Self-supporting light-emitting optical cable and manufacturing method thereof

Abstract

The invention discloses a self-supporting light-emitting optical cable and a manufacturing method thereof. The self-supporting light-emitting optical cable includes a reinforced inner frame, a heat-shrinkable sleeve, a plurality of optical fibers, a waterproof layer, a metal shielding layer, a steel strand, A bulletproof silk braiding layer, a luminescent layer and a flame-retardant transparent sheath layer; the surrounding side of the reinforced inner frame is formed with a plurality of placement positions arranged at intervals, and the reinforced inner frame includes an outer carbon fiber frame and an inner metal frame , the inner metal frame is embedded in the formed outer carbon fiber frame; through the use of heat-shrinkable sleeves and foam materials, multiple optical fibers can be firmly fixed on the reinforced inner frame, effectively preventing the occurrence of disconnection , and by setting waterproof layer, metal shielding layer, steel strand, bulletproof wire braided layer, luminous layer and flame-retardant transparent sheath layer, this product has waterproof, shielding, tensile resistance, strong load-bearing, self-illumination and resistance Combustion and other characteristics, the overall performance of the product is better.

Description

technical field [0001] The invention relates to the technology in the field of optical cables, in particular to a self-supporting light-emitting optical cable and a manufacturing method thereof. Background technique [0002] Driven by multiple benefits such as 3G network construction, FTTH (fiber-to-the-home) implementation, triple-network integration pilot, village-to-village project in the west, and "fiber into copper retreat", China's optical fiber and cable industry has a good momentum of development, and my country has become the world's largest The main fiber optic cable market and the world's largest fiber optic cable manufacturing country, and has achieved remarkable achievements. [0003] A fiber optic cable is a communication cable consisting of two or more glass or plastic optical fiber cores within a protective cladding covered by a plastic PVC outer sleeve. Signal transmission along the internal fiber optics typically uses infrared light. [0004] Due to the si...
