PHYSICAL AI · REAL-WORLD DATA

Sensing the physical world.
Real data for physical AI.

Optical fiber: a data carrier, a sensing element and a foundation for world models.

In the era of physical AI, optical fiber is an important medium for both sensing and data transmission. Passive, continuous, spatially resolved sensing with immunity to electromagnetic interference turns the real condition of critical assets into usable data for asset management, digital twins and world models.

With no individual power supply needed along the sensing fiber, long-life, low-maintenance deployments reduce field power and maintenance requirements.
