Internal structure of optical fiber electrical box

The internal structure of a fiber optic electrical box (commonly referred to as a fiber distribution box or ODF box) is usually designed to be both compact and efficient for the management and maintenance of the fiber. The following is a detailed overview of the internal structure of the optical fiber electrical box:

First, box structure

Material: The optical fiber electric box box is mostly made of cold-rolled plate (such as Q235-A), and the surface is treated by epoxy electrostatic spray, which has the characteristics of corrosion resistance and aging resistance. Some high-end products may be made of stainless steel to enhance corrosion resistance and aesthetics.

Sealing performance: The sealing performance of the box is good, and the protection level is usually IP65 or above, which can resist the harsh outdoor environment, such as rain, dust and so on.

Door opening mode: The box can be front door or front door opening design, easy to install and maintain. Some products also use anti-theft door locks to increase security.

Second, internal structure layout

Modular design: The interior of the optical fiber electrical box adopts modular design, reasonable layout, multiple functions and high density. This design makes the layout, connection and management of optical fibers more flexible and efficient.

Main components:

- Fiber welding area: Used for welding optical fibers and pigtails. This area is usually equipped with welding disc, welding machine and other equipment to ensure the quality of welding.

- Distribution area: The distribution area is equipped with a distribution disk and an adapter panel for the cross-connection or direct connection of optical fibers. Various types of optical fiber connectors, such as SC, LC, and ST, can be installed on the adapter panel.

- Fixing device: The optical fibers and pigtails are fixed in the box by fixing devices to prevent loosening or falling off. These fixtures may include fixtures, bindings, etc.

- Identification system: To facilitate management and maintenance, the optical fiber electrical box is usually equipped with a identification system, which is used to identify the starting direction, number of cores, and color of each optical fiber.

Third, functional area division

External cable lead-in area: Used to introduce external optical cables, and equipped with waterproof mud and other sealing materials to ensure the tightness of optical cable lead-in holes.

Direct fusion zone: It is directly used for the welding operation of optical cable, reducing the use of optical fiber jumper and reducing costs.

External area (trunk and distribution) : used for the connection and management of trunk optical cable and distribution optical cable. This area may be equipped with equipment such as integrated pallets for welding and laying of optical cables.

Optical splitter area: used to install optical splitter to achieve optical signal distribution and transmission. The optical splitter area is usually designed with sufficient space to install and maintain the optical splitter.

Idle pigtails Management center: Used to store and manage unused pigtails to ensure that the pigtails are clean and orderly.

Fourth, special design

Flip plate structure: Some fiber optic electrical boxes use flip plate structure design, making it possible to configure high-density ports and splitter facilities. This design not only saves space, but also increases the flexibility of fiber management.

Flame retardant materials: In order to enhance safety, the plastic parts inside the optical fiber electrical box are mostly made of flame retardant materials, such as flame retardant ABS material parts.

Grounding system: The optical fiber electric box is equipped with a good grounding system, including two layers of protection ground and rack ground, to ensure the safe operation of the equipment in harsh environments such as lightning.

In summary, the internal structure of the optical fiber electrical box is compact, reasonable layout and complete functions, which can meet the efficient management and maintenance requirements of optical fiber networks. At the same time, with the continuous progress of technology and the increase of application demand, the internal structure of the optical fiber electrical box is also constantly optimized and upgraded.
