Graviton PCIe X4 Gigabit Fiber Card Single Mode 1310nm 10km LC Optical Transceiver Module

SKU CH-9J4Y-EY89K

A PCIe x4 Gigabit fiber card with a single-mode 1310 nm transceiver for 10 km links and an Intel 82576 controller

  • Gigabit fibre link over 10 km single-mode
  • PCI Express x4 host interface with Intel 82576EB controller
  • 16 transmit and receive queues plus RSS cut CPU load
  • VMDq virtualisation support with eight queue pools per port
  • Dual-band 2.4 GHz and 5 GHz wireless at 600 Mbps

PCIe X4 Gigabit Fiber Card

The Graviton PCIe X4 Gigabit Fiber Card provides a single SFP LC port for single-mode fibre at 1310 nm. It connects servers to Gigabit Ethernet networks over distances up to 10 km. The card uses the JL82576EB chipset and supports BOOT ROM, WoL, PXE and iSCSI boot for remote deployment. Management includes IPMI pass-through via SMBus or NC-SI and VLAN filtering.

Single-mode 10 km distance limit

Single-mode fibre at 1310 nm reaches 10 km, so links beyond that range need different optics or repeaters. The PCIe X4 host interface supplies ample bandwidth for the 1000 Mbps line rate. The onboard transceiver is fixed to single-mode; multi-mode fibre cannot be used with this module. Buyers needing longer reach or multi-mode compatibility must select a different transceiver.

Upgrades copper Gigabit NICs

This card replaces copper-based Gigabit adapters when cable runs exceed 100 metres or electromagnetic immunity is required. The 16 transmit and receive queues per port plus 16 RSS queues reduce CPU load on multi-core servers. Eight VMDq pools improve virtual machine networking density. The jump is worth it for server rooms that need 10 km fibre links with hardware offload features.

Questions about this item

Should I choose the single-mode 1310 nm module for my 10 km link?

Yes — the card includes a single-mode 1310 nm transceiver rated for 10 km over LC fibre.

What does the 1000 Mbps rate deliver in a live server?

It provides a full 1000 Mbps Gigabit Ethernet link with 16 transmit and 16 receive queues plus RSS to spread load across CPU cores.

How does the PCIe x4 interface affect throughput?

The x4 bus gives ample headroom for the 1000 Mbps line rate and supports advanced features such as VMDq and direct cache access.
