System Description

Like fibre-optic cable. But wireless.

What is KORUZA?

KORUZA v2 Pro is a wireless free-space optical (FSO) communication system that serves as an alternative to laying fibre-optic cable. It is a low-maintenance, interference-free operation, designed for industrial and urban areas and can be rolled-out with minimal infrastructure investment.

Data is securely transmitted over a collimated laser beam at 1 Gbps or 10 Gbps transfer speed at distances up to 150 m. KORUZA v2 Pro is using an eye-safe IR laser beam.

Examples of Use-Cases

  • Optical communication systems in urban areas (replacing expensive installation of fibre optic cable, campus connectivity)

  • Industrial sites (cable-less cranes, manufacturing facilities)

  • Public infrastructure (railway applications, high data throughput applications)
