Control System for Optical Cable Sheathing Production Line

Modern optical cable sheathing production lines use PLC-based control systems with AI optimization, precision extrusion, and real-time monitoring to ensure high-quality, consistent cable production. Overview of the Production LineAn optical cable sheathing production line is an industrial system that applies polymer sheaths onto optical fiber cores using extrusion processes. The line typically includes components for loose tube or tight buffer sheathing, temperature-controlled extruders, laser measurement systems for micron-level accuracy, and host monitoring systems for real-time supervision.

These systems are designed to produce cables for telecommunications, data centers, and outdoor network deployments.

Control System Design

Modern control systems integrate Programmable Logic Controllers (PLCs) as the central control unit to coordinate all subsystems, including extruders, cooling units, and take-up mechanisms. Industrial computers often replace traditional touch screens as the host interface, providing enhanced monitoring, data logging, and management capabilities. The control system architecture typically includes: Digital control of extrusion parameters such as temperature, pressure, and screw speed to maintain consistent sheath thickness (±0.

02 mm accuracy in high-precision systems),. Laser-based diameter measurement for real-time feedback and automatic adjustment of extrusion parameters. AI-based optimization algorithms, such as ant colony optimization, to improve PID control performance and fine-tune process parameters for maximum efficiency and quality.

Host monitoring software for centralized supervision, alarm management, and production data analysis.
