1. Product Overview

Huijue Group Fiber Fusion Splice Protection Sleeve is designed to protect fusion-spliced optical fibers in fiber optic communication networks. It provides mechanical reinforcement and environmental protection at the splice point, helping maintain reliable optical connections during installation and long-term operation.

The sleeve consists of a cross-linked polyolefin heat-shrink tube, a hot-melt adhesive tube, and a reinforced 304 stainless-steel rod. Available in single-fiber and 12-fiber configurations, it offers a practical solution for protecting individual fiber splices and ribbon fiber connections.

The transparent outer tube allows visual inspection of the splice before and during the shrinking process, while the sealed structure helps protect the joint against moisture and environmental exposure.

2. Key Features

• Reliable Splice Protection: Reinforces fusion-spliced fibers and helps prevent damage during installation and handling.
• Heat-Shrink Construction: Cross-linked polyolefin tubing shrinks under heat to secure the splice protection assembly.
• Stainless-Steel Reinforcement: The 304 stainless-steel rod provides additional mechanical strength and helps protect the fiber joint.
• Transparent Outer Tube: Allows visual inspection of the splice position during installation.
• Moisture Protection: The hot-melt adhesive helps seal the splice area against moisture and environmental exposure.
• Single-Fiber and 12-Fiber Options: Suitable for individual fiber splices and compatible ribbon fiber applications.
• Easy Installation: Designed for convenient use with standard fiber fusion splicing and heat-shrink procedures.

3. Product Description

Reliable Protection for Fiber Fusion Splices

Fiber fusion splicing joins two optical fibers to create a continuous transmission path. Although the splice provides low optical loss when properly executed, the joint itself requires additional mechanical protection to prevent bending, tension, and accidental damage.

Huijue Group fusion splice protection sleeves provide a protective enclosure around the splice point. The reinforced structure helps maintain the integrity of the joint during cable installation, fiber tray organization, and routine maintenance.

Heat-Shrink Sealing Structure

The sleeve combines a heat-shrink outer tube, a hot-melt adhesive layer, and a stainless-steel reinforcement rod. When heated using a suitable fusion splicer oven or splice protection heater, the outer tube contracts and the adhesive helps seal the assembly around the splice.

This structure provides mechanical support and helps reduce the risk of moisture reaching the protected joint. Proper heating and installation are important to achieve consistent protection.

Multiple Configurations for Fiber Networks

Different fiber management systems require different splice protection formats. Single-fiber sleeves are suitable for individual fusion splices, while 12-fiber versions are designed for compatible ribbon fiber applications.

The appropriate sleeve length and diameter should be selected according to the splice tray, fiber type, and installation equipment to ensure proper fit and reliable protection.

4. Applications

• FTTH Networks: Protects fusion splices in fiber-to-the-home access networks.
• Telecommunications Networks: Provides splice protection in optical cable joints and distribution systems.
• Fiber Optic Splice Closures: Protects fiber joints inside compatible splice closure trays.
• Optical Distribution Frames: Supports organized fiber splice management in communication rooms.
• Data Centers: Protects fusion-spliced fibers in structured optical cabling systems.
• Backbone and Access Networks: Helps maintain mechanical protection at fiber splice points in network infrastructure.

5. Technical Specifications

Note: Sleeve dimensions, shrink temperature, post-shrink diameter, and applicable fiber configurations should be confirmed according to the selected product specification.
