光纤通信技术展望

在介绍目前广泛使用的光纤通信的基础上，针对波分复用的特点，分析提高光纤带宽资源的途径和影响通路数的因素，指出大量带宽资源有待于开发利用和利用有效带宽的途径，以适应未来更大容量和可持续升级的传输网络；同时对影响光通路光纤的非线性效应进行了理论分析和解决措施。未来的第三代光纤通信网络是要实现全光网络，对其中的关键单元进行了一些分析。

Prospects for Optical Fiber Communications

Becanse major problem of optical communication system is the limitation of the available frequency spectrum, with the character of optical wavelength-divislon multiplexing the paper analyzes the ways of broadbands raising and the limit factors of channels on the basis of introducing optical fiber communications, which should be developed in order to catch up with the needs of service capability and continuous upgrade networks in the future. Then the fion-linear character of optical communication is analyzed theoreti- cally so as to take measures to increase the limitation of the available frequency channels. Besides, as the third generation communication system is realized of optical transmitted network, main elements are analyzed finally.
