    摘要: Disclosed is a dry single tube fiber optic cable of the loose tube variety in which there is no filling or flooding materials but none the less adequate provisions are made to protect the optical fibers from damage due to water penetration. The cable structure comprises (1) one or more groups of optical fibers each held together by a circumscribing water absorbent material; (2) a buffering tube having an internal channel larger than the one or more groups of optical fibers in which the groups of optical fibers are moveably disposed; (3) a strength member circumscribing the buffering tube; (4) a water absorbent material circumscribing the strength member, and (5) a jacket circumscribing the strength member.
