Woofun AI reports that Nvidia has temporarily suspended its adoption of TSMC's COUPE technical solution. The company's initial strategy relied on TSMC's co-packaged optics platform, which utilized 8-wavelength DWDM and approximately 50 to 64G NRZ modulation technology.

The revised approach transitions to Tower Semiconductor's silicon photonics platform. This new configuration implements a 16-wavelength DWDM system alongside a 200G/400G PAM4 modulation solution.
