Differences between armored fiber optic patch cords and ordinary fiber fiber optic patch cords

Armored fiber patch cord, also known as steel armor fiber patch cords, are a special kind of fiber patch cords which are coated with a protective "armor" sleeve of spiral stainless steel. Armored fiber patch cord is a new type of optical fiber patch cord, which can be used in the machine room and in various harsh environments.

Compared with the common fiber patch cord, The armored fiber optic patch cord is protected by stainless steel hose and has higher compressive and tensile properties. The common patch cord fiber cable is mainly composed of compact fiber, aramid yarn and outer sheath, while the armored fiber cable adds a layer of stainless steel armor between the two layers of compact fiber and aramid yarn. Without affecting the optical properties of the optical fiber itself, the anti-lateral pressure ability of the optical fiber is greatly improved, which can prevent the damage caused by mechanical forces. It's impact-resistant and rat-bite-resistant.

Although armored fiber optic patch cords add stainless steel casing, this does not affect their flexibility at all. By comparing the bending performance of the following armored fiber optic patch cords with ordinary products, it can be seen that the usable bending diameter of the armored fiber optic patch cords is up to φ5mm, which is half of the conventional products. As a result, it has great flexibility even when used in limited Spaces or harsh environments.

The common fiber optic patch cord may wear out after being used for a long time, which affects the transmission quality. The repetition rate of armored fiber optic patch cords is much higher than that of ordinary fiber optic patch cords, up to about 75% (this data varies according to the complexity of specific wiring), and most of the ordinary fiber optic patch cords can not be recycled, and the recycling rate is less than 20%. High durability and repeatability can reduce wiring costs and reduce resource waste.

When the fiber optic patch cord is made into a branch, because the fiber optic patch cord is often pulled when used, the cable is easy to be pulled off, and the tensile ability is poor. Armored fiber optic patch cords can still be made into a variety of specifications of branch fiber optic patch cords, and the branch of the cable is still protected by stainless steel casing, greatly increasing the tensile performance.

Armored fiber optic patch cord has an important application in telecom fiber long-distance line, primary and secondary trunk line transmission, is the building wiring, key room equipment optical connection, field operation, sensing detection, optical fiber to the home, optical fiber to the desktop and other complex environment conditions under the use of optical transmission products of choice.
