Overview
Our MCIO 8X to Dual Mini‑SAS HD SFF‑8643 NVLink expansion cable belongs to our Internal Connection SAS Cables Serie, purpose‑built for high‑density AI GPU training clusters, high‑performance servers and data center internal interconnection.
This custom NVLink breakout cable converts one MCIO 8X port into two Mini‑SAS HD SFF‑8643 interfaces, delivering stable high‑bandwidth data transmission between graphics cards, motherboards and storage controllers. As a factory‑direct server wiring harness supplier, we also provide a full lineup of internal SAS cables including MCIO 4X, Oculink SFF‑8611, SlimSAS SFF‑8654, Mini SAS SFF‑8087 and SATA internal cables to meet diverse rack‑mount server wiring demands.
Product Specifications
✅Conductor: HF copper, 30AWG
✅PCB contact plating: Gold 30u
✅Transmission rate: 25GT/s‑32GT/s
✅Supported protocol: PCIe Gen5, UPI 1.0
✅Connector: MCIO 8X to 2 x Mini‑SAS HD SFF‑8643
Key Advantages
1. Space‑saving compact design:
The MCIO connector takes far less internal server space than traditional large‑size SAS connectors, perfect for tight high‑density GPU chassis layouts, helping engineers organize messy internal server wiring.
2. Ultra‑high‑speed reliable throughput:
Rated up to 32GT/s bandwidth, this NVLink breakout cable ensures low‑latency data sync across multi‑GPU training clusters, avoiding bottlenecks during large‑scale AI model computing tasks.
3. Wide protocol compatibility:
Fully compliant with PCIe Gen5 and UPI 1.0 standards. It works seamlessly for GPU‑to‑GPU NVLink interconnection, high‑speed storage backplane links and high‑end workstation internal cabling projects.
4. Durable premium build:
HF oxygen‑free copper core reduces signal loss; 30‑microinch gold‑plated PCB contacts resist oxidation, delivering long‑term stable performance even under 24/7 continuous operation in data‑center environments.
Common Application Scenarios
✅AI GPU training cluster NVLink interconnection
✅High‑density rack‑mount server internal cabling
✅PCIe Gen5 high‑speed storage server breakout wiring
✅HPC high‑performance computing workstation internal connection
