Outdoor and Aerial Fiber Optic Cable: Conquering the Elements
For many telecommunications projects the most efficient way to deploy fiber is to go above ground. Aerial fiber optic cable installation utilizes existing utility poles and infrastructure providing a cost effective alternative to underground trenching. However aerial cables are exposed to the most severe environmental stresses including high winds ice loading UV radiation and extreme temperature cycles. To meet these challenges we manufacture a specialized range of Outdoor Fiber Optic Cable and Self Supporting (ADSS) cables. These products are engineered with high strength members and weather resistant jackets to ensure they remain stable and functional for decades regardless of the weather.
The primary engineering challenge for aerial fiber is managing the tension and sag of the cable over long spans. Our All Dielectric Self Supporting (ADSS) cables are designed to be strong enough to support their own weight and the additional weight of ice without the need for a separate messenger wire. We utilize high strength aramid yarns as the central strength member which provides the necessary tensile strength while keeping the cable lightweight and non conductive. This dielectric construction is a major safety advantage as the cable can be installed near high voltage power lines without the risk of electrical arcing or grounding issues.
UV protection and moisture resistance are also critical for outdoor fiber. Standard plastic jackets can be quickly degraded by the sun's ultraviolet rays leading to cracks and moisture ingress. Our outdoor cables feature high density polyethylene (HDPE) jackets that are enriched with carbon black for maximum UV resistance. We also utilize water swellable yarns and tapes that act as a dry barrier against moisture. Unlike traditional gel filled cables our dry core designs are easier to work with and lighter in weight simplifying the installation process for aerial crews. This focus on material quality ensures that the cable maintains its physical and optical properties even after years of exposure to the elements.
Thermal stability is another area where our outdoor fiber products excel. As the temperature changes the materials in a cable expand and contract at different rates. If not properly managed this can cause micro bends in the glass fiber leading to increased signal loss. Our cables are designed with a loose tube structure where the fibers sit freely inside a protective tube filled with a soft gel or yarn. This allows the cable to expand and contract without putting stress on the fibers themselves ensuring consistent performance from the heat of the summer to the deepest freeze of winter. Our outdoor cables are tested to perform reliably in temperatures ranging from minus forty to plus seventy degrees Celsius.
In conclusion outdoor and aerial fiber optic cable is a vital component of the global communication network. Its ability to conquer the elements and provide high speed connectivity over long distances is essential for bridging the gap between cities and rural areas. As a manufacturer we are committed to providing the most durable and reliable outdoor fiber solutions on the market. Whether you are building an aerial network along a highway or a direct buried link across a mountain range our products are engineered to stand up to the toughest conditions.
