A shift from metal to advanced engineering plastics (PC/ABS, GFRP composites) is transforming the fiber distribution box market. These new materials reduce enclosure weight by 30-50% while meeting IP65 protection standards and operating in temperatures from -40°C to 120°C. This trend is particularly impactful for outdoor waterproof, wall-mounted, and mini termination boxes, lowering installation and maintenance costs for global telecom operators and data center clients.
