Home / Parameters of Buried Flame-Retardant Optical Cables
Proceeding flame retardant and fire-resistant test, LOI of ceramic sheathing materials and temperature index of cable according to EN ISO 4589 are up respectively to 40% and 370°C. Corning Optical Communications manufactures quality flame retardant optical fiber cables for indoor applications, which comply with the requirements of the National Electric Code® (NEC® 2023) published by the National Fire Protection Agency (NFPA). The cable has a design that ensures operation for more than 3 hours in fi es up to 1000 °C. Its structure is mainly composed of cable core, longitudinal covering a layer of two-sided synthetic mica tape outside cable core, inner sheath packed with ceramic sheathing. They are mainly installed inside buildings, tunnels,subways or closed areas in general, specially designed to guarantee the signal transmission even in case of fire.
