General Specifications
The fusion spliced region of the fiber is bare glass and thus needs to be protected. Various systems designs are used to carry this out. Heat shrinkable or thermo shrinking type is the most popular method used to protect spliced fiber. It is easy, convenient and reliable method to protect bare fiber. As most splicing machines come with an oven no special tools are generally required to carry out such an installation. As the most commonly used method, familiarity with the process has become virtually universal with industry personnel.
The thermo shrinking type of splice protection sleeves consists of three parts, the outer heat shrinkable tubing, the inner hot melt adhesive tubing and the strength member. The inner hot melt adhesive melts and adheres to the fiber and the outer tubing shrinks to completely encapsulate it. The strength member gives mechanical strength to the sleeve preventing bending and allowing the sleeves to be arranged in splicing trays conveniently.
