In some of these applications, it is important for the cables to be flame resistant. This is because a fire can cause significant damage to a building and its occupants, and flame resistant cables can help to prevent the spread of fire.<\/p><p>The National Electrical Code (NEC) has established eight levels of fire resistance for fiber optic cables. These levels are based on the time it takes for a cable to burn through or melt. The higher the level, the longer the cable will take to burn.<\/p><p>The four levels of fire resistance for nonconductive fiber optic cables are:<\/p><ul><li>OFNP: Optical Fiber Non-conductive Plenum<\/li><li>OFNR: Optical Fiber Non-conductive Riser<\/li><li>OFNG: Optical Fiber Non-conductive General Purpose<\/li><li>OFCG: Optical Fiber Non-conductive General Purpose (limited use)<\/li><\/ul><p>The four levels of fire resistance for conductive fiber optic cables are:<\/p><ul><li>OFCP: Optical Fiber Conductive Plenum<\/li><li>OFCR: Optical Fiber Conductive Riser<\/li><li>OFN: Optical Fiber General Purpose<\/li><li>OFC: Optical Fiber Conductive General Purpose<\/li><\/ul><p>The higher the fire resistance level, the more resistant the cable is to heat and flame. OFNP is the highest fire resistance level, and OFC is the lowest.<\/p><p>\u00a0<\/p><p>In general, flame resistant fiber optic cables are used in plenum spaces, risers, and other areas where there is a risk of fire. Plenum spaces are areas where air flows and\/or is distributed throughout a building. Risers are vertical shafts or ducts that run through one or more floors.<\/p><p>\u00a0<\/p><p>When choosing a fiber optic cable for a particular application, it is important to consider the fire resistance requirements of the application. The NEC specifies the fire resistance requirements for fiber optic cables in different areas of a building.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-6aa3a2e elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"6aa3a2e\" data-element_type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-61a0013\" data-id=\"61a0013\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-5cbc12e elementor-widget elementor-widget-image\" data-id=\"5cbc12e\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t<img fetchpriority=\"high\" decoding=\"async\" width=\"950\" height=\"628\" src=\"https:\/\/www.sumecnavigator.com\/wp-content\/uploads\/2023\/07\/indoor-fiber3.png\" class=\"attachment-large size-large wp-image-13136\" alt=\"\" srcset=\"https:\/\/www.sumecnavigator.com\/wp-content\/uploads\/2023\/07\/indoor-fiber3.png 950w, https:\/\/www.sumecnavigator.com\/wp-content\/uploads\/2023\/07\/indoor-fiber3-300x198.png 300w, https:\/\/www.sumecnavigator.com\/wp-content\/uploads\/2023\/07\/indoor-fiber3-768x508.png 768w\" sizes=\"(max-width: 950px) 100vw, 950px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>Fiber optic cables are used in a wide variety of applications, including telecommunications, data networking, and security systems.
