Discussion on armored optical cable by optical fiber filling paste manufacturer

Armored cable, to put it bluntly, is an optical cable with a layer of defensive "armor" wrapped in the outside world. The manufacturer of optical fiber filling paste reminds that the key of armor is to maintain the optical fiber cable to avoid being bitten by small animals, Moisture Corrosion in the body or other hazards.

Basic structure of armored cable and optical cable

In the design scheme of armored cable and optical cable, the outer tube can protect the cable from organic solvent and damage. Generally, the outer tube is made of plastic, such as high-pressure polyethylene. Between the outer waterproof sleeve and the inner protective sleeve is the armored cable, which cannot be cut, bitten and damaged by laser, such as strip steel and aluminum platinum. The raw material of armored cable can also avoid the stretching of optical cable in the whole process of cable laying. Then the protective wire sleeve is separated from the rope. Generally, the protective wire sleeve separation rope is immediately located under the armored cable and the inner protective wire sleeve, which can assist in separating the protective wire sleeve when assembling the optical cable to the RF connector or terminal equipment. Internal protective wire sleeve is a kind of raw material with defensive and flame retardant grade, which can support the whole vehicle harness of internal optical cable. The whole vehicle harness of internal optical cable includes lifting prefabricated components, fillers and other structures that can support the optical cable at the internal support point. Generally, there is a management center to improve the component support points and all optical cables. In simple technical terms, in the cable of armored cable, the buffer pipeline is closely surrounded by a layer of aramid fiber yarn, a layer of high-pressure polyethylene sleeve and a layer of corrugated thick steel plate armor. In this category, there is also a layer of gray black molar mass formula high-pressure polyethylene protective wire sleeve, which contains the protective wire sleeve from the rope.

Types of armored cables and optical cables

Armored cables and optical cables are generally divided into indoor and outdoor types. There are three types of storage: two-layer armored cable, single-sided armored cable, and unarmoured cable. Two layer cables are used in most places near shore and offshore, and no cables are used in most places of submarine cables. Single sided cables are used in places other than this extreme standard.

Armored cable and optical cable in the room

Armored cables and optical cables in the room include single-sided armored cables and two-layer armored cables and optical cables (as shown in the figure below). Universal single core armored cable the structure of optical cable in the room includes a close buffer layer optical fiber line, aromatic fluorobenzene, corrugated hose, stainless steel plate braided wire and outer protective wire sleeve. The single-sided armored cable does not include the manual braided cable with stainless steel plate, while the two-layer armored cable only includes corrugated hose and stainless steel plate braided cable.

Outdoor armored cable and optical cable

Outdoor armored cables and optical cables can be divided into light armored cables and overweight armored cables. Optical fiber filling paste manufacturers believe that under normal conditions, ultra heavy armored cables and optical cables are used at the bottom of lakes and deep seas. Unarmored cable, fiber optic cable and cable are cheaper than armored cable, fiber optic cable and steel, and aluminum is more cost-effective than Kevlar cable.
