Self-supporting butterfly optical cable places the optical communication unit (multimode dual-core) at the center, with two parallel steel wires on both sides, and an additional steel wire reinforcement element on the outer side, finally extruding a black or colored low-smoke. Self-supporting butterfly optical cable places the optical communication unit (multimode dual-core) at the center, with two parallel steel wires on both sides, and an additional steel wire reinforcement element on the outer side, finally extruding a black or colored low-smoke. Self-supporting butterfly optical cable places the optical communication unit (multimode dual-core) at the center, with two parallel steel wires on both sides, and an additional steel wire reinforcement element on the outer side, finally extruding a black or colored low-smoke halogen-free sheath to. 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. Outdoor single-mode double-core butterfly cable is the signal transmission carrier of modern communication. Once it is not properly protected during on-site construction, once it is damaged, it will cause great losses. Cable size is outer diameter of the round cable; 3. The minimum bend radius (static) is 5H when G657 fiber is used. 01 The cable consists of optical communication unit, strength member. Shenzhen J. It is a high-tech enterprise dedicated to developing and utilizing high technology to provide professional ICT technology products and services to global users,help them achieve digital and intelligent transformation. However, there are also specialty fibers containing multiple cores, which may e.
