Optical network communication method and communication device The application is a divisional application, the application number of the original application is 202510179612.X, the original application date is 2025, 02 and 18 days, the whole content of the original application is incorporated by reference, and the original application requires that the priority of China patent application with the application number of 202510039018.0 and the application name of 'an optical network communication method and communication device' is filed on the 09 th year 2025, 01 and the whole content of the original application is incorporated by reference. Technical Field The embodiment of the application relates to the field of optical communication, in particular to an optical network communication method and a communication device. Background Fiber-to-room (fiber to the room, FTTR) refers to a technique of providing fiber medium access to a room downstream of an optical network device (e.g., an optical network terminal (optical network terminal, ONT)) with fiber instead of a network cable. The fiber optic network in this FTTR scenario includes a master device and one or more slave devices (also referred to as sub-devices). The master device and the slave device can establish a management channel, so that the master device can send a message related to management or control to the slave device through the management channel, and the management or control of partial functions of the slave device by the master device is realized. In the current standard, the slave device can determine to use a certain authentication encryption mode based on preconfigured information in an initialization phase for providing security authentication for a terminal device accessing the network. Such an implementation may result in multiple slaves managed by the same master using different authenticated encryption modes. That is, the authentication encryption mode of the entire network may be inconsistent, which may affect not only the security of a part of devices (e.g., terminal devices accessed to the network through slave devices), but also the processing complexity of terminal devices accessed to the network through slave devices, which may affect the power consumption and service stability of the terminal devices. Disclosure of Invention The application provides an optical network communication method and a communication device, which are used for improving the safety of equipment. In a first aspect, the present application provides an optical network communication method applied to an optical fiber network, where the optical fiber network includes a master device and at least one slave device. The optical network communication method provided in the present aspect may be executed by a host device in the optical fiber network, or may be executed by a part of functional modules or chips in the host device. Taking the execution of the master device as an example, the master device receives at least one first message, wherein the at least one first message is respectively from at least one slave device, the first message comprises first indication information, the first indication information is used for indicating at least one authentication encryption mode supported by the corresponding slave device, then the master device sends at least one second message, the at least one second message corresponds to the at least one slave device one by one, and the second message comprises second indication information, and the second indication information is used for indicating the corresponding slave device to use the first authentication encryption mode. In the conventional technology, the slave device does not report the authentication encryption capability, and only enables the pre-configured authentication encryption mode, which may cause multiple slave devices managed by the same master device to use different authentication encryption modes. May affect part of the security of the device (e.g. by a terminal device accessing the network from the device). In the invention, after receiving the authentication encryption capability of at least one slave device, the master device can indicate a determined authentication encryption mode (for example, a first authentication encryption mode) to the at least one slave device, so that the slave devices managed by the master device uniformly use the authentication encryption mode, which is beneficial to improving the security of the network. In one possible implementation, the at least one authentication encryption mode includes at least one of the following modes: A 64-bit wired equivalent privacy WEP-64 mode, or a 128-bit wired equivalent privacy WEP-128 mode, or a user-oriented Wi-Fi protected access WPA-Personal mode, or a WPA2-Personal mode, or a WPA-WPA2-Personal mode, or a WPA3-SAE, or a WPA2-WPA3-PSK-SAE, or an Enterprise-oriented Wi-Fi protected access WPA-Enterprise, or a WPA2-Enterprise, or a WP
