Multi-Failure Post-Fault Restoration in Multidomain DWDM Networks
Multi-Failure Post-Fault Restoration Multidomain DWDM Networks
2015/5/25
This paper proposes an adapted crankback-enabled post-fault restoration scheme against large-area failure events in multi-domain DWDM optical network. This novel solution provides recovery and resourc...
Remotely Pumped WDM-PONs for Bidirectional 10-Gb/s Transmission with Channel Fault Monitoring
Fiber optics communications Fiber optics amplifiers oscillators
2015/5/22
WDM-PONs for 10-Gb/s bidirectional transmission are realized with REAMs as ONUs and ASE source for channel fault monitoring. The remotely pumped scheme can simultaneously boost up- and down-stream sig...
OTM- and OTDR-based cost-efficient Fiber Fault Identification and Localization in Passive Optical Network
OTM Passive Optical Network OTDR-based cost-efficient Fiber Fault
2015/5/18
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 acc...
Topology Partitioning with Fault-Tolerant Mapping
Topology Fault-Tolerant Mapping Partitioning
