ASU Fiber Optic Cable
- ASU optical cable, or All-Dielectric Self-Supporting Utility cable, is designed for aerial installations where no additional support or messenger wires are needed.
- It’s entirely non-metallic, which makes it immune to electromagnetic interference, ideal for environments close to electrical power lines.
- The cable’s robust construction allows it to span between structures without sagging, making it a practical choice for telecommunications networks that require reliable, long-distance data transmission across varied terrains.
Aerial Self Supported ASU Fiber Optic Cable
ASU fiber optic cable is designed with high-quality materials that enhance its durability and performance in outdoor environments. The core is typically composed of multiple optical fibers, each housed within a protective buffer tube that’s filled with a gel to block water ingress. These elements are surrounded by a tough outer jacket made from materials like polyethylene (PE), which provides resistance to UV light, chemicals, and physical abrasions.
The ASU cable is characterized by its all-dielectric structure, which means it does not contain any metallic components, making it immune to electromagnetic interference and ideal for installations near power lines or areas prone to lightning. Its construction allows for excellent tensile strength and reduced sagging over longer spans without the need for a supporting messenger wire. This feature simplifies installation and reduces overall system cost.
ASU cables are specifically designed for aerial installation across poles in both urban and rural settings. Their lightweight and high strength make them suitable for spans across streets and between buildings without disrupting the environment. Additionally, the lack of metal components makes ASU cables a preferred choice in areas with high electromagnetic interference, such as near industrial facilities or power lines. They are commonly used in telecommunications for voice, data, and video transmission, providing a reliable medium for expansive network infrastructures.
Applications of ASU Cables
ASU Aerial Fiber Cable
ASU cable is ideal for overhead lines due to its non-metallic composition and robust resistance to environmental factors.
ASU Outdoor Fiber Cable
ASU cable thrives outdoors, offering high durability and full resistance to UV and harsh weather conditions.
Long Span Fiber Cable
ASU cable’s strong, lightweight design supports large spans without sagging, ideal for expansive aerial installations

Benefits of ASU Cable
Electromagnetic Interference Immunity
ASU cables, being all-dielectric, do not conduct electricity, making them ideal near power lines and in lightning-prone areas.
Self-Supporting Design
With no need for additional support structures, ASU cables simplify installation, reducing time and infrastructure costs.
High Environmental Resistance
The robust outer sheath protects against UV rays, chemical corrosion, and physical abrasions, enhancing longevity in outdoor installations.
