Features LSZH coating to prevent flame spread and the release of toxic gases after ignition. Capability of production with PVC and polyethylene PE coatings. No water leakage. 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. This geometry gives the cable its distinctive look. 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. 1 Traditional butterfly-type optical cable product description : GJYXCH (Metal Reinforcement, LSZH Sheath, Self-supporting) GJYXDCH (fiber optic tape, metal reinforcement, LSZH sheath, self-supporting) GJYXFCH (Non-metallic Reinforcement, LSZH Sheath, Self-supporting) GJYXFDCH (Fiber Optic Tape. Butterfly-shaped optical fiber cables are a popular type of fiber optic cable that is commonly used for data transmission in telecommunication networks. They are called butterfly-shaped due to their unique design, which features a flat shape with two parallel fiber ribbons running down the center. The Multi Loose Tube Non-Metallic Fiber Optic Cable is designed for outside plant, which is prone to electrical interference. Optical Fiber Core could be applied as G. A2, OM1, OM2, OM3, OM4 according to needs. Standard: TS EN 60794 +20 C -20 C +70 C +20 C -Number of cycles: 2 turns -Time per each step: 12 hrs.
