Conventional fiber patch cords are prone to wear after a long period of use, which affects the transmission quality. Therefore, armored fiber optic patch cords are beginning to be used by more and more people. In this article, Bonelinks will deliver some basic but important introductions to armored fiber patch cords!

What is Armored Fiber Patch Cord?

Armored fiber patch cord is a kind of optical fiber jumper designed with a layer of stainless steel sleeve to protect the optical fiber. It has the advantages and functions of a standard optical fiber patch cord, but at the same time has the durability of armor. Armored optical fiber patch cord has the characteristics of high tensile, high compressive, high bending, fire-proof, moisture-proof and anti-rodent resistance, and is mainly used in residential areas, outdoor places and computer room buildings, etc.

Armored Fiber Patch Cord Structure

  • The micro-caliber stainless steel hose is the protective layer closest to the optical fiber, which can prevent damage caused by mechanical force.
  • The fiber optic patch cord contains Kevlar fiber, which has permanent heat resistance and flame retardancy, permanent antistatic properties, acid and alkali resistance, high strength and high wear resistance.
  • High-strength PVC is used as the surface material, which can be flame-retardant, chemical-resistant, and tear-resistant, and it also increases the softness and elasticity of the armored optical fiber patch cord.

What Sets Armored Fiber Patch Cord Apart from Ordinary Fiber Cord?

Non-Armored Fiber Patch Cord vs Armored Fiber Patch Cord

AspectOrdinary Patch Cord (Non-Armored)Armored Patch Cord
Stress ResistanceBasic stress resistanceEnhanced stress resistance due to micro-diameter stainless steel sleeve
FlexibilityStandardMaintains flexibility similar to standard fiber optic patch cord
Protective LayerNoneMicro-diameter stainless steel sleeve acts as a protective layer closest to the optical fiber
Bending PerformanceStandardGood bending performance and flexibility with small external warp and light weight
Additional Surface Material (Some)NoneHigh strength PVC as surface material for flame retardant, chemical corrosion resistance, tear resistance, increased flexibility and elasticity

Armored Fiber Patch Cord Type

By Metal Tube

Armored fiber optic patch cords can be divided into interlocking armor and corrugated armor according to the metal tubes.

Interlocking armor is a kind of aluminum armor, which is spirally wound on the fiber optic patch cord. It is used in indoor and outdoor optical cables. It is durable and resistant to strong pressure and other characteristics.

The corrugated armored optical fiber patch cord is made of longitudinal folds wrapped by steel tape. It is typically applied outdoors to protect against damage from machinery and rodents.

By Application Environment

The armored fiber patch cord is designed to match various application environments, leading to its division into two types: outdoor and indoor Armored Fiber Optic Cables. These categories address specific protection needs and usage scenarios:

Indoor Armored Fiber Patch Cord: Crafted to guard against threats like rodent interference and physical damage, the indoor version features crush-resistant aramid yarns. A sturdy steel tube adds an extra layer of defense, protecting against cutting and abrasion. This type is ideal for spaces like data centers and high-density cabling, where data integrity is vital.

Outdoor Armored Fiber Optic Cable: Tailored for outdoor challenges, this cable excels in direct burial or aerial applications. With a crush-resistant corrugated steel tube and aluminum interlocking armor shielding against rodents and abrasion, it’s the go-to choice for demanding environments. Whether spanning campus backbones or connecting buildings, this cable ensures reliable communication over long distances.

Why Use Armored Fiber Patch Cord?

Conventional optical fiber patch cords are vulnerable to damage from animals, environmental wear, weather, and acidic substances during use. They are relatively fragile, and the maintenance and management costs in the later period are relatively high. The armored fiber optic patch cord not only retains all the advantages of the standard fiber optic patch cord, but also adopts a structural design for harsh environments. It is highly adaptable, highly resistant to pressure, and low cost, so it is favored.

The Benefits of Armored Fiber Patch Cord

  • High Tensile Strength: Armored fiber optic patch cords are known for their robust tensile strength, ensuring resistance against strain and tension.
  • Stress Resistance: These patch cords exhibit exceptional resistance to stress, making them suitable for challenging environments.
  • Rat Bite Resistance: The design of armored patch cords prevents damage from rodent bites, enhancing durability.
  • Crush Resistance: Their construction makes them resistant to crushing and damage, contributing to longevity.
  • Harsh Environment Use: Armored patch cords can be laid directly outdoors and in harsh conditions without the need for additional protective measures.
  • Flexible Bending: Despite their strength, armored patch cords offer flexible bending capabilities, allowing them to bend without breaking.
  • Space Saving: The bending and diameter of the cable are not heavily restricted, which saves space and simplifies construction layouts, ultimately reducing costs.
  • Terminal Interface Variety: They can be equipped with various terminal interfaces like SC, ST, FC, LC, and MU.
  • Stainless Steel Protection: A stainless steel sleeve protects the patch cord from external pressure and rodent penetration.

Where Can Armored Fiber Patch Cord be Used?

Armored patch cords are suitable for complex environments such as building wiring, optical connection of equipment in key computer rooms, field operations, sensor detection, fiber-optic entry, and community backbone network wiring. The stainless steel sheath tube can protect the fiber optic patch cords from being squeezed and prevent rodents from penetrating.

Another application of armored fiber optic patch cords is in data centers, which can provide flexible interconnection for active equipment, passive optical equipment, and cross-connects. Conventional fiber optic patch cords are vulnerable to damage from animals, natural wear, weather, and chemical corrosion during use. They are not only fragile, but also costly in later maintenance and management.
