Does the B200 require an optical module

The NVIDIA B200 GPU itself does not include an optical module, but systems using B200 or GB200 GPUs employ OSFP optical modules for NVLink interconnects.

The B200 GP

U is a professional graphics card designed for AI and high-performance computing workloads. It features dual Blackwell GPUs, tensor cores, and HBM3e memory, but it does not have display outputs or built-in optical modules for direct connectivity to monitors or networks. It connects to the system via PCI-Express 5.

0 x16 and is intended for integration into AI servers like the NVIDIA DGX B200. For high-speed interconnects, NVIDIA systems using B200 or GB200 GPUs utilize OSFP optical modules in NVLink switches.

Each OSF

P module can support 16 pairs of differential signal lines, enabling 4 NVLink ports per module.

NV

Link switches in these systems can include multiple OSFP modules, providing cumulative support for dozens of NVLink4 ports, which allows GPUs to communicate at extremely high bandwidths across compute trays and switch trays. This optical module infrastructure is part of the system-level design rather than the GPU card itself. In summary, while the B200 GPU does not have an optical module, the DGX B200 system and NVLink switches that integrate B200 GPUs rely on OSFP optical modules to achieve high-speed inter-GPU connectivity for AI workloads.
