APPARATUS AND METHOD FOR DUPLEXING GIGABIT ETHERNET (R) PASSIVE OPTICAL NETWORK SYSTEM, AND FRAME FORMAT FOR CONTROLLING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a duplex apparatus for switching a path in a gigabit Ethernet (R) passive optical network (GE-PON) system, and a frame format for controlling the same.;SOLUTION: The duplexing apparatus comprises a 2×N splitter, and an optical subscriber network apparatus (ONU) connected to the 2×N splitter via a first path or a second path for receiving a predetermined control signal, generating a switching request to an optical path terminal device (OLT) having a switching portion for switching the first path and the second path and a signal environment, and transferring the generated switching request to the OLT.;COPYRIGHT: (C)2004,JPO
