PROMOTIONAL FEATURE
Transforming Free-Space Data Transmission in Rotary Joints The New Hamamatsu Optical Transceiver: As Industry 4.0 evolves, the demand for fast, efficient, and reliable data transmission is more important than ever. With the growing number of sensors and actuators in robotics, ensuring smooth data exchange is a necessity.
THE EVOLUTION TO FREE-SPACE OPTICAL DATA TRANSMISSION Building on the foundation of FORJ technology, free-space optical data transmission represents a significant evolution. Unlike FORJ, which relies on optical fibers, free-space optical transmission eliminates the need for these fragile components. This advancement allows for even greater reliability and durability, as there are no fibers to break or degrade over time. accelerated wear, especially when rotary speeds exceed 1000 rpm. At these high speeds, slip rings often fail, making optical data communication the only viable alternative. The Fiber Optic Rotary Joint Industries rely on real-time data exchange, yet transmitting information through rotating joints presents considerable challenges for engineers. Traditionally, slip rings have been employed to address this issue. They are subject to limitations, though, such as frequent maintenance requirements, susceptibility to electromagnetic interference, and
