Fiber Optic Splice Closure is devices used to provide space for splicing fibers. It also provides protection for fused fiber splice points and fiber optic cables. There are two main types of closure: vertical and horizontal. A wide variety of fiber optic splice closures are designed for different applications such as antennas, ducted fiber optic cables and direct burial. Generally, they are usually used in outdoor environments, even underwater.
Fiber optic connector closure type
For external plant joint closures, there are two main types: horizontal and vertical.
1) Horizontal
The horizontal connector box looks like a flat or cylindrical housing. They provide space and protection for fiber optic cable connectors and connectors. They can be installed in antenna, buried or underground applications. Horizontal types are more common than vertical type (dome-type) closures.
Most horizontal fiber closures can accommodate hundreds of fiber connections. They are designed to be waterproof and dustproof. They can be used in temperatures from -40 ° C to 85 ° C and can withstand pressures up to 106 kpa. The boxes are usually made of high-strength building plastic.
2) Vertical type
Vertical fiber optic splice closures look like domes, so they are also known as dome types. They conform to the same specifications as the horizontal type. They are designed for buried applications.
