What is a fiber terminal box?

Fiber terminal box play a vital role in ensuring efficient and reliable fiber management in FTTH applications. By understanding the components, types, and differences between various fiber management devices, enterprises can make informed decisions when deploying and maintaining fiber optic networks.

What is a fiber optic terminal box?

Fiber optic termination box (FTB), also known as optical junction box (OTB). It is an important component of fiber-to-the-home (FTTH) applications.A typical fiber optic termination box consists of three main parts: fiber connector protection components, internal components, and housing. Its main function is to effectively manage and terminate fiber optic cables, connecting the cable core to the pigtail.The internal components are usually protected by an IP-rated housing made of rugged and impact-resistant materials. This ensures that the components are protected from damage during operation and placement.

How to choose a durable fiber optic terminal box?

When deploying fiber termination boxes outdoors for a long time, it is crucial to choose the right housing:

1.Dustproof; 2. Corrosion-resistant; 3. Easy to open; 4. Equipped with a locking mechanism to prevent unauthorized access.

Types of fiber optic terminal boxes

1..Wall-mounted fiber optic terminal box

The wall-mounted fiber optic terminal box is ideal for field installation of pre-connected cables, connectors, or pigtail field connections. It is used as a termination point for feeder cables that connect branch cables. It is suitable for entry terminals, computer rooms, telecommunication cabinets, and main cross-connections.

2.Rack-mounted fiber optic terminal box

The functions of the rack-mounted fiber optic terminal box include integrated fiber splicing, termination, distribution, storage, patching, and management. It is designed for cross-connection and interconnection topologies. Its pull-out design is easy to maintain.

3.Outdoor fiber optic terminal box

A highly durable housing used to distribute optical fibers in FTTX networks. It can be sealed to protect the cables from environmental damage. It is commonly used for fiber splicing, termination, and cable management in exterior wall installation applications.

4.Indoor Fiber Terminal Box

Serves as a transition point between riser and horizontal fiber optic cables. It provides storage space for extending and terminating optical fibers. It serves as a connection point for splicing optical fibers.

Difference between Fiber Terminal Box and Fiber Distribution Box

Fiber terminal box is a device placed at the end of horizontal optical cable. It leads the incoming cable to the fiber jumper through the coupler for quick connection. It is the closest terminal device (switching equipment or PC) connected to ONU. Fiber distribution box is an interface device for connecting feeder cable and distribution cable. It is commonly used in outdoor, corridor, and indoor environments. It is widely used in FTTH and FTTB fiber optic networks.
