Conference Object Citation - WoS: 14Citation - Scopus: 14An Overview of the Recent Advances in Fbg-Assisted Phase-Sensitive Otdr Technique and Its Applications(IEEE, 2020) Yüksel, Kıvılcım; Koçal, Ertunga Burak; Jason, Johan; Wuilpart, Marc; Sainz, Manuel Lopez-AmoIn this paper, we discuss the operation principles, sensing mechanism, challenges and application areas of FBG-assisted phase-sensitive optical time-domain reflectometry. A special emphasis is given to the interrogation of fiber Bragg grating arrays for vibration sensing application. Results obtained by different research groups are compared in terms of performance characteristics and future perspectives. Recent progress obtained through our research collaboration are also presented. In particular, the detrimental spectral shadowing effect and multiple reflection crosstalk are analysed and mitigation techniques are proposed. © 2020 IEEE.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: 30Optical Frequency Domain Reflectometry: a Review(Institute of Electrical and Electronics Engineers Inc., 2009) Yüksel, Kıvılcım; Wuilpart, Marc; Moeyaert, Véronique; Mégret, PatriceIn this paper, we discuss the operation principles, challenges and application areas of optical frequency domain reflectometry technique. A review of OFDR systems is given considering both Incoherent-OFDR and Coherent- OFDR groups. Results obtained by different research groups are compared in terms of performance characteristics, and future perspectives. Recent progresses obtained within our laboratory are also presented. ©2009 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.
