What are the types of lightweight armored optical cables

Fiber and communications infrastructure knowledge brief Published 04 May 2025

Prepared for preliminary research by the ENSAA knowledge desk. Confirm optical interfaces, port or core capacity, electrical input and output, enclosure protection, thermal design and installation limits against current standards and product documentation.

Lightweight armored optical cables are designed to protect fibers while remaining flexible and easy to install, with common types including interlock, spiral, corrugated steel tape, and steel wire armored cables.

Overview

Lightweight armored optical cables combine mechanical protection with reduced weight, making them suitable for indoor, outdoor, and industrial applications where handling and installation efficiency are important. They typically feature a fiber core, strength members (aramid yarn or FRP rods), and a protective armor layer, all enclosed in an outer jacket made of PE, PVC, LSZH, or TPU depending on environmental requirements. Main Types1.

Interlock Armored Cable

Constructed with interlocking metal strips wrapped helically around the cable. Provides flexibility, crush resistance, and tensile strength. Suitable for indoor/outdoor transitions and areas with moderate mechanical stress.

2.

Spiral Steel Armored Cable

Features a helically wound steel strip around the fiber core. Offers excellent flexibility and ease of installation. Protects against rodent bites, UV radiation, and mechanical stress, ideal for outdoor applications.

3. Corrugated Steel Tape Armor (STA)Uses longitudinally folded steel tape wrapped around the cable. Provides high crush resistance and rodent protection.

Commonly used in direct burial or underground installations where maximum mechanical protection is required. 4. Steel Wire Armored Cable (SWA)Composed of multiple steel wires wound helically around the cable.

Offers superior tensile strength and impact resistance. Often deployed in underground or high-stress industrial environments. 5.

Square-

Lock Armored Cable

Uses square-profiled metal strips tightly wound around the cable. Provides good bending resistance and abrasion protection. Suitable for applications requiring frequent cable movement.

Key Features of Lightweight Armored Cables

Mechanical Protection: Shields fibers from crushing, bending, and rodent damage. Flexibility: Easier to handle and install compared to traditional heavy armored cables. Durability: Outer jackets and armor layers provide long-term protection in harsh environments.

Application Versatility: Can be used indoors, outdoors, in ducts, or for direct burial depending on the armor type and jacket material. Lightweight armored optical cables are ideal for scenarios where mechanical protection is needed without the bulk of traditional armored cables, balancing durability, flexibility, and ease of installation.
