摘要： Provided are a preamble sending method and apparatus and a preamble receiving method and apparatus. The preamble sending method includes sending a preamble containing two or more code pattern sequences, where the two or more code pattern sequences comprise a first code pattern sequence and a second code pattern sequence. That is, by enabling the preamble to support different code pattern sequences, the rapid transmission of the preamble is implemented by using functions corresponding to the different code pattern sequences, and thus the rapid equalization convergence can be performed after the rate of a passive optical network is improved, thereby improving the transmission efficiency and decreasing the processing delay. Through the preceding technical solutions, the problems in the related art that equalization time is long, transmission efficiency is reduced and processing delay is increased due to the fact that a preamble is not conducive to the convergence of an equalizer are solved.

摘要： A method for activating an Optical Network Unit (ONU) is provided, where the ONU communicates with an Optical Line Terminal (OLT) through a plurality of paths. The method includes: finding the ONU by the OLT on a path of the plurality of paths; and/or selecting one path from the plurality of paths and performs a ranging on the ONU on the selected path, by the OLT. Through this solution, the OLT finds the ONU and performs ranging on each ONU on only one of the plurality of paths, that is, does not activate each ONU on all paths, thereby quickly completing an activation process of a multi-path PON in a multi-path PON structure and improving work efficiency.
