摘要
提出了基于波分复用光纤传输的通信教学系统及实验案例。利用原有各门课程的实验器材设计通信系统教学方案,再进行硬件模块组合和程序编写调试,然后测试分析。结果表明,利用多个波分复用光纤信道开展综合实验,有利于学生在有限时间内全面理解通信系统的概念,高效地掌握专业知识,提高实验技能。此外,可形成新的通信实验体系,在不增加经费的情况下推进通信专业实验和理论教学体系的改革。
A comprehensive design and a teaching method for communication experiment were developed in this paper based on wavelength division multiplexing（ WDM） optical fiber transportation. The designed communication experimental equipment was combined by the ones used in other courses such as principle communication,optical fiber communication,program-controlled switching etc., where the modules of signal generator and processing were distributed in different experimental instruments,the signals can be transferred via the WDM channels in optical fiber.The results indicate the integrated experiments can facilitate students to comprehensively understand the communication technology,to improve practical skills and to effectively grasp the key concepts in limited time. In addition,the designed experimental system will contribute to adjust the experimental items and to reform the theoretical teaching without extra fees.
