Overview
Source Photonics offers a complete 1.6T and 800G PAM4 optical transceiver family for hyperscale and AI data centers. The 1.6T series spans DR8, 2xFR4, 2xLR4, LRO and AEC copper modules, while the 800G series covers DR4, FR4 and LR4 based on single-lambda 200G PAM4 in OSFP or QSFP-DD form factors.
Source Photonics began production shipments of 200G single-lambda PAM4 800G/1.6T transceivers as 1.6T adoption took off from 2025, with both EML CoC and silicon-photonics PIC variants available. The company has demonstrated live 1.6T links interoperating with 102.4 Tbps switch platforms and is developing 12.8T XPO, 6.4T ELSFP and 400G-per-lambda TOSA components for the 3.2T generation.
Key Benefits
Full portfolio: 800G through 1.6T with pluggable, LRO, LPO and AEC options. Proven at scale: 1.6T DR8 in production volume. Roadmap: 12.8T XPO and 400G/lambda components for 3.2T.
Applications
AI and ML cluster fabrics, hyperscale/cloud data center scale-out, 1.6T-to-102.4T switch interconnect, linear (LPO/LRO) low-power links.
