Acoustic Sensing after 50 km of Transmission Fibre using Coherent Optical Subassembly
Florian Azendorf, André Sandmann, Wolfgang Reimer +1
A coherent optical subassembly (COSA) is evaluated for coherent-correlation optical time domain reflectometry (CC-OTDR) based fibre sensing. Even though the COSA was originally des…
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…
Monitoring of Optical Networks Using Correlation-Aided Time-Domain Reflectometry with Direct and Coherent Detection
Michael H. Eiselt, Florian Azendorf, Andre Sandmann +2
We report on methods to monitor the transmission path in optical networks using a correlation-based OTDR technique with direct and coherent detection. A high probing symbol rate ca…
Simultaneous Temperature and Acoustic Sensing with Coherent Correlation OTDR
André Sandmann, Florian Azendorf, Michael Eiselt
Superimposed temperature variations and dynamic strain applied through a 400 Hz acoustic signal on a 195 m single-mode fiber section are successfully measured using a coherent corr…
Optical fiber for remote sensing with high spatial resolution
Michael Eiselt, Florian Azendorf, Andre Sandmann
The use of optical fiber as sensor as well as transmission medium for sensing data is discussed, enabling the use of optically active sensors without power supply at distances of t…
