光纤通信的重要特点之一是其通信容量极大。140Mb/s的通信速率就相当于在单根光纤上传输1920路电话,这在技术上和经济上都有着重要意义。140Mb/s光端机试验系统的初步试验成功,使我们的光通信技术在较高速率的研究方面前进了一步,为下一步的研究以及可能的工程建设取得了一些第一手资料。 One of the important characteristics of optical fiber communication is its great communication capacity. The 140Mb / s communication rate is equivalent to transmitting 1920 phones over a single fiber, which is technically and economically important. The successful initial test of the 140Mb / s optical fiber terminal test system has enabled our optical communications technology to take a step forward in the research of higher speed and has obtained some first-hand information for the next research and possible project construction.
