Fiber distribution box with its own advantages has been widely used in various cabling projects. It is also known as the FD-A application field, which refers to an access point of optical fiber cable. It is an important component that provides power, connection and storage for optical fiber cables. The most widely used in the field are FDX-A or FD-A fiber distribution Boxes.

The main functions of FDX-A or FD-A fiber distribution box are as follows:

• Provide power for optical fiber cables, reduce link loss, and ensure the quality of optical cables.
• Provide channels for connecting optical fiber cables, priority link, and passive optical networks (PON).
• Provide a storage area for existing optical fibre cables.

The working principle of FDX-A or FD-A fiber distribution box is similar to that of other fiber distribution boxes. In the FDX-A or FD-A fiber distribution box, there are usually several fiber adapters mounted on the box to connect incoming and outgoing cables. The fiber adapter is composed of several optical fiber terminals. The incoming cable enters the box and is connected to the fiber adapter. The cables passing through the box will be connected to the fiber adapter. Then, the cables will be lead out through the connectors on the fiber adapter.

In some cases, the fiber adapter may include an optical splitter to divide the power between incoming and outgoing cables. In this way, the power of the light source is evenly divided between the incoming and outgoing cables. The fiber adapter also includes a WDM (wavelength division multiplexer) or a DCM (dichroic mirror) to isolate the light source from the fiber.

The FDX-A or FD-A fiber distribution box can also be used to connect the optical cable to the network interface equipment. This connection is typically done through a bidirectional optical adapter. This bidirectional optical adapter is divided into two parts. One part is connected to the main fiber cable,while the other part is connected to the network equipment.

The FDX-A or FD-A fiber distribution box is an important component in optical fiber network. It helps to provide power and connection for optical fiber cables, and can be used to connect the optical cable to the network interface equipment. In addition, it can provide a storage area for existing optical cables. With its own advantages, the FDX-A or FD-A fiber distribution box has been widely used in various cabling projects, thus making it an indispensable component in optical fiber network.
