Abstract

We present a novel Brillouin time domain analysis configuration for monitoring parallel fiber networks. By employing branch length manipulation, the new probe pulse arrangement improves the system dynamic range compared with a previously reported approach that uses a single pair of pump and probe pulses. This technique is promising in parallel fiber sensing that enhances the system reliability.
