<p>The present invention discloses a DOCSIS protocol-based access method, apparatus, and system, and relates to the field of communication network technologies, so that a topological structure of a passive optical network is supported between a DOCSIS CMTS and an optical node, and system efficiency is improved. In the present invention, a first PON physical layer module is disposed inside or outside a CMTS device; the CMTS device receives DOCSIS protocol-based data, converts the DOCSIS protocol-based data into PON physical layer format-based data by using the first PON physical layer module, and sends the PON physical layer format-based data to a CMC through an optical distribution network; and the CMC receives the PON physical layer format-based data, converts the PON physical layer format-based data into DOCSIS physical layer format-based data, and sends the converted data to a terminal device. The solution provided by the present invention is applicable to a DOCSIS system.</p> |
