Abstract:
1. A method for synchronization detecting in an Ethernet Passive Optical Network, comprising: obtaining, by a synchronizer, M characters sequentially by getting a character from every other Q a check information bits in a continuous bit stream, wherein the Q is a number of bits of a check information block and the Q is 64, wherein the characters is 2 bits for synchronization and the characters comprises “00”or “11”; determining, by the synchronizer, whether a sequence formed by the obtained M characters is the same as a predetermined synchronization character sequence {Tj} to determine whether the synchronization succeeds; setting, by the synchronizer, locations of the M characters as locations of synchronization headers of M check information blocks, wherein the synchronization character sequence {Tj } satisfies the following conditions:
