摘　　要：本文先叙述现代通信技术进展最快的三项 ,即 :硅片集成密度、光纤传输能力、无线通信容量 ,其中特别引人瞩目的是一根光纤的实验传输速率已达 1Tb /s,意味着将使用“奇妙的飞秒”的光脉冲。文中又提到媒体数字化的重要技术 ,这将依靠“朴实的比特”发挥作用。The paper briefly describes the talk recently presented in Shanghai by Dr.Dan Stanzione.It explains the 3 items of telecommunication technology advancing very rapidly, they are the silicon chip integration density,optical fiber transmission capability, and wireless communication capacity, in particular the “fancy femtoseconds' light pulses along a single fiber. It also mentions the media digitization technology, by which the“ humble bits” would play important role in the future multimedia communications.
