What are the common types of fiber optic connector closures, depending on their different characteristics and people's different needs, it is mainly divided into two types: horizontal and vertical. Then follow the DOME Fiber Closure manufacturer to learn about the advantages of these two types. 1. 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 cabinets are usually made of high-strength building plastics and are widely used in cable television, telecommunications, and fiber optic networks. 2. Vertical fiber optic splice closures look like domes, so they are also known as domed fiber splice closures. They conform to the same specifications as the horizontal type. They are designed for buried applications. Vertical fiber splice closures are made of high-quality engineering plastics with one inlet/outlet, two inlet/outlet, and three inlet/outlet types for different fiber core counts. Vertical fiber splice boxes are used in CATV, telecommunications and fiber optic networks.
