Transceivers Needed in NVIDIA H100 Server Cluster
Are you familiar with the network architecture of the NVIDIA DGX H100 SuperPOD? Have you had a chance to consider the number of optical transceivers that might be needed? Let’s explore this together, using the NVIDIA 4 SU solution as a guide to estimate the number of optical transceivers.
Network Architecture Information:

800G Optical Transceiver Requirements:

400G Optical Transceiver Requirements:
Each Leaf has 16 downward transmission interfaces, and each interface connects downward to the server at a unidirectional rate of 2*400G.
