Abstract
Provided is a passive optical network (PON) providing system of an Ethernet-based packet transport layer (PTL) scheme, including: a connection management server to manage a unified PTL connection overall over the network by establishing a PTL connection between an optical network unit (ONU)/optical network terminal (ONT) of a customer termination of one party and an ONU/ONT of a customer termination of another party, and by applying a PTL-PON scheme to a PON section between the ONU/ONT and an optical line termination (OLT); an OLT to manage a connection of a received packet, and to convert a format of the packet according to a transmission direction of the packet and thereby transmit the packet; and an ONU/ONT becoming an end point of the PTL connection to convert the format of the packet according to the transmission direction of the received packet and to thereby transmit the packet to a customer terminal or the OLT.
