[0002] When optical signals are transmitted in optical fibers, they will attenuate as the distance increases. Especially in the range of 1-10 km, the signal strength may be reduced to a level that cannot be directly interpreted. Therefore, an optoelectronic conversion module is required to convert the optical signal into an electrical signal so that it can be processed and amplified at both ends of the delay line to ensure that the signal can be effectively transmitted and received. In addition, by properly winding the line during use, the optical fiber can be effectively protected from external physical damage (such as squeezing, pulling or bending) to ensure the physical integrity and long-term stability of the optical fiber.
[0003] The traditional 1-10km continuously adjustable electrically controlled optical fiber delay line with photoelectric conversion module usually drives the optical fiber disc to rotate by a motor when winding, and can indeed gradually retract the optical fiber delay line from its original position. In addition, the speed and tension of the motor can be controlled during the winding process to ensure the uniformity and stability of the winding.
[0004] The traditional 1-10km continuously adjustable electrically controlled optical fiber delay line with photoelectric conversion module has the following problems: since the take-up is directly controlled by the motor, it may be difficult to accurately control the tension distribution of the optical fiber delay line, which affects the neat arrangement of the optical fiber on the reel, and is prone to stacking and cross-winding, resulting in uneven distribution on the optical fiber reel, which may affect subsequent use and maintenance.

After the line is released, the laser 5 is regulated by the single-chip microcomputer 6 to emit an optical signal. The optical signal is transmitted through the optical fiber delay line 3 to the other end of the optical fiber delay line 3, and the optical signal is converted into an electrical signal by the photodetector 2. However, after being processed by the optical fiber delay line 3, the electrical signal is output from the output end of the optical fiber.

When the line is collected, the operation of the motor 2 12 is regulated by the single-chip microcomputer 6, and the output shaft of the motor 2 12 rotates in the opposite direction, driving the right side of the motor. The shaft 11 rotates in the opposite direction, thereby driving the optical fiber disc 10 to rotate in the opposite direction, so that the optical fiber delay line 3 on the optical fiber disc 10 begins to be gradually pulled back from the pay-off port 4 and the sliding port 99, so that it is gradually wound on the optical fiber disc 10. At the same time, the single-chip microcomputer 6 controls the operation of the motor 97, and the output shaft of the motor 97 rotates to drive the worm 98 to rotate. The worm 98 meshes and rotates with the worm wheel 96, so that the connecting rod 92 starts to rotate with the pin on the worm wheel 96 as the center. However, the other end of the connecting rod 92 is rotatably connected to the fixed plate 91 through the pin. Due to the length of the connecting rod 92 and The position of the rotating center pin of the worm gear 96 determines the movement trajectory of the fixed plate 91. Therefore, the movement of the connecting rod 92 causes the fixed plate 91 to reciprocate left and right around the rotating shaft 93, driving the turntable 94 to reciprocate left and right, and allowing the slide 99 to reciprocate with the turntable 94, guiding the optical fiber delay line 3 to reciprocate in the left and right directions, ensuring that the optical fiber delay line 3 is cross-laid during the process of being wound on the optical fiber reel 10, avoiding the cross-winding problem caused by stacking and the possible degradation of signal quality or transmission interruption in long-distance optical signal transmission.
