Fiber Termination Box Overview

What Is Fiber Termination Box?

Fiber termination box or fiber optic terminal box, which generally refers to a box shape cable management product used to protect and distribute the optical fiber links. It is small size and compact, used in FTTX cabling, including fiber cabling and cable management. Fiber termination box can be regarded as the mini size of fiber optic patch panel and ODF.

Types Of Fiber Termination Box

Usually the fiber termination boxes include fiber optic patch panel and fiber terminal box. Fiber optic patch panel is bigger size, while fiber terminal box is smaller. However, there are too many fiber optic termination boxes and cable management devices that it is hard to count their types. Many manufacturers will make the fiber optic termination boxes according to their own design and give the fiber optic termination boxes different names and model numbers.

Fiber Optic Patch Panels are usually 19 inch size. They can be wall mounted type or rack mounted type, and they have the tray inside the fiber box to hold and protect the fiber links. They can be pre-installed with various kinds of fiber optic adapters, which are the interface via that the fiber box will connect the external devices.

Fiber Optic Terminal Boxes are also used for fiber optic distribution and organization. Typical fiber terminal boxes are with 12 ports or 24 ports, with a size of 270mm*137mm*45mm. However, FiberStore can offer 8 ports, 36 ports, 48 ports and 96 ports fiber terminal boxes. They are made of cold rolling steel and the surface of the boxes use the technique of dim blowing plastic. They are typically installed with FC or ST adapters on the panel on the wall or put in horizontal line.

Fiber termination box types are mainly described as Rack Mount and Wall Mount:

Rack Mount Fiber Termination Box

The rack mount slide-out type fiber termination box performs fiber splicing, distribution, termination, patching, storage and management in one unit. They support both cross-connect and interconnect architecture, and provide interfaces between outside plant cables and transmission equipment.

Wall Mount Fiber Termination Box

The wall mount fiber termination boxes are designed for either preconnectorized cables, field installation of connectors, or field splicing of pigtails. They are ideal for building entrance terminals, telecommunication closets, main crossconnects, computer rooms and other controlled environments.

Fiber termination box types also include indoor and outdoor:

Indoor Fiber Termination Box

For example, FTTH floor terminal box is specifically designed to be installed on each level of a multi-dwelling unit (MDU) building for fiber to the home applications. It is the transition point between the riser and the horizontal cable and provides operators with optimum flexibility. It provides storage for both overlength and terminated fibers as well as serving as a splice point.

Outdoor Fiber Termination Box

The outdoor fiber terminal boxes are environmentally sealed enclosures to distribution fibers for FTTX networks. They are also designed for fiber splicing, termination, and cable management.

Structure Of Fiber Termination Box

Fiber termination box consists of the shell, the internals (supporting frame, set fiber disc, fixing device) and optical fiber joint protective element. It has advantages of cable-fixing, welding, and play protection role in machinery of the optical fiber and its components ,and environment.

Fiber termination box requires a insulation between cable metal components and cable terminal box shell, and can be easily drawn out of ground. It is able to provide a place of cable terminal and a room to storage the remaining fiber, easy to install, and having a sufficient impact strength box to be fixed, that facilitate the installation of different occasions. If necessary, it should have a function of connecting cable branching.

Applications Of Fiber Termination Box

Fiber termination box is suitable for fixing the end of fiber and splicing the fiber pigtail, meantime it protects fiber splice tie-in and helps to distribute fiber. Termination box is mainly used in telecom equipment room or network equipment room.

Fiber termination box is available for the distribution and termination connection for various kinds of fiber optic systems, especially suitable for mini-network terminal distribution, in which the optical cables, patch cores or pigtails are connected.
