Gydtza optical cable tensile strength

The GYDTZA optical fiber cable has short-term tensile strength up to 2200 N and long-term tensile strength up to 600 N, depending on fiber count and ribbon configuration.Tensile Strength OverviewGYDTZA cables are designed with a metallic central strength member and flame-retardant LSZH outer sheath, providing high mechanical durability and corrosion resistance . The allowable tensile load varies by fiber count and ribbon type:4-Fiber Ribbon: Short-term 1500 N, Long-term 600 N6-Fiber Ribbon: Short-term 1500–2200 N, Long-term 600 N8-Fiber Ribbon: Short-term 1500–2200 N, Long-term 600 N12-Fiber Ribbon: Short-term 2200 N, Long-term 600 N These values indicate the maximum tensile force the cable can withstand during installation (short-term) and during long-term service without compromising optical performance .Additional Mechanical PropertiesCrush Resistance: Short-term 1000 N/100mm, Long-term 300 N/100mmOperating Temperature: -40°C to 70°CWater-blocking Construction: Prevents moisture penetration and protects fibersHigh Fiber Density: Supports 4, 6, 8, or 12-fiber ribbons, with customized structures available Practical ImplicationsThe high tensile strength ensures that GYDTZA cables can be safely installed in aerial, duct, or indoor environments without fiber breakage. The combination of metallic strength members and LSZH sheath provides both mechanical protection and flame retardancy, making it suitable for FTTx, interoffice, and CATV networks . In summary, GYDTZA optical cables offer robust tensile performance, with short-term loads up to 2200 N and long-term loads up to 600 N, ensuring reliable operation under mechanical stress and environmental conditions.
