摘要
针对机载航电系统光互联网络高密度、高可靠及抗恶劣环境等特点,在对比了印制光—电路板及光纤电路技术优缺点的基础上,引入MT光纤接口,基于光电混装连接嚣,设计并实现了一种应用于机载航电系统的光背板,并对其进行了测试和实验验证;结果表明:光背板各路MT接口的光损值控制在要求范围内,且通过了高低温、冲击振动等抗恶劣环境试验,能满足机载航电系统应用需求,是一种值得推广的方法。
Based on the comparison of Optical--Electronic Circuit Board and Fiber optic circuit technology and the characteristics of relia- ble high density and anti harsh environment of Airborne Avionics System, this paper introduced MT ferrule and photoelectric mixed connec- tor, designed an Optic Backplane for Airborne Avionics System. Tests showed that the Optic Backplane, whose optical losses are within re- quired range, can pass the high and low temperature, vibration and shock test, which means that the Optical Backplane can satisfy the re- quirements of Airborne Avionics System and worth wldelv oooularized.
