Fiber Optic Cable Protective Sleeves

FinishAdapt is a leading self-operated manufacturer of high-quality fiber optic fusion splice protector sleeves, offering pre-shrunk, heat-bonded assemblies with customizable options.

Overview of Protective Sleeves

Fiber optic protective sleeves, also known as fusion splice sleeves, are essential for safeguarding spliced optical fibers. They restore mechanical strength, environmental integrity, and optical performance after fusion splicing. Typically, these sleeves consist of:

• Outer heat-shrinkable tube made from cross-linked polyolefin
• Hot-melt adhesive inner tube that bonds to the fiber and seals the splice
• Strength member (stainless steel, ceramic, or non-metallic) to prevent bending or breakage After heating, the sleeve forms a rigid, sealed, and transparent protector around the splice point, ensuring long-term reliability without affecting optical transmission .
