ATTO dual-port 100GbE PCIe 3.0 x16 optical network card

ATTO Technology

ATTO Technology FFRMN312000 100GbE PCIe 3.0 x16 2-port optical network card

SKU CH-11PS-GHZYC MPN FFRMN312000

A 100GbE PCIe 3.0 x16 card with two optical ports supporting 100, 50, 40, 25 and 10GBase-X speeds

  • 100 GbE throughput over dual optical ports
  • PCIe 3.0 x16 interface for high-bandwidth connectivity
  • Supports 100G, 50G, 40G, 25G and 10G speeds
  • Two-port design enables link aggregation or redundancy
  • Optical fibre interfaces for long-distance data-centre links

High-density 100GbE connectivity

The ATTO FFRMN312000 is a dual-port 100GbE network interface card built for servers and workstations that need high-throughput optical links. It connects through a PCIe 3.0 x16 slot and supports link speeds of 10, 25, 40, 50 and 100GBase-X. The two optical fibre ports suit storage clusters, media workflows and HPC nodes.

Passive cooling for quiet racks

With no onboard fan the card relies on chassis airflow, keeping acoustic output at zero and eliminating a moving part that can fail. Power draw stays within the PCIe 3.0 x16 slot envelope, so no auxiliary connector is required. The design targets dense rack environments where thermal headroom and silence matter.

Dual-port density in one slot

A single x16 slot delivers two 100GbE optical interfaces, freeing expansion capacity for additional storage or compute cards. Compatible transceivers and fibre patch cables are needed to complete the links. It is not suited for builds limited to x8 electrical slots or copper-only infrastructure.

Questions about this item

How do I install the ATTO FFRMN312000 into a PCIe 3.0 x16 slot and what step is often missed?

Insert the card into a PCI Express 3.0 x16 slot, secure the bracket, then attach the optical fibres to the two ports; the step often missed is cleaning each connector with a lint-free wipe before mating to avoid signal loss.

What maintenance or replacement will the ATTO FFRMN312000 need over time?

The optical transceivers and fibre patch cords are the only replaceable items; inspect connectors for dust or damage periodically and swap transceivers if link errors rise.

Which limit appears first under sustained load on the ATTO FFRMN312000?

The PCI Express 3.0 x16 host interface sets the ceiling; sustained traffic above the bus capacity will saturate the slot before the dual 100 Gb/s optical ports reach their maximum rate.
