Description

Communication device, communication system, and communication method Technical Field The present application relates to the field of communications technologies, and in particular, to a communications device, a communications system, and a communications method. Background In a passive optical network (passive optical network, PON), operation administration and maintenance (operation administration AND MAINTENANCE, OAM) information may be transmitted between a master device and a slave device through PON protocols, such as an Ethernet Passive Optical Network (EPON) and a Gigabit passive optical network (Gigabit-Capable passive optical network, GPON). However, in the scenario of optical wireless communication, switching, control, and signal regeneration are implemented by a master device, and a slave device (i.e., an optical radio frequency communication device) is used to implement photoelectric conversion or electro-optical conversion, and a circuit structure capable of supporting functions of a transmission layer, a network layer, a data link layer, and a physical layer, such as a medium access control (medium access control, MAC) chip, is lacking in the slave device, so that OAM information and data information cannot be transmitted between the master device and the slave device in the same optical fiber based on a PON protocol. Therefore, in the scenario of optical wireless communication, how to transmit OAM information is a problem to be solved. Disclosure of Invention The embodiment of the application provides a communication device, a communication system and a communication method, which can realize the transmission of OAM information in the scene of optical carrier wireless communication.

The photoelectric conversion module is used for receiving the optical signal, converting the received optical signal into an electric signal, obtaining a first signal, and outputting the first signal to the signal splitting module. The signal branching module is used for demodulating the first signal to obtain a second signal and sending the second signal to the power driving module, wherein the second signal is a low-speed signal and is used for indicating operation, administration and maintenance (OAM) information of the second communication device. The first processing module is used for processing OAM information of the second communication device. Based on the first communication device provided in the first aspect, the signal splitting module can demodulate the electrical signal converted by the photoelectric conversion module to obtain a low-speed signal, so as to obtain OAM information, and thus, the OAM information in the optical carrier wireless communication scene can be received. In one possible implementation, the first processing module supports serial communication.

In this way, the signal can be output according to the detected condition of the actual signal, and the energy waste can be reduced. In one possible implementation, the first detection module is configured to detect a voltage or a current. In this way, level shifting of different signals can be achieved, matching the electrical performance in different circuit configurations.
