High-Speed Ribbon Lines & Production
Modern ribbon lines combine coated fibers into a flat ribbon. It precisely controls geometry and attenuation. Key enablers include precision alignment, controlled glue, and fast curing. Production flows smoothly without sacrificing quality. FRP 05 formation lines and inline proof tests are critical at scale.
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. These systems merge 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 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. Together, coding + proof tests improve traceability and QC. Syncing glue/formation/testing yields clear benefits for throughput.
