目前,通信线路大多采用光缆,从多模光缆到单模光缆,从室外光缆到室内光缆,从干线光缆到接入光缆,十几年来随着光通信技术的极大提高呈现迅猛发展的趋势。从事通信岗位的技术人员要不断立足国内,跟踪新技术前沿,瞄准国内外发展动态,不断提高通信保障水平。随着光通信系统的发展,
At present, communication lines mostly use optical cables. From multi-mode optical cables to single-mode optical cables, from outdoor optical cables to indoor optical cables, from trunk optical cables to optical fiber cables, the optical communication technology has shown a trend of rapid development over the past decade. Technical staff engaged in communications positions should keep their footing in the country, track the frontiers of new technologies, aim at the developments both at home and abroad, and constantly raise the level of communication and security. With the development of optical communication system,
