Optical fiber cable

Abstract

The invention relates to an optical fiber cable comprising a core having at least one helical groove in its periphery, at least two assembled-together flexible tubes placed in the groove, each flexible tube containing a plurality of optical fibers, and a flexible material placed between the flexible tubes and the bottom of the groove. The core is surrounded by means for providing protection against external agents, e.g. an aluminum tape or a tube of plastic material. Stiffening means such as armoring wires surround the assembly. The present invention relates to an optical fiber cable, more particularly to an optical fiber cable of compact structure comprising a grooved core having packets of optical fibers placed in its grooves.
