Paper Abstract

With continuous increasing of demand for the bandwidth in the side of user, building broad-band access network becomes conspicuous. Passive optical network (PON) based on Asynchronous Transfer Mode (ATM), i.e. APON is considered as an ideal solution for the optical access network (OAN). The paper briefly introduces APON access System and it's delaminating. Basing on it, paper focuses on discussing distributed sample de-scrambling in the PON transmission layer. The node of distributed sample de-scrambling is the synchronization between Psedo Random Bit Sequence (PRBS) of transmitter with PRBS of receiver. In term of ITU-T G.983 this paper make logistic analysis to de-scrambling and give circuit for reference. For the more this paper put forward the feasible solution to the distributed sample de- scrambling which implements by FPGA. The figure of Functional Blocks that used for the FPGA design is also provided.
