Real-Time Diverse Fiber Sensing Multi-Event Detection using Phase OTDR Measurements
Konstantinos Alexoudis, Jasper Müller, Sai Kireet Patri +6
We demonstrate an experimental phase optical time-domain reflectometry (OTDR) system capable of simultaneous detection and classification of various environmental events, such as w…
CC-OTDR Sequence Shaping Enabling Joint Co-directional Sensing and Communication
M. Ali Allousch, André Sandmann
CC-OTDR signal envelope shaping is introduced to reduce the impact of non-linear signal interactions on a neighboring wavelength data channel when co-propagating the probing signal…
Low-Complexity Event Detection and Identification in Coherent Correlation OTDR Measurements
Jasper Müller, Ognjen Jovanovic, Florian Azendorf +7
Pairing coherent correlation OTDR with low-complexity analysis methods, we investigate the detection of fast temperature changes and vibrations in optical fibers. A localization ac…
Remote Sensing with High Spatial Resolution
André Sandmann, Florian Azendorf, Michael Eiselt
Distributed fiber sensing based on correlation-aided phase-sensitive optical time domain reflectometry is presented. The focus is on correlation as an enabler for high spatial reso…
Pressure Wave Detection and Localization in Deployed Underground Fiber using Coherent Correlation OTDR
Florian Azendorf, André Sandmann, Michael Eiselt
A deployed fiber with in-house and underground sections is interrogated with a coherent correlation OTDR. The origin and propagation speed of a hammer-generated pressure wave in th…
