Fiber closure is often used with outdoor fiber-optic cables to provide space for splicing of outdoor fiber-optic cables. The fiber optic closure and the internal fiber tray will protect the splice part of the spliced fiber and outdoor cable. Typically, the fiber optic connector closure is dome and horizontal, and the horizontal fiber connector is closed more frequently.
The fiber connector is made of a special industrial grade, high tension plastic, with a reliable moisture barrier. They are also optimized to resist the aging of materials due to factors in the natural environment such as ultraviolet light. The closure is the hardware used to restore the integrity of the fiber optic cable entering the housing. The terminal is a hardened external connector that allows the addition of one or more cables to the housing. In addition, it can be configured for docking off and online off. Docking off allows the cable to enter from one end, while the line is allowed to enter from both ends.
Horizontal fiber closures look like flat or cylindrical housings. They provide space and protection for fiber splicing and splicing. They can be installed in antennas, buried or underground applications. Horizontal type is more closed than vertical type (dome). Most horizontal fiber shutters can accommodate hundreds of fiber connections. Their design is waterproof and dustproof. They can be used in the -40 ° C to 85 ° C temperature range, can withstand up to 106 kPa pressure. These are usually made of high-strength building plastics and are widely used in cable television, telecommunications and fiber-optic networks.
The vertical fiber closures look like a dome, so they are also called dome optical fiber connectors closed. They conform to the same specifications as the horizontal type. They are designed for buried applications. Vertical fiber optic connectors are closed for CATV, telecommunications and fiber optic networks. The fiber connector seals the ribbon cable and the round fiber optic cable. Each type (ribbon or round cable) is suitable for a variety of fiber splicing counting requirements. Fiber closure are widely used in optical communication systems.
