The Quantitative Dependence of Transmissivity on Flexural Strain for Multimode Optical Fiber.

Abstract

Four different multimode optical fibers were tested to obtain the following correlations: 1) signal power with bend radius, 2) strain with bend radius, and 3) signal power with strain. The data are presented numerically, graphically, and mathematically. Graded index multimode and step index multimode fibers are discussed. The mechanism for the attenuation of light in optical fiber as a result of macrobending is examined. Three of the tested fibers demonstrated a consistent relationship between flexural strain and light transmissivity and could potentially be inlaid with a curved composite material system for use as the principal component in a stress or strain transducer. Keywords: Optical fibers, Fiber optics, Attenuation, Transmission loss, Macrobending, Transmissivity, Strain (mechanics). (mjm)
