Modern AI and accelerated-compute networks rarely transition between speed generations all at once. In production environments, 800G and 1.6T links must coexist reliably within the same fabric. To remove uncertainty for system engineers and infrastructure teams, Axiom engineers validated OEM-alternative 1.6T and 800G OSFP optics on NVIDIA platforms in Axiom U.S. labs.
• 1.6T OSFP 2×DR4 optics
• 800G OSFP DR4 optics
• NVIDIA Q3200 switching platform
• NVIDIA CX-8 networking
• Lenovo server environment (CX-8 NIC integration)
• Mixed-speed operation (1.6T and 800G concurrently)
• Successful link training across 1.6T ↔ 800G connections
• 800G OSFP DR4 optics
• Correct DR4 lane mapping and breakout behavior
• Forward Error Correction (FEC) within expected thresholds
• Clean diagnostics and telemetry reporting
• Zero bit errors observed during sustained traffic testing
This validation enables phased upgrades from 800G to 1.6T, shorter qualification cycles, reduced deployment risk in AI and HPC environments, and greater sourcing flexibility without sacrificing reliability.
