This document provides a summary of fiber optic sonobuoy development through FY76. Optical fibers were incorporated into developmental sonobuoy cables with attenuations as low as 4.8 dBkm at 0.85 micrometers and 1.8 dBkm at 1.05 micrometers. A 0.5-dBkm attenuation increase was observed at a hydrostatic pressure of 48 MPa 7 kpsi. Less than 1-dBkm attenuation increase was observed for tension and bending stresses. Discussions of cable development optical, mechanical, and environmental cable tests fiber and link studies and measurement techniques are presented. It is recommended that observed deficiencies be reduced to operationally acceptable levels through continued fiber optic sonobuoy cable development. Author
