Fully introduction of Bwinners fiber optic distribution box

The fiber distribution box comes with splice trays and cable management for splitting incoming and outgoing cables. Made to fit a wide range of installer needs, the enclosure features exposed front and rear panels in order to allow for easy access to all areas inside.

It can splice multiple cable transmissions in one box with just minimum number of splice trays. And it also comes with combining splice trays for keeping the cables split into outgoing and incoming flows.


There are two types of fiber optic distribution box, one is wall-mounted fiber optic distribution box which is used on wall and the other is Pole mounted fiber optic distribution box.


The optical fiber cable distribution box can be made of plastic, metal or SMC All of these three material fiber optical distribution box can be found from Bwinners. You can choose the suitable one according to your requirement. Bwinners will show the material as below.

– Plastic

Normally the plastic fiber distribution box materials used are PP, ABS, ABS+PC. The differences between those materials are in the density to obtain more impact resistance, temperature and flame resistance.

ABS is also cheaper than PC and is the most used for regular environments.

ABS+PC Strong material to endure harsh environmental conditions.

PC+ABS material used ensures the body strong and light.

– Metal

This metal fiber optic distribution box comes with a durable metal construction to provide additional strength and reliability.

The metal material that is used to make the box is strong for outdoor uses, and waterproof for enhanced durability.


SMC (Glass fiber reinforced plastic) Fiber Distribution Box is lighter than the metal material box but stronger than the plastic material box, and can be molded to be different beautiful shapes. For Indoor/Outdoor application.

If you don’t sure what material is suitable for your network project, just feel free to contact us, we’d like to provide you the best solution.

Why Distribution Box

  • Simplify the cable management:

With fiber distribution boxes, you can expect cables to be organized without having to deal with difficult cable management issues. Simplified installation and maintenance with movable structure.

  • Pre-installed splice tray:

You don’t have to worry about having problems with the internal connections because it comes with a pre-installed splice tray.

  • Available to add extra protection:

The fiber optic box is designed to accommodate multiple fusion splice trays and splice protection sleeves. You have the option of adding on other accessories and security features so that you are able to add extra protection whenever necessary.

  • Easy installation:

The fiber optic box is designed for easy installation which means that you can finish setting up the equipment and have everything installed in a short period of time.

  • Multi-functions in one box:

The fiber optic distribution box is used in the wiring, splicing, distribution, and terminal connection of optical fiber cable. Inside with tray for splicing and easily accessible main cables. Cable connection and splicing can be carried out in the same box.


The structure of the optical fiber distribution box is mainly composed of the box body, the internal sheet metal workpiece, the optical fiber movable connector, and the spare accessories.

The structure of the fiber optic distribution box is composed of several functional units. The functional units are :

  1. Making the SC or LC fiber adapter,
  2. Connecting with optical patch cord or fiber pigtail,
  3. Connecting with mechanical patch cord,
  4. Connecting with optical drop cable or communication line


  1. Provide fixing space for optical fiber or other devices, suitable for fiber to the home (FTTH) applications;
  2. Network interconnection
  3. Resource sharing can provide users with various services such as voice, data, radio and television
  4. Fiber To The Cabinet (FTTC)
  5. Fiber To The Building (FTTB)
  6. CATV networks
  7. Optical fiber communication
