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.Article Citation - WoS: 25Novel Monitoring Technique for Passive Optical Networks Based on Optical Frequency Domain Reflectometry and Fiber Bragg Gratings(Institute of Electrical and Electronics Engineers Inc., 2010) Yüksel, Kıvılcım; Wuilpart, Marc; Moeyaert, Véronique; Mégret, PatriceAn efficient monitoring method having a very short measurement time (a few seconds) is proposed. The equal-length branches can be effectively monitored, but also the information of temperature at any place in the network can be obtained. The feasibility of this technique is experimentally demonstrated. © 2010 OSA.Article Citation - WoS: 35Complete Analysis of Multireflection and Spectral-Shadowing Crosstalks in a Quasi-Distributed Fiber Sensor Interrogated by Ofdr(Institute of Electrical and Electronics Engineers Inc., 2012) Yüksel, Kıvılcım; Moeyaert, Véronique; Mégret, Patrice; Wuilpart, MarcWe present the analysis of a quasi-distributed fiber sensor based on the concatenation of identical low-reflective fiber Bragg gratings (FBGs) taking into account both multireflection and spectral-shadowing crosstalks. This allows obtaining more realistic values of the design parameters such as the maximum number of sensing points, the reflectivity of the gratings, and the distance between the sensing points. © 2001-2012 IEEE.
