Exploring Geophysical Applications For Distributed Acoustic Sensing (DAS) Using A Flexible Interrogator Research Platform

Autor: E. Kolltveit, Andreas Wuestefeld, Y. Heggelund, K. Midttømme, Matthew Wilks, P. Thomas

Publikováno v: Proceedings.

DAS continues to be a promising and cost-effective technology for carbon storage monitoring applications including systems that monitor geological changes using active seismics, and also for passive mode operations, e.g. the monitoring of microseismi

Initial Results from the Field on the Use of DAS as a Viable Microseismic Monitoring System of CCS Sites

Autor: Volker Oye, Matthew Wilks, P. Thomas, Andreas Wuestefeld, E. Kolltveit

Publikováno v: EAGE/SEG Research Workshop 2017.

In outdoor field-tests where a single optical fibre cable is used to make DAS recordings of hammer shots, coherent seismic arrivals are observed at up to 32 m from the hammer points with frequencies up to 600 Hz. Recording at higher sampling rates an

Measurement of the differential group delay in installed optical fibers using polarization multiplexed solitons

Autor: Magnus Karlsson, E. Kolltveit, Peter A. Andrekson, J. Brentel, B. Bakhshi, Jonas Hansryd, B.K. Olsson

Publikováno v: IEEE Photonics Technology Letters. 11:593-595

We experimentally demonstrate a new technique for measurement of the differential group delay (DGD) in optical fibers using polarization-division multiplexed (PDM) solitons: the change in the separation of orthogonally polarized solitons propagating

Polarization-division multiplexed solitons in optical fibers with polarization-mode dispersion

Autor: Xiupu Zhang, Peter A. Andrekson, E. Kolltveit, Magnus Karlsson

Publikováno v: IEEE Photonics Technology Letters. 10:1742-1744

We point out that the use of polarization-division multiplexed solitons is only preferable to a copolarized pulse train only if the system is interaction-limited and the polarization-mode dispersion (PMD) is sufficiently weak. If the PMD is stronger,

1.6 Tb/s (40×40 Gb/s) transmission over 1200 km of field-deployed dispersion-managed fiber

Autor: Michael Sauer, S. Ten, S. Colby, D. Dalgoutte, D. Witzel, J. Ferner, E. Kolltveit, Jason Hurley

Publikováno v: Journal of Lightwave Technology.

We demonstrated 40/spl times/40 Gb/s all-Raman NRZ transmission over 1200 km of field-deployed dispersion-managed fiber. Precise dispersion slope matching and low temperature sensitivity eliminated the need of per-channel and dynamic dispersion compe

Soliton frequency-guiding by UV-written fiber Fabry-Perot filter in a 2 x 5 Gb/s wavelength-division multiplexing transmission over transoceanic distances

Autor: Isabelle Riant, F. Pitel, Olivier Audouin, B. Biotteau, P. Sansonetti, Jean-Pierre Hamaide, P. Brindel, E. Kolltveit, E. Brun

Publikováno v: IEEE Photonics Technology Letters. 7:1498-1500

We report the first experimental demonstration of frequency-guiding of soliton pulses by a UV-written photosensitive fiber filter in a multichannel system. Error free transmission at 2/spl times/5 Gb/s (bit error rate

Single-wavelength 40 Gb/s soliton field transmission experiments over 400 km fibre without in-line control

Autor: B. Bakhshi, Per Olof Hedekvist, Jonas Hansryd, Magnus Karlsson, Peter A. Andrekson, J. Brentel, Bengt-Erik Olsson, E. Kolltveit, Jianqiang Li

Publikováno v: Scopus-Elsevier

We report single-wavelength 40-Gbit/s soliton transmission over 400-km installed fiber lines in Sweden. Both polarization-division multiplexed and parallel solitons were transmitted. The system performance is dominated by the polarization-mode disper
