Paper Abstract

We designed and constructed a 400km interrogated fiber-optics hydrophone (FOH) array for the bottom mounted applications. The experimental results show that the phase noise level of the remote array is -97dB re 1rad/sqrt(Hz) @1kHz, the maximum time division multiplexing (TDM) crosstalk level is -54dB, the wavelength division multiplexing (WDM) crosstalk level is better than -73dB and the signal correlation between two sensors is better than 0.98. The results demonstrate that the performance of this remote array has reached to an acceptable high level, so this architecture would be of great importance in the practical applications.
