The MCIO 8X to 2x MCIO 4X cable VTC-AMSEF0010005-K2 from فيتالكون is a high-performance splitter cable engineered for PCIe Gen 5 server and data center applications. It takes a single MCIO 8X (8-lane) connector on the host side and splits the signals into two independent MCIO 4X (4-lane) outputs, allowing one motherboard port to drive two downstream devices such as NVMe SSDs, retimer cards, or expansion backplanes. The MCIO 8X to 2x MCIO 4X cable supports data rates up to 32 GT/s per lane, delivering aggregate bandwidth of up to 64 GB/s across both channels.

Constructed with 30 AWG high-frequency twin-axial conductors and an 85 ohm controlled-impedance system, the MCIO 8X to 2x MCIO 4X cable preserves signal integrity at PCIe Gen 5 speeds. The compact MCIO connector form factor, compliant with the SFF-TA-1016 style interface, maximizes front-panel port density in dense server racks. Robust shielding minimizes crosstalk and EMI, ensuring reliable data transmission even in electrically noisy environments. The cable’s durable construction withstands repeated mating cycles, making it suitable for both production deployments and field-serviceable configurations.

VITALCONN offers standard lengths from stock as well as OEM/ODM custom lengths to suit specific rack and chassis routing requirements. The MCIO 8X to 2x MCIO 4X cable is fully compatible with PCIe Gen 5 and is backward-compatible with PCIe Gen 4 and Gen 3 MCIO interfaces.

Frequently Asked Questions

What PCIe generation does the MCIO 8X to 2x MCIO 4X cable support?

The MCIO 8X to 2x MCIO 4X cable is designed for PCIe Gen 5 at 32 GT/s per lane and is fully backward compatible with PCIe Gen 4 (16 GT/s) and Gen 3 (8 GT/s) MCIO interfaces, ensuring flexibility across server generations.

How does the 1-to-2 splitter work electrically?

The MCIO 8X connector carries 8 differential lanes. This cable routes 4 lanes to each MCIO 4X output, creating two independent x4 PCIe links from a single x8 host port. No active components are required; the split is purely passive.

Can I order custom cable lengths for my server chassis?

Yes. VITALCONN offers OEM/ODM custom lengths tailored to your rack and chassis routing. Contact us with your required length and quantity for a quote.

What impedance and wire gauge does this cable use?

The MCIO 8X to 2x MCIO 4X cable uses 30 AWG twin-axial conductors with 85 ohm controlled differential impedance, matching the MCIO and PCIe Gen 5 signal-integrity requirements.
