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 s ensing. Link monitoring and active detection of link tampering is demonstrated using both systems, showing how SOP-based sensing complements DAS in metro environments.
