Intel X520-SR2 10GBase-SR Dual-Port PCIe x8 Network Card

SKU CH-SQYB-SPEBC

Dual-port 10GBase-SR adapter with PCIe x8 interface for optical fibre networking

  • Dual 10GbE ports deliver high-throughput fibre connectivity
  • PCI Express x8 host interface enables full 10GbE line rate
  • Low-profile and full-height brackets fit diverse chassis
  • RoHS compliance confirms restricted-substance adherence
  • Optical fibre media support suits short-range data-centre links

Dual-port 10GBase-SR adapter

The Intel X520-SR2 is a dual-port 10GBase-SR network card that installs in a PCI Express x8 slot. It uses optical fibre media and supports a low-profile or full-height bracket. The card is supplied in bulk packaging and carries RoHS compliance.

Fibre environments needing two 10 Gb links

This card suits servers or workstations that require two 10 Gb optical connections over short-range multimode fibre. It is not for installations that only have copper cabling or that lack an available PCI Express x8 electrical connection.

PCI Express x8 host interface

The host interface is PCI Express x8, which determines whether the card fits the target system. Verify that the motherboard or riser provides an x8 electrical link before purchasing.

Questions about this item

How can I verify the X520-SR2 is operating at 10GBase-SR speed after installation?

Check the link status LEDs on each port; a steady green light indicates an active 10 Gbps optical connection, while the OS network adapter properties will report a 10 Gbps link speed.

What is included with the bulk-packaged Intel X520-SR2 and what must be sourced separately?

The bulk package contains only the dual-port PCIe x8 adapter; you will need to purchase compatible SFP+ SR transceivers and LC duplex multimode fibre patch cables separately.

Which version of the X520 series should I choose for a PCIe x8 slot with two fibre ports?

The X520-SR2 is the specific model that provides two 10GBase-SR optical ports on a PCI Express x8 interface, matching your slot and media requirements.
