Model of fiber optic cable splicing protective sleeve

Common models include AFL FP-03, FP-04(T)/05, Fujikura FPS01/FPS04 series, and CommScope SMOUV heat-shrink sleeves.

Overview of Protective Sleeve Models

AFL Series:

• FP-03: Standard for single-fiber splices, providing durable protection for field installations .
• FP-04(T)/05: Designed for 8- or 12-fiber ribbon splices, offering the same performance as FP-03 for multi-fiber applications .
• FPS01 and FPS04: Micro sleeves for optical components where compact packaging is critical, available in various lengths and coating sizes . Fujikura Series:
• FPS01-400 and FPS01-900: Micro sleeves with a strength member slightly longer than the tube, designed for precise fusion splicing and environmental protection .
• These sleeves protect the splice from impact and bending, ensuring stable communication quality . CommScope SMOUV Series:
• Single Fusion Heat Shrink Sleeves: For individual fiber splices, available in various packaging sizes .
• 12-Fiber Ribbon Heat Shrink Sleeves: For multi-fiber ribbon splices, providing mechanical and environmental protection .
• ANT Protective Sleeves: Packaged in bulk for field deployment .

Construction and Features

• Outer Heat-Shrink Tube: Made from polyolefin, providing abrasion resistance and environmental sealing .
• Inner Hot-Melt Adhesive Layer: Bonds the fiber and sleeve during heat shrinking, creating a waterproof seal .
• Strength Member: Stainless steel or ceramic rod ensures mechanical stability, prevents bending, and maintains fiber alignment .
• Clear Outer Tube: Allows visual inspection of the splice before shrinking .
• Fast Shrinking Time: Compatible with standard fusion splicer heating ovens for efficient field application .

Applications

• Single-Fiber Splices: FP-03, FPS01, SMOUV single fusion sleeves.
• Multi-Fiber Ribbon Splices: FP-04(T)/05, SMOUV 12-fiber sleeves.
• Compact Optical Modules: FPS01/FPS04 micro sleeves.
• Environmental Protection: All models provide moisture, dust, and mechanical stress protection, suitable for indoor and outdoor installations . These models are widely used in FTTH, FTTx, and backbone networks, ensuring long-term reliability and minimal signal loss. Selecting the appropriate sleeve depends on fiber count, installation environment, and splicer compatibility.
