Israeli New Fiber Optic Sensor Company

Prisma Photonics is an Israeli startup developing AI-driven fiber-optic sensing technology for real-time monitoring of critical infrastructure.

Prisma Photonics, founded in 2017 by electrical engineer Dr. Eran Inbar, specializes in fiber-optic sensing systems that monitor large-scale infrastructure such as power grids, pipelines, secured compounds, and military perimeters . The company's technology converts existing optical fibers into intelligent sensor networks, enabling real-time detection and classification of threats like wildfires, ice, wind, physical damage, and grid congestion without installing additional sensors .

Technology and Applications

Prisma's Hyper-Scan AI platform leverages machine learning and advanced algorithms to process optical fiber signals, providing meter-level accuracy in detecting events across hundreds of kilometers . The system supports:

• Power transmission optimization: Boosting throughput by 20–30% without physical upgrades .
• Renewable energy integration: Dynamically monitoring line conditions to accommodate wind and solar power .
• Security and defense: Protecting military installations and long remote boundaries .
• Infrastructure resilience: Early detection of extreme weather or physical damage to prevent outages . The technology is already deployed by 15 Tier-1 transmission operators in the U.S. and Europe, and Prisma is expanding into Latin America and Germany, including a partnership with TransnetBW to monitor 120 km of high-voltage lines .

Funding and Growth

Prisma Photonics has raised $80 million in total funding, with the latest $30 million round led by Israeli defense-tech fund Protego Ventures, alongside Spain's Adara Ventures and Latin American utility investors . Previous rounds included participation from Insight Partners, Elements, SE Ventures, and Israel Electric Corporation . The funding supports global expansion, AI platform development, and deployment across critical infrastructure networks.

Strategic Impact

By transforming existing fiber networks into continuous smart sensing systems, Prisma Photonics enables utilities and governments to enhance grid reliability, optimize energy flow, and improve security without costly infrastructure upgrades . Its AI-driven approach allows simultaneous monitoring for energy efficiency, environmental threats, and security risks, making it a versatile solution for modern infrastructure challenges .
