Fiber Coloring Machine Overview
Fiber coloring machines apply durable color codes to optical/industrial fibers. Precision applicators, fast curing, tension control, and smart sensors are used. This process ensures efficient production. It is designed to easily integrate with existing drawing and coating lines. Additionally, it connects to inline testing and automation systems for efficient operations.
The applicator or marking head applies UV inks or liquid dyes accurately. LED or focused UV cures inks immediately. Fibers keep moving at speed without delay. Transport guidance and tension control systems maintain the fiber’s shape while it is being marked. Pumps/filters feed from reservoirs/tanks consistently. A PLC and HMI ease control, allowing for quick changes and adjustments. Sensors verify placement so every mark meets spec.
How they work together
The applicator synchronizes deposits according to fiber movement, controlled by sensors. The curing process instantly sets the ink, preparing it for further handling.

Fiber Ribbon Lines: High-Speed Methods
Modern ribbon lines combine coated fibers into a flat ribbon. Geometry and attenuation are tightly controlled. Manufacturers use precise alignment, controlled glue application, and rapid curing. This ensures production flowing without compromising quality. Ribbon formation, FRP 05 style lines, and inline proof testing are pivotal in high-throughput settings.
Ribbon creation begins with exact spacing and placement. Machines dispense a slim polymer bead to bond fibers, while tensioning systems counteract micro-bends. Quick-drying stations solidify the adhesive, allowing ribbons to move at line speed. Controlled glue keeps optical quality and eases downstream steps.
FRP 05 lines excel in scale. Up to 24 fibers at ~1,000 m/min is achievable. These systems combine refined tension control, high-accuracy ferrules, and coordinated capstans. This ensures consistent fiber pitch and alignment throughout the process. Thus, FRP 05 is a dependable choice for CO/FTTH ribbon supply.
Inline proof testing confirms ribbon quality. It uses test heads that assess tensile strength and continuity right after the ribbon is made. Should they detect any weakness or breakage, the system either discards the flawed segment or adjusts automatically. This immediate feedback reduces waste and blocks faulty ribbons from progressing to cable assembly.
Ribbon lines may add marking/color coding. This way, identifiers remain intact through subsequent processing. Pairing color coding with inline proof tests enhances traceability and streamlines quality control. Syncing glue/formation/testing yields clear benefits for throughput.
