Abstract: The present invention discloses a message transmission method, an apparatus, and a system. The method includes: obtaining physical layer operation, administration and maintenance information between an optical line terminal and an optical network unit; fragmenting the physical layer operation, administration and maintenance information, to obtain multiple fragments; generating a first message, where the first message includes: a first message type identifier field, used to identify a type of the first message; a message length field, used to identify a length of a fragment carried in the first message; an action indication field, used to identify whether the fragment carried in the first message is the last fragment; a first fragment sequence number field, used to identify a sequence number of the fragment carried in the first message; and a message content field, used to carry a fragment in the multiple fragments; and sending the first message.

Abstract: The present disclosure relates to passive optical network (PON) systems, optical line terminals (OTLs), and optical network units (ONUs). One example PON system includes an OLT and at least two ONUs. The OLT and the ONUs exchange data on one downstream channel and two upstream channels. The OLT sends downstream data to each ONU on the downstream channel, where the downstream data includes an upstream bandwidth grant used to control each ONU to send upstream data. Each ONU receives the downstream data on the downstream channel, and sends the upstream data on a first upstream channel or a second upstream channel based on the upstream bandwidth grant included in the downstream data. The OLT receives, on the first upstream channel and the second upstream channel, the upstream data sent by each ONU, where a registration function is disabled on the first upstream channel, and enabled on the second upstream channel.
