This passive copper twinax cable connects two MCIO 4i ports—ideal for extending or linking RAID/HBA cards, NVMe backplanes, and server modules. Slim, flexible construction eases routing while shielding maintains signal integrity. Supports PCIe Gen5 and is backward compatible with Gen4/Gen3; also suitable for other SFF‑TA‑1016 high‑speed protocols when supported by host/device. Data interconnect only; no protocol conversion or power delivery.
