The MCIO 4X to MCIO 4X cable VTC-AMSFF0010004-K2 from VITALCONN provides a direct PCIe Gen5 interconnect between two MCIO 4X ports. MCIO (Multi-Channel I/O, the SFF-TA-1016 standard adopted by OCP platforms) has become the default sideband-free attach for NVMe drives, smart NICs, and FPGA cards in modern servers. With straight (vertical-exit) connectors on both ends, this cable links a motherboard MCIO header to a drive backplane or expansion card along the shortest possible path, sustaining 32 GT/s per lane across all 4 lanes of each connector.
Each differential pair in the MCIO 4X to MCIO 4X cable uses 30 AWG high-frequency copper with impedance controlled to 85 ± 5 Ω, keeping insertion loss and crosstalk comfortably inside PCIe Gen5 budgets over in-chassis distances. The shielded twin-axial construction plus ruggedized connector shells delivers the signal integrity that enterprise storage arrays and AI servers demand, run after run, in 24/7 data center operation.
Standard lengths of 0.5 m, 0.8 m, and 1.0 m cover typical server layouts, and OEM custom lengths are produced to order. The cable is part of the VITALCONN High Speed Cable family — explore the full range of MCIO, SlimSAS, OCuLink, and PCIe interconnects for your platform.

Key Features
- PCIe Gen5 throughput: 32 GT/s per lane over 4 lanes gives roughly 16 GB/s per direction for NVMe storage and accelerator traffic with low latency.
- High-density MCIO interface: the compact SFF-TA-1016 form factor saves PCB area compared with legacy PCIe slots — learn more at the SFF Committee.
- Straight-to-straight geometry: vertical-exit connectors at both ends of the MCIO 4X to MCIO 4X cable keep routing predictable in standard ATX and server chassis.
- Precision 85 Ω impedance: tightly controlled differential pairs minimize reflections and preserve eye margin at Gen5 rates.
- Durable construction: ruggedized connector shells with positive latching withstand repeated service insertion cycles in enterprise racks.
- Effective EMI shielding: foil-and-braid shielding maintains stable transfer even in cable-dense enclosures.
- Custom lengths: OEM builds match your exact interconnect distance, eliminating excess cable slack and improving airflow.
- Scalability: supports future PCIe Gen5 platform upgrades without recabling, protecting system designs across generations.

Frequently Asked Questions
Q1: What PCIe generation does this MCIO 4X to MCIO 4X cable support?
A1: It is designed for PCIe Gen5 at 32 GT/s per lane and is also suitable for Gen4 and Gen3 links in mixed-generation deployments.
Q2: What is the difference between this cable and the 90-degree version?
A2: This cable has straight (vertical-exit) connectors on both ends; the right-angle version (VTC-AMSFF0110001-K2) routes the cable parallel to the board for low-clearance chassis.
Q3: What does VTC-…-K2 mean in the part number?
A3: VTC is the VITALCONN product prefix and K2 is the platform suffix. Quote VTC-AMSFF0010004-K2 for samples, drawings, and OEM pricing of this MCIO 4X to MCIO 4X cable.
Q4: Can I order custom lengths?
A4: Yes. Beyond the standard 0.5 m / 0.8 m / 1.0 m lengths, OEM custom lengths are manufactured to your chassis specification.
