Overview
The DustPhotonics 1.6T silicon photonics engine is the first merchant SiPh engine purpose-built for 1.6T DR8 applications, targeting AI and hyperscale data center interconnects. It packs eight independent 224G channels for 1.6 Tbps aggregate throughput, with a four-channel variant covering 800G DR4.
Both versions integrate on-board lasers using DustPhotonics' proprietary L3C (Low-Loss Laser Coupling) technology, which reduces optical loss and simplifies transceiver design. A lower-cost single-laser option covers short-reach links up to 100 m, while the full engine reaches up to 2 km.
The platform supports LRO (Linear Receive Optics) and LPO (Linear Pluggable Optics) applications and is qualified for immersion-cooled data centers an increasingly common deployment for high-density AI racks. DustPhotonics also ships the Tamar200 1.6T-2xFR4 PIC (200G per lane) and Carmel 400G/800G PICs from the same SiPh portfolio.
Key Benefits
First-to-market merchant 1.6T DR8 SiPh engine de-risks next-generation transceiver designs; L3C laser coupling lowers optical loss and bill-of-materials; integrated on-board lasers and athermal multiplexers remove external-optics complexity; native LPO/LRO support cuts module power for AI scale-out fabrics.
Applications
1.6T DR8 / 800G DR4 pluggable transceivers, co-packaged optics (CPO), AI and hyperscale data center interconnects, immersion-cooled AI racks, and merchant SiPh supply for transceiver OEMs.
