800G Transceiver Compatibility Guide — Spectrum-4, Quantum-X800, ConnectX-8, BlueField-3
)
NVIDIA's 800G networking lineup spans Ethernet switches (Spectrum-4), InfiniBand switches (Quantum-X800), SuperNICs (ConnectX-8), and DPUs (BlueField-3) — each using different OSFP cage types (IHS vs RHS) and supporting different transceiver protocols. This guide provides the definitive compatibility matrix: which 800G OSFP modules work with which platforms, IHS vs RHS form factor differences, DAC/AOC/ACC breakout options, and recommended cabling for GB200 NVL72 SuperPOD deployments. Includes Vitex's NVIDIA-compatible product portfolio.
