Revolutionary Optical I/O Technology

At the heart of Ayar Labs' innovation is its ability to shrink fiber optic data transmission technology to the chip scale. The company's flagship product, the TeraPHY optical I/O chiplet, delivers an impressive four terabits per second of bi-directional bandwidth with ultra-low latency, while consuming only 10 watts of power 1

. This breakthrough in energy efficiency could be a game-changer for modern AI workloads, which demand enormous data throughput.

Complementing the TeraPHY chiplet is the SuperNova Light Source, which supplies 16 wavelengths of light to power 16 ports and 256 data channels. This solution offers significant improvements over traditional electrical interconnects:

• 5-10x higher bandwidth
• 10x lower latency
• Up to 8x greater power efficiency 1
