Acoustic Sensing with Correlation and Coherent Detection using an Integrated Coherent Transceiver
André Sandmann, Florian Azendorf, Saif Alnairat +1
Fiber optic sensing is becoming an important means to physically secure today's network infrastructure. However, a network-wide deployment of the monitors will require cost reducti…
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…
