Description

Technical field: [0001] The invention relates to a teaching and demonstration teaching aid, in particular to a simulation demonstration device for optical fiber communication. Background technique: [0002] With the development of optical fiber communication, mastering the knowledge of optical fiber communication has become a new important content in teaching. Compared with cable communication, the working principle of optical fiber communication is similar, the only difference is that the carrier of the transmission signal is laser instead of radio wave, which has the advantages of large communication capacity, low loss, strong anti-interference ability, and good confidentiality performance. There are more theory than practice in current textbooks, especially in schools in some disadvantaged areas, there is no demonstration teaching aid, and teachers can only draw pictures on the blackboard to explain in detail, which makes it difficult for students to understand and cause ...
