Abstract: An optical transceiver includes an input assembly, an output port, a fiber patch panel, multiple first optical fibers and multiple second optical fibers. The input assembly is arranged on a circuit board and has a first input port and a second input port. The fiber patch panel is arranged between the input assembly and the output port, and has multiple first fiber patch slots and multiple second fiber patch slots. The first optical fibers are connected to the first input port and the output port. The first optical fiber passes through the first fiber patch slot and the second fiber patch slot. The second optical fibers are connected to the second input port and the output port. The second optical fiber passes through the first fiber patch slot and the second fiber patch slot. The second fiber patch slot accommodates the first optical fiber and the second optical fiber.

Abstract: A ventilating cleaning assembly includes a cleaning agent bottle, a cover, and a cleaning cloth. The cleaning agent bottle has an opening end and a bottom end opposite to each other. The cover has an open end and a closed end opposite to each other. The open end of the cover is detachably assembled to the cleaning agent bottle. An accommodating room is formed between an upper portion of the cover and the cleaning agent bottle. A plurality of permeable holes are formed in a peripheral wall of the cover corresponding to the accommodating room. The cleaning cloth is stored in the accommodating room. The cleaning agent bottle and the cleaning cloth are integrated together by utilizing the cover. In addition, the cleaning cloth stored in the accommodating room of the cover can be kept dry because of the permeable holes of the cover.
