Fiber Optic Joint Closure Box (Dome Type) – 12 Core

A compact dome-type Fiber Optic Joint Closure Box designed to protect and manage up to 12 fiber splices. Ideal for small-scale fiber deployments, repairs, and last-mile FTTH connections.

Key Functions

• Fiber Splicing – Provides secure space for fusion splicing
• Cable Jointing – Connects and branches fiber optic cables
• Sealing & Protection – Protects fibers from water, dust, and weather
• Strain Relief – Secures cables to prevent tension damage

Main Features

• Supports up to 12 fiber cores (splices)
• Dome (vertical) design for efficient sealing and durability
• Suitable for aerial, duct, and wall-mounted installations
• Made from high-strength ABS/PC plastic
• Fully sealed with mechanical or heat-shrink sealing system
• Includes:
  • Splice tray
  • Cable sealing components
  • Mounting accessories
• Compact and lightweight for quick installation

Where It’s Used

• FTTH last-mile connections
• Small distribution points
• Fiber repair and maintenance
• Residential and small business installations
• Pole-mounted or wall-mounted setups

How It Works (Simple Flow)

1. Fiber cables enter through sealed ports
2. Fibers are stripped and arranged in the splice tray
3. Fusion splicing is completed
4. Dome closure is sealed to protect all internal connections

Common Configurations

• Up to 12 fiber splices
• 1 splice tray (expandable depending on model)
• Supports single-mode (SMF) and multi-mode (MMF) fibers

Why It Matters

• Perfect for small-scale and last-mile deployments
• Protects fiber joints in outdoor conditions
• Ensures stable signal performance
• Cost-effective solution for basic fiber distribution
