PCIe 4.0 Oculink cable for server builds

This 50 cm Vszerda cable connects two SFF-8611 8i ports with a PCIe 4.0 link running at 16 GT/s across eight lanes. It suits technicians upgrading backplanes or adding NVMe adapters in rackmount and workstation chassis. The male-to-male connectors are straight, so cable routing stays predictable in dense enclosures.

Bandwidth ceiling and backward limits

The link tops out at 16 GT/s per lane, which is the PCIe 4.0 maximum; it will not reach PCIe 5.0 speeds. The cable is backward compatible with 3.0, 2.0 and 1.0 hosts, so older backplanes still work but run at their native rates. Length is fixed at 50 cm, so runs longer than 1.6 feet need a different cable.

Braided jacket and straight connectors

A protective braided exterior resists snagging and abrasion during repeated insertions in tight server bays. Straight SFF-8611 8i plugs keep the profile low, helping airflow and cable management in 1U or 2U trays. The compact design targets builders who need reliable density without excess slack.

Questions about this item

Should I choose the 50 cm length or a longer Oculink cable for my server build?

The 50 cm cable suits tight chassis runs between a backplane and an NVMe adapter; longer cables add latency and signal loss at PCIe 4.0 speeds.

What does the 16 GT/s rate mean for real-world NVMe throughput?

Each of the eight lanes runs at 16 GT/s, giving the raw link speed PCIe 4.0 defines; actual throughput depends on the drives and controller used.

The cable uses SFF-8611 8i connectors — what does that cap in practice?

SFF-8611 8i carries eight PCIe lanes, so the link tops out at PCIe 4.0 x8 bandwidth and is backward compatible with PCIe 3.0, 2.0 and 1.0 devices.
