication device 100 may further include a fifth antenna 105, a ninth filter amplifier 107, and a radio frequency conversion submodule 108. The ninth filter amplifier 107 is connected to the gateway control module 102 via the radio frequency conversion submodule 108. The fifth antenna 105 is connected to the ninth filter amplifier 107.

[0117] In actual work, the gateway control module 102 may send the second digital electrical signal to the RF conversion submodule 108. The RF conversion submodule 108 may convert the second digital electrical signal into a twenty-seventh RF electrical signal and send it to the ninth filter amplifier 107. The ninth filter amplifier 107 is used to filter and / or amplify the twenty-seventh RF electrical signal to obtain a twenty-fifth RF electrical signal. The fifth antenna 105 is used to send the twenty-fifth RF electrical signal.

[0118] In the above implementation, by providing the fifth antenna 105 in the communication device 100 , the communication device 100 can also have a radio frequency electrical signal transmission function, which can improve the applicability of the communication device 100 .

[0119] Optional, see Fig.13 , Fig.13 This is another structural diagram of a communication device provided by the present application. Fig.13 As shown, the communication device 100 may further include a sixth antenna 106, a tenth filter amplifier 109, and a radio frequency conversion submodule 110. The tenth filter amplifier 109 is connected to the gateway control module 102 via the radio frequency conversion submodule 110. The sixth antenna 106 is connected to the tenth filter amplifier 109.

[0120] In actual operation, the sixth antenna 106 is used to receive the twenty-sixth radio frequency electrical signal. The tenth filter amplifier 109 is used to filter and / or amplify the twenty-sixth radio frequency electrical signal to obtain the processed twenty-sixth radio frequency electrical signal. The radio frequency conversion submodule 110 is used to convert the processed twenty-sixth radio frequency electrical signal into a fifth digital electrical signal, and send the fifth digital electrical signal to the gateway control module 102. In this case, the gateway control module 102 is used to obtain the fourth digital electrical signal according to the fifth digital electrical signal and the M third digital electrical signals.

[0121] In the above implementation, by providing the sixth antenna 106 in the communication device 100 , the communication device 100 can also have a radio frequency electrical signal receiving function, which can also improve the applicability of the communication device 100 .

[0122] It should be noted that the first optical module and the third optical module involved in the present application are usually RF optical modules packaged in BOSA on board (i.e., optical transmitting and receiving components on board). Optionally, the first optical module and the third optical module may also be in the form of XGPON digital optical module packaging with BOSA on board, but they should meet the key requirements of RF optical modules, such as the input and output impedance is 50ohm, and the signal-to-noise ratio of the output RF signal end of the optical detector should meet certain requirements. It should be understood that in actual implementation, the first optical module and the third optical module should include an optical interface and at least one electrical interface. The optical interface is characterized by a pigtail or pluggable optical fiber port. The electrical signal accessed by the electrical interface should include a combined or branched DC signal and a RF signal. The RF signal is directly connected to the RF link on the board, and the connection form can be a coaxial connector, pin welding, or surface mount welding. In addition, after the third optical module on the communication device 100 and the first optical module on the electronic device 200 are connected, the frequency response curve it supports should be greater than the operating frequency band of the electronic device 200, and the flatness between multiple frequency bands should meet certain requirements to support single-fiber multi-band simultaneous transmission of frequency division multiplexing.

[0123] For some possible implementations, see Fig.14 , Fig.14 This is another structural diagram of an electronic device provided by the present application. Fig.14 As shown, the electronic device 200 may further include a controller 213, a coupler 212 and a switch component 214. The first filter amplifier 202 is connected to the first antenna 203 through the coupler 212, the third filter amplifier 207 is connected to the third antenna through the switch component 214, the coupler 212 is connected to the switch component 214, and the switch component 214 is connected to the controller 213.

[0124] In actual work, when it is determined that the communication device 100 communicates normally with the electronic device 200, or when it is determined that there is no need to perform a closed-loop check on the electronic device, the controller 213 is used to control the switch component 214 so that the coupler 212 is disconnected from the third filter amplifier 207 and the third antenna 208 is connected to the third filter amplifier 207. In other words, the switch component 214 is controlled so that the radio frequency electrical signal received by the third antenna 208 can reach the third filter amplifier 207 through the switch component 214, while the radio frequency electrical signal output by the first filter amplifier 202 cannot reach the third filter amplifier 207 through the coupler 212 and the switch component 214. Accordingly, when it is determined that a closed-loop check is performed on the electronic device 200, the controller 213 is used to control the switch component 214 so that the coupler 212 is connected to the third filter amplifier 207 and the third antenna 208 is disconnected from the third filter amplifier 207. That is to say, the switch component 214 is controlled so that the RF electrical signal received by the third antenna 208 cannot reach the third filter amplifier 207 through the switch component 214, while the RF electrical signal output by the first filter amplifier 202 can reach the third filter amplifier 207 through the coupler 212 and the switch component 214.

[0125] It should be noted that the controller 213 may be the main controller of the electronic device 200, the switch component 214 may be a controllable switch device of various shapes, and the coupler 212 may be an analog coupler of various forms. The present application does not impose any restrictions on the specific implementation form of the switch component 214 and the coupler 212, as long as it can achieve the above functions.

[0126] It should also be noted that, in actual operation, the controller 213 can determine whether to perform a closed-loop check on the electronic device 200 based on the indication signal received from the communication device 100, and the controller 213 can also determine whether to perform a closed-loop check on the electronic device 200 based on the user control instructions received, and the present application does not impose any restrictions on this.

[0127] In the above implementation, through the action of the coupler 212 and the switch component 214, the electronic device 200 can achieve closed-loop verification by multiplexing its upstream and downstream channels, so that the electronic device 200 does not need to introduce an independent calibration channel to achieve closed-loop verification, which can reduce its structural complexity and cost.
