Research and design of spaceborne 100G high-capacity switching hardware platform

With the development of laser communication, inter-satellite communication requires higher communication capacity. The spaceborne100G high-capacity switching hardware platform is a key component of inter-satellite communication. To address the limitations of immature 100G spaceborne optical modules, this paper proposes a 100G high capacity switching hardware platform based on electrical interfaces. Leveraging the Virtex UltraScale+ VU13P FPGA with radiation-hardened reconfiguration technology, the platform achieves a switching capacity of 400G, supports in-orbit refresh, and ensures 100% component localization.
