Using 2.5G network card chip, it has low power consumption, low latency, more stable transmission, and is not easy to cause packet loss and distortion.The PCIe to 2.5G network adapter supports data transfer rates up to 2.5 Gbps. Combined with the new 2.5GBase-T technology, it is 2.5 than typical Gigabit adapters.The 2.5G network adapter supports three speeds: 2.5Gbps, 1Gbps and 100Mbps.Fits any PCI x1, x4, x8 or x16 slot.The 2.5G network adapter supports , 19.04 or later operating .PCI 3.1: 5GT/s supports x1 width ().Supports PCI x1, x4, x8 or x16 slots.Integrated /PHY supports 10BASE-Te, 100BASE-TX, 1000BASE-T and 2500BASE-T 802.3 specifications.RJ45 connection: Use CAT5e, CAT6 or CAT6A compatible cables up to 100 .IEEE 802.3 auto-negotiationIEEE 802.3x and IEEE 802.3z compliant control support with software controllable thresholds and Tx pause framesMulti-queue: 4 Tx and queues per deviceTx/ IP, SCTP, and UDP checksum offload (IPv4 IPv6) capabilitiesEnergy Efficient Ethernet (EEE): IEEE 802.3az enabled to reduce power consumption, supports 10GBASE-Te (EEE at 10Mbps).
