High-speed fiber ribbon line and ribbon production 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. Production flows smoothly without sacrificing quality. Ribbon formation, FRP 05 style lines, and inline proof testing are pivotal in high-throughput settings.
Creating fiber ribbons starts with precise fiber spacing and placement. Machines dispense a slim polymer bead to bond fibers, while tensioning systems counteract micro-bends. Rapid cure stations lock the bond for line-speed movement. Proper glue management preserves optical quality and supports subsequent processing.
FRP 05 style lines are ideal for large-scale production. They can craft ribbons with up to 24 fibers at speeds hitting 1,000 m/min. They unite precise tension, accurate ferrules, and synced capstans. Fiber pitch/alignment stay consistent across the process. Thus, FRP 05 is a dependable choice for CO/FTTH ribbon supply.
Inline proof testing ensures ribbon quality. It involves 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 instant feedback reduces waste and blocks faulty ribbons from progressing to cable assembly.
Ribbon lines can also incorporate integrated marking and color coding. IDs survive later processing. Together, coding + proof tests improve traceability and QC. Syncing glue/formation/testing yields clear benefits for throughput.
