Fervit 4 Port PCIe 4.0 X16 to Oculink Adapter

SKU CH-PPCG-886MB

Adds four OCuLink ports to a PCIe 4.0 x16 slot, enabling 64 Gbps links for GPUs or SSDs on motherboards that split PCIe lanes

  • PCIe 4.0 delivers 64 Gbps bandwidth for fast GPU and SSD links
  • Backward compatible with PCIe 3.0 and 2.0 motherboards
  • Four OCuLink ports connect multiple drives or expansion cards from one x16 slot
  • Requires motherboard with PCIe bifurcation to use all four ports
  • Includes 8 cm and 12 cm brackets for flexible chassis mounting

Four-Port PCIe 4.0 to OCuLink Adapter

This adapter converts a single PCIe 4.0 x16 slot into four OCuLink SFF-8611/8612 connectors. It targets builders who need to attach multiple SSDs, an eGPU or other expansion cards in compact hosts, desktops or laptops. Fixing holes allow secure mounting inside the chassis.

Upgrading from single-connector or PCIe 3.0 brackets

The card delivers up to 64 Gbps aggregate bandwidth and is backward compatible with PCIe 3.0 and 2.0 motherboards. The jump is worthwhile when the platform supports PCIe lane bifurcation; without split lanes the board will only recognise one attached drive. Systems lacking detachable PCIe channels cannot use all four ports.

OCuLink interface practical limits

Each port complies with SFF-8611 and SFF-8612 specifications and supports SAS-4 24 Gbps signalling. Cable length and signal integrity are governed by the OCuLink standard, so very long runs may reduce achievable throughput. The adapter occupies a standard x16 slot and includes 8 cm and 12 cm brackets for different chassis heights.

Questions about this item

What PCIe slot size and bracket options does the Fervit 4 Port adapter need to fit my case?

The card uses a PCIe 4.0 x16 edge connector and ships with 8 cm and 12 cm slot brackets, plus fixing holes for secure mounting.

How do I install the adapter so all four OCuLink ports are recognised by the motherboard?

Insert the card into a PCIe x16 slot on a motherboard that supports PCIe lane bifurcation; without bifurcation only the first port will be detected.

When should I replace the OCuLink cables connected to this adapter?

Replace cables if they show physical damage, intermittent link errors, or when upgrading to a newer SAS-4 24 Gbps or PCIe 4.0 64 Gbps standard that the existing cables do not support.
