Abstract:
1. A method for sending an upstream transfer frame in a Passive Optical Network (PON), comprising: sending a preamble according to an allocated time slot; sending a burst synchronization delimiter, where in the sent synchronization delimiter, the number of non-zeros is the same as the number of zeros, and in a delimiter sequence, the number of non-zeros on odd bits is equal to the number of zeros on even bits, and the number of non-zeros on even bits is equal to the number of zeros on odd bits, wherein when the preamble is a sequence formed by a cycle of “10”, the burst synchronization delimiter is one of hexadecimal sequences in the following: A56679E0, AD4CC30F, CE99CE5E5028B41F and B3BDD310B2C50FA1; and sending a burst header, a Gigabit-Capable Passive Optical Network (GPON) Transmission Convergence (GTC) frame header, and GTC frame data.
