Speaking of a knowledge of optical cable, then I want to say that I can't finish it in the last few days and nights. For example, the optical cable splice box that I want to talk about today. So, what is a fiber optic splice box? What are the internal structures of the optical cable splice box?
What is a fiber optic splice box
Optical cable splice box is a popular name, scientific name is optical cable splice box, also known as optical cable splice package, optical cable splice package and barrel. It belongs to the mechanical pressure sealing joint system and is a splicing protection device that provides continuity of optical, sealing and mechanical strength between adjacent optical cables. It is mainly used for straight-through and branch connections of overhead, pipeline, direct burial and other laying methods of optical cables of various structures.
Optical cable splice box is a connection part that connects two or more optical cables together and has protective parts. It is a must in the construction of optical cable line engineering, and it is one of the very important equipment. The quality of optical cable joint box directly affects the optical cable. The quality of the line and the service life of the optical cable line.
According to the connection method of optical cable, it can be divided into straight-through type and branch type. According to whether the adapter can be assembled, it can be divided into the adaptable type and the non-mountable type. According to the shell material, it can be divided into plastic shell and metal shell.
What are the internal structures of the optical cable splice box
1. Support frame: It is the main body of the internal components.
2. Optical cable fixing device: used for fixing the optical cable and the base and fixing the optical cable strengthening element. One is the internal fixation of the reinforcing core of the optical cable; the second is the clamping and fixing of the optical cable and the support frame; the third is that the optical cable and the inlet and outlet cables of the splice box are sealed and fixed with a heat shrinkable sheath.
3. Optical fiber placement device: It can store optical fiber connectors and remaining optical fibers in order. The length of the remaining optical fibers should not be less than 1 meter, and the labyrinth of the remaining optical fibers should not be less than 35mm. Among them, the storage tray can have up to four layers, the capacity is large, and the storage tray can be adjusted according to the number of cores connected by the optical cable.
4. Optical fiber connector protection: Putting the heat-shrinked protective sleeve on the fiber core fixing clip in the receiving tray can also use the silica gel fixing method.
5. Sealing the optical cable and the splice box: Use abrasive cloth to polish the junction of the splice box and the optical cable at the cable entry point of the base, clean the polished area with detergent, paste it with aluminum foil, and then put the heat shrinkable tube on the splice box. At the cable entry point, use a blowtorch to heat slowly from the middle to the two ends, so that the entire heat shrinkable tube can be completely shrunk.
The above is what is the optical cable splice box and what the internal structure of the optical cable splice box is. In fact, the optical cable splice box is suitable for the straight-through and branch connection of various structures of optical cables such as overhead, pipeline, direct burial and other laying methods. The optical cable splice box is also suitable for the connection in the terminal room of the structured optical cable.
