Nvidia's Spectrum-X and Broadcom's Bailly CPO switches are now in mass production, delivering significant performance improvements. The Spectrum-X offers up to 400 Tb/s switching capacity, while the Bailly reduces power consumption by 70% compared to traditional optical transceivers.
Despite this progress, supply chain bottlenecks threaten scalability, particularly regarding the optical engine, silicon photonics precision, and advanced packaging. Foundries like TSMC and GlobalFoundries are ramping up support for silicon photonics technology, crucial for future data center efficiency. Vertical integration may become essential for companies aiming to dominate the CPO switch market by 2027-2028.
