随着我国科学技术的发展,对干线通信系统传输质量的要求越来越高。本文以120路海底干线通信系统(浅海)电缆衰减测试为例,着重研讨了以D120可变衰减箱为主体的衰减测试系统之建立和实施过程。同时,对进一步减小相对误差提出了看法。
With the development of science and technology in our country, the requirements on the transmission quality of the trunk communication system are getting higher and higher. In this paper, the 120-line submarine trunk communication system (shallow sea) cable attenuation test as an example, focuses on the D120 variable attenuation box as the main attenuation test system to establish and implement the process. At the same time, we put forward some suggestions to further reduce the relative error.
