Selection and Application of Low-Loss Materials for High-Speed Optical Module PCBs
As AI large language models (LLMs), high-performance computing (HPC), cloud computing, and data center networks continue to evolve, 400G, 800G, and even 1.6T optical modules are becoming increasingly widespread. Higher data rates require higher-frequency signal transmission, placing greater demands on PCB signal integrity, impedance control, and signal loss performance. As the primary carrier for high-speed electrical signal transmission inside optical modules, PCBs must not only achieve precise impedance control but also use low-loss materials to reduce transmission loss and maintain signal integrity. As a result, low-loss materials have become an essential part of high-speed optical module PCB manufacturing. As a professional optical module PCB manufacturer, HoYoGo specializes in the manufacture of high-reliability, high-speed PCBs. We provide customized multilayer optical module PCB manufacturing services to meet diverse customer requirements, deli...
