针对模块化子阵间数据实时传输需求,设计了基于FC over波分复用(WDM)架构的光纤传输系统,在物理层采用WDM技术和无源光网络(PON),建立了模块化数字阵列间数据传输通道,在链路层使用轻量化FC协议,减少了协议封装、解析所带来的成本,增强了传输的实时性。文中以16子阵规模的光纤传输系统为例,详细阐述了模块化阵列重构的具体实现方法。该光纤传输系统满足开放式、可重构阵列发展技术要求,具有较优的先进性,在未来智能化、软件化数字雷达领域具有较好的应用前景。

For solving real-time data transmission problem between modular digital arrays, a new fiber-optic transmission system is proposed with FC over WDM architecture. WDM technique and PON are adopted for establishing the data-transmission channel between modular digital arrays. Meanwhile, FC-Lite protocol is used in the link layer, which reduces the cost of protocol encapsulation and parsing, beyond that, it enhances the real-time performance of transmission. In this paper, a 16-subarray fiber-optic transmission system is taken as an example, and the paper describes the realization of modular array reconstruction in detail. This fiber-optic transmission system can meet the requirement of open-ended and reconfigurable array, and has more extensive application prospects in intelligentized software digital radar field.
