Fiber Optic Splice Closure is a fiber management product typically used with outdoor fiber optical cables. It provides space and protection for the fiber optic cable splicing and joint. Fiber splice closure is used for aerial, strand-mount FTTH "tap" locations where drop cables are spliced to distribution cables. Fiber-Mart supplies two types of fiber splice closures which are the horizontal (inline) type and the vertical (dome) type. Both are made of excellent engineering plastics to be waterproof and dust proof. And with various ports types, they can fit different fiber optic core numbers. More details about splice closure.
