Miniature FORJ,
performance and compactness
Rotary transmission: a key challenge
In the aerospace, defense, energy and industrial sectors, data transmission in rotating systems is a major challenge. In this context, with the volume of information to be exchanged constantly increasing, guaranteeing the integrity of the signal while minimizing interference is becoming essential.
Protecting the signal from external interference and preserving its quality are critical issues. To meet these requirements, contactless transmission is increasingly favored, particularly through the use of FORJs (Fiber Optic Rotary Joints). These devices enable reliable optical data transmission without mechanical wear, ensuring optimum performance over the long term.
Varied applications in demanding environments
Fiber Optic Rotary Joints are widely used in many advanced technology sectors, including:
- Wind turbines
- Underwater Remotely Operated Vehicles (ROVs)
- Satellites and space systems
- Industrial robotics
- Defense systems and military applications
In these often demanding environments, signal integrity must be preserved, even when the space allocated to the Fiber Optic Rotary Joint is extremely limited.
EVERAXIS brings to the table !
Everaxis is responding to these challenges with its miniature FORJ, designed to offer a perfect balance between compactness and performance. The Everaxis miniature FORJ combines the smallest and lightest housing with first-class performance (very low insertion loss and very high return loss). This innovative model combines reduced dimensions with exceptional transmission performance, guaranteeing optimum efficiency even in the most demanding applications.
Key performances :
- Ultra-compact size: an outer diameter of just 6.8 mm, ideal for tight spaces.
- Advanced optical performance: specially developed collimating lenses ensure stable transmission, even at high temperatures and in disturbed environments.
- High data rates: transmission of up to 10G over 40 km and 40G in LAN networks.
- Exceptional durability: designed for long life, limited only by the endurance of the mechanical components.
