Fiber Optic Splice Closure Basics In order to meet the stringent protection requirements of fiber optic splices, Fiber Optic Splice Closure , also called fiber splicing closures, are usually used to provide space for fiber optic cables to be spliced together. The fiber optic closure connects and stores optical fibers safely either in the outside plant or indoor buildings. It can provide protection for the fiber joint and the fiber cables, since they have excellent mechanical strength and strong out shell, which ensures the joints not be damaged by the hostile environment. Fiber Optic Splice Closure Types Generally, the fiber optic splice closures are horizontal types and dome type (also called vertical type). Horizontal types are used more often than vertical type (dome type) closures. 1.Inline Closure Inline Closure looks like a flat or cylindrical box which provide space and protection for fiber optic cable splicing and joint. They can be mounted aerial, buried, or for underground applications. Most Inline Closure can fit hundreds of fiber connection. They are designed to be waterproof and dust proof. They can be used in temperature ranging from -40°C to 85°C, can accommodate 70 to 106 kph pressure and the case are usually made of high tensile construction plastic. 2.DOME Fiber Closure DOME Fiber Closure looks like a dome. This is why they are also called dome type. They meed the same specification as the Inline Closure. They are usually designed for buried applications. Conclusion Greentelftth supplies fiber optic splice closures with different ports types, fittings and fiber optic core numbers. Fiber splice tray, fiber distribution box and fiber optic enclosure are also offered in conjunction with the splice closures, promoting a safe and well-managed environment for fiber optic splices.
