Integrated fiber optic tray The maintenance and repair of optical cable is one of the key links of optical transmission system. With the continuous development of communication technology and the continuous improvement of users' requirements for network quality, how to improve the reliability and stability of line operation and ensure the safety and stability of equipment has become one of the key problems to be solved urgently. At the same time, due to the continuous emergence and development of various new technologies (such as: SDH, etc.) and new equipment used in modern telecommunications networks, traditional light connection methods are also facing greater challenges, so more advanced technologies must be adopted to meet the requirements of the new era.
At present, there are thousands of various kinds of long-distance telephone exchange offices that have been built and put into use in China, and the number of them ranks first in the world. Most of them use traditional twisted pair and coaxial cable for signal transmission.
These systems generally have the following deficiencies:
1 In the case of multiplexing, it is easy to produce cross crosstalk;
2 When the fault occurs, it is not easy to find;
3 maintenance difficulties;
4. Long construction period;
5. Large investment;
6. It is not conducive to protecting the environment and so on.
In order to adapt to the development and change of this situation, it is necessary to develop a new type of optical fiber welding tool - optical fiber fusion disk to replace the original single core or multiple bare fibers or metal wires as a new welding device.
1, the use and characteristics of optical fiber fusion disk:
(1) A special instrument used to weld one or more optical fiber ends into contact with each other. The product is suitable for installation, commissioning and maintenance management of any type of multi-mode and multi-frequency access network. (including indoor and outdoor type).
(2) With small size, light weight and other characteristics, easy to carry and use.
(3) It can easily weld the two ends of two or more optical fibers of different models and specifications together to form a new optical fiber link; (The connector boxes at both ends can also be used directly.)
(4) can be used for installation and disassembly of various types of pigtails,( 63427652,such as: jumper pigtails, fixed pigtails, movable and rotating tail structures);
(5) A section of optical fiber of any length can be cut into several sections for backup;
(6) The optical fiber terminal can be inserted/removed without cutting the original optical fiber. (Plug and play)
(7) Simple optical fiber detection operation: the temperature value of the measured optical fiber can be quickly and accurately measured through the built-in thermocouple temperature sensor.)
2. Working principle
The utility model relates to a process in which a pulsed laser beam with high power density emitted by a laser illuminates between two surfaces of the welded optical fiber, thereby causing local thermal expansion and deformation to reach a thermoplastic state, and then extruding the fiber to a specified shape and size with the help of a certain mechanical force.
