Vszerda PCIe 5.0 MCIO x8 to Oculink SFF-8611 4i Cable 80 cm

SKU CH-5YZ3-BB0N3

Connects MCIO x8 to dual Oculink SFF-8611 4i ports for PCIe 5.0 links limited to PCIe 4.0 x4 per end, 80 cm length

  • PCIe 5.0 design supports 32 GT/s per lane
  • Dual Oculink SFF-8611 4i ports expand server connectivity
  • Secure connectors prevent vibration disconnection in data centres
  • Backward compatible with PCIe 4.0, 3.0, 2.0, 1.0
  • Premium materials maintain performance through continuous operation

PCIe 5.0 MCIO x8 to Oculink 4i

This 80 cm cable connects a PCIe 5.0 MCIO x8 port to two Oculink SFF-8611 4i connectors. It is built for server and workstation builders who need to link external storage enclosures or add-in cards to an internal MCIO header. The dual 4i breakout doubles the number of devices a single x8 lane group can serve.

Speed headroom and lane limits

Each lane is rated for 32 GT/s under the PCIe 5.0 specification, yet the Oculink SFF-8611 4i ends cap throughput at PCIe 4.0 x4 per connector. The cable therefore delivers full x8 bandwidth only when both 4i ports are used together; a single 4i device will not saturate the upstream x8 link. Backward compatibility covers PCIe 4.0, 3.0, 2.0 and 1.0 without reconfiguration.

Thermals and power in normal use

Passive copper construction adds no active cooling requirement and draws no auxiliary power. The shielded assembly resists signal degradation from electromagnetic interference in dense chassis, while the locking connectors prevent vibration-induced disconnects. No fan noise or thermal load is introduced beyond the negligible resistive loss of the conductors themselves.

Questions about this item

Will the 80 cm MCIO x8 cable work with my PCIe 4.0 or 3.0 backplane?

The cable is backward compatible with PCIe 4.0, 3.0, 2.0 and 1.0, so it will function with older backplanes at their native speeds.

How can I verify the dual Oculink SFF-8611 4i links are running at PCIe 4.0 x4 after installation?

Check the negotiated link speed in your OS or BIOS; each SFF-8611 4i port should report PCIe 4.0 x4 when the cable is seated correctly.

Does the package include both SFF-8611 4i connectors or must I buy the second one separately?

The single cable assembly provides one MCIO x8 plug that splits to two SFF-8611 4i connectors, so nothing extra is required.
