Abstract
We present and demonstrate a Brillouin Optical Time Domain Analysis (BOTDA) based long range sensor network with remote switching. Two different 5 km long sections were monitored alternatively by using a fast remotely controlled and optically powered up optical switch. The sensed fibers were located 10 km away from the interrogation unit. The BOTDA unit uses a simplified configuration to reduce the sensor network costs. Proof-of-concept experiments were carried out verifying the capacity of the proposed system.
