- Product Introduction
SMC Fiber Optic Junction Box
Designed specifically for underground optical fiber splicing boxes and communication equipment deployment, it is made of sheet molding compound (SMC) composite material and complies with EN 124 D400 standards. It features high strength (compressive strength ≥200MPa), corrosion resistance (resistance to acids, alkalis, and chemical erosion), and lightweight (weighing only 10% of traditional concrete structures). Its modular assembly design can reduce transportation volume to one quarter of that of traditional prefabricated wells, significantly lowering logistics costs (increasing transportation efficiency by 75%), and enabling rapid deployment through pre-installed standardized interfaces (shortening the construction period by 40%).
This product adopts an integrated molding process to ensure IP68-level waterproof sealing performance and supports stable operation in extreme environments ranging from -40°C to 120°C. The flame retardancy (UL94 V-0) and UV resistance of SMC materials (in compliance with IEC 60068-2-5 standards) can extend the service life to 30 years and reduce the cost of later maintenance. The pre-drilled side panel design allows for on-site tool-free drilling, saving 50% of manual drilling time, and is compatible with various cable specifications (diameters 8-20mm).
By optimizing the supply chain management under the EPC model (reducing material costs by 18% through centralized procurement) and the construction process (reducing labor demands by 30% through mechanized installation), the overall project cost is reduced by 25% to 35% compared to the traditional solution.
