Continuous Fiber Sensing over Field-Deployed Metro Link using Real-Time Coherent Transceiver and DAS
- 2022
-
Ingår i: 2022 European Conference on Optical Communication, ECOC 2022. - 9781957171159
-
Konferensbidrag (refereegranskat)abstract
- We use an FPGA-based real-time coherent transceiver prototype with continuous μs-level state-of-polarization readouts and a commercial DAS system to perform fiber sensing. Link monitoring and active detection of link tampering is demonstrated using both systems, showing how SOP-based sensing complements DAS in metro environments.

Field Trial of FPGA-Based Real-Time Sensing Transceiver over 524km of Live Aerial Fiber
- 2023
-
Ingår i: Optical Fiber Communication Conference, OFC 2023. - 9781957171180
-
Konferensbidrag (refereegranskat)abstract
- We perform fiber sensing over a 524 km live network using a real-time coherent transceiver prototype. Polarization and length changes from the link consisting exclusively of aerial fiber wound around high-voltage power cables are continuously monitored.

Ingår i: 2022 Optical Fiber Communications Conference and Exhibition, OFC 2022 - Proceedings. - 9781943580071
-
Konferensbidrag (refereegranskat)abstract
- We perform parallel continuous measurements of deployed SDM fibers using real-time coherent receivers implemented on FPGAs. Fast readouts enabling real-time tracking of the DSP implementation, showing that coupled-core fibers are compatible with real-time DSP implementations.

Real-Time Monitoring of Cable Break in a Live Network using a Coherent Transceiver Prototype
- 2024
-
Ingår i: Optical Fiber Communication Conference, OFC 2024. - 9781957171326
-
Konferensbidrag (refereegranskat)abstract
- We monitor a 524-km live network link using an real-time FPGA-based sensing-capable transceiver prototype during a human-caused cable break. Polarization sensing data shows minute-level potential break warning precursors, offering outage mitigation prospects.

Real-Time Transmission over 2x55 km All 7-Core Coupled-Core Multi-Core Fiber Link
- 2022
-
Ingår i: Optical Fiber Communication Conference, OFC 2022. - 9781557524669 - 9781557528209
-
Konferensbidrag (refereegranskat)abstract
- We demonstrate the first transmission experiment using 7-core coupled-core fiber with in-line coupled-core multi-core amplifiers and real-time DSP. The real-time DSP is implemented using a single FPGA that performs MIMO processing across all 7 cores.

Transoceanic Phase and Polarization Fiber Sensing Using Real-Time Coherent Transceiver
- 2022
-
Ingår i: Optical Fiber Communication Conference, OFC 2022. - 9781557524669 - 9781557528209
-
Konferensbidrag (refereegranskat)abstract
- We implement a real-time coherent transceiver with fast streaming outputs for environmental sensing. Continuous sensing using phase and equalizer outputs over 12800 km of submarine cable enabled time resolved interferometry in broad spectral range of 10 mHz-1 kHz.
