OTM- and OTDR-based cost-efficient Fiber Fault Identification and Localization in Passive Optical Network

Not Accessible

Your library or personal account may give you access

Abstract

PON monitoring based on combined Optical Time Domain Reflectometry (OTDR) and Optical Transceiver Monitoring (OTM) is presented. The results on a 25-km 1:32 PON prove the concept and show ~0.02 dB accuracy with theoretical values.
