Fiber optic lights are made with special high-molecular compounds as the core material and high-strength transparent flame-retardant engineering plastics as the outer sheath, ensuring no issues such as breakage or deformation for a considerable period, with a lifespan of at least 10 years. The use of high-purity core material effectively reduces attenuation during light transmission, achieving efficient light conveyance. It features high purity, low attenuation, and easy installation.
