Frequently Asked Questions

What is the difference between SFP+ and RJ45 NICs?

SFP+ NICs use fiber optic or DAC cables and support 10G over longer distances (up to 10km with fiber). RJ45 NICs use standard Ethernet cables (Cat6A required for 10G) and are limited to ~100m. Choose SFP+ for data center switch connections and RJ45 for existing copper infrastructure.

What is an OCP NIC?

OCP (Open Compute Project) is a standardized mezzanine NIC form factor used in Dell, HPE, and Lenovo servers. OCP 3.0 NICs plug into a dedicated slot on the motherboard, saving a PCIe slot. Dell calls them NDC (Network Daughter Card), HPE calls them OCP adapters.
