In the National Electrical Code (NEC), fiber optic cables are categorized into various fire ratings, including OFNP/OFCP, OFNR/OFCR, OFNG/OFCG, and OFN/OFC. OFNP/OFCP is the highest flame-retardant rating in the NEC standards, meaning it is plenum-grade. ETK Kablo 's fire-resistant fiber optic cables ensure continuous data transmission during fire conditions, safeguarding critical communication lines when reliability is most crucial. The cable has a design that ensures operation for more than 3 hours in fires up to 1,000 degrees celsius Lifeline® MC Cable. "OF" refers to optical fiber, "N" means non-conductive, "C" means conductive, while"P", "R", and "G" stand for Plenum, Riser, and.
