SMUGDESK X520-SR1 10G SFP+ Fiber NIC Intel 82599 with 300m Multi-Mode Module

SKU CH-Q88Y-P9KTR

PCIe 2.0 x8 single-port 10GbE fiber NIC with Intel 82599 controller, pre-installed 300m multi-mode module and low-profile bracket for server or NAS

  • Intel 82599 controller delivers 10 Gbps throughput over a single SFP+ port
  • Pre-installed 10G SR multi-mode transceiver enables 300 m reach on OM3 fiber
  • PCIe 2.0 x8 interface fits x8 and x16 slots with both full-height and low-profile brackets
  • SR-IOV, VMDq, TCP/UDP offload, LACP and 9000 MTU jumbo frames reduce CPU load
  • Passive heatsink ensures stable 24/7 operation across Windows Server, Linux and VMware ESXi

Single-port 10 GbE fiber NIC for servers

The SMUGDESK X520-SR1 is a PCIe 2.0 x8 network card built around the Intel 82599 controller. It ships with a pre-installed 10G multi-mode SFP+ transceiver ready for OM3 fiber runs up to 300m. Full-height and low-profile brackets are included so the card fits standard or 2U rack servers.

Suits virtualised hosts needing one 10 GbE link

This card targets storage servers, NAS aggregation points and VMware ESXi hosts that need a single high-speed fiber connection. Features such as SR-IOV, VMDq, TCP/UDP offload, LACP and 9000MTU jumbo frames reduce CPU load in virtualised workloads. It is not for deployments that require multiple 10 GbE ports from a single slot.

PCIe 2.0 x8 slot requirement decides fit

The card needs an available PCIe 2.0 x8 or x16 slot on the motherboard. If the target system only offers x4 or x1 slots, the card will not operate at its rated 10Gbps throughput. Verify the slot width before purchase.

Questions about this item

Does the X520-SR1 card require a PCIe 2.0 x8 or x16 slot on the motherboard to operate?

Yes, the card installs in a PCIe 2.0 x8 slot and is compatible with x8 or x16 motherboard slots for full bandwidth.

Will the included multi-mode module work with existing OM3 fiber cabling for a 300m link?

The pre-installed SR module supports OM3 multi-mode fiber up to 300 metres, matching your current cable plant.

How can I verify the 10G link and jumbo frames are active after installing the Intel 82599 NIC?

Confirm the link negotiates at 10Gbps in the OS network settings and test throughput with a 9000 MTU ping across the connection.
