Fiber optic splice closure is the equipment used to offer room to fuse splice optical fiber and also to provide protections for the fused fiber joint point and the fiber cables. Typical fiber optic splice closures are vertical type and horizontal type, there are various kinds of fiber splice closures suit for different applications, such as aerial, duct fiber cables, and direct buried. Generally, fiber optic splice closures are used outdoors, some even used underwater.

For outside plant splice closure, there are two major types: horizontal splice closure and vertical splice closure. Below are the details of them.

• In-line/horizontal type fiber optic splice closures

Horizontal types closure look like a flat or cylindrical case, they provide space and protection for fiber optic cable splicing and joint. They can be mounted aerial, buried, or for underground applications. Horizontal types are used more often than vertical type (dome type) closures.

Most horizontal fiber optic splice closures can fit hundreds of fiber connections. They are designed to be waterproof and dustproof. They can be used in temperatures ranging from -40°C to 85°C, can accommodate 70 to 106 kpa pressure and the case are usually made of high tensile construction plastic.

• Dome/vertical Type fiber optic splice closures

The vertical type of fiber optic splice closure looks like a dome, thus they are also called dome type. They meet the same specification as the horizontal types. They are designed for buried applications.
