Heat Shrinkable Sealing Fiber Optic Splice Dome Closure
Heat Shrinkable Sealing Fiber Optic Splice Dome Closure
Vertical dome closure fiber optic looks like a dome, thus it is also called dome fiber optic splice closure or fiber dome closure. The dome shape makes it easy to be buried in many applications, though it also can be used above-ground as well. Due to the growing network demands, there is a wide range of models and configurations of vertical fiber optic splice closures. High-capacity versions and variations in the number of splicing trays are also available in the market to meet the complex needs of today’s fiber-optic networks. The number of inlet/outlet ports of the dome fiber optic closure also varies with application needs. Dome fiber optic splice closure requires high-levels seals and waterproof technology, due to its underground applications. Besides, keeping insects and dirt out is also important for underground closures.
