能够传播光的纤维丝称作“光导纤维”，简称“光纤”。信息高速公路就是以现代通信技术和计算机网络为基础，用大容量的光纤作为铺“路”材料，集话音、数据、图像和文字为一体的多媒体信息源为“车”，这些“路”和“车”便构成了“信息高速公路”。对光纤的研究、开发和利用 Fiber filaments capable of propagating light are called “optical fibers,” or “optical fibers” for short. Information superhighways are based on modern communication technologies and computer networks. They use large-capacity optical fiber as the “road” material, and multimedia information sources integrating voice, data, images and texts are “vehicles”. These “roads” and “Car” will constitute a “information highway.” Research, development and utilization of optical fibers
