  • Method of molding a flexible tube of low thermal longitudinal coefficient of expansion
    Patent number: 4871499
    Abstract: A tube for protecting and guiding an optical fiber is constituted by two tubes which are co-extruded and then stretched. The inner tube thus acquires a reduced coefficient of linear expansion, which is closer to that of glass. The outer tube protects the inner tube from fibrils appearing on its surface.
