摘要

【目的】

文章旨在改进多层光纤布线结构，提高其抗压性能，进行压力分布优化实验研究，并提出一种多维光交叉互连柔性光背板压力分布优化结构和设计方法。

【方法】

文章通过改进多层光纤布线结构，利用实验分析不同光纤交叉方式，研究在相同压力下光纤排布、光纤交叉点的密度和光纤交叠层数等因素对光纤损耗的影响，由此提出一种优化光背板压力分布的双层背板理想光纤布线结构。

【结果】

由实验结果提出的理想双层布线结构采用双层背板和每个背板中的多层光纤优化布线，将两层柔性光背板进行上下叠加，光纤的布线方案采用光纤端口均匀分布在背板的4个边缘，且同一层级光纤紧密排布，交叠两层光纤于交叉点处。通过多层光纤交叉及错位叠加的布局，可实现多层光纤交叉互连布线优化分布，以提高光背板的抗压性能，从而提高其光传输交换的整体性能。

【结论】

文章所提方案光背板具有更小的体积、更好的抗压性能和更好的光信号传输损耗性能，能够实现更大面积、高密度和大容量柔性

光背板，具有良好的可拓展性，并使光纤布线工作更加简单和方便。

Abstract

【Objective】

This paper aims to improve the multi-layer optical fiber wiring structure and the pressure resistance. An experimental research on pressure distribution optimization is conducted. A multi-dimensional optical cross-interconnection flexible optical backplane pressure distribution optimization structure and design method are also proposed.

【Methods】

This paper uses experimental analysis of different optical fiber crossing methods to study the influence of optical fiber arrangement

fiber intersection density and number of optical fiber overlap layers on optical fiber loss under the same pressure. It also proposes an ideal optical fiber wiring structure of double-layer backplane with optimized optical backplane pressure distribution.

【Results】

The proposed ideal double-layer wiring structure adopts double-layer backplanes and optimized wiring of multiple layers of optical fibers in each backplane. The two flexible optical backplanes are stacked vertically

with the optical fiber ports evenly distributed along the four edges of the backplanes. Additionally

the optical fibers of the same layer are tightly arranged

and two layers of optical fibers overlap at the crossing points.By utilizing the layout of multi-layer optical fiber crossings and staggered overlays

an optimized distribution of multi-layer optical fiber cross-interconnect wiring can be achieved

enhancing the compressive resistance of the optical backplane and thereby improving its overall optical transmission and switching performance.

【Conclusion】

The proposed scheme features an optical backplane with a smaller volume

better compressive resistance

and improved optical signal transmission loss performance. It enables the realization of larger-area

high-density

and high-capacity flexible n×n optical backplanes with excellent scalability

making fiber optic wiring work simpler and more convenient.
