Application Summary AI generated

GB/T 46331-2025 specifies the technical requirements, test methods, and inspection rules for optical fibre cables designed for direct surface installation without trenching or protective conduits. It is applied in telecommunications and utility networks where cables are laid on the ground surface, such as temporary communication links, rural broadband deployment, or emergency restoration scenarios. The standard ensures mechanical durability, environmental resistance, and optical performance under exposure to sunlight, moisture, and physical abrasion.
