ZTT DZ-XOTKtcdD is a fiber optic cable designed for direct burial in the ground (DAC). It is equipped with 2 G.657.A1 (Singlemode) fibers placed in a single central tube. The maximum tensile strength is 1.2 kN, and the cable features reinforcement in the form of two FRP rods and glass fibers. The DZ-XOTKtcdD has an orange polyethylene (PE) sheath with a thickness of 1.2 mm. The outer diameter of the cable is approximately 5.3 mm. The offered product is intended for direct burial in the ground without the need for additional protective conduits and stands out for its very high crush resistance of 4 kN.
Cable Construction
The cable features a single, centrally located tube containing two optical fibers. The product is reinforced with two FRP rods, and the entire structure is additionally strengthened circumferentially with glass fiber. The cable stands out for its very high crush resistance—up to 4 kN—which ensures durability against pressure that may occur during direct burial installation in the ground.
Direct Burial Installation
The offered product is designed for direct burial in the ground without the use of additional protective conduits. Using this type of cable significantly simplifies the installation process and reduces costs. The cable is characterized by very high crush resistance (4 kN), which is essential for direct underground installation. The cable can also be successfully used in telecommunication ducts.
The sheath is made of PE (polyethylene). The fiber optic cable is suitable for outdoor installation, and its CPR classification is Fca.
2 G.657.A1 (Singlemode) Fibers
The fiber optic cable contains 2 G.657.A1 (Singlemode) optical fibers. These fibers offer better flexibility compared to G.652.D, at the cost of slightly higher attenuation. They are perfectly suited for connecting subscribers in locations where the cable is installed underground rather than overhead.
