The invention discloses a low-smoke halogen-free self-supporting butterfly-shaped leading-in optical cable with nonmetal reinforcing parts, which comprises optical fiber ribbons, reinforcing parts and a sheath, wherein the number of the reinforcing parts is two . The invention discloses a low-smoke halogen-free self-supporting butterfly-shaped leading-in optical cable with nonmetal reinforcing parts, which comprises optical fiber ribbons, reinforcing parts and a sheath, wherein the number of the reinforcing parts is two . The butterfly optical cable is the novel user access optical cable which combines the characteristies of the indoor soft optical cable and the self-supporting optical cable together, it is the best altemative choice for solving the problems of FTTX network and plays the unique role in building. GJYXFHS optical cable is engineered for efficient conduit entry of optical cables, offering robust performance and durability. Note: The above relevant descriptions and technical parameters are for. For conduit entry of optical cables, the butterfly introduction places the communication unit at the center, with two parallel non-metallic strength members (FRP) placed on both sides. Additionally, an outer steel wire strength member is attached, and finally, it is.
