A source said Nvidia has decided to temporarily stop using TSMC’s COUPE technology solution. According to Odaily, Nvidia’s earlier “Plan A” was based on TSMC’s COUPE co-packaged optics platform, using 8-wavelength DWDM and about 50G to 64G NRZ modulation technology.
The source said Nvidia’s latest “Plan B” shifts to Tower Semiconductor’s silicon photonics platform, using 16-wavelength DWDM and 200G/400G PAM4 modulation.
