The design and manufacturing of PCB boards play a crucial role in determining the performance indicators of the six types of modules, with important parameters including insertion loss, return loss, and near-end crosstalk. Failure mechanisms such as signal leakage from modules and plugs can be addressed through approaches like balanced transmission and high-speed communication connector manufacturing. Domestic counterparts need to focus on designing compensation circuits and optimizing process parameters for successful trial production of super six-type modules.
