Optical cable terminal box and optical fiber distribution box

The optical cable terminal box is a box where both ends of the optical fiber network are prepared to directly divide jumpers to connect to optoelectronic equipment. The size of the terminal box can be determined according to the site conditions or the number of optical fiber cores used. So, do you know what the principle of optical cable termination is? What is the difference between optical cable terminal box and optical fiber distribution box?

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 inlet port has a plastic protective ring to reduce the friction between the optical cable and the shell and play a protective role. The outlet port is made of plastic material, which will not scratch the pigtail, and the small outlets are arranged in an orderly manner, which is convenient for installation and beautiful.

Internal structure of the terminal box: Optical cable fixing frame: 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 fusion splice tray is achieved.

Fiber splicing tray: used to fix and protect fiber splicing points and store redundant optical fibers.

The wiring logic of the optical cable terminal box: optical cable → (incoming port) inside the box → optical cable fixing frame → reinforcing core fixing clip (optical fiber) splice tray (pigtail) → outlet port.

Features of optical cable terminal box: 1. The fusion fiber tray adopts a superimposed structure, which is flexible in configuration. It can be removed and welded on the workbench, and the operation and maintenance are convenient and quick. 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.

Application range 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 is the difference between optical cable terminal box and optical fiber distribution box

1. Different in nature

The optical cable terminal box is an auxiliary device for terminal wiring in the optical fiber transmission communication network. It is suitable for direct and branch connection of indoor optical cables and protects the 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. The scope of application is different

Optical cable terminal box as the carrier of information transmission, with optical fiber hardware as the information transmission medium, has become an important pillar of modern communication. The optical fiber distribution box is used for the introduction, fixing and stripping protection of optical cables, fusion splicing and protection of optical fibers, storage of pigtails, storage and management of jumper fibers, fixed connection and cross-connection of optical fibers, etc.; at the same time, it can be used according to customer requirements 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 leading in the optical cable, leading out the distribution pigtail and fixing and protecting the optical cable, the distribution pigtail and the performance of 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 terminal wiring in the optical fiber transmission communication network, and are suitable for direct connection of indoor optical cables. Connect with the branch and protect the fiber optic connector.
