Abstract
The invention discloses an environment-friendly optical cable which comprises an optical cable frame, optical fiber units, an inner sheath, a glass fiber wrapping layer and an outer sheath. A plurality of recessed troughs for placing the optical fiber units are arranged outside the optical fiber frame. The inner sheath packages the optical cable frame. The glass fiber wrapping layer is arranged between the inner sheath and the outer sheath. A flame-retardant heat-resistant layer is arranged between the glass fiber wrapping layer and the outer sheath. The environment-friendly optical fiber has beneficial effects of sufficiently protecting the optical fiber units from extrusion through utilizing the optical cable frame for arranging the optical fiber units in the optical cable, realizing a certain inclination angle, effectively ensuring transmission efficiency of the optical cable, improving operation efficiency and furthermore effectively realizing environment-friendly performance.
Description
Technical field
The present invention relates to a kind of optical cable, particularly relate to a kind of environment-friendly optical cable.
Background technology
Along with the development of society; environmental protection is more and more by people are paid attention to; for improving the environmental-protecting performance of optical cable; generally can add some inorganic anti-flaming materials manufacturing in optical cable insulating and sheath macromolecular material used; but adding of these inserts is limited; add electrical property and mechanical property that these fillings can reduce optical cable, if add too many, the electrical property of optical cable and mechanical property just cannot meet request for utilization.
Therefore, for solving the problem, spy provides a kind of new technical scheme.
Summary of the invention
The invention provides a kind of environment-friendly optical cable.
The technical solution used in the present invention is:
