Introduction: Dome Splice Closure also named Vertical Fiber Optic Splice Closure, it is used to distribute, splice, and store the outdoor optical cables which enter and exit from the ends of the optical fiber cable joint closure. Vertical fiber optic splice closure is an essential passive component for fiber optic cable management in the fiber-optic network of backbone and access network. The fiber splice closures and the splice trays inside provide strong protection for the spliced fiber joint and fiber cables. Fiber optic splice closure can be installed in aerial, pole mounting, wall mounting, direct buried, and duct mounting, which is used for direct connection during the optical fiber transmission process. With good sealing performance, the simple installation and wide application range are the best choices for optical fiber connection. Application: Dome Vertical fiber optic splice closure are used to distribute, splice, and store the outdoor optical cables which enter and exit from the ends of the closure. The high-quality dome splice closure provides space and protection for the fiber optic cable splicing and joint and capacity from 24~576 core. The vertical splice closure is with a great sealing performance used in aerial, duct and direct buried application • Ideal for FTTH/FTTX network • Installation application direct buried, aerial, pole mounting and wall mounting • Excellent Mechanical Sealed to protect fiber and splice ensuring durability Operation Features: Dome Vertical fiber optic splice closure is a fiber management product typically provide for good splicing and protection with outdoor fiber optical cables. Inline fiber splice enclosure is used for aerial, underground, pipeline, hand-holes assembling. The Vertical type closure is also called Dome closure. The input and output are on the bottom side. Dome closure is more suitable for backbone application. All the splice closures we offered are with a great sealing performance with the following features • IP rating is IP68 • Capacity from 24~576 core • Cable ports up to 7 ports (1 oval & 6 round) • Used for direct buried, aerial, pole mounting and wall mounting applications • High reliability • Advanced internal structure design • Using a special material that can be repeatedly opened, re-use • Splice tray easy to installation • Large operating temperature range • Customized packaging and configuration Mechanical Performance Test compliance: IP rating: IP68 Cable ports: up to 7 ports (1 oval & 6 round) Cable Diameter: Φ7—Φ23(mm) Splice Trays: 12 or 24 Cores trays Splice Capacity: 24~576 Cores Operation Temperature: -40 to +60°C Storage Temperature: -40 to +70°C
