Light brought onto the switch package — the next power saver.
您正在查看一条技术记录：AI 硬件的一个基础构件——它的功能、谁来制造，以及哪些芯片和系统使用它。
CPO integrates the optical engines beside the switch ASIC itself, cutting the electrical distance and roughly 3x-ing interconnect power efficiency (vendor figures). NVIDIA's Quantum-X and Spectrum-X Photonics switches (announced 2025) and Broadcom's Bailly lead the transition; TSMC's COUPE process underpins several designs.
