Fiber Splice Closure - Horizontal and Vertical Types

Fiber PLC Splitter  is usually used with outdoor fiber optic cables, provides space for the outdoor fiber optic cables to be spliced together. The fiber splice closures and the fiber trays inside will protect the spliced fiber and the joint parts of the outdoor fiber cables. Generally, the fiber splice closures are dome type and horizontal types, with the horizontal fiber splice closure is used more often. The fiber splice closures are made from special industrial grade, high tension plastic with a reliable moisture barrier. They are also optimized to resist aging of the material due to factors in the natural environment such as ultraviolet light. There are two main types of closures, fiber optic and fiber optic terminal. A closure is a hardware used to restore integrity of fiber cables entering the enclosure. The terminal is a hardened external connector that allows the addition of one or more fiber cables to the enclosure. These two categories can be configured as butt closures and in-line closures. The butt closure allows cables to enter from one end, while the in-line allows entry from both ends. For outside plant splice closure, there are two major types: horizontal type and vertical type. Horizontal type: Horizontal type fiber splice closures look like flat or cylindrical case. They provide space and protection for optical 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 closure can accommodate hundreds of fiber connections. They are designed to be waterproof and dust proof. They can be used in temperature ranging from -40°C to 85°C and can accommodate up to 106 kpa pressure. The cases are usually made of high tensile construction plastic. And this type of fiber splice closure is widely used in CATV, telecommunications, and fiber optic networks. Vertical Type: Vertical type of fiber splice closures look like a dome, thus they are also called dome fiber splice closure. They meet the same specification as the horizontal types. They are designed for buried applications. Vertical fiber splice closures are made of excellent engineering plastics, they are with 1 inlet/outlet ports, 2 inlet/outlet ports, 3 inlet/outlet ports types, fitting different fiber optic core numbers. The vertical fiber splice closure is also used in CATV, telecommunications, and fiber optic networks.
