Advanced Testing Laboratory
To guarantee zero signal dropouts in your GPU computing arrays, our in-house lab is equipped with industry-leading SI testing instruments:
• Equipment: 67 GHz Vector Network Analyzers (VNA) & TDR.
• Impedance Control: 85Ω ± 10% strictly monitored across the entire cable length.
• Reporting: Digital test reports, touchstone (.s4p) files, and eye diagram analytics available for every production batch.
Frequently Asked Questions
Yes. Unlike standard off-the-shelf cables, we specialize in custom pinout mapping. whether you need MCIO 8i to 2x 4i breakouts, crossed wiring, or specific sideband definitions to match your proprietary motherboard or riser card design, we can configure it accurately based on your pin-map definition.
Absolutely. For PCIe 5.0 (32 GT/s) applications, signal integrity is critical. We provide 100% VNA (Vector Network Analyzer) testing for every batch. Detailed test reports, including Insertion Loss, Return Loss, and Eye Diagram analysis, can be provided with your shipment upon request.
To maintain optimal signal margin without retimers, we recommend keeping passive copper cable lengths under 500mm (0.5m) for PCIe Gen 5. However, using our ultra-low-loss silver-plated twinax (30AWG), we can achieve longer distances. Contact our engineering team for a specific loss budget calculation.
We are built for speed.
Prototypes: 5-7 days (using in-stock raw materials).
Mass Production: 2-3 weeks typical lead time.
We offer expedited services for urgent NPI (New Product Introduction) builds to help you meet your launch deadline.
We operate with a highly flexible Low MOQ policy tailored to High-Mix, Low-Volume (HMLV) manufacturing. While exact minimums depend on raw material availability and custom tooling requirements, we actively support small-batch pilot runs for your R&D, EVT, and DVT stages. Our goal is to validate your design efficiently and scale seamlessly into volume production.
Yes. Our MCIO connectors comply with SFF-TA-1016 standards. They are fully cross-compatible with receptacles from major brands like Amphenol, Molex, and TE Connectivity, ensuring a perfect fit for your existing hardware infrastructure.
