What are Fiber Optic Termination Boxes?

As we all know, outside the basic communication engineering equipment, operators frequently deal with a variety of optical fiber goods of various types and sizes. In fact, basic communication optical fiber projects, in addition to our normal optical fiber products, are essential for connecting equipment. What kind of devices are fiber optic termination boxes? Let’s take a look at the article below.

What are Fiber Optic Termination Boxes?

When we open a landline phone or broadband network, the installer from operators will pull a line from a small box installed on the wall in the public area of the community, and then connect it to your home. This small box is a fiber termination box. In simple words, the fiber optic termination box is the rear connector of an optical cable. It is an end point of the optical cable extending to the user’s home. This end point is also called the pigtail. For users, fiber optic termination boxes are devices that split a fiber optic cable into several single fibers.

Types of Termination Boxes

Wall Mount Termination Boxes

Wall mount fiber optic termination boxes are intended for field installation of pre-connected cables, connectors, or pigtail field connection. In a FTTx network infrastructure, it serves as a termination point for the feeder cable that connects to the drop cable. They are an excellent choice for entry terminals, computer rooms, telecommunication cabinets, primary cross-connects, and other controlled applications.Wall Mount Termination Boxes

Rack Mount Termination Boxes

Rack mount fiber optic termination boxes integrate fiber splicing, termination, distribution, storage, patching and management. Interfaces between external equipment cables and transmission equipment are designed for cross-connect and interconnect topologies. The benefit of this type of termination box is that it is easy to maintain, as you can pull out to check at all times and it’s very convenient.

Outdoor Termination Boxes

Outdoor fiber termination box is a highly durable enclosure, used to distribute fiber for FTTX networks. People use outside wall mount fiber optic termination boxes for fiber splicing, termination, and cable management. On the other hand, termination boxes are normally sealed to protect the cable from environmental damage caused by FTTH networks.

Indoor Termination Boxes

Indoor fiber termination box for fiber serves as a transition point between risers and horizontal fiber optic cables, providing operators with optimum flexibility. People use it as a storage location for extending and terminating fibers, or as a connection point for splicing fibers. In addition, indoor fiber termination box provides space for ultra-long terminated fibers and fiber convergence.


  • High quality engineering plastic with good strength
  • With safe special-shaped lock, the box can open easily and has good water-proof performance, suitable for indoor and outdoor natural environments
  • Independent rubber sealing plug for drop cable, better waterproof performance
  • Double-page design, the box can be installed and maintained easily, the fusion and termination are completely separated


People use fiber optic terminal boxes mostly in optical communications networks such as telephone, data, CATV cable television series, and image transmission systems. Also optical fiber terminal box is used in distributing and connecting various optical fiber systems, particularly the distribution of the micro-grid terminal that connects the optical cable and the jumper core.

Lomoveishiy – Finland

I needed those to connect my PC on the third floor to have internet access in that room, and ISP installed their modem on the first floor only. After dropping fiber patch cables, plugged in all cables into these media converters at both sides, and link came up instantly. Was much easier than I thought!

Raymond – USA

Great experience – units worked straight out of the box – just needed plug in cables and we were done. I also like the possibility to enable jumbo frames, while we do not have a need for this feature at the current moment it’s great to have this option.
