According to LightCounting, sales of lasers and photonic integrated circuits for optical transceivers are expected to grow from $2. 9B by 2029, fueled largely by AI data centers. Read on to learn key CPO trends shaping AI systems in 2026 and the challenges designers will need to. At the core of this infrastructure lie optical modules—ingenious devices that convert electrical signals into optical signals, enabling lightning-fast data communication over fiber optic cables. As bandwidth scales from 400G to 800G and beyond, traditional pluggable optics architectures are reaching their physical limits. These links connect CPUs, GPUs, AI accelerators, and memory in compute fabrics where latency and bandwidth density dominate every other metric. Once again, the way data travels has become central to how fast information can be shared. This bottleneck is especially true in scale-up GPU fabrics. The optical communication industry is entering a new phase of accelerated growth, driven by the rapid expansion of AI infrastructure.
