Oculink 4i Male-to-Female Extension Cable

This passive cable extends an internal PCIe 4.0 x4 link between an SFF-8611 male port and an SFF-8612 female port. It uses copper conductors with gold-plated contacts and EMI shielding to maintain signal integrity up to 64Gbps theoretical bandwidth. The 19-inch length suits tight chassis routing in compatible servers and workstations. No drivers or active electronics are required.

Suitable For PCIe 4.0 x4 Storage And GPU Expansion

Builders adding NVMe backplanes, HBA cards or GPU adapter cards that use the Oculink 4i interface can use this cable to bridge longer internal distances. It does not convert protocols, so systems without native SFF-8611 or SFF-8612 ports cannot use it directly. Buyers needing active signal retiming or protocol conversion should look at a different solution.

Fits Standard Internal PCIe Routing Paths

The cable connects directly to compatible host adapters, backplanes or riser cards that present the correct 42-pin Oculink interfaces. Its passive design frees up a PCIe slot that might otherwise be occupied by an active extender card. Verify lane support, connector direction and clearance inside your chassis before installation.

Questions about this item

What existing Oculink SFF-8611 4i male port or cable must I already have to plug this 19-inch female SFF-8612 end into?

You need a compatible host, adapter card, backplane or device that presents an SFF-8611 4i male interface so the cable's female SFF-8612 connector can mate with it.

Will this passive extension work with a PCIe 3.0 x4 HBA card and backplane I plan to keep?

Yes, the cable is passive and carries PCIe 4.0 x4 signaling up to 64Gbps; it will operate at PCIe 3.0 speeds when connected to 3.0 endpoints.

How can I confirm the link is running at PCIe 4.0 x4 after I route the cable inside the chassis?

Check the host or adapter card firmware, OS device manager or BIOS/UEFI to verify the negotiated link width shows x4 and speed shows 4.0.
