Full-height PCIe card with dual SFP+ ports and two transceivers installed

SMUGDESK

SMUGDESK X520-LR2 10GbE Dual SFP+ 10km LR network card

SKU CH-Q4Q3-PJ40R

Dual-port 10GbE fiber card with Intel 82599 controller, two pre-installed 10km LR SFP+ modules, PCIe 2.0 x8, SR-IOV, iSCSI offload and 9000MTU jumbo frames

  • Intel 82599 controller powers two independent 10Gbps SFP+ ports
  • Pre-installed LR single-mode transceivers enable 10km fiber links
  • PCIe 2.0 x8 interface fits x8 or x16 slots with both brackets included
  • Hardware offload and 9000MTU jumbo frames reduce server CPU load
  • Passive heatsink supports continuous 24/7 enterprise operation

10km dual-port fiber kit

The SMUGDESK X520-LR2 delivers two 10GbE SFP+ ports with pre-installed single-mode LR transceivers rated for 10km links. It targets administrators who need a ready-to-run long-haul uplink for NAS clusters, virtualisation hosts or inter-building data-centre connections without sourcing optics separately.

PCIe 2.0 x8 electrical interface

The card operates on a PCIe 2.0 x8 bus and fits x8 or x16 slots, so the host platform must provide that electrical width for full 10Gbps per-port throughput. Systems limited to x4 or x1 electrical links will throttle bandwidth and are not a fit for this adapter.

Brackets and open SFP+ cages

Both full-height and low-profile brackets ship in the box, letting the same card move between standard racks and 2U chassis. The cages accept optional SR multimode modules or DAC copper cables, so the hardware can be repurposed for shorter runs without buying a new adapter.

Questions about this item

What does the 10 Gbps per port rating mean for real-world throughput?

Each SFP+ port delivers a full 10 Gbps line rate; with two ports active the card can push 20 Gbps aggregate through the PCIe 2.0 x8 interface.

What does the PCIe 2.0 x8 interface cap in practice?

The PCIe 2.0 x8 slot provides 16 Gbps of bus bandwidth, which is sufficient for both 10 Gbps ports at full line rate.

What brackets and slot height does the card need to fit?

Both full-height and low-profile brackets are included so the card fits standard rack servers and 2U slim chassis.
