| 摘要 |
The present invention relates to a loose tube, optical ribbon cable, which comprises a central tensile strength component (210) situated in the center of the optical ribbon cable; a plurality of loose tubes (260) mounted with a bundle of optical ribbon fibers (240), the bundle of optical ribbon fibers being formed by laminating multiple optical ribbon fibers, each optical ribbon fiber including multiple cores of optical fibers stranded in a single row and a sheath surrounding the multiple cores of optical fibers, wherein the plurality of loose tubes being stranded around the central tensile strength component; a plurality of circle-shaped water absorbing members (300) arranged in a hollow which is formed outside a pair of the loose tubes neighboring each other; a water absorbing tape (270) for surrounding the plurality of loose tubes and plurality of circle-shaped water absorbing members; and, an external sheath (290) situated outermost of the optical ribbon cable for protecting an interior of the loose tube optical ribbon cable against the external environment. <IMAGE>
