In the world of fiber optic communication, ADSS (All-Dielectric Self-Supporting) fiber optic cables play a significant role. They are designed with specific features and are accompanied by various accessories to ensure optimal performance in different installation scenarios. Weunion article will delve into the details of ADSS fiber optic cables and their corresponding accessories, as well as the crucial aspect of proper matching selection.
Single Sheath ADSS Cable
Single sheath ADSS cable are typically used in environments where the span between support structures is no greater than 150 meters. They are well-suited for relatively shorter distances and can effectively meet the transmission requirements within such spans. Their design allows for reliable signal transmission while being cost-effective for these specific installation situations.
Double Sheath ADSS Cable
Double sheath ADSS cable are engineered for more challenging installation environments. When the span between support towers exceeds 200 meters and there is a relatively high requirement for tensile strength, these cables come into play. They can withstand greater forces exerted on them, ensuring that the fiber optic transmission remains stable and reliable even under significant mechanical stress. Moreover, they are capable of being installed over long distances, with the cables being designed to be strong enough to allow lengths of up to 700 metres to be installed between support towers.
Mini ADSS-ASU Cable
The Mini ADSS-ASU cable are designed with particular limitations and advantages. They are ideal for use when the span is within 100 meters and the number of cores is 48 or less. Their compact size and specific capabilities make them a preferred choice for shorter and less demanding fiber optic connections in certain areas, such as in local network expansions or for connecting specific facilities within a relatively small geographical range.
The construction of ADSS fiber optic cable involves several meticulous steps. The fibers are carefully positioned in a loose tube made of high modulus plastic. This loose tube provides a certain degree of flexibility and protection to the fibers. The tube is then filled with gel, which serves to further safeguard the fibers from moisture and mechanical stress. Tubes (and fillers) are stranded around the non-metallic strength member to form the fiber cable core. This core is a crucial part of the fiber cable’s structure, providing the necessary strength and support.
After the formation of the fiber cable core, it is filled with a water-blocking compound. This compound prevents water from infiltrating the fiber cable and reaching the fibers. Subsequently, a PE (Polyethylene) inner jacket is extruded around the core. The inner jacket provides an additional layer of protection and helps in maintaining the structural integrity of the core.
To further reinforce the fiber cable, aramid yarn is twisted around the inner jacket. Aramid yarn is known for its high strength and durability, enhancing the fiber cable’s ability to withstand tensile forces. Finally, depending on the specific requirements and application scenarios, either a PE outer jacket or an AT (Aramid Tube) outer jacket is completed. The outer jacket is the outermost layer that directly interacts with the external environment, protecting the fiber cable from various elements such as sunlight, moisture, and physical abrasion.

Wedge Clamp
Wedge clamps, like PA1500 and PA2000, are vital for ADSS fiber cable installation. They fasten the fiber cable to support structures, grip it firmly, and distribute the load evenly, keeping the fiber cable in place in bad weather or under stress. The right clamp model depends on fiber cable diameter, span length, and expected load.
Guy Grip
The guy grip is vital for ADSS fiber cable installation, maintaining tension and suspension. It’s made of durable materials to bear forces. There are different types for various fiber cable diameters and spans.
Proper installation is key to avoid cable damage. Climate affects its selection; in harsh conditions, stronger ones are needed.
It should be compatible with other accessories. Match it with ADSS fiber cable considering fiber cable features and installation conditions for reliable network operation.
UPB Pole Band
The UPB Pole Band is used with ADSS fiber cable installations to attach the fiber cable to poles or other support structures. It offers a reliable, adjustable way to secure the fiber cable, allowing flexibility in installation and proper positioning. It can be adjusted based on pole diameter and requirements for a stable connection.
Matching Selection of ADSS fiber Cable and Accessories
Properly matching ADSS fiber cable with accessories is very important for installation. For example, for single sheath ADSS fiber cable with a 150-meter span, PA1500 wedge clamp might be suitable depending on cable diameter and local conditions. For longer spans with double sheath fiber cable, stronger suspension tension clamp and suitable pole bands are needed for stability.
The choice of accessories also considers factors like the installation environment , and the cable’s fiber number and future network expansion. In extreme conditions, more durable accessories should be chosen.
In conclusion, when it comes to the installation and operation of a successful fiber optic network, understanding ADSS cable, their features, accessories, and making the proper matching selection is crucial.
