The principle and system of optical fiber communication is an important course for the major olOpto -lectronics information science and engineering.The purpose of this course is to enable students to fully understand the basie knowledge of optical fiber communication , and to cultivate students’ basic skills of opticafiber communication and the application skills of new technologies and new methods.In recent years, the rapiddevelopment of optical fiber communication technology has also led to a huge increase in the capacity and speed of optical fiber communication systems. Meanwhile, the synergy between oplical fiber communication teaching and scientilic research has become an important starting point for cultivating students’ innovativescientifie research thinking ability and practical ability. This research describes some attempts of integrating thescientilic research progress into the teaching, including the introduction of optical fiber communication systemsimulation software Optisystem to construct the detailed visual structure of optical transmitter, optical fibertrans mission line and optical receiver of optical fiber communication system. Furthermore, the dynamic characteristies of signal eye diagram and bit error rate of optical fiber communication system are analyzed.Through the way of scientific research backeeding teaching,the practical results of optical fiber communication research are introduced into teaching. 0n the one hand, the basic concepts and workflow in thecourse of optical fiber communication principle and system can be more intuitive.0n the other hand, it can cultivate students’ scientifie research innovative thinking and practical ability. The teaching reform and practicehave certain signilicance for cultivating academic talents of Opto-lectronics information science and engineering with innovative spirit and innovative consciousness.
