Splice closures (aka Joint closures) are weatherproof enclosures used to splice 2 or more optical fibre cables. They come in either rectangular or cylindrical construction. The splice closures have 2 -4 cable entry ports to bring the the cables in, splice trays for joining the individual fibres of the cables to each other and properly routing the same. Upon splicing the cable entry ports are sealed with heat shrinkable sleeves. There is also a mechanical design which enables re-opening of the closure if required. The closures are made out of light weight plastic. Once properly sealed the closure is water proof and air tight. Hardware used in the closure is rust proof. The closure generally conforms to IP-68 and suitable for underground direct burial, aerial or duct burial applications.
