The SD-PEX24055 NIC supports 10GBASE-T Ethernet in compliance with the IEEE 802.3an standard, as well as 5 Gbps and 2.5 Gbps Ethernet speeds over standard Cat 5e and Cat 6 copper cables. Compliant to the IEEE 802.3bz standard ratified in September 2016, the SD-PEX24055 NIC is also backwards-compatible with legacy 1000BASE-T Ethernet. The AQN-107 is a single-chip, single-port, high-performance PCIe 3.0 Multi-Gig 10GBASE-T/5GBASE-T/2.5GBASE-T/ 1000BASE-T/100BASE-TX Ethernet adapter. It incorporates Aquantia's AQrate PHY technology to deliver 10 GbE, 5 GbE and 2.5 GbE network connectivity speeds over 100 m with zero change required for legacy cabling. Speeds ranging from 5 GbE to 100 M are supported by Cat 5e cabling while 10GbE requires a minimum of Cat6 with Cat 6a running up to 100 m.
