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.
