Aerial Self Supported 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.
What is ASU Cable
ASU optical 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.

The price of ASU fiber optic cable can vary depending on factors such as the fiber count, cable design, and the quantity ordered. Generally, ASU cables are competitively priced within the fiber optic market, especially considering their specialized all-dielectric design for aerial installation. For precise pricing, it’s best to contact the ASU cable manufacturer directly for a quote based on your specific requirements.
For custom ASU cables, we support customization of all parameters including the number of fibers, jacket material, color, diameter, logo, and packaging options to meet your specific needs.
ADSS and ASU optical cables differ primarily in their design for environmental and mechanical stress. ADSS cables are built to handle high electrical fields and longer spans, suitable for proximity to high-voltage power lines with robust aramid fiber reinforcements for added strength. In contrast, ASU cables are geared towards less electrically intense environments and shorter spans, making them ideal for urban or rural settings with easier installation and lower mechanical requirements. The choice between the two depends on the specific needs related to electrical exposure, span length, and installation complexity.
Since we are an ASU cable manufacturer, our minimum order quantity is set at 2 kilometers. This allows you to assess the quality effectively and facilitates easier transportation. We can arrange for courier delivery for this order size.
