Embodiments of the present invention provide an access system and a communication method for an optical fiber network, which relates to the field of communications. In the present invention, a virtual ONU located on a user side is established, and an ONU control plane function, a PON MAC function, and a QoS function on an existing ONU is moved downwards to a virtual ONU. After the forgoing function modules are removed from the existing ONU, the existing ONU becomes an ONU physical converter and only has a function of converting the PON physical layer frame and the first user side physical layer frame. Therefore, a carrier does not need to maintain the ONU control plane function, the PON MAC function, and the QoS function, which lowers maintenance complexity and greatly reduces maintenance costs. |
