Overview
NADDOD's 1.6T portfolio centers on the OSFP-1.6T-2xDR4/DR8, a cost-effective dual-port OSFP transceiver delivering 2 x 800Gb/s with 8 x 212Gb/s PAM4 modulation across electrical and optical interfaces. It pairs with two MPO-12/APC patch cables for links up to 500 m.
The module is purpose-built for 1.6T InfiniBand XDR fabrics: it interconnects NVIDIA Quantum-X800 Q3400 switches which need 72 x 1.6T OSFP224 modules per switch to reach full 144-port 800Gb/s capacity and also connects to NVIDIA ConnectX-8 SuperNICs using 800G XDR transceivers.
The 1.6T module carries an industry-first 200G PAM4 3nm DSP, while the 800G OSFP DR8/2xDR4 line uses Broadcom DSP for signal equalization. RHS (riding-heatsink) and flat-top variants target 102.4T Broadcom Tomahawk 6 liquid-cooled switches, and the wider portfolio spans 1.6T down to 100G with DAC/AOC/ACC cabling.
Key Benefits
Validated for NVIDIA XDR fabrics (Quantum-X800 Q3400 and ConnectX-8); industry-first 200G PAM4 3nm DSP; RHS/flat-top form factors for liquid-cooled switches; single-platform sourcing across 1.6T, 800G and 400G optics and cabling.
Applications
1.6T InfiniBand XDR AI fabrics, 800G Ethernet/NDR deployments, NVIDIA Quantum-X800 and ConnectX-8 networks, RoCE scale-out, and liquid-cooled 102.4T switch racks.
