摘要： 扩频微波技术是近几年发展起来的高新技术,是目前发展宽带网络技术的主要手段之一。采用扩频微波方式组网在地震系统还尚属首次。“京区扩频微波高速链路建设” 是采用2～3M bp/s速率扩频微波技术将中国地震局京区主要直属单位及北京市地震局的计算机网络互联起来,构成中国地震局北京城区计算机网络互联的计算机广域网扩频微波网络平台及中国地震局北京城区计算机网络信道骨干网。同时利用扩频微波建立了与中国科技网相连的信道,将京区各单位和全国各省(市)地震局的计算机网络接入因特网。

Abstract: The high speed frequency spread microwave technique is a high technology developed in recent years, which is the main means used in developing the wide band network technology. It is first time to adopt the high-speed frequency spread microwave network for China Seismological Bureau. In the project of " The Construction of the High Speed Frequency Spread Microwave Linkage in the Beijing Area", the frequency spread microwave of 2 to 3 Mbps has been used to link the computer networks at the institutions of China Seismological Bureau in Beijing area (Center for analysis and Prediction, Seismic Data and Information Center, The Institute of Geophysics, the Institute of Geology, the Institute of Crustal Dynamics and the Center of Comprehensive Observations) and the Seismological Bureau of Beijing Municipality, to form a platform of computer WAN frequency spread microwave network that link the computer networks in the area. At the same time, a communication channel to the China Science and Tech nology Network has been set up with the frequency spread micro wave so that the computer networks at the institutions in the Beijing area and in the provincial (or municipal) bureaus all over the country have been linked to Internet.
