40 Gbit/s data transfer ?

I need a very fast (ca. 40 GBit/s) interface from AGX Xavier to a PC.
From another post in this forum (https://devtalk.nvidia.com/default/topic/1047302/jetson-agx-xavier/pcie-external-thunderbolt-adapter-on-agx-xavier-/post/5314972/#5314972) I understood that the AGX Xavier doesn’t support external thunderbolt adapters.
Is there any third-party hardware that provides Thunderbolt 3 support for the Xavier?
Or, is there an alternative interface for the Xavier which provides a similar bandwidth?

Hi, Xavier support PCIe Gen4, 16Gbps per lane, x4 type should fit your request.
