High-Speed Ribbon Lines & Production
The modern fiber ribbon line combines coated fibers into a unified, flat ribbon. Geometry and attenuation are tightly controlled. Key enablers include precision alignment, controlled glue, and fast curing. Production flows smoothly without sacrificing quality. Ribbon formation, FRP 05 style lines, and inline proof testing are critical 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. Controlled glue keeps optical quality and eases downstream steps.
FRP 05 style lines are ideal for large-scale production. Up to 24 fibers at ~1,000 m/min is achievable. These systems combine refined tension control, high-accuracy ferrules, and coordinated capstans. Fiber pitch/alignment stay consistent across the process. The FRP 05 line, therefore, is a dependable solution for central-office and FTTH ribbon supply networks.
Inline proof test confirms ribbon quality. Test heads check tensile/continuity immediately post-formation. 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 can also incorporate integrated marking and color coding. This way, identifiers remain intact through subsequent processing. Together, coding + proof tests improve traceability and QC. For entities seeking high output and efficiency, syncing glueing, formation, and testing yields clear benefits.
