Co-packaged photonics 100G vs wireless

Co-packaged photonics (CPO) at 100G offers higher bandwidth, lower latency, and better signal integrity than traditional wireless RF solutions, particularly for high-density, high-throughput network infrastructure.Co-Packaged Photonics (CPO) Overview

CPO integrates optical transceivers directly with switch ASICs or processors, minimizing the electrical path length and reducing signal loss, latency, and electromagnetic interference (EMI) compared to copper-based interconnects . At 100G per channel, CPO enables ultra-high bandwidth density and improved power efficiency by reducing the need for high-power electrical drivers, repeaters, or retimers . This makes it particularly suitable for data centers, AI workloads, and high-performance computing, where traditional electrical interconnects are reaching physical limits .

Wireless Communication Overview

Wireless systems, including 5G and emerging 6G networks, rely on RF components to transmit data over the air. While wireless provides mobility and flexible deployment, RF-based fronthaul and backhaul links face challenges in supporting massive data throughput, ultra-low latency, and dense antenna arrays, especially at millimeter-wave frequencies . Power efficiency and signal propagation are also limiting factors for high-speed wireless links, particularly in infrastructure-heavy deployments .
