Abstract
An arrangement provides for an optical fiber cable having a plurality of fiber optic elements including a glass portion and a UV optical coating portion. A plurality of buffer tubes each contain one or more of the plurality of optical fibers made of a fire retardant polymer. A jacket surrounds the buffer tubes also made of a fire retardant polymer. The fire retardant polymers for the plurality of buffer tubes and for the jacket are selected from PVDF (PolyVinyliDene Fluoride) or FRPVC (Fire Resistance Poly Vinyl Chloride). The ratio of total polymer to UV optical coating of the fiber optic elements, by area, is substantially in the range of 5:1 to 9:1.
