We all know that the optical cable terminal box is a box at both ends of the optical fiber network that is ready to be directly connected to the optoelectronic equipment. So, do you know what the principle of optical cable termination is? What are the differences between optical cable terminal boxes and optical fiber distribution boxes?

 

What is the principle of optical cable terminal box

The optical cable terminal box is divided into: engineering plastic ABS material and high-quality cold-rolled steel plate; the incoming port has a plastic protective ring, which reduces the friction between the optical cable and the outer casing and plays a protective role. The outlet port is made of plastic material, which will not scratch the pigtail. The small outlets are arranged in an orderly manner, which is convenient for installation and beautiful.

 

The internal structure of the terminal box: optical cable fixing frame: to fix the optical cable entering the optical cable terminal box.

 

Strengthening core fixing clip: By fixing the strengthening core of the optical cable, the purpose of fixing the optical fiber cable connected to the splice tray is achieved.

 

Splice tray: used to fix and protect optical fiber splice points and store redundant optical fibers.

 

Optical cable terminal box wiring logic: optical cable → (incoming port) inside the box → optical cable fixing frame → reinforcing core fixing clip (optical fiber) splicing fiber tray (pigtail) → outgoing port.

Features of the optical cable terminal box: 1. The fiber splice tray adopts a superimposed structure with flexible configuration. It can be removed to the workbench for fusion splicing, and the operation and maintenance are convenient and fast. 2. There are various types of products, including pigtail type, adapter type and cabinet type optical cable terminal box, which can be customized according to needs.

 

Scope of application of optical cable terminal box: Optical cable terminal box is widely used in local telephone, rural telephone network system, data, image transmission system, CAYV cable TV series.

 

What are the differences between optical cable terminal boxes and optical fiber distribution boxes

1. Different in nature

Optical cable terminal box is an auxiliary equipment for terminal wiring in optical fiber transmission communication network. It is suitable for direct and branch connection of indoor optical cable, and protects optical fiber joints. The optical fiber distribution box is suitable for the wiring connection between the optical cable and the optical communication equipment. Through the adapter in the distribution box, the optical signal is drawn out with the optical jumper to realize the optical wiring function.

 

2. Different scope of application

As the carrier of information transmission, the optical cable terminal box has become an important pillar of modern communication with optical fiber hardware as the information transmission medium. The optical fiber distribution box is used for the introduction, fixing and stripping protection of optical cables, splicing and protection of optical fibers, storage of pigtails, storage and management of jumpers, fixed connection and cross-connection of optical fibers, etc. Install value-added module units such as optical splitters and wavelength division multiplexers.

 

3. Different characteristics

The optical cable terminal box has the functions of introducing the optical cable, pulling out the distribution pigtail, and fixing and protecting the optical cable, the distribution pigtail and the optical fiber in it from damage. The optical fiber distribution box is suitable for the protective connection of optical cables and distribution pigtails, and is also suitable for the use of optical fiber termination points in the optical fiber access network.

 

The above is the whole content of the principle of the optical cable terminal box and the difference between the optical cable terminal box and the optical fiber distribution box. In fact, the optical cable terminal box series products are auxiliary equipment for the terminal wiring in the optical fiber transmission communication network. It is connected to the branch and protects the fiber optic connector.
