    Abstract: The present invention discloses a communication method, including: downloading, from a server according to a user instruction, a technical specification indicated by the user instruction, and sending the technical specification to an optical network unitONUby using an out-of-band management channel; configuring the technical specification; delivering a control message to the ONU by using the out-of-band management channel, to instruct the ONU to configure the technical specification; and communicating, based on a mode supported by the technical specification, with the ONU by using an in-band data channel. According to the solution, a physical layer or a MAC layer may be dynamically reconfigured, and different software may be used to define PON systems of different standards according to a user's requirements and an application scenario, with no need to replace hardware. This greatly increases flexibility during PON deployment and reduces costs of deployment and maintenance.
