[0002] Fiber optic communication, also known as optical fiber communication, refers to the use of light and optical fibers to transmit information and is a type of wired communication. Light can carry information after being modulated. Modern fiber optic communication systems mostly include a transmitter that converts electrical signals into optical signals, which are then transmitted through optical fibers. The optical fibers are mostly buried underground and connect different buildings. The system also includes several optical amplifiers and an optical receiver to convert optical signals back into electrical signals. Most of the signals transmitted in fiber optic communication systems are digital signals, and the sources include computers, telephone systems, or cable TV systems.

The fiber optic hub includes a hub, an optical fiber, and a connector. The hub is fixed inside the drawer-type tray, and the optical fiber is wound around the hub. Connectors are provided at both ends of the optical fiber, wherein the connectors are connected to the fiber optic adapter. The utility model facilitates the pulling out and putting in of the drawer-type tray through the slide rail, facilitating the installation of the optical fiber, while also protecting the internal fiber optic hub. The optical fibers on the fiber optic hub can be connected through the fiber optic adapter to form fiber optic links of different lengths, ensuring a variety of product combination lengths, quick connection, simple operation, and safety and reliability.

[0004] However, the axle of this patent is fixedly connected to the inside of the tray, and the length of the optical fiber wound on the axle is fixed, and the axle cannot be replaced, resulting in limited experimental data for the metropolitan area network and a small scope of application of the distribution box. Based on this, a distribution box that facilitates rapid combination of optical fiber lengths is proposed. Utility Model Content

[0021] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, a distribution box for quickly assembling optical fiber lengths includes a box body 1, a box cover 2, an observation window 3, and an adapter 4. A guide plate 5 is fixedly connected to the inner bottom of the box body 1. The setting of the guide plate 5 can prevent the optical fiber 13 wound on the line roller 12 from becoming loose. The top of the guide plate 5 is fixedly connected to a sliding bin 9. A slider 15 is slidably connected to the sliding bin 9. The slider 15 can slide up and down in the sliding bin 9 but cannot slide out of the sliding bin 9. A fixing column 10 is installed on the slider 15 through a fixing component, and a ring 1 is installed on the fixing column 10 through a positioning component. 1, a wire roller 12 is rotatably connected to the ring 11, an optical fiber 13 is wound on the wire roller 12, the free ends of the optical fibers 13 are fixedly connected to wiring terminals 14, the wiring terminals 14 are adapted to the adapter 4, a wiring block 6 is fixedly connected to the top middle of the guide plate 5, wiring ports 7 and output ports 8 are provided on both sides of the wiring block 6, the wiring ports 7 and output ports 8 are adapted to the wiring terminals 14, the box cover 2 is mounted on the box body 1 through a hinge, the observation window 3 is mounted on the box cover 2, the adapter 4 is mounted on the box body 1, and the slide 9 is fixedly connected to the inner wall of the box body 1.

[0022] When in use, open the box cover 2 and, according to the length requirement of the optical fiber 13 of the metropolitan area network, first connect the terminal block 14 to the adapter 4, and then insert the terminal block 14 into the wiring port 7 to interconnect the optical fibers 13 in the box body 1, or directly insert the terminal block 14 into the output port 8 for direct output, thereby realizing free combination of the length of the optical fiber 13 and expanding the experimental range. In addition, through the setting of the fixing component and the positioning component, the line roller 12 of different sizes can be replaced, thereby replacing the optical fiber 13 of different lengths. The operation is simple and quick, making the metropolitan area network data obtained through the distribution box more comprehensive.

[0023] like Figure 2 、 Figure 3 and Figure 4 As shown, the fixing assembly includes a slide groove 16 opened at both ends of the fixing column 10, and a dial plate 17 is slidably connected in the slide groove 16. A fixing rod 18 and a fixing spring 20 are respectively fixedly connected on both sides of the dial plate 17. A fixing hole 19 is opened on the side of the slider 15 close to the fixing column 10. The fixing rod 18 is adapted to the fixing hole 19. The fixing spring 20 is fixedly connected in the slide groove 16. The fixing rod 18 is slidably connected in the slide groove 16.

The two ends of the positioning spring 24 are respectively fixedly connected to the positioning column 22 and the groove 21.

[0024] When replacing the line roller 12 of different sizes, first manually buckle the dial plate 17 so that the dial plate 17 drives the fixing rod 18 to slide into the slide groove 16 to compress the fixing spring 20, so that the fixing rod 18 is pulled out of the fixing hole 19, and the fixing column 10 can be removed from the slider 15. Then, pull the pull rod 25 upward to pull the positioning column 22 out of the positioning hole 23, and then the ring 11 can be removed from the fixing column 10, and then the line roller 12 can be removed. When installing again, first pull the pull rod 25 upward to make the end of the positioning column 22 flush with the inner wall of the ring 11, and then align the side of the ring 11 with the positioning column 22 installed with the side of the fixing column 10 with the positioning hole 23. , the collar 11 can be put on the fixing post 10 and moved until the positioning post 22 can enter the positioning hole 23 under the action of the positioning spring 24, and then the slider 15 is slid so that the slider 15 reaches the top of the slide 9. At this time, the dial plate 17 can be manually buckled so that the dial plate 17 drives the fixing rod 18 to slide into the slide groove 16 to compress the fixing spring 20. Then the fixing post 10 is placed between the sliders 15 so that the fixing rod 18 is aligned with the fixing hole 19, and the dial plate 17 can be released so that the fixing rod 18 enters the fixing hole 19 under the action of the fixing spring 20. The installation is completed, and then the fixing post 10 is pushed downward so that the collar 11 fits on the guide plate 5;

[0025] The operation is simple and quick, so that the distribution box can combine optical fibers 13 of different lengths, thereby making the metropolitan area network data obtained through the distribution box more convincing, ensuring that the obtained data is more comprehensive and easy to use.

[0026] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
