Ethernet Passive Optical Network (EPON) must be equipped with Operations, Administration and Maintenance(OAM) features. Functions of 802.3ah OAM protocol in EPON system are Link performance monitoring, Fault detection and Fault signaling, Loopback testing. The related five types of OAMPDUs are Variable Request/Response, Information, Event Notification, Loopback Control and Organization Specific. Both OAM functions and OAMPDUs described in detail. The main functions provided by OAM are partitioned into three components: multiplexer, parser and client and control. As a part of our EPON system, the OAM sublayer components has been implemented using FPGA which can manage high speed Non-OAMPDUs and slow protocol at the same time. The OAM sublayer module and implemented its function are designed by using Xilinx PPGA. Not only the hardware block diagram but also the actually circuit are accompanied in detail. The result indicates that the data is the same as the protocol description.
