Single-port 10 Gbps SFP+ network adapter installs in a PCIe 2.0 x4 slot
This Axiom network adapter adds a single 10 Gbps SFP+ port through a PCI Express 2.0 x4 slot. It is built for servers and workstations that need a straightforward 10 Gigabit Ethernet uplink. The plug-in card format fits standard expansion bays without requiring proprietary brackets.
Administrators who need one 10 Gbps link for storage access or backbone connections will find this card matches that requirement. Builders who need multiple ports, link aggregation, or fibre transceivers included should look at other options because this model provides only a single SFP+ cage.
The card communicates with the system over a PCIe 2.0 x4 connection, so the slot must supply that exact electrical width. If the available slot is only x1 or x8 wired as x4 electrically, the adapter will not negotiate its full 10 Gbps rate. Confirm the motherboard or riser delivers a true x4 link before purchasing.

No published specifications for this item yet.
Power off the system, insert the card firmly into an available PCI Express 2.0 x4 slot, secure the bracket screw, then insert a compatible SFP+ transceiver into the port before connecting the fibre or copper cable.
The adapter itself has no moving parts; only the SFP+ transceiver or the patch cable may need replacement if damaged or if you change link distance or media type.
The PCI Express 2.0 x4 host interface caps sustained throughput at the bus level, so the slot bandwidth is the first ceiling you will reach under constant load.
