Li-Fi Pharlan®

Directional High Performance Data Link

Li-Fi Pharlan® is a powerful optical communication system designed for high-performance, long-range industrial connectivity. It delivers full-duplex, bi-directional data transmission at 1 Gbps (1.25 Gbd) and beyond, with an additional 1 Mbps side channel, over distances up to 200–300 meters depending on lens configuration. With ultra-low, deterministic latency well below 1 µs and no interference from RF environments, Pharlan® is ideal for time-critical, mission-sensitive applications. It supports TSN and is compatible with industrial Ethernet protocols such as Profinet, EtherCAT, EtherCat-G and SERCOS III. Featuring plug-and-play functionality, Gigabit Ethernet interface, and patented technologies including a multipath lens system, Li-Fi Pharlan® ensures robust, eye-safe (Laser Class 1) communication in a rugged 119 × 62 × 97 mm housing.

Applications for Pharlan®

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.

Logistics

Fast, interference-free communication between moving systems (cranes, automated storage units, conveyor systems). Up to 300 m range, ultra-low latency, and compatibility with industrial Ethernet protocols enable real-time control and coordination without the wear, complexity, or signal issues of cables and RF systems.

Industrial communication

Reliable, high-speed communication for automated and semi-automated production lines. With up to 300 m range, full-duplex 1 Gbps data rates, and ultra-low latency below 1 µs, Li-Fi Pharlan enables real-time data exchange between sensors, controllers, and machinery.

Constructions

Robust, wireless communication links for freefield crane operations and backup systems. Offering up to 300 m range, full-duplex 1 Gbps speeds, and ultra-low latency, Li-Fi Pharlan ensures reliable, interference-free data transfer between cranes and control centers. 

Infrastructure

Secure, high-speed communication for railway safety systems and backup links. With up to 300 m range, ultra-low latency, and full-duplex 1 Gbps data rates, Li-Fi Pharlan supports real-time monitoring and control in critical rail operations as well as infrastructure-2-infrastructure.
