DESCRIPTION
The Fiber Fusion Protection Sleeve is a vital component in any fiber optic installation, designed to protect fusion splices with a strong, durable, and transparent structure. These sleeves prevent mechanical damage, moisture ingress, and environmental stress — all while keeping the optical fiber perfectly aligned inside.
Available in standard lengths of 40mm, 45mm, and 60mm, these sleeves are ideal for various cable management solutions and splice enclosures. They offer easy installation and quick heat shrinking with a hot air tool or fusion splicer oven, making them a staple in fieldwork and factory patch cord production.
FEATURE DETAILS
- Three-Layer Construction: EVA inner tube, stainless steel strength rod, and polyolefin heat-shrink outer layer
- Clear Design: Allows visual confirmation of splice integrity
- Low Shrink Temperature: Efficient bonding without damaging the fiber
- Reinforced Rod: Stainless steel rod adds pressure resistance and alignment protection
- Quick Shrinking: Fast fusion time reduces installation delays

APPLICATION DETAILS
- Slide sleeve over the fiber before splicing.
- After fusion, center the sleeve over the splice point.
- Heat evenly using a splice heater or heat gun until the sleeve shrinks and seals the splice.
- Wait a few seconds for cooling before placing the fiber in a tray or box.
FAQ
Q1: What sizes are available?
40mm, 45mm, 60mm, and custom lengths.
Q2: Can they be used for both SM and MM fibers?
