作为高可靠性、快速和灵活调制的通信手段 ,全光通信需要实现全光互连。由于自由空间方案充分利用了光学系统固有的二维优势而显得更有竞争力。文中提出一个基于偏振编码 ,适用于动态光互连的方案 ,并给出全连接系统的增长规律。所提出的方案大大降低了互连系统的价格和复杂性 ,具有现实可行性 As a means of communication that is highly reliable, fast and flexible modulation, full optical communication requires full optical interconnection. The free-space solution appears to be more competitive because it takes full advantage of the inherent two-dimensional advantages of optical systems. In this paper, a scheme based on polarization coding is proposed, which is suitable for dynamic optical interconnection. The law of growth of fully connected system is given. The proposed solution greatly reduces the price and complexity of the interconnection system, with realistic feasibility
