Core Viewpoint - The company has successfully developed and delivered 224G high-speed communication cables using two mainstream technical solutions: physical foaming technology and solid material technology, which have passed rigorous certification from leading global clients [1] Group 1: Technology Overview - The mainstream technical solutions for 224G high-speed communication cables are physical foaming technology and solid material technology [1] - Physical foaming involves mixing inert gases like nitrogen under pressure to create uniform, sealed micro-pores, requiring precise equipment and high operational skills [1] - The solid core structure is created using a specially designed extruder mold to form longitudinal through-holes, which can allow moisture to enter and affect dielectric constant stability, leading to signal attenuation [1] Group 2: Product Stability - Physical foaming provides better stability as the inert gas in sealed bubbles is less likely to flow, resulting in minimal deformation during bending and less moisture intrusion [1] - In contrast, the solid core structure can experience significant changes in dielectric constant due to air movement within the holes during bending, affecting transmission speed stability [1] Group 3: Future Developments - The company is currently conducting preliminary research on the next generation of 448G high-speed communication cables [1]
