1 The intent of this Standard is to evaluate the integrity of power, control, instrumentation, and data/communications cables (such as copper, coaxial, or optical fiber) for their ability to maintain circuit integrity when subjected to standard fire test exposure and. Long before optical performance enters the picture, the fiber optic cable jacket fire rating decides whether a cable is legal - and safe - to run through a plenum ceiling, a riser shaft, an office pathway, or an outdoor route. 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). Purchasers, specifiers, installers and inspectors of cables placed in risers or plenums during building construction or upgrade know cables that do not meet safety requirements present a significant risk of hastening the spread of fire. Understanding the fire ratings and jacket options for fiber optic cables is crucial for ensuring optimal performance and safety.
