1000Base-SX PCIe 2.1 x4 network card

This Axiom adapter provides a single 1000Base-SX fibre port for Gigabit Ethernet connectivity. It targets servers and workstations that need reliable fibre uplinks in enterprise or data-centre environments.

PCI Express 2.1 x4 installation profile

The card fits a standard PCIe x4 or larger slot and uses a low-profile bracket for dense chassis. Fibre polarity must be matched at both ends, and the link will not come up if the SFP transceiver is absent or mismatched.

Sustained throughput on fibre

The 1000Base-SX link maintains line-rate Gigabit performance over extended transfers without the thermal throttling seen on some copper PHYs. Enterprise drivers keep latency stable under continuous high-transaction workloads.

Questions about this item

How can I verify the Axiom 1000Base-SX card is working after installing it in a PCI Express 2.1 x4 slot?

Check the link LED on the 1000Base-SX connector and confirm the operating system detects a 1000 Mbps fibre link in the network adapter settings.

What comes in the box with the Axiom Intel Gigabit Ethernet Card and what must I buy separately?

The card itself is supplied; you will need to purchase compatible 1000Base-SX fibre patch cables and SFP transceivers separately.

Which Axiom 1000Base-SX PCI Express 2.1 x4 version should I choose for a server needing Gigabit fibre connectivity?

This single-port 1000Base-SX model on a PCI Express 2.1 x4 interface is the version designed for Gigabit fibre uplinks.
