光纤通信是现代通信网的主要传输手段，它的发展历史只有一二十年，已经历三代：短波长多模光纤、长波长多模光纤和长波长单模光纤。</div><div><br></div><div> 光纤通信作为一门技术，其发展历史不过30——40年，但它已彻底改变了世界通信的面貌，未来发展更是不可估量。</div><div><br></div><div><p style="text-align: center;"><a

class="relatedlink">激光</a>器发出的激光束上，使光的强度随电信号的幅度（频率）变化而变化，并通过光纤发送出去；</div><div><br></div><div> 在接收端，检测器收到光信号后把它变换成电信号，经解调后恢复原信息。</div><div><br></div><div><font color="#f00000"><b>
