Performance Comparison of Energy-Saving Optical Protection Switches and Copper Cables
In this paper, we introduce MOSAIC, a novel optical link technology that breaks the optics versus copper trade-off, enabling long reach, low power, and high reliability simulta-neously. Copper cable solutions, traditionally used for short-distance intra-rack interconnects, are increasingly facing challenges in both transmission density and energy efficiency. By comparison, Micro LED co-packaged optics (CPOs) offer significantly lower energy consumption per bit of data. When setting up an industrial network, one of the most critical decisions is choosing between fiber optic switches and copper switches. on a narrow-and-fast architecture with a few high-speed channels, MOSAIC adopts a wide-and-slow design, employing hundreds of par-allel.

Is there a relationship between optical modules and CPOs
CPO optical modules put optical and electronic parts together. They make the signal path much shorter, from centimeters to millimeters. This can cut power use by up to half. CPO technology lets more data fit in. In high-speed optical communication, optical modules are traditionally packaged as separate devices where optical chips (lasers, modulators, photodetectors) and electronic chips (drivers, TIAs, DSPs) are integrated into a module housing. This helps data move faster and saves. From Jensen Huang showcasing CPO switches at GTC 2025 to a wide range of vendors demonstrating optical engines integrated inside ASIC packages at OFC 2025, co-packaged optics are everywhere. However, it's worth noting that Andy Bechtolsheim, co-founder of Arista and a long-standing visionary in.
