Third Generation Optical Module
This article unpacks the technologies powering this leap (silicon photonics, advanced modulation, and co-packaged optics), compares deployment paradigms, and delivers a tactical upgrade roadmap that balances performance, cost, and scalability. (NASDAQ: AVGO) today announced significant advancements in its co-packaged optics (CPO) technology with the launch of its third-generation 200G per lane (200G/lane) CPO product line. Lasers: DFB (Distributed Feedback) lasers or VCSEL (Vertical Cavity Surface Emitting Lasers) for short reach Modulators: Silicon photonic Mach-Zehnder modulators or electro-absorption modulators Photodetectors: Germanium-on-silicon PIN or APD photodetectors DSP: 7nm or 5nm CMOS process nodes. Pluggable optical transceiver modules are essential components in data communication systems, widely used as optical interconnects at the termination of fiber optic links. As AI model training and inference scale to thousands of GPUs, traditional network architectures are being pushed to their limits. This article provides a strategic and technology-focused roadmap for the evolution of optical modules from 400G to 800G, 1.
