Overcoming Crosstalk in 224G DACs: The Precision Alignment of High-speed Taping Machines
I. Introduction: The 224G Paradigm Shift The global appetite for data is insatiable. As we transition from 400G and 800G towards 1.6T networking architectures, the physical layer is under unprecedented pressure. At the heart of this evolution is the 224G per lane (PAM4) standard, which represents the current frontier for Direct Attach Cables (DACs). While fiber optics are essential for long-haul transmission, high-speed copper DACs remain the most cost-effective, energy-efficient solution for short-reach intra-rack connections in AI-driven data centers. However,
