Looking for high-quality, affordable fusion splice sleeves for your fiber optic splicing projects? Our 60mm Fusion Splice Sleeve is engineered for maximum protection, durability, and easy visual inspection during and after the fusion splicing process. These heat shrinkable sleeves are trusted by network technicians, telecom contractors, and data center professionals around the world for providing long-term mechanical strength and environmental protection for spliced optical fibers.
Our Fusion Splice Sleeves are designed to reinforce and protect the splice point between two fusion-spliced fibers, replacing the fiber’s original jacket and minimizing the risk of breakage. Whether you’re building a new FTTH network or repairing an existing line, these sleeves provide a low-cost, high-reliability solution to safeguard fiber joints.
What is a Fusion Splice Sleeve?
A fusion splice sleeve is a fiber optic component used to protect the junction where two optical fibers are fusion-spliced together. After the fusion splicing process, the fragile exposed splice is covered with a heat-shrinkable tube, which contains a strength member and an inner adhesive layer. When heat is applied, the sleeve shrinks to form a tight, protective seal over the fiber, restoring structural integrity and shielding the splice from physical stress and environmental damage.
Product Features
- 60mm Standard Length – Industry-standard size for most fusion splice applications
- Clear Outer Tube – Allows for easy inspection of the fiber color and alignment
- Heat Shrinkable Design – Shrinks uniformly to protect and reinforce the splice
- 3.0mm Outer Diameter After Shrink – Compatible with most splice trays and holders
- Stainless Steel Strength Member – Prevents bending or flexing at the splice point
- Dual-layer Construction – Combines strength and adhesive seal for enhanced performance
- Easy to Use – Designed for compatibility with all major fusion splicers
- Packaged in 50 Sleeves per Bag – Convenient bulk packaging for installers
Why Use Fusion Splice Sleeves?
When two optical fibers are fusion-spliced, the result is a single strand of glass with a vulnerable joint at the connection point. Without protection, this exposed splice is susceptible to:
- Mechanical stress or strain
- Moisture ingress
- Dust contamination
- Fiber breakage due to handling or installation pressure
Our Fusion Splice Sleeves eliminate these risks by encapsulating the splice within a clear, rigid, and sealed sleeve. The stainless steel rod inside provides added rigidity to prevent flexing, while the inner adhesive melts during shrinking to bond with the fiber coating for a secure, moisture-resistant seal.

Applications
Our Fusion Splice Sleeves are ideal for a wide range of fiber optic splicing and installation scenarios, including:
- FTTH (Fiber to the Home) Installations
- Data Centers and Enterprise Networks
- Telecommunications Backbone Splicing
- Splice Closures and Fiber Management Trays
- Aerial, Duct, and Underground Fiber Deployments
- Maintenance and Emergency Repair Work
They’re compatible with single-mode and multimode fibers and work seamlessly with all standard fusion splicing machines and heat ovens.
Visual Monitoring & Quality Assurance
Our sleeves feature a clear outer tube, allowing technicians to:
- Confirm the fiber is centered correctly
- Check for color-coded identification
- Monitor shrinkage and adhesion during the splicing process
- Verify proper installation during periodic maintenance
Visual inspection is a key part of quality control in fiber splicing, and this feature reduces rework and ensures splicing precision.
How to Use a Fusion Splice Sleeve
- Slide the sleeve over one side of the fiber before fusion splicing.
- Perform the fusion splice with your fusion splicer.
- Center the sleeve over the exposed splice point.
- Place in a heat shrink oven or integrated sleeve heater.
- Allow the sleeve to shrink and bond securely to the fiber.
- Let cool, then mount into your splice tray or holder.
