Abstract
PURPOSE: To produce an optical fiber cable, which has its core free from water pressure or thrust and which is excellent in flexibility, by arranging a corrugated metal pipe on a core assembly and by winding a single or twisted wire concentrically on the metal pipe.
CONSTITUTION: There is arranged on an assembly 2 of optical fiber cores a corrugated pipe 7 of metal such as iron, which is coated with polyethylene. This coating is wound with a twisted wire 8, which is composed of iron wires 9, such that it is turned concentrically clockwise at a twisting pitch about thirteen times of the diameter of the corrugated pipe 7. The resultant winding is protected by an outer protecting layer 6 of PP parn. Thus, even if a tension is applied to the twisted wire 8 so that a compression is exerted between the facing twisted wires, the resultant stress can be prevented from being applied to the optical fiber assembly 2 by the action of the corrugated pipe 7 so that the increase in the transmission loss can be obviated.
