[0046] The exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art.

[0047] With the continuous development of informatization, people have higher and higher requirements for the coverage, data bandwidth, and convenient maintenance of communication systems. Network access devices, such as wireless AP (Access Point), PON (Passive Optical Network), ONU (Optical Network Unit), etc., play an important role in network coverage. Due to the special location of these devices, their power supply issues have received more and more attention.

[0048] Over the past decade, the power supply forms of these access devices have been constantly evolving, from the most primitive local power supply, to remote power supply using network cable PoE (Power Over Ethernet), and now to the optical-electrical hybrid cable remote centralized power supply launched by various equipment manufacturers. However, these power supply methods cannot get rid of the use of "copper" metal medium to transmit electrical energy. In the existing technology, network access devices are centrally powered by optical-electrical hybrid cables. Communication optical fibers and power supply wires are bundled together to form a hybrid cable, which is separated at the remote end. Communication optical fibers are used for data transmission, and power supply wires are used to power network access devices. This type of power supply transmits electrical energy through metal media, which is complicated to deploy and requires a large amount of metal resources.

[0049] Based on this, an embodiment of the present application provides a network access device. The solution of the embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0050] See also Figure 1 A structural schematic diagram of a network access device is shown, which includes: a first power module, a first service module, a first optical module, a first optical fiber connection device, a photoelectric conversion module and a controller, the first power module is respectively connected to the first service module, the first optical module and the controller, the first optical module is respectively connected to the first service module and the first optical fiber connection device, the first optical fiber connection device is connected in series with the photoelectric conversion module and the controller in sequence, and the photoelectric conversion module is used to receive the laser signal transmitted by the first optical fiber connection device and convert the laser signal into electrical energy.

[0051] The embodiment of the present application is connected to the optoelectronic conversion module through a first optical fiber connection device, and can transmit laser energy. The optoelectronic conversion module is then used to convert light energy into electrical energy to power the first power module through a controller, so that the first service module can work normally. Compared with the traditional metal wire energy transmission method, it has higher energy transmission efficiency and flexibility; the network access device does not need to lay a large number of cables or wires, so it can save the manufacturing cost of the network access device, reduce the maintenance cost of the network access device, save metal resources, and reduce the risk of failures caused by line aging, damage and other problems, thereby saving the maintenance cost of the network access device.

[0052] In some embodiments of the present application, see Figure 2 As shown, the network access device may further include an energy storage module, and the controller is connected to the energy storage module. After the photoelectric conversion module converts light energy into electrical energy, the energy storage module may be safely charged and discharged through the controller.

[0053] Furthermore, when the controller detects that the optoelectronic conversion module is unstable, the energy storage module can be started to provide stable and continuous power supply to the first power supply module. The first power supply module ultimately supplies power to the first optical module and the first service module of the network access device, so that the network access device itself can operate normally.

[0054] The energy storage module provides backup power when the photoelectric conversion module is unstable, ensuring the continuity and reliability of the network access device, improving the overall operating efficiency of the network access device itself, and effectively managing and distributing electrical energy, reducing energy waste, and improving energy utilization efficiency; in addition, a stable power supply can reduce electrical shocks to the network access device, thereby extending the service life of the network access device.

[0055] See also Figure 3 As shown, based on the above embodiments, in some modified implementations, the first optical module may include a communication chip, the first optical fiber connection device may include a first optical fiber connector and a plurality of second optical fiber connectors connected in series in sequence, one of the plurality of second optical fiber connectors may include a first spectroscopic lens, the second optical fiber connectors containing the first spectroscopic lens are respectively connected to the communication chip and one end of the series line of the remaining second optical fiber connectors, and the other end of the series line of the remaining second optical fiber connectors is connected to the first optical fiber connector and the optoelectronic conversion module, wherein the first optical module may be pluggable.

[0056] Furthermore, a plurality of second optical fiber connectors may be serially connected in sequence via optical fibers.

[0057] In an embodiment of the present application, the received laser is power split by the first splitter lens to obtain a first optical power and a second optical power, and then the first optical power is transmitted to the communication chip so that the communication chip can perform normal communication functions, and the second optical power is led out through the optical fiber to the series line of the remaining second optical fiber connector to transmit the second optical power to the optoelectronic conversion module via the first optical fiber connector. The optoelectronic conversion module converts optical energy into electrical energy based on the second optical power and transmits it to the controller. The controller is used to provide stable and continuous power supply to the first power supply module. The controller also safely charges and discharges the energy storage module.

[0058] The first spectroscopic lens can quickly perform spectroscopic processing as needed and provide instant power support, so that the network access device can better adapt to different working conditions and environmental changes, greatly improving the adaptability of the network device; in addition, the first spectroscopic lens can also flexibly distribute lasers, greatly improving the flexibility of network configuration, thereby improving the scalability of the network access device.

[0059] See also Figure 4 As shown, based on the above embodiments, in some modified implementations, the first optical module may include a communication chip, the first optical fiber connection device may include a first optical fiber connector and a second optical fiber connector, the first optical fiber connector is arranged in the first optical module and connected to the communication chip, and the second optical fiber connector is connected to the optoelectronic conversion module, wherein the first optical module may be pluggable.

[0060] The first optical fiber connector in the network access device is used to provide laser energy for data communication to the communication chip, and the second optical fiber connector is used to provide laser energy to the optoelectronic conversion module. The optoelectronic conversion module converts optical energy into electrical energy based on the second optical power and transmits it to the controller. The controller is used to provide stable and continuous power supply to the first power supply module. The controller also safely charges and discharges the energy storage module, enabling the network access device to fully utilize the received laser energy and avoid wasting laser energy.

[0061] Furthermore, since the first optical module is pluggable, when the first optical module needs to be replaced or upgraded, there is no need to make large-scale hardware changes to the entire network access device, which greatly improves the flexibility of the network access device, makes maintenance and upgrades simpler and faster, and greatly reduces maintenance costs, and reduces network interruption time caused by network access device failures; in addition, since the first optical module is an independent component, its failure will not affect the operation of other modules, which significantly improves the stability and reliability of the network access device; in addition, after the first optical module is unplugged from the network access device, because the second optical fiber connector still exists, the laser energy can continue to be transmitted through the second optical fiber connector, thereby continuing to power the network access device, thereby avoiding affecting the normal use of other modules, greatly improving the utilization efficiency and adaptability of the network access device.

[0062] See also Figure 5 As shown, based on the above embodiments, in some modified implementations, the first optical module includes a communication chip, the first optical fiber connection device includes a first optical fiber connector, the first optical fiber connector includes a first splitter lens, and the first optical fiber connector is arranged in the first optical module and is respectively connected to the first optical module and the optoelectronic conversion module, wherein the first optical module may be non-pluggable.

[0063] The first spectroscopic lens can quickly perform spectroscopic processing as needed and provide instant power support, so that the network access device can better adapt to different working conditions and environmental changes, greatly improving the adaptability of the network device; in addition, the first spectroscopic lens can also flexibly distribute lasers, greatly improving the flexibility of network configuration, thereby improving the scalability of the network access device.

[0064] Furthermore, since the first optical module is non-pluggable, the loss of laser energy during the transmission process can be reduced, thereby ensuring the integrity and efficiency of data transmission.

[0065] On the basis of the above embodiments, in some modified implementations, the photoelectric conversion module may include a laser beam expander and a photovoltaic cell, the laser beam expander is connected to the photovoltaic cell, the first optical fiber connection device is connected to the laser beam expander, and the photovoltaic cell is connected to the controller. The laser beam expander is used to receive the laser signal transmitted by the first optical fiber connection device, shape the laser signal, amplify the diameter of the laser beam, and make the laser signal irradiate the photovoltaic cell evenly and over a large area. After the photovoltaic cell is irradiated by the laser signal, the photoelectric effect of the semiconductor is used to convert the light energy of the laser signal into electrical energy, and the electrical energy is transmitted to the controller.

[0066] Based on the above embodiment, in some modified implementations, the photoelectric conversion module may further include a sealing mask, which is sealed outside the laser beam expander and photovoltaic cell included in the photoelectric conversion module to avoid dust. The sealing mask may be made of polyetherimide.

[0067] Since the material of the sealing cover is resistant to high temperatures, dimensionally stable, chemically resistant, flame retardant, high-strength, and highly rigid, the photoelectric conversion module can effectively prevent the entry of dust, thereby avoiding dust from affecting the performance of photoelectric conversion and improving the power supply performance of network access equipment.

[0068] The network access device of the embodiment of the present application includes: a first power module, a first service module, a first optical module, a first optical fiber connection device, an optoelectronic conversion module and a controller, the first power module is respectively connected to the first service module, the first optical module and the controller, the first optical module is respectively connected to the first service module and the first optical fiber connection device, and the first optical fiber connection device is sequentially connected in series with the optoelectronic conversion module and the controller. The network access device of the present application can use laser transmission energy to power itself, and its deployment is simple and convenient, making the network coverage more flexible and lightweight, and also saving a lot of metal resources.

[0071] The network routing device of the network communication system transmits the laser energy to the network access device through the second optical module via the second optical fiber connection device, the optical fiber, and the first optical fiber connection device, so that the network access device can simultaneously perform data communication and power supply according to the laser energy. Since the laser has strong directivity and concentrated energy, the network routing device of the present application can use a smaller transmission power to achieve long-distance power transmission. Compared with traditional wired communication methods, such as metal communication, laser power transmission is not restricted by the geographical environment, and can stably transmit data under complex terrain and harsh climatic conditions. The laser energy is not easily intercepted or interfered, and has high security; moreover, when the optical fiber transmits laser energy, its loss is much lower than that of metal transmission, which greatly improves the utilization efficiency of laser energy, thereby improving the communication efficiency of the network communication system; in addition, when the optical fiber transmits laser energy, since no metal conductor is used as the transmission medium, it has a strong anti-electromagnetic interference ability, so that the optical fiber can maintain stable communication quality in a complex electromagnetic environment and reduce signal attenuation and distortion; furthermore, the optical fiber does not need to lay a large number of wired cables to transmit laser energy, so it is more flexible and convenient to deploy, especially in emergency communications, temporary network construction and other occasions, the optical fiber can quickly establish a communication link and provide timely communication services.
