Fiber optic splice protection sleeves Extralink 150 pcs — arc/crimp splice protection

Heat-shrink splice protection sleeves by Extralink, pack of 150 pieces, are designed to protect fiber optic fusion and mechanical splices. Each sleeve combines a heat-shrink outer tube and an inner reinforcement member to provide mechanical support, strain relief and environmental sealing. These splice protection sleeves help prevent microbending and moisture ingress, extending the reliability of spliced fibers in telecom, FTTH and data center applications.

Advantages

Extralink splice protection sleeves provide a compact and durable method to reinforce and seal arc and crimp splices without adding significant bulk. The heat-shrink construction ensures a snug fit over splices, while the internal strength member distributes mechanical loads and reduces the risk of fiber damage during handling and installation. The sleeves are suitable for repeated field use and enable consistent protection for a large number of splices thanks to the 150-piece quantity.

Suitable for

• Fiber optic fusion splicing (arc splices)
• Mechanical or crimp splices
• FTTH network deployments and repairs
• Telecom backbone and access cabling
• Data center fiber maintenance and emergency repairs

Key specifications

• Pack quantity: 150 pieces
• Type: heat-shrink splice protection sleeve with internal reinforcement
• Protection: mechanical support, strain relief and environmental sealing
• Compatibility: designed for standard single-mode and multimode fiber splices
• Application temperature: suitable for standard fiber optic splicing and heat-shrink processes

How to use

Slide a splice protection sleeve over one fiber before performing the splice or position it over the completed splice. After fusion or mechanical connection, center the splice inside the sleeve, then apply heat uniformly to the outer tube until it shrinks and conforms around the internal reinforcement. Allow the sleeve to cool so the internal member sets and provides strain relief. Use appropriate heat sources and follow standard fiber handling procedures to avoid damaging the fiber.

Usage recommendations

Use compatible heat sources and controlled heating to achieve uniform shrinkage; avoid excessive localized heat. Store sleeves in a dry, dust-free environment and handle fibers with standard ESD and contamination precautions. For critical installations, verify splice integrity and optical loss after protection is applied.
