EXSYS Quad 5 Gigabit Ethernet PCIe x4 Card (Realtek RTL8126) EX-60154

Quad-port 5 Gigabit Ethernet PCIe x4 network adapter delivering up to 5 Gbps per port for high-speed wired connectivity. Powered by the Realtek RTL8126 chipset, it provides four RJ45 ports with backward compatibility to 2.5GbE, 1GbE, and 100MbE, making it ideal for upgrading workstations and servers to multi-gigabit speeds.

Advantages

Four independent 5GbE ports enable link aggregation, network segmentation, or dedicated connections for multiple devices. The PCIe 3.0 x4 host interface ensures sufficient bandwidth for all ports operating simultaneously. Support for jumbo frames up to 16KB, VLAN tagging (IEEE 802.1Q), and checksum offload reduces CPU overhead and enhances throughput in demanding environments.

Suitable for

• High-performance workstations requiring fast file transfers and low-latency networking.
• Servers and NAS systems needing multiple multi-gigabit Ethernet connections.
• Virtualization hosts where dedicated NICs per VM improve network isolation.
• Small business networks upgrading to 5GbE infrastructure.
