Distributed Sensing of Single Mode Fibers with Correlation Techniques
Florian Azendorf, André Sandmann, Michael Eiselt +1
In this paper, we report on the development progress of correlation-based optical time domain reflectometry (OTDR). Substituting the direct detection receiver with a coherent recei…

Hollow-core fiber Characterization with Correlation-Optical Time Domain Reflectometry
Florian Azendorf, Bernhard Schmauss, Bo Shi +3
Using a Correlation-OTDR, we characterized the temperature-induced group delay variations of two nested antiresonant nodeless hollow core fibers. The temperature sensitivity of bot…
