90年代用户对信息的需求日益迫切,因此信息通讯技术也变得非常复杂。信息网络之间的连接成为主要任务之一,连接信息网络的通信介质显得非常重要。70年代就出现了弯曲式计算机和远程通信系统。以往的传输介质——铜线电缆造价高、传输精度低、寿命短,很难适应远程通信。以光学纤维为介质的电缆从80年代以来已经成为网络连接的主要手段。大家所了解的光波导向、光学纤维、利用玻璃纤维传递信号的纤维光学是一门新兴的学科。玻璃纤维技术就其本身来说是一门较古老的学科。玻璃纤维的生成可追溯到17世纪的威尼斯人,他们把玻
As the demand for information by users has become increasingly urgent in the 1990s, information and communication technologies have also become very complex. The connection between information networks has become one of the main tasks. It is very important to connect the communication media of the information network. In the 1970s, curved computers and telecommunications systems emerged. The previous transmission medium - copper cable high cost, low transmission accuracy, short life expectancy, it is difficult to adapt to long-range communications. Optical fiber-based cables have been the primary means of network connectivity since the 1980s. As we all know, optical guidance, fiber optics, and fiber optics that use glass fiber to transmit signals are an emerging discipline. Fiberglass technology is by itself an older discipline. The generation of glass fibers dates back to the 17th century Venetian, they put glass
