It is specially designed for butterfly optical cable overhead wiring scenarios and is used to bind the suspension wire of self-supporting butterfly optical cables. By cooperating with supporting devices such as ring hooks and tight hoop hooks, the optical cables are pulled. FTTH Butterfly Optic Cables were designed to eliminate those compromises. The name comes from the cross-section: a flat, wing-shaped profile with the optical fiber sitting in the center and two parallel strength members flanking it on either side. It is suitable. The invention belongs to the technical field of optical cables, and discloses a butterfly-shaped drop-in optical cable for communication, which has a fitting part (1), a plurality of protection bodies (2), a plurality of butterfly-shaped drop-in units (3), a protective layer (4), The outer sheath. Although it is said that outdoor single-mode butterfly fiber optic cable is widely used for long-distance transmission in integrated wiring, not many people have a deep understanding of its purchase.
