摘　　要：文章论述了当前光通信系统的工作温度范围受到的限制,介绍了光通信系统中常用的几种散热方式。根据半导体致冷器的工作原理及特点,提出了利用半导体致冷器扩展光通信系统工作温度范围的方案,最后通过成品试验验证了半导体致冷器在扩展光通信系统工作温度范围中的实际使用效果。The limitation of the working temperature range of current optical communication system is discussed. Several heat dissipation modes commonly used in optical communication system are introduced. According to the working principle and characteristics of semiconductor refrigerators, a scheme of expanding the operating temperature range of optical communication system by using semiconductor refrigerators is proposed. Finally, the practical application effect of semiconductor refrigerators in expanding the operating temperature range of optical communication system is verified by the test of finished products.
