Abstract

The invention relates to the technical field of optical cables, in particular to a layer-stranded optical cable with a two-layer loose sleeve, which is characterized by at least comprising a central stiffener (5), an inner layer loose sleeve stranded around the central stiffener (5), an outer layer loose sleeve (1) positioned outside the inner layer loose sleeve and stranded around the inner layer loose sleeve, a protective layer (6) positioned outside the outer layer loose sleeve, and an outer protective layer (7) positioned outside the protective layer (6); and the interiors of each inner layer loose sleeve and each outer layer loose sleeve (1) comprise at least one light-guide fiber (3) respectively. The layer-stranded optical cable solves the problem that the optical cables with large core number are produced in a layer-stranded mode, and the diameters of the produced optical cables with the same core number are smaller than the diameters of optical fiber ribbon cables of corresponding specifications; therefore, the materials and cost are saved. Therefore, the layer-stranded optical cable greatly improves the capacity of the optical fibers in the layer-stranded optical cable, does not need to increase expensive production equipment, and saves the cost for manufacturers and operators.
