The butterfly-shaped optical cable is made by placing the optical communication unit in the center, placing two parallel reinforcing elements on both sides, and finally extruding a layer of sheath. It has excellent mechanical properties, simple cable structure, light weight and. The invention belongs to the technical field of optical fiber and cable, and in particular relates to a butterfly-shaped lead-in optical cable, which includes an optical fiber, a pair of strength members symmetrically distributed on the upper and lower sides of the optical fiber, and a sheath that. Their flat, butterfly-shaped structure combines optical fibers with strength members, making them ideal for indoor wiring, drop cable installations, and last-mile network construction. It offers an efficient and economical solution for deploying fiber in FTTH network. Central loose tube cables and self-supporting FTTH drop cables are desinged for outdoor aerial distribution. A self-supporting drop cable, on the other hand, adds a thick steel wire suspension to the ordinary drop cable structure.
