Abstract

The attenuation of light transmittance through a plastic optical fiber in the range of visible light is governed by light scattering loss. In this paper, the possibility of decreasing scattering loss in poly(methyl methacrylate) (PMMA), which is one of the core materials of a plastic optical fiber, is discussed. The light scattering loss of the PMMA glass prepared from a contaminant-free monomer depended on the conditions of polymerization and heat-treatment. The authors succeeded in preparing the PMMA glass with a light scattering loss lower than the value, 14 dB/km, which was reported as the theoretical limitation at 633 (nm)-wavelength in the fluctuation theory for structureless liquids.
