The MCIO 8X to 2x Mini SAS HD SFF-8643 cable VTC-AMSE30010001-K2 from VITALCONN is a high-performance splitter cable engineered for PCIe Gen 4 and SAS 3.0 server and storage applications. It takes a single MCIO 8X (8-lane) connector on the host side and splits the signals into two Mini SAS HD SFF-8643 connectors, each carrying 4 lanes. This enables one motherboard MCIO port to drive two downstream SAS or NVMe storage devices, backplanes, or expansion cards. The MCIO 8X to 2x Mini SAS HD SFF-8643 cable supports data rates up to 16 GT/s per lane for PCIe Gen 4 and 12 Gb/s per lane for SAS 3.0, delivering up to 32 GB/s of aggregate bandwidth across both SFF-8643 outputs.
Built with 30 AWG high-frequency twin-axial conductors and an 85 ohm controlled-impedance system, the MCIO 8X to 2x Mini SAS HD SFF-8643 cable preserves signal integrity at high data rates. The Mini SAS HD SFF-8643 connector is a compact, high-density interface defined by the SFF committee, widely used in enterprise storage arrays and server backplanes. The MCIO 8X connector follows the SFF-TA-1016 style interface, enabling greater front-panel port density than legacy PCIe connectors. Full EMI shielding with drain wire suppresses crosstalk and external interference, while robust connector construction supports repeated mating cycles for long-term reliability.
VITALCONN offers standard cable lengths from stock and OEM/ODM custom lengths for specific rack and chassis routing requirements. The MCIO 8X to 2x Mini SAS HD SFF-8643 cable is compatible with both PCIe Gen 4 and SAS 3.0 protocols, making it versatile across storage and computing topologies.
