Melvin(@MelvinInvests):AI’s biggest bottleneck is moving data and that could still create huge opportunities for optical networking companies (Save this) The chart shows a 1.6T optical transceiver, a device that transfers data between AI servers, switches, GPUs, and fiber optic networks. 1.6T means it can theoretically move up to 1.6 terabits of data per second, or 1,600 gigabits and that is about twice the speed of an 800G connection. This technology is important because AI data centers contain thousands of GPUs that must constantly exchange information. As AI models become larger, slow connections can leave expensive processors waiting for data but faster optical links help reduce that bottleneck and allow AI clusters to operate more efficiently. This image shows two directions of travel. The TX path converts electrical data from a server or switch into light which travels through fiber. The RX path receives that light and converts it back into an electrical signal for another device. And inside the module are several key components. Optical DSPs process and correct the signal, laser drivers control the lasers, modulators place data onto the light, and photodiodes convert incoming light back into electricity. Amplifiers, timing chips, thermal sensors, power management devices, and high speed connectors help the system operate reliably. Optical fiber becomes more attractive at higher speeds because copper connections lose efficiency over longer distances. At 1.6T, copper may only be practical across very short distances while optical technology can move data farther with better bandwidth and lower signal loss. This creates an investment opportunity beyond the companies making AI chips. NVIDIA remains a major beneficiary because its AI systems require fast connections between GPUs. Broadcom and Marvell could benefit from their networking chips, custom silicon, and optical connectivity products. Coherent and Lumentum are important optical suppliers with exposure to lasers, photonics, and high speed transceivers while Applied Optoelectronics is a more direct transceiver play and has announced a volume order for 1.6T data center products. Arista Networks and Cisco could benefit by selling the switches and networking systems that connect AI servers. Chinese suppliers such as Innolight, Eoptolink and Accelink Technology could also benefit as China expands its AI data center infrastructure.
