Abstract: A GE-PON (Gigabit Ethernet Passive Optical Network) apparatus includes a 2×N splitter, an OLT (Optical Line Terminal) connected to the 2×N splitter via a first path line or a second path line, and a switching unit for switching the first path line or the second path line upon receiving a predetermined control signal. An ONU (Optical Network Unit) generates a switching request according to a signal environment and transmits the generated switching request to the OLT.

Abstract: A method for transmitting security data in an Ethernet PON (Passive Optical Network) system is provided. The method includes the steps of: a) creating a frame comprised of a data field for encrypting the security data, a key information field for storing key information used for decrypting the encrypted data of the data field, and a security frame, wherein the security frame includes an ONU ID (Identifier) field for indicating ONU ID information identified by an ONU having the destination user, and a user ID field for indicating a security ID identified by the destination user; and b) transmitting the created frame.

Abstract: Ethernet Passive Optical Network (PON) system is provided and includesan Optical Line Termination (OLT) and a plurality of Optical Network Units (ONUs) connected to the OLT, and the system implements a Peer-to-Peer (P2P) transmission between ONU-side objects controlled by the OLT. A PON tagging Ethernet frame for the P2P transmission includes a Destination Address (DA) field, a Source Address (SA) field, a mode field indicating an emulation mode, and a PHY_ID field indicating identifiers of the ONU-side objects, and a data field.
