【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.
