[0021] In an embodiment of the present utility model, the optical cable socket 71 is opened on the outer wall of the box body 1, an optical cable winding base 72 is fixedly installed on the bottom inner wall of the box body 1 close to the optical cable socket 71, an optical fiber fusion splicing tray 73 is fixedly installed on the inner wall of the box body 1, a photodetector 74 is fixedly installed on the inner wall of the optical fiber fusion splicing tray 73, a fiber winding post 75 is fixedly installed on the side wall of the optical fiber fusion splicing tray 73, an ODF fiber terminal 76 is fixedly installed on the outer wall of the box body 1, a board card holder 77 is fixedly installed on the inner wall of the box body 1, an MPO female head 78 is fixedly installed on the side wall of the board card holder 77, and an MPO male head 79 is fixedly installed on the side wall of the photodetector 74.

[0022] Furthermore, a number of small through holes are provided on the side surface of the box body 1 and on the inner wall of the side close to the fan 2 and the power interface 3, which cooperate with the operation of the fan 2 to ensure the ventilation conditions inside the box body 1, thereby facilitating the dissipation of heat inside the box body 1 and ensuring the normal operation of the device. At the same time, the indicator light 5, the optical fiber fusion splicing tray 73, the photodetector 74 and the board card holder 77 inside the box body 1 are all connected to the circuit of the power interface 3 to supply power to these electrical devices and ensure the power supply requirements of the device. In addition, a main control board card and a service board card are fixedly installed inside the board card holder 77. The MPO female head 78 is fixedly connected to the service board card, and the MPO female head 78 is adapted to and plugged into the MPO male head 79 to transmit the detection result of the photodetector 74 for the optical fiber to the service board card in the form of a signal. The service board card converts the optical and electrical signals, and then transmits the optical and electrical signals to the main control board card, and the optical fiber monitoring information is transmitted outward through the main control board card.

[0023] In addition, the network cable interface 4 and the WiFi antenna socket 6 are both connected to the main control board card for telecommunications to achieve signal transmission between the main control board card and the outside, thereby facilitating the user to monitor the operating status of the internal devices of the optical fiber terminal box. At the same time, the external optical cable extends into the inside of the box body 1 from the optical cable socket 71, and other fixing structures such as plastic buckles can be used to fix the optical cable on the optical cable socket 71. The part of the optical cable inside the box body 1 removes the outer skin to expose several optical fiber lines inside. Part of the optical fiber lines are wound around the optical cable winding seat 72. Specifically, multiple groups of winding columns are provided on the upper surface of the optical cable winding seat 72 to facilitate the fixing of the optical fiber lines and avoid the interference of external dragging on the connection stability of the optical fiber lines inside the box body 1. Furthermore, the number of fiber coiling posts 75 is set to four groups, and the four groups of fiber coiling posts 75 are arranged in pairs on the front and rear outer walls of the optical fiber fusion splicing tray 73 respectively. After the optical fiber lines are wound around the fiber coiling posts 75, they extend into the optical fiber fusion splicing tray 73 and are fused in pairs at specific positions. And a photodetector 74 is provided at the fusion position of the optical fibers to detect the light passing performance of the fused optical fibers and ensure that the fusion quality of the optical fibers meets the standard, thereby facilitating the subsequent stable signal transmission.

[0024] In the embodiment of the present utility model, the fiber coiling posts 75 on the lower side of the optical fiber fusion splicing tray 73 can be used for winding the fused optical fiber lines.

For example, they can view the light passing rate of each optical fiber and the transmission intensity of optoelectronic signals, etc. The computer setup access terminal realizes signal connection with the main control board through the network cable interface 4, while the APP access terminal achieves real-time interconnection with the cloud through the WiFi antenna externally connected to the WiFi antenna socket 6, facilitating users' access and viewing at any time.

[0026] In the present utility model, during use, an external optical cable is passed through the optical cable socket 71 and inserted into the interior of the box body 1. The outer skin of the part of the optical cable inside the box body 1 is removed, and then the optical fiber lines are separated one by one and operated individually. First, they are wound around the winding posts provided on the optical cable winding base 72, then wound around the fiber coiling post 75 once, and finally the ends of the optical fiber lines are extended into the optical fiber fusion tray 73 to fuse the ends of the optical fiber lines with the ends of another optical fiber line connected to the ODF optical fiber terminal 76, thereby realizing optical fiber splitting and providing network signal transmission for more devices. And because the photodetector 74 is arranged in the optical fiber fusion tray 73, it monitors the operating condition of the fused optical fiber in real time, and realizes docking through the MPO male head 79 provided on its side and the MPO female head 78 installed on the service board, transmitting the optical fiber operating condition to the service board in the form of a signal, and then the service board converts the signal into an optoelectronic signal and transmits it to the main control board, thus facilitating users to query through the computer setup access terminal by plugging in a network cable on the network cable interface 4 or query through the APP access terminal by plugging in a WiFi antenna on the WiFi antenna socket 6, for the convenience of people's use.

[0027] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field.
