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 embodiments of the present invention disclose an External Cavity Laser (ECL), relate to the field of Wave Division Multiplexing-Passive Optical Network (WDM-PON) technology, and effectively solve a problem of unstable output optical power of the ECL caused by polarization dependence. The ECL includes a gain medium, a filter, and a Faraday Rotator Mirror (FRM). The gain medium, the filter and the FRM constitute an oscillation cavity, and light emitted by the gain medium oscillates back and forth in the oscillation cavity.
