纤维光学技术已经由它的初期发展到大规模的商用通信网络,乃至在军用系统得到了有限的应用。选用光纤的明显的原因是带宽、重量轻和体积小,此外,还有各种潜在的应用场合,例如需要工作在有害的敌对环境条件下。能够工作在上述应用场合下的光纤,一定要能对付下列环境:从高空大气层中的极低温度到靠近发电机旁的很高温度;从太空的低剂量电离辐射到核反应堆的很强的中子辐照;此外,还有来自船上系统的盐雾 Fiber optic technology has been its initial development to large-scale commercial communications networks, and even military applications have been limited. Obvious reasons for using optical fiber are bandwidth, light weight and small size, and there are potential applications, such as the need to work in hostile, hostile environments. An optical fiber that can work in these applications must be able to handle the following environments: from very low temperatures in the upper atmosphere to very high temperatures near generators; from neutrons that radiate low doses of ionizing radiation in space to nuclear reactors Irradiation; in addition, salt spray from the ship’s system
