Introduction
Fiber optic patch cables are an essential part of any network infrastructure. They are used to connect different optical equipment, such as switches, routers, and servers. However, in harsh environments or where cables are exposed to wear and tear due to different reasons, regular optical cables might not be adequate. Here comes the role of armored fiber optic patch cables, which offer a reliable and robust solution for such scenarios.
What is Armored Fiber Optic Patch Cable
An armored fiber optic patch cable is a type of fiber optic cable that has a metal protective layer around its outer sheath, providing extra strength and durability. This layer is usually made of stainless steel or aluminum, which are resistant to corrosion and physical damage. The armored layer protects the inner optical fibers from being damaged, bent, or broken due to external pressure or abrasion. Additionally, the armored shell provides extra protection against rodent damage and prevents the cable from being easily cut through.
Compared to regular fiber optic patch cables, armored fiber optic patch cables have several advantages. Firstly, they are highly resistant to crushing and kinking, making them ideal for use in harsh environments. Secondly, they are suitable for outdoor use where the cable may be exposed to various weather conditions. Thirdly, they have a longer lifespan than regular fiber optic patch cables, reducing the need for frequent replacements. Fourthly, they can withstand the harsh effects of chemicals and solvents making them reliable for use in industrial applications.
Internal Structure of Armored Patch Cable
The internal structure of an armored fiber optic patch cable consists of several layers, including the outer jacket, the protective sheath, the metal armor, and the optical fibers. The outer jacket is the first layer that covers the cable, and it is made of thermoplastic material, which provides flexibility and resistance to moisture. The protective sheath is the second layer, which is made of loose tubes, from which the fibers run. The metal armor layer covers the protective sheath and is used as a primary layer of mechanical protection. Finally, the optical fibers are at the center of the cable surrounded by all the other layers.
Why do We Need Armored Fiber Patch Cable?
Certain environments expose fiber optic cables to more danger than others. In industrial, military, and communication environments, for example, the cables may be exposed to high pressure, explosive substances, chemicals, or moisture. These hazards put the cables' integrity at risk, leading to unexpected downtimes or service degradation. Using armored fiber optic patch cables helps reduce the need for repair and replacement while ensuring the network's continuity, reducing associated repair costs.
Types of Armored Fiber Optic Patch Cable
Armored fiber optic patch cables can be classified based on multiple variables, including the applications and the type of armored layer. Classifying them based on the applications means categorizing them as either indoor or outdoor. An indoor armored fiber optic patch cable is designed for use in a protected environment, such as office buildings and data centers, where exposure to moisture or excessive heat is unlikely. On the other hand, outdoor armored fiber optic patch cables are designed to withstand exposure to moisture, UV rays, and temperature changes.
Another classification is based on the type of armored layer. The two types are loose-tube and tight-tube armored fiber optic patch cables. Loose-tube armored fiber optic patch cables have a high degree of flexibility, hence the name "loose." However, they are less resistant to kink and crushing. Tight-tube armored fiber optic patch cables, on the other hand, have a rigid structure that offers more protection against crushing and kinking.
Conclusion
Armored fiber optic patch cables provide reliable and robust connectivity solutions in harsh environments, becoming increasingly essential in modern networking infrastructures. With a protective layer of metal armor around the outer shell, armored fiber optic patch cables offer mechanical protection and durability, protecting the optical fibers from physical damage and environmental hazards. They stand out because of their longevity and reliability in conditions of wear and tear, and as such, they are a worthwhile investment for telecommunication infrastructure.
