  • FAULT LOCALIZATION METHOD AND A FAULT LOCALIZATION APPARATUS IN A PASSIVE OPTICAL NETWORK AND A PASSIVE OPTICAL NETWORK HAVING THE SAME
    Publication number: 20110255860
    Abstract: The present invention discloses a fault localization method and a fault localization apparatus in a Passive Optical Network (PON) and a passive optical network having the same. A fault localization method in PON according to the present invention comprises a) configuring an optical path of a remote node (RN) selectively by electric power being fed temporarily only when necessary, while the PON is regularly being operated as a passive network; and b) detecting a fault occurring on the selectively configured optical path by inserting a monitoring signal of an OTDR unit, which is positioned in a central office (CO), through the selectively configured optical path.
