ZTT 2-24J ADSS fiber optic cables are dielectric cables with a single-tube structure intended for overhead installations on spans up to 80 meters. They are reinforced with aramid fibers and two FRP (Fiber Reinforced Polymer) rods with a diameter of 0.58 mm embedded in the outer layer. Single-mode G.652D fibers were used, characterized by a reduced "water peak" (Zero Water Peak). The fibers are located in a central tube filled with a hydrophobic gel that protects them against moisture and vibration. The outer coating is made of high-density HDPE polyethylene (black), resistant to UV radiation and low and high temperatures (from -40[°C] to 70[°C]). The outer diameter of the cables is 5.2-6.2 mm and the maximum installation tension is 1-1.2kN. To make it easier to remove the outer coating, a double ripcord was used. Apart from overhead networks, ZTT 2-24j ADSS cables can be successfully used in telecommunications ducts.
