Fiber Optic Joint Closure Box – 48 Core

A compact Fiber Optic Joint Closure Box designed to protect and manage up to 48 fiber splices. Ideal for distribution-level networks and smaller fiber deployments in outdoor and underground environments.

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 environmental damage
• Strain Relief – Secures cables to prevent tension and breakage

Main Features

• Supports up to 48 fiber cores (splices)
• Suitable for aerial, duct, and direct burial installations
• Durable industrial-grade ABS/PC plastic construction
• Fully sealed with mechanical or heat-shrink sealing system
• Includes:
  • Splice trays
  • Cable sealing components
  • Mounting accessories
• Compact design for easy installation and maintenance

Where It’s Used

• FTTH distribution networks
• Residential and estate installations
• Underground fiber routing
• Pole-mounted aerial deployments
• Fiber repair and branch points

How It Works (Simple Flow)

1. Fiber cables enter through sealed ports
2. Fibers are stripped and arranged in splice trays
3. Fusion splicing is completed
4. Closure is sealed to protect internal connections

Common Configurations

• Up to 48 fiber splices
• Multiple cable entry ports (model dependent)
• Supports single-mode (SMF) and multi-mode (MMF) fibers

Why It Matters

• Ideal for medium-scale fiber distribution
• Protects connections in outdoor environments
• Ensures stable signal performance
• Supports network expansion and maintenance
