Description

Technical Field

[0001] Embodiments of the present application relate to the field of communications, and in particular, to an optical component, a gateway component, a communication device, a communication method, and a communication network. Background Art

[0002] Passive optical network (PON) technology is a fiber access technology with advantages such as low networking cost and strong anti-interference ability, and has gradually become the mainstream communication technology of modern communications. PON structure includes: optical line terminal (OLT) located at the central control station, optical network unit (ONU) or optical network terminal (ONT) located at the user end. Among them, ONT includes PON gateway equipment (also known as network connector, protocol converter), which is an important part of PON.

[0003] At present, Wi-Fi technology has become the most widely used wireless transmission technology, and more and more users access the Internet through Wi-Fi technology. Therefore, PON gateway devices usually integrate PON technology and Wi-Fi technology at the same time, wherein the integrated PON technology provides access services for PON gateway devices, and the integrated Wi-Fi technology provides wireless hotspot access services for users. However, due to the limitation of the terminal position of broadband access media (such as home optical fiber), operators can only install gateway devices that provide Wi-Fi signals near the terminal position of the access medium. For example, for ordinary users, the operator's home optical fiber can only be deployed to the user's home information box, so the PON gateway device can only be deployed in a sealed information box or in a corner outside the information box. If the PON gateway device is deployed in the information box, the Wi-Fi signal will be weak, and the user needs to install a router to expand the coverage of the Wi-Fi signal, and the networking cost is high; if the PON gateway device is deployed in a corner outside the information box, it will be difficult for Wi-Fi to cover the entire range of the user's home, and the coverage of the Wi-Fi signal is not ideal, and the best Wi-Fi signal coverage cannot be provided to the user. Summary of the invention

[0004] The present application provides an optical component, a gateway component, a communication device, a communication method and a communication network. By deploying the communication device, the deployment cost of the communication network can be reduced and the signal coverage of the communication network can be improved.

[0005] In the first aspect, an optical component is provided. The optical component is used to connect a gateway component via a cable. The optical component includes: an optical module, a processing circuit, and a user interface; the first end of the optical module is used to connect to a transmission optical fiber, the second end of the optical module is connected to the processing circuit, and the optical module is used to transmit an optical signal with the transmission optical fiber; the first end of the user interface is used to connect to the gateway component via a cable, and the second end of the user interface is connected to the processing circuit, which is used to transmit an electrical signal with the gateway component; the optical module is used to convert a first optical signal received from the transmission optical fiber into a first electrical signal and send it to the processing circuit, or to convert a fourth electrical signal received from the processing circuit into a second optical signal and send it to the transmission optical fiber; the processing circuit is used to obtain first data from the first electrical signal received from the optical module, and send a second electrical signal carrying the first data to the cable, or to obtain second data from a third electrical signal received from the cable, and send a fourth electrical signal carrying the second data to the optical module.

[0006] In this solution, the optical component is connected to the transmission optical fiber through the optical module, and the cable is connected to the gateway component through the user interface; the processing circuit can obtain data from the electrical signal and send it by processing the electrical signal received from the optical module or cable. Specifically, the optical component can convert the received optical signal into an electrical signal and obtain data from it, or directly obtain data from the received electrical signal; and then send the electrical signal carrying the obtained data to the transmission optical fiber or the gateway component to achieve communication. It is not difficult to understand that the length and number of the cables connecting the user interface and the gateway component can be selected according to actual conditions. For example, in the network deployment scenario of a home, the operator usually deploys the end of the transmission optical fiber in the information box, and enables the user's home to achieve Wi-Fi signal coverage and network access through a gateway device with Wi-Fi function connected to the transmission optical fiber. However, the information box space is small and is usually deployed at the door of the user's home. Due to the space and location of the information box, the Wi-Fi signal coverage of the user's home is often not ideal. By deploying the smaller optical components in this solution in the information box, it can be connected to the transmission optical fiber to achieve home network access for the user; through cables, the optical components can be connected to the gateway components with Wi-Fi functions in the user's home (such as the living room or study), and the communication device formed can serve as a gateway device, thereby effectively improving the Wi-Fi signal coverage of the user's home. Therefore, this solution can reduce the size of the gateway device and effectively improve the signal coverage of the communication network.

[0008] In this solution, the power supply circuit connected to the optical module, the processing circuit and the user interface can receive the voltage transmitted by the cable through the user interface to power the optical module, the processing circuit and the user interface. Among them, the user interface of the optical component is connected to the gateway component through a cable, and the communication device composed can serve as a gateway device. In this way, the voltage provided by the gateway component can be transmitted to the user interface of the optical component through the cable to power the optical component. For example, due to the small internal space of the information box, it is impossible to power the communication equipment (such as optical components, gateway devices). Therefore, it is difficult for the gateway device to obtain power, and the deployment scenarios are limited. However, the optical component in this solution can be deployed in a non-powered scenario, and the optical component is powered by the gateway component, thereby improving the compatibility of the gateway device.

[0009] In one possible implementation, the optical component also includes: a power supply circuit, which connects the optical module, the processing circuit and the user interface; the power supply circuit is also used to connect to an external power adapter, to receive the voltage output by the external power adapter, and to power the optical module, the processing circuit and the user interface through the voltage.

[0010] In this solution, the power circuit is connected to an external power adapter, and the voltage output by the external power adapter can power the optical module, the processing circuit, and the user interface. Then, through the connected external power adapter, the optical component can provide voltage for itself to ensure its normal operation.

[0011] In a possible implementation, the optical component also includes: a power circuit, which is connected to a user interface; the power circuit is also used to connect to an external power adapter, to receive a voltage output by the external power adapter, and to output the voltage to the cable through the user interface.

[0012] In this solution, the power circuit is connected to an external power adapter, and outputs the voltage output by the external power adapter to the cable through the user interface. Since the user interface of the optical component is connected to the gateway component through the cable, the optical component can supply power to the gateway component through the voltage output by the user interface to the cable.

[0013] In a possible implementation, the cable includes: a twisted pair cable, a coaxial cable, or a telephone line.

[0014] In this solution, the cable includes a twisted pair, a coaxial cable or a telephone line. In this way, the optical component can be connected to the gateway component through a cable, and the communication device formed can serve as a gateway device. In this way, the gateway device can be deployed in the existing communication network architecture to communicate with remote communication devices (such as management platforms) and near-end communication devices (such as terminal devices). In addition, the gateway device can manage the communication of the two components (optical components and gateway components) included in the gateway device through the gateway component.

[0016] In this solution, the gateway component is connected to the optical component through a cable connected to the network interface, and is connected to other devices through a user interface; the processing circuit can obtain data and send it by processing the electrical signal received from the network interface or the signal (optical signal or electrical signal) of the user interface. Specifically, the gateway component can convert the received optical signal (such as the second signal) into an electrical signal, and then obtain data from it, or directly obtain data from the received electrical signal, and then send the electrical signal carrying the acquired data to the user interface or the optical component, so as to achieve communication. It is not difficult to understand that the user interface and other devices can be connected by a cable or by a transmission optical fiber; the user interface is not limited to connecting only one device. In a possible implementation, the network interface of the gateway component is connected to the optical component through a cable, and the communication device composed can be used as a gateway device; the user interface of the gateway component is connected to multiple slave gateway devices through a transmission optical fiber, wherein the slave gateway device has a Wi-Fi function. In this way, the coverage of the Wi-Fi signal can be effectively expanded. Then, this solution makes the deployment of the gateway component (such as the connection medium and the connection method) more convenient, facilitates the deployment of the gateway device in the communication network, and effectively improves the signal coverage of the communication network.

[0017] In one possible implementation, the gateway component also includes: a power circuit, which is connected to a user interface; the power circuit is also used to connect to an external power adapter, to receive a voltage output by the external power adapter, and to output the voltage to a cable through a network interface.

[0018] In this solution, the power circuit is connected to an external power adapter, and outputs the voltage output by the external power adapter to the cable through the network interface. Since the network interface of the gateway component is connected to the gateway component through the cable, the gateway device can supply power to the optical component through the voltage output to the cable through the network interface.

[0019] In one possible implementation, the gateway component also includes: a power supply circuit, which is connected to the network interface, the processing circuit and the user interface; the power supply circuit is also used to connect to an external power adapter, to receive the voltage output by the external power adapter, and to power the network interface, the processing circuit and the user interface through the voltage.

[0020] In this solution, the power circuit is connected to an external power adapter, and the voltage output by the external power adapter can power the network interface, the processing circuit, and the user interface. Then, through the connected external power adapter, the gateway component can provide voltage for itself to ensure its normal operation.

[0021] In one possible implementation, the gateway component also includes: a power supply circuit, which is connected to the network interface, the processing circuit and the user interface; the power supply circuit is used to receive the voltage transmitted by the cable through the network interface, and to power the network interface, the processing circuit and the user interface through the voltage.

[0022] In this solution, the power circuit receives the voltage transmitted by the cable through the network interface and supplies power to the network interface, the processing circuit and the user interface. Then, the voltage output by the optical component to the cable through the user interface can be received by the power circuit through the network interface of the gateway component, and the optical component can supply power to the gateway component.

Then, this solution can reduce the structural complexity of the gateway device and reduce costs. In addition, the connection between the optical component and the gateway component in the communication device is not limited, making the deployment scenario of the communication device richer.

[0052] The technical solution in this application will be described below in conjunction with the accompanying drawings.

[0053] The present application will present various aspects, embodiments or features around a system that may include multiple devices, components, modules, etc. It should be understood and appreciated that each system may include additional devices, components, modules, etc., and / or may not include all devices, components, modules, etc. discussed in conjunction with the accompanying drawings. In addition, a combination of these schemes may also be used. It should be noted that in the embodiments of the present application, words such as "exemplary" or "for example" are used to represent examples, illustrations or explanations. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or design schemes. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific manner.

[0054] The technical terms in the embodiments of the present application are described as follows:

[0055] Downlink optical signal:

[0056] In an optical communication system, a downlink optical signal is data sent by a central control station (eg, optical line terminal OLT, management platform) to a communication device on the user side (eg, optical network unit ONU, optical network terminal ONT, etc. on the user side).

[0057] Uplink optical signal:

[0058] In an optical communication system, an uplink optical signal is data sent by a user-side communication device (eg, an optical network unit ONU, an optical network terminal ON, etc.) to a central control station (eg, an optical line terminal OLT, a management platform).

[0059] The technical solutions in the embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0060] Fiber optic communication system has become the mainstream communication system at present. In the fiber optic communication system, the access mode of access network (access network, AN) is fiber access (fiber to the x, FTTx), which is also called optical access network (optical access network, OAN). The fiber optic access modes of fiber optic access network include fiber to the home (fiber to the home, FTTH), fiber to the curb (fiber to the curb, FTTC), fiber to the office (fiber to the office, FTTO), fiber to the building (fiber to the building, FTTB), etc.

[0061] Common fiber access networks include passive optical networks (PON), see Figure 1 As shown, the PON 10 includes an optical line terminal OLT (refer to Figure 1 101), and an optical network terminal ONT or an optical network unit ONU arranged on the user side, wherein the ONT and the ONU are arranged at different positions on the user side and implement similar functions. Therefore, in Figure 1 In the PON 10 shown, the user side is described by taking ONU 103 as an example, wherein: Figure 1 Three ONUs are shown, namely ONU 103 - a , ONU 103 - b , and ONU 103 - c .

[0062] The PON 10 also includes an optical distribution network (ODN) connecting the OLT 101 and the ONU 103 (see Figure 1 102 in ). Figure 1As shown, in ODN 102, two-stage optical splitters are included, wherein the first-stage optical splitter includes optical splitter 1021, and optical splitter 1021 includes an input end, an output end a, an output end b, and an output end c; the second-stage optical splitter includes optical splitter 1022, and optical splitter 1022 includes an input end, an output end a, an output end b, and an output end c. The input end of optical splitter 1021 is connected to OLT 101 through an optical fiber, the output end b of optical splitter 1021 is connected to the input end of optical splitter 1022 through an optical fiber, the output end a of optical splitter 1022 is connected to ONU 103-a through an optical fiber, the output end b of optical splitter 1022 is connected to ONU 103-b through an optical fiber, and the output end c of optical splitter 1022 is connected to ONU 103-c through an optical fiber.

[0063] Exemplarily, the output end a of the optical splitter 1021 can be connected to a second-level optical splitter, or the output end a of the optical splitter 1021 can also be connected to an ONU; the output end c of the optical splitter 1021 can be connected to a second-level optical splitter, or the output end c of the optical splitter 1021 can also be connected to an ONU. Exemplarily, the optical splitter 1021 and the optical splitter 1022 can also include more or fewer output ends. Exemplarily, the ODN 102 can include only a first-level optical splitter, or the ODN 102 can include three or more optical splitters. The function of the ODN 102 is to transmit the downstream optical signal of the OLT 101 to any ONU 103, and to transmit the upstream optical signal of any ONU 103 to the OLT 101. The embodiments of the present application do not limit the number of optical splitters included in the ODN 102, nor do they limit the number of output ports of each optical splitter.

[0064] When PON 10 is working, OLT 101 transmits a downstream optical signal to ODN 102, wherein the input end of the optical splitter 1021 in ODN 102 receives the downstream optical signal, the optical splitter 1021 transmits the downstream optical signal from the output end b of the optical splitter 1021 to the input end of the optical splitter 1022, the optical splitter 1022 transmits the downstream optical signal from the output end a of the optical splitter 1022 to ONU 103-a, the optical splitter 1022 transmits the downstream optical signal from the output end b of the optical splitter 1022 to ONU 103-b, and the optical splitter 1022 transmits the downstream optical signal from the output end c of the optical splitter 1022 to ONU 103-c.

[0065] Exemplarily, taking ONU 103 - a as an example, ONU 103 - a receives a downstream optical signal and processes the received downstream optical signal to obtain data therein.

[0066] In other embodiments, ONU 103-a may also generate an upstream optical signal that needs to be sent to OLT 101. When ONU 103-a generates the upstream optical signal, ONU 103-a transmits the upstream optical signal to OLT 101 through the output end a of splitter 1022, the input end of splitter 1022, the output end b of splitter 1021, and the input end of splitter 1021.

[0067] For example, in Figure 1 In the PON 10 shown, OLT 101, ODN 102 and ONU 103 are connected by optical fibers, and both upstream optical signals and downstream optical signals can be transmitted in these optical fibers. For example, these optical fibers can be single-core bidirectional optical fibers. In addition, the wavelength of the upstream optical signal transmitted in the PON can be different from the wavelength of the downstream optical signal transmitted in the PON (of course, they can also be the same). For example, Figure 1 The wavelength of the downstream optical signal transmitted by the OLT 101 to the ONU 103 - a is λ1, and the wavelength of the upstream optical signal transmitted by the ONU 103 - a to the OLT 101 is λ2, and λ1 is not equal to λ2.

[0068] For different fiber access methods, the deployment method of ONU (such as access location) is also different. For example, in FTTC, ONU is deployed in the central computer room of the community, in FTTB, ONU is deployed in the junction box in the corridor, and in FTTH, ONU is deployed in the user's home. It is not difficult to understand that other networks may be deployed between ONU and users, such as Ethernet. Since ONT and ONU implement similar functions, they are usually regarded as components of ONU and can also be directly deployed at the user end. Specifically, PON usually also includes an optical network terminal ONT deployed at the user end, also known as an "optical modem".

[0069] For example, refer to Figure 2 As shown, a schematic diagram of a communication network is provided. Figure 2As shown, the communication network includes: a remote communication device, a gateway device and a near-end communication device, wherein the gateway device 20 includes: a network interface 201, a processing circuit 202 and a user interface 203; and also includes a processor 204 and a memory 205. Optionally, the processor 204 includes a PON management module. Specifically, one end of the network interface 201 is used to connect to the remote communication device through an optical fiber, and the other end is connected to one end of the processing circuit 202, and the other end of the processing circuit 202 is connected to one end of the user interface 203; the other end of the user interface 203 is used to connect to the near-end communication device through a cable or optical fiber. Optionally, the processor 204 is respectively connected to the network interface 201, the processing circuit 202 and the user interface 203, and is also connected to the memory 205. It is not difficult to understand that the remote communication device includes the above-mentioned OLT, and also includes a management platform, etc., and the near-end communication device includes terminal devices such as mobile phones and tablets. Among them, the ONT (for example) in the communication network can be controlled through the management platform. Figure 2 Gateway device in the system) to realize control and management.

[0070] Specifically, in the downlink direction: the optical signal sent by the remote communication device is transmitted along the optical fiber to the network interface 201 of the gateway device; the network interface 201 converts the received optical signal into an electrical signal and sends it to the processing circuit 202; the processing circuit 202 processes the received electrical signal, obtains data, and transmits the electrical signal carrying the data to the user interface 203; the user interface 203 transmits the received electrical signal to the near-end communication device. In the uplink direction: the signal sent by the near-end communication device is transmitted along the optical fiber or cable to the user interface 203 of the gateway device; the user interface 203 sends the received signal to the processing circuit 202; the processing circuit 202 processes the received electrical signal, obtains data, and transmits the electrical signal carrying the data to the network interface 201; the network interface 201 converts the received electrical signal into an optical signal and sends it to the remote communication device.

[0071] The signal transmitted from the near-end communication device to the user interface 203 may be an electrical signal or an optical signal. However, the network interface of the above-mentioned gateway device needs to be connected to the remote communication device via optical fiber, so the signal transmitted from the network interface to the remote communication device is an optical signal.

[0072] It is not difficult to understand that the above-mentioned gateway device can also be a communication device in the ONT that can realize the function of the gateway device. In a possible implementation, the above-mentioned gateway device can also be used as an ONT. Figure 2 The communication network shown is taken as an example, and this should not be used to limit the types of devices included in the communication network, the architecture of the communication network, etc.

[0073] Currently, Wi-Fi technology has been widely used and has become the main way for users to access the Internet. Therefore, ONTs (such as Figure 2 The gateway device in the middle often also has Wi-Fi function. Operators often deploy the end of the fiber optic cable to the information box of the user's home. The information box is usually located at the entrance of the user's home (for example, in the shoe cabinet at the door of the user's home) and the space is small. In this way, in the FTTH fiber access network, since ONT is used at the user end and the network side interface of ONT usually needs to be connected to other devices through optical fiber, ONT (for example Figure 2 The gateway device in the Wi-Fi network or other ONT with Wi-Fi function can only be deployed in the sealed information box or in the corner outside the information box, so that the network interface of the ONT can be connected to the home optical fiber to achieve network access for the user's home. However, the above solution will result in an unsatisfactory coverage of the Wi-Fi signal, making it difficult to achieve full-house coverage.

[0074] Based on the above problems, for example, refer to Figure 3 As shown in FIG, a deployment scenario diagram of ONT in FTTH optical fiber access network is provided. Figure 3 As shown in (1), the ONT is deployed in the information box, the network interface of the ONT is connected to the optical fiber, and the user interface is connected to the router through a cable. Since the information box is closed and the space is small, the Wi-Fi signal is weak, so it is necessary to deploy a router outside the information box to expand the coverage of the Wi-Fi signal. However, this solution requires the deployment of an additional router, so the deployment cost of this solution is relatively high. Figure 3 As shown in (2), due to the small space inside the information box, it is difficult for the ONT to get power, so the ONT with Wi-Fi function is deployed in the corner outside the information box, where the network interface of the ONT is connected to the optical fiber, and the user interface is connected to the external power adapter through a cable. This solution will result in an unsatisfactory Wi-Fi signal coverage range, making it difficult to achieve full house coverage.

[0075] To solve the above problems, networking is usually performed by using an ONT without Wi-Fi function and a Wi-Fi router, wherein the two are connected by a network cable. Specifically, the ONT without Wi-Fi function can be deployed in a corner outside the information box, and then the Wi-Fi router can be deployed in the TV cabinet in the living room, the desk in the study, etc. according to the actual situation of the user's home network cable laying, so that the coverage of the Wi-Fi signal is better.

[0076] However, due to the large size of ONTs without Wi-Fi functions, they can only be installed outside the information box, making it difficult for the ONT to get power. Such deployment will also make the line deployment messy and unsightly. In addition, ONTs without Wi-Fi and Wi-Fi routers are two independent communication devices, both of which include corresponding packaging, complete machines, power adapters, and accessories, etc., which will greatly increase the deployment cost of the communication network. At the same time, this solution requires installation and maintenance engineers to install and maintain the two communication devices, and the installation and maintenance are relatively complex. In addition, ONTs and Wi-Fi routers usually need to be managed separately using two management platforms, which makes it difficult to achieve synchronous management.

[0077] Based on the above, for example, refer to Figure 4 As shown, an embodiment of the present application provides a schematic diagram of an optical component. The optical component is used to connect a gateway component via a cable. Figure 4 As shown, the optical component 30 includes: an optical module 301, a processing circuit 302 and a user interface 303. Among them, one end of the optical module 301 is used to connect to the optical fiber, and the other end of the optical module 301 is connected to the processing circuit 302, and the optical module 301 is used to transmit optical signals with the optical fiber; one end of the user interface 303 is used to connect to the gateway component through a cable, and the other end of the user interface 303 is connected to the processing circuit 302, and is used to transmit electrical signals with the gateway component.

[0078] Specifically, in the downlink direction: the optical fiber transmits the optical signal to the optical module 301, the optical module 301 receives the optical signal from the optical fiber, converts the optical signal into an electrical signal and sends it to the processing circuit 302; the processing circuit 302 obtains data from the electrical signal received from the optical module 301, and sends the electrical signal carrying the data to the user interface 303; the user interface 303 sends the received electrical signal to the gateway component via the cable. In the uplink direction: the cable transmits the electrical signal sent by the gateway component to the user interface 303, the user interface 303 sends the received electrical signal to the processing circuit 302; the processing circuit 302 obtains data from the electrical signal, and sends the electrical signal carrying the data to the optical module 301; the optical module 301 receives the electrical signal, converts the received electrical signal into an optical signal, and the optical signal is transmitted via the optical fiber.

[0079] It is not difficult to understand that for the sake of convenience, only Figure 4 The architecture shown is taken as an example, and should not be used to limit the number and type of components connected to the optical component, the structure of the optical component, etc. Optionally, the above-mentioned cable (such as the cable connecting the user interface and the gateway component) includes: twisted pair, coaxial cable or telephone line, and its length and number can be selected according to actual conditions.

[0080] Then, the optical component in this solution can convert the received optical signal into an electrical signal and obtain data from it, or directly obtain data from the received electrical signal; then send the electrical signal carrying the obtained data to the optical fiber or gateway component, so as to achieve communication. In the network deployment scenario of the home, the operator usually deploys the end of the optical fiber in the information box, and enables the user's home to achieve Wi-Fi coverage and network access through the gateway device with Wi-Fi connected to the optical fiber. However, the information box space is small and is usually deployed at the door of the user's home. Due to the space and location of the information box, the Wi-Fi signal coverage of the user's home is often not ideal. Then, by deploying the smaller optical component in this solution in the information box, it can be connected to the optical fiber and realize the user's home network access; through the cable, the optical component can be connected to the gateway component with Wi-Fi in the internal location of the user's home (such as the living room, study), forming a gateway device, which can effectively improve the Wi-Fi signal coverage of the user's home.

[0081] In a possible implementation, the optical component 30 further includes: a power supply circuit 304 .

[0082] Optionally, the power circuit 304 connects the optical module 301, the processing circuit 302 and the user interface 303; the power circuit 304 is used to receive the voltage transmitted by the cable through the user interface 303, and to power the optical module 301, the processing circuit 302 and the user interface 303 through the voltage. Then, in this solution, the power circuit can receive the voltage transmitted by the cable through the user interface, and power the optical module, the processing circuit and the user interface. In a possible implementation, the optical component is connected to the remote gateway component through a cable, and the communication device composed can be used as a gateway device. Specifically, the voltage provided by the gateway component can be transmitted to the optical component through the cable, and the optical component can receive the voltage transmitted by the cable through the power circuit, and power the optical module, the processing circuit and the user interface, so as to realize the gateway component to power the optical component. In this way, the solution can solve the problem of power supply of the optical component. For example, in the FTTH optical access network, the internal space of the information box is small, and it is impossible to deploy an external power adapter to power the optical component. Then, the solution can improve the compatibility of the optical component and make the deployment scenario of the optical component richer.

[0083] Optionally, the power supply circuit 304 is connected to the optical module 301, the processing circuit 302 and the user interface 303; the power supply circuit 304 is also used to connect to an external power adapter ( Figure 4 ), for receiving the voltage output by the external power adapter, and using the voltage to power the optical module 301, the processing circuit 302 and the user interface 303. Then, through the connected external power adapter, the optical component can provide voltage for itself to ensure its normal operation.

[0084] In some other examples, the power circuit 304 is optionally connected to the user interface 303; the power circuit 304 is also used to connect to an external power adapter ( Figure 4 303), is used to receive the voltage output by the external power adapter and output the voltage to the cable through the user interface 303. In this solution, the power circuit can be connected to the external power adapter and output the voltage output by the external power adapter to the cable through the user interface. Since the user interface of the optical component is connected to the gateway component through the cable. Therefore, through the voltage output by the user interface to the cable, the optical component can supply power to the gateway component.

[0085] For example, refer to Figure 5 As shown, an embodiment of the present application provides a schematic diagram of a gateway component. The gateway component is used to connect optical components through cables. Figure 5 As shown, the gateway component 40 includes: a network interface 401, a processing circuit 402 and a user interface 403. Among them, one end of the network interface 401 is used to connect the optical component through a cable, and the other end of the network interface 401 is connected to the processing circuit 402, which is used to transmit electrical signals with the optical component; one end of the user interface 430 is connected to the processing circuit 402, and the other end of the user interface 403 is used to connect other devices, which is used to transmit signals with other devices. It is not difficult to understand that since the user interface 403 of the gateway component 40 can transmit signals with other connected devices through cables or optical fibers, the signals transmitted by the user interface 403 of the gateway component 40 and other devices are optical signals or electrical signals.

[0086] Specifically, in the downlink direction: the electrical signal sent by the optical component is transmitted to the network interface 401 through the cable, and the network interface 401 sends the received electrical signal to the processing circuit 402; the processing circuit 402 obtains data from the electrical signal received from the network interface 401, and sends the signal carrying the data to the user interface 403; the signal received by the user interface 403 will be transmitted along the cable or optical fiber. In the uplink direction: the cable or optical fiber transmits the signal to the user interface 403, the user interface 403 sends the received signal to the processing circuit 402, the processing circuit 402 obtains data from the signal received from the user interface 403, and sends the electrical signal carrying the data to the network interface 401; the network interface 401 transmits the received electrical signal to the optical component through the cable.

[0087] It is not difficult to understand that for the sake of convenience, only Figure 5 The architecture shown is taken as an example, and should not be used to limit the number and type of components connected to the optical component, the structure of the optical component, etc. Optionally, the above-mentioned cable (such as the cable connecting the user interface and the gateway component) includes: twisted pair, coaxial cable or telephone line, and its length and number can be selected according to actual conditions.

[0088] In this solution, the gateway component can convert the received optical signal into an electrical signal and then obtain data from it, or directly obtain data from the received electrical signal, and then send the electrical signal carrying the obtained data to the user interface or optical component, thereby achieving communication. It is not difficult to understand that the user interface of the gateway component can be connected to other devices through cables or optical fibers; and it is not limited to connecting only one device. Then, this solution can make the deployment of gateway components (such as connection media and connection methods) more convenient, facilitate the deployment of gateway components in communication networks, and effectively improve the signal coverage of communication networks.

[0089] In a possible implementation, the gateway component 40 further includes: a power circuit 404 .

[0090] Optionally, the power circuit 404 is connected to the network interface 401; the power circuit 404 is also used to connect to an external power adapter ( Figure 5 401), which is used to receive the voltage output by the external power adapter and output the voltage to the cable through the network interface 401. In this solution, the power circuit can be connected to the external power adapter and output the voltage output by the external power adapter to the cable through the network interface. Since the network interface of the gateway component is connected to the gateway component through a cable. Therefore, the gateway device can supply power to the optical component through the voltage output to the cable through the network interface.

[0091] Optionally, the power circuit 404 is connected to the network interface 401, the processing circuit 402 and the user interface 403; the power circuit 404 is also used to connect to an external power adapter ( Figure 5 401, the processing circuit 402 and the user interface 403. In this solution, the power circuit can be connected to the external power adapter, and the voltage output by the external power adapter can be used to power the network interface, the processing circuit and the user interface. Then, through the connected external power adapter, the gateway component can provide voltage for itself to ensure its normal operation.

[0092] In other examples, optionally, the power circuit 404 is connected to the network interface 401, the processing circuit 402, and the user interface 403; the power circuit 404 is used to receive the voltage transmitted by the cable through the network interface 401, and to supply power to the network interface 401, the processing circuit 402, and the user interface 403 through the voltage. In this solution, the power circuit receives the voltage transmitted by the cable through the network interface, and supplies power to the network interface, the processing circuit, and the user interface. Since the network interface of the gateway component is connected to the optical component through a cable, the optical component can output voltage to the cable through the user interface, so the optical component can supply power to the gateway component.

[0093] It should be noted that, in a possible implementation, the above-mentioned gateway component 40 also includes a processor 405, and the processor 405 is connected to the network interface 401, the processing circuit 402, the user interface 403, the power circuit 404 and the memory 406. Among them, the processor 405 is mainly used to realize PON management functions by controlling each connected module and cooperating with the optical component, such as: authentication type, authentication mode, P2P function, rogue ONU detection, controlling the upper and lower limits of the optical power of the optical component, and turning off and on the light emission of the optical component.

[0094] Optionally, the above-mentioned gateway component 40 also includes a memory 406, which is connected to the processor 405. The memory 406 can be used to store configuration information. When the gateway component is powered on, the processor 405 can perform initial configuration on the gateway component by reading the configuration information in the memory 406.

[0095] Based on the above optical components and gateway components, for example, refer to Figure 6 As shown, an embodiment of the present application provides a schematic diagram of a communication device.

It is not difficult to understand that for the sake of convenience, only the optical module 301 of the optical component 30 is connected to the network interface 401 of the gateway component 40 through a cable or an optical fiber. Figure 6 The illustrated architecture is taken as an example, and should not be used to limit the number, type, etc. of components included in the communication device.

[0096] Specifically, in the downlink direction: the optical signal output by the remote communication device is transmitted along the optical fiber to the optical module 301 of the optical component 30, the optical module 301 converts the received optical signal into an electrical signal, and sends it to the processing circuit 302; the processing circuit 302 obtains data from the received electrical signal, and sends the electrical signal carrying the data to the user interface 303; the user interface 303 transmits the received electrical signal to the network interface 401 of the gateway component 40 via a cable, and the network interface 401 sends the received electrical signal to the processing circuit 402; the processing circuit 402 obtains data from the received electrical signal, and sends the signal carrying the data to the user interface 403; the user interface 403 sends the received signal to the near-end communication device via a cable or optical fiber.

[0097] In this solution, the communication device composed of the optical component and the gateway component provided by the embodiment of the present application can be deployed as a gateway device in the communication network. In this way, by deploying the communication device, the structural complexity of the gateway device can be reduced, the deployment cost of the communication network can be reduced, and the signal coverage of the communication network can be improved. In addition, the connection between the optical component and the gateway component in the communication device is not limited, making the deployment scenario of the communication device provided by the embodiment of the present application richer. In addition, the communication device can be used as an independent device, which is easy to install and maintain.

[0112] Optional, see Figure 6 As shown, the processor 405 included in the gateway component 40 is used to control the network interface 401, the processing circuit 402, the user interface 403, the power circuit 404 and the memory 406 to communicate. Specifically, the gateway component 40 receives the request message sent by the optical component 30, and controls the network interface 401, the processing circuit 402, the user interface 403, the power circuit 404 and the memory 406 through the processor 405 to execute the above steps 801-804.

Then, the communication device, as an independent device, can realize data transmission with the remote OLT.

[0114] based on Figure 6 The architecture of the communication device shown in the figure, as an independent device, can realize data transmission with a remote management platform. Fig. 9 As shown, the embodiment of the present application also provides a schematic diagram of a communication method. Figure 4-Figure 6 , the communication method provided by the embodiment of the present application is described in detail. It should be noted that the remote communication device is a management platform, an optical component 30 and a gateway component 40 as an example for description. The communication method includes steps 901 to 906, which are described in detail as follows.

[0115] 901. The gateway component sends a registration authentication message to the management platform through the optical component.

[0116] Combination Fig. 9 As shown, the management platform sends a registration authentication message to the gateway component through the optical component, and the registration authentication message includes the network interconnection protocol address of the management platform. Specifically, the network interface 401 of the gateway component 40 sends the registration authentication message to the user interface 303 of the optical component 30 through a cable, and the optical module 301 of the optical component 30 transmits the received authentication message to the management platform along the optical fiber.

[0117] In a possible implementation, the registration authentication message is used by the communication device to initiate a registration authentication request to the management platform. For example, the registration authentication message includes: a request message (expressed as TR-069Inform) under the customer premise equipment (CPE) wide area network management protocol (technical report-069, TR-069), and authentication information such as the media access control layer hardware address and serial number of the gateway component.

[0123] For example, after the management platform completes the registration and authentication of the communication device, it can send information to the gateway component through the optical component to achieve management of the communication device. For example, the management platform sends parameter configuration or query related to the line of the communication network (for example, first configuration information including one or more configuration parameters) to the gateway component through the optical component, controls the communication device to filter the received first configuration information through the gateway component according to the parameters included in the first configuration information, and other operations.

[0128] Combination Fig. 9 As shown, the optical component sends a configuration validation result in response to the second configuration information to the gateway component. Specifically, the user interface 303 of the optical component 30 sends a configuration validation result in response to the second configuration information to the network interface 401 of the gateway component 40 through a cable.

[0129] 906. The gateway component sends the configuration effectiveness result to the management platform through the optical component.

[0130] Combination Fig. 9 As shown, the gateway component sends the configuration validation result in response to the second configuration information to the management platform through the optical component. Specifically, the network interface 401 of the gateway component 40 sends the configuration validation result in response to the second configuration information to the user interface 303 of the optical component 30 through a cable, and the optical module 301 of the optical component 30 transmits the received configuration validation result to the management platform along the optical fiber.

[0131] Optional, see Figure 6 As shown, the memory 406 included in the gateway component 40 is used to store the above-mentioned configuration information, such as the first configuration information, etc. Specifically, the gateway component 40 receives the first configuration information sent by the management platform forwarded by the optical component 30, and stores the first configuration information in the memory 406; the gateway component 40 reads the first configuration information in the memory 406, obtains the configuration parameters included in the second configuration information, generates the second configuration information, and the network interface 401 of the gateway component 40 sends the second configuration information to the user interface 303 of the optical component 30 through the cable.

[0132] Optional, see Figure 6 As shown, the processor 405 included in the gateway component 40 is used to control the network interface 401, the processing circuit 402, the user interface 403, the power circuit 404 and the memory 406 to communicate. Specifically, the gateway component 40 receives the request message sent by the optical component 30, and controls the network interface 401, the processing circuit 402, the user interface 403, the power circuit 404 and the memory 406 through the processor 405 to execute the above steps 901 to 906.
