The MCIO 4X to OCuLink SFF-8611 cable VTC-AMSF80010001-K2 from VITALCONN bridges two of the most widely deployed PCIe cable interfaces in modern storage and server platforms. The MCIO 4X end attaches to motherboard or controller headers built to the SFF-TA-1016 style interface common on OCP and AI server boards; the OCuLink SFF-8611 end connects to NVMe backplanes, drive adapters, and expansion devices that use the compact 8611 connector. The combined 4-lane path carries PCIe 4.0 traffic at 16 GT/s per lane for roughly 8 GB/s per direction of storage bandwidth.
The MCIO 4X to OCuLink SFF-8611 cable is constructed with 30 AWG high-frequency copper twin-axial pairs, differential impedance controlled to 85 ± 5 Ω, and foil-plus-braid shielding on every pair. This keeps crosstalk and EMI well within PCIe 4.0 margins in cable-dense server interiors, and the compact connector envelopes free up board area compared with legacy slot-based attach. Both connectors feature positive latching for secure, service-friendly mating in racks.
Standard lengths of 0.5 m, 0.8 m, and 1.0 m are available from stock, with OEM custom lengths produced to order. Explore the complete High Speed Cable range — MCIO, OCuLink, SlimSAS, Mini SAS, and PCIe variants — for every interconnect position in your platform.
