Specialty of optoelectronic information science and engineering is aim to cultivate senior specialized talents of photoelectric system design and implementation. The optical signal transmission is indispensable in the photovoltaic system. The problems existing in the teaching of information classes of the specialty at present are analysed and the teaching mode aiming to engineering training is proposed. The specific content is as follows: The principle problem of optical information transmission system is solved in the theoretical teaching in the classroom, the problem of the system design and simulation implementation is solved in the course design, the problem of the hardware implementation of the system is solved in the professional experiments. The training of the whole process from the principle of optical information transmission system design, software simulation to hardware implementation is achieved through this kind of teaching mode.
