Abstract

PURPOSE:To make the size of termination of a submarine cable small, by arranging the core of optical fibers in spiral for sealing construction. CONSTITUTION:An optical fiber core 4 is wound in spiral at the side of a cylinder 8' made of metal and a layer of curable resin 7 is provided at the outside for a sealing construction. Or a spiral groove 12 is provided at the side of the cylinder 8'. A core 4 is wound in the groove and sealing construction is achieved similarly. Both ends of the core 4 are led from both ends of the cylinder 8' in any case. Thus, the airtight construction in which the optical fiber core is arranged in the resin in spiral, has small possibility for the movement of the core under a hydrostatic pressure, allowing to achieve the small sized termination for the submarine optical cable. As the material of the cylinder 8', ceramic and resin rubber as well as metal can be used.
