high-speed production
The OFC 40 delivers production speeds of up to 1250 m/min, allowing manufacturers to significantly increase throughput while maintaining stable and controlled process conditions. This ensures consistent product quality even at high output levels, supporting both productivity goals and reliability requirements.
dual clenching technology
Dual clenching for enhanced product stability
The dual clenching technology in the OFC 40 ensures superior dimensional stability of the loose tube. By effectively eliminating post-shrinkage effects, it helps maintain consistent tube geometry after production. Reducing variability and improving overall cable performance.
Flexibility for evolving cable designs
To support a wide range of applications, the OFC 40 is designed to handle both jelly-filled and dry tube production. This flexibility allows manufacturers to respond quickly to changing market demands and customer specifications without compromising efficiency.
The line accommodates 1 to 24 fibers, making it suitable for diverse cable constructions and enabling seamless adaptation across product portfolios.
low scrap & optimized material usage
Optimized fiber launching, cutting, and stable process conditions minimize material loss. This results in higher yield, lower costs, and more efficient production.
precise EFL control
Accurate fiber excess length (EFL) control is critical for cable performance, especially at high speeds. OFC 40 ensures stable and precise EFL for consistent mechanical and optical performance.
advanced process control
Combines real-time monitoring and automated adjustments to maintain stable production conditions. Minimizes process deviations and ensures reliable performance at high speeds.
