The 24-48 Core Fiber Optic Outdoor Dome Enclosure (also known as a dome-type fiber optic splice closure or joint box) is a protective housing designed for outdoor termination, splicing, and distribution of optical fiber cables in harsh environments. It supports 24 to 48 fiber cores, making it ideal for FTTH (Fiber to the Home), telecom networks, and enterprise applications. The dome shape provides a compact, weather-resistant design for aerial, pole, wall, duct, or direct-buried installations. The “-24 Core” in your query likely refers to a base configuration starting at 24 cores, with scalability up to 48.

These enclosures protect fiber splices from moisture, dust, corrosion, and UV exposure while allowing easy access for maintenance. They typically include modular splice trays, cable entry ports (e.g., 2-4 ports), and grounding mechanisms.

Key Features

• Capacity: Supports 24-48 fiber cores (e.g., one tray for 24 cores, up to 2 trays for 48 cores). Modular design allows expansion.
• Material: High-strength engineering plastics (e.g., modified PP or PC) for lightweight, anti-aging, and corrosion resistance.
• Environmental Protection: IP65 or IP68 rated, with rubber seals, weatherproof locks, and anti-UV properties for outdoor use in extreme conditions (e.g., rain, dust, temperatures from -40°C to +65°C).
• Ports and Sealing: 2-4 cable entry/exit ports (e.g., 2 in/2 out); mechanical or heat-shrink sealing for quick, reliable installation.
• Mounting Options: Wall, pole, or bracket-mounted; includes galvanized steel brackets in some models.
• Additional Components: Splice trays for fusion splicing, patch panels (e.g., 12/24 positions for SC/ST/FC connectors), fiber storage loops, and insulation grounding.
• Standards Compliance: RoHS, CE certified; compatible with single-mode (SM) or multi-mode (MM) fibers.
