Markets and Standards
The spike in transceiver demand for AI cluster and data center application is a consequence of the increased data traffic coming from the introduction of large language models (LLM) that power the life of ever more humans every day. Not only the numbers of transceivers sold is sharply increasing, but also their specs, essentially doubling every three years. With 3.2T transceiver sampling in 2027 and volume in 2028, Polariton offers enabling products and technology today.
- InfiniBand GDR (2027): example 3200G implemented with 8x 400G per lane channels, 212.5 GBd PAM4
- InfiniBand LDR (2030): example 6400G implemented with 4x 800G per lane channels, 425 GBd PAM4
- Ethernet 3.2TbE (2027): implemented with 8x 400G per lane, 224 GBd PAM4
- Ethernet 6.4TbE (2030): implemented with 8x 800G per lane, 448 GBd PAM4
Reducing the number of lanes in transceivers improves yield, enhances end product reliability, and lowers system power consumption.
Pluggable IM/DD Transceivers
While the industry is evaluating various electro-optic platforms, Polaritons enables customers today. Plasmonic ring resonators fulfill the optical power budget and provide the ER/OMA/BER performance required for IM/DD.
