The FTTH Drop Fiber Cable is also called butterfly optical cable because it looks like a butterfly in cross section. It has the advantages of small outer diameter, light weight, low cost, reliable performance, and easy installation. They are called butterfly-shaped due to their unique design, which features a flat shape with two parallel fiber ribbons running down the center. An ordinary drop cable utilizes a standard figure-eight structure, with two parallel strengthening cores and an optical fiber in the middle. A self-supporting drop cable, on the other hand, adds a thick steel wire suspension to the ordinary drop cable structure. Essentially, the self-supporting. Indoor FTTH drop cable (GJXFH, GJXH, GJXKH) adopt a butterfly-shaped flat structure, with the optical fiber unit in the center of the optical cable, two parallel reinforcements (metal steel wire, non-metallic FRP or KFRP) placed on both sides, and finally extruded with low smoke and no smoke. FTTH drop cable is widely used in the access network due to its softness and lightness; because its shape is butterfly-shaped; it is also called butterfly cable, 8 digit optical cable, and FTTH drop cable is usually 1core,2core or 4core.
