[0002] Optical fiber transmission refers to the transmission of data and signals using optical fiber as the medium. Optical fiber can not only be used to transmit analog and digital signals, but also meet the needs of video transmission. The transmission methods of optical fiber transmission equipment can be simply divided into: multi-mode optical fiber transmission equipment and single-mode optical fiber transmission equipment. The data transmission rate of a single optical fiber can reach several Gbps, and the transmission range can reach 6-8km. Among them, a repeater is a type of optical fiber transmission device. The transmission distance of network interconnection can be further extended through a repeater. The repeater has the function of amplifying and regenerating the signal on the line, and is widely used to extend the length of the LAN segment.

[0003] Traditional optical fiber transmission devices generally use a single crystal head to insert the interface device in the network connection in a fixed direction and automatically prevent it from falling off the connection. Each time the interface device is replaced or maintained, each optical fiber with a crystal head needs to be plugged in and out one by one. The installation and disassembly operations are time-consuming and labor-intensive, and the efficiency is low, resulting in inconvenience in use.

The second embodiment of the present invention can also be directly applied to the existing optical fiber equipment body 01 in the existing market (the first plug-in unit 02 is directly arranged on the optical fiber equipment body 01, without the first contact terminal 2 and the second contact terminal 4 and other structures).

[0040] Embodiment 4, on the basis of embodiment 2 or embodiment 3, a winding device 17 is provided on the flexible wire harness 14, and the winding device 17 is used to selectively wind up the flexible wire harness 14, such as Figure 8 As shown, the winding device 17 facilitates the selective stretching or winding of the flexible harness 14, thereby preventing the flexible harness 14 from becoming messy or too short during installation, disassembly and maintenance of the optical fiber transmission device, resulting in inconvenient installation and a long maintenance cycle.

[0041] Embodiment 5, based on embodiment 4, the number of winding devices 17 is not less than two, such as Fig. 9 As shown, the use of multiple winding devices 17 can further relatively extend the telescopic range of the flexible wire harness 14 in different sections, achieving the technical effects of simple and convenient installation and disassembly, saving operation time and improving maintenance efficiency.

The fixing frame 131 is provided with a guide hole 134 connected to the slot 133. A pressing rod 135 is provided in the guide hole 134. The pressing rod 135 is used to selectively press the elastic buckle 132 out of the slot 133, as shown in FIG. Fig.10 As shown; by relatively pressing the second mounting plate 6 and / or the third mounting plate 9 into the fixing frame 131, the elastic buckle 132 undergoes elastic deformation during the pressing process and finally engages with the card slot 133 on the fixing frame 131, so as to ensure quick installation or removal of multiple sets of wiring harnesses at one time while improving the connection stability and safety performance between the third contact terminal 7 and the fourth contact terminal 10, avoiding the occurrence of safety incidents or poor communication quality caused by arcing due to poor connection stability between the third contact terminal 7 and the fourth contact terminal 10. When disassembly is required, just press the The pressing rod 135 contacts the elastic buckle 132 and presses the elastic buckle 132 out of the slot 133, so that the fixing frame 131 and the second mounting plate 6 and / or the third mounting plate 9 can be quickly disassembled and assembled, thereby achieving the technical effects of simple and convenient installation and disassembly, saving operation time and improving maintenance efficiency. It should be noted that the second locking assembly 13 in the present technical solution is used in conjunction with the above-mentioned fixing frame 131, elastic buckle 132, slot 133, guide hole 134 and pressing rod 135, and a screw locking structure or a buckle locking structure can also be used.
