| Abstract: | One of the key technologies of EPON is the realization of transmission convergence, including the synchronization of burst, ranging, allocation of bandwidth, frame synchronization, control of BER (Bit Error Rate), OAM (Operations, Administration and Maintenance) and so on. The design of two special chips for EPON is put forward. One is for OLT, and the other is for ONU. The designed chips achieve the main functions of transmission convergence of EPON. System performance, such as traffic delay, is simulated by using OPNET. |
