With the continuous improvement of device communication speed, traditional PCB interconnects have encountered huge challenges in signal attenuation indicators, especially for large-sized interconnect architectures above 56G. The loss advantage of Cable has shown engineers new directions for breakthroughs. The loss of Cable is only 25% of the same length of PCB wiring; The introduction of local cable schemes can promote the degradation of PCB boards and provide opportunities for cost reduction; The low loss advantage of the Cable scheme allows signals to be transmitted further, thereby reducing the use of CDR and effectively reducing power consumption;
