Abstract: 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.

Abstract: Provided are a data processing method and apparatus for a Passive Optical Network (PON) system and a PON system. The method includes: a first partial bandwidth is allocated to a first Optical Network Unit (ONU) within a first time window, the first ONU having completed registration and being in a working state; and a first data frame from the first ONU is received within a time corresponding to the first partial bandwidth, and a second data frame from a second ONU is detected within the first time window, the second ONU having not completed registration.

Abstract: An optical-electrical receiving and transmitting method and apparatus, as well as an optical-electrical transceiving method and device and an optical-electrical transceiver are provided. The optical-electrical transceiving processing method may include: in a reception direction, a received optical signal is split into multipath optical signals, the multipath optical signals are processed into multipath parallel electrical signals, and the multipath parallel electrical signals are converted into a single-path serial electrical signal; in a transmission direction, a received single-path serial electrical signal, which is to be transmitted, is converted into multipath parallel electrical signals, then the multipath parallel electrical signals are processed into multipath optical signals, and finally the multipath optical signals are combined into a single beam of optical signals.
