Ultra-Remote Fibre Optic Acoustic Sensing Array based on RF Modulation

RF modulation locking techniques applied to fibre Fabry Perot interferometers enable array based sensitive detection over very long distances in a single fibre. We present results showing multi-channel operation in a 120 km loop using this technique.
