Li-Fi Arthus

Low-Cost Real-Time Link

Li-Fi Arthus enables bi-directional, full-duplex data transmission at 10 or 100 Mbit/s via RJ45 over short distances up to 1 meter. With an alignment tolerance of ~25 cm and optional Plexiglass front plate, it is ideal for close-range industrial applications. The device supports real-time industrial Ethernet protocols such as Profinet and EtherCAT, and offers plug-and-play integration with an Ethernet interface. Designed for safety and flexibility, it is Laser Class 1 certified and housed in a compact 85 × 45 × 65 mm enclosure.

Applications for Arthus

In environments where traditional wireless technologies fall short, our Li-Fi (Light Fidelity) solutions deliver secure, interference-free, and ultra-fast data communication using light. Our systems enable seamless connectivity in even the most challenging conditions.

Warehouse logistics

High-reliability, interference-free communication during docking or loading processes. Its full-duplex, plug-and-play design allows fast data exchange with stationary units such as charging stations or control terminals over short distances, enabling real-time updates, task uploads, or diagnostics without physical connectors.

Industry automation

Reliable data exchange between moving machinery and stationary control units over short distances - ideal for tool changers, rotary tables, or production line modules. Its bi-directional, full-duplex communication supports real-time industrial Ethernet protocols, ensuring low-latency, high-precision operation.
