This is the industry's most popular, high-quality fusion splice protection sleeve.
It has a steel strength member, inner fiber tube, and outer shrink tube. After heat shrinking the size is 3.0mm diameter x 60mm length.
It is designed for single fiber applications and accommodates up to 1.4mm coated fibers. The color is clear (transparent).
Fusion splice protection sleeves provide vital protection at the fused juncture between two fusion spliced optical fibers. In addition to providing a substitute for the original fiber optic cable jacket, splice protection sleeves provide a degree of rigidity that prevents the spliced area from bending or flexing.
