Real-time diagnostics on a QKD link via QBER Time Series Analysis
G. Maragkopoulos, A. Mandilara, T. Nikas +1
The integration of QKD systems in Metro optical networks raises challenges which cannot be completely resolved with the current technological status. In this work we devise a metho…
Linking distributed and integrated fiber-optic sensing
Daniel C. Bowden, Andreas Fichtner, Thomas Nikas +7
Distributed Acoustic Sensing (DAS) has become a popular method of observing seismic wavefields: backscattered pulses of light reveal strains or strain-rates at any location along a…
Sensitivity kernels for transmission fiber optics
Andreas Fichtner, Adonis Bogris, Daniel Bowden +6
Fiber-optic sensing technologies based on transmission offer an alternative to scattering-based Distributed Acoustic Sensing (DAS). Being able to interrogate fibers that are thousa…
Introduction to phase transmission fibre-optic sensing of seismic waves
Andreas Fichtner, Adonis Bogris, Thomas Nikas +6
This manuscript is concerned with phase changes of signals transmitted through deforming optical fibres. As a first result, it establishes an exact relation between observable phas…
Microwave frequency dissemination systems as sensitive and low-cost interferometers for earthquake detection on commercially deployed fiber cables
Adonis Bogris, Christos Simos, Iraklis Simos +6
We experimentally demonstrate a microwave frequency dissemination system operating as a sensitive interferometric sensor of seismic waves on commercially deployed fiber networks in…
Static Skew Compensation in Multi Core Radio over Fiber systems for 5G Mmwave Beamforming
Thomas Nikas, Evangelos Pikasis, Dimitris Syvridis
Multicore fibers can be used for Radio over Fiber transmission of mmwave signals for phased array antennas in 5G networks. The inter-core skew of these fibers distort the radiation…
Compensation of Multicore Fiber Skew Effects for Radio over Fiber mmWave Antenna Beamforming
Thomas Nikas, Evangelos Pikasis, Sotiris Karabetsos +1
In 5G networks, a Radio over Fiber architecture utilizing multicore fibers can be adopted for the transmission of mmwave signals feeding phased array antennas. The mmwave signals u…
