This training session was organised as part of the EU-funded SUBMERSE project, which explores sensing capabilities of existing submarine optical fiber networks for research applications.
Purpose of this training session
The training session introduces you to data recording, measurement, and analysis methods of State of Polarization (SoP) in optical networks. It will:
- provide technical insights into SoP and its relation to sensing on deployed fiber cables;
- support the implementation and validation of sensing devices in the SUBMERSE project.
Target audience
Optical networks and telecommunications operators and vendors; researchers in earth sciences and geophysics.
Requirements
None or basic knowledge of SOP changes recording and analysis methods. Basic experience in analysis of data generated by sensing network.
Session outline
- Introduction
- Fundamentals of measuring changes of the State of Polarization (SOP) with Novoptel PM 1000
- Demo of PM1000 GUI
- Demo of SoP recording and analysis with MATLAB
- Case study: SOP data analysis for seismic events monitoring
Learning objectives
With this training session, you will be better positioned to:
- define State of Polization through key correlated concepts and models of visualization
- list causes and effects of polarization changes
- describe different types of SOP measurement methods, with respective limitations
- recognize recording types with PM1000
- analyse SOP data using MATLAB
- explain benefits of using both Full-Stokes and PBS-based polarimeters for earthquake monitoring.
