288 Optical Cable Vertical Opening

A 288-core vertical fiber optic splice closure is a high-capacity, outdoor enclosure designed for splicing, distribution, and future expansion of optical cables with IP68 protection.

Key Features

Capacity and Splicing: The closure supports up to 288 fibers, typically organized in 12 splice trays with 24 fibers per tray, allowing for efficient fiber management and future expansion of up to 20% additional capacity ( ). Each tray is designed to maintain proper fiber curvature and prevent signal loss. Cable Ports and Entry: Vertical closures usually feature multiple round ports (typically 6–16) and one oval port to accommodate various cable diameters up to 38 mm. Heat-shrink sealing ensures waterproof entry, and the design allows flexible cable entry angles for branching and network expansion ( [5^]). Material and Durability: Constructed from high-impact, UV-resistant engineering plastics, these closures are corrosion-resistant, flame-retardant, and suitable for harsh outdoor environments. They are designed to withstand acid, alkali, and salt exposure, as well as extreme weather conditions ( ). Environmental Protection: Most 288-core vertical closures are rated IP68, providing full protection against dust and water ingress, making them suitable for aerial, pole-mounted, underground, or manhole installations ( ). Maintenance and Re-entry: Closures are designed for repeatable opening, allowing adds, moves, or changes without compromising sealing. Splice trays are often turnable like booklets, ensuring proper fiber management and curvature radius compliance ( ). Applications: These closures are widely used in FTTH, FTTB, FTTA, PON, GPON, WAN/LAN, telecom, and CATV networks, supporting high-density branching and future network growth ( ).

Installation Considerations

• Port Matching: Ensure the cable outer diameter matches the port OD to maintain sealing integrity and prevent water ingress ( ).
• Tray Strategy: Choose between 24-core or 48-core trays depending on re-entry frequency and network complexity ( ).
• Mounting Options: Supports wall-mounting, pole-mounting, and aerial hanger installation ( ).
• Splitter Integration: Some models include slots for mini PLC splitters, enabling efficient optical signal distribution within the closure ( ).

Summary

A 288-core vertical fiber optic splice closure is ideal for high-density, outdoor fiber networks requiring long-term reliability, flexible cable management, and easy maintenance. Its combination of IP68 protection, modular splice trays, and robust materials ensures durability and scalability for complex optical distribution networks ( ).
