The utility model relates to a double rubber -insulated -wire cable belongs to optical cable technical field, including two optic fibre, two support piece, an optic fibre and a support piece be a set of, have a sheath with a set of optic fibre and support piece cladding outward, and adjacent sheath between two sets of links together through the linkage segment side by side, and the support piece of every group lies in the one side of keeping away from the linkage segment. Double rubber -insulated -wire cable reasonable in design, simple structure, two cores can use simultaneously, perhaps only use an optic fibre, another reservation, have avoided the waste of rubber -sheathed lamp cord, have reduced the cost in the construction, and simultaneously at the welded in -process, it is more convenient that the operation is got up, can effectual solution butt fusion in -process pad value too big defect, can effectively improve the work efficiency of butt fusion in -process and the stability of quality, practiced thrift the cost in the work progress, avoided the destructiveness to optic fibre.
