Abstract
A fire resistant optical communication cable is provided. The fire-resistant optical communication cable includes an extruded cable body including an inner surface defining a passage in the cable body and an outer surface. The fire-resistant optical communication cable includes a plurality of elongate optical transmission elements located within the passage of the cable body. The fire-resistant optical communication cable includes a layer of intumescent particles embedded in the material of the cable body forming an intumescent layer within the cable body. The cable may include one or more elements having flame resistant coatings that, upon exposure to heat, form a ceramic layer increasing the combustion time of the coated element.
