5er Link Technology Fiber Optic Fusion Splice Sleeves enable to secure one or twelve fibers in one sleeve. Excellent climatic and thermal properties make it ideal for use in closed as well as open spaces. The main goals during design phase were: full protection of the fiber optic splices and quickness of assembly. Initial shrinking of the sleeve was taken into account during the production process to reduce the gap between the tubes. This protects the internal tube and ceramic strengthening element from falling out. The sleeves we produce offer full protections the fiber optic splices. They do not cause additional insert losses, and they offer protection against mechanical damage, pollution and weather conditions. These protector sleeves provide a way to support and protect a fiber optic fusion splice. As the sleeve is somewhat rigid it does help provide some protection to the splice area. The protector sleeves themselves are easy to install which means the potential for damage to the splice is minimal. The splice sleeves are heat shrinkable. Once the fusion splicing has taken place and alignment is correct, heat is applied and the sleeve shrinks to provide environmental protection to the splice.
