OmniCure AC Large Supports High-Speed Coating Cure in Optical Fiber Draw Towers

Optical fiber manufacturing begins with drawing glass fiber from a preform. Immediately after drawing, the bare fiber is coated with primary and secondary UV-curable coatings to protect the glass and maintain long-term mechanical and optical performance.

In the draw tower, UV curing is a key step that affects line speed and coating reliability. The process must deliver complete and uniform 360° curing at high speed; insufficient cure can lead to delamination and failure, while excessive cure time limits throughput.

Draw speeds are high and the cure window is short. The UV system must cure the coating quickly without becoming the bottleneck.

The coating must be cured uniformly around the fiber circumference. Non-uniform exposure can lead to uneven coating, residual stress, or long-term reliability issues.

Draw towers often run continuously. Frequent maintenance, downtime, or output degradation can directly affect capacity and total cost.

OmniCure AC Large supports high-speed UV LED coating cure in optical fiber draw towers. The platform is suitable for continuous area curing and helps provide uniform exposure around the fiber for primary and secondary coatings.

Compared with traditional curing approaches, UV LED platforms can offer improved energy efficiency, lower maintenance needs, and longer stable operation intervals, making them well suited for 24/7 production environments.

For fiber ribbon coating applications, fiber-optimized systems such as AC922S-F can be evaluated according to the actual production line.

ETIA helps manufacturers evaluate UV curing requirements, select suitable OmniCure systems, coordinate genuine product supply, and provide local technical support for application testing, installation, troubleshooting, maintenance, and long-term service.
