Abstract: The quality of optical fiber communications experimental teaching has a very important impact on building the students’ creative ability. In order to improve the creative ability of the undergraduates whose majors are in communications and electronics information, based on the analysis of conventional experimental teaching case for optical fiber communications, the improvement of both the experimental platform and the experimental teaching exploration are highly depicted. The improvement type of experimental teaching will improve the teaching effects, enhance undergraduates’ manipulative ability and inspire their creative ability.
