Fiber sleeves

Fiber sleeves

Fiber optic protection sleeves are essential accessories used in fiber optic splicing to safeguard the delicate splice joint. These sleeves consist of a heat-shrinkable outer tube, a strength member (typically stainless steel or ceramic rod), and an inner tube to secure the fiber. When heated, the sleeve shrinks and tightly seals the splice, providing strong mechanical protection and environmental resistance against moisture, dust, and bending stress. Fiber sleeves are transparent or semi-transparent, allowing easy inspection of the splice without removal. Widely used in telecommunications, data centers, and networking, they ensure long-term durability, stability, and reliability of fiber optic connections.
