In order to meet the stringent protection requirements of fiber optic connectors, fiber splice boxes are commonly used to provide space for fiber optic cables to be spliced together. Fiber optic connectors securely connect and store fiber, whether in outdoor plants or indoor buildings. It provides protection for fiber optic connectors and fiber optic cables because of their superior mechanical strength and rugged enclosure to ensure that connectors are not damaged by harsh environments.
First, the main features of the fiber connector box
The fiber optic splice closure is made of special industrial grade high strength plastic with a reliable moisture barrier. They are also optimized to withstand material aging due to natural environmental factors such as UV light.
Second, according to physical appearance, the types of Fiber Closure include horizontal and vertical.
Horizontal fiber optic closures are like flat or cylindrical enclosures. It typically contains one or more fiber splice trays that provide space and protection for fiber splices. Fiber splice trays for different fiber splice closures can have different designs and fiber counts. The figure below shows a 96 fiber horizontal fiber splice closure. It has two input ports and two output ports to provide space for 96 fiber connectors. There are four standard 24-fiber splice trays in the fiber splice closure.
The horizontal fiber splice closure is designed to be waterproof and dustproof. They have good adaptability and pressure resistance because they are usually made of high strength structural plastics. Horizontal optical closures are more commonly used than vertical fiber closures.
2. Vertical type
Vertical fiber optic closures look like domes, so they are also known as dome fiber optic connectors. They meet the same specifications as the horizontal type and 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. The following shows a 24-fiber connector box with five inlets and up to 24 fiber connectors in two 12-fiber splice trays. Unlike the above, the internal fiber optic splice tray here is suitable for the vertical design of the fiber splice box.
