The Quantum-X Photonics switches provide 144 ports of 800Gb/s InfiniBand based on 200Gb/s SerDes and use a liquid-cooled design. Quantum-X Photonics switches offer 2x faster speeds and 5x higher scalability for AI compute fabrics compared with the previous. NVIDIA's co-packaged optics (CPO) switches with integrated silicon photonics are the world's most advanced networking solution for the era of agentic AI. Replacing pluggable transceivers with silicon photonics on the same package as the ASIC, NVIDIA CPO innovations provide 5x better power. Imagine a data center where even the most powerful switches run cool and stable— without noise, thermal throttling, or energy waste. Cisco is actively innovating in direct-to-chip liquid cooling for high-performance switches, laying the groundwork for solutions that will enable seamless and. By replacing traditional pluggable transceivers with co-packaged optical devices (CPO), it enables direct connection between fiber optic cables and switch chips, reducing power consumption in data centers by approximately 40 megawatts while significantly improving network transmission efficiency. NVIDIA unveiled its next-generation silicon photonics switches— Spectrum-X Photonics Ethernet and Quantum-X Photonics InfiniBand —designed to scale AI factories to connect millions of GPUs while cutting energy consumption and improving performance. Compared to undisclosed 'traditional methods,' the company promises 3. 5x more power efficiency, 63x greater signal integrity, 10x better.
