Semtech introduced 200G per channel PMD (Physical Medium Dependent) ICs for 1.6T modules and developing 400G per channel solutions for upcoming 3.2T connectivity. These advancements respond to the growing demand for higher speed, lower latency, and improved power efficiency driven by AI, ML, and LLM workloads.
The new 200G FiberEdge™ components include 112GBd PAM4 transimpedance amplifiers (TIAs) and laser drivers, offering a path to energy-efficient 800G and 1.6T optical modules. Designed to meet stringent power and footprint requirements in hyperscale environments, these components support various pitch formats and mounting techniques. Semtech is also preparing 400G per channel solutions aimed at 3.2T module designs, with early samples now in customer hands.
Semtech’s portfolio reflects a broader strategy to enable scalable data center fabrics for AI infrastructure, where exponential model growth demands high-throughput, power-aware connectivity. The company is positioning its 200G and 400G per channel architectures as foundational to future deployments across hyperscale and enterprise AI environments.
