① Special bending resistant optical fiber provides large bandwidth and good communication transmission characteristics; ② Two parallel FRP or steel wires have good compressive performance to protect the optical fiber; ③ Unique groove design, easy to separate, convenient to. ① Special bending resistant optical fiber provides large bandwidth and good communication transmission characteristics; ② Two parallel FRP or steel wires have good compressive performance to protect the optical fiber; ③ Unique groove design, easy to separate, convenient to. The invention discloses a reinforced self-supporting butterfly-shaped optical cable which comprises an optical cable body, wherein a reinforced protection assembly is movably arranged in the optical cable body, the reinforced protection assembly comprises four fixed compression resistant plates, a. 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. An additional steel wire strength member is attached to the outer side, followed by extrusion with black low smoke. GJYXCH [Metal Reinforcement, LSZH Sheath, Galvanized Steel Rope Hanging Wire, Self Supporting Butterfly shaped Introduction Optical Cable] The optical cable structure is to place the optical fiber between two parallel reinforcement pieces, and at the same time, place a metal galvanized steel rope. 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. For self-supporting access network, the butterfly introduction of indoor optical cable positions the communication unit in the center, with two parallel non-metallic strength members (FRP) placed on both sides.
