DETAILED DESCRIPTION

[0021] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] like Figures 1-7 As shown, a low-noise erbium-doped fiber amplifier includes a housing 1, and a front side plate 4 and a rear side plate 7 detachably mounted on both sides of the housing 1. A mounting plate 2 is mounted on the side of the front side plate 4 closest to the housing 1. An electronic component 3 is mounted on the top of the mounting plate 2, which is attached to one side of the front side plate 4. A control panel electrically connected to the electronic component 3 is located on the outer side of the front side plate 4. A soundproof cover 5, attached to the inner wall of the housing 1, is fitted inside the housing 1. Both inner walls of the soundproof cover 5 are equipped with sound-absorbing mechanisms, each including a sound-absorbing plate 10 mounted on the sound-absorbing plate 10. Multiple sound-absorbing strips 11 are evenly spaced on one side of the sound-absorbing panel 10, and clamping plates 16 are installed on the top and bottom of the sound-absorbing panel 10. The top and bottom of the soundproof cover 5 are provided with clamping slots 15 that cooperate with the clamping plates 16. Limiting frames 6 are installed on both sides of the soundproof cover 5. Limiting grooves 12 that cooperate with the limiting frames 6 are provided on the side of the front side panel 4 and the rear side panel 7 near the outer shell 1. Two support plates 8 that fit snugly against the bottom of the outer shell 1 are installed on the bottom of the mounting plate 2. Two moving grooves 9 that cooperate with the two support plates 8 are provided on one side of the bottom of the soundproof cover 5. When… When the soundproof cover 5 slides inside the outer shell 1, the two support plates 8 will be located in the two moving slots 9 respectively. At this time, the soundproof cover 5 will move below the mounting plate 2, thus fitting against the inner wall of the outer shell 1. The clamping plate 16 is slidably connected in the clamping slot 15 and forms a fixing slot on the side away from the front side plate 4. Multiple fixing blocks 13 that cooperate with the fixing slot are installed on one side of the rear side plate 7. First mounting holes 18 are opened at the four corners of both sides of the outer shell 1, and second mounting holes that cooperate with the first mounting holes 18 are opened at the four corners of the front side plate 4 and the rear side plate 7. 17. The first mounting hole 18 and the second mounting hole 17 are fixedly connected by bolts 14. When it is necessary to disassemble the front side plate 4 and the rear side plate 7, the corresponding bolts 14 can be unscrewed from the outer shell 1. When the electronic component 3 inside the outer shell 1 is damaged and needs to be repaired, the front side plate 4 can be directly removed from the outer shell 1. At this time, the front side plate 4 can be pulled directly. During the process of pulling the front side plate 4, the mounting plate 2 will drive the electronic component 3 to slide out from the inside of the outer shell 1, which facilitates the repair of the electronic component 3.

[0023] It should be noted that the low-noise doped fiber amplifier can absorb the noise generated in the doped fiber amplifier through the sound-absorbing strips 11 and sound-absorbing plates 10, reduce the conduction to the outside, and further intercept the generated noise through the soundproof cover 5, double noise reduction, thereby reducing the noise generated during use of the doped fiber amplifier. When it is necessary to replace the sound-absorbing strips 11 and the soundproof cover 5, the rear plate 7 can be detached from one side of the shell 1, and then the soundproof cover 5 can be pulled out from the inside of the shell 1, so that the soundproof cover 5 can be directly removed. After the soundproof cover 5 is removed, the sound-absorbing plate 10 can be directly pulled out from one side of the soundproof cover 5. At this time, the clamping plate 16 will slide in the clamping groove 15. When it is necessary to install the new soundproof cover 5 and sound-absorbing strips 11, the soundproof cover 5 is first pushed into the inside of the shell 1 from one side of the shell 1. At this time, the limiting frame 6 close to the front plate 4 side of the soundproof cover 5 will move into the limiting groove 12 opened on the front plate 4 side. Then the sound-absorbing plate 10 is slidably connected to the inner side wall of the soundproof cover 5. At this time, the clamping plate 16 will be slidably connected in the clamping groove 15, and the clamping plate 16 will be limited by the clamping groove 15, so as to limit the sound-absorbing plate 10. When the clamping plate 16 is completely slidably connected in the clamping groove 15, a fixed groove will be formed between the clamping plate 16 and the clamping groove 15 close to the rear plate 7 side. The rear plate 7 is installed on one side of the shell 1. At this time, the fixing block 13 is located in the fixed groove, and the clamping plate 16 is further limited. The limiting frame 6 close to the rear plate 7 side of the soundproof cover 5 will move into the limiting groove 12 opened on the rear plate 7 side. At this time, the soundproof cover 5 is fixed in the inside of the shell 1, and the installation of the soundproof cover 5 and the sound-absorbing plate 10 is completed. In this way, the soundproof cover 5 and the sound-absorbing plate 10 can be easily disassembled and cleaned, and when the soundproof cover 5 and the sound-absorbing plate 10 are aged, they can be replaced regularly to ensure the noise reduction effect.
