Product Description

Product 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.
