The MCIO 8X to 2x OCuLink SFF-8611 cable VTC-AMSE80010001-K2 from バイタルコン is a high-performance splitter cable designed for PCIe Gen 4 server and storage applications. It takes a single MCIO 8X (8-lane) connector on the host side and splits the signals into two OCuLink SFF-8611 connectors, each carrying 4 lanes. This configuration allows one motherboard MCIO port to connect to two NVMe SSDs, storage backplanes, or expansion devices simultaneously. The MCIO 8X to 2x OCuLink SFF-8611 cable supports data rates up to 16 GT/s per lane, delivering up to 32 GB/s of aggregate bandwidth across both OCuLink outputs.

Constructed with 30 AWG high-frequency twin-axial conductors and an 85 ohm controlled-impedance system, the MCIO 8X to 2x OCuLink SFF-8611 cable preserves signal integrity at PCIe Gen 4 speeds. The OCuLink SFF-8611 connector is a compact, high-density interface defined by the SFF committee, optimized for NVMe storage connectivity in server backplanes and storage arrays. The MCIO 8X connector follows the SFF-TA-1016 style interface, maximizing port density on server front panels. Full EMI shielding with drain wire suppresses crosstalk and external interference, while robust connector housings ensure long-term reliability through repeated mating cycles.

VITALCONN provides standard cable lengths from stock as well as OEM/ODM custom lengths for specific chassis routing needs. The MCIO 8X to 2x OCuLink SFF-8611 cable is fully compatible with PCIe Gen 4 and is backward compatible with PCIe Gen 3. Review the SFF committee specifications for connector and signal-integrity details, and explore the full High Speed Cable range at VITALCONN for all your server interconnect requirements.
