The invention discloses a preferred cleanable optical fiber panel which includes a panel body and a cleaning device. The cleaning device is installed on one side of the panel body. The cleaning device includes a liquid storage box and a wiping sheet. The liquid storage box has a gap used to place the wiping sheet so the wiping sheet is communicated with the cavity of the liquid storage box. The wiping sheet contacts and absorbs the liquid disinfectant in the liquid storage box. An optical fiber connector is cleaned by rubbing the wiping sheet. Before the optical fiber connector is inserted into an optical fiber interface, the liquid storage box is squeezed by hand to make the alcoholic solution in the liquid storage box saturate the wiping sheet, and the optical fiber connector rubs the wiping sheet and then the brush. After that, the optical fiber connector is inserted into the optical fiber interface. Therefore, dust and impurities on the optical fiber connector are all cleaned, good contact between the optical fiber connector and the optical fiber interface is guaranteed, and normal work is ensured.
