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…
