The MCIO 16X to 2x MCIO 8X cable VTC-AMSKE0010001-K2 from فيتالكون is a passive bifurcation cable that splits a single MCIO 16X (16-lane) host port into two independent MCIO 8X (8-lane) links. Working with the PCIe bifurcation capability of the CPU or PCIe switch, the MCIO 16X to 2x MCIO 8X cable lets one x16 port drive two x8 devices such as NVMe SSDs, GPUs, or network adapters at up to 32 GT/s per lane. The two branches are electrically isolated, so each attached device enjoys a dedicated x8 link without interference from the other channel group.

At the fan-out point, the internal construction is precision-engineered for impedance continuity, holding 85 ohm +/- 10% through the split so that reflections do not disturb Gen 5 signaling. Dedicated shielding isolates the two 8-lane channel groups from near-end crosstalk, and branch lengths are matched to keep multi-lane timing aligned. All three connectors – the 74-pin MCIO 16X main plug and the two MCIO 8X fan-out plugs – carry positive latches rated for 200+ mating cycles, and 30 AWG twin-axial conductors balance attenuation against routing flexibility.

VITALCONN offers the MCIO 16X to 2x MCIO 8X cable in typical lengths from 0.3 m to 0.8 m, with OEM/ODM custom lengths, labels, and packaging on request.

Frequently Asked Questions

Does the MCIO 16X to 2x MCIO 8X cable require active electronics?

No. The MCIO 16X to 2x MCIO 8X cable is fully passive. It routes 8 of the 16 differential lane pairs to each MCIO 8X plug; the actual split is enabled by the PCIe bifurcation function of the host CPU or switch (typically configured as x8/x8).

What data rate does the cable support?

The cable supports up to 32 GT/s per lane for PCIe Gen 5 and is backward compatible with Gen 4 and Gen 3. Premium designs extend to 64 GT/s using PCIe 6.0 PAM4 signaling.

What connector pin counts are involved?

The main end uses a 74-pin MCIO 16X plug carrying 16 PCIe lanes, while each fan-out end uses an MCIO 8X plug (38 or 40 pin depending on pinout) carrying 8 lanes.

Can I get custom lengths or other split ratios?

Yes. VITALCONN provides OEM/ODM custom lengths for the standard x16 to 2x x8 split, and other configurations can be discussed. Contact us with your requirements for a quotation.
