[0002] A fiber amplifier (OFA) is a new type of all-optical amplifier used in fiber-optic communication lines to amplify signals. Based on their location and function within the fiber optic line, they are generally categorized as relay amplifiers, preamplifiers, and power amplifiers. Compared to traditional semiconductor laser amplifiers (SOAs), OFAs eliminate the complex processes of photoelectric conversion, electro-optical conversion, and signal regeneration. They directly amplify signals all-optically, exhibiting excellent transparency and making them particularly suitable for relay amplification in long-distance optical communications.

[0003] When assembling an optical fiber line into an optical fiber amplifier, an optical fiber fixing head needs to be used to clamp it. However, the existing optical fiber fixing head does not clamp the optical fiber line firmly, which may cause the optical fiber line to loosen, thereby affecting the transmission effect of the optical fiber line. Utility Model Content

The two signal introduction channels are used to connect two optical fibers. An LED transmitting tube and an LED receiving tube are respectively installed in the two signal introduction channels. The rear ends of the two signal introduction channels are blocked by a black light-shielding sleeve.

[0007] The locking base is provided with a rotating lock and a locking slider. The rotating lock acts on the locking slider, and the locking slider is used to fix the optical fibers connected to the two signal introduction channels.

[0008] Furthermore, a mounting slot is provided on the front side of the locking base, the rotary lock and the locking slider are both located in the mounting slot, the locking slider is mounted on the locking base in a sliding manner, and the locking slider can slide up and down in the mounting slot;

[0009] Two semicircular butt joints are provided in the mounting slot of the locking base, and the two semicircular butt joints are respectively connected to the front ends of the two signal introduction channels. An oblong hole is provided in the middle of the locking slider, and a semicircular slot is provided at the lower end of the locking slider. The oblong hole and the semicircular slot are respectively matched with the two semicircular butt joints.

[0010] The rotating lock acts on the locking slider, so that when the locking slider slides downward, the two optical fibers are clamped and fixed through the cooperation between the oblong hole and the semicircular butt joint tube, and the cooperation between the semicircular slot and the other semicircular butt joint tube.

[0011] Furthermore, long holes are provided on opposite sides of the installation slot, and ridges are provided on opposite sides of the locking slider. The two ridges are respectively located in the two long holes, and the ridges can move up and down in the long holes.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] The present invention is further described in detail below with reference to the embodiments.

[0021] like Figure 1-3 As shown, a specific embodiment of a fiber optic locking and fixing module for a fiber optic amplifier provided by the present invention is as follows:

[0022] A fiber optic locking and fixing module for an optical fiber amplifier includes a locking base 1. Two signal introduction channels 2 are provided at the rear of the locking base 1. The two signal introduction channels 2 are used to connect two optical fibers. An LED transmitting tube 3 and an LED receiving tube 4 are respectively installed in the two signal introduction channels 2. The rear ends of the two signal introduction channels 2 are blocked by a black light-shielding sleeve 5. The black light-shielding sleeve 5 can reduce external light interference, protect the LED sensor, and improve the accuracy of signal detection.

[0023] The locking base 1 is provided with a rotary lock 6 and a locking slider 7 . The rotary lock 6 acts on the locking slider 7 . The locking slider 7 is used to fix the optical fibers connected to the two signal introduction channels 2 .

[0024] The front side of the locking base 1 is provided with a mounting slot 8, the rotary lock buckle 6 and the locking slider 7 are both located in the mounting slot 8, the locking slider 7 is mounted on the locking base 1 in a sliding manner, and the locking slider 7 can slide up and down in the mounting slot 8. Specifically, long hole bodies 9 are provided on opposite sides of the mounting slot 8, and ridges 10 are provided on opposite sides of the locking slider 7. The two ridges 10 are respectively located in the two long hole bodies 9, and the ridges 10 can move up and down in the long hole bodies 9.

[0025] Two semicircular butt joints 11 are provided in the mounting slot 8 of the locking base 1. The two semicircular butt joints 11 are respectively connected to the front ends of the two signal introduction channels 2. An oblong hole 12 is provided in the middle of the locking slider 7. A semicircular slot 13 is provided at the lower end of the locking slider 7. The oblong hole 12 and the semicircular slot 13 are respectively matched with the two semicircular butt joints 11.

[0026] The rotating lock 6 acts on the locking slider 7, so that when the locking slider 7 slides downward, the two optical fibers are clamped and fixed through the cooperation between the oblong hole 12 and the semicircular butt joint 11, and the cooperation between the semicircular slot 13 and the other semicircular butt joint 11.

[0027] The cooperation between the rotary lock buckle 6 and the locking slider 7 is as follows: the top of the rotary lock buckle 6 is a trigger buckle groove 14, the middle of the rotary lock buckle 6 is provided with a hinge shaft 15, and the lower end of the rotary lock buckle 6 is provided with a short column 16. The rotary lock buckle 6 is hingedly mounted on the upper part of the installation slot 8 through the hinge shaft 15;

[0028] A transverse hole 17 is provided at the upper end of the locking slider 7 , and the short column 16 of the rotary lock 6 is located in the transverse hole 17 . When the locking slider 7 clamps and fixes two optical fibers, the short column 16 is located at the front end of the transverse hole 17 .

[0029] When using this embodiment, first, two optical fibers are respectively inserted into the two signal introduction channels 2 through the two semicircular butt joints 11, and then the trigger groove 14 is pulled upward to make the rotary lock buckle 6 rotate clockwise around the hinge shaft 15 to a certain angle. During the rotation of the rotary lock buckle 6, the short column 16 at the lower end of the rotary lock buckle 6 pushes the locking slider 7 downward, so that the oblong hole 12 and the semicircular butt joint 11 clamp one of the optical fibers, and the semicircular slot 13 and the other semicircular butt joint 11 clamp the other optical fiber, until the short column 16 moves to the front end of the transverse hole 17, completing the locking and fixing of the optical fiber. Figure 1 shown.

[0030] When two optical fibers need to be removed, the trigger groove 14 is pulled downward to make the rotary lock 6 rotate counterclockwise. The short column 16 at the lower end of the rotary lock 6 pulls the locking slider 7 upward, and the locking slider 7 moves upward. Finally, the oblong hole 12 is separated from the semicircular butt joint 11, and the semicircular card groove 13 is separated from the other semicircular butt joint 11, thereby releasing the fixation of the optical fiber and allowing the optical fiber to be pulled out.
