The internal structure of the optical cable split fiber box

An optical cable split fiber box, also known as a fiber distribution box or fiber optic splice closure, is a device used to terminate, splice, and distribute optical fibers. It typically consists of two parts: an outer housing and an internal structure. In this response, we will focus on the internal structure of the optical cable split fiber box.

Splice Tray: The splice tray is the heart of the fiber distribution box, and its function is to hold the optical fiber splices. The tray is usually made of plastic or metal and can hold a varying number of fibers, depending on the size of the box. The tray has a series of grooves or channels where the optical fibers are placed and secured using splice sleeves.

Fiber Management System: The fiber management system is designed to protect the fibers from any external forces that could damage them. It also helps to manage the excess fiber slack and keep the fibers organized. The fiber management system may include spooling devices, fiber routing guides, and tie-downs.

Cable Entries: Cable entries are ports on the fiber distribution box where optical fibers are routed into the box. They may be sealed with rubber grommets or other types of cable seals to provide environmental protection and to prevent the ingress of moisture, dust, or other contaminants.

Splitter Modules: Splitter modules are used to divide the optical signal into multiple fibers, allowing it to be distributed to multiple locations. The splitter module may be integrated into the fiber distribution box or may be a separate component that is installed within the box.

Connector Panels: Connector panels provide a connection point for optical connectors to terminate the optical fibers. They may be located on the sides or the top of the fiber distribution box and may be removable or fixed in place.

Sealant and Gaskets: Sealant and gaskets are used to protect the optical fibers from the environment and to ensure that the box is water-tight. They may be made of rubber, silicone, or other materials, and they are applied to the joints and seams of the box to prevent moisture or other contaminants from entering.

Mounting Bracket: A mounting bracket is used to secure the fiber distribution box to a wall, pole, or other structure. It may be made of metal or plastic and is designed to provide a secure and stable mounting platform for the box.

In conclusion, the internal structure of an optical cable split fiber box is designed to protect and manage the optical fibers and to facilitate the connection and distribution of the optical signal. The specific components of the fiber distribution box may vary depending on the size and application of the box, but they all serve the same basic functions.
