The utility model relates to the technical field of indoor miniature lead-in optical cables, and discloses a full-dry type indoor miniature lead-in optical cable, which comprises a loose tube, a water-blocking
yarn is arranged in the loose tube, and a tight tube
optical fiber is arranged in the water-blocking
yarn. According to the full-dry type indoor miniature lead-in optical cable, the steel strand and other parts are arranged, the
copper-plated steel strand is adopted, the mechanical tensile property of the optical cable is enhanced, additional
corrosion-resistant protection is provided, the
visibility and the identification degree of the optical cable are improved by utilizing the design that the outer sheath is extruded with the double-color strip, construction personnel can conveniently and rapidly identify the type of the optical cable, and the construction efficiency is improved. The water-blocking
yarn and the water-blocking tape are used for replacing traditional
factice filling to form a full-
dry structure, the problem of environmental
pollution possibly caused by
factice is avoided, the weight of the optical cable is reduced, the parallel reinforcers are combined with the steel tape for armoring, excellent anti-flattening performance and tensile strength are provided, and the problems that the mechanical tensile property is poor, and the service life is long are solved. And the construction personnel cannot quickly identify the type of the optical cable.
