SENSING NET targets to enhance the value of the already deployed optical fiber infrastructure for telecommunications by introducing fiber sensing technologies to explore novel potential applications, assuring additional revenues for networking-service providers, fiber network owners and operators by developing new promising applications and services.

The alternative usage of fiber networks can include not only the control and supervision of the telecom infrastructure integrity, but also the distributed diagnostics and surveillance in smart city scenarios, the monitoring of traffic and facility safety in railways and motorways; the leak detection in pipelines; the detection of large breaches and damages in civil structures. SENSING NET will exploit TLC-compatible sensing strategies to provide a real time, pervasive monitoring of mechanical, thermal and electrical phenomena. This sensing strategy will be performed both considering already deployed fiber links and newly installed fibers associated to utilities networks.

The project outcomes could support institutional decision makers in fields ranging from the civilian to the environmental protection, for the prompt detection of structural faults, and hazards.

SENSING NET is part of Spoke 1 – Pervasive and Photonic Network Technologies and Infrastructures

Coexistence of Sensing and TLC Signals (WP2):
  • Examination of industry standards for access and metro/regional networks;
  • Identification of requirements for signal power, optical losses, and wavelength bands;
  • Collaboration on potential scenarios, including interferometric sensing in PON networks;
  • Deployment of interferometric and DSP-based sensing techniques for building and earth hazard monitoring.

Optical Sensing using TLC Fiber Networks (WP3):
  • Analysis of PON infrastructure peculiarities;
  • Identification of a field trial for testing sensing solutions in building structures and fiber health.
  • WP2: the first DL was released. Study on coexistence with GPON standard and OPEN FIBER PON infrastructure.
  • WP3: It has been identified a specific PON connecting the POP of Opera with several housing units in San Donato Milanese, characterized by a distance of around 12.5 km. It has been organized in December the first survey in POP of OF and in the building where should be installed FOS technology. A second inspection was organised with the building administration. As a preliminary result, it has been proposed the C band as a working window for sensing signal wavelenght within GPON architecture.
  • WP4: cascade call- call closed, is being evaluated by CNR.

Collaboration proposals:

SENSING NET project concerns the application of particular optical sensing solutions (for example interferometric architectures) to the optical fiber infrastructure for telecommunications and to the networks supporting utilities. For this reason, SENSING NET represents a project of strong synergy with RIGOLETTO.

In particular, the research proposed in the focused SENSING NET project are complementary to the activities relating to telemetry foreseen in WP4 of the structural project.

For any proposal of collaboration within the project please contact the project PI.
