ADSS (All-Dielectric Self-Supporting) optical cable is a type of fiber optic cable that is designed to be self-supporting and to eliminate the need for a metallic support structure. ADSS optical cable is commonly used in overhead installations such as power lines, and it has become popular due to its lightweight and high-tension capabilities. In this article, we will discuss the structure and characteristics of ADSS optical cable.
Structure of ADSS Optical Cable
ADSS optical cable consists of several layers of materials that provide protection to the optical fibers and support the cable weight. The basic structure of ADSS optical cable includes the following layers:
Fiber Optic Core: This is the central part of the cable, where the optical fibers are located. The core is made up of a high-strength, low-weight material such as aramid yarns or fiberglass.
Buffer Coating: The buffer coating is a layer of material that surrounds the optical fibers and protects them from external mechanical stress. The buffer coating can be made up of a variety of materials, including acrylate, silicone, or polyimide.
Central Tube: The central tube is a rigid tube that houses the fiber optic core. It is typically made of a high-strength, low-weight material such as fiberglass or aramid yarns.
Water-Blocking Material: A water-blocking material is applied around the central tube to prevent water from entering the cable. This layer can be made up of various materials such as polyethylene, polypropylene, or gel.
Protective Layer: The protective layer is a layer of material that provides mechanical protection to the cable. It is typically made up of aramid yarns or fiberglass.
Outer Sheath: The outer sheath is the final layer of the cable and provides additional protection against external mechanical stress. It can be made up of various materials such as polyethylene or polyvinyl chloride.
Characteristics of ADSS Optical Cable
High Tension Strength: ADSS optical cable is designed to support its own weight and withstand high tension forces without the need for a metallic support structure. The cable is typically designed to withstand a tension strength of up to 1,000 pounds or more.
Lightweight: ADSS optical cable is significantly lighter than traditional metallic cables, which makes it easier to install and handle.
No Electrical Conductivity: ADSS optical cable is made up of dielectric materials, which means it has no electrical conductivity. This makes it safer to install near electrical power lines, as it eliminates the risk of electrical interference.
Resistant to Corrosion: ADSS optical cable is resistant to corrosion and can withstand harsh environmental conditions such as high humidity, extreme temperatures, and exposure to chemicals.
High Bandwidth Capacity: ADSS optical cable has a high bandwidth capacity, which means it can transmit large amounts of data at high speeds over long distances.
Easy to Install: ADSS optical cable is easy to install, as it does not require a metallic support structure. This reduces installation time and costs.
In conclusion, ADSS optical cable is a high-performance fiber optic cable that is designed to be self-supporting and lightweight. It is commonly used in overhead installations such as power lines, and it provides high-tension strength, resistance to corrosion, and high bandwidth capacity. With its unique structure and characteristics, ADSS optical cable has become a popular choice for high-speed data transmission over long distances.
