科學技術的相通性决定了軍用技術與民用技術之間没有不可逾越的鴻溝。發展迅猛的光纖通信技術就是軍民兩用技術的一個典型代表。尤其是近幾年來掺鉺光纖放大器與光孤子的研究取得重大突破,爲開發第五代光纖通信系統奠定了堅實的基礎。它的發展對人類的社會生活和軍事活動必將產生深刻的影響。 The interconnectivity of science and technology determines that there is no impassable gap between military technology and civilian technology. The rapid development of optical fiber communication technology is a typical representative of military and civilian dual-use technology. In particular, the research on erbium-doped fiber amplifiers and optical solitons has made major breakthroughs in recent years, laying a solid foundation for the development of the fifth generation optical fiber communication system. Its development will have a profound impact on human social life and military activities.
