Directly-buried armored bundled pipeline composite miniature optical cable

The utility model relates to a directly-buried armored bundled pipeline composite miniature optical cable. The bunched cable comprises a bunched cable outer sheath layer and a plurality of bunched cable micro-tubes, bunched cable optical units are arranged in the bunched cable micro-tubes, a bunched cable metal armor layer is arranged on the inner side wall of the bunched cable outer sheath layer,and the bunched cable metal armor layer is made of a stainless steel belt. The miniature optical cable provided by the utility model can be directly laid and used during line construction, avoids multiple times of wiring construction on site, can effectively shorten the engineering period and reduce the labor intensity, and can also avoid damage to the optical cable and influence on data transmission caused by penetration and placement of the optical cable on site; and the stainless steel band is arranged in the outer sheath of the bunched cable to be used as an armor layer of the bunched cable, so that the rigid str
