10GbE

From dankwiki

10 Gigabit Ethernet achieves 10Gbs data rates using the Ethernet Layer 2 protocol over a variety of media, usually using SFP+ transceivers. It is defined on CAT-6A copper, twinaxial, and fibre. CAT-5e and CAT-6 can also be used, but not for the full 100m of 10GBASE-T (IEEE 802.3an-2006).

100GbE NICs

PCIe 2.0 at 4 lanes doesn't have sufficient throughput to carry a full 10Gbps. At least 8 lanes of PCIe 2.x are required. 2 lanes of PCIe 3.0 or a single lane of PCIe 4.0 will also suffice.
