The main components of XFP optical module include optical transmitter, optical receiver, functional circuit and optical interface. The advantages of XFP optical module include low price, small size and wide application environment. Because the optical port of the optical module must be kept clean, if it is exposed to the air for a long time, a lot of dust will enter and block the optical port, thus affecting the normal transmission of optical signals. During the storage, transportation and use of optical modules, attention should be paid to environmental dust prevention. There is a large gap between the fiber plug-in board and the shell of the existing XFP optical module. When in use, dust in the equipment will enter the optical module through the gap, thereby reducing the service life of the optical module. In addition, the existing dust-blocking structure is usually installed with the optical module, and the optical module must be disassembled for cleaning, which makes dust cleaning very inconvenient.
