Conference Object Citation - WoS: 5Centralised Optical Monitoring of Tree-Structured Passive Optical Networks Using a Raman-Assisted Otdr(Institute of Electrical and Electronics Engineers Inc., 2007) Yüksel, Kıvılcım; Letheux, S.; Grillet, A.; Wuilpart, Marc; Giannone, D.; Hancq, J.; Ravet, G.; Mégret, PatriceMonitoring of tree-structured Passive Optical Networks from a central office is difficult to achieve using a standard OTDR. Switchable reflective elements placed at the ONU can help to discriminate between the branches. In parallel, a Raman assisted OTDR is shown to increase the dynamic range of the reflectometry measurement, thus enabling to detect more faults in the network, and especially fibre breaks after the splitter. ©2007 IEEE.Conference Object Citation - WoS: 39Optical Layer Monitoring in Passive Optical Networks (pons): a Review(Institute of Electrical and Electronics Engineers Inc., 2008) Yüksel, Kıvılcım; Moeyaert, Véronique; Wuilpart, Marc; Mégret, PatriceMotivations, challenges and requirements of optical layer monitoring in PONs are discussed. An exhaustive review of monitoring systems is given considering both Time-Division Multiplexed PON (TDM-PON) and Wavelength-Division Multiplexed PON (WDM-PON) cases. © 2008 IEEE.
