Secondary fiber distribution box for direct melting

A direct-melting optical fiber distribution box allows single-person installation, protects fibers, and improves efficiency and service life.

Overview

A direct-melting fiber distribution box is a specialized optical fiber enclosure designed for direct fusion (melting) splicing of fibers. It serves as a central point for terminating, splicing, and distributing optical fibers while ensuring protection and organization of delicate cables . Unlike traditional boxes, it is engineered to reduce manpower requirements, allowing installation and disassembly by a single person, which enhances work efficiency and convenience .

Key Components and Features

• Fiber Box Body: The main enclosure that houses the fiber splices and pigtails.
• Box Door with Lock: Provides secure access to the internal components.
• Elastic Member and Protective Top Plate: Absorbs impact from external forces such as hail or falling objects, prolonging the box's service life .
• Support Slides and Limit Baffles: Ensure the protective top plate remains stable and prevents accidental displacement.
• Optical Cable Protection Tubes: Guide and protect fibers entering and exiting the box.
• Mounting Device: Allows the box to be fixed on walls, poles, or cylindrical surfaces using screws or hoops, enabling single-person installation .

Advantages

• Manpower Efficiency: Only one person is needed for installation or maintenance, reducing labor costs.
• Enhanced Safety: Protective top plate and elastic components buffer external impacts, safeguarding fibers.
• Improved Service Life: Durable design and protective features extend operational lifespan.
• Flexible Mounting: Can be installed on various surfaces, including open-air environments, walls, or poles.
• Compatibility: Supports multiple fiber types and connector interfaces, including SC, LC, and PLC splitters .

Applications

Direct-melting fiber distribution boxes are widely used in FTTH, FTTx, ISP, and telecom access networks. They are suitable for both indoor and outdoor installations, providing organized fiber management and easy access for maintenance or network expansion . They are particularly beneficial in environments where rapid deployment and minimal labor are critical.

Summary

A secondary fiber distribution box for direct melting combines efficient installation, robust protection, and flexible mounting. Its design reduces manpower needs, safeguards fibers from environmental hazards, and ensures reliable network performance, making it ideal for modern optical fiber networks .
