Flexible metal armored field operation optical cable

Abstract

The invention discloses a flexible metal armored field operation optical cable and a manufacturing method, and relates to the technical field operation optical cable. The flexible metal armored field operation optical cable comprises a cable core layer, a single optical fiber or a plurality of optical fibers are arranged in the cable core layer, the cable core layer is sequentially wrapped by a spiral armored pipe, a steel wire rope strand armored layer and an outer protective layer, the thickness of the spiral armored pipe is 0.15 mm-0. 3mm, the spiral gap is 0.05 mm-0. 15mm, the steel wire rope strand armored layer is formed by mutually twisting a plurality of steel wire rope strands, the twisting pitch is 30mm-70mm, and the steel wire rope strands can optionally adopt any one, any two or any three of a single-strand rope, a double-twisted rope with the lay length of 10mm-20mm and a three-twisted rope. The double-armored structure design of the spiral armored pipe and the steel wire rope strand armored layer is adopted, the problems that an armored optical cable is high in rigidity and low in flexibility are solved, the spiral armored pipe is similar to a metal spring due to the existence of gaps, rigidity of a stainless steel pipe is avoided, the metal pipe has the characteristic of flexibility, the steel wire rope strand armored layer is formed by twisting a plurality of thin steel wires, and certain flexibility can be achieved while the strength is guaranteed.

Description

technical field [0001] The invention relates to the technical field of field optical cables, in particular to a flexible metal armored field optical cable. Background technique [0002] The field optical cable is a metal-free optical cable specially designed for use in field operations and complex environments that require rapid wiring or repeated retractable use. Easy to bend; oil-resistant, wear-resistant, flame-retardant, and suitable for a wide temperature range. It is suitable for rapid wiring or repeated retraction of military field communication systems; radar, aviation and ship wiring; oil fields, mines, ports, live TV broadcasts, emergency repairs of communication lines and other harsh conditions. Most of the traditional field optical cables use metal armor to resist the impact and damage of the external environment through the metal armor layer. However, although the metal armor layer improves the strength of the optical cable, it also increases the toughness of t...

Most of the traditional field optical cables use metal armor to resist the impact and damage of the external environment through the metal armor layer. However, although the metal armor layer improves the strength of the optical cable, it also increases the toughness of the optical cable. Problems with bending and difficult routing
