When connecting an 800G NVIDIA InfiniBand OSFP twin-port transceiver to four 400G OSFP/QSFP112 transceivers
offering a cost-effective alternative to optical solutions due to their simple architecture and minimal component count
HPC and storage area network
powered by the Quantum-3 ASIC，leverages 200Gb/s-per-lane serializer/deserializer (SerDes) technology
The two cards should be installed into two PCIe x16 slots and connected using an MCIO cable
Generic Compatible Broadcom DSP & Broadcom VCSEL 400GBASE-VR4 QSFP-DD PAM4 850nm 50m MTP/MPO-12 MMF Optical Transceiver Module Ethernet Transceivers When connecting an 800G NVIDIADescription NADDOD 400G QSFP DD VR4 optical transceiver is a multimode, 4 channel (VR4) optical module designed for 400 Gigabit Ethernet (GbE) links over up to 50 m of OM4 multimode fiber. The QDD 400G VR4 converts eight lanes of 50 Gb s PAM4 electrical signals into four lanes of 100 Gb s PAM4 optical signals at a nominal wavelength of 850 nm, enabling a total aggregate data rate of 400 Gb s. The 400G QSFP DD VR4 optical transceiver delivers ultra
