This paper presents the development of a new versatile portable add-on converter module which can be used for analysing mobile communication and cable TV networks. Present testing techniques required separate test equipment for characterising electrical and optical networks. Here, we develop a new system work as an add-on module for electrical frequency domain reflectometer which can perform measurements in electrical as well as optical cable networks. Using this technique, millions of electrical cable analyser currently in use all over the world can be converted into the optical analyser. The same system can also be configured as a bidirectional communication system for a wide variety of applications like fibre to the antenna/fibre to the home, cable TV applications. We also show that the developed system has wideband performance over a frequency range from 800 MHz to 2.5 GHz and a dynamic range of 45 dB.

一个简单便携式的附加转换器模块，用于通信和测量

本文介绍了一种新型多功能便携式附加转换器模块的开发，该模块可用于分析移动通信和有线电视网络。当前的测试技术需要用于表征电气和光学网络的单独测试设备。在这里，我们开发了一个新的系统，作为电气频域反射仪的附加模块，可以在电气和光缆网络中执行测量。使用这种技术，可以将全球目前使用的数百万条电缆分析仪转换为光学分析仪。同一系统还可以配置为双向通信系统，用于多种应用，例如光纤到天线/光纤到家庭，有线电视应用。
