High-Speed Ribbon Lines & Production
The modern fiber ribbon line combines coated fibers into a unified, flat ribbon. Geometry and attenuation are tightly controlled. Manufacturers depend on precise alignment, controlled glue application, and rapid curing. This ensures production flowing without compromising quality. FRP 05 formation lines and inline proof tests are critical at scale.
Ribbon creation begins with exact spacing and placement. A thin adhesive bead bonds fibers; tensioning combats 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 excel in 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. This delivers 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. 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. Instant feedback cuts waste and stops bad ribbons before cabling.
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.
