【摘要】 面向航空电子应用的FC网络是一种具有确定性和实时性的通信网络。由于WDM具有轻质、高容量、多协议透明传输等多种优点,以波分复用为特征的先进光网络已经成为未来航空机载网络的技术选择目标。针对航空电子网络发展趋势,提出一种基于FC over WDM的航电光纤网络架构。该架构兼容了航电系统对延迟确定性和带宽可扩展性的需求,可实现对现有FC航电光纤网络的平滑升级。通过采用自主研制的FC仿真卡建立地面仿真环境对该架构进行实验仿真,从功能和系统性能两个方面验证了在航电光纤网络中引入WDM和光交换技术的合理性。更多还原

【Abstract】 The Avionic oriented Fibre Channel network is a real-time and deterministic communication network. Optical network with wavelength division multiplexing(WDM) transmission technology has been targeted as the technology of choice to realize the desired avionic network of the future due to its lightness, high-capacity and transparency to multi-protocols. Based on the trend towards avionic network, we propose a fiber channel(FC) over WDM architecture on avionic network. The delay deterministic of FC and the bandwidth extensibility of WDM are integrated to satisfy the communication requirements of avionic network, and the existing avionics FC network can be seamlessly upgraded. We establish an FC over WDM ground experimental environment based on independently developed FC emulator, and the experimental results on functional verification and system performance analysis indicate that the adoption of WDM and optical switching in avionics fiber-optic network is feasible.更多还原
