Modern ribbon lines combine coated fibers into a flat ribbon. It precisely controls geometry and attenuation. Manufacturers depend on 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.
Creating fiber ribbons starts with precise fiber spacing and placement. A thin adhesive bead bonds fibers; tensioning combats 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. 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 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 minimizes waste and prevents 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 simplifies quality control. Syncing glue/formation/testing yields clear benefits for throughput.
