Engineering the Nervous System of 2026 AI Factories
224G PAM4 Signal Integrity: Our 224G internal cables utilize advanced shielding and ultra-low-skew twinax to support 224Gb/s per lane, perfect for the next generation of AI accelerators.
Bend-Insensitive G.657.A2 Fiber: Specifically for congested AI racks, our internal fiber cables can handle a 7.5mm bending radius without signal loss, allowing for much higher cabling density.
Vietnam Hub for Global Compliance: Our Vietnam facility enables US hyperscalers to achieve a Non-China Sourcing Strategy, ensuring Duty-Free import of mission-critical PCIe 6.0 and 7.0 components.
Linear Active Copper (ACC) Innovation: We solve copper’s distance limits with Internal ACC that boosts signals with low power consumption, ideal for switch-to-GPU links up to 3 meters.
Liquid-Cooling & Immersion Readiness: As GPU racks surpass 100kW, our cables feature fluoropolymer jackets that remain chemically stable in direct-to-chip or immersion cooling environments.
1.6T GPU AI Clusters: Internal high-speed links for ultra-scale GPU-to-GPU fabric (NVLink/Infinity Fabric equivalent) within high-density racks.
CXL Memory Pooling: CXL 4.0 compliant cables for cache-coherent memory expansion, enabling disaggregated memory across AI server nodes.
Near-ASIC Flyover Connectivity: Internal flyover assemblies that route signals directly from the processor to the IO, bypassing lossy PCB traces for 112G/224G paths.
Sustainable Data Centers: LSZH jacketed cables for hyperscalers focused on ESG goals and non-toxic, recyclable infrastructure.
Sub-inch Accuracy GPS/ADAS Systems: Shielded internal high-speed links for the "Edge AI" compute nodes within autonomous vehicles.
