Fiber Optic Sonobuoy Cable Development Fy76. Electro-Optical Components for Data Transfer between Deep Sumberged Acoustic Sensors and Surface Buoys.
Abstract
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 dB/km at 0.85 micrometers and 1.8 dB/km at 1.05 micrometers. A 0.5-dB/km attenuation increase was observed at a hydrostatic pressure of 48 MPa (7 kpsi). Less than 1-dB/km 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)
