攀钢有线电视系统始建于1986年,是国内首先采用多模光纤技术传输电视信号的大型 CATV 系统。1989年单模光纤传输技术在美国首先应用,90年代初,攀钢有线电视系统又率先用单模光纤取代多模光纤来传输多路电视信号获得成
Panzhihua Iron and Steel Cable Television System was founded in 1986, is the first large-scale CATV system using multimode fiber technology to transmit television signals. In 1989 the single-mode optical fiber transmission technology was first applied in the United States. In the early 1990’s, Panzhihua Iron and Steel Cable Television System took the lead to replace multimode optical fiber with single-mode optical fiber to transmit multi-channel television signals
