Abstract

The invention discloses the manufacturing method of a submarine airtight steel cable containing a communication optical fiber. The method comprises the following steps of drawing a steel wire in a high strength mode; carrying out tempering processing; twisting a steel rope core strand; twisting the communication optical fiber and the steel rope core strand; wrapping and twisting multiple layers ofsteel wires on the external portion of the twisted communication optical fiber and steel rope core strand in a layered mode so as to form a cable, wherein an interlayer gap is filled with high density plastics and a cable paste is uniformly smeared on a surface; and then cladding an external protection layer. The method has advantages that the communication optical fiber and a high strength steelrope are combined to form the steel cable containing the communication optical fiber so that anti-compression and tensile resistance performance of the communication optical fiber can be enhanced andfracture and other phenomena can be avoided; and a high density rubber is filled in and multiple protection layers are coated so that the severe environment confrontation performance of the communication optical fiber is greatly increased.

Description

technical field [0001] The invention relates to the technical field of manufacturing submarine sealed steel cables, in particular to the manufacturing technology of submarine sealed steel cables containing communication light. Background technique [0002] Fiber optic cables consist of a core, cladding and outer protective covering. The core and the higher-index shell are usually made of high-quality silica glass, but plastic fibers are now also available. However, if the fiber is bent too sharply or bumped, there is a danger of breaking it. And because the connection between the two ends of the fiber requires very precise alignment, it is also difficult to resplice the broken fiber. This makes the application of communication optical fiber an obstacle that is difficult to overcome. Contents of the invention [0003] The object of the present invention is to provide a manufacturing method of a submarine sealed steel cable containing communication optical fibers. [000...
