Our Ribbon Fiber Protection Sleeve is designed specifically for protecting fusion splice points of multi-core ribbon fiber cables, including 4, 6, 8, and 12 fiber configurations. Engineered for long-lasting performance and ease of installation, these sleeves combine high-quality materials like ceramic strengthening rods, heat-shrinkable polyolefin tubes, and EVA meltable adhesive to ensure maximum splice protection and signal integrity.
Whether used in fiber optic closures, splice trays, or FTTx distribution boxes, this Ribbon Fiber Protection Sleeve provides superior mechanical strength and environmental sealing to support and safeguard ribbon fiber splices. It’s an essential accessory for installers seeking reliable performance in high-density fusion splicing operations.
What is a Ribbon Fiber Protection Sleeve?
A Ribbon Fiber Protection Sleeve is a heat-shrinkable protective device that covers the fusion splice point of ribbon fiber optic cables. The sleeve rebuilds the fiber’s coating and protects it from mechanical damage, moisture, and temperature variations. It ensures long-term durability while maintaining minimal signal loss and a secure, neat installation.
Each sleeve includes:
- A ceramic bar or bars to provide structural strength
- An inner meltable adhesive layer (EVA)
- A clear, heat-shrinkable outer tube made of cross-linked polyolefin
Product Structure
| Component | Material | Function |
|---|---|---|
| Outer Tube | Cross-linked polyolefin | Transparent for visibility; UV and impact-resistant |
| Inner Tube | EVA adhesive | Melts upon heating to encapsulate the splice |
| Reinforcing Rod(s) | High-strength ceramic | Prevents fiber bending or stress at splice |
Key Features
- Protects fusion splice joints from bending, impact, and moisture
- Reliable sealing structure ensures long-term resistance to temperature and humidity
- Fast shrink time at 120°C, reducing installation time
- Transparent sleeve for visual inspection during and after installation
- High mechanical performance (18MPa tensile strength, 700% elongation)
- Wide temperature range (-55°C to +100°C) for diverse indoor/outdoor applications
- Available in multiple sizes: 6F, 8F, 12F – single and double ceramic bar configurations
- RoHS and IEC compliant for international telecom standards
- Convenient packaging: 50 pcs/bag, with bulk options up to 1000 pcs/pack

Applications
Our Ribbon Fiber Protection Sleeves are widely used in:
- Fiber optic splice closures
- Fusion splice trays
- Optical distribution frames (ODF)
- FTTx installations
- Data centers and telecom rooms
- Backbone cable splicing
- High-density cable management environments
These sleeves ensure high reliability in indoor, outdoor, and underground installations where multiple fiber splices need protection from mechanical stress and environmental exposure.
Easy Installation
Installation of the Ribbon Fiber Protection Sleeve is straightforward:
- Slide the sleeve over one end of the fiber before splicing.
- Complete the fusion splice.
- Center the sleeve over the splice point.
- Apply heat with a shrink oven or heat gun until the adhesive flows and the sleeve conforms tightly around the splice.
Its fast shrink time at a minimum temperature of 120°C makes it ideal for time-sensitive deployments without compromising performance.
