Home / The optical module connects to the GPU
The UCIe forms the on-package electrical link between the GPU and the TeraPhys optical chiplet. The actual number of optical modules used primarily depends on the following factors. 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. Several have landed on chiplets using waveguides called microring resonators to encode data lanes onto optical waves from an external laser and filter the appropriate wavelength at the receiver port.
