Fiber Optic Cable Reserved Back Box

A Fiber Optic Cable Reserved Back Box is a storage enclosure designed to safely coil and reserve excess fiber optic cable for future use or splicing in FTTH and other fiber networks.Purpose and Function

A fiber optic reserve box, also called a fiber storage or reservation box, is used to store excess fiber optic cable before it is terminated or spliced. It ensures that the fiber remains protected from physical damage, dust, and moisture while maintaining proper bend radius to prevent signal loss. These boxes are particularly useful in FTTH (Fiber to the Home), CATV, and LAN networks, where cable management and future expansion are critical ( ).

Key Features

• Capacity: Depending on the model, reserve boxes can store fiber lengths from 20 meters up to 30 meters ( ).
• Materials: Commonly made from PC, aluminum alloy, steel, or ABS plastic, providing durability and lightweight handling ( ).
• Design: Compact and mechanically stable, with removable trays for easy cable management. They include cable fixing units, bend radius protection, and routing paths to prevent fiber damage ( ).
• Environmental Protection: Many boxes are designed for indoor and outdoor use, featuring dust-proof doors and water-proof sealing rings ( ).
• Splicing Support: Some models allow mechanical splicing or fusion splicing of drop cables directly inside the box ( ).

Applications

• FTTH Networks: Storing drop cables before connecting to the optical network terminal.
• Telecommunication Networks: Managing excess fiber in distribution points.
• CATV and LAN Networks: Organizing fiber for short-distance or local network connections.
• Future Expansion: Reserve boxes allow additional fiber to be stored for network upgrades without re-laying cables ( ).

Installation Considerations

• Mounting: Can be wall-mounted or installed on racks depending on network layout.
• Accessibility: Designed for easy access to fiber for splicing or rerouting.
• Protection: Ensure proper bend radius and secure clamping to avoid fiber stress or breakage ( ). In summary, a Fiber Optic Cable Reserved Back Box is an essential component for fiber network management, providing a secure, organized, and expandable solution for storing and handling excess fiber optic cables safely and efficiently.
