OFNG designates optical fiber nonconductive general-purpose cable, an all-dielectric fiber optic cable rated for general-use installation areas within a building.
OFNG designates optical fiber nonconductive general-purpose cable, a type within the family of nonconductive optical fiber classifications. The nonconductive designation indicates the cable contains no metallic elements, while the general-purpose rating indicates suitability for general installation areas, as distinct from the more demanding riser and plenum locations that require higher-rated cable.
Optical fiber cable classes are organized so that each is matched to the conditions of its installation. The OFNG rating reflects the cable's fire performance and intended general-use application, helping ensure that the correct optical cable type is applied in the appropriate setting within a structure.
In commercial and industrial facilities, optical fiber nonconductive general-purpose cable supports fiber communication in general installation areas with an all-dielectric construction. Selecting the correct class for both the nonconductive type and the location is part of building a compliant, dependable fiber system.
Because cable class is matched to the conditions of its location, recognizing the OFNG designation helps in applying the right all-dielectric product, reserving the higher-rated riser and plenum types for the demanding locations that require their elevated fire performance.
At Windy City Wire, the focus on fiber optic cable for commercial communication includes classes like OFNG. Supplying cable carrying the appropriate designations helps commercial facilities apply the right optical product for each part of their communication infrastructure.
