Ethernet Passive Optical Networks (GEPON or EPON) is the leading technology being used in FTTx (FTTH) deployments. PON is different than other optical network topologies in that it is a Point to Multi-Point (P2MP) topology.
The customer’s system (Optical Network Unit - ONU) determines what packets are for that customer. All other packets are discarded. The PON current standards have defined downstream data rates up to 1.25Gbps.
IEEE 802.3ah. EPON or GEPON (Ethernet PON) is an IEEE/EFM standard for using Ethernet for packet data.
