随着我国经济的逐渐发展,通信设备也发展迅速,通信介质也有了质的改变,常用的通信介质有双绞线、非屏蔽双绞线、同轴电缆和光纤等,光纤是近几年才有的通信介质,它具有传输速度快、能防止信息泄露等优点,而且材料环保,因此受到了通信业的强烈关注和倍加信赖。信息化迅速发展的今天,各个行业都需要用电,而且,一旦断电,造成的损失无法估计,电力通信具有很高的要求,将光纤应用于电力通信网络中有很高的现实意义。
With the gradual development of economy in our country, the communication equipment has also developed rapidly and the communication medium has also been changed in quality. Commonly used communication media include twisted pair, unshielded twisted pair, coaxial cable and optical fiber. In recent years, Some communication media, it has the advantages of fast transmission, to prevent the disclosure of information, and environmental protection, and therefore by the communications industry, a strong concern and double trust. Today’s rapid development of information technology, all industries need electricity, and, once the power outages, the resulting loss can not be estimated, power communication with high requirements, the optical fiber used in power communication network has a high practical significance.
