一九九七年十一月份,天津津达资讯设备有限公司生产的首批100台“JPLM-100”电力线调制解调器投放市场。 电力线调制解调器是计算机信息通讯中一种技术新颖的网络互连设备。它将数据信号调制在220V、50HZ交流电上,利用电力线网络的生产车间、办公室以及楼宇之间的电力线简便、快捷地组成计算机网络。使用、“JPLM100”不需要传统的服务器、集线器网卡、综合布线、网络软件等设备,只需将其插头插入220V电源线的插座内,就可快捷地进行100KBPS的数据传送工作。该产品的最大突破,在于解决了电力线上杂波干扰及负载
In November 1997, the first 100 “JPLM-100” power line modems produced by Tianjin Jin Da Information Equipment Co., Ltd. were put on the market. Power line modem is a kind of novel network interconnection equipment in computer information communication. It modulates the data signal in 220V, 50HZ alternating current, uses the power line network production workshop, the office as well as the power line between the buildings simple, quick composition computer network. Use, “JPLM100” does not require the traditional server, hub network card, integrated wiring, network software and other equipment, simply plug the 220V power cord into the socket, you can quickly 100KBPS data transfer. The biggest breakthrough of this product lies in solving clutter interference and load on the power line
