Abstract
PURPOSE: To prevent application of uneven side pressure upon an optical fiber by providing the cushion layer comprising filling liquid such as oil or the like in foam- or sponge form material.
CONSTITUTION: The outer side of an optical fiber 1 which is applied with the clad of the thin layer of urethane, Kynar, or epoxy is covered with the cushion layer 5 of songe- or foam-form material filled with liquid such as oil or the like. If the layer 5 is covered with a secondary convering 3 of metal or plastic material, the optical fiber core is formed. The constitution of small compression against water pressure of this layer 5 prevents the shrinkage and deformation of the covering 3, obviates the application of uneven side pressure to the optical fiber 1 and provides the optical fiber core best suited for submarine cable or the like.
