[0002] Fiber amplifier refers to a new type of all-optical amplifier used in fiber-optic communication lines to achieve signal amplification. According to its position and function in the fiber-optic line, it is generally divided into three types: relay amplifier, preamplifier and power amplifier. Fiber amplifier plays a vital role in optical communication systems. It is used to enhance the intensity and transmission distance of optical signals and improve the performance of fiber-optic communication systems.

[0003] The existing protection for the optical fiber amplifier is usually to provide a flip-connected transparent cover at the button on the top of the optical fiber amplifier. However, the flip-type transparent top cover is not convenient to open at a large angle and is easy to collide with human hands, causing inconvenience in maintenance work. At the same time, the existing amplifier box can only dissipate heat through the heat dissipation holes on the side wall, and cannot achieve effective and targeted heat dissipation of the optical device body, which will affect the normal operation of the optical fiber amplifier. After the optical fiber cable is connected to the amplifier box, it is not convenient to fix the cable, and when the cable shakes or moves, it causes instability and interruption of signal transmission.
