ADSS (All-Dielectric Self-Supporting) cable It is a type of fiber optic cable used in telecommunications networks, especially in aerial installations. This cable has become a popular choice due to its ability to support its own weight without the need for additional metal supports.. To ensure optimal performance and network durability, It is essential to understand the key parameters of ADSS fiber optic cable.
When selecting ADSS optical cable parameters, we need to choose the correct ADSS optical cable manufacturer. The following points need to be noted:
1: Optical fiber
Regular optical cable manufacturers generally use A-grade fiber cores from large manufacturers. Some low-priced and inferior optical cables usually use C-grade, D-grade optical fibers and smuggled optical fibers of unknown origin. These optical fibers have complex sources and have been out of the factory for a long time, and are often damp. Discoloration, and single-mode optical fiber is often mixed with multi-mode optical fiber. However, small factories generally lack the necessary testing equipment and cannot judge the quality of optical fiber. Because such optical fibers cannot be distinguished by the naked eye, common problems encountered during construction are: narrow bandwidth and short transmission distance; uneven thickness and inability to be connected to pigtails; lack of flexibility of optical fibers and breakage when coiled.
2. Reinforced steel wire
The steel wires of outdoor optical cables from regular manufacturers are phosphated and have a gray surface. Such steel wires will not increase hydrogen loss, will not rust, and have high strength after being cabled. Inferior optical cables are generally replaced with thin iron wires or aluminum wires. The identification method is easy because they appear white and can be bent at will when held in the hand. Optical cables produced with such steel wires have large hydrogen losses. Over time, the two ends where the fiber optic boxes are hung will rust and break.
3. Outer skin
The PE sheath of outdoor optical cables should be made of high-quality black polyethylene. After the cable is formed, the outer sheath should be smooth, bright, uniform in thickness, and free of small bubbles. The outer sheath of inferior optical cables is generally produced from recycled materials, which can save a lot of costs. The outer sheath of such optical cables is not smooth. Because there are many impurities in the raw materials, the outer sheath of the finished optical cable has many very small pits. Over time, it will crack and develop. water.
