Paper Abstract

We report underwater explosion test results of the effect of shock wave pressure on an optical cable link in a fiber- optic velocimeter. The shock wave induced Doppler frequency shifts in the optical carrier transmitted in an optical cable link were measured. Two experimental configurations were tested: (1) optical cable arranged with its axis parallel to the wave front of the shock wave and (2) optical cable arranged with its axis perpendicular to the wave front of the shock wave. Results from both case indicated moments of signal fading due to dynamic flexing on the optical fiber resulting in optical power loss and polarization changes. In addition, the shock wave front moving along the fiber cable may have generated a dynamic axial strain on the optical fiber and caused a Doppler shift in the optical carrier similar to that from a moving target.
