光纤通信的诞生和发展是电信史上的一次重要革命与卫星通信、移动通信并列为20世纪90年代的技术。进入21世纪后，由于因特网业务的迅速发展和音频、视频、数据、多媒体应用的增长，对大容量（超高速和超长距离）光波传输系统和网络有了更为迫切的需求。

通信的发展过程是以不断提高载波频率来扩大通信容量的过程，光频作为载频已达通信载波的上限，因为光是一种频率极高的电磁波（3×1014Hz），因此用光作为载波进行通信容量极大，是过去通信方式的千百倍，具有极大的吸引力，光通信是人们早就追求的目标，也是通信发展的必然方向。
光纤通信与以往的电气通信相比，主要区别在于有很多优点：它传输频带宽、通信容量大；传输损耗低、中继距离长；线径细、重量轻，原料为石英，节省金属材料，有利于资源合理使用；绝缘、抗电磁干扰性能强；还具有抗腐蚀能力强、抗辐射能力强、可绕性好、无电火花、泄露小、保密性强等优点，可在特殊环境或军事上使用。
光纤通信的应用领域是很广泛的，主要用于市话中继线，光纤通信的优点在这里可以充分发挥，逐步取代电缆，得到广泛应用。还用于长途干线通信过去主要靠电缆、微波、卫星通信，现以逐步使用光纤通信并形成了占全球优势的比特传输方法；用于全球通信网、各国的公共电信网（如我国的国家一级干线、各省二级干线和县以下的支线）；它还用于高质量彩色的电视传输、工业生产现场监视和调度、交通监视控制指挥、城镇有线电视网、共用天线（CATV）系统，用于光纤局域网和其他如在飞机内、飞船内、舰艇内、矿井下、电力部门、军事及有腐蚀和有辐射等中使用。
