The actual number of optical modules used primarily depends on the following factors. Discrepancies in Calculating the Ratio of Optical Modules to GPU-The Varying Usage Quantity Due to Different Networking Architectures. Network Card Model. GPUs such as the A100, H100, and upcoming GH100 require high-speed optical interconnects to link thousands of GPU nodes, enabling large-scale AI model training and inference. Network Card Model It mainly includes two network cards, ConnectX-6. Traditional optical transceivers, especially in 400G and 800G deployments, generate significant heat and demand substantial power just to keep the lights blinking. 1) NIC Models Mainly includes two types of network cards, ConnectX-6 (200Gb / s, mainly used with the A100) mainly used optical modules are MMA1T00-HS (200G Infiniband HDR QSFP56 SR4 PAM4 850nm 100m) and ConnectX-7. Two complementary approaches are used to grow these systems: scale-up (tightly coupling many accelerators as one unit) and scale-out (networking multiple units across racks or clusters). In both cases, optical connectivity is playing an increasingly vital role. Below, we explain the trends in. While the industry-standard OSFP (Octal Small Form-Factor Pluggable) module has successfully enabled 400Gbps, 800Gbps, and 1. 6Tbps optical pluggable modules , it is limited to 32 modules per Rack Unit (RU), typically requiring 2 RUs to achieve 102. 4Tbps and 4 RUs to reach 204. 8Tbps of switching.
