PCIe X16 to 2x SlimSAS SFF-8654 8i Cable – VTC-APEBEOP30001-K2

The VITALCONN VTC-APEBEOP30001-K2 is a PCIe X16 to 2x SlimSAS SFF-8654 8i splitter cable that divides a single x16 host port into two independent x8 links. Supports PCIe 4.0 at 16 GT/s per lane with 30 AWG high-frequency copper conductors and 85 ohm controlled impedance. Ideal for NVMe storage expansion, GPU enclosures, and disaggregated compute-storage architectures.

The PCIe X16 to 2x SlimSAS SFF-8654 8i cable VTC-APEBEOP30001-K2 from فيتالكون splits a single PCIe x16 host slot into two independent SlimSAS SFF-8654 8i ports, each carrying 8 PCIe lanes. One end of the cable terminates to a gold-finger PCIe x16 edge-card plug that seats directly in a motherboard or riser slot; the other end fans out to two latching SFF-8654 8i connectors that attach to NVMe drive enclosures, add-in cards, or GPU expansion boxes. Each branch sustains the full PCIe 4.0 rate of 16 GT/s per lane, delivering 16 GB/s of usable bandwidth per port for storage and compute traffic.

Engineered for loss budgets typical of server backplanes, the PCIe X16 to 2x SlimSAS SFF-8654 8i cable is built on 30 AWG high-frequency copper twin-axial conductors with 85 ± 5 Ω differential impedance. The dual shielding scheme — per-pair aluminum foil plus an overall braided wrap — keeps crosstalk and EMI well inside PCIe 4.0 margins even when the two branches are dressed through dense chassis harnesses. Straight-on connectors at both ends simplify routing in 1U and 2U systems where vertical clearance is limited.

Mating durability is rated at 250+ insertion cycles, and the cable is downward compatible with PCIe 3.0/2.0/1.0 hosts and devices. Browse the complete High Speed Cable portfolio on our site, or request OEM custom lengths built to your exact chassis dimension.

Key Features

Dual SFF-8654 8i outputs: a single x16 slot drives two independent x8 devices — ideal for NVMe storage and GPU expansion without occupying extra slots.
PCIe 4.0 ready: 16 GT/s per lane with generous eye margin, and full backward compatibility with PCIe 3.0/2.0/1.0 platforms.
High-frequency copper: premium conductor material lowers attenuation and crosstalk to preserve signal integrity across the full run.
85 Ω impedance control: differential pairs tuned to the PCI-SIG specification minimize reflections at 16 GT/s.
Straight-on connector design: straight headers at both ends of the PCIe X16 to 2x SlimSAS SFF-8654 8i cable make cable dressing simple in compact server and workstation interiors.
250+ mating cycles: ruggedized contacts rated for repeated service access in data center racks.
OEM custom lengths: built to your chassis drawing so branches arrive pre-cut, labeled, and terminated.
Quality assurance: every cable is factory-tested for continuity, impedance, and link training before shipment under our ISO 9000 quality system.

PCIe X16 to 2x SlimSAS SFF-8654 8i Cable Applications

HPC and AI servers: fan out a spare x16 slot to dual NVMe drive groups or accelerator cards in the same rack unit.
GPU expansion boxes / eGPU: connect external graphics enclosures to workstation motherboards over one tidy cable set.
Data center PCIe extension and splitting: disaggregate PCIe devices from compute boards in modular server architectures.
Disaggregated storage-compute systems: attach JBOD-style NVMe backplanes to host CPUs without dedicated switch silicon.
Graphics workstations and custom servers: add high-bandwidth devices where slot real estate is scarce.

Frequently Asked Questions

Q1: Does the PCIe X16 to 2x SlimSAS SFF-8654 8i cable require bifurcation support?
A1: Yes. The host CPU or motherboard must support x16 bifurcation into 2x x8 (a BIOS setting on most server platforms). No extra switch chip is needed.

Q2: Can each SFF-8654 8i branch run at full PCIe 4.0 speed?
A2: Yes. Each branch carries 8 lanes at 16 GT/s (16 GB/s per direction), provided both host and endpoint are PCIe 4.0 capable.

Q3: What does the VTC-…-K2 part number mean?
A3: VTC is the VITALCONN prefix and K2 the platform suffix. Quote VTC-APEBEOP30001-K2 when requesting samples, drawings, or OEM pricing for this PCIe X16 to 2x SlimSAS SFF-8654 8i cable.

Q4: Are custom lengths and labels available?
A4: Yes. Cables are manufactured to order in custom lengths with optional customer-specific wire marking, connector colors, and packaging.
