摘要: A limited combustible optical fiber includes a plurality of optical fibers in a loose tube or tight buffer arrangement. For example, a buffer tube jacket is made of a flame retardant material. A strengthening member made of aromatic polyamide fiber surrounds the buffer tube jacket. An outer layer jacket surrounds the strengthening member, wherein the buffer tube jacket and the outer layer jacket are formed by a composition including a fluoropolymeric base polymer and a nanoclay additive, such that the limited combustible fiber passes NFPA 255/NFPA 259 testing requirements.
