Product Overview

The Fiber Optic Heat Shrink Tube is a professional optical protection component, specifically designed for the insulation, waterproofing, and mechanical protection of fiber optic splicing joints (fusion splicing/cold splicing) in FTTH (Fiber to the Home), ODN (Optical Distribution Network), telecom communication, data centers, and outdoor fiber optic projects. It is made of high-quality cross-linked polyolefin material, with built-in EVA hot melt adhesive, which shrinks uniformly when heated, tightly wrapping the splicing joint to form a sealed, moisture-proof, and anti-corrosion protective layer. The tube features low shrink temperature, fast shrink speed, good flexibility, and strong adhesion, compatible with various specifications of bare fibers, pigtails, and drop cables. It effectively isolates moisture, dust, and external mechanical damage, ensures stable signal transmission, and extends the service life of fiber optic splicing joints, making it an essential supporting component for fiber optic splicing projects.
