How to solve the heat dissipation of 400G high-speed optical modules

Optical module manufacturers now list 400G optical modules as key research and development objects. While providing powerful functions, optical modules have their own power consumption and related heat generation increased sharply. Coupled with the compactness of the space, the requirement of multiple plug-in and unplugging, and the controllable temperature management, it brings challenges to the heat dissipation of the optical module.
