在美国马黑兰Aberdeen Proving美军基地的武器试验区已经敷设了多模光缆。光缆维持了试验和训练设备的保密性,且其功能将来还可升级提高。这种光缆结构也便于把许多光纤分别联到各种不同的目标场所。位于巴尔的摩外面的Aberdeen基地是美军用来试验点火系统的军械、装备和运载工具的基地。光缆系统把位于下靶场纤维玻璃人孔内的目标数据采集设备连到上靶场计算机房的数据分析设备上。炮弹的射程、速度和方向在模拟试验期间被电视录象下来。采用光缆作传输媒质几乎能够瞬时地读出数据。这种直接的反馈使美军下决心来校正已经使用的仪器和武器的精度。N.C.,Hickory的Siecor公司根据190万美元的合同为美军提供光缆并负责安装。光缆结构是多模小捆扎型,内有中心钢丝件,外带铠装护 Multimode fiber optic cables have been laid in the weapons test area at Aberdeen Proving U.S. Base in Mahran, the United States. Optical cables maintain the confidentiality of test and training equipment and their functionality can be upgraded and upgraded in the future. This fiber optic cable structure also facilitates the connection of many optical fibers to a variety of different destination locations. The Aberdeen base outside of Baltimore is the base of ordnance, equipment and vehicles used by the U.S. military to test ignition systems. The cable system connects the target data acquisition equipment located in the fiberglass manhole of the down range to the data analysis equipment of the computer room on the upper range. The range, speed and direction of the projectile were video-recorded during the simulation test. The use of optical fiber as a transmission medium can almost instantaneously read the data. This direct feedback gives the U.S. military the determination to correct the accuracy of the instruments and weapons already in use. N.C., Hickory’s Siecor Corp. supplies fiber optic cables to the U.S. military under a $ 1.9 million contract and is responsible for installation. Fiber optic cable structure is a multi-mode small bundled type, there are central wire pieces, with armor protection
