Mechanical Sealing Splice Dome Closure
Mechanical Sealing Fiber Optic Splice Dome Closure
The outdoor fiber optic enclosure is a passive component which can provide a great protection for fiber splicing point. Aerially assembling, pipeline assembling or buried underground are all available. Generally, closures have two types to face different situations: Cap (Vertical) Type and Half (Horizontal) type. The Cap type closure is also called Vertical closure. The input and output ports are at the bottom of the closure. This closure type is more suitable for the application on accessing layer. The Half type closure is also called Horizontal closure. The input and output are on the both sides. This closure is more suitable for backbone application.
