Fiber Optic Measurement
and Quality Control Solutions
Fiber production requires highly accurate measurement systems capable of monitoring critical process parameters at increasingly high drawing speeds. CERSA MCI develops advanced fiber optic measurement solutions that help manufacturers ensure product quality, optimize production processes and achieve reliable inline quality control.
For many years, CERSA MCI has worked closely with optical fiber manufacturers to develop measurement technologies tailored to the needs of modern fiber production lines. Today, more than 650 high-speed fiber drawing towers worldwide operate with CERSA MCI measurement systems.
Why Fiber Optic Measurement Matters
Modern fiber production requires continuous monitoring of critical process parameters to ensure product quality and maximize production efficiency. Real-time measurement systems help manufacturers control fiber diameter, tension, airline defects and coating quality while operating at increasingly high drawing speeds.
Key Parameters Monitored During Fiber Production
• Bare fiber diameter measurement
• Airline defect detection
• Fiber tension monitoring
• Coating quality inspection
• Asymmetry and concentricity control
• Real-time process optimization
Full Inline Quality Control
By installing measurement instruments throughout the draw tower, operators can continuously monitor and adjust key production parameters. These systems provide immediate feedback for process optimization and quality assurance. For bare fibers, important measurements include cladding diameter, airline defects, tension and spinning profile. After coating application, additional measurement systems help monitor final diameter, geometry defects such as lump and neckdown, and coating defects including bubbles, delamination and impurities.

Monitoring Fiber Quality
Fiber quality depends on the continuous monitoring of multiple process parameters throughout the entire drawing process.
By installing dedicated measurement systems at strategic positions along the draw tower, manufacturers obtain immediate feedback that allows rapid process adjustments and stable production conditions.
During bare fiber production, CERSA MCI solutions monitor critical parameters such as cladding diameter, airline defects, drawing tension and spinning profile.
After coating application, additional systems verify the final coated diameter, detect lump and neckdown defects, identify coating imperfections including bubbles, delamination and impurities, and monitor coating asymmetry and concentricity. Together, these measurements provide comprehensive inline quality control while supporting increasingly high production speeds.
